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 court-ordered designations have left 
the Service with limited ability to provide for public participation or 
to ensure a

[[Page 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),

[[Page 63864]]

Festuca roemeri (Roemer's fescue), Fragaria vesca (woodland 
strawberry), Hieracium albiflorum (white hawkweed), Holodiscus discolor 
(oceanspray), Lathyrus polyphyllus (leafy pea), Lonicera hispidula 
(pink honeysuckle), Pinus ponderosa (ponderosa pine), Pseudotsuga 
menziesii (Douglas fir, Doug fir), Quercus kelloggii (California black 
oak), Rubus ursinus (California blackberry), Sanicula crassicaulis 
(Pacific blacksnakeroot), Symphoricarpos albus (snowberry), Torilis 
arvensis (spreading hedgeparsley), Toxicodendron diversilobum (poison 
oak), Vicia americana (American vetch), and Whipplea modesta (common 
whipplea) (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 co-occurring with the plant including, but not limited to: 
Anthoxanthum odoratum (sweet vernalgrass), Aster curtus (white-top 
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 low-growing (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

[[Page 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

[[Page 63866]]

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 
human-induced 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 sub-watersheds.
    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 re-establishing 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 sub-watershed.
    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 cross-pollination 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 non-native 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.

[[Page 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

[[Page 63868]]

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.

[[Page 63869]]

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

[[Page 63870]]

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

[[Page 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 decision-making 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,

[[Page 63872]]

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 off-setting 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 stepping-stone 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 low-growing 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 low-growing 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.
    In this final rule, the first primary consitutent element is as

    (1) Early seral upland 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.
    In the proposed rule, the primary consitutent element for E. 
decumbens var. decumbens was as follows:
    (1) Early seral upland prairie, oak savanna habitat with a mosaic 
of low-

growing 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.
    In this final rule, the primary consitutent element is as follows:
    (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.
    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,

[[Page 63874]]

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 stepping-stone 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 low-growing 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).

[[Page 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 long-term 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

[[Page 63876]]

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 non-native 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.

[[Page 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 sexually-reproducing 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, fine-
textured, 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

[[Page 63878]]

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 low-growing 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

[[Page 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 long-term 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

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 non-
native 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 non-
native 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,

[[Page 63881]]

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.

[[Page 63884]]

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

[[Page 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 visually-obstructed 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 stepping-
stone 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 long-term 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

[[Page 63886]]

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 stepping-stone 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 stepping-stone 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

[[Page 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

[[Page 63888]]

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 northern-
most 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 <greek-i>1), this population of L. sulphureus 
ssp. kincaidii substantially contributes to the metapopulation in this 
portion of the

[[Page 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 long-term 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 long-term 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

[[Page 63890]]

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 long-term 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.

[[Page 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 short-grass 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 long-term 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 stepping-
stone 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.

[[Page 63892]]

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

[[Page 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, most-connected, 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 long-term 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 long-term 
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

[[Page 63894]]

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

[[Page 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

[[Page 63896]]

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 Non-Federal 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 well-
intentioned 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;

[[Page 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 non-Federal 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 non-Federal 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

[[Page 63898]]

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

[[Page 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 site-specific 
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

[[Page 63900]]

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. Non-Federal 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

[[Page 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

[[Page 63902]]

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 non-Federal 
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

[[Page 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

[[Page 63904]]

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 down from the Internet at http://www.fws.gov/oregonfwo/Species/ESA-Actions/WillValleyPage.asp.

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

[[Page 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

[[Page 63906]]

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 non-Federal 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

[[Page 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.

Sec.  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 low-growing 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.
