SUPPLEMENTARY INFORMATION: 

Role of Critical Habitat in Actual 

Practice of Administering and 

Implementing the Act 

Attention to and protection of habitat 

is paramount to successful conservation 

actions. The role that designation of 

critical habitat plays in protecting 

habitat of listed species, however, is 

often misunderstood. As discussed in 

more detail below in the discussion of 

exclusions under ESA section 4(b)(2), 

there are significant limitations on the 

regulatory effect of critical habitat 

designation under ESA section 7(a)(2). 

In brief, (1) designation provides 

additional protection to habitat only 

where there is a Federal nexus; (2) the 

protection is relevant only when, in the 

absence of designation, destruction or 

adverse modification of the critical 

habitat would in fact take place (in other 

words, other statutory or regulatory 

protections, policies, or other factors 

relevant to agency decision-making 

would not prevent the destruction or 

adverse modification); and (3) 

designation of critical habitat triggers 

the prohibition of destruction or adverse 

modification of that habitat, but it does 

not require specific actions to restore or 

improve habitat. 

As of September 22, 2006, only 475 

species, or 36 percent of the 1,310 listed 

species in the U.S. under the 

jurisdiction of the Service, have 

designated critical habitat. We address 

the habitat needs of all 1,311 listed 

species through conservation 

mechanisms such as listing, section 7 

consultations, the Section 4 recovery 

planning process, the Section 9 

protective prohibitions of unauthorized 

take, Section 6 funding to the States, the 

Section 10 incidental take permit 

process, and cooperative, nonregulatory 

efforts with private landowners. The 

Service believes that it is these measures 

that may make the difference between 

extinction and survival for many 

species. 

In considering exclusions of areas 

originally proposed for designation, we 

evaluated the benefits of designation in 

light of Gifford Pinchot Task Force v. 

United States Fish and Wildlife Service. 

In that case, the Ninth Circuit 

invalidated the Service’s regulation 

defining ‘‘destruction or adverse 

modification of critical habitat.’’ In 

response, on December 9, 2004, the 

Director issued guidance to be 

considered in making section 7 adverse 

modification determinations. This 

critical habitat designation does not use 

the invalidated regulation in our 

consideration of the benefits of 

including areas in this final designation. 

The Service will carefully manage 

future consultations that analyze 

impacts to designated critical habitat, 

particularly those that appear to be 

resulting in an adverse modification 

determination. Such consultations will 

be reviewed by the Regional Office prior 

to finalizing to ensure that an adequate 

analysis has been conducted that is 

informed by the Director’s guidance. 

On the other hand, to the extent that 

designation of critical habitat provides 

protection, that protection can come at 

significant social and economic cost. In 

addition, the mere administrative 

process of designating critical habitat is 

expensive, time-consuming, and 

controversial. The current statutory 

framework of critical habitat, combined 

with past judicial interpretations of the 

statute, make critical habitat the subject 

of excessive litigation. As a result, 

critical habitat designations are driven 

by litigation and courts rather than 

biology, and made at a time and under 

a time frame that limits our ability to 

obtain and evaluate the scientific and 

other information required to make the 

designation most meaningful. 

In light of these circumstances, the 

Service believes that additional agency 

discretion would allow our focus to 

return to those actions that provide the 

greatest benefit to the species most in 

need of protection. 

Procedural and Resource Difficulties in 

Designating Critical Habitat 

We have been inundated with 

lawsuits for our failure to designate 

critical habitat, and we face a growing 

number of lawsuits challenging critical 

habitat determinations once they are 

made. These lawsuits have subjected the 

Service to an ever-increasing series of 

court orders and court-approved 

settlement agreements, compliance with 

which now consumes nearly the entire 

listing program budget. This leaves the 

Service with little ability to prioritize its 

activities to direct scarce listing 

resources to the listing program actions 

with the most biologically urgent 

species conservation needs. 

The consequence of the critical 

habitat litigation activity is that limited 

listing funds are used to defend active 

lawsuits, to respond to Notices of Intent 

(NOIs) to sue relative to critical habitat, 

and to comply with the growing number 

of adverse court orders. As a result, 

listing petition responses, the Service’s 

own proposals to list critically 

imperiled species, and final listing 

determinations on existing proposals are 

all significantly delayed. 

The accelerated schedules of courtordered designations have left the 

Service with limited ability to provide 

for public participation or to ensure a 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63863 

defect-free rulemaking process before 

making decisions on listing and critical 

habitat proposals, due to the risks 

associated with noncompliance with 

judicially imposed deadlines. This in 

turn fosters a second round of litigation 

in which those who fear adverse 

impacts from critical habitat 

designations challenge those 

designations. The cycle of litigation 

appears endless, and is very expensive, 

thus diverting resources from 

conservation actions that may provide 

relatively more benefit to imperiled 

species. 

The costs resulting from the 

designation include legal costs; the cost 

of preparation and publication of the 

designation; the analysis of the 

economic effects and the cost of 

requesting and responding to public 

comment; and in some cases the costs 

of compliance with the National 

Environmental Policy Act (NEPA). 

These costs, which are not required for 

many other conservation actions, 

directly reduce the funds available for 

direct and tangible conservation actions. 

Background 

In this rule, it is our intent to discuss 

only those topics directly relevant to the 

designation of critical habitat. For more 

information on the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

Kincaidii, and Erigeron decumbens var. 

decumbens, refer to the final listing rule 

published in the Federal Register on 

January 25, 2000 (65 FR 3875), or the 

proposed critical habitat rule published 

in the Federal Register on November 2, 

2005 (70 FR 66492). Provided below is 

a general overview of the habitat 

requirements of Fender’s blue butterfly, 

L. sulphureus ssp. Kincaidii, and E. 

decumbens var. decumbens. 

These species occur in wet prairie, 

upland prairie, and oak savanna habitats 

(collectively referred to as prairie 

habitat) that were once more widely 

distributed across western Oregon and 

southwestern Washington (Clark 1996, 

p. 8; Schultz et al. 2003, p. 69; Wilson 

et al. 2003, p. 79). Prairie habitat has 

been reduced to less than one percent of 

pre-settlement distribution (Hammond 

and Wilson 1993, p. 2), making the 

ecosystem among the most endangered 

in the United States (Noss et al. 1995, 

p. 67). The decline in these habitats and 

their increased fragmentation have led 

to the decline of many native prairie 

plants and animals (Wilson 1998a, p. 2 

and 1998b, p. 1). Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens are 

among the rarest of the native species 

dependent on this unique habitat type 

and are known to co-occur within the 

boundaries of some remnant prairie 

locations. 

Various descriptions of prairie 

habitats have been published over the 

years and they usually vary in their 

division of communities and the 

dominant species present in each 

community (Jackson 1996, p. 2). We 

describe two habitat types, wet prairie 

and upland prairie, and define these by 

describing the plant communities 

reported co-occurring with the Fender’s 

blue butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens. 

Upland prairie (including oak 

savanna) habitat occurs on well-drained 

soils and is characterized by a short 

grass stature dominated by native bunch 

grasses and forbs (Wilson 1998a, p. 2; 

Wilson et al. 2003, p. 79). Wet prairies 

are seasonally flooded ecosystems 

occurring on both poorly drained soil 

types and well-drained soils where 

shallow bedrock impedes drainage 

(Wilson 1998b, p. 1). Although wet 

prairie soils dry out during typical 

summer droughts, they have soils with 

hydric characteristics (i.e., soils formed 

under conditions of water saturation, 

flooding, or ponding long enough to 

develop anaerobic conditions) that 

support facultative or obligate wetland 

plant species (Wilson 1998b, p. 1). 

Fender’s blue butterfly and Lupinus 

sulphureus ssp. kincaidii 

The Fender’s blue butterfly and 

Lupinus sulphureus ssp. kincaidii 

populations primarily occur on early 

seral (one stage in a sequential 

progression) upland prairie habitat with 

plant species including but not limited 

to: Achillea millefolium (common 

yarrow), Aster hallii (Hall’s aster), 

Brodiaea congesta (Brodiaea), Bromus 

carinatus (California brome), 

Calochortus tolmiei (Cat’s ear, Tolmie 

star-tulip), Carex tumulicola (splitawn 

sedge), Cirsium callilepis (fewleaf 

thistle), Danthonia californica 

(California oatgrass), Elymus glaucus 

(blue wildrye), Eriophyllum lanatum 

(common woolly sunflower, Oregon 

sunshine), Festuca californica 

(California fescue), Festuca roemeri 

(Roemer’s fescue), Fragaria virginiana 

(Virginia strawberry), Geranium 

oreganum (Oregon geranium), Grindelia 

integrifolia (gumweed), Lomatium 

nudicaule (barestemmed desert parsley), 

Luzula campestris (wood rush), 

Prunella vulgaris (common selfheal), 

Sanicula crassicaulis (Pacific 

blacksnakeroot), Sidalcea virgata (rose 

checkermallow and dwarf 

checkerbloom), Silene hookeri (Hooker’s 

silene), and Wyethia angustifolia 

(California compassplant) (Wilson 

1998b, pp. 2–7; Kaye in litt.a, p. 2). 

Many of these associated species are 

considered indicators for upland prairie 

habitat (Schultz et al. 2003, p. 65; 

Wilson et al. 2003, p. 79). 

The Fender’s blue butterfly habitat 

requirements include a larval host plant 

(i.e., Lupinus sulphureus ssp. kincaidii, 

L. arbustus (spurred lupine), and L. 

albicaulis (sickle-keeled lupine), native 

forbs for adult nectar sources, and 

native grasses that comprise short-grass 

upland prairies (Wilson et al. 1997, p. 

3; Schultz 2001, p. 1008). These 

requirements are considered essential to 

the survival and conservation of these 

species (Wilson et al. 2003, p. 79). 

Lupinus sulphureus ssp. kincaidii is a 

primary larval host plant for the 

Fender’s blue butterfly and is utilized 

by the butterfly for oviposition (laying 

eggs) and as a larval food source 

(Schultz et al. 2003, p. 64; Wilson et al. 

2003, pp. 73, 77). Adult Fender’s blue 

butterflies use nectar sources in wet 

prairie habitat that occur near their host 

plant habitat. The Fender’s blue 

butterfly is more vigorous in full sun 

conditions (Schultz et al. 2003, p. 68), 

which are important for adult butterflies 

to seek out nectar, search for a mate, 

oviposit, and disperse (Severns in prep. 

Manuscript, pp. 1, 3, 13–19). The 

Fender’s blue butterfly appears to have 

limited dispersal ability, with most 

dispersing adults likely remaining 

within approximately 1.2 miles (mi) (2 

kilometers (km)) of their natal lupine 

patch (Schultz 1998, p. 284). The 

maximum dispersal distance reported 

for the Fender’s blue butterfly is 2 mi 

(3.2 km) (Severns 2004, p. 4). 

Lupinus sulphureus ssp. kincaidii 

habitat is generally described as prairie 

or open areas, and this species is 

typically unable to survive prolonged 

periods of shade (Wilson et al. 2003, p. 

79). However, populations of L. 

sulphureus ssp. kincaidii occurring in 

Douglas County, Oregon, have been 

documented as occurring in atypical 

habitat for the species (Barnes 2004, p. 

102). The Douglas County populations 

are in wooded areas with canopy cover 

ranging from 50 to 80 percent (Barnes 

2004, p. 102) and dominated by species 

such as: Arbutus menziesii (Pacific 

madrone), Arctostaphylos columbiana 

(hairy manzanita), Calocedrus decurrens 

(incense cedar), Calochortus tolmiei 

(Cat’s ear, Tolmie star-tulip), 

Canadanthus modestus (giant mountain 

aster), Ceanothus cuneatusa 

(buckbrush), Cerastium arvense (field 

chickweed), Cynosurus echinatus 

(bristly dogstail grass), Daucus carota 

(Queen Anne’s Lace, wild carrot), 

Dichelostemma capitatum (bluedicks), 

Festuca californica (California fescue),

Festuca roemeri (Roemer’s fescue), 

Fragaria vesca (woodland strawberry), 

Hieracium albiflorum (white

(Friedman in litt.a, p.1; Friedman in 

litt.b, p.1). 

Lupinus sulphureus ssp. kincaidii is a 

low-growing herbaceous perennial with 

large individual plant clones (Wilson et 

al. 2003, p. 73). Excavation efforts 

indicate that above-ground vegetation 

33 feet (10 m) or more apart can be 

interconnected by below-ground stems. 

The species is long-lived with lateral 

growth rates, suggesting that some 

plants could be several decades old 

(Wilson et al. 2003, p. 73). Lupinus 

sulphureus ssp. kincaidii clones are 

scattered in patches across the prairie 

habitat and intermixed with several 

other prairie-associated plant species. 

Lupinus sulphureus ssp. kincaidii is a 

primary larval host plant for the 

Fender’s blue butterfly and is utilized 

by the butterfly for oviposition (laying 

eggs) and as a larval food source 

(Schultz et al. 2003, p. 64; Wilson et al. 

2003, pp. 73, 77). 

Erigeron decumbens var. decumbens 

Erigeron decumbens var. decumbens 

grows in wet prairies occurring on 

relatively impermeable soils. Wet 

prairie habitat supporting Erigeron 

decumbens var. decumbens is typically 

defined by the plant species cooccurring with the plant including, but 

not limited to: Anthoxanthum odoratum 

(sweet vernalgrass), Aster curtus (whitetop aster), Aster hallii (Hall’s aster), 

Brodiaea coronaria (crown brodiaea), 

Camassia quamash (common camas), 

Danthonia californica (California 

oatgrass), Deschampsia caespitosa 

(tufted hairgrass), Festuca arundinacea 

(tall fescue), Grindelia integrifolia 

(gumweed), Holcus lanatus (velvet 

grass), Horkelia congesta (Sierra 

horkelia), Saxifraga integrifolia (bog 

saxifrage), Lomatium bradshawii 

(Bradshaw’s lomatium), Luzula 

campestris (wood rush), Panicum 

capillare (witchgrass), Potentilla gracilis 

(slender cinquefoil), Prunella vulgaris 

(common selfheal) and Sisyrinchium 

angustifolium (narrowleaf blue-eyed 

grass) (Clark et al. 1993, p. 18; Clark et 

al. 1995a, p. 1, 1995b, p. 1; Jackson 

1996, p. 14; Clark 2000, p. 3). Erigeron 

decumbens var. decumbens also grows 

in upland prairies as previously 

described (Clark et al. 1993, p. 18; Clark 

et al. 1995a, p. 1; Jackson 1996, p. 18; 

Clark 2000, p. 3). 

Erigeron decumbens var. decumbens 

typically occurs where woody cover is 

nearly absent and where herbaceous 

vegetation cover is low in stature 

relative to the surrounding areas (Clark 

et al. 1993, pp. 21, 22). Erigeron 

decumbens var. decumbens is a lowgrowing (6–24 inches (in) (15–60 

centimeters (cm))) herbaceous perennial 

occurring in clumps of genetically 

identical ramets (i.e., a vegetatively 

reproduced copy of the parent plant) 

that are typically patchy in distribution 

across the prairie habitat (Clark et al. 

1993, p. 23). These plants are 

intermixed with several associated 

species which are considered indicator 

species for the prairie habitat (Clark et 

al. 1993, p. 18). 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. Kincaidii, and Erigeron 

decumbens var. decumbens populations 

historically functioned as 

metapopulations in the more 

widespread prairie habitat (Jackson 

1996, p. 20; Liston et al. 1995, p. 318; 

Schultz 1998, p. 285; and Severns 

2003a, p. 221). Currently, most 

populations of these species are isolated 

from neighboring populations, and 

interactions between populations are 

thought to be rare events (Jackson 1996, 

p. 6; Schultz 1998, p. 286; Severns 

2003a, p. 222). Recovery will require 

reestablishing connected populations by 

restoring habitat networks (Kaye, in 

litt.b, 2005, p. 1; Schultz et al. 2003, p. 

61; Severns 2003a, p. 227). In this 

document, we define ‘‘habitat 

networks’’ as prairie habitat that can 

support connected populations and 

function as metapopulations. 

Previous Federal Actions 

On April 23, 2003, a complaint was 

filed against the Service (CV 03 513 JE 

(D. Or.)) for failure to designate critical 

habitat for the Fender’s blue butterfly, 

Lupinus sulphureus ssp. Kincaidii, and 

Erigeron decumbens var. decumbens. In 

December 2003, a settlement agreement 

resulted in a schedule for the Service to 

submit a proposed critical habitat rule 

to the Federal Register by October 15, 

2005, and a final rule by October 15, 

2006. 

On November 2, 2005, a proposed 

rule to designate critical habitat for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. Kincaidii, and Erigeron 

decumbens var. decumbens was 

published in the Federal Register (70 

FR 66492). The initial comment period 

closed on January 3, 2006. On April 21, 

2006, we published a notice in the 

Federal Register announcing the 

reopening of the comment period and 

the public hearing for the proposed 

critical habitat for the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

Kincaidii, and Erigeron decumbens var. 

decumbens (71 FR 20636). On June 15, 

2006, we published a notice in the 

Federal Register announcing the 

availability of the draft economic 

analysis of the proposed designation of 

critical habitat for these species and a 

reopening of the public comment period 

(71 FR 34566). The third public 

comment period closed on June 30, 

2006. For more information on previous 

Federal actions concerning Fender’s 

blue butterfly, L. sulphureus ssp. 

Kincaidii, and E. decumbens var. 

decumbens refer to the November 2, 

2005, proposed rule (70 FR 66492). 

Summary of Comments and 

Recommendations 

We requested written comments from 

the public on the proposed designation 

of critical habitat for Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

Kincaidii, and Erigeron decumbens var. 

decumbens in the proposed rule 

published on November 2, 2005 (70 FR 

66492). We also contacted appropriate 

Federal, State, and local agencies; 

scientific organizations; and other 

interested parties and invited them to 

comment on the proposed rule. In 

addition, we held a public hearing on 

May 9, 2006, in Corvallis, Oregon. No 

comments were received during the 

public hearing. 

During the comment period that 

opened on November 2, 2005, and 

closed on January 3, 2006, we received 

72 comments directly addressing the 

proposed critical habitat designation: 5 

from peer reviewers, 3 from Federal 

agencies, and 64 from organizations or 

individuals. During the comment period 

that opened on April 21, 2006, and 

closed on May 19, 2006, we received an 

additional 11 comments directly 

addressing the proposed critical habitat 

designation: one from a peer reviewer, 

one from a Federal agency, and nine 

from organizations or individuals. 

During the comment period that opened 

on June 15, 2006, and closed on June 30, 

2006, we received 12 comments directly 

addressing the proposed critical habitat 

designation and the draft economic 

analysis. Of these latter comments, one 

was from a peer reviewer and 11 were 

from organizations or individuals. The 

received comments were grouped into 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63865 

six general categories specifically 

relating to the proposed critical habitat 

designation or draft economic analysis 

for Fender’s blue butterfly, L. 

sulphureus ssp. Kincaidii, and E. 

decumbens var. decumbens. The 

comments are addressed in the 

following summary and incorporated 

into the final rule as appropriate. 

Peer Review 

In accordance with our peer review 

policy published on July 1, 1994 (59 FR 

34270), we solicited expert opinions 

from eight knowledgeable individuals 

with scientific expertise that included 

familiarity with the species, the 

geographic region in which the species 

occur, and conservation biology 

principles. Five of the eight peer 

reviewers responded. The peer 

reviewers generally concurred with our 

methods and conclusions and provided 

additional information, clarifications, 

and suggestions to improve the final 

critical habitat rule. 

We reviewed all comments received 

from the peer reviewers and the public 

for substantive issues and new 

information regarding critical habitat for 

the Fender’s blue butterfly, Lupinus 

sulphureus ssp. Kincaidii, and Erigeron 

decumbens var. decumbens. Peer review 

comments are addressed in the 

following summary and incorporated 

into the final rule as appropriate. 

Peer Review Comments Related to Life 

History, Habitat Characteristics, and 

Ecological Considerations 

1. Comment: During the 2005 field 

season, one peer reviewer reported 

finding a Fender’s blue butterfly 

population that has become successfully 

established at the Deer Creek County 

Park in Yamhill County within a large 

patch of Lupinus sulphureus ssp. 

Kincaidii, and has been growing and 

expanding rapidly over the past few 

years. The peer reviewer recommended 

adding this site to the critical habitat 

designation in association with the 

Gopher Valley metapopulation since the 

site is only 1 mile (1.6 kilometers) south 

of units FBB–2 and KL–3. 

Our Response: At the time we 

proposed critical habitat, the best 

scientific information available 

identified 0.2 acre (ac) (0.1 hectare (ha)) 

of Lupinus sulphureus ssp. kincaidii 

habitat occuring in Deer Creek County 

Park. We did not have information 

describing available surrounding prairie 

habitat; therefore, it did not meet our 

criteria at the time of our proposal. We 

have been unable to verify that these 

sites meet our criteria. 

2. Comment: One peer reviewer 

recommended deleting the critical 

habitat unit on Monmouth Highway 

(FBB–6B) within unit FBB–6 in Polk 

County. This peer reviewer stated that 

this Fender’s blue butterfly population 

is located on a disturbed agricultural 

field, which has been replanted with 

young conifer trees. The reviewer 

believes that eventually the trees will 

out-compete the existing lupine species 

and eliminate the butterfly from the site. 

Our Response: FBB–6B meets our 

criteria for inclusion because it is the 

largest known population of Fender’s 

blue butterfly in this portion of the 

species’ range and contains primary 

constituent elements essential to the 

conservation of the species. We do not 

know the extent of tree planting on the 

site or how much habitat may be 

affected; however the site does provide 

PCEs despite the fact it has been planted 

to some degree. Other sites that were 

planted with young conifers for 

commercial Christmas tree farms in the 

early 1990’s still support butterflies 

with recently reported increasing 

populations. Periodic Christmas tree 

harvest may act as a disturbance that 

opens the habitat and allows the lupine 

to spread back into these areas with 

butterfly populations increasing in 

response to the additional available 

habitat. These are disturbance 

dependent species. Since butterfly 

numbers at this site have been estimated 

at substantially higher numbers from 

2003 to 2005, we feel that this site 

should remain in the designation. 

During the development of the proposed 

rule, another peer reviewer stated that 

this site could serve as an important 

stepping-stone habitat (see Schultz 

1998, p. 291) and enhance the genetic 

exchange among Fender’s blue butterfly 

populations at other sites. Additionally, 

FBB–6A provides Lupinus sulphureus 

ssp. kincaidii habitat within the 

butterfly’s average dispersal distance, 

which may serve as a stepping stone 

between FBB–6 and FBB–5. This unit 

has the features that are essential to the 

conservation of the butterfly and is, 

therefore, included in this final 

designation. 

3. Comment: One peer reviewer 

recommended that the maximum 

dispersal distance for Fender’s blue 

butterfly be changed to 1.9 mi (3.0 km) 

based on an observed colonization 

event. 

Our Response: We are using a 

Fender’s blue butterfly average adult 

lifetime movement distance of 1.2 mi (2 

km) based on a behavioral study by 

Schultz (1998, pp. 287–290). We 

acknowledge that the Fender’s blue 

butterfly is capable of moving greater 

distances, but data with which to 

determine how frequently such 

movements may occur is currently 

lacking. Therefore, based on the above 

study, we retained the use of the 1.2 mi 

(2 km) distance as a more typical and 

conservative estimate of adult butterfly 

movement. 

4. Comment: One peer reviewer 

wanted us to clarify actions that would 

further isolate populations of Fender’s 

blue butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens as discussed under Section 

7 Consultation in the proposed rule. The 

peer reviewer stated that current 

habitats for these species are essentially 

isolated and data for the two plants 

species are unavailable to determine 

how the listed actions would cause 

further isolation, especially associated 

with pollinator travel and seed dispersal 

distances. 

Our Response: In the proposed rule, 

we stated that if critical habitat units for 

the plants are located more than 5 mi (8 

km) apart, or if critical habitat units for 

Fender’s blue butterfly are located more 

than 1.2 mi (2 km) apart, then actions 

in the areas separating the units would 

not be considered to further isolate the 

species. 

5. Comment: One peer reviewer stated 

that we should include the pollinators 

for Erigeron decumbens var. decumbens 

as a primary constituent element similar 

to what we did for Lupinus sulphureus 

ssp. kincaidii. 

Our Response: There is very little data 

that has been published or reported in 

the literature on this species, including 

requirements for reproduction. 

Although insect pollination has been 

documented as facilitating sexual 

reproduction, it has not been reported as 

essential to the reproduction of Erigeron 

decumbens var. decumbens. Therefore, 

because we were not able to determine 

the specific pollinator essential to the 

conservation of the species, we did not 

include the presence of insect 

outcrossing pollinators as a primary 

constituent element for the species. 

Comments From the Public Related to 

Life History, Habitat Characteristics, 

and Ecological Considerations 

6. Comment: An increase in 

urbanization within the West Eugene 

area could create barriers to dispersal 

for the Fender’s blue butterfly between 

core and satellite areas. 

Our Response: We agree that 

increased urbanization may have direct 

and indirect effects (e.g., mortality from 

vehicle collisions and increased habitat 

loss) on Fender’s blue butterfly 

dispersal, but specific scientific studies 

addressing the effects of urbanization on 

Fender’s blue butterfly dispersal are not 

available. We will evaluate potential 


rwilkins on PROD1PC63 with RULES_2
63866 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

future impacts to the designated critical 

habitat on specific projects through the 

section 7 consultation process. 

7. Comment: A number of 

commenters stated that the effects of 

climate variability, natural flooding, and 

water management are not taken into 

consideration in the designation. 

Specifically, these events may result in 

hydrologic changes; accordingly, the 

critical habitat designation should cover 

a broader range of topographic 

elevation. Specific recommendations 

were made to include additional habitat 

for Erigeron decumbens var. decumbens 

to address a variety of concerns, such as 

elevation, topography, and slope. 

Our Response: While we agree that 

climate variability could play a role in 

future distributions of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens, we are not aware of 

scientific information that specifically 

addresses the effects of these events on 

these species or how to modify the 

designation to address these potential 

threats. We worked with local land 

managers and scientific experts to 

identify the extent of prairie habitat that 

supported E. decumbens var. 

decumbens populations, and that also 

met our criteria for designation. 

8. Comment: Forest succession 

between core populations of Fender’s 

blue butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens could create smaller 

genetically isolated populations that 

would put them at a greater risk of local 

extirpation from the lack of genetic 

diversity. To address this concern, the 

commenter recommended designating 

lupine patches for butterfly core areas 

with recovery management criteria to 

reduce intervening forest or ensure open 

prairie corridors are available through 

the forest. Additionally, the commenter 

was concerned about the uncertainty of 

lake bays as barriers to butterfly 

dispersal. 

Our Response: Gene flow among 

populations of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens could be partially or 

completely restricted depending on the 

degree of intervening forest and the size 

of a given lake bay. The commenter 

cited a personal communication with 

peer reviewer Paul Severns, 

documenting Severns’ observation of 

Fender’s blue butterflies flying over tall 

oak trees, which further shows the 

uncertainty of this potential risk. To our 

knowledge, there are no currently 

available scientific studies that have 

been completed for these species to 

further our understanding of this 

potential gene flow issue. For the 

Fender’s blue butterfly, McIntire et al. 

(2006, p. 27) states that they do not 

know butterfly response to barriers such 

as woodlands, light industrial 

development, and roads. Therefore, they 

do not know the effects these elements 

may have on dispersal. McIntire et al. 

(2006, p. 27) notes that if elements such 

as woodlands or topography change 

butterfly movement or mortality, then 

connectivity would likely be affected. 

For these reasons, researchers are 

currently undertaking field studies to 

estimate these potential effects. 

However, as these studies are not yet 

complete, we cannot rely on them for 

this designation. 

9. Comment: The proposed critical 

habitat stated that land within the 

Willamette Valley was ‘‘subjected to fire 

suppression,’’ which assumes that 

naturally occurring fires routinely 

burned in the valley and were 

suppressed by humans. To the contrary, 

the commenter believes that Native 

Americans converted the valley to 

agricultural lands when they began 

routinely burning to enhance the growth 

of harvestable food crops. This 

commenter stated that without human 

intervention, Fender’s blue butterfly 

habitat would not have existed to any 

great extent and wanted to know what 

scientific evidence is available to prove 

that the butterfly was once more widely 

distributed in the Willamette Valley. 

Our Response: Based on information 

in the final listing rule for the Fender’s 

blue butterfly (65 FR 3875), the precise 

historic distribution of the butterfly is 

unknown due to limited information 

collected on this species prior to its 

description in 1931. However, early 

records indicate that before European 

settlement, the landscape of the 

Willamette Valley was largely an open 

expanse of prairie and savannah habitat 

(Altman et al. 2001, p. 262; Franklin and 

Dyrness 1973, p. 119). Given the greater 

amount of upland prairie patches, we 

assumed that the butterfly and Lupinus 

sulphureus ssp. kincaidii were also 

more widely distributed (Schultz 1998, 

p. 290–291; Wilson et al. 2003, p. 79). 

However, as stated previously, we do 

not know the historic distribution of 

these species, and it is possible that 

distribution was always patchy. This 

assumption is independent of whether 

prairie habitats were created or 

maintained under natural or humaninduced conditions. 

Comments From the Public Related to 

Critical Habitat, Primary Constituent 

Elements, and Methodology 

10. Comment: Several commenters 

recommended that we designate 

multiple stepping-stone pathways for 

Fender’s blue butterflies to ensure 

connectivity among critical habitat units 

and that we designate additional large 

core areas to ensure that some of the 

areas achieve stable butterfly 

populations. Additionally, commenters 

were concerned about the habitat 

condition of specific units designated in 

West Eugene. One commenter suggested 

specific sites for inclusion in West 

Eugene to address the following 

concerns: Stepping-stone redundancy, 

climatic variability, connectivity, 

elevation diversity, and population 

expansion. The commenters also 

suggested using a rule set for selecting 

habitats based on fine scale subwatersheds. 

Our Response: We used the best 

available scientific information and 

included occupied Fender’s blue 

butterfly habitat identified as having the 

features that are essential for reestablishing a viable, connected 

metapopulation in the Eugene, Oregon 

area (McIntire et al. 2006, in review, 

pp. 20–22). Although we recognize that 

additional habitat may further 

contribute to recovery, our best 

available information (McIntire et al. 

2006, in review, p. 20–22) does not 

identify the commenter’s suggested 

areas as appropriate for designation as 

critical habitat for the Fender’s blue 

butterfly. Outside of Eugene, Oregon, 

the best available information is not 

sufficient to identify stepping-stone 

pathways, thus, none were designated. 

Additional Lupinus sulphureus ssp. 

kincaidii habitat will likely be needed 

for recovery; however, we are unaware 

of any additional lupine patches that 

meet the minimum patch size within 

the pollinator distance criteria. The best 

available scientific information (Gisler 

et al., in litt., 2005, pp. 4, 5) defines 

criteria without regard to subwatershed. 

11. Comment: Several commenters 

stated that designated Lupinus 

sulphureus ssp. kincaidii patches 

should be closer together (1.2 mi (2 km)) 

to allow for more frequent crosspollination between patches by native 

pollinators. 

Our Response: We included occupied 

Lupinus sulphureus ssp. kincaidii sites 

that are within 5 mi (8 km) (based on 

the maximum flight distance of the nonnative honeybee) of a lupine core area 

and that met our minimum patch size of 

0.25 ac (0.1 ha). By using the 5 mi (8 

km) distance, we included lupine 

patches that are within 1.2 mi (2 km) of 

each other. 

12. Comment: We failed to designate 

sufficient critical habitat that would 

provide Lupinus sulphureus ssp. 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63867 

kincaidii the ability to colonize other 

areas, especially in response to threats 

from predation, parasites, and invasive 

plant species. One of the commenters 

made specific recommendations for the 

inclusion of unoccupied and occupied 

L. sulphureus ssp. kincaidii patches in 

the critical habitat designation to allow 

for increased lupine succession, 

regeneration, population stabilization, 

topographic relief, and improved 

pollination. 

Our Response: We included the 

prairie habitat occupied by Lupinus 

sulphureus ssp. kincaidii that met our 

selection criteria and believe that we 

have provided for the concerns listed in 

the comment. We agree that additional 

areas not included in this designation 

that did not meet our selection criteria 

for critical habitat may also be needed 

to recover the species. However, 

information currently available does not 

suggest that these specific areas have the 

features that are essential to the 

conservation of the species. 

13. Comment: No apparent biological 

reason exists for gaps between critical 

habitat units in the narrow waterway 

corridors for the Fender’s blue butterfly 

in Eugene, Oregon. This commenter and 

eight others made recommendations for 

the inclusion of additional Fender’s 

blue butterfly areas in the West Eugene 

area to address this issue and provide 

for species recovery. 

Our Response: We did not include 

waterways between critical habitat units 

because the distance between lupine 

patches supporting Fender’s blue 

butterflies exceeded the 1.2-m (2 km) 

average adult butterfly movement 

distance (Schultz 1998, pp. 288–290). 

Each unit includes all populations that 

are believed to be connected and 

functioning as a larger metapopulation 

given the current landscape. Schultz 

(1998, p. 291) documented that 

stepping-stones would be more 

beneficial to the butterfly than corridors, 

and McIntire et al. (2006, in review, pp. 

20–22) identified necessary butterfly 

stepping-stone habitat in Eugene, 

Oregon. Refer to the Summary of 

Changes from Proposed Rule section in 

this rule for more information on 

changes to the critical habitat 

designation for the butterfly. 

14. Comment: The inclusion of an 

additional habitat patch to unit KL–12B 

would allow for a more stable 

population of smaller Lupinus 

sulphureus ssp. kincaidii patches along 

the Amazon Channel. The U.S. Army 

Corps of Engineers (Corps) 

recommended including specific 

occupied sites they manage for L. 

sulphureus ssp. kincaidii. 

Our Response: We have not had 

enough time to evaluate all of the 

information regarding potential critical 

habitat sites that we received during the 

public comment periods to determine if 

these sites meet our criteria. 

15. Comment: The Eugene District of 

the Bureau of Land Managemnt (BLM) 

recommended including two newly 

discovered (June 2005) sites for Fender’s 

blue butterfly and Lupinus sulphureus 

ssp. kincaidii within their District’s 

upper Willamette resource area (Oak 

Basin). 

Our Response: We appreciate the 

BLMs’ recognition of the value of these 

sites; however, they did not meet our 

criteria for selection. 

16. Comment: Several commenters 

stated that the proposed critical habitat 

designation for the Fender’s blue 

butterfly or Lupinus sulphureus ssp. 

kincaidii included areas that 

overrepresent the extent of the habitat 

for these species. 

Our Response: We revised the critical 

habitat boundaries, as appropriate, 

based on information received during 

the comment period. Prairie habitat that 

contains one or more of the Fender’s 

blue butterfly primary constituent 

elements within 1.2 mi (2 km) of a 

butterfly population is considered 

occupied by the butterfly. Contiguous 

prairie habitat surrounding known 

populations of L. sulphureus ssp. 

kincaidii and E. decumbens var. 

decumbens is also considered occupied 

if it contained one or more of the 

species-specific primary constituent 

elements (see the Primary Constituent 

Elements and Criteria Used To Identify 

Critical Habitat sections). 

17. Comment: We erroneously 

excluded areas of Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens, including historic sites that 

are no longer extant, from the critical 

habitat designation. Additionally, the 

Army Corp of Engineers recommended 

including potential habitat sites they 

manage for L. sulphureus ssp. kincaidii 

and E. decumbens var. decumbens. 

Our Response: We recognize that 

areas outside of this designation will 

contribute to the recovery of Lupinus 

sulphureus ssp. kincaidii and Erigeron 

decumbens var. decumbens and 

appreciate the Army Corp of Engineers’

on-going efforts to manage for the 

species. However, not all sites that 

historically supported these species are 

considered to have the features that are 

essential to the conservation of the 

species. Some sites did not meet our 

criteria to be included in the final 

designation. 

18. Comment: The Roseburg District 

of the BLM stated that the atypical 

habitat conditions where Lupinus 

sulphureus ssp. kincaidii occurs in 

Douglas County is described 

inconsistently with regard to the shade 

tolerance of the species, and that the 

first lupine primary constituent element 

does not apply in Douglas County. 

Our Response: We agree, and have 

clarified the information in the 

Background, Primary Constituent 

Elements, and Criteria Used To Identify 

Critical Habitat sections of this rule to 

address BLM’s concerns associated with 

the atypical habitat conditions for 

Lupinus sulphureus ssp. kincaidii in 

Douglas County. Individual critical 

habitat units for L. sulphureus ssp. 

kincaidii do not have to contain all of 

the species-specific primary constituent 

elements, but must contain at least one 

of the primary constituent elements to 

support a portion of the species’ life 

history. The second primary constituent 

element for L. sulphureus ssp. kincaidii 

is associated with the critical habitat 

designation in Douglas County. We 

proposed critical habitat in Douglas 

County using the same criteria as in 

other areas, with the addition of atypical 

habitat conditions found in the county. 

Refer to the Primary Constituent 

Elements and Criteria Used To Identify 

Critical Habitat sections in this rule for 

more information on how we defined 

the critical habitat criteria for L. 

sulphureus ssp. kincaidii. 

19. Comment: The proposed critical 

habitat rule, including primary 

constituent elements, is too narrowly 

focused to protect the habitat essential 

for the long-term survival and recovery 

of the Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens. In addition, 

the designation should include low 

quality areas. 

Our Response: Most populations of 

the Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens have not 

been studied adequately to determine 

how best to restore functioning 

metapopulations in the highly 

fragmented prairie habitats within the 

Willamette Valley. We used the best 

available scientific information to 

determine primary constituent elements 

and critical habitat criteria for each 

species. We recognize that critical 

habitat designations, based on the 

species’ primary constituent elements 

and other criteria, may not include all 

areas that may be necessary for species 

recovery. Future research and recovery 

planning will likely identify other areas 

that will aid in recovery. We only 

included areas of sufficient quality that 


rwilkins on PROD1PC63 with RULES_2
63868 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

are able to sustain the species and have 

the features that are essential to the 

conservation of the species. (see the 

Criteria Used To Identify Critical 

Habitat section). 

Comments From the Public Related to 

the Act and Implementing Regulations 

20. Comment: The City of Eugene’s 

West Eugene Wetlands Plan and Bureau 

of Land Management’s West Eugene 

Wetlands Restoration Schedule do not 

include the level of special management 

considerations and protections provided 

under a critical habitat designation, and 

it would be inappropriate to exclude 

any area covered under these plans that 

would otherwise qualify as critical 

habitat. 

Our Response: We agree, while the 

City of Eugene’s West Eugene Wetlands 

Plan and Bureau of Land Management’s 

West Eugene Wetlands Restoration 

Schedule include general planning 

schedules for the area, they did not 

provide the specificity of management 

that we needed to evaluate under our 

section 4(b)(2) process. As these and 

other planning efforts progress, we will 

work with involved entities to address 

the conservation of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens. If we revise critical habitat 

in the future, we will revaluate the 

status of planning efforts. 

21. Comment: The Eugene District of 

the BLM requested that we consider (1) 

exempting all BLM-administered lands 

within the West Eugene Wetlands from 

the final critical habitat rule, or (2) 

exempting all actions under their 10- 

year schedule for restoration from 

further section 7 consultation on effects 

to critical habitat designations for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens. 

Our Response: Biological opinions 

resulting from a consultation are not in 

and of themselves a basis for exclusion. 

However, management plans that 

commit to specific appropriate 

management criteria, whether 

associated with a biological opinion or 

not, are considered for exclusion. We do 

not anticipate that further minimization 

measures on the West Eugene Wetlands 

Schedule Environmental Assessment 

(No. OR090–EA–05–03) will be required 

due to this final rule. 

22. Comment: The Eugene District of 

the BLM stated that the development of 

a wetland education center is planned 

for the Danebo site. BLM and several 

other commenters believe that the 

positive effects of public education on 

the values and vulnerability of wetland 

species outweigh the benefits of 

designating critical habitat at this site. 

Our Response: We agree that public 

outreach and voluntary conservation on 

wetlands and associated species in West 

Eugene is important. However, we have 

not been provided any project 

documention associated with a potential 

education center and are unable to 

assess whether the area has 

conservation in place that is comparable 

to designation as critical habitat. 

23. Comment: Several commenters 

stated that they are willing to 

voluntarily manage the habitat on their 

property for the Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens, 

but do not want to be included in the 

critical habitat designation because of 

increased regulatory burdens. Some 

commenters specifically suggested not 

designating private agricultural lands, 

and requested a description of proper 

prairie habitat management to 

understand how it would affect 

agricultural operations. 

Our Response: We support and 

appreciate the efforts that are being 

made by organizations and individuals 

to conserve listed species on their lands. 

When undertaking the process of 

designating critical habitat for a species, 

we evaluate lands defined by physical 

and biological features essential to the 

conservation of the species without 

regard to land ownership or land use. 

We will gladly evaluate conservation 

plans and efforts to determine if areas 

can be excluded because conservation is 

in place. At the time of this rule, we did 

not have conservation plans or other 

documents that would allow us to 

assess the adequacy of conservation on 

these specific lands. For a general 

description of proper management of 

prairie habitat, refer to the Special 

Management Considerations or 

Protections section of this rule. The 

specifics of management can vary from 

site to site, and we offer technical 

assistance to landowners in establishing 

management plans for conserving 

species. 

24. Comment: Commenters disagree 

with our statement that ‘‘the designation 

of statutory critical habitat provides 

little additional protection to most listed 

species.’’ Commenters also note several 

court decisions that have invalidated 

this position, which violates 

Congressional intent and the plain 

language of the Endangered Species Act. 

Our Response: In most cases, 

conservation mechanisms provided 

through section 7 consultations, section 

4 recovery planning process, section 9 

protective prohibitions of unauthorized 

take, section 6 funding to the States, 

section 10 incidental take permits, and 

cooperative programs with private and 

public landholders and tribal nations 

provide greater incentives and 

conservation benefits than designation 

of critical habitat. 

25. Comment: The City of Eugene 

identified several conservation 

accomplishments achieved through 

implementation of the West Eugene 

Wetlands Plan, including the outgrowth 

of the West Eugene Wetlands 

Partnership. The City provided 

suggestions for reducing the regulatory 

requirements associated with critical 

habitat designation on their property in 

order to increase their ability to 

effectively manage their lands. 

Our Response: We agree that the City 

of Eugene and its partners have 

significantly contributed to wetland 

conservation through the 

implementation of their wetland 

mitigation plan. The mitigation plan, 

however, is not specifically designed to 

protect and manage habitat for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens, and does 

not provide the specific management 

details needed to meet our section 

4(b)(2) requirements. 

Comments From States Related to 

Critical Habitat, Primary Constituent 

Elements, and Methodology 

26. Comment: The Washington 

Department of Natural Resources 

(WDNR) recommended that the Lewis 

County, Washington Lupinus 

sulphureus ssp. kincaidii parcels be 

excluded from the critical habitat 

designation. WDNR believes that the 

willingness of landowners to cooperate 

with the WDNR on species conservation 

may be negatively affected if 

landowners view the designation as a 

restriction on their ability to use the 

land. 

Our Response: We are excluding unit 

KL–1A from critical habitat designation 

based on the Lupinus sulphureus ssp. 

kincaidii conservation provisions 

documented in the landowner’s 

management plan with U.S. Department 

of Agriculture Natural Resources 

Conservation Service. For more 

information, see the ‘‘Application of 

Section 3(5)(A) and 4(a)(3) and 

Exclusions Under Section 4(b)(2) of the 

Act’’ section of the rule. Unit KL–1B is 

not eligible for exclusion because there 

is no current management or 

conservation plan for the species or the 

features essential to its conservation at 

this site.

Comments Related to Economic 

Analysis; and Other Relevant Impacts 

27. Comment: We received a comment 

stating that the draft economic analysis 

does not consider the impact of critical 

habitat designation on the conservation 

market (i.e., the supply, demand, and 

exchange of habitat through decisions 

by buyers and sellers); that designating 

critical habitat removes both the option 

for development and the appeal of the 

area for potential conservation land. The 

commenter believes the draft economic 

analysis only quantifies the former cost, 

and not the latter. 

Our Response: If landowners forgo the 

development of their land to conserve 

the habitat, their value for conservation 

is equal to or greater than the value of 

the development opportunity. The draft 

economic analysis measured this 

opportunity cost. The cost of acquiring 

conservation easements is captured in 

Section 4.0, which includes estimates of 

the cost of land use restrictions imposed 

on landowners by conservation efforts 

associated with the species. The lost 

land value (i.e., growth premium and 

option value) calculated in Section 4.0 

represents the underlying value of 

conservation easements that could be 

purchased in order to remove the 

development opportunity from the land 

and to protect the habitat. This same 

concept applies if the land is sold for 

conservation purposes (presumably at 

some market price). The market price 

for conservation would be set by the 

highest valued use for the land. The 

extent that critical habitat designation 

reduces the appeal of an area for 

potential conservation land, and results 

in a reduction in land value beyond the 

option for development measured by the 

draft economic analysis, is understated 

in the draft economic analysis. 

However, no evidence was provided 

indicating that critical habitat 

designation makes land less attractive 

for conservation. 

28. Comment: We should include the 

value of ecosystems in analyzing 

economic issues associated with the 

designation of critical habitat 

designations. 

Our Response: We recognize that the 

various functions of an ecosystem have 

value, but we are unable to 

meaningfully place an economic value 

on the biological attributes that function 

to make a viable ecosystem. The benefits 

of critical habitat are best expressed in 

biological terms, e.g., the conservation 

benefit provided to a species, which can 

then be weighed against the expected 

economic impacts of the rulemaking. 

The purpose of a critical habitat 

economic analysis is to assist the 

Secretary in deciding whether the 

benefits of exclusion outweigh the 

benefits of inclusion, and if areas should 

be excluded under section 4(b)(2) of the 

Act. We may not be able to 

quantitatively account for the value of 

ecosystems in analyzing economic 

issues related to the designation of 

critical habitat, but we have done so 

qualitatively in a manner that supports 

the Secretary’s exclusion analysis 

through the 4(b)(2) process. 

29. Comment: The economic analysis 

can not reasonably weigh the biological 

benefits of critical habitat designation 

without weighing its biological costs, 

such as habitat losses brought on as a 

result of the landowners’ beliefs that 

they have disincentives to maintain the 

habitat. The economic analysis 

dismisses these biological costs as rare, 

but the commenter believes they are 

potentially substantial. 

Our Response: In the proposed rule 

and draft economic analysis, we 

indicated that we did not expect the 

designation of critical habitat to provide 

significant additional regulatory or 

economic burdens or restrictions 

beyond those afforded the species 

pursuant to the Act. This assertion is 

based on the regulatory protections 

afforded to Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens as 

a result of their existing listed status, 

and the protections that status affords. 

Since all the lands designated as critical 

habitat are already occupied by one or 

more of species, there is little additional 

regulatory burden placed on private 

landowners. 

30. Comment: Other commenters 

stated the draft economic analysis does 

not assess the potential impacts to them 

as landowners if a vintner is 

discouraged from leasing or they are 

discouraged from developing a vineyard 

on their land in Polk County due to the 

critical habitat designation. 

Our Response: As described in 

Section 4.1 of the draft economic 

analysis, if development of a parcel of 

agriculture land is restricted, it will be 

worth less than its value in the 

previously unrestricted state. This loss 

of value is a cost to the landowner; with 

the magnitude of loss depending on the 

type of land use restriction imposed. 

Specifically, if a piece of land is 

restricted from any kind of use, all of its 

economic value will be lost. Based on 

recent sales transactions obtained from 

Farm Credit Services of agriculture land 

similar to the proposed critical habitat 

in Polk County (i.e., 49 sales during the 

period 2000 to 2005), a complete loss of 

economic value to the commenter’s land 

in Polk County could approach $8,000 

per acre. 

However, as stated in Section 4.0 of 

the draft economic analysis, this 

analysis assumes the agriculture use of 

privately owned land will be 

unrestricted, and the draft economic 

analysis only presents economic 

impacts to the commenter’s land related 

to the loss of development opportunity. 

In this case, the development impact 

measured in the draft economic analysis 

is nearly $6,600 per acre, 93 percent of 

their estimated land value. If a vineyard 

opportunity is restricted on private 

property in order to conserve species, 

there may be an additional loss in 

property value above that quantified in 

the draft economic analysis. 

31. Comment: The draft economic 

analysis does not calculate the lost farm 

and forest values associated with land 

development. Development destroys the 

farm or forest potential, eliminating a 

stream of economic benefits. This 

income and benefit stream is associated 

with land conservation and should be 

included among the economic benefits 

of critical habitat designation. 

Our Response: As described in 

Section 4.0 of the of the draft economic 

analysis, the existing agricultural use of 

the private land within the proposed 

critical habitat designation is assumed 

to remain unrestricted. While critical 

habitat designation may restrict 

development opportunities, depending 

on the existence of a Federal nexus, the 

ongoing use of the land for farming and 

forestry is expected to continue, is 

embedded in the land value, and is 

included in the economic analysis. 

32. Comment: The economic cost of 

recovering very small populations or 

populations that lack adequate habitat 

will be significantly greater than the 

cost of recovering populations with 

adequate habitat. Conserving rare plant 

species through the designation of 

critical habitat will also conserve other 

species. The effort to recover rare 

species should be considered when 

performing an economic analysis 

pursuant to the designation of critical 

habitat. 

Our Response: The economic costs of 

future recovery actions for species not 

addressed in the designation are 

independent of the economic impacts 

caused by the critical habitat 

designation, which is the focus of this 

economic analysis. It would be 

inappropriate for us to speculate on how 

an unknown suite of future recovery 

actions for other species might be made 

more or less costly as a result of the 

designation. 

33. Comment: The economic analysis 

exaggerated the economic costs of the 


rwilkins on PROD1PC63 with RULES_2
63870 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

critical habitat designation through 

sheer speculation. 

Our Response: To ensure that all 

possible potential economic impacts 

were given adequate consideration, we 

contacted all appropriate State and 

Federal agencies, Tribes, county 

governments, elected officials, and other 

interested parties and invited them to 

comment. In addition, we invited public 

comment through the publication of 

notices in several local newspapers. We 

provided notification of the draft 

economic analysis through telephone 

calls, letters, and news releases faxed or 

mailed to affected elected officials, local 

jurisdictions, and interest groups. We 

also published the draft economic 

analysis and associated material on our 

internet site (http://www.fws.gov/ 

oregonfwo/Species/ESA-Actions/ 

WillValleyPage.asp) following the 

draft’s release on June 15, 2006. In 

addition to inviting public comment on 

the proposed designation, the later 

notices announced the dates and times 

of a public hearing on the proposed 

designation. Any economic impacts 

described in the draft economic analysis 

are a direct result of this extensive effort 

to collect data on the actual potential 

impacts. While some potential impacts 

are less likely than others, all impacts 

described result from following a 

consistent approach to gathering this 

information. 

34. Comment: The economic analysis 

illegally attributed costs associated with 

the species listing to costs of critical 

habitat designation. 

Our Response: The primary purpose 

of the economic analysis is to estimate 

the potential economic impacts 

associated with the designation of 

critical habitat for these three species. 

We interpret the Act to require that the 

economic analysis include all of the 

economic impacts associated with the 

conservation of the species, which may 

include some of the effects associated 

with listing. We note that the Act 

generally requires critical habitat to be 

designated at the time of listing, and if 

we had conducted an economic analysis 

at that time, the impacts associated with 

listing would not be readily 

distinguishable from those associated 

with critical habitat designation. 

35. Comment: The draft economic 

analysis first suggests that the costs 

arising from the potential loss of 

development opportunity on private 

lands in Benton County will be borne by 

the existing landowners, and then 

suggests that the acquisition of 

conservation easements under the 

Benton County Habitat Conservation 

Plan (HCP) will be borne by the County 

(i.e., public). 

Our Response: Private owners of 

critical habitat in Benton County could 

sell the development opportunity (i.e., 

conservation easement) on their land to 

the County if their land is a desired 

acquisition identified in the HCP. Under 

this scenario, the development impact 

would be to the public, because the 

development opportunity would be 

purchased from the private landowner 

with public funds. The conclusions in 

final economic analysis will be 

corrected. 

36. Comment: The economic costs in 

the draft economic analysis are 

overstated because the critical habitat 

designation is assumed to result in a 

complete loss of all development 

potential for all private lands within the 

critical habitat designation, even though 

there are no direct regulatory impacts on 

privately owned lands within the 

critical habitat designation. Further, the 

draft economic analysis does not 

consider wetland and rural zoning 

constraints that already limit 

development. Most of the privately 

owned critical habitat is located outside 

the urban growth boundaries (UGBs) 

and would not be developed within the 

20 year scope of the draft economic 

analysis. 

Our Response: As described in 

Section 4.0, Federal regulations do not 

usually constrain development on 

private lands, and Federal endangered 

species laws generally do not apply to 

listed plants on private lands. However, 

much of the Lupinus sulphureus ssp. 

kincaidii and Erigeron decumbens var. 

decumbens habitat overlaps with 

Fender’s blue butterfly habitat, is 

classified as wet prairie grassland 

habitat (E. decumbens var. decumbens), 

or occurs within the boundaries of the 

future Benton County HCP. In these 

situations, privately owned Fender’s 

blue butterfly, L. sulphureus ssp. 

Kincaidii, and E. decumbens var. 

decumbens habitat will have some level 

of protection through conservation 

actions included in an incidental take 

permit for Fender’s blue butterfly, 

recommended through a section 7 

consultation for a section 404 permit, or 

built into an HCP. Considering the 

absence of specific information on how 

development projects would mitigate for 

impacts to the species, the extent to 

which a future development project 

would be impacted by the species and 

habitat conservation is uncertain. The 

draft economic analysis presents the 

value derived from the option for future 

development of private lands, and 

explains that estimated impacts are 

overstated in the case that development 

is not constrained within the proposed 

critical habitat designation. Embedded 

in land values is the likelihood and 

timing of potential future development; 

that is, a parcel of land unlikely to be 

developed within the next 20 years 

would have a lower option value for 

development than an imminently 

developable parcel. The likelihood and 

timing of development is therefore 

incorporated into this analysis. The 

analysis further explains that the cost of 

development restrictions can be 

calculated proportionally for a unit if 

development is prohibited on only a 

portion of the unit. 

While wetland classification and rural 

zoning may limit development, they 

will not preclude it now or in the future. 

As described in the ‘‘Example of 

Potential Development Impacts’’ text 

box in Section 4.0, major development 

projects are being proposed on Erigeron 

decumbens var. decumbens wet prairie 

habitat, subject to compensatory 

mitigation. It is true that much of the 

privately owned land located outside 

the UGB may not be developed during 

the 20-year scope of the analysis, and 

that if it were developed it would be 

subject to the rural zoning regulations. 

However, the current zoning and future 

timing of development of each parcel of 

private land is not relevant to the 

economic analysis, because the 

economic impacts to private landowners 

will occur immediately after the lands 

are designated. Once announced, the 

critical habitat designation would 

impact the future development 

opportunity of a parcel for as long as the 

regulation is in place, even if the 

property is rural and located outside an 

UGB. Thus, while the actual 

development of a property may not 

occur within the 20-year scope of 

analysis, the impact to the private 

landowner from the critical habitat 

designation will occur the day the 

designation is announced, and therefore 

is appropriately measured in the draft 

economic analysis. 

37. Comment: If critical habitat 

designation limits the development 

opportunity of privately owned land, as 

presented in the draft economic 

analysis, the analysis should evaluate 

likely price increases on the remaining 

developable land within the region, 

because a reduction in the supply of 

developable land will cause the price of 

the remaining developable land to 

increase. 

Our Response: The impact of the loss 

in development opportunity on the 

remaining privately owned developable 

land, within the critical habitat 

designation is expected to be small, 

because the area impacted is relatively 

small compared to the supply of 

developable land in the region. As 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63871 

explained in Section 4.1 of the draft 

economic analysis, most of the future 

urban and rural development is 

projected to occur predominately on 

lands used for agriculture. The privately 

owned portion of the designation 

(approximately 2,100 acres) represents 

one-tenth of one percent of the 

agricultural acres in the eight county 

area (approximately 2 million acres). 

38. Comment: The proposed West 

Eugene Parkway (WEP), as designed 

prior to the critical habitat designation, 

was not an at-grade highway as 

described in the draft economic 

analysis, but rather an elevated 

highway. Therefore, the cost of species 

conservation activities presented in the 

draft economic analysis is in question. 

Our Response: The comment is 

correct. According to Oregon 

Department of Transportation (ODOT), 

the proposed project design is for an 

elevated structure. However, the 

proposed critical habitat designation 

caused ODOT to look more closely at 

the elevation, placement of supports, 

and length of elevated section. Because 

of the proposed critical habitat 

designation, the elevation of the 

proposed project is now higher and the 

length of the elevated section longer. 

While Section 6.1.2.1 incorrectly 

described the pre-critical habitat 

designation project as an at-grade 

roadway, the cost estimate provided by 

ODOT for the draft economic analysis 

correctly reflects the best estimate of 

additional costs associated with 

reconfiguring the elevated section 

spanning the proposed designation (i.e., 

higher and longer) to off-set impacts to 

the species. The final economic analysis 

will be corrected. 

39. Comment: The WEP is unlikely to 

be built anytime in the near future, and 

it should be considered speculative 

until the project is approved in a Record 

of Decision (ROD) and survives 

numerous legal and financial obstacles 

and political hurdles. Because the 

project is only speculative at this time, 

it should be excluded from the draft 

economic analysis. 

Our Response: As described in 

Section 1.3, the draft economic analysis 

estimates impacts based on activities 

that are ‘‘reasonably foreseeable,’’

including, but not limited to, activities 

that are currently authorized, permitted, 

or funded, or for which proposed plans 

are currently available to the public. 

The WEP falls under this latter category. 

While it is not known when WEP will 

ultimately be constructed, WEP is a 

proposed project that is the product of 

more than 20 years of planning, public 

involvement, environmental analysis, 

and engineering, and the goal is to 

complete the NEPA process with a 

signed ROD by the end of 2006 (Section 

6.1.2.1). Because the timing of the 

project is unknown (it will commence 

no earlier than 2008 based on 

anticipated dates for environmental 

compliance and permitting), the project 

is assigned an equal probability of 

occurring between years 2008 and 2026 

to reflect the uncertainty. 

40. Comment: The draft economic 

analysis does not consider benefits of 

critical habitat designation, including 

social welfare, input to regional 

economics, conservation bank revenues, 

recreation/educational/cultural benefits, 

support of local agriculture industry and 

jobs, land input for recreational values, 

and support of local tourism industry. 

Our Response: Where data are 

available, the analysis attempts to 

recognize and measure the net economic 

impact of the proposed designation. For 

example, as described in Section 7.2.3, 

145,000 people visit the Baskett Slough 

National Wildlife Refuge annually, 

primarily to hike and observe wildlife. 

While the visitor data are not broken 

down by species, and the annual 

number of individuals that visit the 

Refuge specifically to see Fender’s blue 

butterfly and Erigeron decumbens var. 

decumbens is not known, at least 300 

elementary school students and teachers 

visit the Refuge annually to observe 

Fender’s blue butterfly. The use 

demonstrates educational, cultural, and 

recreational benefits related to wildlife 

viewing. However, the Refuge does not 

charge for the school program, and there 

are no willingness-to-pay values specific 

to the species. Therefore, the analysis 

acknowledges the educational, cultural, 

and recreational benefits that the Refuge 

provides, but does not quantify 

associated welfare benefits. 

41. Comment: Economic benefits 

should be better quantified in the 

economic analysis, specifically the 

benefits associated with existence value, 

private land value increases due to 

supply constraints, farm and forest 

values of undeveloped lands, use values 

of natural lands, option values, amenity 

values of natural open spaces, ecological 

values, environmental quality, and 

social health and welfare. 

Our Response: Section 4(b)(2) of the 

Act requires the Secretary to designate 

critical habitat based on the best 

scientific data available after taking into 

consideration the economic impact, 

impact on national security, and any 

other relevant impact, of specifying any 

particular area as critical habitat. Our 

approach for estimating economic 

impacts includes both economic 

efficiency and distributional effects. The 

measurement of economic efficiency is 

based on the concept of opportunity 

costs, which reflect the value of goods 

and services foregone in order to 

comply with the effects of the 

designation (e.g., lost economic 

opportunity associated with restrictions 

on land use). When data are available, 

we attempt to measure the net economic 

impact in our economic analyses. 

However, no data was found that allows 

the measurement of such an impact, nor 

was information submitted during the 

public comment period. 

Most of the other benefit categories 

submitted reflect broader social values, 

which are not the same as economic 

impacts. While the Secretary must 

consider economic and other relevant 

impacts as part of the final decisionmaking process under section 4(b)(2) of 

the Act, the Act explicitly states that it 

is the government’s policy to conserve 

all threatened and endangered species 

and the ecosystems upon which they 

depend. Thus, we believe that explicit 

consideration of broader social values 

for these species and their habitats, 

beyond the more traditionally defined 

economic impacts, is not necessary 

because Congress has already clarified 

the social importance. As a practical 

matter, it is difficult to develop credible 

estimates of such values, because they 

are not readily observed through typical 

market transactions and can only be 

inferred through advanced, tailor-made 

studies that are time consuming and 

expensive to conduct. 

42. Comment: The cost estimates in 

the draft economic analysis fail to 

consider the cumulative effect of 

regulations on private lands. 

Our Response: We are required to 

consider only the effect of the proposed 

government action, which in this case is 

the designation of critical habitat for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens. The 

appropriate baseline for use in the 

economic analysis is the regulatory 

environment without this regulation. 

Against this baseline, we attempt to 

identify and measure the incremental 

costs and benefits associated with the 

designation of critical habitat. When 

critical habitat for other species has 

already been designated, it is properly 

considered part of the baseline for this 

analysis. Future critical habitat 

designations for other species in the 

area will be part of separate 

rulemakings, and consequently, their 

economic effects will be considered 

separately. 

43. Comment: The draft economic 

analysis includes costs that are 

independent of and unrelated to the 

listing or critical habitat designation, 


rwilkins on PROD1PC63 with RULES_2
63872 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

particularly costs related to maintaining 

the Baskett Slough National Wildlife 

Refuge and the West Eugene Wetlands 

restoration program. The proposed 

critical habitat is an overlay on 

previously delineated resources, and 

city and county ordinances and zoning, 

that are not considered in the draft 

economic analysis, resulting in an 

underestimation of actual costs; the 

draft economic analysis does not 

estimate the cumulative effects of 

regulation on private ownership. 

Our Response: As described in 

Section 1.2 of the draft economic 

analysis, coextensive effects as 

quantified in the draft economic 

analysis may also include impacts 

associated with overlapping protective 

measures of other Federal, State, and 

local laws and programs that aid habitat 

conservation in the areas proposed for 

designation. The draft economic 

analysis notes that in the past, some 

measures have been precipitated by the 

listing of the species and impending 

designation of critical habitat. Habitat 

conservation actions protecting a listed 

species are likely to contribute to the 

efficacy of critical habitat designations. 

Therefore, the impacts of them are 

considered relevant for understanding 

the full effect of the proposed critical 

habitat designation. Further, 

considering the absence of specific 

information on how development 

projects on private land would mitigate 

impacts to the species, the extent to 

which a future development project 

would be impacted by the species and 

habitat conservation is uncertain. The 

draft economic analysis therefore 

presents the value derived from 

potential future development on private 

lands (i.e., the complete loss of any and 

all development potential) and explains 

that estimated impacts would be 

overstated if development occurs within 

the proposed critical habitat 

designation. Any city, county, or other 

ordinance or regulation, such as 

wetland classification and rural zoning, 

may limit development, but not 

preclude it now or in the future (see 

‘‘Example of Potential Development 

Impacts’’ text box in Section 4.0). Thus, 

the economic impact of restrictions to 

the private landowner is already 

captured in the estimation of complete 

loss of any and all development 

potential. Enforcement actions taken in 

response to violations of the Act, 

however, are not included. 

44. Comment: The cost estimates are 

inadequate because of the extreme range 

of costs presented in the draft economic 

analysis. 

Our Response: To account for the 

range of land values, the variety of 

mitigation measures available for offsetting impacts, and the uncertain 

timing and cost of project mitigation, 

the analysis presents the potential costs 

associated with species conservation 

actions as a range. 

45. Comment: The draft economic 

analysis recognizes the potential for 

additional economic impacts under 

other state or local laws triggered by 

critical habitat designation. Yet, the 

economic analysis does not consider the 

efforts recently begun by the City of 

Eugene to inventory upland prairie and 

other habitats under Goal 5, which will 

be the basis of future recommendations 

on possible protection measures or 

conservation incentive programs. 

Our Response: This is correct; the 

draft economic analysis does not 

specifically consider the City’s 

inventory program. As stated by the 

commenter, this is goal oriented and it 

is uncertain what this inventory means 

in terms of future regulatory costs. 

Summary of Changes From Proposed 

Rule 

The area proposed as critical habitat 

in Eugene, Oregon, for the Fender’s blue 

butterfly has been revised for this final 

designation. Specifically, the areas that 

were proposed as a corridor between 

stepping-stone areas and core 

populations are not included in this 

final designation. We re-evaluated these 

areas and determined that they do not 

provide features essential to the 

conservation of the Fender’s blue 

butterfly. Specifically, the corridor is 

largely a channel of water, delineated 

bank to bank, which does not include 

prairie habitat. Furthermore, Schultz 

(1998, p. 291) documented that 

stepping-stones would be more 

beneficial to the butterfly than corridors, 

and McIntire et al. (2006, in review, p. 

20–22) identified specific butterfly 

stepping-stone habitat in the Eugene, 

Oregon, area necessary to re-establish a 

connected, functioning network of 

habitat. Areas specifically identified in 

McIntire et al. (2006, in review, p. 20–

22) were included in the proposed rule 

and remain in this final designation, 

with the exception of one steppingstone area (0.4 ac (0.2 ha)) that was 

overlooked as a result of a mapping 

error in the proposed designation. 

During the initial comment period for 

the proposed critical habitat 

designation, we received new 

information about two of the Lupinus 

sulphureus ssp. kincaidii units and one 

of the Fender’s blue butterfly units. This 

information indicated that KL–8, KL–

16B, and FBB–7 units included areas 

that do not provide the features 

essential to the conservation of these 

species. Therefore, we reduced KL–8 

and FBB–7 to include only areas 

containing the features essential to the 

conservation of the species. Unit KL–

16B was eliminated because it lacks 

appropriate features. 

Based on comments from peer 

reviewers, we made minor 

modifications to the primary consitutent 

elements for all three species. In the first 

primary consitutent elements for the 

Fender’s blue butterfly and Erigeron 

decumbens var. decumbens, we 

clarified that both upland and wet 

prairie habitat are features essential to 

the conservation of the species. For 

Lupinus sulphureus ssp. kincaidii and 

E. decumbens var. decumbens, we 

removed references from the first 

primary consitutent elements that gave 

a greater level of importance to proper 

moisture and protection from 

competitive invasive species than is 

essential. 

In the proposed rule, the first Fender’s 

blue butterfly primary consitutent 

element was as follows: 

(1) Early seral upland prairie, oak 

savanna habitat with undisturbed 

subsoils that provides a mosaic of lowgrowing grasses and forbs, and an 

absence of dense canopy vegetation 

allowing access to sunlight needed to 

seek nectar and search for mates; 

In this final rule, the first PCE is as 

follows: 

(1) Early seral upland prairie, wet 

prairie, or oak savanna habitat with a 

mosaic of low-growing grasses and 

forbs, an absence of dense canopy 

vegetation; and undisturbed subsoils. 

In the proposed rule, the first primary 

consitutent element for Lupinus 

sulphureus ssp. kincaidii was as 

follows: 

(1) Early seral upland prairie, oak 

savanna habitat with a mosaic of lowgrowing grasses, forbs, and spaces to 

establish seedlings or new vegetative 

growth, with an absence of dense 

canopy vegetation providing sunlight 

for individual and population growth 

and reproduction and with undisturbed 

subsoils and proper moisture and 

protection from competitive invasive 

species.

Based on the information provided by 

several peer reviewers, we made minor 

corrections throughout the document to 

reflect the most accurate representation 

of the best available scientific 

information, including revisions to the 

methodology section to more accurately 

describe the methodology used for the 

proposed designation. The unit 

descriptions were also updated to more 

accurately identify areas included 

within the final designation. 

Critical Habitat 

Critical habitat is defined in section 3 

of the Act as—(i) the specific areas 

within the geographical area occupied 

by a species, at the time it is listed in 

accordance with the Act, on which are 

found those physical or biological 

features (I) essential to the conservation 

of the species and (II) that may require 

special management considerations or 

protection; and (ii) specific areas 

outside the geographical area occupied 

by a species at the time it is listed, upon 

a determination that such areas are 

essential for the conservation of the 

species. Conservation, as defined under 

section 3 of the Act, means to use and 

the use of all methods and procedures 

necessary to bring any endangered 

species or threatened species to the 

point at which the measures provided 

pursuant to the Act are no longer 

necessary. Such methods and 

procedures include, but are not limited 

to, all activities associated with 

scientific resources management such as 

research, census, law enforcement, 

habitat acquisition and maintenance, 

propagation, live trapping, and 

transplantation, and, in the 

extraordinary case where population 

pressures within a given ecosystem 

cannot be otherwise relieved, regulated 

taking. 

Critical habitat receives protection 

under section 7 of the Act through the 

prohibition against destruction or 

adverse modification of critical habitat 

with regard to actions carried out, 

funded, or authorized by a Federal 

agency. Section 7 requires consultation 

on Federal actions that are likely to 

result in the destruction or adverse 

modification of critical habitat. The 

designation of critical habitat does not 

affect land ownership or establish a 

refuge, wilderness, reserve, preserve, or 

other conservation area. Such 

designation does not allow government 

or public access to private lands. 

Section 7 is a purely protective measure 

and does not require implementation of 

restoration, recovery, or enhancement 

measures. 

To be included in a critical habitat 

designation, the habitat within the area 

occupied by the species must first have 

features that are essential to the 

conservation of the species. Critical 

habitat designations identify, to the 

extent known using the best scientific 

data available, habitat areas that provide 

essential life cycle needs of the species 

(i.e., areas on which are found the 

primary constituent elements, as 

defined at 50 CFR 424.12(b)). 

Habitat occupied at the time of listing 

may be included in critical habitat only 

if the essential features thereon may 

require special management or 

protection. Thus, we do not include 

areas where existing management is 

sufficient to conserve the species. (As 

discussed below, such areas may also be 

excluded from critical habitat pursuant 

to section 4(b)(2).) Accordingly, when 

the best available scientific data do not 

demonstrate that the conservation needs 

of the species require additional areas, 

we will not designate critical habitat in 

areas outside the geographical area 

occupied by the species at the time of 

listing. An area currently occupied by 

the species but not known to be 

occupied at the time of listing will 

likely, but not always, be essential to the 

conservation of the species, and 

therefore, typically included in the 

critical habitat designation. 

The Service’s Policy on Information 

Standards Under the Endangered 

Species Act, published in the Federal 

Register on July 1, 1994 (59 FR 34271), 

along with Section 515 of the Treasury 

and General Government 

Appropriations Act for Fiscal Year 2001 

(Pub. L. 106–554; H.R. 5658) and the 

associated Information Quality 

Guidelines issued by the Service, 

provide criteria and guidance and 

establish procedures to ensure that 

decisions made by the Service represent 

the best scientific data available. They 

require Service biologists, to the extent 

consistent with the Act and with the use 

of the best scientific data available, to 

use primary and original sources of 

information as the basis for 

recommendations to designate critical 

habitat. When determining which areas 

are critical habitat, the Service generally 

uses the listing package as a primary 

source of information. Additional 

information sources include articles in 

peer-reviewed journals, conservation 

plans developed by States and counties, 

scientific status surveys and studies, 

biological assessments, or other 

unpublished materials and expert 

opinion or personal knowledge. All 

information is used in accordance with 

the provisions of Section 515 of the 

Treasury and General Government 

Appropriations Act for Fiscal Year 2001 

(Pub. L. 106–554; H.R. 5658) and the 

associated Information Quality 

Guidelines issued by the Service. 

Section 4 of the Act requires that we 

designate critical habitat on the basis of 

the best scientific data available. Habitat 

is often dynamic, and species may move 

from one area to another over time. 

Furthermore, we recognize that 

designation of critical habitat may not 

include all of the habitat areas that may 

eventually be determined to be 

necessary for the recovery of the 

species. For these reasons, critical 

habitat designations do not signal that 

habitat outside the designation is 

unimportant or not required for 

recovery. It is generally understood that 

recovery of remaining populations will 

involve expanding existing populations, 

increasing connectivity, and/or 

improving habitat quality (Schultz et al. 

2003, pp. 61, 68–70; Severns 2003a, p. 

227; Wilson et al. 2003, pp. 79–80). 

Most populations of Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

Kincaidii, and Erigeron decumbens var. 

decumbens have not been studied well 

enough to determine how to restore 

functioning metapopulations in these 

highly fragmented prairie remnants. 

Because each of the remaining 

populations occurs in a unique habitat 

setting, habitat analyses will likely need 

to be completed to determine which 

lands are suitable for expanding 

populations, increasing connectivity, 

and reestablishing functioning 

metapopulations. McIntire et al. (in 

review, p. 2) demonstrate the usefulness 

of utilizing a focal species approach and 

spatially explicit models in planning 

restoration activities for at-risk species 

such as the Fender’s blue butterfly. 

However, this approach to developing 

restoration options for conserving at-risk 

species requires an understanding of 

potentially suitable habitat within the 

constraints of a unique habitat setting 

(McIntire et al. in review, p. 3). For 

many populations of Fender’s blue 

butterfly, L. sulphureus ssp. kincaidii, 


rwilkins on PROD1PC63 with RULES_2
63874 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

and E. decumbens var. decumbens, we 

do not have the information necessary 

to specifically identify additional areas 

that may be suitable for restoration and 

useful for increasing connectivity 

between populations and larger 

metapopulations. 

Areas that support populations, but 

are outside the critical habitat 

designation, will continue to be subject 

to conservation actions implemented 

under section 7(a)(1) of the Act, and to 

the regulatory protections afforded by 

the section 7(a)(2) jeopardy standard, as 

determined on the basis of the best 

available information at the time of the 

action. Federally funded or permitted 

projects affecting listed species outside 

their designated critical habitat areas 

may still result in jeopardy findings in 

some cases. Similarly, critical habitat 

designations made on the basis of the 

best available information at the time of 

designation will not control the 

direction and substance of future 

recovery plans, habitat conservation 

plans, or other species conservation 

planning efforts if new information 

available to these planning efforts calls 

for a different strategy. 

Primary Constituent Elements 

In accordance with section 3(5)(A)(i) 

of the Act and regulations at 50 CFR 

424.12, in determining which areas to 

designate as critical habitat, we consider 

those physical and biological features 

(primary constituent elements (PCEs)) 

that are essential to the conservation of 

the species, and within areas occupied 

by the species at the time of listing, that 

may require special management 

considerations and protection. These 

include, but are not limited to, space for 

individual and population growth and 

for normal behavior; food, water, air, 

light, minerals, or other nutritional or 

physiological requirements; cover or 

shelter; sites for breeding, reproduction, 

and rearing (or development) of 

offspring; and habitats that are protected 

from disturbance or are representative of 

the historic geographical and ecological 

distributions of a species. 

The specific primary constituent 

elements required for the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens are derived from the 

biological needs of these species as 

described in the Background section of 

this proposal. 

Space for Individual and Population 

Growth and Normal Behavior 

Fender’s blue butterfly 

Historically, the Willamette Valley 

was a mosaic of upland and wetland 

prairie, with lupine patches rarely more 

than 0.3 miles (0.5 km) apart, providing 

a high probability that the Fender’s blue 

butterfly could disperse between 

patches (Schultz 1998, p. 284). Habitat 

fragmentation has isolated the 

remaining populations of Fender’s blue 

butterfly to such an extent that dispersal 

between suitable habitat patches is now 

likely a rare event (Schultz 1998, p. 

291), which increases the risk of 

inbreeding depression (Schultz et al. 

2003, p. 70). The rarity of host lupine 

patches and habitat fragmentation are 

the major ecological factors limiting 

reproduction, dispersal, and subsequent 

colonization of new habitat (Hammond 

and Wilson 1992, p. 172; Schultz 1997a, 

p. 88; Schultz and Dlugosch 1999, p. 

231). 

Conservation recommendations for 

recovering the Fender’s blue butterfly 

include having enough high-quality 

habitat to maintain viable populations 

across the range of the species (Schultz 

et al. 2003, p. 61, 68). This will require 

habitat restoration to create new sites, 

expanding the size of existing sites, and 

creating habitat networks that connect 

isolated populations (Schultz et al. 

2003, p. 68, 69–70). By comparing field 

notes (USFWS 2004a, entire data set) to 

population counts (Fitzpatrick 2005, pp. 

10, 11; Hammond 2004, p. 35), we 

determined that the largest remaining 

Fender’s blue butterfly populations 

generally occur in the largest, most 

connected prairie remnants currently 

supporting the species. Although the 

prairie habitat supporting these 

populations is threatened to varying 

degrees by invasive species and woody 

succession, it also appears to have the 

highest diversity of native plant species. 

Large habitat patches tend to support 

higher native species diversity (Noss 

and Cooperrider 1994, p. 34) and the 

Fender’s blue butterfly depends on a 

diversity of native plant species for 

survival (Wilson et al. 1997, p. 3, 5). 

To promote successful dispersal 

among lupine patches and reestablish 

functioning metapopulations, Fender’s 

blue butterflies will likely require 

stepping stones of lupine patches that 

are close enough together for dispersing 

butterflies to have a high probability of 

finding the patches (Schultz 1998, p. 

284, 286). This conservation reserve 

strategy is superior to narrow linear 

corridors because the Fender’s blue 

butterfly flight patterns into non-lupine 

habitat make it unlikely they would stay 

in a narrow corridor (Schultz 1998, p. 

284, 286, 291). Reestablishing stepping 

stones of lupine habitat between 

existing populations increases the 

likelihood that dispersing individuals 

will move from one large lupine patch 

to the next (Schultz 1998, p. 291). 

Lupine patches should be less than 0.6 

mile (1 km) from their nearest neighbor 

(Schultz 1998, p. 291; Schultz 2001, p. 

1008; Schultz and Crone 2005, p. 887, 

892) to restore functioning 

metapopulations for the Fender’s blue 

butterfly and ensure the long-term 

persistence of this species (Schultz et al. 

2003, p. 70). 

For the conservation of the Fender’s 

blue butterfly we anticipate we will 

need several functioning habitat 

networks distributed across the range of 

the species. Connectivity will be best 

achieved among the component 

butterfly subpopulations by a steppingstone arrangement of sites that meet 

minimum size, distance, and quality 

criteria. 

Lupinus sulphureus ssp. kincaidii 

For many organisms that are patchily 

distributed, the minimum viable 

population will often depend on both 

the occupied and surrounding 

unoccupied habitat that is protected and 

managed for the species (Nunny and 

Campbell 1993, p. 238). Plant 

populations often occupy only small 

regions of the available habitat at any 

one period, and this pattern is relevant 

to their conservation (Menges 1991, pp. 

53, 54). The habitat between plant 

patches may serve as a site for future 

populations and may be critical for the 

long-term perseverance of the species 

(Nunny and Campbell 1993, p. 238). 

Wilson (1998b, p. 2) has documented 

that the open spaces between 

bunchgrasses in prairie habitat are often 

utilized for seedling establishment and 

the vegetative spread of forbs. 

Native upland prairies are lowgrowing plant communities dominated 

by bunchgrasses with open spaces 

occurring between plants (Wilson 

1998b, p. 2). Spaces between 

bunchgrasses remain available for the 

vegetative spread of lupine and seedling 

establishment necessary for expanding 

population size and increasing 

population viability. Severns (in review, 

p. 10) documents that Lupinus 

sulphureus ssp. kincaidii natural 

germinants were found primarily 

growing in habitats with exposure to 

sunlight such as areas of bare ground 

and short grasses. In addition to 

providing space for population growth, 

larger prairie habitats provide 

opportunity for population expansion 

because the native grasses and forbs 

maintain the short-grass prairie stature 

and provide the full-sun conditions 

necessary for the species to grow and 

expand into surrounding habitat 

(Wilson 1998b, p. 2).

Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63875 

Lupinus sulphureus ssp. kincaidii 

populations exhibit typical signs of 

inbreeding depression (a process that 

weakens plant fitness through repeated 

generations of inbreeding) such as low 

seed production, which is attributed to 

the small size and isolated nature of the 

species’ current distribution (Severns 

2003a, p. 221, 222; Wilson et al. 2003, 

p. 75). Insect outcrossing pollination 

(the transfer of pollen from the flower of 

one plant to the flower of another plant 

of the same species) has been 

documented as important for the 

conservation of L. sulphureus ssp. 

kincaidii (Wilson et al. 2003, p. 72, 75). 

Since L. sulphureus ssp. kincaidii is a 

long-lived perennial that can grow 

wider than 10 m across, and 

observations suggest that lupine patches 

are either one individual or a few 

closely related individuals (Severns 

2003a, p. 225), successful outcrossing 

pollination will require large 

populations with many individuals or 

multiple plant patches of unrelated 

individuals that are functionally 

connected (i.e., they are in close enough 

proximity that pollinators will move 

between the patches). The number of L. 

sulphureus ssp. kincaidii patches 

occurring within a prairie remnant has 

been positively correlated with 

increased seed production, likely 

because larger populations have a 

higher density of floral displays and 

attract more pollinators (Severns 2003a, 

pp. 221, 222, 225). Since population 

size is important for visibility to 

pollinators and the successful 

reproduction of L. sulphureus ssp. 

kincaidii, increasing the size of existing 

populations will play a role in 

recovering this species (Severns 2003a, 

p. 226). 

Habitat management for the 

conservation of Lupinus sulphureus ssp. 

kincaidii should include expanding the 

size of existing populations by 

augmenting them with individuals from 

other populations (Severns 2003a, p. 

227). The prairie habitat occurring 

between existing lupine patches is 

necessary to provide space for 

augmentations intended to reduce the 

effects of inbreeding depression. 

Smaller distances between plant patches 

increase the likelihood of outcrossing as 

insect pollinators more readily travel 

among nearby patches to transfer pollen 

between individual plants. Therefore, 

the stepping-stone reserve design 

recommended for the Fender’s blue 

butterfly will also benefit L. sulphureus 

ssp. kincaidii by increasing opportunity 

for pollen transfer between existing 

plant patches and allowing current 

small populations to function together 

as larger ones (Severns 2003a, p. 227). 

The Lupinus sulphureus ssp. kincaidii 

will benefit from conserved habitat 

across the historic range of the species, 

with populations larger than 0.25 ac (0.1 

ha) of lupine cover and within 5 miles 

(8 km) of neighboring populations 

(Gisler et al., in litt., 2005, pp. 6, 7). An 

area-based measurement is used for 

minimum patch size due to the 

difficulty of counting individual plants 

of this clonal species. The 5-mile (8-km) 

criterion is based on the maximum 

pollinating distance of the honeybee 

(Apis mellifera) (Beekman and Ratnieks 

2000, p. 493; Steffan Dewenter and 

Kuhn 2003, p. 571), which is the 

pollinator with the greatest travel 

distance for L. sulphureus ssp. kincaidii 

(Gisler et al., in litt., 2005, p. 7). These 

criteria are expected to promote larger 

functioning metapopulations, with 

increased population sizes and genetic 

diversity, which in turn promote longterm population viability and species 

conservation. 

Erigeron decumbens var. decumbens 

Erigeron decumbens var. decumbens 

populations are currently vulnerable to 

inbreeding depression throughout their 

range because they occur in small, 

isolated habitat patches (Jackson 1996, 

p. 88). Jackson (1996, p. 28) documents 

that conservation plans for the wet 

prairie habitat must emphasize 

connections, corridors, and large areas 

of contiguous habitat. Clark et al. (1993, 

p. 44) identified habitats critical for the 

conservation of E. decumbens var. 

decumbens and recommends protecting 

sites harboring large populations of 

native plants, prairie habitat providing 

physical links between E. decumbens 

var. decumbens populations, and 

potential sites for restoration in order to 

reduce the current threats to survival. 

Erigeron decumbens var. decumbens 

populations are typically distributed in 

clumps scattered across the prairie 

habitat and dispersed among other 

prairie indicator species (Clark et al. 

1993, pp. 21, 22). Larger prairie 

remnants are more likely to provide the 

conditions necessary to support 

population growth because the native 

species composition maintains the light 

and open spaces between bunch grasses 

necessary for this species to persist and 

expand. Conservation measures 

necessary for maintaining and 

increasing the few remaining 

populations of E. decumbens var. 

decumbens include promoting 

conditions for natural regeneration and 

possibly augmenting small populations 

with propagated individuals (Clark et al. 

1995b, p. 22). Open spaces between 

bunch grasses allow E. decumbens var. 

decumbens to establish seedlings and 

vegetatively spread within a habitat 

patch. Larger prairie remnants provide 

the area necessary for planting 

propagated individuals and for natural 

regeneration. 

Food 

The Fender’s blue butterfly uses 

Lupinus sulphureus ssp. kincaidii, L. 

arbustus (spurred lupine), and L. 

albicaulis (sickle-keeled lupine) as 

larval host plants. Adult Fender’s blue 

butterflies require several forbs for 

nectar (Schultz and Dlugosch 1999, p. 

232; Schultz et al. 2003, p. 65). 

Examples of adult nectar sources 

include: Allium acuminatum (tapertip 

onion), Allium amplectans (narrowleaf 

onion), Calochortus tolmiei (Tolmie’s 

mariposa lily), Eriophyllum lanatum 

(woolly sunflower), Sidalcea campestris 

(Meadow checkermallow), Sidalcea 

virgata (rose checker-mallow), Vicia 

sativa (common vetch), and V. hirsuta 

(tiny vetch) (Kaye in litt.a, p. 2) These 

exotic vetches (V. sativa and V. hirsuta) 

are heavily used at many sites but are 

considered a lower quality source of 

nectar (Schultz et al. 2003, p. 65). 

Light 

As previously described, all three 

species are early seral and occur in open 

areas. Willamette Valley grasslands have 

been described as a mixture of wet and 

upland prairie habitat and oak/savanna 

habitat having a relatively open canopy 

cover (Altman et al. 2001, p. 261). These 

open areas were historically maintained 

by indigenous people who seasonally 

burned the land to facilitate hunting and 

gathering of food (Clark 2000, p. 3; 

Jackson 1996, pp. 11, 12). The fires 

prevented the widespread abundance of 

woody species and maintained the 

openness needed for early seral species 

to persist (Jackson 1996, p. 1; Wilson et 

al. 2003, p. 79). Change in this historic 

disturbance regime has allowed shrubs 

and trees to invade many prairies and 

oak/savannas. 

Populations of Fender’s blue butterfly 

and Lupinus sulphureus ssp. kincaidii 

historically occurring in the oak/ 

savannas were probably the first to be 

lost to succession and development. 

Most of the remaining populations were 

found in the valley floor prairies. 

Lupinus sulphureus ssp. kincaidii and 

many of the Fender’s blue butterfly 

nectar sources do not tolerate decreases 

in available light resulting from dense 

canopy closure as prairies gradually 

grow into woodlands in the absence of 

disturbance (Schultz et al. 2003, p. 69). 

Erigeron decumbens var. decumbens 

typically occurs where woody cover is 


rwilkins on PROD1PC63 with RULES_2
63876 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

nearly absent and where herbaceous 

vegetation cover is low in stature 

relative to the surrounding areas (Clark 

et al. 1993, p. 22). 

Native Willamette Valley prairies are 

predominantly low-stature communities 

with most plant foliage occurring within 

8 inches (20 cm) of the soil, but with 

flowering stalks of some of the grasses 

reaching up to 59 inches (150 cm) in 

height (Wilson 1998a, p. 2, 1998b, p. 2). 

Maintaining the stature of the prairie 

habitat that surrounds the patches of 

Lupinus sulphureus ssp. kincaidii and 

Erigeron decumbens var. decumbens is 

important for the conservation of these 

species. Lupinus sulphureus ssp. 

kincaidii seedlings are more numerous 

in shortgrass prairie habitat without tall 

competing vegetation (Severns in 

review, p. 9). Shading, whether by 

native or non-native vegetation, is likely 

to hamper L. sulphureus ssp. kincaidii 

seed germination and germinant 

survival, although reproducing plants 

may be able to persist in shaded 

conditions (Severns in review, p. 10, 

11). The shortgrass prairie stature is also 

important for the conservation of the 

Fender’s blue butterfly (Schultz et al. 

2003, p. 69). This butterfly is more 

vigorous in the full sun of open habitats, 

which provide conditions that promote 

nectaring and ovipositioning (Schultz et 

al. 2003, p. 68). 

As previously identified, populations 

of Lupinus sulphureus ssp. kincaidii 

occurring in Douglas County, Oregon, 

have been documented in atypical 

habitat for the species (Barnes 2004, p. 

95). The Douglas County populations 

are in wooded areas dominated by 

Pseudotsuga menziesii (Douglas-fir), 

Arbutus menziesii (Pacific madrone), 

and other trees and shrubs (Barnes 2004, 

p. 102) with canopy cover ranging from 

50 to 80 percent (Barnes 2004, p. 102). 

Because these populations represent the 

southern most extent of this species’

range, they may be adapted to tolerate 

more extreme habitat and/or other 

environmental conditions. 

Moisture 

Plant communities in prairie 

ecosystems mainly vary due to the 

differences in moisture attributed to 

elevation, slope, and soil permeability 

(Jackson 1996, p. 9). The Willamette 

Valley prairies have been categorized 

into two habitat types, wet prairie and 

upland prairie (Jackson 1996, p. 9). The 

wet prairie habitat is defined as areas of 

low relief, with poor drainage and 

hydric, clayey soils (Jackson 1996, p. 9), 

dominated by bunchgrasses, most 

predominately Deschampsia caespitosa 

(Clark et al. 1993, p. 18; Jackson 1996, 

pp. 9, 10). Jackson (1996, p. 9) describes 

the term ‘‘upland prairie’’ as misleading 

because the habitat largely occurs on the 

valley floor. A few upland prairie 

habitat patches occur on colluvium 

upland soils (i.e., poorly sorted debris 

that has accumulated at the base of 

slopes, in depressions, or along small 

streams through gravity, soil creep, and 

local wash (Jackson 1996, p. 10)), but 

many occur on soils not considered 

upland, such as terraces, alluvium, and 

even floodplain soils (Clark et al. 1993, 

p. 20; Jackson 1996, p. 10; Wilson et al. 

2003, p. 79). Although many of the 

habitat patches supporting the Fender’s 

Blue Butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens occur on the valley floor, 

they have been characterized as ‘‘upland 

prairies’’ because of their drier 

conditions, which are attributed to 

better draining soils or local variations 

in topography (Jackson 1996, p. 10). 

This upland prairie habitat is typically 

characterized by the vegetation that 

thrives in these well-drained conditions 

(associated species previously 

identified) (Jackson 1996, p. 10). 

Erigeron decumbens var. decumbens 

grows in both wet and upland prairies. 

The populations in wet prairies tend to 

occur in the driest portions of the wet 

prairie habitat. Erigeron decumbens var. 

decumbens grows in the driest habitats 

in which Deschampsia caespitosa can 

grow, but prefers slightly dryer 

microsites where D. caespitosa is sparse 

(Clark et al. 1993, p. 18). Lupinus 

sulphureus ssp. kincaidii populations 

occur predominately in upland prairie 

habitat with a few occurring in the 

transitional areas between wet and 

upland prairie habitats. The Fender’s 

blue butterfly largely occurs in upland 

prairies; however, several adult nectar 

sources occur in wet prairies and are 

utilized by the butterfly when wet 

prairie patches are adjacent to lupine 

patches. 

Reproduction 

Fender’s blue butterfly 

Adult Fender’s blue butterflies emerge 

in May and females lay their eggs on the 

underside of lupine leaves. The 

butterfly uses the following three lupine 

species as host plants for oviposition: 

Lupinus sulphureus ssp. kincaidii, L. 

arbustus, and L. albicaulis. A few weeks 

after oviposition, the eggs hatch and the 

larvae eat lupine leaves for a few weeks 

until the lupines senesce. After lupine 

senescence, the larvae enter an extended 

diapause that lasts until the following 

March. When the lupine plants 

resurface, the larvae emerge from the 

soil litter and begin eating the young 

lupine leaves until the larvae pupate in 

mid-April (Schultz et al. 2003, p. 64). 

Adult females likely lay up to 350 eggs 

(Schultz et al. 2003, pp. 66, 67) over 

their estimated 15-day lifespan. Based 

on survivorship information (Schultz 

and Crone 1998, p. 247; Schultz et al. 

2003, p. 67), we estimate that of the 350 

eggs, approximately 1.5 will survive to 

adulthood, indicating that Fender’s blue 

butterfly survivorship is very low. 

Native prairie composition, including 

short-stature grasses, provides the full 

sun conditions required for Lupinus 

sulphureus ssp. kincaidii plants to 

produce an abundance of leaves on 

which Fender’s blue butterfly lays eggs. 

Invasive species often cover the lupine 

leaves, making it difficult for the 

butterfly to oviposit. Native nectar 

sources are of higher quality than nonnative adult food sources, and butterfly 

populations dependent on low quality 

exotic vetches may spend more of their 

limited adult flight time nectaring, and 

less time ovipositioning (Schultz et al. 

2003, p. 65). 

Schultz and Crone (2001, pp. 1889–

1890) found that Fender’s blue butterfly 

population patterns are influenced by 

habitat patch size through residence 

time of female butterflies; butterflies 

emigrate from smaller patches more 

quickly than they do from larger 

patches. This directly influences the 

numbers and spatial distribution of 

eggs, and therefore the future number of 

butterflies. The tendency of the Fender’s 

blue butterfly to quickly disperse from 

small, isolated lupine patches increases 

the risk they won’t find another suitable 

oviposition site. This, in turn, reduces 

the total lifetime reproduction to well 

below the 350 egg maximum reported 

by Schultz et al. (2003, pp. 66, 67). 

Because Fender’s blue butterflies only 

live for approximately 2 weeks, a 

change in residence time of even 1 day 

may markedly influence the distribution 

of eggs. 

Lupinus sulphureus ssp. kincaidii 

Lupinus sulphureus ssp. kincaidii 

flowers possess a pump or piston 

arrangement for cross-pollination by 

insects, as is common in other lupines 

(Kaye 1999, p. 50). Pollination of L. 

sulphureus ssp. kincaidii appears to be 

carried out by bees visiting the flowers; 

the relatively small flowers attract only 

small bees (Wilson et al. 2003, p. 74). 

Several bee species have been 

documented commonly visiting L. 

sulphureus ssp. kincaidii flowers, such 

as small bumblebees (Bombus mixtus 

and B. californicus) and the European 

honey bee (Apis mellifera). As described 

in Wilson et al. (2003, p. 75), insect 

pollination appears to be critical for 

successful seed production in L. 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63877 

sulphureus ssp. kincaidii. The 

maturation of the flowers of L. 

sulphureus ssp. kincaidii promotes 

outcrossing pollination because of the 

way they mature from the bottom of the 

inflorescence to the top (Wilson et al. 

2003, p. 75). 

Inbreeding depression may limit the 

seed set and seed fitness of smaller 

lupine populations (Severns 2003a, p. 

225; Wilson et al. 2003, p. 75). 

Conserving Lupinus sulphureus ssp. 

kincaidii will likely require the 

outcrossing of populations by planting 

new individuals from different sources 

near existing populations, and 

increasing pollinator connectivity 

between existing populations (Severns 

2003a, p. 227). 

Erigeron decumbens var. decumbens 

This species spreads vegetatively via 

rhizomes over short distances (about 4 

inches (10 cm)) (Kaye 2000, p. 1) and 

the plants often grow in clumps, making 

it difficult to distinguish individuals. 

Sexual reproduction is facilitated by 

insect pollination. Pollinators include 

species such as the field crescent 

butterfly (Phyciodes campestris), sweat 

bees (Halictidae spp.), and a syrphid fly 

(Toxomerous occidentalis) (Jackson 

1996, p. 81). Seeds are dispersed by 

wind, but over very short distances 

(Clark et al. 1993, p. 33). Research 

indicates that scarification stimulates 

germination, but the mechanism for 

seed coat scarification (scoring of the 

seed coat) in the wild is unknown (Clark 

et al. 1995b, pp. 14–15). Germination of 

Erigeron decumbens var. decumbens 

seeds occurs mostly in April and May 

(Clark et al. 1997, p. 45) and flowering 

is concentrated in June and early July 

(Meinke 1982, p. 136). 

Jackson (1996, p. 2) reports that 

remaining populations of Erigeron 

decumbens var. decumbens may be 

experiencing reproductive difficulties 

because they are extremely small and 

isolated from one another. Gene flow 

between individuals of a sexuallyreproducing species is requisite for their 

persistence (Jackson 1996, pp. 2–3). 

Research results indicate that the E. 

decumbens var. decumbens is at risk of 

inbreeding depression (Jackson 1996, p. 

88). To reduce this risk and to conserve 

the species, it will likely be necessary to 

increase the number of habitat patches 

located in close proximity to one 

another such that functioning 

metapopulations are restored. This 

population arrangement increases the 

opportunities for insects to carry pollen 

between individual plants and increases 

the likelihood of reproductive success of 

E. decumbens var. decumbens. 

Areas Representative of the Historic 

Geographical and Ecological 

Distributions of a Species 

Fender’s blue butterfly 

Conservation recommendations for 

the Fender’s blue butterfly include 

having a reserve design with a 

minimum of two populations for each 

occupied county (eight total) so that a 

local back-up is always available in case 

of site extirpations (Hammond and 

Wilson 1993, p. 45). By maintaining 

viable metapopulations across the 

species’ range, the distribution would be 

wide enough to buffer the species from 

catastrophes that may occur in portions 

of its range (Schultz et al. 2003, p. 68). 

Recommendations for reserve design 

criteria for this species include 

preserving populations that occur under 

unique conditions, as distinct ecological 

segregates (Hammond and Wilson 1993, 

p. 45). Therefore, populations occurring 

in unique habitat conditions should be 

conserved across the range of the 

species. A few unique Fender’s blue 

butterfly populations occur on valley 

hillsides, such as Coburg Ridge, but the 

vast majority of remaining sites occur on 

the valley floor under different habitat 

conditions (Hammond and Wilson 1993, 

p. 45). The unique habitat supporting 

these valley hillside populations 

appears to be stable climax grasslands 

due to the presence of deep, finetextured, self-mulching soils or Ustic 

(very dry) lithosols (Franklin and 

Dyrness 1973, p. 119; Hammond 1994, 

p. 45). 

Lupinus sulphureus ssp. kincaidii 

Lupinus sulphureus ssp. kincaidii 

populations in Douglas County, Oregon 

and Lewis County, Washington, 

represent the furthest southern and 

northern extent of the current range, 

respectively. These populations are 

highly disjunct and isolated from the 

Willamette Valley populations with 

approximately 81 miles (131 km) 

between the northernmost Willamette 

Valley population to the Lewis County, 

Washington population, and 

approximately 54 miles (87 km) 

separating Oregon’s south Willamette 

Valley populations from the Douglas 

County populations. 

The primary habitat for Lupinus 

sulphureus ssp. kincaidii is open 

upland prairie and meadow edges, often 

near oak trees with a relatively open 

canopy cover. Most of the Douglas 

County, Oregon, populations appear to 

tolerate more shaded habitat conditions 

with canopy cover of 50 to 80 percent 

(Barnes 2004, p. 102). Because these 

populations represent the southern-most 

extent of this species’ range, they may 

be adapted to tolerate more extreme 

habitat or other environmental 

conditions. Therefore, conservation of L. 

sulphureus ssp. kincaidii populations 

across their current range will require 

conservation of areas in Lewis County, 

Washington and Douglas County, 

Oregon, in addition to areas in the 

Willamette Valley, Oregon (Gisler et al., 

in litt., 2005, pp. 3, 11; Robinson et al., 

in litt., 2005, pp. 2, 3). 

Erigeron decumbens var. decumbens 

Erigeron decumbens var. decumbens 

occurs on wetland prairie dominated by 

Deschampsia caespitosa. It also occurs 

on a few upland prairie sites 

characterized by a mix of native and 

non-native bunchgrasses (Jackson 1996, 

p. 39; Clark 2000, p. 3). Because the 

species occurs in both wet prairie and 

upland prairie habitat, conservation of 

representative populations in both of 

these habitat types is important to its 

conservation. As previously described, 

the long-term persistence of small 

populations will likely depend on 

augmentation with propagated 

individuals (Clark et al. 1995b, p. 23). 

Because there are very few surviving 

populations of E. decumbens var. 

decumbens, and they occur in both wet 

and upland prairie habitats, population 

augmentations must be sensitive to 

geographic variation within the species. 

Although it may be possible to 

reestablish functioning metapopulations 

across the range of the Fender’s Blue 

Butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens, it is highly unlikely that 

these metapopulations will ever be 

reconnected because of the distance 

between existing populations in an 

extremely fragmented landscape. Each 

metapopulation will therefore need to 

be independently viable, supporting 

multiple populations to reduce the risk 

of localized extinction. 

With so few remaining populations of 

each of these species, losing any one of 

the populations through a natural or 

human-caused event will measurably 

increase the likelihood of extinction for 

that species. For example, an accidental 

spraying of insecticide or herbicide on 

a Fender’s blue butterfly and Lupinus 

sulphureus ssp. kincaidii population 

could eliminate the entire population of 

one or both species. Hammond (2001, 

pp. 3, 4 and 2002, pp. 3, 4) documents 

a substantial Fender’s blue butterfly 

population decline in 1998 as the result 

of roadside herbicide spraying and 

bulldozer scraping throughout large 

portions of the habitat supporting a 

population in Yamhill County. 

Fortunately, this population is 

supported by three distinct lupine 


rwilkins on PROD1PC63 with RULES_2
63878 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

patches, and only two of the patches 

were impacted. The butterflies from the 

third patch were able to re-colonize the 

impacted areas, and the Fender’s blue 

butterfly population was able to recover 

by 2001 (Hammond 2002, pp. 3, 4). 

Although the likelihood of such an 

event is variable and difficult to predict, 

the extant small populations are at high 

risk of extirpation when they do occur. 

Primary Constituents Elements for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens 

Pursuant to our regulations, we are 

required to identify the known physical 

and biological features (primary 

constituent elements (PCEs)) essential to 

the conservation of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens. All areas designated as 

critical habitat for the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens are occupied, are within the 

species’ historic geographic range, and 

contain sufficient PCEs to support at 

least one life history function. 

Based on our current knowledge of 

the life history, biology, and ecology of 

the species and the requirements of the 

habitat to sustain the essential life 

history functions of the species, we have 

determined that the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens PCEs are as follows: 

The PCEs for Fender’s blue butterfly are: 

(1) Early seral upland prairie, wet 

prairie, or oak savanna habitat with a 

mosaic of low-growing grasses and 

forbs, an absence of dense canopy 

vegetation, and undisturbed subsoils. 

(2) Larval host plants Lupinus 

sulphureus ssp. kincaidii, L. arbustus, or 

L. albicaulis; 

(3) Adult nectar sources, such as: 

Allium acuminatum (tapertip onion), 

Allium amplectens (narrowleaf onion), 

Calochortus tolmiei (Tolmie’s mariposa 

lilly), Camassia quamash (small camas), 

Cryptantha intermedia (clearwater 

cryptantha), Eriophyllum lanatum 

(wooly sunflower), Geranium oreganum 

(Oregon geranium), Iris tenax (toughleaf 

iris), Linum angustifolium (pale flax), 

Linum perenne (blue flax), Sidalcea 

campestris (Meadow checkermallow), 

Sidalcea virgata (rose checker-mallow), 

Vicia cracca (bird vetch), V. sativa 

(common vetch), and V. hirsute (tiny 

vetch); 

(4) Stepping-stone habitat, consisting 

of undeveloped open areas with the 

physical characteristics appropriate for 

supporting the short-stature prairie oak 

savanna plant community (well drained 

soils), within 1.2 miles (∼2 km) of natal 

lupine patches. 

The PCEs for Lupinus sulphureus ssp. 

kincaidii are: 

(1) Early seral upland prairie, or oak 

savanna habitat with a mosaic of lowgrowing grasses and forbs, and spaces to 

establish seedlings or new vegetative 

growth; an absence of dense canopy 

vegetation; and undisturbed subsoils. 

(2) The presence of insect outcrossing 

pollinators, such as Bombus mixtus and 

B. californicus, with unrestricted 

movement between existing lupine 

patches. 

The PCE for Erigeron decumbens var. 

decumbens is: 

(1) Early seral upland prairie, wet 

prairie, or oak savanna habitat with a 

mosaic of low-growing grasses and 

forbs, and spaces to establish seedlings 

or new vegetative growth; an absence of 

dense canopy vegetation; and 

undisturbed subsoils. 

This designation is designed for the 

conservation of PCEs necessary to 

support the life history functions which 

were the basis for the proposal. Because 

not all life history functions require all 

the PCEs, not all critical habitat will 

contain all the PCEs. 

Units are designated based on 

sufficient PCEs being present to support 

one or more of the species’s life history 

functions. Some units contain all PCEs 

and support multiple life processes, 

while some units contain only a portion 

of the PCEs necessary to support the 

species’ particular use of that habitat. 

Where a subset of the PCEs is present at 

the time of designation, this rule 

protects those PCEs and thus the 

conservation function of the habitat. 

Methods 

As required by section 4(b)(1)(A) of 

the Act, we use the best scientific data 

available in determining areas that 

contain the features essential to the 

conservation of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

Kincaidii, and Erigeron decumbens var. 

decumbens. 

We reviewed available information 

that pertains to the habitat requirements 

of these species and evaluated all 

known species locations using data from 

the following sources—spatial data for 

known species locations from the 

Oregon Natural Heritage Information 

Center (ORNHIC 2004, entire data set), 

Washington Natural Heritage Program 

(WNHP 2005, entire data set), Corps 

(Corps 2004, entire data set), and Bureau 

of Land Management (BLM 2005, entire 

data set); United States Geological 

Survey (USGS 2000, data set for species 

range) 1:24,000 scale 3.75 digital 

orthophotographic quarter quadrangle 

images; recent biological surveys and 

reports; site-specific habitat evaluations 

(USFWS 2003a, pp. 1–34; USFWS 

2004a, pp. 1–576, 2004c, pp. 1–7); data 

in reports submitted during section 7 

consultations and by biologists holding 

section 10(a)(1)(A) recovery permits; 

research published in peer-reviewed 

articles and presented in academic 

theses or reports; and discussions with 

species experts. 

Criteria Used To Identify Critical 

Habitat 

We are designating critical habitat for 

specific areas that we have determined 

were occupied at the time of listing and 

that contain the primary constituent 

elements for Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens. 

Prior to the critical habitat proposal, 

Fender’s blue butterfly occupancy was 

recorded by simply reporting the 

location of occupied lupine patches 

(Schultz and Dlugosch 1999, pp. 231–

232). However, as previously described, 

adult butterflies utilize a variety of 

prairie species in addition to the lupine 

habitat. As a result, the final listing rule 

under-represented the known range of 

the Fender’s blue butterfly at the time of 

listing. Additionally, there are 

inconsistencies in the literature 

regarding how occupancy is 

documented. Often the occurrence data 

are presented by site; other times they 

are presented by population (Schultz et 

al. 2003, p. 62) or by documenting 

occupied prairie remnants (Schultz 

1998, p. 284; Schultz 2001, p. 1008), 

and at least one publication 

interchanges populations and sites 

(Wilson et al. 1997, p. 5). Furthermore, 

there is often an inconsistency in the 

number of populations that are reported 

since there is no defined convention for 

grouping sites into populations. For 

example, Severns (2003a, p. 222) 

documents 13 isolated populations 

based on Schultz’s (1998, p. 286) 

discussion of isolated prairie remnants, 

while other documents identify 16 

populations (Hammond 2004, p. 1; 

Schultz et al. 2003, p. 62). For this 

critical habitat designation, we have 

identified prairie habitat supporting 

Fender’s blue butterfly occurrences 

known at the time of listing, regardless 

of the presence or absence of lupine. In 

order to determine the extent of the area 

supporting these populations, we 

identified those areas within 1.2 miles 

(2 km) (Fender’s blue butterfly average 

dispersal distance) that contain the 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63879 

features essential to the conservation of 

this species. 

To identify areas of habitat containing 

the features essential for the 

conservation of all three species, we 

selected areas that represent the current 

distribution of each species, are of 

sufficient quality (including size) to 

contribute to functioning 

metapopulations (including areas 

necessary for connectivity between 

populations), or that represent unique 

ecological conditions. 

We selected occupied areas exhibiting 

the highest quality habitat by evaluating 

the following factors for each known 

occurrence—the presence of prairie 

indicator species, degree of habitat 

degradation (exotic species and 

succession to shrubs and trees), 

population size, and available 

surrounding prairie habitat to support 

population growth. Specifically, we 

selected occupied prairie habitat 

supporting a minimum of three prairie 

indicator species and providing 

adequate available habitat for 

population growth (surrounded by 

short-grass prairie habitat), and areas 

where habitat management activities 

would be effective at controlling threats 

(USFWS 2004a, entire data set; USFWS 

2005, pp. 1–19). 

We then selected areas that provide 

for population connectivity. As 

described in the Primary Constituent 

Elements section, connectivity is central 

to re-establishing functioning 

metapopulations for the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens and to ensure their longterm persistence. For the Fender’s blue 

butterfly, we evaluated areas providing 

the features essential to the conservation 

of the species within 1.2 miles (2 km) 

of the largest populations across the 

range of the species. For both L. 

sulphureus ssp. kincaidii and E. 

decumbens var. decumbens, we 

evaluated occupied areas within 5 miles 

(8 km) (estimated pollinating distance of 

the honeybee (Apis mellifera)) of the 

largest populations across the range of 

both species. 

All areas occupied at the time of 

listing that support the PCEs were 

screened using the criteria below, and 

the results were used to delineate the 

habitat containing the features essential 

to the conservation of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens: 

(1) We used our best professional 

judgment to select prairie remnants 

supporting core populations distributed 

across their respective ranges. Based on 

site-specific evaluations completed 

during field verification of occurrence 

data (USFWS 2003a, pp. 1–34, 2004a, 

entire data set), and various scientific 

reports (Severns 2004, pp. 1–12; 

Hammond 2004, pp. 1–35; Fitzpatrick 

2005, pp. 1–11; Kuykendall and Kaye 

1993a, pp. 1–41 + append., 1993b, pp. 

1–16 + append.; Clark et al. 1993, pp. 

1–55 + append.), core sites were 

identified as the largest, best-quality 

sites that significantly contribute to both 

local metapopulation function and 

rangewide distribution. 

From the areas selected according to 

the above principles, we eliminated 

some areas from further consideration if 

(1) the area was degraded and unlikely 

to be restorable; and (2) the area was 

small, highly fragmented, or severely 

isolated so that it would provide little 

or no long-term conservation value. 

These sites may prove to be important 

in the future if new species occurrences 

are identified in their vicinity. 

(2) In addition to habitat patches 

meeting criteria 1 above, we evaluated 

all prairie habitat in proximity to core 

populations. Specifically, these areas 

include habitat patches meeting the 

criteria below: 

(a) For the Fender’s blue butterfly, we 

selected areas providing the Primary 

Constituent Elements within 1.2 miles 

(2 km) of a core Fender’s blue butterfly 

population. These areas generally occur 

adjacent to or between core Fender’s 

blue butterfly populations. 

(b) For Lupinus sulphureus ssp. 

kincaidii, we selected areas located 

within 5 miles (8 km) of core 

populations supporting at least 0.25 ac 

(0.1 ha) of plant cover (Gisler et al., in 

litt., 2005, pp. 6, 7), and occupied areas 

with enough surrounding prairie habitat 

to support 0.25 ac (0.1 ha) of plant 

cover; 

(c) For Erigeron decumbens var. 

decumbens, we selected areas located 

within 5 miles (8 km) of core 

populations supporting a minimum of 

200 plants (Robinson et al., in litt., 2005, 

p. 4; Zwartjes, in litt., 2005, p. 2), and 

occupied areas with enough 

surrounding prairie habitat to support a 

minimum of 200 plants. Because we do 

not have plant counts for all 

populations, we used Erigeron 

decumbens var. decumbens average 

density information (Clark et al. 1993, p. 

23, 42 ) to estimate the area needed to 

support 200 plants, which equaled 0.6 

ac (0.24 ha). 

After screening prairie remnants using 

criteria 1 and 2 above, we completed a 

review of these areas to ensure 

populations occurring in atypical 

ecological settings were also included. 

Specifically, we determined that the 

selection criteria assured inclusion of 

Fender’s blue butterfly populations 

occurring on valley hillsides that may 

be climax grasslands, and of Erigeron 

decumbens var. decumbens populations 

occurring on both wet and upland 

prairie habitats. Because selection 

criteria number 1 identified core 

populations across the range of each 

species, it inherently included Lupinus 

sulphureus ssp. kincaidii populations in 

Douglas County, Oregon, where plants 

tend to be more shade tolerant. 

The PCEs were examined in 

combination with habitat maps, land 

use maps, aerial photographs, and 

occurrence data for populations meeting 

the above criteria, in order to identify 

the extent of prairie habitat supporting 

viable species occurrences. By working 

with local land managers and scientific 

experts familiar with the prairie habitat 

patches, we identified the prairie habitat 

boundaries for the occurrences meeting 

our criteria and digitized these prairie 

boundaries. We then asked the local 

land managers and scientific experts to 

review prairie boundary maps to ensure 

that only areas able to support the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens were 

included in our prairie boundaries. The 

proposed critical habitat units were 

delineated by overlaying extant species 

locations meeting criteria 1 and 2 above, 

and mapping prairie boundaries onto 

2000 USGS 1:24,000-scale 3.75 

orthophotographic quadrangle images. 

The mapped prairie boundaries formed 

the boundaries of critical habitat units. 

When determining final critical 

habitat map boundaries, we made every 

effort to avoid including developed 

areas such as buildings, paved areas, 

and other structures that lack any PCEs 

for the Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens. Any such 

structures and the land under them 

inadvertently left inside critical habitat 

boundaries of this final rule are 

excluded by text and are not designated 

as critical habitat. Therefore, Federal 

actions limited to these areas would not 

trigger section 7 consultation, unless 

they affect the species or primary 

constituent elements in adjacent critical 

habitat. 

We designated critical habitat in areas 

that we determined were occupied at 

the time of listing, and that contain 

sufficient primary constituent elements 

(PCEs) to support life history functions 

essential for the conservation of the 

species. All units were designated based 

on sufficient PCEs being present to 

support Fender’s blue butterflies, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens life 


rwilkins on PROD1PC63 with RULES_2

processes. Some units contained all 

PCEs and supported multiple life 

processes. Some segments contained 

only a single PCE necessary to support 

use of that habitat by Fender’s blue 

butterfly, L. sulphureus ssp. kincaidii, 

and E. decumbens var. decumbens. 

A discussion of each area designated 

as critical habitat is provided in the unit 

descriptions below. 

Special Management Considerations or 

Protections 

When designating critical habitat, we 

determine whether areas occupied at the 

time of listing and containing the 

primary constituent elements may 

require special management 

considerations or protections. 

Maintenance of open habitat conditions 

Since most prairie habitat within the 

range of these species is early-seral, 

active management is necessary for the 

conservation of all populations of 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens that occur 

in the proposed units described below. 

Without active management or natural 

disturbance, many populations may be 

lost to habitat succession (Wilson 1998a, 

p. 15, 1998b, p. 13; Wilson et al. 2003, 

p. 80) as trees and shrubs grow and 

outcompete early seral plants and shade 

or crowd out important early seral 

species such as L. sulphureus ssp. 

kincaidii, E. decumbens var. 

decumbens, and Fender’s blue butterfly 

nectar sources. Left unmanaged, entire 

lupine populations in these early seral 

habitats may disappear (Wilson et al. 

2003, pp. 79, 80). 

Fender’s blue butterfly and Lupinus 

sulphureus ssp. kincaidii 

Fender’s blue butterfly and Lupinus 

sulphureus ssp. kincaidii populations 

respond positively to habitat restoration. 

Mowing, burning, and mechanical 

removal of weeds, when done 

appropriately, have all been shown to 

benefit Fender’s blue populations. At 

sites managed by The Nature 

Conservancy (TNC), the Fender’s blue 

butterfly and L. sulphureus ssp. 

kincaidii populations increased 

following removal of noxious nonnative plants such as Rubus discolor 

(Himalayan blackberry) and Cytisus 

scoparius (Scotch broom) (Fitzpatrick 

2005, pp. 6, 7, 10, 11, 20). At Baskett 

Slough National Wildlife Refuge in 

western Oregon, Wilson and Clark 

(1997, p. 10, 11) studied the effects of 

controlled fire and mowing on the 

Fender’s blue butterfly and its native 

upland prairie. Although fire killed all 

larvae in treated patches, nearby 

unburned (untreated) patches provided 

a source of female Fender’s blue 

butterflies that were able to recolonize 

the entire burned (treated) area. Wilson 

and Clark (1997, pp. 10, 23) also found 

that in the year following mowing and 

burning treatments, Fender’s blue 

butterfly eggs were 10 to 14 times more 

abundant in treated plots than in 

undisturbed control plots. Woody plants 

were reduced by 45 percent with 

burning and by 66 percent with 

mowing. At the Corps’ Fern Ridge 

Reservoir, the Fender’s blue population 

has increased dramatically since fall 

mowing of L. sulphureus ssp. kincaidii 

patches has been implemented. The 

abundance of Fender’s blue butterfly 

eggs and L. sulphureus ssp. kincaidii 

has increased as blackberry bushes have 

been controlled in several test plots 

located on BLM lands in Eugene, 

Oregon (Kaye and Cramer 2003, p. 10). 

In general, Fender’s blue butterfly egg 

abundance increased substantially at 

sites treated to control non-native weeds 

(Schultz et al. 2003, p. 69). 

Erigeron decumbens var. decumbens 

Since periodic fire is believed to have 

historically maintained open prairie 

conditions, the use of prescribed 

burning as a maintenance tool has been 

investigated for restoring wet prairie 

habitats (Clark and Wilson 1998, p. 2). 

Studies investigating the effects of fire 

on Erigeron decumbens var. decumbens 

populations have been inconclusive as 

to whether fire promotes or inhibits 

populations (Wilson and Clark 1997, p. 

1). Additionally, research efforts 

investigating the control of woody 

vegetation in wet prairies demonstrated 

that none of the treatments (fire, 

mowing, and hand removal of woody 

vegetation) proved to be more effective 

than the others (Clark and Wilson 2000, 

p. 2). Mowing with the removal of cut 

material increased the presence of nonnative herbaceous species and should 

not be used as a management tool (Clark 

and Wilson 2000, p. 2). Because 

Erigeron decumbens var. decumbens 

does not tolerate the presence of woody 

vegetation, habitat management will be 

required for the long-term persistence of 

this species. Further investigation is 

needed to determine the most 

appropriate techniques for managing 

available habitat. Also, due to the low 

reproductive capability of the species, 

conservation of the E. decumbens var. 

decumbens will likely depend on 

artificially augmenting populations in 

areas where woody vegetation has been 

removed (Clark 2000, pp. 9–10). 

Reduce Habitat Fragmentation and 

Increase Population Size 

The Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens are at risk of 

inbreeding depression and site 

extirpation across their respective 

ranges because populations are small 

and isolated from one another (Jackson 

1996, p. 6; Schultz et al. 2003, p. 62, 

Severns 2003a, p. 222, 2003b, p. 334). 

All three species will benefit from 

reestablishing prairie plant patches in 

proximity to core populations. 

Efforts have been made to establish 

stepping stones of lupine habitat 

between core Fender’s blue butterfly 

populations occurring on BLM lands 

and Corps lands. A small patch of 

Lupinus sulphureus ssp. kincaidii 

planted in 2001, between two core 

Fender’s blue butterfly populations, 

became occupied by the species during 

the 2004 field season (Severns 2004, pp. 

7–8). While inconclusive, this 

observation provides evidence that 

Schultz’s (1998, p. 291) recommended 

stepping-stone reserve design may allow 

for successful dispersal between 

populations (Severns 2004, p. 12). 

Restoration of a metapopulation 

structure is considered necessary to 

restore viable populations (McIntire et 

al. in review, p. 1). 

McIntire et al. (in review, p. 1–47) 

completed a study to determine if 

fragmented prairie remnants near 

Eugene, Oregon, can be restored to a 

large functioning metapopulation that 

will persist over the long term. Several 

populations occur in this area but they 

are too far apart for the butterfly to 

disperse (greater than 1.2 miles (2 km)), 

and there are few intervening habitat 

patches. This study specifically looked 

at the conservation potential of 

restorable land located between the 

populations in a matrix of urban and 

agricultural land uses. Results of this 

study indicate that restoring existing 

prairie habitat to high quality may result 

in viable but unconnected populations 

unless habitat between populations is 

also reestablished. 

Expanding Erigeron decumbens var. 

decumbens populations will require 

more investigation into the roles of 

sexual and vegetative reproduction of 

this species. If sexual reproduction 

proves to be most important for 

population recruitment, mangers will 

need to focus on strategies that promote 

flowering, seed production, and 

seedling establishment (Clark 2000, p. 

9). However, if vegetative regeneration 

is predominant, managers will need to 

focus on activities that promote ramet 

(refers to individual plants in a clump, 


rwilkins on PROD1PC63 with RULES_2

each portion of which is identical with 

the original parent plant) production 

(Clark 2000, p. 9). Clark et al. (1995b, 

pp. 22–23) found that vegetative 

propagation is a viable technique for E. 

decumbens var. decumbens; 

populations may also be increased by 

sowing seeds under appropriate 

conditions, although this technique 

appeared to be less effective than 

vegetative propagation. 

Roadside, Power Right-of-Way, and 

Railroad Maintenance 

Many remaining populations of 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens populations 

occur in road rights of ways and are 

adversely affected by maintenance 

activities such as mowing or spraying of 

herbicides at the wrong time of year. A 

few L. sulphureus ssp. kincaidii 

populations along roads persist, likely 

because the routine maintenance 

provides open, full-sun conditions 

characteristic of L. sulphureus ssp. 

kincaidii habitat. 

Protection 

Several Lupinus sulphureus ssp. 

kincaidii and Erigeron decumbens var. 

decumbens populations occur on 

private lands and consequently remain 

unprotected by existing state or Federal 

statutes, which do not protect listed 

plants on private lands (Wilson et al. 

2003, p. 72). Limited conservation of 

plant populations may be provided 

under programs administered by the 

USDA Natural Resources Conservation 

Service, such as the Wetland Reserve 

Program. Current program rules 

prioritize disturbed agricultural lands 

over prairie remnant habitats; this limits 

the programs’ ability to protect existing 

plant populations that typically do not 

occur in disturbed agricultural lands. 

Wilson et al. (2003, p. 80) concluded 

that, lacking statutory protection, many 

of the plant populations occurring on 

private lands will likely be lost to 

development, agriculture, and invasion 

of weeds. 

The Fender’s blue butterfly depends 

primarily on Lupinus sulphureus ssp. 

kincaidii as a larval food source and for 

egg laying (ovipositioning). When 

populations of L. sulphureus ssp. 

kincaidii are destroyed, it also reduces 

the opportunity to expand existing 

Fender’s blue butterfly populations. 

Critical Habitat Designation 

We are designating 13 units as critical 

habitat for the Fender’s blue butterfly, 

13 units for Lupinus sulphureus ssp. 

kincaidii, and 9 units for Erigeron 

decumbens var. decumbens (see Figure 

1). The critical habitat areas described 

below represent our best assessment at 

this time of areas determined to be 

occupied at the time of listing, 

containing the primary constituent 

elements essential for the conservation 

of the species, and that may require 

special management.

We present brief descriptions of all 

units, and reasons why they meet the 

definition of critical habitat for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens, below. 

Fender’s blue butterfly 

In total, we are designating 13 critical 

habitat units, each of which represents 

areas of habitat containing the features 

essential to the conservation of existing 

core populations of Fender’s blue 

butterfly throughout its range. Each unit 

was occupied at the time of listing, and 

each unit represents a population that is 

currently isolated from other 

populations. To simplify unit 

descriptions, we have grouped units 

that with proper management and 

restoration, and may function as larger 

connected metapopulations.

63884 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

Unit 1 for Fender’s blue butterfly (Units 

FBB–1A and 1B) 

Units FBB–1A and 1B encompass 

approximately 6.2 ac (2.5 ha) and 14.1 

ac (5.7 ha), respectively, of private land 

occurring within northern Yamhill 

County and within the Oak Ridge 

habitat network. The Oak Ridge 

butterfly population is supported by 

three separate habitat patches, and the 

population has been monitored 

annually since 1993 (Hammond 2004, 

pp. 1, 3). The population has become 

much larger over the last 3 years, with 

an estimated 259 butterflies in 2004 

(Hammond 2004, pp. 3, 34). FBB–1A 

represents the northernmost known 

occupied habitat patch in the current 

range of Fender’s blue butterfly, and 

occurs along both the east and west 

sides of Oak Creek Road. FBB–1B is 

located approximately 0.7 miles (1.1 

km) south of FBB–1A along both the 

east and west sides of Oak Creek Road, 

near the junction with Fairdale Road. 

The prairie habitat within FBB–1A and 

FBB–1B contains the PCEs essential to 

the conservation of this core population. 

In recent years the Oak Ridge butterfly 

metapopulation has been evenly 

distributed among the three lupine 

patches. However, 10 years of 

monitoring reports for this population 

indicate that the number of individuals 

supported by each habitat patch has 

increased and decreased annually, with 

one habitat patch disproportionately 

supporting the population each year. 

The population fluctuations 

documented at these sites are attributed 

to roadside maintenance and presence 

of invasive species (Hammond 2002, pp. 

3, 4; Hammond 2004, pp. 5, 33). The 

overall population has remained 

relatively stable, likely because its 

distribution among the three habitat 

patches provides opportunity for 

recolonization of impacted habitat 

patches (Hammond 2004, pp. 4–5). The 

prairie habitat within and between 

FBB–1A and 1B should be managed to 

allow for growth and expansion of this 

relatively small population in order to 

achieve and maintain the population. 

Unit 1 for Fender’s blue butterfly 

contains habitat features that are 

essential to the continued persistence of 

the species’ core population throughout 

its range. Establishing stepping-stone 

habitat between FBB–1A and 1B will 

contribute to a more connected 

functioning metapopulation. However, 

at this time we do not have enough 

information to identify additional 

potential habitat for population 

expansion that may be necessary to 

meet delisting criteria. The habitat 

identified in FBB–1A and 1B has the 

features essential to the conservation of 

Fender’s blue butterfly; has one of the 

largest remaining Fender’s blue butterfly 

metapopulations; supports the 

butterfly’s primary host plant, Lupinus 

sulphureus ssp. kincaidii; occurs at the 

northernmost extent of the species’

range (Hammond 2004, p. 5); and is 

surrounded by prairie habitat available 

for population expansion. 

Unit 2 for Fender’s blue butterfly (Unit 

FBB–2) 

Unit FBB–2 consists of approximately 

51 ac (20.6 ha) of private lands within 

southern Yamhill County. The Gopher 

Valley butterfly population has been 

monitored annually since 1995 

(Hammond 2004, p. 7), and has 

remained stable with a relatively low 

number of individuals consistently 

being reported (compared to other stable 

populations) (Hammond 2004, p. 35). 

The Lupinus sulphureus ssp. kincaidii 

habitat supporting this population 

occurs in two habitat patches scattered 

along the east and west sides of Gopher 

Valley Road. The largest distance 

separating lupine patches is 

approximately 0.12 miles (0.2 km). This 

population is threatened by the limited 

availability of nectar sources, presence 

of invasive species, and roadside 

maintenance activities. 

With proper management of the 

prairie habitat surrounding the 

population located within the FBB–2 

unit boundary, the habitat provides 

opportunities for population growth and 

expansion of both Fender’s blue 

butterfly and Lupinus sulphureus ssp. 

kincaidii. Unit FBB–2 provides ease of 

Fender’s blue butterfly movement 

between lupine habitat patches, and to 

all the features essential to the 

conservation of the species. Given the 

increased size of the lupine patch at the 

Deer Creek Park site (Hammond 2005, p. 

8), this area will substantially contribute 

to the conservation of the Fender’s blue 

butterfly. The habitat in FBB–2 has the 

features essential to the conservation of 

Fender’s blue butterfly; one of the 

largest remaining Fender’s blue butterfly 

populations in this portion of the 

butterfly’s range; supports one of 

Fender’s blue butterfly’s primary host 

plants; provides the foundation for the 

existence of the species in this portion 

of its range; and has surrounding prairie 

habitat available for population 

expansion. In addition, Hammond 

(2005, pp. 8, 9) identified an expanding 

L. sulphureus ssp. kincaidii population 

at Deer Creek Park that now supports 

Fender’s blue butterfly, increasing the 

size and long-term viability of this 

metapopulation. 

Unit 3 for Fender’s blue butterfly (Unit 

FBB–3) 

Unit FBB–3 encompasses 

approximately 3.6 ac (1.5 ha) of 

primarily State-owned lands within 

northern Polk County. The Mill Creek 

butterfly population has been monitored 

annually since 1993 (Hammond 1993, 

pp. 18, 24; Hammond 2004, pp. 9, 10) 

and the overall number of individuals 

has increased over the past 3 years 

(Hammond 2004, p. 10). The lupine 

habitat supporting this population 

occurs in two patches scattered along 

the northeast and southwest sides of 

Highway 22, near the intersection with 

Mill Creek Road. The Oregon 

Department of Transportation (ODOT) 

owns most of the habitat supporting this 

population. Hammond (2004, p. 10) 

documented the threats to this unit as 

largely the presence of invasive grasses 

and shrubs that have overgrown the 

habitat, suppressing the lupine and 

Erigeron decumbens var. decumbens 

populations occupying this prairie 

remnant. 

Habitat management activities 

implemented by ODOT in 2000 resulted 

in a large growth flush of Lupinus 

sulphureus ssp. kincaidii and an 

increased number of Fender’s blue 

butterflies. This demonstrates that 

appropriate management of this site can 

provide for population growth and 

expansion. The habitat in unit FBB–3 

supports the butterfly’s primary host 

plant; the Fender’s blue butterfly 

population size has been increasing over 

the last few years. 

Unit 4 for Fender’s blue butterfly (Units 

FBB–4A and 4B) 

Units FBB–4A and 4B encompass 

approximately 748.4 ac (302.9 ha) and 

416.1 ac (168.4 ha), respectively, of 

private and Federal land occurring 

within northern Polk County. Units 

FBB–4A and 4B are located adjacent to 

Highway 22 approximately 5.5 miles 

(8.8 km) northeast of the City of Dallas. 

An estimated 64 percent of the habitat 

encompassed within Unit FBB–4 occurs 

within the boundaries of the Service’s 

Baskett Slough National Wildlife Refuge 

(Refuge) and approximately 36 percent 

of the prairie habitat occurs on adjacent 

private lands. Refuge biologists have 

documented the occurrence of the PCEs 

throughout the habitat within FBB–4A 

and 4B and also the Fender’s blue 

butterfly’s utilization of these areas 

(USFWS 2005, Smith, in litt.a, pp. 2, 3). 

Many of the populations occurring in 

FBB–4A have been monitored annually 

since 1993 (Hammond 2004, p. 17), and 

the populations occupy ten separate 

patches of Lupinus arbustus which are 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63885 

scattered across the unit. Between 1993 

and 2001, habitat conditions steadily 

declined in many areas due to 

encroachment of grasses and brush in 

the upland prairie habitat (Hammond 

2004, p. 18). Such habitat conditions 

adversely impacted not only the 

Fender’s blue butterfly but also the 

population of Erigeron decumbens var. 

decumbens supported within FBB–4A. 

Recent survey results indicate that this 

metapopulation increased dramatically 

in size during 2003–2004 (Hammond 

2004, p. 18). The total population size 

was estimated at 223 individuals in 

2001 and approximately 1,368 

individuals in 2004. 

Unit FBB–4B is located approximately 

0.12 miles (0.2 km) from FBB–4A with 

predominately agricultural lands 

occurring between the areas supporting 

this metapopulation. Unit FBB–4 (FBB–

4A and 4B) supports the largest known 

Fender’s blue butterfly metapopulation 

and the largest contiguous occupied 

prairie patch in the range of the species. 

This relatively large, contiguous prairie 

habitat is one of a few occupied 

remnants occurring on valley hillsides; 

most remaining populations occur on 

the valley floor. The open nature of the 

lands occurring between FBB–4A and 

4B increases the potential for 

individuals to successfully disperse 

among habitat patches. The habitat in 

this unit has the features essential to the 

conservation of the species; it supports 

the largest known metapopulation, 

consists of several connected 

populations and provides an abundance 

of nectaring and dispersal habitat that 

allows for population growth and 

expansion. 

Unit 5 for Fender’s blue butterfly (Unit 

FBB–5) 

Unit FBB–5 consists of approximately 

12.3 ac (5 ha) of private lands within the 

central portion of Polk County. Unit 

FBB–5 is located near the junction of 

Highway 223 and Oakdale Avenue and 

largely falls within the City of Dallas’

urban-growth boundary. Although 

Hammond (Hammond and Wilson 1993, 

pp. 10, 15; 2004, pp. 10, 12) has 

estimated the size of the Dallas 

population since 1991 (Hammond 1996, 

p. 13), he documents that he has been 

unable to access the site for over seven 

years and has been limited to visuallyobstructed roadside observations. The 

Fender’s blue butterfly needs special 

management in this unit because the 

population is threatened by the limited 

availability of food plants, presence of 

invasive species, and the impacts 

associated with the encroachment of 

urban development. Hammond (2004, p. 

12) has documented the removal of 

several acres of Fender’s blue butterfly 

habitat adjacent to this unit over the last 

ten years for residential development. 

Appropriate management of the 

prairie habitat within FBB–5 should 

provide opportunity for population 

growth and expansion population. Unit 

FBB–5 provides the habitat containing 

the features essential for the continued 

persistence of this core population. 

Unit 6 for Fender’s blue butterfly (Units 

FBB–6A and 6B) 

Units FBB–6A and 6B encompass 

approximately 2.4 ac (1 ha) and 15.9 ac 

(6.4 ha), respectively, of private lands 

occurring within southern Polk County. 

Unit FBB–6A is located along McCaleb 

Road near Cooper Creek and Unit FBB–

6B is approximately 0.8 mile (1.4 km) 

south of FBB–6A along Monmouth 

Highway. Several Fender’s blue 

butterfly populations historically 

occurring south of Dallas, Oregon, have 

been extirpated over the last decade 

(Hammond 2004, p. 12, 13). The habitat 

encompassed within FBB–6 (FBB–6A 

and 6B) supports the core butterfly 

population occurring at the southern 

end of the Dallas/Polk County 

functioning network and has been 

monitored annually since 1994 

(Hammond 2005, p. 16). 

Reintroductions of Lupinus 

sulphureus ssp. kincaidii or 

augmentations may be necessary at 

extirpated sites to provide steppingstone habitat between FBB–5 and FBB–

6. Unit FBB–6 provides the habitat 

containing the features essential to the 

persistence of this core population, as 

evidenced by an increasing butterfly 

population size over the last few years; 

it is one of the largest remaining 

Fender’s blue butterfly populations in 

this portion of its range and it is one of 

two core, isolated populations providing 

the ‘‘backbone’’ of the Dallas/Polk 

County functioning network. 

The larval host plant found in FBB–

6B is Lupinus albicaulis, and based on 

roadside observations, Hammond (2004, 

p. 12) estimates several hundred 

butterflies occupy this habitat. Since L. 

albicaulis is a short-lived perennial, 

Hammond (2004, p. 12) documents that 

without periodic disturbance this 

butterfly population may disappear 

more quickly than populations using L. 

sulphureus ssp. kincaidii and L. 

arbustus as a host plant. However, L. 

albicaulis is the primary host plant for 

Puget blue butterfly (Icaricia icarioides 

blackmorei) and appears to serve the 

Puget blue quite well (Schultz, in litt.b, 

2005). Additionally, another roadside 

population (McTimmonds Valley) of 

Polk County Fender’s blue butterfly 

supported by L. albicaulis (Hammond 

2002, p. 15) has remained stable for over 

a decade (Hammond 2004, pp. 13, 14). 

FBB–6A supports a roadside 

population of Lupinus sulphureus ssp. 

kincaidii and is located between FBB–

6B and a Fender’s blue butterfly site 

where, in spite of surveys, individuals 

have not been seen for 2 years. FBB–6A 

provides stepping-stone habitat for 

Fender’s blue butterfly.. 

Units 7, 8, and 9 for Fender’s blue 

butterfly (Units FBB–7, FBB–8, and 

FBB–9) 

Units FBB–7, FBB–8, and FBB–9 

collectively represent the areas of 

habitat containing the features essential 

to the conservation of the Fender’s blue 

butterfly populations in northern 

Benton County. This area is located in 

the central region of the species’ range 

and consists of two large and one 

medium-sized populations that are 

isolated from one another. The 

availability of habitat in each of these 

units provides opportunity for 

population growth and expansion, with 

appropriate stepping-stone habitat 

conditions available for facilitating 

movement within units. 

Each of these units has features that 

are essential to the conservation of the 

species because there is surrounding 

prairie habitat available for 

metapopulation expansion, and the 

units collectively support three of the 

largest remaining Fender’s blue butterfly 

populations in this portion of the 

species’ range. Additionally, these 

populations are located in relatively 

close proximity to one another, thus 

increasing the potential for interaction 

between populations. Stepping-stone 

habitat between FBB–7, FBB–8, and 

FBB–9 will likely be necessary for these 

currently isolated populations to 

function as a larger metapopulation. The 

habitat included within each of these 

units provides the foundation for longterm persistence of each respective 

isolated population. 

Unit 7 for Fender’s blue butterfly (Unit 

FBB–7) 

Unit FBB–7 consists of approximately 

11.5 ac (4.6 ha) of private and State 

lands within Benton County. The 

habitat in this unit, uniquely located in 

a meadow surrounded by forested land, 

supports the second largest known 

Fender’s blue butterfly population and 

occurs in McDonald Forest located off 

Oak Creek Road. Approximately 15 

percent of the habitat supporting the 

PCEs within FBB–7 occurs on Oregon 

State University lands and the 

remaining 85 percent occurs on private 

lands. This Fender’s blue butterfly 

population has been monitored 


rwilkins on PROD1PC63 with RULES_2
63886 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

annually since 1993 (Hammond 2004, 

pp. 26–27) and recent studies indicate 

that this population has the highest 

chance of long-term persistence based 

on population trend data (Schultz et al. 

2003, pp. 67–68). 

This population of Fender’s blue 

butterfly is threatened by the 

encroachment of invasive grasses and 

succession to forest, especially in 

narrow areas of the meadow where tree 

encroachment could block-off portions 

of the habitat and isolate portions of the 

populations (Hammond 2004, p. 27). 

Although a management plan has not 

been completed for this unit, the 

landowner is interested in maintaining 

the prairie habitat for the butterfly. In 

cooperation with Oregon State 

University scientists, the landowner is 

studying appropriate management 

techniques for controlling invasive 

Brachypodium sylvaticum (false brome). 

Unit FBB–7 provides a diverse 

composition of high quality habitat 

utilized by all life stages of the Fender’s 

blue butterfly. 

Unit 8 for Fender’s blue butterfly (Unit 

FBB–8) 

Unit FBB–8 encompasses 

approximately 716.7 ac (290 ha) of 

private lands within Benton County. 

This unit is located in Wren, Oregon, 

between Kings Valley Highway, 

Cardwell Hill Road and Blakesly Creek 

Road, approximately 2 miles (3.2 km) 

southwest of Unit FBB–7. Several of the 

Fender’s blue butterfly populations 

occupying this unit have been surveyed 

regularly since 1991 (Hammond and 

Wilson 1993, p 10, 22; Hammond 1997, 

p. 6; Hammond 1999, p. 20; Hammond 

2001, p. 22; Hammond 2003, pp. 22, 23; 

Hammond 2004, pp. 23–25; Hammond 

2005, p. 26). 

A new Fender’s blue butterfly 

population has been documented using 

a large population of Lupinus 

sulphureus ssp. kincaidii located 

between two of the regularly monitored 

populations of Fender’s blue butterfly 

(Hammond 2004, p. 23). The powerline 

right-of-way that runs across Unit FBB–

8 appears to play a significant role in 

Fender’s blue butterfly dispersal 

between the L. sulphureus ssp. kincaidii 

populations scattered across this large 

contiguous high quality prairie (USFWS 

2004a, 2004c). The relatively ‘‘pristine’’

(Hammond 2004, p. 23), large prairie 

habitat included within Unit FBB–8 

contains the features essential for all life 

stages of this Fender’s blue butterfly 

metapopulation. 

Unit 9 for Fender’s blue butterfly (Unit 

FBB–9) 

Unit FBB–9 consists of approximately 

48.5 ac (19.6 ha) of private lands located 

north of Philomath. The habitat occurs 

primarily to the south of West Hills 

Road and to the west of 19th Street. The 

Greenbelt Land Trust recently obtained 

a conservation easement for 51 percent 

of the prairie habitat supporting this 

population. Adult Fender’s blue 

butterfly individuals have been 

observed using the nectaring habitat in 

this remnant prairie and many of the 

Lupinus sulphureus ssp. kincaidii 

populations scattered throughout the 

unit. The Fender’s blue butterfly 

population utilizing the eastern portion 

of this site has been monitored annually 

since 1999 (Hammond 2005, p. 34), with 

the first observation of individuals 

occurring in 1992 (Hammond and 

Wilson 1993, pp. 10, 21). Threats to this 

site include encroachment of invasive 

species, trees and shrubs, and a small 

portion of the Unit FBB–9 is located 

along West Hills Road and impacted by 

roadside maintenance activities. Unit 

FBB–9 provides the habitat features 

essential for all life stages of this 

butterfly population, and is one of the 

core populations.. 

Units 10, 11, and 12 for Fender’s blue 

butterfly (Unit FBB–10, FBB–11, and 

FBB–12) 

Units FBB–10, FBB–11, and FBB–12 

support the core populations of the 

species in the southern portion of their 

range. Collectively, these units provide 

the foundation for the West Eugene 

habitat network. 

This area supports three core 

populations that are mostly isolated 

from one another (greater than 0.93 

miles (1.5 km) from the nearest 

occupied lupine patch) with steppingstone populations located between core 

populations. The availability of habitat 

within each of these units provides 

opportunity for population growth and 

expansion, as well as areas appropriate 

for stepping-stone habitat that will 

facilitate ease of movement within 

units. Each of these units provide 

habitat with features essential to the 

conservation of the species; they 

collectively support two of the largest 

remaining Fender’s blue butterfly 

metapopulations (FBB–10 and FBB–12); 

the two metapopulations are located in 

relatively close proximity to one another 

providing a unique opportunity to 

reestablish a larger connected set of 

populations that functions as a viable 

metapopulation; the butterfly 

populations are all supported by 

Lupinus sulphureus ssp. kincaidii; and 

there is surrounding prairie habitat 

available for population expansion. 

Stepping-stone habitat in FBB–11 is 

necessary to provide connectivity 

among core butterfly populations to 

ensure the long-term persistence of this 

metapopulation. 

Unit 10 for Fender’s blue butterfly 

(Units FBB–10A, 10B, 10C, 10D, and 

10E) 

Unit FBB–10A–E encompass 

approximately 487.4 ac (197.2 ha) of 

prairie habitat in Lane County, Oregon. 

The prairie habitat included within 

FBB–10A–E occurs on BLM and Corps 

land (63 percent), private lands (33 

percent), and County lands (4 percent). 

Unit FBB–10A, 10B, and 10C 

collectively support two core 

metapopulations of Fender’s blue 

butterfly and Lupinus sulphureus ssp. 

kincaidii that have been surveyed 

annually since 1993 (Severns 2004, p. 2; 

Fitzpatrick 2005, p. 2). Within FBB–

10A, 84 percent of the area occurs on 

Corps property located near Shore Lane, 

NE Fern Ridge Reservoir. 

The populations occupying FBB–10A 

require tall-oat grass (Arrhenatherum 

elatius) management because this 

invasive grass now covers 100 percent 

of the habitat supporting all six 

populations (Severns 2004, p. 1). 

Nevertheless, the 2004 population 

surveys reported the largest number of 

butterflies ever observed at the site; the 

population size more than doubled 

between 2003 and 2004. The Army Corp 

of Engineers has reestablished 

populations of Lupinus sulphureus ssp. 

kincaidii between Fender’s blue 

butterfly populations located within this 

unit to provide butterfly stepping-stone 

habitat and increase connectivity. In 

2001, a small patch of L. sulphureus ssp. 

kincaidii was planted on the side of a 

spoil mound, on the south side of the 

Amazon Canal. The Fender’s blue 

butterfly was documented using this 

lupine patch during the 2004 field 

season. This demonstrates that the 

recommended stepping-stone reserve 

design (Schultz 1998, p. 291) will allow 

for successful dispersal between core 

populations occurring on Corps lands in 

FBB–10A and on BLM lands in FBB–

10C (Severns 2004, p. 1). The steppingstone habitat is important to 

establishing a viable, connected 

Fender’s blue butterfly metapopulation 

(McIntire et al. in review, pp. 1–47; 

Severns 2004, p. 1). 

Portions of the habitat occurring on 

BLM land within FBB–10C are severely 

threatened by the closed canopy cover 

of Rubus armeniacus that has overtaken 

large areas of the site (Kaye 2004). 

Fender’s blue butterfly populations

Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63887 

supported by the habitat within FBB–

10B would benefit from adult nectar 

source augmentations (Severns 2004, p. 

1). Habitat management will be 

necessary to increase the size and 

connectivity of butterfly populations by 

restoring additional stepping-stone 

habitat patches that enhance the 

connection between the core 

populations occupying FBB–10A and 

FBB–10C (McIntire et al. in review, pp. 

1–47). Units FBB–10D and 10E provide 

essential features for the conservation of 

the species and stepping-stone habitat to 

populations occurring in Units FBB–11 

and FBB–12 (McIntire et al. in review, 

pp. 1–47). Unit FBB–10A–E provides 

the habitat containing the features 

essential for two butterfly populations. 

This unit includes one of the most 

extensive contiguous prairie remnants, 

which increases the potential for 

connectivity between these two core 

populations. This prairie remnant 

provides the foundation for 

reestablishing a large functioning 

metapopulation within the West Eugene 

Habitat Network. 

Unit 11 for Fender’s blue butterfly 

(Units FBB–11A, 11B, 11C, 11D, 11E, 

11F, 11G, 11H, and 11I) 

Unit FBB–11A consists of 15.5 ac (6.3 

ha) of privately owned land. FBB–11B 

includes approximately 14 ac (5.7 ha) of 

primarily BLM land (94 percent) with 6 

percent occurring on private lands. 

FBB–11C encompasses approximately 

22 ac (9 ha) with 94 percent occurring 

on BLM land and 6 percent on private 

lands. FBB–11D encompasses 

approximately 29.3 ac (11.9 ha) with 68 

percent on federally owned lands and 

32 percent on private lands. FBB–11E 

consists of approximately 4.4 ac (1.8 ha) 

of land entirely owned by Lane County. 

FBB–11F encompasses approximately 

28.8 ac (11.6 ha) with 80 percent on 

federally owned lands, 9 percent on 

state owned lands and 11 percent on 

private lands. FBB–11G encompasses 

approximately 4.6 ac (1.9 ha) with 67 

percent on Federal lands and 33 percent 

on private lands. FBB–11H consists of 

approximately 58.6 ac (23.7 ha) with 97 

percent on Federal lands, less than 2 

percent on private lands, and less than 

1 percent on county lands. FBB–11I 

encompasses approximately 51.5 ac 

(20.8 ha) with 75 percent occurring on 

Federal lands and 25 percent on private 

lands. Most of the lupine populations 

scattered across the prairie habitat 

within this unit are relatively small, but 

the habitat supporting them is important 

to the long-term viability of a larger 

functioning Fender’s blue butterfly 

metapopulation in this southern portion 

of the species range (McIntire et al. in 

review, pp. 1–47). 

The area included within this unit 

provides needed stepping-stone habitat 

between the BLM/Army Corp of 

Engineers metapopulation to the 

northwest and The Nature Conservancy 

(TNC) metapopulations to the southeast 

(McIntire et al. in review, pp. 1–47). 

Local land managers recently surveyed 

this area to identify habitat patches 

suitable for reestablishing Lupinus 

sulphureus ssp. kincaidii populations as 

stepping-stones for the Fender’s blue 

butterfly (McIntire et al. in review, pp. 

1–47). The areas identified occur within 

this unit boundary will need to be 

enhanced to increase the size and 

connectivity of butterfly populations by 

restoring patches between core 

metapopulations within FBB–10 and 

FBB–12 (McIntire et al. in review, pp. 

1–47). Unit FBB–11 (FBB–11A, 11B, 

11C, 11D, 11E, 11F, 11G, 11H, and 11I) 

provides the features essential for all life 

stages of this butterfly population 

because it includes habitat to reestablish 

connectivity between two of the largest 

remaining metapopulations, and it 

increases viability of all populations in 

this portion of the species’ range. The 

habitat included within FBB–11 is 

important for reestablishing 

connectivity between existing 

metapopulations and providing for a 

large functioning metapopulation 

(McIntire et al. in review, pp. 1–47). 

Unit 12 for Fender’s blue butterfly 

(Units FBB–12A and 12B) 

Units FBB–12A and 12B encompasses 

approximately 114.4 ac (46.3 ha) near 

the intersection of Bailey Hill Road and 

Bertelson Road, with the majority of this 

land occurring on TNC property. The 

Lupinus sulphureus ssp. kincaidii and 

Fender’s blue butterfly populations are 

scattered across the 508 ac (206 ha) of 

remnant prairie known as the Willow 

Creek Natural Area (Fitzpatrick 2005, 

pp. 2, 27). FBB–12A and 12B function 

as a metapopulation and collectively 

represent the third largest Fender’s blue 

butterfly metapopulation across the 

range of the species. The populations 

occurring within this unit have been 

monitored annually since 1993 

(Fitzpatrick 2005, p. 2). 

The habitat within FBB–12A and 12B 

is threatened by exotic vegetation and 

succession to woody vegetation. To 

ensure a viable, connected 

metapopulation in west Eugene, the area 

within this unit should be enhanced to 

provide opportunity for population 

growth and expansion (McIntire et al. in 

review, pp. 1–47). Unit FBB–12 (FBB–

12A and 12B) provides habitat features 

essential to the conservation of the 

species; it includes some of the highest 

quality remaining upland prairie, and 

supports the largest core 

metapopulation in this portion of the 

species range. 

Unit 13 for Fender’s blue butterfly (Unit 

FBB–13): 

Unit FBB–13 encompasses 

approximately 132.5 ac (53.6 ha) of 

private land that supports several 

patches of primarily Lupinus arbustus 

scattered across the remnant prairie. 

The Fender’s blue butterfly population 

occupying this unit has been monitored 

since 1993 (Fitzpatrick 2005, p. 7). This 

habitat supports one of the largest 

remaining butterfly populations and the 

highest diversity of native plants 

documented for Fender’s blue butterfly 

habitat (Hammond 1994, p. 45). This 

butterfly population occurs on a valley 

hillside and is supported by habitat that 

appears to be stable climax grassland 

which is very different than the 

populations growing on the valley floor 

(Hammond and Wilson 1993, p. 45; 

Hammond 1994, p. 45). Hammond and 

Wilson (1993, p. 45) indicate this 

population should be regarded as a 

distinct ecological segregate that should 

be preserved as a unique population. 

The size, quality and its unique 

ecological conditions make this unit 

important to the conservation of the 

species. 

Lupinus sulphureus ssp. kincaidii 

In total, we are designating 13 critical 

habitat units, each of which represents 

areas of habitat containing the features 

essential to the conservation of core 

populations of Lupinus sulphureus ssp. 

kincaidii throughout its range. To 

simplify unit descriptions, we have 

grouped units that are within pollinator 

distance of one another, and that may 

function as larger, connected 

metapopulations with proper 

management and restoration. 

Unit 1 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–1) 

Unit KL–1 consists of approximately 

4 ac (1.6 ha) of private land in Lewis 

County, Washington. There are only a 

few small populations of Lupinus 

sulphureus ssp. kincaidii remaining in 

Washington. These populations are 

highly disjunct from the Willamette 

Valley populations with an estimated 81 

miles (131 km) separation. Unit KL–1 

includes the highest quality prairie 

habitat supporting L. sulphureus ssp. 

kincaidii in this northernmost extent of 

its range. This lupine patch is located 

approximately 0.8 km from lands 

supporting three lupine patches that are 

being managed to promote the 


rwilkins on PROD1PC63 with RULES_2
63888 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

conservation of the species. The prairie 

habitat found in Lewis County, 

Washington, will likely need to be 

actively managed to expand the current 

L. sulphureus ssp. kincaidii populations 

and re-establish lupine patches in 

relative close proximity (3–5 miles (5–

8 km)) to one another. At this time, we 

do not have enough information to 

identify additional potential habitat for 

population expansion, which will likely 

be necessary for these populations to 

function as a viable metapopulation. 

The habitat in this unit has the features 

essential to the conservation of L. 

sulphureus ssp. kincaidii; it supports 

one of the remaining L. sulphureus ssp. 

kincaidii populations in the northernmost extent of the species’ range; is 

close enough to other lupine patches to 

function as a larger metapopulation; and 

there is surrounding prairie habitat 

available for population expansion. 

Unit 2 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–2 A and 2B) 

Unit KL–2A and 2B encompass 

approximately 6.25 ac (2.5 ha) and 14.1 

ac (5.7 ha) respectively, of private land 

in northern Yamhill County. KL–2A 

supports Lupinus sulphureus ssp. 

kincaidii patches along both the east 

and west sides of Oak Creek Road. KL–

2B is located approximately 0.68 miles 

(1.1 km) south of KL–2A along both the 

east and west sides of Oak Creek Road, 

near the junction with Fairdale Road. 

Yamhill County is responsible for 

roadside maintenance activities along 

Oak Creek Road that may adversely 

impact these plant populations. The 

prairie habitat within KL–2 (KL–2A and 

2B) includes the PCEs essential to the 

conservation of this core population. 

Habitat management will be necessary 

to maintain the short-grass stature of the 

native prairie and provide the habitat 

conditions essential to the conservation 

of L. sulphureus ssp. kincaidii. The 

Fender’s blue butterfly uses L. 

sulphureus ssp. kincaidii at this site as 

a primary host plant and 100 percent of 

Unit KL–1 is included within Unit FBB–

1. 

Threats to Unit KL–2 include impacts 

from the timing and extent of road 

maintenance activities, domestic 

livestock management that reduces 

Lupinus sulphureus ssp. Kincaidii 

viability and distribution, and the 

presence of invasive species (Hammond 

2004, p. 5, 33). The distribution of 

habitat patches in relatively close 

proximity to each other has likely 

contributed to the persistence of this 

population. Impacts to this population 

over the years have typically affected 

only one habitat patch at any given time 

since they are scattered across the 

prairie habitat. Severns (2003a, p. 227) 

indicates that the stepping-stone reserve 

design recommended for the 

conservation of Fender’s blue butterfly 

will also benefit L. sulphureus ssp. 

kincaidii populations. Increasing the 

number of lupine patches in close 

proximity to one another will likely 

increase the chances for outcrossing 

pollination. 

In order for the species to persist over 

the long term, this population will 

likely need to function with other 

populations to form a more viable 

metapopulation. At this time we do not 

have enough information to identify 

additional potential habitat for 

population expansion that will be 

necessary for this metapopulation to 

meet delisting criteria. Although there 

are other reported occurrences in the 

general vicinity those sites do not meet 

the minimum patch size, are highly 

degraded, or are restricted by roads 

without potential for population 

expansion, and thus are not considered 

to have the features essential to the 

conservation of this population. Unit 

KL–2 provides the habitat features 

essential for the continued persistence 

of a core population in this portion of 

the species range. Even with a relatively 

small population size, habitat within 

Unit KL–2 supports one of the largest 

remaining Lupinus sulphureus ssp. 

kincaidii populations that represents the 

northernmost Willamette Valley 

population, and provides surrounding 

prairie habitat for population expansion. 

Units 3 and 4 of Lupinus sulphureus 

ssp. kincaidii (Unit KL–3 and KL–4) 

Units KL–3 and KL–4 each support a 

Lupinus sulphureus ssp. kincaidii 

population that collectively, may 

function as a larger metapopulation. 

These units are located approximately 

2.3 miles (3.7 km) apart and likely have 

rare cross-pollination events. Active 

management may be necessary to both 

enhance these populations and identify 

opportunities to increase pollinator 

connectivity among units. At this time 

we do not have enough information to 

identify additional potential habitat for 

population expansion, which will likely 

be necessary for these populations to 

function as a larger metapopulation. 

Although there are other small, mostly 

roadside populations recorded within 

the estimated 5 miles (8 km) pollinator 

distance, most are highly degraded, 

presumed extinct, or too small to meet 

our selection criteria, and are not 

proposed for critical habitat. Each of 

these units provide habitat that have the 

features essential to the conservation of 

the species; they each support the 

largest remaining populations in this 

portion of their range; are located in 

relatively close proximity to one 

another; have increasing potential for 

cross pollination and increased 

reproductive success; and there is 

surrounding prairie habitat available for 

population expansion. 

Unit 3 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–3) 

Unit KL–3 consists of approximately 

51 ac (20.6 ha) of private lands within 

Yamhill County. The Lupinus 

sulphureus ssp. kincaidii population is 

comprised of several populations 

scattered along the east and west sides 

of Gopher Valley Road near its 

intersection with Dupee Road. Yamhill 

County is responsible for roadside 

maintenance activities along Gopher 

Valley Road, which may adversely 

impact this population of L. sulphureus 

ssp. kincaidii. The largest distance 

separating lupine populations is 

approximately 0.12 mi (0.2 km). This 

population is threatened by the 

presence of invasive species; the 

relatively small, isolated nature of the 

population; and impacts associated with 

roadside maintenance activities. The 

Fender’s blue butterfly uses L. 

sulphureus ssp. kincaidii at this site as 

a primary host plant, and 100 percent of 

Unit KL–3 is included in Unit FBB–2. 

The prairie habitat within KL–3 

should be managed to allow for growth 

and expansion of this relatively small 

population. Increasing the number of 

Lupinus sulphureus ssp. kincaidii 

patches in close proximity to one 

another will increase the chances for 

outcrossing pollination, which is 

essential to the conservation of this 

species. Because of the limited 

availability of supporting prairie habitat, 

this population will need to function 

with other populations as a larger, more 

viable metapopulation in order to 

persist over the long term. This prairie 

habitat should be actively managed in 

order to maintain the short-grass prairie 

stature essential for the conservation of 

L. sulphureus ssp. kincaidii and provide 

opportunity for population growth and 

expansion. One peer reviewer provided 

us with additional information that 

there is prairie habitat supporting a 

‘‘large area of L. sulphureus ssp. 

kincaidii’’ within Deer Creek Park, 

which is owned by Yamhill County. 

Additionally, the peer reviewer noted 

that the lupine patch has been growing 

and expanding rapidly over the last few 

years. Although not included within the 

critical habitat designation (see 

comment/response #1), this population 

of L. sulphureus ssp. kincaidii 

substantially contributes to the 

metapopulation in this portion of the 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63889 

species range and increases the overall 

viability of this metapopulation. 

Unit 4 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–4A and 4B) 

Unit KL–4A and 4B consists of 

approximately 68.6 ac (27.8 ha) of 

private lands in Yamhill County and is 

located west of Muddy Valley Road and 

south of Eagle Point Road. The Lupinus 

sulphureus ssp. kincaidii populations 

are relatively small and scattered across 

this large, contiguous prairie remnant. 

The L. sulphureus ssp. kincaidii 

population within this unit boundary is 

one of only a few populations supported 

by extensive areas of the short-grass 

prairie necessary for population growth 

and expansion. Unit KL–4 (KL–4A and 

4B) provides habitat with features 

essential for the continued persistence 

of this core population, and, together 

with the habitat included in Unit KL–

3, these areas are fundamental to the 

continued persistence of a viable 

metapopulation in this portion of the 

species’ range. 

Units 5 and 6 of Lupinus sulphureus 

ssp. kincaidii (Unit KL–5 and KL–6) 

Units KL–5 and KL–6 are both 

primarily State-owned lands managed 

by the ODOT. Each unit supports 

populations of Lupinus sulphureus ssp. 

kincaidii in this portion of the species’

range that collectively function as a 

larger metapopulation. These units are 

both relatively small, but are two of the 

largest remaining populations in this 

portion of the species’ range. In 

addition, they are located approximately 

5 mi (8 km) from one another, within 

the estimated pollinator distance, and 

therefore may be functioning as a larger, 

more viable metapopulation. Since 

these populations are just within the 

pollinator maximum dispersal distance, 

cross pollination between habitat 

patches is likely a rare event. Active 

management will likely be necessary to 

both enhance these populations and 

identify opportunities to increase 

pollinator connectivity between units. 

At this time, we do not have enough 

information to identify additional 

potential habitat for population 

expansion, which will likely be 

necessary for these populations to 

regularly function as a larger 

metapopulation. Although there are 

other small, mostly roadside 

populations recorded within the 

estimated 5 mi (8 km) pollinator 

distance, most are highly degraded, 

presumed extirpated, or too small to 

meet our selection criteria and not 

expected to contribute towards the longterm persistence of this species. KL–5 

and KL–6 provide habitat with the 

features essential to the conservation of 

the species; they support the largest 

remaining populations in this portion of 

their range; are located in relatively 

close proximity to one another, 

increasing potential for cross pollination 

and increased reproductive success; and 

have surrounding prairie habitat 

available for population expansion. 

Unit 5 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–5) 

Unit KL–5 encompasses 

approximately 1.7 ac (0.7 ha) of ODOT 

land in southern Yamhill County and is 

located south of State Highway 18, east 

of Ballston Road, and approximately 0.6 

mi (1 km) south of the Yamhill River. 

Although the overall prairie remnant 

supporting the population is small, the 

population of Lupinus sulphureus ssp. 

kincaidii it supports a substantial lupine 

popultion, with over a 1,000 individuals 

reported to occupy the unit (Gisler in 

litt., p.1 ). Special management should 

focus on establishing or managing 

prairie habitat between KL–5 and KL–6 

to allow for growth and expansion of the 

overall metapopulation. Severns (2003a, 

p. 227) indicates that the stepping-stone 

reserve design recommended for the 

conservation of the Fender’s blue 

butterfly will also benefit L. sulphureus 

ssp. kincaidii populations. Increasing 

the number of lupine patches in close 

proximity to one another will likely 

increase the chances for outcrossing 

pollination, which will increase longterm viability of the metapopulation. 

Unit KL–5 provides the habitat 

containing the features essential for the 

continued persistence of this core 

population and, together with the 

habitat included in Unit KL–6, is 

fundamental to the continued 

persistence of a functioning 

metapopulation in this portion of the 

species’ range. 

Unit 6 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–6) 

Unit KL–6 encompasses 

approximately 3.6 ac (1.5 ha) of 

primarily ODOT land in northern Polk 

County. The Lupinus sulphureus ssp. 

kincaidii population occurs in two 

patches scattered along the northeast 

and southwest sides of Highway 22, 

near the intersection with Mill Creek 

Road. The Fender’s blue butterfly uses 

L. sulphureus ssp. kincaidii at this site 

as a primary host plant, and 100 percent 

of Unit KL–6 is included in Unit FBB–

3. Additionally, a small population of 

Erigeron decumbens var. decumbens 

occurs at this site. Hammond (2004, p. 

10) documented that invasive grasses 

and shrubs have suppressed the L. 

sulphureus ssp. kincaidii and E. 

decumbens var. decumbens populations 

occupying this prairie remnant. 

Although Unit KL–6 has limited 

available prairie habitat directly 

adjacent to the area currently supporting 

the species, mowing activities 

implemented by ODOT in 2000 resulted 

in an increase of Lupinus sulphureus 

ssp. kincaidii and Fender’s blue 

butterfly. This demonstrates that 

appropriate management of this site 

provides an opportunity for population 

growth and expansion. Unit KL–6 

provides habitat containing the features 

essential for the continued persistence 

of the core population, strengthens this 

core reserve area together with Unit KL–

5, and is fundamental to the continued 

persistence of a functioning 

metapopulation in this portion of the 

species’ range. It is likely that other 

populations occur in the near vicinity 

because the surrounding area is fairly 

undeveloped and much of this land has 

never been surveyed for L. sulphureus 

ssp. kincaidii. 

Unit 7 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–7) 

Unit KL–7 consists of approximately 

12.3 ac (5 ha) of private lands in central 

Polk County. This unit is located near 

the junction of Highway 223 and 

Oakdale Avenue, and largely falls 

within the City of Dallas urban-growth 

boundary. The Fender’s blue butterfly 

uses Lupinus sulphureus ssp. kincaidii 

at this site as a primary host plant, and 

100 percent of Unit KL–7 is included in 

Unit FBB–5. This butterfly population 

was monitored consistently between 

1993 and 1997, but not again until May 

2004. During the May 2004 field season, 

we met with the private landowner who 

owns one of the land parcels currently 

supporting the population of L. 

sulphureus ssp. kincaidii occurring 

within this unit boundary. We were able 

to document the extent of the area 

supporting the PCEs across the 

landscape and determined that a 

significant portion of the area 

historically supporting L. sulphureus 

ssp. kincaidii and Fender’s blue 

butterfly populations has been 

developed into residential lots. 

Hammond (2004, p. 12) documented the 

removal of several acres of habitat over 

the last 10 years that had historically 

supported this population and these 

areas are not included within the 

critical habitat unit. This population is 

threatened by the presence of invasive 

species and the impacts associated with 

the encroachment of urban 

development. However, ongoing habitat 

management activities should reduce 

the threats of invasive species and 

provide opportunity for population

growth and expansion. The landowner 

we met with in 2004 has entered into a 

Partners for Fish and Wildlife 

Agreement (USFWS 2004c) and, in 

cooperation with Refuge staff, has 

agreed to manage the portion of the 

Fender’s blue butterfly and L. 

sulphureus ssp. kincaidii habitat 

occurring on his property. 

The area identified within the 

boundaries of KL–7 includes the 

features essential to the conservation of 

this core population in this portion of 

the species’ range. Because of the 

limited availability of supporting prairie 

habitat, this population will likely need 

to function with other populations as a 

larger, viable metapopulation in order 

for the species to persist over the long 

term. At this time, we do not have 

enough information to specifically 

identify which surrounding areas 

supporting the PCEs will likely be 

necessary for the long-term viability of 

this larger metapopulation. The open 

areas to the south support roadside 

prairie remnants historically occupied 

by Lupinus sulphureus ssp. kincaidii 

populations that have been extirpated 

over the last 10 years (Hammond 2004, 

p. 12, 13). 

Units 8, 9, and 10 of Lupinus 

sulphureus ssp. kincaidii (Units KL–8, 

KL–9, and KL–10) 

Units 8, 9, and 10 each support a 

Lupinus sulphureus ssp. kincaidii 

population that collectively, may 

function as a larger metapopulation. 

These units are located approximately 

3.7 mi (6 km) apart and may, at least 

occasionally, be cross-pollinated by 

insects. Active management will likely 

be necessary to both enhance these 

populations and identify opportunities 

to increase pollinator connectivity 

between units. Each of these units 

contain habitat that have the features 

essential to the conservation of the 

species; they each support a relatively 

large population; they are located in 

relatively close proximity to one 

another, thus increasing potential for 

cross-pollination and increased 

reproductive success; and there is 

surrounding prairie habitat available for 

population expansion. At this time, we 

do not have enough information to 

identify additional potential habitat for 

population expansion, which may be 

necessary for these populations to 

regularly function as a larger 

metapopulation. Although there are 

other small, mostly roadside 

populations recorded within the 

estimated 5 mi (8 km) pollinator 

distance, most are highly degraded, 

presumed extirpated, or too small to 

meet our selection criteria and not 

expected to contribute towards the longterm persistence; they are therefore not 

designated as critical habitat. 

Unit 8 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–8) 

Unit KL–8 consists of approximately 

11.5 ac (4.6 ha) of private and State 

lands in Benton County. This unit 

occurs in McDonald Forest located off 

Oak Creek Road and supports one of the 

highest quality remaining prairies. The 

Lupinus sulphureus ssp. kincaidii 

occupying this unit is the primary host 

plant of the Fender’s blue butterfly; this 

site is the second largest known 

Fender’s blue butterfly population, and 

100 percent of Unit KL–8 is included in 

Unit FBB–7. Approximately 14 percent 

of the lands supporting the PCEs within 

this unit occurs on Oregon State 

University lands, and the remaining 86 

percent occurs on private lands. The 

patches of L. sulphureus ssp. kincaidii 

occupying Unit KL–8 are scattered 

across a large contiguous prairie habitat, 

which is one of few occupied remnants 

occurring on valley hillsides. Unit KL–

8 provides high quality upland prairie 

habitat, including the short-grass stature 

necessary to maintain the openness of 

the habitat. However, this population is 

threatened by the encroachment of 

invasive grasses, particularly 

Brachypodium sylvaticum, and 

succession to forest. In narrow areas of 

the meadow, forest succession is 

particularly problematic because the 

tree encroachment could block-off 

portions of the habitat and reduce 

connectivity between lupine patches, 

thus decreasing the potential for 

successful outcrossing pollination. 

Although a management plan for this 

area has not been completed, the unit 

has been managed for several years to 

enhance populations of both the 

Fender’s blue butterfly and L. 

sulphureus ssp. kincaidii. 

Special management of these lands is 

needed . Unit KL–8 provides habitat 

that has the features essential to the 

conservation of this species; it has one 

of the largest remaining contiguous 

prairie patches supporting a large 

population of Lupinus sulphureus ssp. 

kincaidii; there is surrounding prairie 

habitat available for population 

expansion; and this subpopulation 

increases the long-term viability of 

neighboring populations by contributing 

individuals to the overall 

metapopulation. 

Unit 9 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–9) 

Unit KL–9 encompasses 

approximately 171.6 ac (69.4 ha) of 

private lands within Benton County. 

This unit is located in Wren, Oregon, 

between Kings Valley Highway, 

Cardwell Hill Road, and Blakesly Creek 

Road, approximately 2 mi (3.2 km) 

southwest of Unit KL–8. The Fender’s 

blue butterfly uses the Lupinus 

sulphureus ssp. kincaidii scattered 

across this unit as a primary host plant, 

and 100 percent of Unit KL–9 is 

included within Unit FBB–8. The 

estimated average distance between 

lupine patches in Unit KL–9 is 0.6 mi 

(1 km), providing excellent habitat 

conditions for outcrossing pollination 

between lupine individuals. 

This historic population was first 

documented in 1937 (Hammond 2004, 

p. 23), and new information has recently 

been identified about the distribution of 

the larger Lupinus sulphureus ssp. 

kincaidii metapopulation supported 

across this prairie remnant (Hammond 

2004, p. 23). A new patch of L. 

sulphureus ssp. kincaidii, also occupied 

by the Fender’s blue butterfly, has been 

documented within this prairie remnant 

and is located between the two 

populations that have been monitored 

annually (Hammond 2004, p. 23). The 

relatively ‘‘pristine’’ (Hammond 2004, p. 

23), large, prairie habitat included 

within this unit provides the short-grass 

prairie stature required for expansion of 

the L. sulphureus ssp. kincaidii 

population. The habitat identified in 

Unit KL–9 has the features essential to 

the conservation of this species; it is one 

of the largest remaining contiguous 

prairie patches supporting a large 

population of L. sulphureus ssp. 

kincaidii; it provides opportunity for 

population expansion; and this 

subpopulation increases the long-term 

viability of neighboring populations by 

contributing individuals to the overall 

metapopulation. 

Unit 10 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–10) 

Unit KL–10 consists of approximately 

17.9 ac (7.2 ha) of private lands within 

Benton County and is located north of 

Philomath, with the habitat occurring 

primarily to the south of West Hills 

Road and to the west of 19th Street. This 

unit provides the features essential to 

the Lupinus sulphureus ssp. kincaidii 

population that serves as the primary 

host plant for a large population of 

Fender’s blue butterfly. All of the area 

within Unit KL–10 is included in Unit 

FBB–9. The Greenbelt Land Trust 

recently obtained a conservation 

easement for the habitat and began 

managing prairie to enhance the areas 

supporting the features essential to the 

conservation of both the L. sulphureus 

ssp. kincaidii and Fender’s blue 

butterfly populations.

Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63891 

Threats to this site include 

encroachment of invasive species, trees, 

and shrubs. A small portion of Unit KL–

10 is located along West Hills Road and 

is impacted by roadside maintenance 

activities. The long-term viability of this 

unit will depend on continued active 

management that maintains the shortgrass prairie habitat within this unit and 

provides opportunity to expand the 

existing population of Lupinus 

sulphureus ssp. kincaidii. The habitat 

identified in Unit KL–10 has the 

features essential to the conservation of 

this species; it is one of the highest 

quality remaining prairie patches 

supporting L. sulphureus ssp. kincaidii; 

there is surrounding prairie habitat 

available for population expansion; and 

this subpopulation increases the longterm viability of neighboring 

populations by contributing individuals 

to the overall metapopulation. 

Units 11 and 12 of Lupinus sulphureus 

ssp. kincaidii (Units KL–11 and KL–12) 

Units KL–11 (KL–11A, 11B, 11C, 11D, 

and 11E) and KL–12 (KL–12A, 12B, 12C, 

12D, and 12E) collectively represent a 

series of upland habitat patches 

distributed across West Eugene 

interspersed with wet prairie habitat 

patches. This type of extensive network 

of wetland and upland prairie does not 

occur anywhere else in the Willamette 

Valley. Units KL–12A, 12B and 12C 

collectively provide a series of steppingstone habitat patches between Lupinus 

sulphureus ssp. kincaidii populations 

supported by habitat within KL–12D 

and KL–12E and those populations 

occupying Unit KL–11. Increasing the 

number of lupine patches in close 

proximity to one another increases the 

chances for outcrossing pollination, 

which is required for successful 

reproduction. Both of these units 

contain habitat with the features 

essential to the conservation of the 

species; they each support the largest 

remaining L. sulphureus ssp. kincaidii 

populations in this portion of their 

range; they are located in relatively 

close proximity to one another, thus 

increasing potential for cross pollination 

and increased reproductive success; and 

there is substantial surrounding prairie 

habitat available for population 

expansion. Although there are other 

small, mostly roadside populations 

recorded within the estimated 5 mi (8 

km) pollinator distance, most are highly 

degraded, presumed extinct, or too 

small to meet our selection criteria, and 

therefore are not designated as critical 

habitat. 

Unit 11 of Lupinus sulphureus ssp. 

kincaidis (Unit KL–11A, 11B, 11C, 11D, 

and 11E) 

Unit KL–11 encompasses 

approximately 64.6 ac (26.2 ha) of 

prairie habitat distributed across Federal 

and private lands in Lane County. This 

unit is located in West Eugene, near the 

Fern Ridge Reservoir, just south of 

Clearlake Road, and on both the east 

and west sides of Fir Butte Road. The 

area included in Units KL–11A, 11B, 

11C, 11D, and 11E, collectively 

represent areas containing habitat with 

the features essential to the conservation 

of a currently functioning Lupinus 

sulphureus ssp. kincaidii 

metapopulation. The Fender’s blue 

butterfly uses L. sulphureus ssp. 

kincaidii within this unit as a primary 

host plant and 100 percent of Unit KL–

11 is included in Unit FBB–10. 

The habitat within Unit KL–11 

primarily occurs on Federal land 

managed by the BLM and Army Corp of 

Engineers, with 12 percent occurring on 

private land. The Lupinus sulphureus 

ssp. kincaidii populations occurring in 

KL–11A, 11B, 11C, and 11D are 

scattered across the area and form 

separate habitat patches that encircle 

the northeast edge of the Fern Ridge 

Reservoir. Although the Army Corp of 

Engineers actively manages most of the 

habitat supporting these populations, 

they all remain threatened by the 

presence of invasive grasses, 

predominantly Arrhenatherum elatius 

(tall oat grass), which limits the overall 

diversity of the site and the opportunity 

for population growth (Severns 2004, p. 

1). Lupinus sulphureus ssp. kincaidii 

occupying KL–11E is sparsely 

distributed across the entire subunit, 

making it difficult to identify separate L. 

sulphureus ssp. kincaidii patches. This 

subunit is severely threatened by the 

presence of exotic species, primarily 

Rubus armeniacus. Although Unit KL–

11 does not provide the highest quality 

habitat, it manages to support some of 

the largest remaining populations of L. 

sulphureus ssp. kincaidii in this portion 

of its range. The habitat included within 

Unit KL–11 contains the features 

essential for the continued persistence 

of this metapopulation. 

Unit 12 of Lupinus sulphureus ssp. 

kincaidii (Units KL–12A, 12B, 12C, 12D, 

and 12E): 

Unit KL–12 encompasses 

approximately 141.2 ac (57.1 ha) of 

prairie habitat distributed across Federal 

and private lands in Lane County. This 

unit is in west Eugene and located north 

of Bailey Hill Road and west of 

Bertelsen Road. This unit primarily 

occurs on lands owned by TNC and the 

BLM, with 4 percent occurring on 

private lands. The area included in KL–

12A, 12B, 12C, 12D, and 12E, 

collectively represents habitat with the 

features essential to the conservation of 

a functioning Lupinus sulphureus ssp. 

kincaidii metapopulation. The Fender’s 

blue butterfly uses the L. sulphureus 

ssp. kincaidii occupying this unit as a 

primary host plant, and 100 percent of 

Unit KL–12 is included in Units FBB–

11 and FBB–12. KL–12D and 12E are 

owned by TNC and support the highest 

quality upland prairie remaining in this 

portion of the species’ range. Lupinus 

sulphureus ssp. kincaidii is scattered 

across the prairie habitat in KL–12D and 

12E and forms four distinct lupine 

patches that are separated by an 

estimated maximum distance of 0.3 mi 

(0.5 km). The habitat is actively 

managed for L. sulphureus ssp. 

kincaidii, and the long-term goal for 

TNC’s lands is to eventually restore all 

available upland habitat and expand the 

population size. These units have the 

habitat containing the features essential 

to the conservation of this 

metapopulation; they provide the 

highest quality remaining habitat; 

support one of the largest remaining 

populations of L. sulphureus ssp. 

kincaidii; and provide habitat necessary 

for population growth. 

Unit KL–12C supports a relatively 

small population of Lupinus sulphureus 

ssp. kincaidii occurring on private land, 

just north of West 11th Avenue. Unit 

KL–12B also supports a relatively small 

population of L. sulphureus ssp. 

kincaidii occurring on lands owned and 

managed by the BLM that are located 

east of Green Hill Road and north of 

West 11th Avenue. During the proposed 

critical habitat mapping for KL–12B, an 

area adjacent to KL–12B was 

overlooked. The BLM has identified this 

area adjacent to KL–12B as suitable for 

expanding the existing population. This 

adjacent area provides opportunity for 

contributing to the conservation of L. 

sulphureus ssp. kincaidii by expanding 

the relatively small population and 

increasing the stability of the overall 

metapopulation in this area. Unit KL–

12A supports another relatively small 

population of L. sulphureus ssp. 

kincaidii occurring on land primarily 

owned and managed by the BLM and is 

located east of Green Hill Road and 

north of West 11th Avenue. Units KL–

12A, 12B, and 12C, collectively provide 

a series of stepping-stone habitat 

patches between the L. sulphureus ssp. 

kincaidii populations owned and 

managed by TNC and those populations 

occupying Unit KL–11.

Unit 13 of Lupinus sulphureus ssp. 

kincaidii (Unit KL–13) 

Unit KL–13 encompasses 

approximately 16.2 ac (6.6 ha) of private 

land in Lane County, and is located 

north of Powell Road and west of 

Coyote Creek. The prairie habitat 

included in this unit supports the 

southernmost population of Lupinus 

sulphureus ssp. kincaidii occurring in 

the Willamette Valley. The patches of L. 

sulphureus ssp. kincaidii are scattered 

across the available prairie habitat and 

include some of the densest stands of 

this plant observed (USFWS 2004a). 

Although there are no known 

occurrences of L. sulphureus ssp. 

kincaidii within pollinator distance of 

this population, it may be the healthiest 

population of this plant remaining. The 

habitat is threatened by the presence of 

invasive species such as Cytisus 

scoparius (Scotch broom), and the 

landowner manually removes the exotic 

species in order to maintain the 

conditions required for L. sulphureus 

ssp. kincaidii to persist. Unit KL–13 

provides the habitat that has the features 

that are essential to the conservation of 

the species; it supports possibly the 

largest remaining L. sulphureus ssp. 

kincaidii population; it is surrounded 

by high quality prairie that provides 

opportunity for population growth and 

expansion; and it is the southernmost 

population remaining in the Willamette 

Valley. 

Erigeron decumbens var. decumbens 

In total, we are designating 9 critical 

habitat units, each of which represents 

the habitat containing the features 

essential to the conservation of core 

populations across the range of the 

species. To simplify unit descriptions, 

we have grouped units that are within 

pollinator distance of one another, and 

may function as larger, connected 

metapopulations with proper 

management and restoration. 

There are very few extant populations 

of Erigeron decumbens var. decumbens 

documented outside of Eugene, Oregon. 

Due to limited distribution, Units WD–

1 to WD–5 are important for the 

continued persistence of E. decumbens 

var. decumbens across its current range. 

Unit 1 for Erigeron decumbens var. 

decumbens (Units WD–1A and 1B) 

Units WD–1A and 1B encompass 

approximately 41.2 ac (16.7 ha) of 

Federal land occurring in northern Polk 

County. This unit is located adjacent to 

Highway 22, approximately 5.6 mi (9 

km) northeast of the City of Dallas. 

There are two distinct populations (1A 

and 1B) located on the Baskett Slough 

National Wildlife Refuge, approximately 

0.9 mi (1.5 km) apart. Unit 1B is located 

on Baskett Butte summit and coexists 

with one of the largest remaining 

Fender’s blue butterfly populations. The 

prairie habitat supporting these Erigeron 

decumbens var. decumbens populations 

is currently being managed for the 

species. Units WD–1A and 1B contain 

habitat that has the features essential to 

the conservation of the species because 

they support the only remaining viable 

population of E. decumbens var. 

decumbens within Polk County, which 

represents the northernmost extent of 

the species’ range. Although there are 

other reported occurrences in the 

general vicinity, these sites do not meet 

the minimum patch size for our 

selection criteria, are highly degraded, 

or are believed to be extirpated sites 

and, therefore, are not critical habitat. 

Unit 2 for Erigeron decumbens var. 

decumbens (Unit WD–2) 

Unit WD–2 encompasses 

approximately 12.2 ac (4.9 ha) of private 

land occurring in southern Marion 

County. This unit occurs south of SE 

Triumph Road and east of SE 

Boedigheimer Road, and supports the 

largest remaining Erigeron decumbens 

var. decumbens population in Marion 

County. Although this unit is privately 

owned, the Bonneville Power 

Administration holds an easement to 

maintain the powerline right-of-way 

that bisects the unit. This E. decumbens 

var. decumbens population is supported 

in a relatively large patch of high quality 

prairie that includes a diverse mix of 

prairie indicator species. Threats to the 

site include the presence of invasive 

species, population isolation including 

risk of inbreeding depression, and 

maintenance activities in the powerline 

right-of-way. Unit WD–2 contains 

habitat that has the features essential to 

the conservation of the species; it 

supports the only core population in 

Marion County; and it supports a large 

population in high quality habitat with 

the opportunity to increase population 

size and maintain a viable population. 

Although there are other reported 

occurrences in the general vicinity, 

those sites do not meet the minimum 

patch size as identified by our selection 

criteria, are highly degraded, or are 

believed to be extirpated sites and, 

therefore, are not critical habitat. 

Unit 3 for Erigeron decumbens var. 

decumbens (Units WD–3A, 3B, and 3C) 

Unit WD–3 encompasses 

approximately 58.3 ac (23.6 ha) of 

private land occurring within northern 

Linn County. This site is located north 

of SE Kingston Lyons Drive and on both 

the east and west sides of Huntly Road, 

and is primarily owned by TNC. This 

population of Erigeron decumbens var. 

decumbens occurs in a relatively large 

patch of high quality prairie that 

supports a diverse mix of prairie 

indicator species. The E. decumbens 

var. decumbens populations are 

distributed across the prairie remnant in 

three distinct habitat patches (WD–3A, 

3B, and 3C). Threats to this site include 

the presence of invasive species, and 

population isolation including risk of 

inbreeding depression. TNC is managing 

the habitat supporting this population to 

allow for population expansion and 

reduce the distance between E. 

decumbens var. decumbens plant 

patches. Unit WD–3 contains the habitat 

that has the features essential to the 

conservation of the species; it supports 

the only remaining viable population 

within all of Linn County; supports a 

large population in high quality habitat 

with the opportunity to increase 

population size and establish a viable 

population; and represents the 

easternmost extent of the species’ range. 

Although there are other reported 

occurrences in the general vicinity, 

those sites do not meet the minimum 

patch size for our selection criteria, are 

highly degraded, are roadside without 

potential for population expansion, or 

are believed to be extirpated sites and, 

therefore, are not critical habitat. 

Unit 4 for Erigeron decumbens var. 

decumbens (Units WD–4A and 4B) 

Unit WD–4 encompasses 

approximately 9.3 ac (3.8 ha) of private 

and City of Corvallis land occurring in 

Benton County. This unit is located 

north of SW Reservoir Avenue and 

south of NW Oak Creek Drive. 

Approximately half of the habitat within 

this unit is located on City of Corvallis 

land and half on private land. The 

habitat supporting this population of 

Erigeron decumbens var. decumbens 

occurs in two distinct habitat patches 

(WD–4A and 4B) approximately 0.6 mi 

(1 km) apart. A portion of the E. 

decumbens var. decumbens population 

occupying this unit occurs along a 

hiking trail located on private land with 

a City of Corvallis access easement. 

Threats to this unit include woody 

encroachment, trail maintenance, and 

the small size and isolated nature of the 

population. There are only two other 

reported occurrences in Benton County: 

one population in Unit WD–5 and a 

second population encompassing 300 

square ft. (28 square m) within the 

boundary of the William Finley 

National Wildlife Refuge. 

Although the Erigeron decumbens 

var. decumbens population occupying 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63893 

this unit is relatively small, it is one of 

the largest remaining populations in this 

portion of the species’ range and is 

supported by a large habitat patch with 

a moderate diversity of indicator 

species. Unit WD–4 contains habitat 

that has the features essential to the 

conservation of the species; it supports 

one of three remaining populations in 

Benton County; and has a moderate size 

population with enough available 

habitat to provide for population growth 

and expansion. Unit WD–4 supports a 

core population fundamental to the 

continued persistence of the species in 

this portion of its current range. 

Unit 5 for Erigeron decumbens var. 

decumbens (Unit WD–5) 

Unit WD–5 consists of approximately 

38.5 ac (15.6 ha) of private land, south 

of Corvallis, in Benton County. This 

unit is located along Muddy Creek, just 

to the west of Cutler Lane. The 

Greenbelt Land Trust is currently 

working with the landowner to place a 

conservation easement on the property, 

and, in cooperation with the Service, 

they plan to restore and enhance native 

habitats within the unit. Unit WD–5 

contains the habitat that has the features 

essential to the conservation of the 

species; it supports the largest 

population of Erigeron decumbens var. 

decumbens in Benton County; includes 

substantial habitat for population 

expansion; and supports the core 

population fundamental to the 

continued persistence of the species in 

this portion of its current range. 

Units 6, 7, 8, and 9 for Erigeron 

decumbens var. decumbens (Units WD–

6, WD–7, WD–8, and WD–9) 

Units WD–6, WD–7, WD–8, and WD–

9 occur in West Eugene, Oregon, and 

collectively represent the largest, mostconnected, functional network of 

suitable prairie habitat for Erigeron 

decumbens var. decumbens. Units WD–

6, WD–7, WD–8, and WD–9 contain the 

habitat that has the features essential to 

the conservation of this species; they 

each support stable populations and, 

collectively, these units support the 

only large metapopulation of E. 

decumbens var. decumbens. 

Because units WD–6, WD–7, WD–8, 

and WD–9 support the only large 

metapopulation of E. decumbens var. 

decumbens across its current range, the 

habitat supporting these populations 

provide the highest probability for longterm persistence of the species. Any 

reduction of available habitat will create 

more edge effect, increase habitat 

fragmentation, reduce outcrossing 

pollination potential, and further reduce 

population viability. Units WD–6, WD–

7, WD–8, and WD–9 are threatened to 

varying degrees by the encroachment of 

invasive species and active management 

will be necessary to ensure the longterm persistence of this large 

metapopulation. Additionally, habitat 

enhancement may be necessary to 

expand populations across this 

metapopulation and further increase 

connectivity. Although there are other 

reported occurrences of Erigeron 

decumbens var. decumbens in the 

general vicinity, those sites do not meet 

the minimum patch size for our 

selection criteria, or are highly 

degraded, and are therefore not critical 

habitat. 

Unit 6 for Erigeron decumbens var. 

decumbens (Units WD–6A, 6B, 6C, and 

6D) 

Unit WD–6 encompasses 

approximately 85.4 ac (34.6 ha) of 

critical habitat, with an estimated 89 

percent on Federal land and 11 percent 

occurring on private land. This unit is 

located in Eugene, along Ken Neilsen 

Road and West 11th Avenue. The 

federally owned land includes both 

BLM and Army Corp of Engineers lands. 

WD–6A supports one of the largest 

remaining populations of Erigeron 

decumbens var. decumbens, occurs on 

Army Corp of Engineers lands, and is 

located on the northwestern edge of this 

relatively large metapopulation. 

Unit WD–6 contains habitat that has 

the features essential to the conservation 

of this species; it supports a stable 

population and has an important role in 

support of the only large 

metapopulation of E. decumbens var. 

decumbens. 

Unit 7 for Erigeron decumbens var. 

decumbens (Units WD–7A and WD–7B) 

Unit WD–7A consists of 

approximately 22.3 ac (9 ha) of critical 

habitat, primarily on Federal land, with 

2 percent occurring on private land. 

WD–7A is located to the west of Green 

Hill Road and to the north of West 11th 

Avenue, and is managed by the Army 

Corp of Engineers. The habitat included 

within this unit boundary supports a 

moderately sized Erigeron decumbens 

var. decumbens population with habitat 

available for population expansion. 

Subunit WD–7B encompasses 

approximately 143.4 ac (58 ha) of 

primarily Federal land with an 

estimated 22 percent occurring on 

private land and an estimated 4 percent 

occurring on State land. This subunit is 

located near the intersection of Green 

Hill Road and West 11th Avenue. 

Erigeron decumbens var. decumbens is 

patchily distributed across the subunit 

with enough supporting habitat to allow 

for population growth. The E. 

decumbens var. decumbens populations 

supported by WD–7A and 7B are less 

than 0.6 miles (1 km) from the nearest 

neighboring population, providing for 

pollinator connectivity between habitat 

patches and increasing the potential for 

successful reproduction. 

Unit WD–7 contains habitat that has 

the features essential to the conservation 

of this species; it supports a stable 

population and has a role in support of 

the only large metapopulation of 

Erigeron decumbens var. decumbens. 

Unit 8 for Erigeron decumbens var. 

decumbens (Units WD–8A, WD–8B, 

WD–8C, WD–8D, and WD–8E) 

Subunits WD–8A and 8B consist of 

approximately 135.9 ac (55 ha) of 

Federal and private lands in West 

Eugene, Oregon. These subunits are 

located near the intersection of Willow 

Creek and West 18th Avenue. An 

estimated 45 percent of this area occurs 

on private land with approximately 55 

percent occurring on BLM land. The 

western half of subunit WD–8A 

includes high quality remaining wet 

prairie; the eastern portion of the site 

includes much lower quality habitat. 

WD–8A is a relatively large remnant 

prairie and provides excellent 

opportunity for population growth and 

expansion. WD–8B is located 

approximately 0.3 mi (0.5 km) directly 

east of WD–8A. This habitat patch is 

located directly north of TNC’s land, 

which is currently being managed for 

Erigeron decumbens var. decumbens. 

The location of these subunits, in close 

proximity to one another, increases the 

overall quality and viability of this 

metapopulation. 

Subunit WD–8C encompasses 

approximately 2.5 ac (1 ha) of private 

land located east of Wallis Street within 

the City of Eugene. This site supports a 

relatively small population of Erigeron 

decumbens var. decumbens on good 

quality wet prairie habitat with a 

diverse species composition. The site is 

located within 1.5 mi (2.5 km) of WD–

9B. Subunit WD–8C provides habitat for 

population growth and expansion. The 

E. decumbens var. decumbens plants 

occurring in this unit, Unit WD–6, and 

Unit WD–7 are all in close proximity to 

one another, thus increasing the 

potential for cross pollination between 

populations and reducing the risk of 

inbreeding depression. The primary 

threat to this habitat is that it is 

surrounded by development, reducing 

pollinator connectivity to the other 

populations. However, since this habitat 

is in close proximity to other 

populations, this E. decumbens var. 

decumbens site has a much higher 


rwilkins on PROD1PC63 with RULES_2
63894 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

chance of cross pollination than most 

remaining isolated populations. 

Subunits WD–8D and 8E consist of 

approximately 74.7 ac (30.3 ha) of 

prairie habitat that is owned by TNC. 

These subunits are located just south of 

West 18th Avenue along Willow Creek. 

These subunits include high quality 

prairie and support the second largest 

Erigeron decumbens var. decumbens 

population located in Eugene. These 

subunits provide sufficient habitat to 

support population growth and 

expansion, and are located less than 1.2 

mi (2 km) from neighboring E. 

decumbens var. decumbens 

populations. This large, connected, high 

quality habitat provides one of the core 

areas contributing towards the long-term 

conservation of Unit WD–8. 

Unit WD–8 contains habitat that has 

the features essential to the conservation 

of this species; it supports a stable 

population and has a role in support of 

the only large metapopulation of 

Erigeron decumbens var. decumbens. 

Unit 9 for Erigeron decumbens var. 

decumbens (Unit WD–9A, WD–9B, WD–

9C, WD–9D, and WD–9E) 

Subunit WD–9A encompasses an 

estimated 90 ac (36.4 ha) of private land 

and is located approximately 1.2 mi (2 

km) east of the intersection of Pine 

Grove Road and Crow Road. The 

Erigeron decumbens var. decumbens 

population occupying this unit is 

scattered in a few patches across this 

large prairie remnant. The habitat 

included within this unit includes high 

quality prairie with extensive habitat 

available to support population growth 

and expansion. This unit is located 

approximately 1.2 mi (2 km) north of 

the closest known E. decumbens var. 

decumbens population, increasing the 

long-term viability of both populations 

due to increased pollinator accessibility 

between plant patches. 

Subunits WD–9B and 9C consist of 

approximately 1 ac (0.4 ha) of private 

land and are located east of Pine Grove 

Road and south of Crow Road. Although 

this is a relatively small site, it is 

located on a high quality prairie 

remnant that supports a diversity of 

native composition. The Erigeron 

decumbens var. decumbens populations 

occupying these subunits occur in 

patches scattered around a stand of oak 

and Pinus ponderosa (Ponderosa pine). 

These subunits are located between 

WD–9A, WD–9D, and WD–9E, and 

increase the potential for outcrossing 

pollination of all Unit WD–9 

populations. 

Subunits WD–9D and WD–9E 

encompass approximately 3 ac (1.2 ha) 

of private land and are located north of 

Spencer Creek Road and east of Pine 

Grove Road. These subunits include 

high quality wet prairie with a highly 

diverse species composition and 

support hundreds of Erigeron 

decumbens var. decumbens plants. This 

population occurs at the southernmost 

extent of the species’ range, with Unit 

WD–9C located approximately 1.9 miles 

(3 km) to the north. 

Unit WD–9 contains habitat that has 

the features essential to the conservation 

of this species; it supports a stable 

population and has a role in support of 

the only large metapopulation of 

Erigeron decumbens var. decumbens. 

Effects of Critical Habitat Designation 

Section 7 Consultation 

Section 7 of the Act requires Federal 

agencies, including the Service, to 

ensure that actions they fund, authorize, 

or carry out are not likely to destroy or 

adversely modify critical habitat. In our 

regulations at 50 CFR 402.02, we define 

destruction or adverse modification as 

‘‘a direct or indirect alteration that 

appreciably diminishes the value of 

critical habitat for both the survival and 

recovery of a listed species. Such 

alterations include, but are not limited 

to, alterations adversely modifying any 

of those physical or biological features 

that were the basis for determining the 

habitat to be critical.’’ However, recent 

decisions by the 5th and 9th Circuit 

Court of Appeals have invalidated this 

definition. Pursuant to current national 

policy and the statutory provisions of 

the Act, destruction or adverse 

modification is determined on the basis 

of whether, with implementation of the 

proposed Federal action, the affected 

critical habitat would remain functional 

(or retain the current ability for the 

primary constituent elements to be 

functionally established) to serve the 

intended conservation role for the 

species. 

Section 7(a) of the Act requires 

Federal agencies, including the Service, 

to evaluate their actions with respect to 

any species that is proposed or listed as 

endangered or threatened and with 

respect to its critical habitat, if any is 

proposed or designated. Regulations 

implementing this interagency 

cooperation provision of the Act are 

codified at 50 CFR part 402. 

Section 7(a)(4) of the Act requires 

Federal agencies to confer with us on 

any action that is likely to jeopardize 

the continued existence of a proposed 

species or result in destruction or 

adverse modification of proposed 

critical habitat. This is a procedural 

requirement only. However, once a 

proposed species becomes listed, or 

proposed critical habitat is designated 

as final, the full prohibitions of section 

7(a)(2) apply to any Federal action. The 

primary utility of the conference 

procedures is to maximize the 

opportunity for a Federal agency to 

adequately consider proposed species 

and critical habitat and avoid potential 

delays in implementing their proposed 

action as a result of the section 7(a)(2) 

compliance process, should those 

species be listed or the critical habitat 

designated. 

Under conference procedures, the 

Service may provide advisory 

conservation recommendations to assist 

the agency in eliminating conflicts that 

may be caused by the proposed action. 

The Service may conduct either 

informal or formal conferences. Informal 

conferences are typically used if the 

proposed action is not likely to have any 

adverse effects to the proposed species 

or proposed critical habitat. Formal 

conferences are typically used when the 

Federal agency or the Service believes 

the proposed action is likely to cause 

adverse effects to proposed species or 

critical habitat, inclusive of those that 

may cause jeopardy or adverse 

modification. 

The results of an informal conference 

are typically transmitted in a conference 

report; while the results of a formal 

conference are typically transmitted in a 

conference opinion. Conference 

opinions on proposed critical habitat are 

typically prepared according to 50 CFR 

402.14, as if the proposed critical 

habitat were designated. We may adopt 

the conference opinion as the biological 

opinion when the critical habitat is 

designated, if no substantial new 

information or changes in the action 

alter the content of the opinion (see 50 

CFR 402.10(d)). As noted above, any 

conservation recommendations in a 

conference report or opinion are strictly 

advisory. 

If a species is listed or critical habitat 

is designated, section 7(a)(2) of the Act 

requires Federal agencies to ensure that 

activities they authorize, fund, or carry 

out are not likely to jeopardize the 

continued existence of such a species or 

to destroy or adversely modify its 

critical habitat. If a Federal action may 

affect a listed species or its critical 

habitat, the responsible Federal agency 

(action agency) must enter into 

consultation with us. As a result of this 

consultation, compliance with the 

requirements of section 7(a)(2) will be 

documented through the Service’s 

issuance of: (1) A concurrence letter for 

Federal actions that may affect, but are 

not likely to adversely affect, listed 

species or critical habitat; or (2) a 

biological opinion for Federal actions 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63895 

that may affect, but are likely to 

adversely affect, listed species or critical 

habitat. 

When we issue a biological opinion 

concluding that a project is likely to 

result in jeopardy to a listed species or 

the destruction or adverse modification 

of critical habitat, we also provide 

reasonable and prudent alternatives to 

the project, if any are identifiable. 

‘‘Reasonable and prudent alternatives’’

are defined at 50 CFR 402.02 as 

alternative actions identified during 

consultation that can be implemented in 

a manner consistent with the intended 

purpose of the action, that are consistent 

with the scope of the Federal agency’s 

legal authority and jurisdiction, that are 

economically and technologically 

feasible, and that the Director believes 

would avoid jeopardy to the listed 

species or destruction or adverse 

modification of critical habitat. 

Reasonable and prudent alternatives can 

vary from slight project modifications to 

extensive redesign or relocation of the 

project. Costs associated with 

implementing a reasonable and prudent 

alternative are similarly variable. 

Regulations at 50 CFR 402.16 require 

Federal agencies to reinitiate 

consultation on previously reviewed 

actions in instances where a new 

species is listed or critical habitat is 

subsequently designated that may be 

affected and the Federal agency has 

retained discretionary involvement or 

control over the action or such 

discretionary involvement or control is 

authorized by law. Consequently, some 

Federal agencies may request 

reinitiation of consultation with us on 

actions for which formal consultation 

has been completed, if those actions 

may affect subsequently listed species 

or designated critical habitat or 

adversely modify or destroy proposed 

critical habitat. 

Federal activities that may affect the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens or their 

designated critical habitat will require 

section 7 consultation under the Act. 

Activities on State, tribal, local or 

private lands requiring a Federal permit 

(such as a permit from the Corps under 

section 404 of the Clean Water Act or a 

permit under section 10(a)(1)(B) of the 

Act from the Service) or involving some 

other Federal action (such as funding 

from the Federal Highway 

Administration, Federal Aviation 

Administration, or the Federal 

Emergency Management Agency) will 

also be subject to the section 7 

consultation process. Federal actions 

not affecting listed species or critical 

habitat, and actions on State, tribal, 

local, or private lands that are not 

federally-funded, authorized, or 

permitted, do not require section 7 

consultations. 

Application of the Jeopardy and 

Adverse Modification Standards for 

Actions Involving Effects to the Fender’s 

blue butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens and Their Critical Habitat 

Jeopardy Standard 

Prior to and following designation of 

critical habitat, the Service has applied 

an analytical framework for Fender’s 

blue butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens jeopardy analyses that relies 

heavily on the importance of core area 

populations to the survival and recovery 

of the Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens. The section 

7(a)(2) analysis is focused not only on 

these populations but also on the habitat 

conditions necessary to support them. 

The jeopardy analysis usually 

expresses the survival and recovery 

needs of the Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens in 

a qualitative fashion without making 

distinctions between what is necessary 

for survival and what is necessary for 

recovery. Generally, if a proposed 

Federal action is incompatible with the 

viability of the affected core area 

population(s), inclusive of associated 

habitat conditions, a jeopardy finding is 

considered to be warranted, because of 

the relationship of each core area 

population to the survival and recovery 

of the species as a whole. 

Adverse Modification Standard 

The analytical framework described 

in the Director’s December 9, 2004, 

memorandum is used to complete 

section 7(a)(2) analyses for Federal 

actions affecting Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens 

critical habitat. The key factor related to 

the adverse modification determination 

is whether, with implementation of the 

proposed Federal action, the affected 

critical habitat would remain functional 

(or retain the current ability for the 

primary constituent elements to be 

functionally established) to serve the 

intended conservation role for the 

species. Generally, the conservation role 

of Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens critical 

habitat units is to support viable core 

area populations. 

Section 4(b)(8) of the Act requires us 

to briefly evaluate and describe in any 

proposed or final regulation that 

designates critical habitat those 

activities involving a Federal action that 

may destroy or adversely modify such 

habitat, or that may be affected by such 

designation. Activities that may destroy 

or adversely modify critical habitat may 

also jeopardize the continued existence 

of the species. 

Activities that may destroy or 

adversely modify critical habitat are 

those that alter the PCEs to an extent 

that the conservation value of critical 

habitat for the Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, and 

Erigeron decumbens var. decumbens is 

appreciably reduced. Activities that, 

when carried out, funded, or authorized 

by a Federal agency, may affect critical 

habitat and therefore result in 

consultation for the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, or Erigeron decumbens var. 

decumbens include, but are not limited 

to: 

(1) Actions that would further 

degrade, or destroy prairie habitat 

supporting populations of Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, or Erigeron decumbens var. 

decumbens. Such activities could 

include, but are not limited to, the 

removal or destruction of prairie habitat 

by grading, leveling, plowing, mowing, 

burning, operation of motorized 

equipment, herbicide spraying, or 

intensive grazing. These activities could 

eliminate or reduce the habitat 

necessary for Fender’s blue butterfly by 

removing the host plant essential for 

reproduction and larval feeding, as well 

as adult nectaring plants. Additionally, 

removal or destruction of habitat further 

isolates populations and increases the 

risk of inbreeding depression. 

Implementation of these activities in 

prairie habitat supporting L. sulphureus 

ssp. kincaidii or E. decumbens var. 

decumbens could directly eliminate 

individuals and eliminate the potential 

for essential population growth and 

expansion in the available ‘‘open 

spaces’’ of native short-grass prairie 

habitat. 

(2) Actions that further isolate or 

reduce genetic interchange among 

populations of Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens 

from other extant locations within a unit 

or between subunits. Such activities 

could include, but are not limited to, the 

construction or expansion of roads, 

houses, buildings, or infrastructure that 

limit dispersal of the Fender’s blue 

butterfly between lupine patches, and 

limit the dispersal of plant pollinators 


rwilkins on PROD1PC63 with RULES_2
63896 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

between L. sulphureus ssp. kincaidii 

and E. decumbens var. decumbens 

populations. These activities reduce the 

opportunity for population growth and 

decrease genetic diversity by limiting 

normal breeding behaviors. 

We consider all of the units 

designated as critical habitat, as well as 

those that have been excluded, to 

contain features essential to the 

conservation of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, or Erigeron decumbens var. 

decumbens. All critical habitat units are 

within the geographic ranges of these 

species, and all were occupied by these 

species at the time of listing. All units 

are likely to be used by Fender’s blue 

butterfly, L. sulphureus ssp. kincaidii, or 

E. decumbens var. decumbens to carry 

out important life history functions. 

Federal agencies already consult with us 

on activities in areas currently occupied 

by Fender’s blue butterfly, L. sulphureus 

ssp. kincaidii, or E. decumbens var. 

decumbens, or if the species may be 

affected by the action, to ensure that 

their actions do not jeopardize the 

continued existence of the species. 

When analyzing whether the effects of 

those actions described above constitute 

adverse modification or destruction of 

critical habitat, the Service would 

determine whether the action precludes 

the ability of any given unit to provide 

the PCEs for which that unit was 

designated. In considering whether loss 

of the function of the PCEs contributes 

to adverse modification, we will 

consider the purpose for which any 

given unit was determined to be 

essential and designated as critical 

habitat. 

Federal agencies already consult with 

us on activities in areas currently 

occupied by the Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens or 

if the species may be affected by the 

action, to ensure that their actions do 

not jeopardize the continued existence 

of these species. 

Exclusions Under Section 4(b)(2) of the 

Act 

Section 3(5)(A) of the Act defines 

critical habitat as the specific areas 

within the geographic area occupied by 

the species on which are found those 

physical and biological features (i) 

essential to the conservation of the 

species, and (ii) which may require 

special management considerations or 

protection. Therefore, areas within the 

geographic area occupied by the species 

that do not contain the features essential 

to the conservation of the species are 

not, by definition, critical habitat. 

Similarly, areas within the geographic 

area occupied by the species that 

require no special management or 

protection also are not, by definition, 

critical habitat. 

There are multiple ways to provide 

management for species habitat. 

Statutory and regulatory frameworks 

that exist at a local level can provide 

such protection and management, as can 

lack of pressure for change, such as 

areas too remote for anthropogenic 

disturbance. Finally, State, local, or 

private management plans as well as 

management under Federal agencies 

jurisdictions can provide protection and 

management to avoid the need for 

designation of critical habitat. When we 

consider a plan to determine its 

adequacy in protecting habitat, we 

consider whether the plan, as a whole 

will provide the same level of protection 

that designation of critical habitat 

would provide. The plan need not lead 

to exactly the same result as a 

designation in every individual 

application, as long as the protection it 

provides is equivalent, overall. In 

making this determination, we examine 

whether the plan provides management, 

protection, or enhancement of the PCEs 

that is at least equivalent to that 

provided by a critical habitat 

designation, and whether there is a 

reasonable expectation that the 

management, protection, or 

enhancement actions will continue into 

the foreseeable future. Each review is 

particular to the species and the plan, 

and some plans may be adequate for 

some species and inadequate for others. 

Section 4(b)(2) of the Act states that 

critical habitat shall be designated, and 

revised, on the basis of the best 

available scientific data after taking into 

consideration the economic impact, 

national security impact, and any other 

relevant impact, of specifying any 

particular area as critical habitat. The 

Secretary may exclude an area from 

critical habitat if [s]he determines that 

the benefits of such exclusion outweigh 

the benefits of specifying such area as 

part of the critical habitat, unless [s]he 

determines, based on the best scientific 

data available, that the failure to 

designate such area as critical habitat 

will result in the extinction of the 

species. In making that determination, 

the Secretary is afforded broad 

discretion and the Congressional record 

is clear that in making a determination 

under the section the Secretary has 

discretion as to which factors and how 

much weight will be given to any factor. 

Under section 4(b)(2), in considering 

whether to exclude a particular area 

from the designation, we must identify 

the benefits of including the area in the 

designation, identify the benefits of 

excluding the area from the designation, 

determine whether the benefits of 

exclusion outweigh the benefits of 

inclusion. If an exclusion is 

contemplated, then we must determine 

whether excluding the area would result 

in the extinction of the species. In the 

following sections, we address a number 

of general issues that are relevant to the 

exclusions we considered. 

Conservation Partnerships on NonFederal Lands 

Most federally listed species in the 

United States will not recover without 

the cooperation of non-Federal 

landowners. More than 60 percent of the 

United States is privately owned 

(National Wilderness Institute 1995) and 

at least 80 percent of endangered or 

threatened species occur either partially 

or solely on private lands (Crouse et al. 

2002). Stein et al. (1995) found that only 

about 12 percent of listed species were 

found almost exclusively on Federal 

lands (i.e., 90–100 percent of their 

known occurrences restricted to Federal 

lands) and that 50 percent of federally 

listed species are not known to occur on 

Federal lands at all. 

Given the distribution of listed 

species with respect to land ownership, 

conservation of listed species in many 

parts of the United States is dependent 

upon working partnerships with a wide 

variety of entities and the voluntary 

cooperation of many non-federal 

landowners (Wilcove and Chen 1998; 

Crouse et al. 2002; James 2002). 

Building partnerships and promoting 

voluntary cooperation of landowners is 

essential to understanding the status of 

species on non-Federal lands and is 

necessary to implement recovery actions 

such as reintroducing listed species, 

habitat restoration, and habitat 

protection. 

Many non-Federal landowners derive 

satisfaction in contributing to 

endangered species recovery. The 

Service promotes these private-sector 

efforts through the Four Cs 

philosophy—conservation through 

communication, consultation, and 

cooperation. This philosophy is evident 

in Service programs such as HCPs, Safe 

Harbors, CCAs, CCAAs, and 

conservation challenge cost-share. Many 

private landowners, however, are wary 

of the possible consequences of 

encouraging endangered species to their 

property, and there is mounting 

evidence that some regulatory actions 

by the Federal government, while wellintentioned and required by law, can 

under certain circumstances have 

unintended negative consequences for 

the conservation of species on private 

lands (Wilcove et al. 1996; Bean 2002; 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63897 

Conner and Mathews 2002; James 2002; 

Koch 2002; Brook et al. 2003). Many 

landowners fear a decline in their 

property value due to real or perceived 

restrictions on land-use options where 

threatened or endangered species are 

found. Consequently, harboring 

endangered species is viewed by many 

landowners as a liability, resulting in 

anti-conservation incentives because 

maintaining habitats that harbor 

endangered species represents a risk to 

future economic opportunities (Main et 

al. 1999; Brook et al. 2003). 

The purpose of designating critical 

habitat is to contribute to the 

conservation of threatened and 

endangered species and the ecosystems 

upon which they depend. The outcome 

of the designation, triggering regulatory 

requirements for actions funded, 

authorized, or carried out by Federal 

agencies under section 7 of the Act, can 

sometimes be counterproductive to its 

intended purpose on non-Federal lands. 

According to some researchers, the 

designation of critical habitat on private 

lands significantly reduces the 

likelihood that landowners will support 

and carry out conservation actions 

(Main et al. 1999; Bean 2002; Brook et 

al. 2003). The magnitude of this 

negative outcome is greatly amplified in 

situations where active management 

measures (e.g., reintroduction, fire 

management, control of invasive 

species) are necessary for species 

conservation (Bean 2002). 

The Service believes that the 

judicious use of excluding specific areas 

of non-federally owned lands from 

critical habitat designations can 

contribute to species recovery and 

provide a superior level of conservation 

than critical habitat alone. For example, 

less than 17 percent of Hawaii is 

federally owned, but the state is home 

to more than 24 percent of all federally 

listed species, most of which will not 

recover without State and private 

landowner cooperation. On the island of 

Lanai, Castle and Cooke Resorts, LLC, 

which owns 99 percent of the island, 

entered into a conservation agreement 

with the Service. The conservation 

agreement provides conservation 

benefits to target species through 

management actions that remove threats 

(e.g., axis deer, mouflon sheep, rats, 

invasive nonnative plants) from the 

Lanaihale and East Lanai Regions. 

Specific management actions include 

fire control measures, nursery 

propagation of native flora (including 

the target species) and planting of such 

flora. These actions will significantly 

improve the habitat for all currently 

occurring species. Due to the low 

likelihood of a Federal nexus on the 

island we believe that the benefits of 

excluding the lands covered by the 

MOA exceeded the benefits of including 

them. As stated in the final critical 

habitat rule for endangered plants on 

the Island of Lanai: 

On Lanai, simply preventing ‘‘harmful 

activities’’ will not slow the extinction of 

listed plant species. Where consistent with 

the discretion provided by the Act, the 

Service believes it is necessary to implement 

policies that provide positive incentives to 

private landowners to voluntarily conserve 

natural resources and that remove or reduce 

disincentives to conservation. While the 

impact of providing these incentives may be 

modest in economic terms, they can be 

significant in terms of conservation benefits 

that can stem from the cooperation of the 

landowner. The continued participation of 

Castle and Cooke Resorts, LLC, in the 

existing Lanai Forest and Watershed 

Partnership and other voluntary conservation 

agreements will greatly enhance the Service’s 

ability to further the recovery of these 

endangered plants. 

The Department’s Four Cs 

philosophy—conservation through 

communication, consultation, and 

cooperation—is the foundation for 

developing the tools of conservation. 

These tools include conservation grants, 

funding for Partners for Fish and 

Wildlife Program, the Coastal Program, 

and cooperative-conservation challenge 

cost-share grants. Our Private 

Stewardship Grant program and 

Landowner Incentive Program provide 

assistance to private land owners in 

their voluntary efforts to protect 

threatened, imperiled, and endangered 

species, including the development and 

implementation of HCPs. 

Conservation agreements with nonFederal landowners (e.g., Habitat 

Conservation Plans (HCPs), contractual 

conservation agreements, easements, 

and stakeholder-negotiated State 

regulations) enhance species 

conservation by extending species 

protections beyond those available 

through section 7 consultations. In the 

past decade we have encouraged nonFederal landowners to enter into 

conservation agreements, based on a 

view that we can achieve greater species 

conservation on non-Federal land 

through such partnerships than we can 

through coercive methods (61 FR 63854; 

December 2, 1996). 

General Principles of Section 7 

Consultations Used in the 4(b)(2) 

Balancing Process 

The most direct, and potentially 

largest, regulatory benefit of critical 

habitat is that federally authorized, 

funded, or carried out activities require 

consultation pursuant to section 7 of the 

Act to ensure that they are not likely to 

destroy or adversely modify critical 

habitat. There are two limitations to this 

regulatory effect. First, it only applies 

where there is a Federal nexus—if there 

is no Federal nexus, designation itself 

does not restrict actions that destroy or 

adversely modify critical habitat. 

Second, it only limits destruction or 

adverse modification. By its nature, the 

prohibition on adverse modification is 

designed to ensure those areas that 

contain the physical and biological 

features essential to the conservation of 

the species or unoccupied areas that are 

essential to the conservation of the 

species are not eroded. Critical habitat 

designation alone, however, does not 

require specific steps toward recovery. 

Once consultation under section 7 of 

the Act is triggered, the process may 

conclude informally when the Service 

concurs in writing that the proposed 

Federal action is not likely to adversely 

affect the listed species or its critical 

habitat. However, if the Service 

determines through informal 

consultation that adverse impacts are 

likely to occur, then formal consultation 

would be initiated. Formal consultation 

concludes with a biological opinion 

issued by the Service on whether the 

proposed Federal action is likely to 

jeopardize the continued existence of a 

listed species or result in destruction or 

adverse modification of critical habitat, 

with separate analyses being made 

under both the jeopardy and the adverse 

modification standards. For critical 

habitat, a biological opinion that 

concludes in a determination of no 

destruction or adverse modification may 

contain discretionary conservation 

recommendations to minimize adverse 

effects to primary constituent elements, 

but it would not contain any mandatory 

reasonable and prudent measures or 

terms and conditions. Mandatory 

reasonable and prudent alternatives to 

the proposed Federal action would only 

be issued when the biological opinion 

results in a jeopardy or adverse 

modification conclusion. 

We also note that for 30 years prior to 

the Ninth Circuit Court’s decision in 

Gifford Pinchot Task Force v. U.S. Fish 

and Wildlife Service, 378 F.3d 1059 (9th 

Cir. 2004) the Service equated the 

jeopardy standard with the standard for 

destruction or adverse modification of 

critical habitat. The Court ruled that the 

Service could no longer equate the two 

standards and that adverse modification 

evaluations require consideration of 

impacts on the recovery of species. 

Thus, under the Gifford Pinchot 

decision, critical habitat designations 

may provide greater benefits to the 

recovery of a species. However, we 

believe the conservation achieved 


rwilkins on PROD1PC63 with RULES_2
63898 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

through implementing habitat 

conservation plans (HCPs) or other 

habitat management plans is typically 

greater than would be achieved through 

multiple site-by-site, project-by-project, 

section 7 consultations involving 

consideration of critical habitat. 

Management plans may commit 

resources to implement long-term 

management and protection to 

particular habitat for at least one and 

possibly other listed or sensitive 

species. Section 7 consultations only 

commit Federal agencies to prevent 

adverse modification to critical habitat 

caused by the particular project, and 

they are not committed to provide 

conservation or long-term benefits to 

areas not affected by the proposed 

project. Thus, any HCP or management 

plan which considers enhancement or 

recovery as the management standard 

will always provide as much or more 

benefit than a consultation for critical 

habitat designation conducted under the 

standards required by the Ninth Circuit 

in the Gifford Pinchot decision. 

The information provided in this 

section applies to all the discussions 

below that discuss the benefits of 

inclusion and exclusion of critical 

habitat in that it provides the framework 

for the consultation process. 

Educational Benefits of Critical Habitat 

A benefit of including lands in critical 

habitat is that the designation of critical 

habitat serves to educate landowners, 

State and local governments, and the 

public regarding the potential 

conservation value of an area. This 

helps focus and promote conservation 

efforts by other parties by clearly 

delineating areas of high conservation 

value for the Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens. In 

general the educational benefit of a 

critical habitat designation always 

exists, although in some cases it may be 

redundant with other educational 

effects. For example, HCPs have 

significant public input and may largely 

duplicate the educational benefit of a 

critical habitat designation. This benefit 

is closely related to a second, more 

indirect benefit: that designation of 

critical habitat would inform State 

agencies and local governments about 

areas that could be conserved under 

State laws or local ordinances. 

However, we believe that there would 

be little additional informational benefit 

gained from the designation of critical 

habitat for the exclusions we are making 

in this rule because these areas were 

included in the proposed rule as having 

habitat containing the features essential 

to the conservation of the species. 

Consequently, we believe that the 

informational benefits are already 

provided even though these areas are 

not designated as critical habitat. 

Additionally, the purpose normally 

served by the designation of informing 

State agencies and local governments 

about areas which would benefit from 

protection and enhancement of habitat 

for the Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens is already 

well established among State and local 

governments, and Federal agencies in 

those areas that we are excluding from 

critical habitat in this rule on the basis 

of other existing habitat management 

protections. 

The information provided in this 

section applies to all the discussions 

below that discuss the benefits of 

inclusion and exclusion of critical 

habitat. 

Relationship of Critical Habitat to 

Economic Impacts—Exclusions Under 

Section 4(b)(2) of the Act 

This section allows the Secretary to 

exclude areas from critical habitat for 

economic reasons if she determines that 

the benefits of such exclusion exceed 

the benefits of designating the area as 

critical habitat, unless the exclusion 

will result in the extinction of the 

species concerned. This is a 

discretionary authority Congress has 

provided to the Secretary with respect 

to critical habitat. Although economic 

and other impacts may not be 

considered when listing a species, 

Congress has expressly required their 

consideration when designating critical 

habitat. 

In general, we have considered in 

making the following exclusions that all 

of the costs and other impacts predicted 

in the economic analysis may not be 

avoided by excluding the area, due to 

the fact that all of the areas in question 

are currently occupied by the listed 

species and there will be requirements 

for consultation under Section 7 of the 

Act, or for permits under section 10 

(henceforth ‘‘consultation’’), for any take 

of these species, and other protections 

for the species exist elsewhere in the 

Act and under State and local laws and 

regulations. In conducting economic 

analyses, we are guided by the 10th 

Circuit Court of Appeal’s ruling in the 

New Mexico Cattle Growers Association 

case (248 F.3d at 1285), which directed 

us to consider all impacts, ‘‘regardless of 

whether those impacts are attributable 

co-extensively to other causes.’’ As 

explained in the analysis, due to 

possible overlapping regulatory schemes 

and other reasons, there are also some 

elements of the analysis that may 

overstate some costs. 

Conversely, the Ninth Circuit has 

recently ruled (‘‘Gifford Pinchot’’, 378 

F.3d at 1071) that the Service’s 

regulations defining ‘‘adverse 

modification’’ of critical habitat are 

invalid because they define adverse 

modification as affecting both survival 

and recovery of a species. The Court 

directed us to consider that 

determinations of adverse modification 

should be focused on impacts to 

recovery. While we have not yet 

proposed a new definition for public 

review and comment, compliance with 

the Court’s direction may result in 

additional costs associated with the 

designation of critical habitat 

(depending upon the outcome of the 

rulemaking). In light of the uncertainty 

concerning the regulatory definition of 

adverse modification, our current 

methodological approach to conducting 

economic analyses of our critical habitat 

designations is to consider all 

conservation-related costs. This 

approach would include costs related to 

sections 4, 7, 9, and 10 of the Act, and 

should encompass costs that would be 

considered and evaluated in light of the 

Gifford Pinchot ruling. 

In addition, we have received several 

credible comments on the economic 

analysis contending that it 

underestimates, perhaps significantly, 

the costs associated with this critical 

habitat designation. Both of these factors 

are a balancing consideration against the 

possibility that some of the costs shown 

in the economic analysis might be 

attributable to other factors, or are 

overly high, and so would not 

necessarily be avoided by excluding the 

area for which the costs are predicted 

from this critical habitat designation. 

We excluded lands owned by 

Mallonee Farms in Lewis County, 

Washington, private timber company 

lands in Douglas County, Oregon, and 

lands managed by the Bureau of Land 

Management (BLM) and U.S. Forest 

Service (Forest Service) in Douglas 

County, Oregon, from the final 

designation of critical habitat because 

we believe that they are appropriate for 

exclusion pursuant to the ‘‘other 

relevant factor’’ provisions of section 

4(b)(2). 

Mallonee Farms 

The proposed critical habitat for 

Lupinus sulphureus ssp. kincaidii in 

Lewis County, Washington, included 

land owned by Mallonee Farms (Farm) 

in the proposed critical habitat unit KL–

1A. This land is occupied by L. 

sulphureus ssp. kincaidii and supports 

the features essential to the conservation 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63899 

of the species. The landowners of the 

Farm have been working cooperatively 

with Federal and State agencies, 

including the Service, to implement 

recovery activities for L. sulphureus ssp. 

kincaidii on their property. In 

conjunction with the USDA Natural 

Resources Conservation Service, the 

landowners have developed a sitespecific farm management plan for L. 

sulphureus ssp. kincaidii on their 

property, including unit KL–1A. Active 

management, such as improved grazing 

and forage practices, invasive plant 

control, and periodic monitoring in 

cooperation with Federal and State 

agencies, will allow for an adaptive 

management approach within the unit 

to benefit L. sulphureus ssp. kincaidii. 

The landowners also recently allowed 

cooperating agencies access to their 

property to document additional lupine 

patches that were not known to 

previously occur on the property. The 

landowners have demonstrated the 

success of their voluntary management 

activities on the Farm by providing 

habitat conditions that support several 

flourishing L. sulphureus ssp. kincaidii 

patches. Without these protective 

management measures, all of which 

require voluntary landowner support 

and participation, the agricultural uses 

of this property would likely result in 

extirpation of L. sulphureus ssp. 

kincaidii from this area. 

If critical habitat designation in unit 

KL–1A reduces the likelihood that 

voluntary conservation activities will be 

carried out, and at the same time fails 

to confer a counterbalancing positive 

regulatory or educational benefit to the 

species, the benefits of excluding the 

unit from critical habitat outweigh the 

benefits of including it. 

(1) Benefits of Inclusion 

Critical habitat was proposed for 

Lupinus sulphureus ssp. kincaidii in 

unit KL–1A on land owned by Mallonee 

Farms. The primary direct benefit of 

inclusion of this land as critical habitat 

would result from the requirement 

under section 7 of the Act that Federal 

agencies consult with us to ensure that 

any proposed Federal actions do not 

destroy or adversely modify critical 

habitat. Without critical habitat, some 

site-specific projects might not trigger 

consultation requirements under the Act 

in areas where the species is not 

currently present; in contrast, Federal 

actions in areas occupied by listed 

species would still require consultation 

under section 7 of the Act. However, 

this unit is already occupied habitat for 

L. sulphureus ssp. kincaidii. Therefore, 

any Federal activities that may affect 

these areas will in all likelihood require 

section 7 consultation. 

Historically, we have conducted no 

formal or informal consultations under 

section 7 on unit KL–1A. As a result of 

the low level of previous Federal 

activity on this land, and considering 

that the likelihood of future Federal 

activities occurring on these lands 

would be minimal and associated with 

Federal funding for conservation 

activities, it is our opinion that there is 

likely to be a low number of future 

Federal activities that would negatively 

affect Lupinus sulphureus ssp. kincaidii 

habitat. Therefore, we anticipate little 

additional regulatory benefit from 

including unit KL–1A in critical habitat 

beyond what is already provided for by 

the existing section 7 nexus for areas 

occupied by the species. 

Another possible benefit from the 

designation of critical habitat is that 

designation can serve to educate the 

public regarding the potential 

conservation value of an area. By clearly 

delineating areas that are occupied by 

the species and informing the public 

that the area contains features essential 

to the conservation of the species, 

designation may focus and contribute to 

conservation efforts such as improved 

agricultural practices. Information 

provided to a wide public audience, 

including other parties engaged in 

conservation activities, about Lupinus 

sulphureus ssp. kincaidii and the 

features essential to its conservation as 

identified in unit KL–1A could have a 

positive conservation benefit. While we 

believe this educational outcome is 

important for the conservation of this 

species, it has already been achieved 

through existing management, 

education, and public outreach efforts 

carried out by the farm landowners and 

various Federal and State agencies. 

(2) Benefits of Exclusion 

Proactive voluntary conservation 

efforts are necessary to prevent the 

extinction and promote the recovery of 

Lupinus sulphureus ssp. kincaidii 

within its historic range. Consideration 

of this concern is especially important 

in areas where the species has been 

extirpated and its recovery may require 

access and permission for 

reintroduction efforts. For example, L. 

sulphureus ssp. kincaidii has been 

extirpated from many of its historical 

locations in Oregon and Washington 

and reestablishment is likely not 

possible without human assistance and 

non-Federal landowner cooperation. 

As described above, the landowners 

of the Farm have cooperated with 

Federal and State agencies to protect 

Lupinus sulphureus ssp. kincaidii 

patches on their property. They are 

willing to conduct voluntary 

conservation activities on their property 

for threatened and endangered species, 

but may not continue these efforts if 

there is a significant regulatory or 

economic burden to do so. 

The conservation benefits of critical 

habitat are primarily regulatory or 

prohibitive in nature. Where consistent 

with the discretion provided by the Act, 

we believe it is necessary to implement 

policies that provide positive incentives 

to non-Federal landowners to 

voluntarily conserve natural resources, 

and that remove or reduce disincentives 

to conservation (Wilcove et al. 1998, p. 

614; Michael 2001, pp. 34 and 36–37). 

Thus, for the recovery of Lupinus 

sulphureus ssp. Kincaidii, we believe it 

is important to build on continued 

conservation activities such as those 

with a proven partner, and to provide 

incentives for non-Federal landowners 

who might be considering implementing 

voluntary conservation activities but 

have concerns about incurring 

incidental regulatory or economic 

impacts. 

Approximately 80 percent of 

imperiled species in the United States 

occur partly or solely on private lands 

where the Service has little management 

authority (Wilcove et al. 1996 p. 2). In 

addition, recovery actions involving the 

reintroduction of listed species onto 

private lands require the voluntary 

cooperation of the landowner (Bean 

2002, p. 414; James 2002, p. 270; Knight 

1999, p. 224; Main et al. 1999, p. 1,263; 

Norton 2000, pp. 1,221–1,222; Shogren 

et al. 1999, p. 1,260; Wilcove et al. 1998, 

p. 614). Therefore, ‘‘a successful 

recovery program is highly dependent 

on developing working partnerships 

with a wide variety of entities, and the 

voluntary cooperation of thousands of 

non-Federal landowners and others is 

essential to accomplishing recovery for 

listed species’’ (Crouse et al. 2002, p. 

720). Since land suitable for 

conservation of many threatened and 

endangered species is mostly owned by 

private landowners, successful recovery 

of Lupinus sulphureus ssp. kincaidii in 

Oregon and Washington is especially 

dependent on working partnerships and 

the voluntary cooperation of private 

landowners. 

Another benefit of excluding unit KL–

1A from the critical habitat designation 

includes relieving additional regulatory 

burden and costs associated with the 

preparation of portions of section 7 

consultation documents related to 

critical habitat. While the cost of adding 

these additional sections to assessments 

and consultations is relatively minor, 

there could be delays which can 


rwilkins on PROD1PC63 with RULES_2
63900 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

generate real costs to some project 

proponents. However, because critical 

habitat in this case only includes 

proposed for occupied areas already 

subject to section 7 consultation and 

jeopardy analysis, it is anticipated this 

reduction would be minimal. 

(3) The Benefits of Exclusion Outweigh 

the Benefits of Inclusion 

Based on the above considerations, 

we have determined that the benefits of 

excluding unit KL–1A from the final 

designation of critical habitat outweigh 

the benefits of including it as critical 

habitat for Lupinus sulphureus ssp. 

kincaidii. This conclusion is based on 

the following factors: 

(a) In the past, the landowners have 

cooperated with Federal and State 

agencies and private organizations to 

implement voluntary conservation 

activities on their property that have 

resulted in tangible conservation 

benefits for Lupinus sulphureus ssp. 

kincaidii. Since purchasing the property 

in 1967, the landowners have 

maintained several healthy L. 

sulphureus ssp. kincaidii patches and 

developed a farm management plan to 

ensure that L. sulphureus ssp. kincaidii 

will continue to flourish and possibly 

expand on their property. 

(b) Simple regulation of ‘‘harmful 

activities’’ is not sufficient to conserve 

Lupinus sulphureus ssp. kincaidii. NonFederal landowner cooperation and 

support is required to prevent the 

extinction and promote the recovery of 

L. sulphureus ssp. kincaidii within its 

historic range. Future conservation 

efforts will require the cooperation of 

other non-Federal landowners. The 

exclusion of unit KL–1A will help the 

Service to maintain and improve the 

voluntary conservation partnership by 

formally recognizing the positive 

contributions of the landowners and by 

reducing unnecessary regulatory 

oversight. 

(c) Given the current management 

status of the Farm, we believe there will 

be little additional regulatory benefit to 

Lupinus sulphureus ssp. kincaidii by 

including unit KL–1A as critical habitat 

because (i) there is a low likelihood that 

the unit will be negatively affected to 

any significant degree by Federal 

activities requiring section 7 

consultation, and (ii) the unit is already 

occupied by the species and a section 7 

nexus already exists. 

In conclusion, we find that the 

exclusion of unit KL–1A from the final 

designation of critical habitat for 

Lupinus sulphureus ssp. kincaidii 

would most likely have a net positive 

conservation effect on the recovery and 

conservation of the species and the 

features essential to its conservation 

when compared to the positive 

conservation effects of a critical habitat 

designation. As described above, the 

overall benefit of designating the unit as 

critical habitat for L. sulphureus ssp. 

kincaidii is relatively small. In contrast, 

we believe that this exclusion will 

enhance our existing non-Federal lands 

partnerships, and it will set a positive 

example and provide positive incentives 

to other non-Federal landowners who 

may be considering implementing 

voluntary conservation activities on 

their properties. Therefore, the area 

included within KL–1A in the proposed 

critical habitat designation will be 

excluded from the final designation. 

(4) Exclusion of This Unit Will Not 

Cause Extinction of the Species 

In considering whether exclusion of 

unit KL–1A might result in the 

extinction of Lupinus sulphureus ssp. 

kincaidii, we first considered the 

impacts to the species. Our conclusion 

is that the conservation efforts on the 

Farm will provide as much or more net 

conservation benefits as would be 

provided if the unit was designated as 

critical habitat. These conservation 

efforts, as described above, will provide 

tangible proactive conservation benefits 

that will reduce the likelihood of 

extinction for L. sulphureus ssp. 

kincaidii in the unit, and increase the 

likelihood of its recovery in the local 

area. Extinction of L. sulphureus ssp. 

kincaidii as a consequence of this 

exclusion is unlikely; no known threats 

exist in thr area because any current or 

reasonably anticipated Federal actions 

would likely be regulated under section 

7 of the Act. Further, the unit is already 

occupied by L. sulphureus ssp. kincaidii 

and would benefit from the section 7 

protections of the Act if a Federal threat 

actually materialized. The exclusion of 

unit KL–1A from the final designation 

of critical habitat will not increase the 

risk of extinction to the species, and it 

may increase the likelihood that the 

species will recover further by 

encouraging other non-Federal 

landowners to implement voluntary 

conservation activities, as the 

landowners of the Farm have done. 

Private Timber Company Lands in 

Douglas County 

The proposed critical habitat for 

Lupinus sulphureus ssp. kincaidii in 

Douglas County, Oregon, included land 

owned by Roseburg Forest Products, 

Seneca Jones Timber Company, and 

Lone Rock Timber Management 

Company (companies) in units KL–14B, 

KL–15A, and KL–15B. The lands are 

occupied by L. sulphureus ssp. kincaidii 

and support the features essential to the 

conservation of the species. In 

conjunction with the Service, these 

companies have developed a formal 

voluntary agreement for the 

conservation of L. sulphureus ssp. 

kincaidii on their respective properties, 

including units KL–14B, KL–15A, and 

KL–15B. The companies agree to 

collaborate with us to protect and 

conserve L. sulphureus ssp. kincaidii 

populations on their private lands. 

Active management identified in the 

voluntary agreement will allow for an 

adaptive management approach within 

the units to benefit L. sulphureus ssp. 

kincaidii. The agreement accomplishes 

this through such activities as—training 

staff to identify L. sulphureus ssp. 

kincaidii and locate known population 

occurrence; conducting, or aiding in, 

monitoring within the known L. 

sulphureus ssp. kincaidii populations 

on the private lands; notifying us of new 

L. sulphureus ssp. kincaidii occurrences 

that are found; controlling noxious 

weeds and competing vegetation 

through mechanical and chemical 

control; and coordinating L. sulphureus 

ssp. kincaidii propagation activities 

with us for seed procurement and 

selection of appropriate introduction 

sites for establishing new populations 

and expanding known populations. 

Currently, habitat conditions that 

support several vigorous L. sulphureus 

ssp. kincaidii patches occur on these 

companies’ lands. 

If critical habitat designation in units 

KL–14B, KL–15A, and KL–15B reduces 

the likelihood that these voluntary 

conservation activities will be carried 

out, and at the same time fails to confer 

a counterbalancing positive regulatory 

or educational benefit to the species, 

then the benefits of excluding the units 

from critical habitat outweigh the 

benefits of including it. 

(1) Benefits of Inclusion 

Critical habitat was proposed for 

Lupinus sulphureus ssp. kincaidii in 

unit KL–14B on land owned by Lone 

Rock Timber Management Company 

and Seneca Jones Timber Company, and 

units KL–15A and KL–15B owned by 

Roseburg Forest Products. The primary 

direct benefit of inclusion of this land 

as critical habitat would result from the 

requirement under section 7 of the Act 

that Federal agencies consult with us to 

ensure that any proposed Federal action 

does not destroy or adversely modify 

critical habitat. Without critical habitat, 

some site-specific projects might not 

trigger consultation requirements under 

the Act in areas where the species is not 

currently present; in contrast, Federal 

actions in areas occupied by listed 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63901 

species would still require consultation 

under section 7 of the Act. However, 

these units are already occupied habitat 

for L. sulphureus ssp. kincaidii. 

Therefore, any Federal activities, such 

as discretionary right-of-way permits, 

that may affect these areas will in all 

likelihood require section 7 

consultation. The land is in permanent 

timber management status and is not 

expected to be developed. Therefore, we 

anticipate little additional regulatory 

benefits from including these private 

lands in critical habitat beyond what is 

already provided by the existing section 

7 nexus for habitat areas occupied by 

the listed species. 

Another possible benefit from the 

designation of critical habitat is that 

designation can serve to educate the 

public regarding the potential 

conservation value of an area. 

Information provided to a wide 

audience of the public, including other 

parties engaged in conservation 

activities, about L. sulphureus ssp. 

kincaidii and the features that are 

essential to its conservation identified 

on private timber lands in Douglas 

County could have a positive 

conservation benefit. The companies are 

currently in communication with us, 

and it is unclear that additional 

educational value would be provided as 

a result of critical habitat designation 

beyond the current level of awareness 

that exists concerning the presence of 

populations of L. sulphureus ssp. 

kincaidii that occur on the properties. 

In sum, we believe that a critical 

habitat designation for Lupinus 

sulphureus ssp. kincaidii on these 

private timber lands in Douglas County 

would provide a relatively low level of 

additional conservation benefit to the 

plant beyond what is already provided 

by existing section 7 consultation 

requirements due to the physical 

presence of this species. Based on a 

review of past consultations and 

consideration of the likely future 

activities in this specific area, there is 

little Federal activity expected to occur 

on this privately owned land that would 

trigger section 7 consultation. We also 

believes it is unlikely that critical 

habitat designation would provide 

additional educational benefits since the 

private timber companies are already 

aware of these populations and are 

participating with us in a voluntary 

agreement to conserve L. sulphureus 

ssp. kincaidii on their lands. 

(2) Benefits of Exclusion 

Proactive voluntary conservation 

efforts are necessary to prevent the 

extinction and promote the recovery of 

Lupinus sulphureus ssp. kincaidii 

within its historic range in Douglas 

County. Consideration of this concern is 

especially important in areas where the 

species has been extirpated and its 

recovery may require access and 

permission for reintroduction efforts. 

For example, L. sulphureus ssp. 

kincaidii has been extirpated from many 

of its historical locations in Oregon and 

Washington, and reestablishment is 

likely not possible without human 

assistance and non-Federal landowner 

cooperation. 

As described above, the companies 

are cooperating with Federal agencies to 

protect Lupinus sulphureus ssp. 

kincaidii patches on their properties. 

They are willing to conduct voluntary 

conservation activities on their property 

for endangered species, but may not 

continue these efforts if there is a 

significant regulatory or economic 

burden to do so. 

The conservation benefits of critical 

habitat are primarily regulatory or 

prohibitive in nature. Where consistent 

with the discretion provided by the Act, 

we believe it is necessary to implement 

policies that provide positive incentives 

to non-Federal landowners to 

voluntarily conserve natural resources, 

and that remove or reduce disincentives 

to conservation (Wilcove et al. 1998, p. 

614; Michael 2001, pp. 34 and 36–37). 

Therefore, for the recovery of Lupinus 

sulphureus ssp. Kincaidii, we believe it 

is important to build on continued 

conservation activities such as those 

with a committed partner, and to 

provide incentives for non-Federal 

landowners who might be considering 

implementing voluntary conservation 

activities but have concerns about 

incurring incidental regulatory or 

economic impacts. 

Approximately 80 percent of 

imperiled species in the United States 

occur partly or solely on private lands 

where the Service has little management 

authority (Wilcove et al. 1996 p. 2). In 

addition, recovery actions involving the 

reintroduction of listed species onto 

private lands require the voluntary 

cooperation of the landowner (Bean 

2002, p. 414; James 2002, p. 270; Knight 

1999, p. 224; Main et al. 1999, p. 1,263; 

Norton 2000, pp. 1,221–1,222; Shogren 

et al. 1999, p. 1,260; Wilcove et al. 1998, 

p. 614). Therefore, ‘‘a successful 

recovery program is highly dependent 

on developing working partnerships 

with a wide variety of entities, and the 

voluntary cooperation of thousands of 

non-Federal landowners and others is 

essential to accomplishing recovery for 

listed species’’ (Crouse et al. 2002, p. 

720). Since land suitable for 

conservation of many threatened and 

endangered species is mostly owned by 

private landowners, successful recovery 

of Lupinus sulphureus ssp. kincaidii in 

Oregon and Washington is especially 

dependent upon working partnerships 

and the voluntary cooperation of private 

landowners. 

We believe that Lupinus sulphureus 

ssp. kincaidii will benefit substantially 

from the companies’ voluntary 

management actions to protect existing 

populations, reduce nonnative weed 

competition, and expand existing 

populations through propagation efforts. 

The conservation benefits of critical 

habitat are primarily regulatory or 

prohibitive in nature; simply preventing 

‘‘harmful activities’’ will not slow the 

extinction of listed plant species (Bean 

1998). 

(3) The Benefits of Exclusion Outweigh 

the Benefits of Inclusion 

Based on the above considerations, 

we have determined that the benefits of 

excluding the lands owned by Roseburg 

Forest Products, Seneca Jones Timber 

Company, and Lone Rock Timber 

Management Company from the final 

designation of critical habitat outweigh 

the benefits of including it as critical 

habitat for Lupinus sulphureus ssp. 

kincaidii. This conclusion is based on 

the following factors: 

(a) The companies are cooperating 

with Federal agencies to implement 

voluntary conservation activities on 

their properties that are expected to 

result in tangible conservation benefits 

for Lupinus sulphureus ssp. kincaidii. A 

formal voluntary agreement has been 

signed by the companies and the 

Service. This agreement includes 

conservation actions that will maintain 

several vigorous L. sulphureus ssp. 

kincaidii patches and ensure that L. 

sulphureus ssp. kincaidii will continue 

to flourish and possibly expand on their 

properties. 

(b) Regulation of ‘‘harmful activities’’

is not sufficient to conserve this species. 

Landowner cooperation and support is 

required to prevent the extinction and 

promote the recovery of Lupinus 

sulphureus ssp. kincaidii due to the 

need to implement proactive 

conservation actions such as avoidance, 

weed control, and fire suppression. The 

voluntary agreement will promote 

conservation actions such as control of 

nonnative species and in doing so will 

require the cooperation of the three 

private timber companies. Exclusion of 

land from this critical habitat 

designation will help us maintain and 

improve this partnership by formally 

recognizing the positive contributions of 

the companies to recovery of L. 

sulphureus ssp. kincaidii, and by 


rwilkins on PROD1PC63 with RULES_2
63902 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

streamlining or reducing unnecessary 

regulatory oversight. 

Excluding this private land from 

critical habitat may, by way of example, 

provides positive incentives to other 

non-Federal landowners in Oregon 

whose lands could contribute to listed 

species recovery if voluntary 

conservation measures are implemented 

on them. 

(c) The designation of critical habitat 

can serve to educate the general public 

as well as conservation organizations 

regarding the potential conservation 

value of an area, but this goal is already 

being accomplished through ongoing 

communication between the companies, 

Roseburg BLM, and the Service. 

Likewise, there will be little additional 

Federal regulatory benefit to the species 

because (i) there is a low likelihood that 

this area will be negatively affected to 

any significant degree by Federal 

activities requiring section 7 

consultation, and (ii) this area is already 

occupied by the listed species and a 

section 7 nexus already exists. We are 

unable to identify any other potential 

benefits associated with critical habitat 

for the private lands. 

In conclusion, we find that the 

exclusion of units KL–14B, KL–15A, 

and KL–15B from the final designation 

of critical habitat for Lupinus 

sulphureus ssp. kincaidii would most 

likely have a net positive conservation 

effect on the recovery and conservation 

of the species and the features essential 

to its conservation when compared to 

the positive conservation effects of a 

critical habitat designation. As 

described above, the overall benefits to 

this species of a critical habitat 

designation for the companies’ lands is 

relatively small. In contrast, we believe 

that this exclusion will enhance our 

existing partnership with the 

companies, and it will set a positive 

example and provide positive incentives 

to other non-Federal landowners who 

may be considering implementing 

voluntary conservation activities on 

their lands. There is a higher likelihood 

of beneficial conservation activities 

occurring without designated critical 

habitat than there would be with 

designated critical habitat on these 

private lands. Therefore, we are 

excluding units KL–14B, KL–15A, and 

KL–15B from the final designation of 

critical habitat for L. sulphureus ssp. 

kincaidii. 

(4) Exclusion of These Units Will Not 

Cause Extinction of the Species 

In considering whether exclusion of 

units KL–14B, KL–15A, and KL–15B 

might result in the extinction of Lupinus 

sulphureus ssp. kincaidii, we first 

considered the impacts to the species. 

Our conclusion is that the voluntary 

conservation efforts of these companies 

will provide as much or more net 

conservation benefits as would be 

provided if the units were designated as 

critical habitat. These conservation 

efforts, as described above, will provide 

tangible proactive conservation benefits 

that will reduce the likelihood of 

extinction for L. sulphureus ssp. 

kincaidii in the units and increase the 

likelihood of its recovery in the local 

area. Extinction of L. sulphureus ssp. 

kincaidii as a consequence of this 

exclusion is unlikely because there are 

no known threats in this area due to any 

current or reasonably anticipated 

Federal actions that might be regulated 

under section 7 of the Act. Further, the 

units are already occupied by L. 

sulphureus ssp. kincaidii and would 

benefit from the section 7 protections of 

the Act, if a Federal threat actually 

materialized. The exclusion of units 

KL–14B, KL–15A, and KL–15B from the 

final designation of critical habitat will 

not increase the risk of extinction to the 

species, and it may increase the 

likelihood that the species will recover 

further by encouraging other nonFederal landowners to implement 

voluntary conservation activities, as the 

landowners of the companies have 

done. 

Roseburg District Bureau of Land 

Management and U.S. Forest Service 

Lands 

On April 19, 2006, we signed a 

conservation agreement with the 

Roseburg BLM and Forest Service for 

lands they manage in Douglas County, 

Oregon. The purpose of the agreement is 

to formally document the intent of the 

parties to implement recovery actions 

for Lupinus sulphureus ssp. kincaidii. 

Specifically, the agreement identifies 

objectives to protect, conserve, and 

restore habitat for each of the L. 

sulphureus ssp. kincaidii populations 

occurring on these Federal lands. The 

goal of this agreement is to implement 

the recovery actions necessary to meet 

the specific recovery criteria for L. 

sulphureus ssp. kincaidii in the Douglas 

County Recovery Zone, as specified in 

the Recovery Outline published by 

Service (USFWS 2006, pp. 12–18). 

The conservation agreement contains 

management direction that would serve 

to protect, conserve and contribute to 

the recovery by implementing recovery 

actions for Lupinus sulphureus ssp. 

kincaidii. The objectives and goals in 

the conservation agreement were 

developed specifically for L. sulphureus 

ssp. kincaidii. Two key standards 

provide strong assurances that L. 

sulphureus ssp. kincaidii will be 

protected and managed on the BLM and 

Forest Service lands. The standards are 

(1) all L. sulphureus ssp. kincaidii sites 

will be protected on BLM and Forest 

Service lands in Douglas County, and 

(2) recovery plan criteria as listed in the 

Recovery Outline (USFWS 2006, pp. 

12–18) for L. sulphureus ssp. kincaidii 

will be implemented (BLM et al. 2006, 

p. 2). A site-specific draft management 

plan will be developed by December 31, 

2006, and will trigger consultation with 

us under section 7 of the Act. 

In addition to the conservation plan 

that BLM and Forest Service voluntarily 

signed, several other voluntary activities 

demonstrate BLM’s and Forest Service’s 

commitment to conservation of Lupinus 

sulphureus ssp. kincaidii and other 

listed species. Over the last 5 years, 

these agencies have completed annual L. 

sulphureus ssp. kincaidii surveys that 

have led to the identification of new 

populations. Roseburg BLM has 

developed a conservation technique that 

has improved habitat. Specifically, they 

identified the use of cattle exclusion 

fencing benefits L. sulphureus ssp. 

kincaidii. The Forest Service conducted 

a 3-year study on the effects of 

herbivory, using leaf clipping as a 

surrogate, to L. sulphureus ssp. 

kincaidii, and has enhanced protection 

of the population by excluding cattle 

from the areas occupied by the plant. 

The Forest Service and BLM also 

actively manage and protect lands in an 

effort to help in the recovery of other 

federally listed species such as 

Plagiobothrys hirtus (rough 

popcornflower), northern spotted owl 

(Strix occidentalis caurina), American 

bald eagle (Haliaeetus leucocephalus) 

and marbled murrelet (Brachyramphus 

marmoratus). 

We believe that the standards and 

guidelines outlined in the conservation 

agreement and the agencies 

commitment to protect and recover 

federally listed species through section 

7(a)(1) and 7(a)(2), adequately address 

identified threats to Lupinus sulphureus 

ssp. kincaidii and its habitat. Therefore, 

the relative benefits of inclusion of these 

lands within designated critical habitat 

are diminished. 

(1) Benefits of Inclusion 

The primary effect of designating any 

particular area as critical habitat is the 

requirement for Federal agencies to 

consult with us pursuant to section 7 of 

the Act to ensure actions they carry out, 

authorize, or fund do not destroy or 

adversely modify designated critical 

habitat. Absent critical habitat 

designation, Federal agencies remain 

obligated under section 7 to consult 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63903 

with us on actions that may affect a 

federally listed species to ensure such 

actions do not jeopardize the species’

continued existence. The Forest Service 

and BLM routinely consult with us for 

activities on lands they manage that 

may affect federally listed species to 

ensure that the continued existence of 

such species is not jeopardized. 

Designation of critical habitat may 

also provide educational benefits by 

informing land managers of areas 

essential to the conservation of the 

Lupinus sulphureus ssp. kincaidii. In 

the case of Roseburg BLM and the 

Umpqua National Forest, there is no 

appreciable educational benefit because 

these land managers have already 

demonstrated their knowledge and 

understanding of habitat for the species 

through their active recovery efforts and 

consultation. The benefits of including 

these Federal lands in designated 

critical habitat are minimal, because the 

land managers are currently 

implementing conservation actions for 

L. sulphureus ssp. kincaidii and are 

committed to meeting recovey criteria 

for L. sulphureus ssp. kincaidii in 

Douglas County. This is equal to or 

exceeds benefits that would be realized 

if critical habitat were designated. 

(2) Benefits of Exclusion 

Designation of critical habitat on the 

Umpqua National Forest and Roseburg 

BLM lands would trigger a requirement 

for the Forest Service and BLM to 

consult on activities that may affect 

designated critical habitat. Designation 

of critical habitat would also require 

reinitiating consultation on ongoing 

activities where a consultation may 

have already been completed that 

assessed the effects to a federally listed 

species. If critical habitat is designated 

there will be new administrative costs 

associated with the additional 

consultations or the need to revisit 

completed consultations. The benefit of 

using those resources for specific 

conservation activities exceeds the 

benefit of completing additional 

consultations. If the area is designated 

as critical habitat, it might adversely 

impact the agencies’ ability to devote 

limited resources to the voluntary 

conservation measures noted above, 

which exceed those that could be 

realized from a critical habitat 

designation. 

(3) Benefits of Exclusion Outweigh the 

Benefits of Inclusion 

We find that the benefits of 

designating critical habitat for Lupinus 

sulphureus ssp. kincaidii on Federal 

lands in Douglas County are small in 

comparison to the benefits of excluding 

these specific areas from the final 

designation. Exclusion would enhance 

the partnership efforts with the BLM 

and Forest Service focused on 

conservation of the species on the lands 

they manage, and potentially reduce 

some of the administrative costs during 

consultation pursuant to section 7 of the 

Act. Therefore, we find the benefits of 

exclusion outweigh the benefits of 

inclusion. 

(4) The Exclusion Will Not Result in 

Extinction of the Species 

We believe that the exclusion of 

Douglas County Federal lands from 

critical habitat would not result in the 

extinction of Lupinus sulphureus ssp. 

kincaidii, because current conservation 

efforts and conservation agreement 

commitments for Douglas County 

Federal lands adequately protect 

important L. sulphureus ssp. kincaidii 

habitat and go beyond this to provide 

appropriate management to maintain 

and enhance the primary constituent 

elements in order to specifically meet 

recovery criteria for L. sulphureus ssp. 

kincaidii. Designation of critical habitat 

would not require the current 

conservation efforts, but only that 

habitat not be destroyed or adversely 

modified. There is no reason to believe 

that this exclusion would result in 

extinction of the species. 

Economic Analysis 

Section 4(b)(2)of the Act requires us 

to designate critical habitat on the basis 

of the best scientific information 

available and to consider the economic 

and other relevant impacts of 

designating a particular area as critical 

habitat. We may exclude areas from 

critical habitat upon a determination 

that the benefits of such exclusions 

outweigh the benefits of specifying such 

areas as critical habitat. We cannot 

exclude such areas from critical habitat 

when such exclusion will result in the 

extinction of the species concerned. 

Following the publication of the 

proposed critical habitat designation, 

we conducted an economic analysis to 

estimate the potential economic effect of 

the designation. The draft analysis was 

made available for public review on 

June 15, 2006 (71 FR 34566). We 

accepted comments on the draft analysis 

until June 30, 2006. 

The primary purpose of the economic 

analysis is to estimate the potential 

economic impacts associated with the 

designation of critical habitat for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens. This 

information is intended to assist the 

Secretary in making decisions about 

whether the benefits of excluding 

particular areas from the designation 

outweigh the benefits of including those 

areas in the designation. This economic 

analysis considers the economic 

efficiency effects that may result from 

the designation, including habitat 

protections that may be co-extensive 

with the listing of the species. It also 

addresses distribution of impacts, 

including an assessment of the potential 

effects on small entities and the energy 

industry. This information can be used 

by the Secretary to assess whether the 

effects of the designation might unduly 

burden a particular group or economic 

sector. 

This analysis focuses on the direct 

and indirect costs of the rule. However, 

economic impacts to land use activities 

can exist in the absence of critical 

habitat. These impacts may result from, 

for example, local zoning laws, State 

and natural resource laws, and 

enforceable management plans and best 

management practices applied by other 

State and Federal agencies. Economic 

impacts that result from these types of 

protections are not included in the 

analysis as they are considered to be 

part of the regulatory and policy 

baseline. 

The economic analysis addresses the 

effects of Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens 

conservation efforts on activities 

occurring on lands proposed for 

designation. The potential activities 

anticipated to have economic effects 

may include development, management 

of public and conservancy lands, 

transportation operations, and the 

Benton County Habitat Conservation 

Plan (HCP). Development-related losses 

account for 35 percent of forecasted 

costs; another 30 percent of the 

forecasted costs are associated with 

managing public and conservancy lands 

costs; another 30 percent of forecasted 

costs are associated with transportation 

operations, and 5 percent are associated 

with the Benton County Habitat 

Conservation Planning (HCP) costs. 

In the economic impact analysis, 

development impacts are presented 

based on the assumption that due to the 

small, tightly defined boundaries of the 

critical habitat designation, where 

development falls within critical habitat 

boundaries and there is a Federal nexus, 

it would be difficult for development to 

proceed without adversely modifying 

critical habitat. Post-designation costs 

are expected to range from $25.3 to 

$52.7 million in undiscounted 2006 

dollars. In present value terms, this 

range is equivalent to $19.1 to $40.3 

million (assuming a 3 percent discount 


rwilkins on PROD1PC63 with RULES_2
63904 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

rate) and $15.3 to $32.6 million 

(assuming a 7 percent discount rate). 

The total economic impacts are not 

uniformly distributed across the habitat 

subunits. In fact, there is a large 

variation in economic impacts between 

subunits that contain privately owned 

developable land. Land use restrictions 

are expected to have the greatest 

economic impact in subunit Fender’s 

blue butterfly (FBB)–8 (Wren), which 

includes overlap with Lupinus 

sulphureus ssp. kincaidi (KL)–9 (also 

named Wren). This unit includes the 

largest area of privately owned land 

(713 acres). Subunit FBB–4B (Baskett 

Butte) contains the next largest area of 

private land within the critical habitat 

designation (327 acres). Together, these 

subunits contain almost 50 percent of 

the private land within the critical 

habitat designation, and account for 

approximately 45 percent of the 

development-related economic impacts, 

which represents 10 percent of the total 

costs/impacts. 

Pursuant to section 4(b)(2) of the Act, 

we must consider relevant impacts in 

addition to economic ones. We 

determined that the lands within the 

designation of critical habitat for 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens are not 

owned or managed by the Department of 

Defense; there are currently no habitat 

conservation plans for Fender’s blue 

butterfly, L. sulphureus ssp. kincaidii, or 

E. decumbens var. decumbens; and the 

designation does not include any Tribal 

lands or trust resources. We anticipate 

no impact to national security, Tribal 

lands, partnerships, or habitat 

conservation plans from this critical 

habitat designation. Based on the best 

available information, including the 

prepared economic analysis, we believe 

that all of these units contain the 

features essential for the conservation of 

this species. Our economic analysis 

indicates an overall low cost resulting 

from the designation. Therefore, we 

have found no areas for which the 

benefits of exclusion outweigh the 

benefits of inclusion for Fender’s blue 

butterfly, L. sulphureus ssp. kincaidii, or 

E. decumbens var. decumbens based on 

economic impacts. 

A copy of the final economic analysis 

with supporting documents is included 

in our administrative record and may be 

obtained by contacting U.S. Fish and 

Wildlife Service, Branch of Endangered 

Species (see ADDRESSES section) or by

Required Determinations 

Regulatory Planning and Review 

In accordance with Executive Order 

12866, this document is a significant 

rule in that it may raise novel legal and 

policy issues. On the basis of the final 

economic analysis, we have determined 

that the post designation costs may 

range from $25.3 to $52.7 million in 

undiscounted 2006 dollars. In present 

value terms, this range is equivalent to 

$19.1 to $40.3 million (assuming a 3 

percent discount rate) and $15.3 to 

$32.6 million (assuming a 7 percent 

discount rate). As such, this designation 

will not have an annual effect on the 

economy of $100 million or more or 

affect the economy in a material way. 

Due to the tight timeline for publication 

in the Federal Register, the Office of 

Management and Budget (OMB) has not 

formally reviewed this rule. 

Further, Executive Order 12866 

directs Federal Agencies promulgating 

regulations to evaluate regulatory 

alternatives (Office of Management and 

Budget, Circular A–4, September 17, 

2003). Pursuant to Circular A–4, once it 

has been determined that the Federal 

regulatory action is appropriate, the 

agency will need to consider alternative 

regulatory approaches. Since the 

determination of critical habitat is a 

statutory requirement under the Act, we 

must then evaluate alternative 

regulatory approaches, where feasible, 

when promulgating a designation of 

critical habitat. 

In developing our designations of 

critical habitat, we consider economic 

impacts, impacts to national security, 

and other relevant impacts under 

section 4(b)(2) of the Act. Based on the 

discretion allowable under this 

provision, we may exclude any 

particular area from the designation of 

critical habitat providing that the 

benefits of such exclusion outweigh the 

benefits of specifying the area as critical 

habitat, and that such exclusion would 

not result in the extinction of the 

species. As such, we believe that the 

evaluation of the inclusion or exclusion 

of particular areas, or combined thereof, 

in a designation constitutes our 

regulatory alternative analysis. 

As explained above, we prepared an 

economic analysis of this action. We 

used this analysis to meet the 

requirement of section 4(b)(2) of the Act 

to determine the economic 

consequences of designating the specific 

areas as critical habitat. We also used it 

to help determine whether to exclude 

any area from critical habitat, as 

provided for under section 4(b)(2). 

Regulatory Flexibility Act (5 U.S.C. 601 

et seq.) 

Under the Regulatory Flexibility Act 

(RFA) (as amended by the Small 

Business Regulatory Enforcement 

Fairness Act (SBREFA) of 1996), 

whenever an agency is required to 

publish a notice of rulemaking for any 

proposed or final rule, it must prepare 

and make available for public comment 

a regulatory flexibility analysis that 

describes the effect of the rule on small 

entities (i.e., small businesses, small 

organizations, and small government 

jurisdictions). However, no regulatory 

flexibility analysis is required if the 

head of an agency certifies the rule will 

not have a significant economic impact 

on a substantial number of small 

entities. The SBREFA amended the RFA 

to require Federal agencies to provide a 

statement of factual basis for certifying 

that the rule will not have a significant 

economic impact on a substantial 

number of small entities. The SBREFA 

also amended the RFA to require a 

certification statement. 

Small entities include small 

organizations, such as independent 

nonprofit organizations; small 

governmental jurisdictions, including 

school boards and city and town 

governments that serve fewer than 

50,000 residents; as well as small 

businesses. Small businesses include 

manufacturing and mining concerns 

with fewer than 500 employees, 

wholesale trade entities with fewer than 

100 employees, retail and service 

businesses with less than $5 million in 

annual sales, general and heavy 

construction businesses with less than 

$27.5 million in annual business, 

special trade contractors doing less than 

$11.5 million in annual business, and 

agricultural businesses with annual 

sales less than $750,000. To determine 

if potential economic impacts to these 

small entities are significant, we 

consider the types of activities that 

might trigger regulatory impacts under 

this rule, as well as the types of project 

modifications that may result. In 

general, the term ‘‘significant economic 

impact’’ is meant to apply to a typical 

small business firm’s business 

operations. 

To determine if the rule could 

significantly affect a substantial number 

of small entities, we consider the 

number of small entities affected within 

particular types of economic activities 

(e.g., housing development, grazing, oil 

and gas production, timber harvesting). 

We apply the ‘‘substantial number’’ test 

individually to each industry to 

determine if certification is appropriate. 

However, the SBREFA does not 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63905 

explicitly define ‘‘substantial number’’

or ‘‘significant economic impact.’’

Consequently, to assess whether a 

‘‘substantial number’’ of small entities is 

affected by this designation, this 

analysis considers the relative number 

of small entities likely to be impacted in 

an area. In some circumstances, 

especially with critical habitat 

designations of limited extent, we may 

aggregate across all industries and 

consider whether the total number of 

small entities affected is substantial. In 

estimating the number of small entities 

potentially affected, we also consider 

whether their activities have any 

Federal involvement. 

Designation of critical habitat only 

affects activities conducted, funded, or 

permitted by Federal agencies. Some 

kinds of activities are unlikely to have 

any Federal involvement and so will not 

be affected by critical habitat 

designation. Federal agencies already 

are required to consult with us under 

section 7 of the Act on activities they 

fund, permit, or implement that may 

affect Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens. Federal 

agencies also must consult with us if 

their activities may affect critical 

habitat. Designation of critical habitat, 

therefore, could result in an additional 

economic impact on small entities due 

to the requirement to reinitiate 

consultation for ongoing Federal 

activities. 

In our draft economic analysis of this 

designation, we evaluated the potential 

economic effects on small business 

entities resulting from the protection of 

the prairie species and their habitat 

related to the species and proposed 

designation of critical habitat. The 

potential activities anticipated to have 

economic effects may include 

development, management of public 

and conservancy lands, transportation 

operations, and the Benton County 

Habitat Conservation Plan (HCP). 

Development-related losses account for 

35 percent of forecasted costs; another 

30 percent of the forecasted costs are 

associated with managing public and 

conservancy lands costs; another 30 

percent of forecasted costs are 

associated with transportation 

operations, and 5 percent are associated 

with the Benton County Habitat 

Conservation Planning (HCP) costs. 

Small entities identified in the 

economic analysis included forestry, 

agriculture, and five cities. The 

potential impacts to the identified small 

entities are small. One family-owned 

forestry business was identified within 

the critical habitat designation and 

represents only one of 494 businesses 

within the eight-county critical habitat 

boundary that may be affected. It is 

estimated in the draft economic analysis 

that conservation activities may cost the 

company about $1,000 to $3,000 

annually. The draft economic analysis 

also analyzed all agricultural operations 

and concluded that the impacts by 

conservation efforts are considered 

small (the potential farms to be 

impacted represent about 1.2 percent of 

the total small farms in the eight-county 

critical habitat boundary). Of the five 

small governments identified in the 

draft economic analysis, only Dallas was 

identified as an entity potentially 

impacted by conservation activities. The 

costs were estimated to be 

approximately 0.08 to 0.5 percent of the 

City’s annual expenditures. 

In general, two different mechanisms 

in section 7 consultations could lead to 

additional regulatory requirements for 

the approximately four small 

businesses, on average, that may be 

required to consult with us each year 

regarding their project’s impact on 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens and their 

habitat. First, if we conclude, in a 

biological opinion, that a proposed 

action is likely to jeopardize the 

continued existence of a species or 

adversely modify its critical habitat, we 

can offer ‘‘reasonable and prudent 

alternatives.’’ Reasonable and prudent 

alternatives are alternative actions that 

can be implemented in a manner 

consistent with the scope of the Federal 

agency’s legal authority and 

jurisdiction, that are economically and 

technologically feasible, and that would 

avoid jeopardizing the continued 

existence of listed species or result in 

adverse modification of critical habitat. 

A Federal agency and an applicant may 

elect to implement a reasonable and 

prudent alternative associated with a 

biological opinion that has found 

jeopardy or adverse modification of 

critical habitat. An agency or applicant 

could alternatively choose to seek an 

exemption from the requirements of the 

Act or proceed without implementing 

the reasonable and prudent alternative. 

However, unless an exemption were 

obtained, the Federal agency or 

applicant would be at risk of violating 

section 7(a)(2) of the Act if it chose to 

proceed without implementing the 

reasonable and prudent alternatives. 

Second, if we find that a proposed 

action is not likely to jeopardize the 

continued existence of a listed animal or 

plant species, we may identify 

reasonable and prudent measures 

designed to minimize the amount or 

extent of take and require the Federal 

agency or applicant to implement such 

measures through nondiscretionary 

terms and conditions. We may also 

identify discretionary conservation 

recommendations designed to minimize 

or avoid the adverse effects of a 

proposed action on listed species or 

critical habitat, help implement 

recovery plans, or to develop 

information that could contribute to the 

recovery of the species. 

Based on our experience with 

consultations pursuant to section 7 of 

the Act for all listed species, virtually 

all projects—including those that, in 

their initial proposed form, would result 

in jeopardy or adverse modification 

determinations in section 7 

consultations—can be implemented 

successfully with, at most, the adoption 

of reasonable and prudent alternatives. 

These measures, by definition, must be 

economically feasible and within the 

scope of authority of the Federal agency 

involved in the consultation. We can 

only describe the general kinds of 

actions that may be identified in future 

reasonable and prudent alternatives. 

These are based on our understanding of 

the needs of the species and the threats 

it faces, as described in the final listing 

rule and this critical habitat designation. 

Within the final critical habitat units, 

the types of Federal actions or 

authorized activities that we have 

identified as potential concerns are: 

(1) Actions that would further degrade 

or destroy prairie habitat supporting 

populations of Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens. 

Such activities could include, but are 

not limited to, the removal or 

destruction of prairie habitat by grading, 

leveling, plowing, mowing, burning, 

operation of motorized equipment, 

herbicide spraying, or intensive grazing. 

These activities could eliminate or 

reduce the habitat necessary for 

Fender’s blue butterfly by removing the 

host plant essential for reproduction 

and larval feeding, as well as adult 

nectaring plants. Additionally, removal 

or destruction of habitat further isolates 

populations and increases the risk of 

inbreeding depression. Implementation 

of these activities in prairie habitat 

supporting L. sulphureus ssp. kincaidii 

or E. decumbens var. decumbens could 

directly eliminate individuals and the 

potential for essential population 

growth and expansion in the available 

‘‘open spaces’’ of native short-grass 

prairie habitat. 

(2) Actions that further isolate or 

reduce genetic interchange among 

populations of Fender’s blue butterfly, 

Lupinus sulphureus ssp. kincaidii, or 

Erigeron decumbens var. decumbens 


rwilkins on PROD1PC63 with RULES_2
63906 Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 

from extant locations within a unit or 

between subunits. Such activities could 

include, but are not limited to, the 

construction or expansion of roads, 

houses, buildings, or infrastructure that 

limit dispersal of the Fender’s blue 

butterfly between lupine patches, and 

limit the dispersal of plant pollinators 

between L. sulphureus ssp. kincaidii 

and E. decumbens var. decumbens 

populations. These activities reduce the 

opportunity for population growth and 

decrease genetic diversity by limiting 

normal breeding behaviors. 

The most likely Federal nexus by 

which these activities would be 

consulted upon include: Regulation of 

activities affecting waters of the United 

States by the Corps under section 404 of 

the Clean Water Act; road construction 

and maintenance, and right-of-way 

designation funded by the Federal 

Highway Administration; Federal 

regulation of agricultural activities; 

hazard mitigation and post-disaster 

repairs funded by the Federal 

Emergency Management Agency; and 

activities funded by the Environmental 

Protection Agency, U.S. Department of 

Agriculture, or any other Federal 

agency. 

It is likely that a developer or other 

project proponent could modify a 

project or take measures to protect 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens. The kinds 

of actions that may be included if future 

reasonable and prudent alternatives 

become necessary include conservation 

set-asides, management of competing 

nonnative species, restoration of 

degraded habitat, and regular 

monitoring. These are based on our 

understanding of the needs of the 

species and the threats it faces, as 

described in the final listing rule and 

proposed critical habitat designation. 

These measures are not likely to result 

in a significant economic impact to 

project proponents. 

In summary, we have considered 

whether this critical habitat designation 

would result in a significant economic 

effect on a substantial number of small 

entities. We have determined, for the 

above reasons and based on currently 

available information, that it is not 

likely to affect a substantial number of 

small entities. Federal involvement, and 

thus section 7 consultations, would be 

limited to a subset of the area 

designated. The most likely Federal 

involvement could include Corps 

permits, permits we may issue under 

section 10(a)(1)(B) of the Act, Federal 

Highways Administration funding for 

road improvements, and Federal 

funding for conservation activities. A 

regulatory flexibility analysis is not 

required. 

Small Business Regulatory Enforcement 

Fairness Act (5 U.S.C 801 et seq.) 

Under SBREFA, this rule is not a 

major rule. Our detailed assessment of 

the economic effects of this designation 

is described in the economic analysis. 

Based on the effects identified in the 

economic analysis, we have determined 

that this rule will not have an annual 

effect on the economy of $100 million 

or more, will not cause a major increase 

in costs or prices for consumers, and 

will not have significant adverse effects 

on competition, employment, 

investment, productivity, innovation, or 

the ability of U.S.-based enterprises to 

compete with foreign-based enterprises. 

Refer to the final economic analysis for 

a discussion of the effects of this 

determination. 

Executive Order 13211 

On May 18, 2001, the President issued 

Executive Order 13211 on regulations 

that significantly affect energy supply, 

distribution, and use. Executive Order 

13211 requires agencies to prepare 

Statements of Energy Effects when 

undertaking certain actions. This final 

rule to designate critical habitat for the 

Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, and Erigeron 

decumbens var. decumbens is not 

expected to significantly affect energy 

supplies, distribution, or use. Therefore, 

this action is not a significant energy 

action and no Statement of Energy 

Effects is required. 

Unfunded Mandates Reform Act (2 

U.S.C. 1501 et seq.) 

In accordance with the Unfunded 

Mandates Reform Act (2 U.S.C. 1501 et 

seq.), we make the following findings: 

(a) This rule will not produce a 

Federal mandate. In general, a Federal 

mandate is a provision in legislation, 

statute, or regulation that would impose 

an enforceable duty upon State, local, 

Tribal governments, or the private sector 

and includes both ‘‘Federal 

intergovernmental mandates’’ and 

‘‘Federal private sector mandates.’’

These terms are defined in 2 U.S.C. 

658(5)–(7). ‘‘Federal intergovernmental 

mandate’’ includes a regulation that 

‘‘would impose an enforceable duty 

upon State, local, or tribal governments’’

with two exceptions. It excludes ‘‘a 

condition of federal assistance.’’ It also 

excludes ‘‘a duty arising from 

participation in a voluntary Federal 

program,’’ unless the regulation ‘‘relates 

to a then-existing Federal program 

under which $500,000,000 or more is 

provided annually to State, local, and 

tribal governments under entitlement 

authority,’’ if the provision would 

‘‘increase the stringency of conditions of 

assistance’’ or ‘‘place caps upon, or 

otherwise decrease, the Federal 

Government’s responsibility to provide 

funding’’ and the State, local, or Tribal 

governments ‘‘lack authority’’ to adjust 

accordingly. (At the time of enactment, 

these entitlement programs were: 

Medicaid; AFDC work programs; Child 

Nutrition; Food Stamps; Social Services 

Block Grants; Vocational Rehabilitation 

State Grants; Foster Care, Adoption 

Assistance, and Independent Living; 

Family Support Welfare Services; and 

Child Support Enforcement.) ‘‘Federal 

private sector mandate’’ includes a 

regulation that ‘‘would impose an 

enforceable duty upon the private 

sector, except (i) a condition of Federal 

assistance; or (ii) a duty arising from 

participation in a voluntary Federal 

program.’’

The designation of critical habitat 

does not impose a legally binding duty 

on non-Federal government entities or 

private parties. Under the Act, the only 

regulatory effect is that Federal agencies 

must ensure that their actions do not 

destroy or adversely modify critical 

habitat under section 7. While nonFederal entities who receive Federal 

funding, assistance, permits or 

otherwise require approval or 

authorization from a Federal agency for 

an action may be indirectly impacted by 

the designation of critical habitat, the 

legally binding duty to avoid 

destruction or adverse modification of 

critical habitat rests squarely on the 

Federal agency. Furthermore, to the 

extent that non-Federal entities are 

indirectly impacted because they 

receive Federal assistance or participate 

in a voluntary Federal aid program, the 

Unfunded Mandates Reform Act would 

not apply; nor would critical habitat 

shift the costs of the large entitlement 

programs listed above on to State 

governments. 

(b) We do not believe that this rule 

will significantly or uniquely affect 

small governments because it will not 

produce a Federal mandate of $100 

million or greater in any year, that is, it 

is not a ‘‘significant regulatory action’’

under the Unfunded Mandates Reform 

Act. The designation of critical habitat 

imposes no obligations on State or local 

governments. As such, Small 

Government Agency Plan is not 

required. 

Federalism 

In accordance with Executive Order 

13132, the rule does not have significant 

Federalism effects. A Federalism 

assessment is not required. In keeping 


rwilkins on PROD1PC63 with RULES_2
Federal Register / Vol. 71, No. 210 / Tuesday, October 31, 2006 / Rules and Regulations 63907 

with DOI and Department of Commerce 

policy, we requested information from, 

and coordinated development of this 

final critical habitat designation with, 

appropriate State resource agencies in 

Oregon and Washington. The 

designation of critical habitat in areas 

currently occupied by the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, or Erigeron decumbens var. 

decumbens may impose nominal 

additional regulatory restrictions to 

those currently in place and, therefore, 

may have little incremental impact on 

State and local governments and their 

activities. The designation may have 

some benefit to these governments in 

that the areas that contain the features 

essential to the conservation of the 

species are more clearly defined, and 

the primary constituent elements of the 

habitat necessary to the conservation of 

the species are specifically identified. 

While making this definition and 

identification does not alter where and 

what federally sponsored activities may 

occur, it may assist these local 

governments in long-range planning 

(rather than waiting for case-by-case 

section 7 consultations to occur). 

Civil Justice Reform 

In accordance with Executive Order 

12988, the Office of the Solicitor has 

determined that the rule does not 

unduly burden the judicial system and 

meets the requirements of sections 3(a) 

and 3(b)(2) of the Order. We are 

designating critical habitat in 

accordance with the provisions of the 

Endangered Species Act. This final rule 

uses standard property descriptions and 

identifies the primary constituent 

elements within the designated areas to 

assist the public in understanding the 

habitat needs of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, and Erigeron decumbens var. 

decumbens. 

Paperwork Reduction Act of 1995 (44 

U.S.C. 3501 et seq.) 

This rule does not contain any new 

collections of information that require 

approval by OMB under the Paperwork 

Reduction Act. This rule will not 

impose recordkeeping or reporting 

requirements on State or local 

governments, individuals, businesses, or 

organizations. An agency may not 

conduct or sponsor, and a person is not 

required to respond to, a collection of 

information unless it displays a 

currently valid OMB control number. 

National Environmental Policy Act 

It is our position that, outside the 

Tenth Circuit, we do not need to 

prepare environmental analyses as 

defined by the NEPA in connection with 

designating critical habitat under the 

Endangered Species Act of 1973, as 

amended. We published a notice 

outlining our reasons for this 

determination in the Federal Register 

on October 25, 1983 (48 FR 49244). This 

assertion was upheld in the courts of the 

Ninth Circuit (Douglas County v. 

Babbitt, 48 F.3d 1495 (9th Cir. 1995), 

cert. denied 116 S. Ct. 698 (1996). 

Government-to-Government 

Relationship With Tribes 

In accordance with the President’s 

memorandum of April 29, 1994, 

‘‘Government-to-Government Relations 

with Native American Tribal 

Governments’’ (59 FR 22951), Executive 

Order 13175, and the Department of 

Interior’s manual at 512 DM 2, we 

readily acknowledge our responsibility 

to communicate meaningfully with 

recognized Federal Tribes on a 

government-to-government basis. We 

have determined that there are no Tribal 

lands occupied at the time of listing, 

and no tribal lands that are unoccupied 

that contain the features essential for the 

conservation of the Fender’s blue 

butterfly, Lupinus sulphureus ssp. 

kincaidii, or Erigeron decumbens var. 

decumbens. Therefore, critical habitat 

for the Fender’s blue butterfly, Lupinus 

sulphureus ssp. kincaidii, or Erigeron 

decumbens var. decumbens has not 

been designated on Tribal lands.

Fender’s blue butterfly (Icaricia 

icarioides fenderi) 

(1) Critical habitat units are depicted 

for Benton, Lane, Polk, and Yamhill 

Counties, Oregon, on the maps below. 

(2) The primary constituent elements 

of critical habitat for Fender’s blue 

butterfly are the habitat components 

that provide: 

(i) Early seral upland prairie, wet 

prairie, or oak savanna habitat with a 

mosaic of low-growing grasses and 

forbs, an absence of dense canopy 

vegetation, and undisturbed subsoils; 

(ii) Larval host-plants Lupinus 

sulphureus ssp. kincaidii, L. arbustus, or 

L. albicaulis; 

(iii) Adult nectar sources, such 

as:Allium acuminatum (tapertip onion), 

Allium amplectens (narrowleaf onion), 

Calochortus tolmiei (Tolmie’s mariposa 

lilly), Camassia quamash (small camas), 

Cryptantha intermedia (clearwater 

cryptantha), Eriophyllum lanatum 

(wooly sunflower), Geranium oreganum 

(Oregon geranium), Iris tenax (toughleaf 

iris), Linum angustifolium (pale flax), 

Linum perenne (blue flax), Sidalcea 

campestris (Meadow checkermallow), 

Sidalcea virgata (rose checker-mallow), 

Vicia cracca (bird vetch), V. sativa 

(common vetch), and V. hirsute (tiny 

vetch); 

(iv) Stepping-stone habitat consisting 

of undeveloped open areas with the 

physical characteristics appropriate for 

supporting the short-stature prairie oak 

savanna plant community (well-drained 

soils), within ∼1.2 miles (∼2 km) of natal 

lupine patches. 

(3) Critical habitat does not include 

man-made structures (such as buildings, 

aqueducts, airports, roads, and other 

paved areas, and the land on which 

such structures are located) existing on 

the effective date of this rule and not 

containing one or more of the primary 

constituent elements. 

(4) Critical Habitat Map Units. Data 

layers defining map units were created 

using USGS 24,000 scale Digital Ortho 

Quads captured in 2000. Critical habitat 

units were then mapped using Universal 

Transverse Mercator (UTM) zone 10, 

North American Datum (NAD) 1983 

coordinates.

Erigeron decumbens var. decumbens 

(Willamette daisy) and Lupinus 

sulphureus ssp. kincaidii (Kincaid’s 

lupine) in alphabetical order by family 

under Asteraceae and Fabaceae, 

respectively, to read as follows: 

§ 17.96 Critical habitat—plants. 

(a) Flowering plants. 

* * * * * 

Family Asteraceae: Erigeron 

decumbens var. decumbens (Willamette 

daisy). 

(1) Critical habitat units are depicted 

for Benton, Lane, Linn, Marion, and 

Polk Counties, Oregon, on the maps 

below. 

(2) The primary constituent elements 

of critical habitat for Erigeron 

decumbens var. decumbens are the 

habitat components that provide: 

(i) Early seral upland prairie, wet 

prairie, or oak savanna habitat with a 

mosaic of low-growing grasses and 

forbs, and spaces to establish seedlings 

or new vegetative growth; an absence of 

dense canopy vegetation; and 

undisturbed subsoils. 

(3) Critical habitat does not include 

man-made structures (such as buildings, 

aqueducts, airports, roads, and other 

paved areas, and the land on which 

such structures are located) existing on 

the effective date of this rule and not 

containing one or more of the primary 

constituent elements. 

(4) Critical habitat map units. Critical 

habitat units are described below. Data 

layers defining map units were created 

using USGS 24,000 scale Digital Ortho 

Quads captured in 2000. Critical habitat 

units were then mapped using UTM 

zone 10, NAD 1983 coordinates.

Family Fabaceae: Lupinus sulphureus 

ssp. kincaidii (Kincaid’s lupine). 

(1) Critical habitat units are depicted 

for Benton, Lane, Polk, and Yamhill 

Counties, Oregon, and Lewis County, 

Washington, on the maps below. 

(2) The primary constituent elements 

of critical habitat for the Lupinus 

sulphureus ssp. kincaidii are the habitat 

components that provide: 

(i) Early seral upland prairie, or oak 

savanna habitat with a mosaic of lowgrowing grasses and forbs, and spaces to 

establish seedlings or new vegetative 

growth; an absence of dense canopy 

vegetation; and undisturbed subsoils. 

(ii) The presence of insect outcrossing 

pollinators, such as Bombus mixtus and 

B. californicus, with unrestricted 

movement between existing lupine 

patches. 

(3) Critical habitat does not include 

man-made structures (such as buildings, 

aqueducts, airports, roads, and other 

paved areas, and the land on which 

such structures are located) existing on 

the effective date of this rule and not 

containing one or more of the primary 

constituent elements. 

(4) Critical Habitat Map Units. Critical 

habitat units are described below. Data 

layers defining map units were created 

using USGS 24,000 scale Digital Ortho 

Quads captured in 2000. Critical habitat 

units were then mapped using UTM 

zone 10, NAD 1983 coordinates.
