Endangered and Threatened Wildlife and Plants; Designation of 
Critical Habitat for the Miami Tiger Beetle (Cicindelidia Floridana)

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), propose to 
designate critical habitat for the Miami tiger beetle (Cicindelidia 
floridana) under the Endangered Species Act (Act). In total, 
approximately 1,977 acres (ac) (800 hectares (ha)) in Miami-Dade 
County, Florida, fall within the boundaries of the proposed critical 
habitat designation. If we finalize this rule as proposed, it would 
extend the Act's protections to this species' critical habitat. We also 
announce the availability of a draft economic analysis of the proposed 
designation of critical habitat for the Miami tiger beetle.

DATES: We will accept comments received or postmarked on or before 
November 8, 2021. Comments submitted electronically using the Federal 
eRulemaking Portal (see ADDRESSES, below) must be received by 11:59 
p.m. Eastern Time on the closing date. We must receive requests for a

SUPPLEMENTARY INFORMATION:

Executive Summary

    Why we need to publish a rule. Under the Endangered Species Act, 
any species that is determined to be a threatened or endangered species 
requires critical habitat to be designated, to the maximum extent 
prudent and determinable. Designations and revisions of critical 
habitat can only be completed by issuing a rule.
    What this document does. We propose the designation of critical 
habitat for the Miami tiger beetle, which is listed as endangered.
    The basis for our action. Section 3(5)(A) of the Act defines 
critical habitat as (i) the specific areas within the geographical area 
occupied by the species, at the time it is listed, on which are found 
those physical or biological features (I) essential to the conservation 
of the species and (II) which may require special management 
considerations or protections; and (ii) specific areas outside the 
geographical area occupied by the species at the time it is listed, 
upon a determination by the Secretary that such areas are essential for 
the conservation of the species.

[[Page 49946]]

Section 4(b)(2) of the Act states that the Secretary must make the 
designation on the basis of the best scientific data available and 
after taking into consideration the economic impact, the impact on 
national security, and any other relevant impacts of specifying any 
particular area as critical habitat.
    Draft economic analysis of the proposed designation of critical 
habitat. In order to consider the economic impacts of critical habitat 
for the Miami tiger beetle, we compiled information pertaining to the 
potential incremental economic impacts for this proposed critical 
habitat designation. The information we used in determining the 
economic impacts of the proposed critical habitat is summarized in this 
proposed rule (see Consideration of Economic Impacts) and is available 
at http://www.regulations.gov at Docket No. FWS-R4-ES-2021-0053 and at 
the Florida Ecological Services Field Office at http://ww.fws.gov/verobeach/ (see FOR FURTHER INFORMATION CONTACT). We are soliciting 
public comments on the economic information provided and any other 
potential economic impact of the proposed designation. We will continue 
to reevaluate the potential economic impacts between this proposal and 
our final designation.
    Public comment. We are seeking comments and soliciting information 
from the public on our proposed designation to make sure we consider 
the best scientific and commercial information available in developing 
our final designation. Because we will consider all comments and 
information we receive during the comment period, our final 
determination may differ from this proposal. We will respond to and 
address comments received in our final rule.
    We will seek peer review. We are seeking comments from independent 
specialists to ensure that our proposal is based on scientifically 
sound data and analyses. We have invited these peer reviewers to 
comment on our specific assumptions and conclusions in this critical 
habitat proposal.

Information Requested

    We intend that any final action resulting from this proposed rule 
will be based on the best scientific and commercial data available and 
be as accurate and as effective as possible. Therefore, we request 
comments or information from other governmental agencies, Native 
American Tribes, the scientific community, industry, or any other 
interested parties concerning this proposed rule. We particularly seek 
comments concerning:
    (1) The reasons why we should or should not designate habitat as 
``critical habitat'' under section 4 of the Act (16 U.S.C. 1531 et 
seq.), including information to inform the following factors that the 
regulations identify as reasons why designation of critical habitat may 
be not prudent:
    (a) The species is threatened by taking or other human activity and 
identification of critical habitat can be expected to increase the 
degree of such threat to the species;
    (b) The present or threatened destruction, modification, or 
curtailment of a species' habitat or range is not a threat to the 
species, or threats to the species' habitat stem solely from causes 
that cannot be addressed through management actions resulting from 
consultations under section 7(a)(2) of the Act;
    (c) Areas within the jurisdiction of the United States provide no 
more than negligible conservation value, if any, for a species 
occurring primarily outside the jurisdiction of the United States; or
    (d) No areas meet the definition of critical habitat.
    (2) Specific information on:
    (a) The amount and distribution of Miami tiger beetle habitat;
    (b) What areas, that were occupied at the time of listing and that 
contain the physical or biological features essential to the 
conservation of the species, should be included in the designation and 
why;
    (c) Any additional areas occurring within the range of the species, 
in Miami-Dade County, that should be included in the designation 
because they (i) are occupied at the time of listing and contain the 
physical or biological features that are essential to the conservation 
of the species and that may require special management considerations, 
or (ii) are unoccupied at the time of listing and are essential for the 
conservation of the species;
    (d) Special management considerations or protection that may be 
needed in critical habitat areas we are proposing, including managing 
for the potential effects of climate change; and
    (e) What areas not occupied at the time of listing are essential 
for the conservation of the species. We particularly seek comments:
    (i) Regarding whether occupied areas are adequate for the 
conservation of the species;
    (ii) Providing specific information regarding whether or not 
unoccupied areas would, with reasonable certainty, contribute to the 
conservation of the species and contain at least one physical or 
biological feature essential to the conservation of the species; and
    (iii) Explaining whether or not unoccupied areas fall within the 
definition of ``habitat'' at 50 CFR 424.02 and why.
    (iv) We have identified 14 units in this proposal that were 
unoccupied at the time of listing that we find are essential to the 
conservation of the Miami tiger beetle. Please provide specific 
comments and information on:
    <bullet> Whether each of these units are essential to the 
conservation of the Miami tiger beetle and should be included in 
critical habitat,
    <bullet> whether there are specific units that are not essential 
and should not be included in critical habitat and why, and
    <bullet> whether there are any other specific areas not currently 
proposed that are essential to the conservation of the Miami tiger 
beetle that should be included in critical habitat.
    (3) Any additional areas occurring within the range of the species, 
i.e., South Florida, that should be included in the designation because 
they (a) are occupied at the time of listing and contain the physical 
and biological features that are essential to the conservation of the 
species and that may require special management considerations, or (b) 
are unoccupied at the time of listing and are essential for the 
conservation of the species.
    (4) Land use designations and current or planned activities in the 
subject areas and their possible impacts on proposed critical habitat.
    (5) Information on the projected and reasonably likely impacts of 
climate change on Miami tiger beetle and proposed critical habitat.
    (6) Information on the extent to which the description of probable 
economic impacts in the draft economic analysis is a reasonable 
estimate of the likely economic impacts; any probable economic, 
national security, or other relevant impacts of designating any area 
that may be included in the final designation, in particular, any 
impacts on small entities or families; and the benefits of including or 
excluding areas that exhibit these impacts.
    (7) Whether any specific areas we are proposing for critical 
habitat designation should be considered for exclusion under section 
4(b)(2) of the Act, and whether the benefits of potentially excluding 
any specific area outweigh the benefits of including that area under 
section 4(b)(2) of the Act. In particular for those for which you think 
we should exclude any additional areas, please provide credible 
information regarding the existence of a meaningful economic or other 
relevant impact supporting a benefit of exclusion.

[[Page 49947]]

    (8) Whether we could improve or modify our approach to designating 
critical habitat in any way to provide for greater public participation 
and understanding, or to better accommodate public concerns and 
comments.
    Please include sufficient information with your submission (such as 
scientific journal articles or other publications) to allow us to 
verify any scientific or commercial information you include. Please 
note that submissions merely stating support for, or opposition to, the 
action under consideration without providing supporting information, 
although noted, will not be considered in making a final critical 
habitat determination
    You may submit your comments and materials concerning this proposed 
rule by one of the methods listed in ADDRESSES. We request that you 
send comments only by the methods described in ADDRESSES.
    If you submit information via http://www.regulations.gov, your 
entire submission--including any personal identifying information--will 
be posted on the website. If your submission is made via a hardcopy 
that includes personal identifying information, you may request at the 
top of your document that we withhold this information from public 
review. However, we cannot guarantee that we will be able to do so. We 
will post all hardcopy submissions on http://www.regulations.gov.
    Comments and materials we receive, as well as supporting 
documentation we used in preparing this proposed rule, will be 
available for public inspection on http://www.regulations.gov.
    Because we will consider all comments and information we receive 
during the comment period, our final designation may differ from this 
proposal. Based on the new information we receive (and any comments on 
that new information), our final designation may not include all areas 
proposed, may include some additional areas that meet the definition of 
critical habitat, and may exclude some areas if we find the benefits of 
exclusion outweigh the benefits of inclusion.

Public Hearing

    Section 4(b)(5) of the Act provides for a public hearing on this 
proposal, if requested. Requests must be received by the date specified 
in DATES. Such requests must be sent to the address shown in FOR 
FURTHER INFORMATION CONTACT. We will schedule a public hearing on this 
proposal, if requested, and announce the date, time, and place of the 
hearing, as well as how to obtain reasonable accommodations, in the 
Federal Register and local newspapers at least 15 days before the 
hearing. For the immediate future, we will provide these public 
hearings virtually using webinars that will be announced on the 
Service's website, in addition to the Federal Register. The use of 
these virtual public hearings is consistent with our regulation at 50 
CFR 424.16(c)(3).

Previous Federal Actions

    On December 22, 2015, we proposed to list the Miami tiger beetle as 
an endangered species under the Act (80 FR 79533) in the Federal 
Register. On October 5, 2016, we published our final determination in 
the Federal Register (81 FR 68985) and added the Miami tiger beetle as 
an endangered species to the List of Endangered and Threatened Wildlife 
at 50 CFR 17.11(h). At the time of our proposal we determined that 
critical habitat was prudent, but not determinable because we lacked 
specific information on the impacts of our designation. In our final 
listing rule, we stated we were in the process of obtaining information 
on the impacts of the designation. All previous Federal actions are 
described in detail in the proposal to list the Miami tiger beetle as 
an endangered species under the Act (80 FR 79533, December 22, 2015). 
Additional information may be found in the final rule to list the Miami 
tiger beetle as an endangered species (81 FR 68985, October 5, 2016).

Critical Habitat

Background

    Critical habitat is defined in section 3 of the Act as:
    (1) The specific areas within the geographical area occupied by the 
species, at the time it is listed in accordance with the Act, on which 
are found those physical or biological features
    (a) Essential to the conservation of the species, and
    (b) Which may require special management considerations or 
protection; and
    (2) Specific areas outside the geographical area occupied by the 
species at the time it is listed, upon a determination that such areas 
are essential for the conservation of the species.
    Our regulations at 50 CFR 424.02 define the geographical area 
occupied by the species as an area that may generally be delineated 
around species' occurrences, as determined by the Secretary (i.e., 
range). Such areas may include those areas used throughout all or part 
of the species' life cycle, even if not used on a regular basis (e.g., 
migratory corridors, seasonal habitats, and habitats used periodically, 
but not solely, by vagrant individuals). Additionally, our regulations 
at 50 CFR 424.02 define the word ``habitat'' as follows: ``for the 
purposes of designating critical habitat only, habitat is the abiotic 
and biotic setting that currently or periodically contains the 
resources and conditions necessary to support one or more life 
processes of a species.''
    Conservation, as defined under section 3 of the Act, means to use 
and the use of all methods and procedures that are necessary to bring 
an endangered 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, may include regulated taking.
    Critical habitat receives protection under section 7 of the Act 
through the requirement that Federal agencies ensure, in consultation 
with the Service, that any action they authorize, fund, or carry out is 
not 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 also does not allow the 
government or public to access private lands. Such designation does not 
require implementation of restoration, recovery, or enhancement 
measures by non-Federal landowners. Where a landowner requests Federal 
agency funding or authorization for an action that may affect a listed 
species or critical habitat, the Federal agency would be required to 
consult with the Service under section 7(a)(2) of the Act. However, 
even if the Service were to conclude that the proposed activity would 
result in destruction or adverse modification of the critical habitat, 
the Federal action agency and the landowner are not required to abandon 
the proposed activity, or to restore or recover the species; instead, 
they must implement ``reasonable and prudent alternatives'' to avoid 
destruction or adverse modification of critical habitat.
    Under the first prong of the Act's definition of critical habitat, 
areas within the geographical area occupied

[[Page 49948]]

by the species at the time it was listed are included in a critical 
habitat designation if they contain physical or biological features (1) 
which are essential to the conservation of the species and (2) which 
may require special management considerations or protection. For these 
areas, critical habitat designations identify, to the extent known 
using the best scientific and commercial data available, those physical 
or biological features that are essential to the conservation of the 
species (such as space, food, cover, and protected habitat). In 
identifying those physical or biological features that occur in 
specific occupied areas, we focus on the specific features that are 
essential to support the life-history needs of the species, including, 
but not limited to, water characteristics, soil type, geological 
features, prey, vegetation, symbiotic species, or other features. A 
feature may be a single habitat characteristic or a more complex 
combination of habitat characteristics. Features may include habitat 
characteristics that support ephemeral or dynamic habitat conditions. 
Features may also be expressed in terms relating to principles of 
conservation biology, such as patch size, distribution distances, and 
connectivity.
    Under the second prong of the Act's definition of critical habitat, 
we can designate critical habitat in areas outside the geographical 
area occupied by the species at the time it is listed, upon a 
determination that such areas are essential for the conservation of the 
species. The implementing regulations at 50 CFR 424.12(b)(2) further 
delineate unoccupied critical habitat by setting out three specific 
parameters: (1) When designating critical habitat, the Secretary will 
first evaluate areas occupied by the species; (2) the Secretary will 
consider unoccupied areas to be essential only where a critical habitat 
designation limited to geographical areas occupied by the species would 
be inadequate to ensure the conservation of the species; and (3) for an 
unoccupied area to be considered essential, the Secretary must 
determine that there is a reasonable certainty both that the area will 
contribute to the conservation of the species and that the area 
contains one or more of those physical or biological features essential 
to the conservation of the species.
    Section 4 of the Act requires that we designate critical habitat 
based on the best scientific data available. Further, our Policy on 
Information Standards Under the Endangered Species Act (published in 
the Federal Register on July 1, 1994 (59 FR 34271)), the Information 
Quality Act (section 515 of the Treasury and General Government 
Appropriations Act for Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)), 
and our associated Information Quality Guidelines provide criteria, 
establish procedures, and provide guidance to ensure that our decisions 
are based on the best scientific data available. They require our 
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 we are determining which areas should be designated as 
critical habitat, our primary source of information is generally the 
information from the listing process for the species. Additional 
information sources may include any generalized conservation strategy, 
criteria, or outline that may have been developed for the species; the 
recovery plan for the species; articles in peer-reviewed journals; 
conservation plans developed by States and counties; scientific status 
surveys and studies; biological assessments; other unpublished 
materials; or experts' opinions or personal knowledge.
    As the regulatory definition of ``habitat'' reflects (50 CFR 
424.02), habitat is dynamic, and species may move from one area to 
another over time. We recognize that critical habitat designated at a 
particular point in time may not include all of the habitat areas that 
we may later determine are necessary for the recovery of the species. 
For these reasons, a critical habitat designation does not signal that 
habitat outside the designated area is unimportant or may not be needed 
for recovery of the species. Areas that are important to the 
conservation of the species, both inside and outside the critical 
habitat designation, will continue to be subject to: (1) Conservation 
actions implemented under section 7(a)(1) of the Act; (2) regulatory 
protections afforded by the requirement in section 7(a)(2) of the Act 
for Federal agencies to ensure their actions are not likely to 
jeopardize the continued existence of any endangered or threatened 
species; and (3) section 9 of the Act's prohibitions on taking any 
individual of the species, including taking caused by actions that 
affect habitat. Federally funded or permitted projects affecting listed 
species outside their designated critical habitat areas may still 
result in jeopardy findings in some cases. These protections and 
conservation tools will continue to contribute to recovery of the 
species. 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 (HCPs), or other species conservation planning 
efforts if new information available at the time of those planning 
efforts calls for a different outcome.

Prudency Determination

    Section 4(a)(3) of the Act, as amended, and implementing 
regulations (50 CFR 424.12) require that, to the maximum extent prudent 
and determinable, the Secretary shall designate critical habitat at the 
time the species is determined to be an endangered or threatened 
species. Our regulations (50 CFR 424.12(a)(1)) state that the Secretary 
may, but is not required to, determine that a designation would not be 
prudent in the following circumstances:
    (i) The species is threatened by taking or other human activity and 
identification of critical habitat can be expected to increase the 
degree of such threat to the species;
    (ii) The present or threatened destruction, modification, or 
curtailment of a species' habitat or range is not a threat to the 
species, or threats to the species' habitat stem solely from causes 
that cannot be addressed through management actions resulting from 
consultations under section 7(a)(2) of the Act;
    (iii) Areas within the jurisdiction of the United States provide no 
more than negligible conservation value, if any, for a species 
occurring primarily outside the jurisdiction of the United States;
    (iv) No areas meet the definition of critical habitat; or
    (v) The Secretary otherwise determines that designation of critical 
habitat would not be prudent based on the best scientific data 
available.
    As discussed in the final listing rule published on October 5, 2016 
(81 FR 68985), there is currently imminent threat of take attributed to 
collection or vandalism identified under Factor B for this species. 
However, we have determined that the identification and mapping of 
critical habitat is not expected to increase any such threat because 
the location of the two extant populations of the Miami tiger beetle 
are currently known to the scientific community and public. Further, in 
our proposed listing determination for this species, we determined that 
the present or threatened destruction, modification, or curtailment of 
habitat or range is a threat, and that those threats in some way can be 
addressed by section 7(a)(2) consultation measures. Also, the species 
occurs wholly in the jurisdiction of the

[[Page 49949]]

United States, and we are able to identify areas that meet the 
definition of critical habitat. Therefore, because none of the 
circumstances enumerated in our regulations at 50 CFR 424.12(a)(1) have 
been met and because the Secretary has not identified other 
circumstances for which this designation of critical habitat would be 
not prudent, we have determined that the designation of critical 
habitat is prudent for the Miami tiger beetle.

Physical or Biological Features Essential to the Conservation of the 
Species

    In accordance with section 3(5)(A)(i) of the Act and regulations at 
50 CFR 424.12(b), in determining which areas we will designate as 
critical habitat from within the geographical area occupied by the 
species at the time of listing, we consider the physical or biological 
features that are essential to the conservation of the species and that 
may require special management considerations or protection. The 
regulations at 50 CFR 424.02 define ``physical or biological features 
essential to the conservation of the species'' as the features that 
occur in specific areas and that are essential to support the life-
history needs of the species, including, but not limited to, water 
characteristics, soil type, geological features, sites, prey, 
vegetation, symbiotic species, or other features. A feature may be a 
single habitat characteristic or a more complex combination of habitat 
characteristics. Features may include habitat characteristics that 
support ephemeral or dynamic habitat conditions. Features may also be 
expressed in terms relating to principles of conservation biology, such 
as patch size, distribution distances, and connectivity. For example, 
physical features essential to the conservation of the species might 
include gravel of a particular size required for spawning, alkaline 
soil for seed germination, protective cover for migration, or 
susceptibility to flooding or fire that maintains necessary early-
successional habitat characteristics. Biological features might include 
prey species, forage grasses, specific kinds or ages of trees for 
roosting or nesting, symbiotic fungi, or a particular level of 
nonnative species consistent with conservation needs of the listed 
species. The features may also be combinations of habitat 
characteristics and may encompass the relationship between 
characteristics or the necessary amount of a characteristic essential 
to support the life history of the species.
    In considering whether features are essential to the conservation 
of the species, we may consider an appropriate quality, quantity, and 
spatial and temporal arrangement of habitat characteristics in the 
context of the life-history needs, condition, and status of the 
species. These characteristics 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, or 
rearing (or development) of offspring; and habitats that are protected 
from disturbance.
    We derive the specific physical or biological features essential 
for the Miami tiger beetle from studies of this species' habitat, 
ecology, and life history as described below. Additional information 
can be found in the final listing rule published in the Federal 
Register on October 5, 2016 (81 FR 68985).

Space for Individual and Population Growth and for Normal Behavior

    The Miami tiger beetle is endemic to pine rockland habitat within 
the Northern Biscayne Pinelands of the Miami Rock Ridge in Miami-Dade 
County in South Florida. Descriptions of this habitat and its 
associated native plant species are provided in the proposed listing 
rule published on December 22, 2015 (80 FR 79533) (see Habitat 
section). Additional discussion may be found in the final listing rule 
published on October 5, 2016 (81 FR 68985). The Miami tiger beetle 
requires open or sparsely vegetated sandy areas within pine rockland 
habitat for thermoregulation (regulation of body temperature), 
foraging, reproduction, and larval development.
    As a group, tiger beetles (Coleoptera: Cicindelidae) occupy 
ephemeral habitats where local extinction from habitat loss or 
degradation is common, so dispersal to establish new populations in 
distant habitat patches is a likely life history strategy for most 
species (Knisley 2015a, p. 10). Therefore, individuals of the species 
must be sufficiently abundant and occur within an appropriate dispersal 
distance to adjacent suitable habitat so they can repopulate areas 
following local extirpations. Barriers to dispersal can disrupt 
otherwise normal metapopulation dynamics and contribute to imperilment.
    Development and agriculture have reduced pine rockland habitat by 
90 percent in mainland south Florida. Pine rockland habitat decreased 
from approximately 183,000 ac (74,000 ha) in the early 1900s to only 
3,707 ac (1,500 ha) in 2014 (Possley et al. 2014, p. 154). The largest 
remaining intact pine rockland (approximately 5,716 ac (2,313 ha)) is 
Long Pine Key in Everglades National Park (Everglades). Outside of the 
Everglades, less than 2 percent of pine rocklands on the Miami Rock 
Ridge remain, and much of what is left are small remnants scattered 
throughout the Miami metropolitan area, isolated from other natural 
areas (Herndon 1998, p. 1; URS Corporation Southern 2007, p. 1).
    The extreme rarity of high-quality pine rockland habitats 
supporting the Miami tiger beetle elevates the importance of remnant 
sites that still retain some pine rockland species. We consider pine 
rockland habitat to be the primary habitat for the Miami tiger beetle.
    We do not have specific information regarding a minimum viable 
population size for the Miami tiger beetle or the amount of habitat 
needed to sustain a viable population. Recovery plans for Cicindela 
puritana (Puritan tiger beetle) and C. dorsalis dorsalis (Northeastern 
beach tiger beetle) consider a minimum viable population size to be at 
least 500-1,000 adults (Hill and Knisley 1993, p. 23; Hill and Knisley 
1994, p. 31). A minimum viable population size of 500 adults was 
estimated for the Salt Creek tiger beetle (Cicindela nevadica 
lincolniana) (79 FR 26014, May 6, 2014). The best available data 
regarding the minimum area and number of individuals necessary for a 
viable population for the Miami tiger beetle come from information 
regarding the closely related Highlands tiger beetle (Cicindelidia 
highlandensis); the information describes estimates of a minimum of 100 
adult Highlands tiger beetles in an area of at least 2.5-5.0 ac (1.0-
2.0 ha) (Knisley and Hill 2013, p. 42). This estimate is based on 
observations of population stability for the Highlands tiger beetle, as 
well as survey data and literature from other tiger beetle species 
(Knisley and Hill 2013, p. 42).
    The Miami tiger beetle requires open or sparsely vegetated sandy 
areas within pine rockland habitat to meet their life-history 
requirements, as well as adjacent undeveloped habitat to facilitate 
dispersal and protect core habitat. Therefore, based on the information 
in the previous paragraph, we identify pine rockland habitats of at 
least 2.5-5.0 ac (1.0-2.0 ha) in size as a necessary physical feature 
for this species.

Food, Water, Air, Light, Minerals, or Other Nutritional or 
Physiological Requirements

    Food--Miami tiger beetles are active diurnal predators that use 
their keen vision to detect movement of small

[[Page 49950]]

arthropods and run quickly to capture prey with their well-developed 
jaws (mandibles). Although we do not have specific information on Miami 
tiger beetle diets, observations by various entomologists indicate 
small arthropods, especially ants, are the most common prey for tiger 
beetles. Over 30 kinds of insects from many families have been 
identified as prey for tiger beetles, and scavenging is also common in 
some species (Knisley and Schultz 1997, pp. 39, 103; Willis 1967, pp. 
196-197). Ants were the most common prey of tiger beetles in Florida 
(Choate 1996, p. 2). Miami tiger beetle larvae are sedentary sit-and-
wait predators that capture small prey passing over or near (within a 
few inches (in) (centimeters (cm)) their burrows on the soil surface. 
Larvae prey on small arthropods, similar to adults. Alterations or 
reductions in the prey base through pesticide exposure could affect 
foraging in of Miami tiger beetles.
    Water--The Miami tiger beetle requires inland sandy pine rockland 
habitat that has moderately drained to well-drained terrain. Rainfall 
varies from an annual average over 64 in (163 cm) in the northwest 
portion of Miami-Dade County to between 48 and 56 in (122 and 143 cm), 
respectively, in the rest of the county (Service 1999, p. 3-167). The 
water table in the Miami Rock Ridge outside of the Everglades seldom 
reaches the surface (Service 1999, p. 3-167). The existence of larvae 
in shallow permanent burrows throughout their development makes them 
susceptible to changes in groundwater levels. The effects of climate 
change and sea level rise, which predict higher intensity storms, more 
erratic rainfall (i.e., alterations to the amount and seasonality and 
rainfall) and especially changes in water levels due to storm surge and 
salinization of the water table, could result in vegetation shifts that 
may impact the species. Based on this, we identify water (particularly 
appropriate hydrological regimes) as a necessary feature for the Miami 
tiger beetle to carry out its life processes.
    Light--The Miami tiger beetle requires open areas of pine rockland 
habitat with ample sunlight for behavioral thermoregulation, so they 
can successfully perform their normal activities, such as foraging, 
mating, and oviposition. Vegetation encroachment and lack of adequate 
pine rockland management threatens the amount of light necessary for 
the Miami tiger beetle. We identify light as a necessary feature for 
the Miami tiger beetle to carry out its life processes.
    Soil--The Miami tiger beetle is endemic to pine rockland habitat 
within the Miami Rock Ridge. The Miami Rock Ridge has oolitic limestone 
(composed of spherical grains packed tightly) at or very near the 
surface and solution holes occasionally from where the surface 
limestone is dissolved by organic acids. There is typically very little 
soil development, consisting primarily of accumulations of low-nutrient 
sand, marl, clayey loam, and organic debris found in solution holes, 
depressions, and crevices on the limestone surface (Florida Natural 
Areas Inventory (FNAI) 2010, p. 62). However, sandy pockets can be 
found at the northern end of the Miami Rock Ridge (Northern Biscayne 
Pinelands), beginning from approximately North Miami Beach and 
extending south to approximately SW 216th Street (Service 1999, p. 3-
162).
    These sandy substrates provide the appropriate nutrients, moisture 
regime, and soil chemistry necessary for Miami tiger beetle 
reproduction. Burrows in the sand are used for eggs and developing 
larvae. In addition these sandy areas support a community of insect 
prey that allows the species to persist. Soil compaction could impact 
the species and its habitat. Therefore, we identify substrates derived 
from calcareous limestone that provide habitat for the Miami tiger 
beetle to carry out its life processes to be a necessary feature for 
the Miami tiger beetle.
    Summary--Based on the best available information, we conclude that 
the Miami tiger beetle requires open sandy areas in pine rockland 
habitat with little to no vegetation for thermoregulation, foraging, 
egg-laying, and larval development. We identify these characteristics 
as necessary physical and biological features for the species.

Cover or Shelter

    The life cycle of the Miami tiger beetle occurs entirely within 
pine rocklands. Females place a single egg into a shallow burrow dug 
into the soil. The egg hatches, apparently after sufficient soil 
moisture, and the first instar larva digs a burrow at the site of 
oviposition (egg-laying). Larvae are closely associated with their 
burrows, which provide cover and shelter for anywhere from 2 months to 
1 year or more, depending on climate, food availability, and the number 
of cohorts per year (Knisley 2015b, p. 28). Larvae remain in their 
burrows until they are adults, only extending beyond the burrow 
entrance to subdue arthropod prey. The adult flight period for the 
Miami tiger beetle lasts approximately 5 months (mid-May to mid-
October) (Knisley 2015b, p. 27). Both larvae and adults are visual 
predators and require open habitat to locate prey. Open areas with 
dense vegetation no longer provide suitable habitat. However, 
vegetation adjacent to open sandy areas may also be important, as it 
may provide thermal refugia for the beetles to escape from high ground 
temperatures (Knisley 2014, p. 1). Miami tiger beetle habitat can also 
be impacted from trampling, which causes soil compaction and can lead 
to lethal impacts to adults or larvae or impacts to their habitat.
    Based on the best available information, we conclude that the Miami 
tiger beetle requires pine rocklands, specifically those containing 
open or sparsely vegetated sandy patches.

Sites for Breeding, Reproduction, or Rearing (or Development) of 
Offspring

    Miami tiger beetle reproduction and larval development occurs 
entirely within pine rocklands. Both larvae and adults occupy the same 
habitats--open sandy patches interspersed with vegetation. Vegetation 
encroachment into the open sandy habitat patches, barriers to 
dispersal, trampling of the surface soil, reductions in prey base, and 
collection of beetles are factors that may reduce the reproductive 
potential of the species. Therefore, based on the information above, we 
identify pine rockland habitats that can support the species growth, 
distribution, and population expansion as required for this species.

Habitats Representative of the Historical, Geographical, and Ecological 
Distributions of the Species

    The Miami tiger beetle continues to occur in pine rockland habitats 
that are protected from incompatible human-use, but these areas are 
only partially representative of the species' historical, geographical, 
and ecological distribution because its range within these habitats has 
been reduced. The species is still found in pine rockland habitats, 
with open sandy areas of at least 2.5-5.0 ac (1.0-2.0 ha) in size. 
Representative pine rocklands are located on Federal, local, and 
private conservation lands that implement conservation measures 
benefitting the beetle.
    Pine rockland is dependent on some degree of disturbance, most 
importantly from natural or prescribed fires (Loope and Dunevitz 1981, 
p. 5; Snyder et al. 2005, p. 1; Bradley and Saha 2009, p. 4; Saha et 
al. 2011, pp. 169-184; FNAI 2010, p. 62). These fires are a vital 
component in maintaining native vegetation and creating or maintaining 
open or sparsely vegetated sandy areas,

[[Page 49951]]

within this ecosystem. Fires have historically burned in intervals of 
approximately 3 to 7 years (FNAI 2010, p. 3) typically started by 
lightning strikes during the frequent summer thunderstorms (FNAI 2010, 
p. 3). Without fire, successional climax from tropical pineland to 
rockland hammock is rapid, and the open areas required by the species 
are encroached with vegetation and leaf litter. In addition, 
displacement of native species by invasive, nonnative plants often 
occurs.
    Mechanical control or thinning of pine rockland vegetation may be 
another means of maintaining pine rockland habitat, but it cannot 
entirely replace fire because it does not have the same benefits 
related to removal of leaf litter and nutrient cycling. In addition, it 
may lead to trampling of adult or larval tiger beetles. Natural and 
prescribed fire remains the primary and ecologically preferred method 
for maintaining pine rockland habitat.
    Hurricanes and other significant weather events can contribute to 
openings in the pine rockland habitat (FNAI 2010, p. 62) needed by the 
Miami tiger beetle; however, they can also be a source of significant 
and direct risk to the species. Given the few, isolated populations of 
the Miami tiger beetle within a location prone to storm influences 
(located approximately 5 miles (8 kilometers) from the coast), the 
species is at substantial risk from stochastic environmental events 
such as hurricanes, storm surges, and other extreme weather that can 
affect recruitment, population growth, and other population parameters. 
The substantial reduction in the historical range of the beetle in the 
past 80 years, and the few remaining populations, make the species less 
resilient to impacts than when its distribution was more widespread.
    Therefore, based on the information above, we identify pine 
rockland management through natural or prescribed fire, or other 
disturbance regimes that maintain pine rockland habitat, such as 
weather events, to be necessary for this species.

Summary of Essential Physical or Biological Features

    We derive the specific physical or biological features essential to 
the conservation of Miami tiger beetle from studies of the species' 
habitat, ecology, and life history. We have determined that the 
following physical or biological features are essential to the 
conservation of Miami tiger beetle:
    1. South Florida pine rockland habitat of at least 2.5 ac (1 ha) in 
size that is maintained by natural or prescribed fire or other 
disturbance regimes; and
    2. Open sandy areas within or directly adjacent to the south 
Florida pine rockland habitat with little to no vegetation that allows 
for or facilitates normal behavior and growth such as thermoregulation, 
foraging, egg-laying, larval development, and habitat connectivity, 
which promotes the overall distribution and expansion of the species.

Special Management Considerations or Protection

    When designating critical habitat, we assess whether the specific 
areas within the geographical area occupied by the species at the time 
of listing contain features which are essential to the conservation of 
the species and which may require special management considerations or 
protection. The features essential to the conservation of this species 
may require special management considerations or protection to reduce 
the following threats: Vegetation encroachment of pine rockland 
habitat; loss of pine rockland habitat due to development that further 
fragments or degrades the few remaining pine rockland parcels in Miami-
Dade County; collection of the species; climate change and sea level 
rise; pesticide exposure; and demographic and environmental 
stochasticity. These threats are exacerbated by having only two small 
populations in a restricted geographic range, making this species 
particularly susceptible to extinction in the foreseeable future. For a 
detailed discussion of threats, see Summary of Factors Affecting the 
Species in our proposed listing rule published in the Federal Register 
on December 22, 2015 (80 FR 79533). Additional information may be found 
in the final listing rule published on October 5, 2016 (81 FR 68985).
    Some of these threats can be addressed by special management 
considerations or protection while others (e.g., sea level rise, 
hurricanes, storm surge) are beyond the control of landowners and 
managers. However, even when landowners or land managers may not be 
able to control all the threats directly, they may be able to address 
the impacts of those threats.
    Destruction of rock pinelands for economic development has reduced 
pine rockland habitat on the Miami Rock Ridge outside of the Everglades 
by over 98 percent, and remaining habitat in this area is highly 
fragmented. The Miami tiger beetle occurs on a mix of privately and 
publicly owned lands, only some of which are managed for conservation. 
Any occurrences of the beetle on private land or non-conservation 
public land are vulnerable to the effects of habitat degradation if 
natural disturbance regimes are disrupted, because the species requires 
active management to keep the habitat functional in the absence of such 
disturbances. Prolonged lack of fire in pine rockland habitat leads to 
vegetation encroachment into the open or sparsely vegetated sandy areas 
that are required by the beetle. Further development and degradation of 
pine rocklands increases fragmentation and decreases the conservation 
value of the remaining functioning pine rockland habitat. In addition, 
pine rocklands are expected to be further degraded and fragmented due 
to anticipated sea level rise, which would fully or partially inundate 
some pine rocklands within the Miami Rock Ridge and cause increases in 
the salinity of the water table and soils resulting in vegetation 
shifts. Also, portions of the Richmond Pine Rocklands are proposed for 
commercial development and some existing pine rockland areas are 
projected to be developed for housing as the human population grows and 
adjusts to changing sea levels.
    Pesticides used in and around pine rockland habitat are a potential 
threat to the Miami tiger beetle through direct exposure to adults and 
larvae, secondary exposure from insect prey, overall reduction in 
availability of adult and larval prey, thus limiting foraging 
opportunities, or any combination of these factors. Based on Miami-Dade 
Mosquito Control's implementation of spray buffers around pine 
rocklands occupied by the Miami tiger beetle, mosquito control 
pesticides are not considered a current threat for the species. 
However, if these buffers were to change or Miami tiger beetles were 
found in habitat without restrictions of pesticide applications, then 
the threat of exposure would need to be reevaluated.
    The features essential to the conservation of the Miami tiger 
beetle (i.e., open or sparsely vegetated areas of pine rockland habitat 
that are at least 2.5-5.0 ac (1.0-2.0 ha) in size) may require special 
management considerations or protection to reduce threats. Actions that 
could ameliorate threats include, but are not limited to:
    (1) Restoration and management of existing and potential Miami 
tiger beetle habitats throughout the Miami Rock Ridge using prescribed 
fire and control of invasive, nonnative plants;
    (2) Protection of habitat adjacent to existing and new occurrences 
of the species to provide dispersal corridors, support the prey base, 
protect core

[[Page 49952]]

habitat, and allow for appropriate habitat management;
    (3) Use of pesticide spray buffers to prevent potential exposure to 
the species and probable limitation of foraging opportunities; and
    (4) Establishment of additional populations within the Miami Rock 
Ridge through captive rearing and translocation of laboratory-reared 
individuals from wild populations.

Criteria Used To Identify Critical Habitat

    As required by section 4(b)(2) of the Act, we use the best 
scientific data available to designate critical habitat. In accordance 
with the Act and our implementing regulations at 50 CFR 424.12(b), we 
review available information pertaining to the habitat requirements of 
the species and identify specific areas within the geographical area 
occupied by the species at the time of listing and any specific areas 
outside the geographical area occupied by the species to be considered 
for designation as critical habitat. We are proposing to designate 
critical habitat in areas within the geographical area occupied by the 
species at the time of listing in 2016. We also are proposing to 
designate specific areas outside the geographical area occupied by the 
species at the time of listing because we have determined that a 
designation limited to occupied areas would be inadequate to ensure the 
conservation of the species. Although we do not have definitive 
information that these areas were historically or are currently 
occupied by the Miami tiger beetle, they are within the historical 
range of the species, contain remnant south Florida pine rockland 
habitat and the essential physical or biological features, and have 
been determined to be essential for the conservation of the species, as 
further discussed below. We have determined that it is reasonably 
certain that the unoccupied areas will contribute to the conservation 
of the species and contain one or more of the physical or biological 
features that are essential to the conservation of the species. We have 
also determined that the unoccupied areas fall within the regulatory 
definition of ``habitat'' at 50 CFR 424.02 since they have the abiotic 
and biotic features that currently or periodically contain the 
resources and conditions necessary to support one or more life 
processes of the Miami tiger beetle.
    The historical range of the Miami tiger beetle is limited to Miami-
Dade County, Florida, specifically within the Northern Biscayne 
Pinelands of the Miami Rock Ridge. Over 98 percent of the Miami Rock 
Ridge pine rocklands outside of the Everglades has been lost to 
development, reducing the current range of the Miami tiger beetle to 
the southern portion of the Northern Biscayne Pinelands, in the 
Richmond Pine Rocklands and Nixon Smiley Pineland Preserve.
    We anticipate that recovery will require not only continued 
protection of the remaining extant populations and remnant pine 
rockland habitat but also establishment of populations in additional 
areas of Miami-Dade County to ensure there are adequate numbers of 
beetles and stable populations occurring over the entire geographic 
range of the Miami tiger beetle. This will help to reduce the chance 
that catastrophic events, such as storms, will simultaneously affect 
all known populations.
    The two extant Miami tiger beetle populations are small and at risk 
of adverse effects from reduced genetic variation, an increased risk of 
inbreeding depression, and reduced reproductive output. In addition, 
the two populations are isolated from each other, decreasing the 
likelihood that they could be naturally reestablished if extirpation 
from one location would occur.
    In selecting areas to propose for critical habitat designation, we 
used the conservation principles of the ``three R's'': Resiliency, 
redundancy, and representation (Shaffer and Stein 2000, entire) for 
conserving imperiled species. Resiliency is the ability to sustain 
populations through the natural range of favorable and unfavorable 
conditions. Redundancy ensures an adequate number of sites with 
resilient populations such that the species has the ability to 
withstand catastrophic events. Representation ensures adaptive capacity 
within a species and allows it to respond to environmental changes. 
This can be facilitated by conserving not just genetic diversity, but 
also the species' associated habitat type variation. Implementation of 
this methodology has been widely accepted as a reasonable conservation 
strategy (Tear et al. 2005, p. 841).
    In order to ensure sufficient representation for the Miami tiger 
beetle, we described the physical and biological features (as discussed 
above) and identified areas of habitat that contain at least one or 
more of the features to provide for reintroduction and expansion of the 
Miami tiger beetle. Redundancy is currently low as only two populations 
remain, both on remnant pine rockland sites. Redundancy can be improved 
through the introduction of additional populations of the Miami tiger 
beetle at other pine rockland sites. However, throughout the species' 
range, the amount of suitable remaining pine rockland is limited (low 
resiliency), and much of the remaining habitat may be significantly 
altered due to the effects of climate change over the next century. 
Therefore, we reviewed available sites containing pine rockland habitat 
within the historical range of the species and evaluated each site for 
its potential conservation contribution based on quality of habitat, 
spatial arrangement relative to the two extant populations and each 
other, and existing protections and management of the habitat and sites 
to determine additional areas that are essential for the Miami tiger 
beetle's conservation.
Sources of Data To Identify Critical Habitat Boundaries
    We have determined that the areas known to be occupied at the time 
of listing should be proposed for critical habitat designation. 
However, recognizing that occupied habitat alone is not adequate for 
the conservation of the Miami tiger beetle, we also used habitat and 
historical occurrence data to identify the historical range of the 
species and necessary habitat features to help us determine which 
unoccupied habitat areas are essential for the conservation of the 
species. To determine the general extent, location, and boundaries of 
critical habitat, the Service used Esri ArcGIS mapping software for 
mapping and calculating areas (Albers Conical Equal Area (Florida 
Geographic Data Library), North American Datum of 1983 (NAD 83) High 
Accuracy Reference Network (HARN)) along with the following spatial 
data layers:
    (1) Historical and current records of Miami tiger beetle 
occurrences and distributions found in publications, reports, personal 
communications, and associated voucher specimens housed at museums and 
private collections (Knisley 2015b, entire);
    (2) Geographic information system (GIS) data showing the location 
and extent of documented occurrences of pine rockland habitat 
(Cooperative Land Cover Version 3.3. FWC and FNAI, 2018);
    (3) Aerial imagery (Esri ArcGIS online basemap World Imagery. South 
Florida Water Management District GIS Services, Earthstar Geographics, 
Miami-Dade County, Florida Department of Environmental Protection,

Agency, National Park Service, U.S. Department of Agriculture (USDA). 
2019.; and
    (4) GIS data depicting soils and to determine the presence of 
physical or biological features (U.S. Department of Agriculture 2020).
    When designating critical habitat, we consider future recovery 
efforts and conservation of the species. We have determined that all 
currently known occupied habitat should be proposed for critical 
habitat designation because any further degradation or loss of the 
extant populations or occupied habitat would increase the Miami tiger 
beetle's susceptibility to local extirpation and ultimately extinction. 
The species occurs in two populations, Richmond and Nixon Smiley, 
separated from each other by approximately 3.1 mi (5 km) of urban 
development.
    We are also including pine rockland habitat within the Richmond 
Pine Rocklands directly adjacent to sites with documented occurrences 
in the Richmond population. Due to their proximity to documented 
occurrences, the continuity of habitat, and presence of all of the 
physical or biological features, we have included these acres as part 
of the occupied habitat complex for this unit in accordance with 50 CFR 
424.12(d). Additionally, we have determined these areas are essential 
for the conservation of the species because they protect the occupied 
sites within the Richmond population, provide dispersal corridors for 
the Richmond population, provide potential habitat for population 
expansion, and support prey-base populations. These areas are important 
to ensure redundancy for the species, and they improve the species' 
viability.
    Lastly, we are including other suitable or potentially suitable 
pine rockland fragments outside of the Richmond Pine Rocklands and 
Nixon Smiley Pineland Preserve that are located within the beetle's 
historical range along the Northern Biscayne Pinelands of the Miami 
Rock Ridge but are not known to be currently occupied by the species. 
With only two known occupied areas, we have determined that these areas 
are essential for the conservation of the species because they will 
enable the establishment of new populations in additional areas that 
more closely approximate its historical distribution. Establishment of 
new populations will help ensure that there are adequate numbers of 
beetles in multiple populations over a wide geographic area, so that 
catastrophic events, such as storms, would be less likely to 
simultaneously affect all known populations.
    The best available data regarding the minimum area and number of 
individuals necessary for a viable population come from information 
regarding the Highlands tiger beetle; the information describes 
estimates of a minimum of 100 adult Highlands tiger beetles in an area 
of at least 2.5-5.0 ac (1.0-2.0 ha) (Knisley and Hill 2013, p. 42). 
This estimate is based on observations of population stability for the 
Highlands tiger beetle, as well as survey data and literature from 
other tiger beetle species. From the remaining suitable or potentially 
suitable pine rockland fragments that were delineated for the Miami 
Rock Ridge, we excluded fragments below the 2.5-ac (1.0-ha) minimum 
area for a viable population. As such we evaluated the remaining 
unoccupied pine rockland habitat within and directly adjacent to the 
Northern Biscayne Pinelands of the Miami Rock Ridge to identify remnant 
pine rocklands with the highest quality habitat potential (i.e., 
actively managed to support pine rocklands) and of sufficient size 
(patches at least 2.5 ac (1.0 ha)) to provide for the conservation of 
the Miami tiger beetle.

Areas Occupied at the Time of Listing

    The two occupied critical habitat units were delineated around the 
only remaining extant Miami tiger beetle populations. They include the 
mapped extent of the populations that contain the physical or 
biological features essential to the conservation of the Miami tiger 
beetle. The two occupied units account for approximately 1,572 ac (636 
ha) or 80 percent of the proposed designation of critical habitat for 
the Miami tiger beetle.
    The delineation of proposed critical habitat included the area 
containing the extant populations based on occurrence records as well 
as all suitable habitat directly adjacent to those areas to allow for 
the continued protection and management of pine rockland habitat and to 
meet the needs of the species. Given the Miami tiger beetle's 
dependence on disturbance (i.e., fires, storms, or mechanical 
treatments) to maintain optimal habitat, the amount and location of 
optimal habitat is temporally and spatially dynamic.

Areas Outside of the Geographical Range at the Time of Listing

    The Miami tiger beetle has been extirpated from its type-locality 
(the place where the species was first discovered) in North Miami and 
is historically unknown from any other locations. In addition to 
including areas of the two extant populations (Richmond Pine Rocklands 
and Nixon Smiley Pineland Preserve) in proposed critical habitat, we 
are proposing 14 unoccupied critical habitat units that we have 
determined are essential to the conservation of the Miami tiger beetle. 
These areas contain pine rockland habitat within the historical range 
in the Northern Biscayne Pinelands on the Miami Rock Ridge and 
encompass approximately 405 ac (164 ha) or 20 percent of proposed 
critical habitat. As discussed above, we have determined that recovery 
requires additional populations be established in high quality pine 
rockland habitat that is protected and actively managed. Following a 
review of available sites containing pine rockland habitat within the 
historical range of the species, we evaluated each site for its 
potential conservation contribution based on quality of habitat, 
spatial arrangement relative to the two extant populations and each 
other, and existing protections and management. This review led to our 
determination that the most viable sites for introduction and 
conservation of the Miami tiger beetle are the 14 unoccupied sites 
identified in this proposal. As a result, we concluded that these 14 
sites, which each contain all of the physical or biological features, 
have the highest probability for the conservation of the species and 
are essential to the conservation of the species. Thus, we are 
proposing them as critical habitat for the Miami tiger beetle.
    We used the best available data to delineate existing pine rockland 
habitat units that are of sufficient size to support introduced 
populations of Miami tiger beetles and that are spatially configured to 
support metapopulation dynamics and to minimize adverse impacts from 
stochastic events. In identifying these areas, we considered the 
following refining criteria:
    (1) Areas of sufficient size to support ecosystem processes for 
populations of the Miami tiger beetle. The best available information 
indicates that appropriately sized units should be at a minimum 2.5-5.0 
ac (1.0-2.0 ha). Large contiguous parcels of habitat are more likely to 
be resilient to ecological processes of disturbance and are more likely 
to support a viable population of the Miami tiger beetle. The 
unoccupied areas selected ranged from 7 ac (3 ha) in size to 89 ac (36 
ha).
    (2) Areas to maintain connectivity of habitat to allow for 
population expansion. Isolation of habitat can prevent recolonization 
of the Miami tiger beetle and result in local extirpation and 
ultimately extinction. To ameliorate the dangers associated

[[Page 49954]]

with small populations or limited distributions, we have identified 
areas of critical habitat that will allow for the natural expansion of 
populations or support reintroductions.
    (3) Restored pine rockland habitats may allow the Miami tiger 
beetle to disperse, recolonize, or expand from areas already occupied 
by the beetle. These restored areas generally are habitats within or 
adjacent to pine rocklands that have been affected by natural or 
anthropogenic factors but retain the essential physical or biological 
features that make them suitable for the beetle. These areas would help 
offset the anticipated loss and degradation of habitat occurring or 
expected from natural succession in the absence of disturbance, effects 
of climate change (such as sea level rise), or development.

Summary

    In summary, for areas within the geographical area occupied by the 
species at the time of listing, we delineated critical habitat unit 
boundaries using the following criteria:
    (1) Evaluated habitat suitability of pine rockland habitat within 
the geographical area occupied at the time of listing (current), and 
selected those areas that contain all of the physical or biological 
features to support life-history functions essential for conservation 
of the species;
    (2) Identified open sandy areas directly adjacent to occupied areas 
and with little to no vegetation that allow for or facilitate normal 
behavior and growth of the Miami tiger beetle, such as 
thermoregulation, foraging, egg-laying, larval development, and habitat 
connectivity, and which promote the overall distribution and expansion 
of the species.
    The result was the inclusion of two units of critical habitat 
occupied by the Miami tiger beetle. Approximately 1,052 ac (426 ha) or 
73 percent of the occupied units are existing critical habitat for 
other species.
    For areas outside the geographical area occupied by the species at 
the time of listing, we delineated critical habitat unit boundaries 
using the following criteria:
    (1) Areas with pine rockland habitat that contained the essential 
physical or biological features and were of sufficient size to support 
introduced populations of Miami tiger beetles;
    (2) Areas that are spatially configured to support metapopulation 
dynamics, minimize adverse impacts from stochastic events, and maintain 
representation of the historical range of the species.
    The result was the inclusion of 14 units of critical habitat not 
occupied by the Miami tiger beetle at the time of listing. These 14 
units encompass approximately 405 ac (164 ha) or 20 percent of proposed 
critical habitat. All 14 units are either publicly owned or privately 
owned conservation lands (i.e., Porter Pineland Preserve, which is 
owned and managed by the Audubon Society).
    When determining proposed critical habitat boundaries, we made 
every effort to avoid including developed areas such as lands covered 
by buildings, pavement, and other structures because such lands lack 
physical or biological features necessary for the Miami tiger beetle. 
The scale of the maps we prepared under the parameters for publication 
within the Code of Federal Regulations may not reflect the exclusion of 
such developed lands. Any such lands inadvertently left inside critical 
habitat boundaries shown on the maps of this proposed rule have been 
excluded by text in the proposed rule and are not proposed for 
designation as critical habitat. Therefore, if the critical habitat is 
finalized as proposed, a Federal action involving these lands would not 
trigger section 7 consultation with respect to critical habitat and the 
requirement of no adverse modification unless the specific action would 
affect the essential physical or biological features in the adjacent 
critical habitat.
    We are proposing for designation as critical habitat those lands 
that we have determined are occupied at the time of listing and which 
contain the physical or biological features to support life-history 
processes essential to the conservation of the species, and lands 
outside of the geographical area occupied at the time of listing that 
we have determined are essential for the conservation of the Miami 
tiger beetle.
    The critical habitat designation is defined by the maps, as 
modified by any accompanying regulatory text, presented at the end of 
this document in the rule portion. We include more detailed information 
on the boundaries of the critical habitat designation in the preamble 
of this document. We will make shapefiles of the critical habitat units 
available to the public on http://www.regulations.gov at Docket No. 
FWS-R4-ES-2021-0053, and on our internet site www.fws.gov/verobeach/.

Proposed Critical Habitat Designation

    We are proposing 16 units as critical habitat for the Miami tiger 
beetle. The critical habitat areas we describe below constitute our 
current best assessment of areas that meet the definition of critical 
habitat for the Miami tiger beetle. Table 1 shows each critical habitat 
unit, its occupancy by the Miami tiger beetle at the time it was listed 
under the Act, and the extent of overlap with critical habitat 
previously designated for other federally listed species.

    Approximately 73 percent (1,440 ac (583 ha)) of the critical 
habitat proposed for the Miami tiger beetle overlaps with currently 
designated Federal critical habitat for the Carter's small-flowered 
flax (Linum carteri var. carteri), the Florida brickell-bush 
(Brickellia mosieri), Bartram's scrub-hairstreak butterfly (Strymon 
acis bartrami), and the Florida leafwing butterfly (Anaea troglodyta 
floridalis). Further, approximately 4 percent (17 ac (7 ha)) of 
unoccupied critical habitat proposed is unique to the Miami tiger 
beetle, i.e., does not overlap with existing designated Federal 
critical habitat. Please refer to Table 1 above for the area of overlap 
with other federally designated critical habitat and to specific unit 
descriptions below for which currently designated Federal critical 
habitat overlaps with each proposed critical habitat unit for the Miami 
tiger beetle.
    Tables 2 and 3 below show the approximate land ownership for each 
critical habitat unit and the proportion of critical habitat for each 
landownership category, respectively. All but 1 ac (0.6 ha) of the area 
proposed for designation is either publicly or privately owned for 
conservation.

    In addition, over half of the proposed critical habitat for the 
Miami tiger beetle (1,219 ac (493 ha) or 62 percent) is under a Miami-
Dade County Natural Forest Communities (NFC) designation. Miami-Dade 
County's NFC designation enacts regulations on habitat alterations to 
minimize damage to and protect environmentally sensitive forest lands,

[[Page 49956]]

including pine rocklands. NFC regulations are designed to prevent 
clearing or destruction of native vegetation within preserved areas. 
Please see the unit descriptions below for the specific amount of each 
unit that is enrolled in the NFC program.
    We present brief descriptions of each proposed critical habitat 
units and the justification for why each meets the definition of 
critical habitat for the Miami tiger beetle, below.

Unit 1: Trinity Pineland

    Unit 1 consists of approximately 10 ac (4 ha) of State-owned land 
in Miami-Dade County. The unit is within the historical range of the 
Miami tiger beetle, although we are not aware of any records of 
historical occupancy of the unit. This unit includes pine rockland 
habitat within the Northern Biscayne Pinelands of the Miami Rock Ridge. 
This unit includes all the physical or biological features essential 
for the conservation of the species and is protected and actively 
managed to maintain a healthy pine rockland habitat.
    This unit is currently unoccupied by the Miami tiger beetle but is 
essential for the conservation of the species because it serves to 
protect habitat needed to recover the species, reestablish wild 
populations within the historical range of the species, and maintain 
populations throughout the historical distribution of the species in 
Miami-Dade County. It also provides habitat for recovery in the case of 
stochastic events, should the Miami tiger beetle be extirpated from one 
of its current locations. Given this unit contains essential habitat 
features (all of the physical or biological features), is protected and 
actively managed, and has an appropriate spatial distribution falling 
within the range of the species, we are reasonably certain that the 
lands and habitat within this unit will contribute to the conservation 
of the Miami tiger beetle.
    The Natural Areas Management Division of Miami-Dade County Parks, 
Recreation and Open Spaces Department conducts nonnative species 
control, prescribed fire, and mechanical vegetation treatments on lands

populations within the historical range of the species, and maintain 
populations throughout the historical distribution of the species in 
Miami-Dade County. It also provides habitat for recovery in the case of 
stochastic events, should the Miami tiger beetle be extirpated from one 
of its current locations. Given this unit contains essential habitat 
features (all of the physical or biological features), is protected and 
actively managed, and has an appropriate spatial distribution falling

Unit 12: Nixon Smiley Pineland Preserve

    Unit 12 consists of approximately 117 ac (47 ha) of county-owned 
lands in Miami-Dade County. This unit was occupied at the time of 
listing and is currently occupied by the Miami tiger beetle. While 
surveys of this site have been inconsistent in level of effort, timing, 
and frequency, they have primarily focused on the habitat previously 
known to be occupied: The open, sandy areas on the western half of the 
property.
    This occupied habitat contains all of the physical or biological 
features, including pine rockland habitat (of sufficient size) with 
open or sparsely vegetated sandy areas that allow for thermoregulation, 
foraging, egg-laying, larval development, species dispersal, and 
population expansion, and natural or artificial disturbance regimes. 
The physical or biological features in this unit are protected and 
actively managed to maintain healthy pine rockland habitat. They may 
require additional special management considerations or protection to 
address threats of habitat loss and fragmentation, inadequate fire 
management, vegetation encroachment, collection, small population size, 
and sea level rise. In some cases, there are management actions being 
implemented to reduce some of these threats, and continued coordination 
with our partners and landowners are ongoing to implement needed 
actions. This unit is occupied by one of two extant populations of 
Miami tiger beetle, contains essential habitat features (all of the 
physical or biological features), is protected and actively managed, 
and has an appropriate spatial distribution falling within the range of 
the species.

112 ac (47 ha) or 96 percent of Unit 12 is enrolled in the NFC program.

Unit 13: Camp Matecumbe

    Unit 13 consists of approximately 81 ac (33 ha) of State (76 ac (31 
ha)) and county (5 ac (2 ha)) owned lands in Miami-Dade County. The 
unit is within the historical range of the Miami tiger beetle, although 
we are not aware of any records of historical occupancy of the unit. 
This unit includes remaining pine rockland habitat in the Northern

    All but 4 ac (1 ha) of Unit 13 overlaps with designated critical 
habitat for Bartram's scrub-hairstreak butterfly, Carter's small-
flowered flax, and Florida brickell-bush. Additionally, approximately 
62 ac (25 ha) or 77 percent of Unit 13 is enrolled in the NFC program.

Unit 14: Richmond Pine Rocklands

    Unit 14 consists of approximately 1,455 ac (589 ha) in Miami-Dade 
County. Landownership in this unit is split among Federal (488 ac (198 
ha)), county (844 ac (341 ha)), and private (123 ac (50 ha)). This unit 
is currently occupied by the Miami tiger beetle, which has been 
documented from four contiguous parcels within the Richmond Pine 
Rocklands: Zoo Miami Pine Rockland Preserve (Zoo Miami), Larry and 
Penny Thompson Park, U.S. Coast Guard, and University of Miami's Center 
for Southeastern Tropical Advanced Remote Sensing property (CSTARS). 
Miami tiger beetles within the four contiguous occupied parcels in the 
Richmond population are within close proximity to each other with 
connecting patches of habitat with few or no barriers between parcels. 
Given the contiguous habitat with few barriers to dispersal, frequent 
adult movement among individuals is likely, and the occupied Richmond 
parcels probably represent a single population (Knisley 2015b, p. 10).
    The unit also includes areas of pine rockland habitat containing 
all of the physical and biological features essential to the 
conservation of the species that are adjacent to sites with documented 
occurrences. The complex, including these parcels, contains all of the 
essential features (physical or biological features)--including pine 
rockland habitat (of sufficient size) with open or sparsely vegetated 
sandy areas that allow for thermoregulation, foraging, egg-laying, 
larval development, species dispersal, and population expansion, and 
natural or artificial disturbance regimes. The complex as a whole 
protects the occupied sites within the Richmond population, provides 
dispersal corridors for the Richmond population, provides potential 
habitat for population expansion, and supports prey-base populations. 
Being only one of two sites known to be currently occupied by the Miami 
tiger beetle, this complex is important to the Miami tiger beetle to 
ensure redundancy for the species and to contribute to the species' 
viability.
    The physical or biological features in this unit may require 
additional special management considerations or protection to address 
threats of habitat loss and fragmentation, inadequate fire management, 
vegetation encroachment, collection, small population size, and sea 
level rise. In some cases, these threats are being addressed or 
coordinated with our partners and landowners to implement needed 
actions.
    Approximately 776 ac (314 ha) or 53 percent of Unit 14 is enrolled 
in the NFC program. In addition, of the approximately 1,455 ac (589 ha) 
of critical habitat proposed for the Miami tiger beetle in Unit 14, 
about 937 ac (379 ha) overlap with designated critical habitat for 
Bartram's scrub-hairstreak butterfly, Florida leafwing butterfly, 
Carter's small-flowered flax, and Florida brickell-bush. Therefore, 
approximately 518 ac (210 ha) of proposed critical

[[Page 49960]]

habitat in Unit 14 is unique to the Miami tiger beetle.

Unit 15: Calderon Pineland

    Unit 15 consists of approximately 14 ac (6 ha) of county-owned 
lands in Miami-Dade County. The unit is within the historical range of 
the Miami tiger beetle, although we are not aware of any records of 
historical occupancy of the unit. This unit includes remaining pine 
rockland habitat in the Northern Biscayne Pinelands of the Miami Rock 
Ridge. This unit includes all the physical or biological features 
essential to the conservation of the species and is protected and 
actively managed to maintain healthy pine rockland habitat.
    This unit is currently unoccupied by the Miami tiger beetle but is

    The entirety of Unit 15 overlaps with designated critical habitat 
for Florida brickell-bush. Additionally, approximately 9 ac (4 ha) or 
64 percent of Unit 15 is enrolled in the NFC program.

Unit 16: Porter Pineland Preserve

    Unit 16 consists of approximately 7 ac (3 ha) of privately owned 
lands in Miami-Dade County. The unit is within the historical range of

Effects of Critical Habitat Designation

Section 7 Consultation

    Section 7(a)(2) of the Act requires Federal agencies, including the 
Service, to ensure that any action they fund, authorize, or carry out 
is not likely to jeopardize the continued existence of any endangered 
species or threatened species or result in the destruction or adverse 
modification of designated critical habitat of such species. In 
addition, section 7(a)(4) of the Act requires Federal agencies to 
confer with the Service on any agency action which is likely to 
jeopardize the continued existence of any species proposed to be listed 
under the Act or result in the destruction or adverse modification of 
proposed critical habitat.
    We published a final rule revising the definition of destruction or 
adverse modification on August 27, 2019 (84 FR 44976). Destruction or 
adverse modification means a direct or indirect alteration that 
appreciably diminishes the value of critical habitat as a whole for the 
conservation of a listed species.
    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. Examples of actions that are subject to the 
section 7 consultation process are actions on State, Tribal, local, or 
private lands that require a Federal permit (such as a permit from the 
Corps under section 404 of the Clean Water Act (33 U.S.C. 1251 et seq.) 
or a permit from the Service under section 10 of the Act) or that 
involve some other Federal action (such as funding from the Federal 
Highway Administration, Federal Aviation Administration, or the Federal 
Emergency Management Agency). 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 carried out 
by a Federal agency--do not require section 7 consultation.
    Compliance with the requirements of section 7(a)(2) is documented 
through our 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 that may affect, and 
are likely to adversely affect, listed species or critical habitat.
    When we issue a biological opinion concluding that a project is 
likely to jeopardize the continued existence of a listed species and/or 
destroy or adversely modify critical habitat, we provide reasonable and 
prudent alternatives to the project, if any are identifiable, that 
would avoid the likelihood of jeopardy and/or destruction or adverse 
modification of critical habitat. We define ``reasonable and prudent 
alternatives'' (at 50 CFR 402.02) as alternative actions identified 
during consultation that:
    (1) Can be implemented in a manner consistent with the intended 
purpose of the action,
    (2) Can be implemented consistent with the scope of the Federal 
agency's legal authority and jurisdiction,
    (3) Are economically and technologically feasible, and
    (4) Would, in the Service Director's opinion, avoid the likelihood 
of jeopardizing the continued existence of the listed species and/or 
avoid the likelihood of destroying or adversely modifying 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

[[Page 49961]]

reasonable and prudent alternative are similarly variable.
    Regulations at 50 CFR 402.16 set forth requirements for Federal 
agencies to reinitiate formal consultation on previously reviewed 
actions. These requirements apply when the Federal agency has retained 
discretionary involvement or control over the action (or the agency's 
discretionary involvement or control is authorized by law) and, if 
subsequent to the previous consultation: (1) If the amount or extent of 
taking specified in the incidental take statement is exceeded; (2) if 
new information reveals effects of the action that may affect listed 
species or critical habitat in a manner or to an extent not previously 
considered; (3) if the identified action is subsequently modified in a 
manner that causes an effect to the listed species or critical habitat 
that was not considered in the biological opinion; or (4) if a new 
species is listed or critical habitat designated that may be affected 
by the identified action. In such situations, Federal agencies 
sometimes may need to request reinitiation of consultation with us, but 
the regulations also specify some exceptions to the requirement to 
reinitiate consultation on specific land management plans after 
subsequently listing a new species or designating new critical habitat. 
See the regulations for a description of those exceptions.

Application of the ``Destruction or Adverse Modification'' Standard

    The key factor related to the destruction or adverse modification 
determination is whether implementation of the proposed Federal action 
directly or indirectly alters the designated critical habitat in a way 
that appreciably diminishes the value of the critical habitat as a 
whole for the conservation of the listed species. As discussed above, 
the role of critical habitat is to support physical or biological 
features essential to the conservation of a listed species and provide 
for the conservation of the species.
    Section 4(b)(8) of the Act requires us to briefly evaluate and 
describe, in any proposed or final regulation that designates critical 
habitat, activities involving a Federal action that may violate section 
7(a)(2) of the Act by destroying or adversely modifying such habitat, 
or that may be affected by such designation.
    Activities that the Service may, during a consultation under 
section 7(a)(2) of the Act, consider likely to destroy or adversely 
modify critical habitat, or activities that may affect critical 
habitat, when carried out, funded, or authorized by a Federal agency, 
should result in consultation for the Miami tiger beetle. These 
activities include, but are not limited to:
    (1) Actions that would significantly alter the hydrology or 
substrate, such as ditching or filling. Such activities may include, 
but are not limited to, road construction or maintenance, and 
residential, commercial, or recreational development.
    (2) Actions that would significantly alter vegetation structure or 
composition, such as preventing the ability to conduct prescribed 
burns, residential and commercial development, and recreational 
facilities and trails.
    (3) Actions that would introduce chemical pesticides into the pine 
rockland ecosystem in a manner that impacts the Miami tiger beetle. 
Such activities may include but are not limited to mosquito control and 
agricultural pesticide applications.
    (4) Actions that would introduce nonnative species that would 
significantly alter vegetation structure or composition or the life 
history of the Miami tiger beetle. Such activities may include, but are 
not limited to, release of parasitic or predator species (flies or 
wasps) for use in agriculture-based biological control programs.

Exemptions

Application of Section 4(a)(3) of the Act

    Section 4(a)(3)(B)(i) of the Act (16 U.S.C. 1533(a)(3)(B)(i)) 
provides that: ``The Secretary shall not designate as critical habitat 
any lands or other geographical areas owned or controlled by the 
Department of Defense (DoD), or designated for its use, that are 
subject to an integrated natural resources management plan (INRMP) 
prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if the 
Secretary determines in writing that such plan provides a benefit to 
the species for which critical habitat is proposed for designation.'' 
No DoD lands with a completed INRMP are within the proposed critical 
habitat designation.
    We are not aware of any DoD lands within the boundaries of the 
proposed designation or that would be directly affected by the 
designation if finalized as proposed. We have determined that the 
Corps, a branch of the DoD, retains ownership over a 121-ac (49-ha) 
parcel proposed for designation of critical habitat in Unit 14; of this 
parcel, 85 ac (34 ha) are forested but not managed for preservation of 
natural resources. These Corps lands are not considered a military 
instillation under the Sikes Act subject to an INRMP, so they do not 
meet the standards of section 4(a)(3)(B)(i) of the Act. As a result, we 
are not exempting any lands from this designation of critical habitat 
for the Miami tiger beetle pursuant to section 4(a)(3)(B)(i) of the 
Act.

Consideration of Impacts Under Section 4(b)(2) of the Act

    Section 4(b)(2) of the Act states that the Secretary shall 
designate and make revisions to critical habitat 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 we determine 
that the benefits of such exclusion outweigh the benefits of specifying 
such area as part of the critical habitat, unless we determine, 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 statute on its face, as well 
as the legislative history, are clear that the Secretary has broad 
discretion regarding which factor(s) to use and how much weight to give 
to any factor. Under section 4(b)(2) of the Act, we may exclude an area 
from designated critical habitat based on economic impacts, impacts on 
national security, or any other relevant impacts. In considering 
whether to exclude a particular area from the designation, we identify 
the benefits of including the area in the designation, identify the 
benefits of excluding the area from the designation, and evaluate 
whether the benefits of exclusion outweigh the benefits of inclusion. 
If the analysis indicates that the benefits of exclusion outweigh the 
benefits of inclusion, the Secretary may exercise discretion to exclude 
the area only if such exclusion would not result in the extinction of 
the species. We have not proposed any areas for exclusion from critical 
habitat for the Miami tiger beetle. However, the final decision on 
whether to exclude any areas will be based on the best scientific data 
available at the time of the final designation, including information 
obtained during the comment period and information about the economic 
impact of designation. Accordingly, we have prepared a draft economic 
analysis concerning the proposed critical habitat designation, which is 
available for review and comment (see ADDRESSES). We describe below the 
process that we undertook for taking into consideration each category 
of impacts and our analyses of the relevant impacts.

[[Page 49962]]

Consideration of Economic Impacts

    Section 4(b)(2) of the Act and its implementing regulations require 
that we consider the economic impact that may result from a designation 
of critical habitat. To assess the probable economic impacts of a 
designation, we must first evaluate specific land uses or activities 
and projects that may occur in the area of the critical habitat. We 
then must evaluate the impacts that a specific critical habitat 
designation may have on restricting or modifying specific land uses or 
activities for the benefit of the species and its habitat within the 
areas proposed. We then identify which conservation efforts may be the 
result of the species being listed under the Act versus those 
attributed solely to the designation of critical habitat for this 
particular species. The probable economic impact of a proposed critical 
habitat designation is analyzed by comparing scenarios both ``with 
critical habitat'' and ``without critical habitat.''
    The ``without critical habitat'' scenario represents the baseline 
for the analysis, which includes the existing regulatory and socio-
economic burden imposed on landowners, managers, or other resource 
users potentially affected by the designation of critical habitat 
(e.g., under the Federal listing as well as other Federal, State, and 
local regulations). Therefore, the baseline represents the costs of all 
efforts attributable to the listing of the species under the Act (i.e., 
conservation of the species and its habitat incurred regardless of 
whether critical habitat is designated). The ``with critical habitat'' 
scenario describes the incremental impacts associated specifically with 
the designation of critical habitat for the species. The incremental 
conservation efforts and associated impacts would not be expected 
without the designation of critical habitat for the species. In other 
words, the incremental costs are those attributable solely to the 
designation of critical habitat, above and beyond the baseline costs. 
These are the costs we use when evaluating the benefits of inclusion 
and exclusion of particular areas from the final designation of 
critical habitat should we choose to conduct a discretionary 4(b)(2) 
exclusion analysis.
    For this particular designation, we developed an incremental 
effects memorandum (IEM) considering the probable incremental economic 
impacts that may result from this proposed designation of critical 
habitat. The information contained in our IEM was then used to develop 
a screening analysis of the probable effects of the designation of 
critical habitat for the Miami tiger beetle (IEc 2021, entire). We 
began by conducting a screening analysis of the proposed designation of 
critical habitat in order to focus our analysis on the key factors that 
are likely to result in incremental economic impacts. The purpose of 
the screening analysis is to filter out the geographic areas in which 
the critical habitat designation is unlikely to result in probable 
incremental economic impacts. In particular, the screening analysis 
considers baseline costs (i.e., absent critical habitat designation) 
and includes any probable incremental economic impacts where land and 
water use may already be subject to conservation plans, land management 
plans, best management practices, or regulations that protect the 
habitat area as a result of the Federal listing status of the species.
    If the proposed critical habitat designation contains any 
unoccupied units, the screening analysis filters out particular areas 
of critical habitat that are already subject to such protections and 
are, therefore, unlikely to incur incremental economic impacts. 
Ultimately, the screening analysis allows us to focus our analysis on 
evaluating the specific areas or sectors that may incur probable 
incremental economic impacts as a result of the designation. If the 
proposed critical habitat designation contains any unoccupied units, 
the screening analysis assesses whether units are unoccupied because 
they require additional management or conservation efforts that may 
incur incremental economic impacts. This screening analysis combined 
with the information contained in our IEM constitute what we consider 
to be our draft economic analysis of the proposed critical habitat 
designation for the Miami tiger beetle and is summarized in the 
narrative below.
    Executive Orders (E.O.) 12866 and 13563 direct Federal agencies to 
assess the costs and benefits of available regulatory alternatives in 
quantitative (to the extent feasible) and qualitative terms. Consistent 
with the E.O. regulatory analysis requirements, our effects analysis 
under the Act may take into consideration impacts to both directly and 
indirectly affected entities, where practicable and reasonable. If 
sufficient data are available, we assess to the extent practicable the 
probable impacts to both directly and indirectly affected entities. As 
part of our screening analysis, we considered the types of economic 
activities that are likely to occur within the areas likely affected by 
the critical habitat designation.
    In our evaluation of the probable incremental economic impacts that 
may result from the proposed designation of critical habitat for the 
Miami tiger beetle, first we identified, in the IEM dated April 28, 
2021, probable incremental economic impacts associated with the 
following categories of activities: (1) Federal lands management (U.S. 
Coast Guard, Corps, FBP, and NOAA); (2) roadway and bridge 
construction; (3) agriculture; (4) dredging; (5) storage and 
distribution of chemical pollutants; (6) commercial or residential 
development; and (7) recreation (including construction of recreation 
infrastructure). We considered each industry or category individually. 
Additionally, we considered whether their activities have any Federal 
involvement. Critical habitat designation generally will not affect 
activities that do not have any Federal involvement; under the Act, 
designation of critical habitat only affects activities conducted, 
funded, permitted, or authorized by Federal agencies. In areas where 
the Miami tiger beetle is present, Federal agencies already are 
required to consult with the Service under section 7 of the Act on 
activities they fund, permit, or implement that may affect the species. 
If we finalize this proposed critical habitat designation, our 
consultation would include an evaluation of measures to avoid the 
destruction or adverse modification of critical habitat.
    In our IEM, we attempted to clarify the distinction between the 
effects that will result from the species being listed and those 
attributable to the critical habitat designation (i.e., difference 
between the jeopardy and adverse modification standards) for the Miami 
tiger beetle's critical habitat. Because the designation of critical 
habitat for the Miami tiger beetle is being proposed several years 
following the listing of the species, data, such as from consultation 
history, is available to help us discern which conservation efforts are 
attributable to the species being listed and those which will result 
solely from the designation of critical habitat. The following specific 
circumstances help to inform our evaluation: (1) The essential physical 
or biological features identified for critical habitat are the same 
features essential for the life requisites of the species and (2) any 
actions that would result in sufficient harm or harassment to 
constitute jeopardy to the Miami tiger beetle would also likely 
adversely affect the essential physical or biological features of 
critical habitat. The IEM outlines our rationale concerning this 
limited distinction between protections

[[Page 49963]]

or economic impacts associated with listing and incremental impacts of 
the designation of critical habitat for this species. This evaluation 
of the incremental effects has been used as the basis to evaluate the 
probable incremental economic impacts of this proposed designation of 
critical habitat.
    The proposed critical habitat designation for the Miami tiger 
beetle totals approximately 1,977 ac (800 ha) in 16 units in Miami-Dade 
County, Florida. Two of the 16 units are currently occupied by the 
Miami tiger beetle; the remaining 14 units are within the beetle's 
historical range but were not occupied at the time the species was 
listed in 2016 and are not known to be currently occupied. As 
previously stated, the 14 unoccupied critical habitat units encompass 
approximately 405 ac (164 ha) or 20 percent of proposed critical 
habitat for the Miami tiger beetle, of which only 17 ac (7 ha) or 4 
percent are not currently designated as critical habitat for other 
federally listed species. Tables 1 through 3, above, set forth specific 
information concerning each unit, including occupancy, land ownership, 
and extent of overlap with existing Federal critical habitat (see 
Proposed Critical Habitat Designation).
    Because the majority (80 percent) of the area designated is 
occupied, most actions that may affect the species or its habitat would 
also affect designated critical habitat, and it is unlikely that any 
additional conservation efforts would be recommended to address the 
adverse modification standard over and above those recommended as 
necessary to avoid jeopardizing the continued existence of the Miami 
tiger beetle. Therefore, only administrative costs are expected in 
approximately 80 percent of the proposed critical habitat designation. 
While the analysis for adverse modification of critical habitat will 
require time and resources by both the Federal action agency and the 
Service, it is believed that, in most circumstances, these costs would 
predominantly be administrative in nature and would not be significant.
    The remaining designated area is unoccupied and mostly (96 percent 
of the unoccupied area) overlaps with existing designated critical 
habitat for other pine rockland habitat species, including Carter's 
small-flowered flax, Florida brickell-bush, Bartram's scrub hairstreak 
butterfly, and the Florida leafwing butterfly. As a result, 
consultations for other listed species and critical habitats are likely 
to have already resulted in protections absent the critical habitat 
designation for the Miami tiger beetle, and recommendations for those 
species are anticipated to be sufficient to protect the Miami tiger 
beetle critical habitat. Further, any consultation requirements for 
listed species and resulting costs would be at least partially split 
among each overlapped species with not one species being the sole 
source of the entire costs. Accordingly, in these unoccupied areas, any 
conservation efforts or associated probable impacts would be considered 
incremental effects attributed to the critical habitat designation.
    The probable incremental economic impacts of the Miami tiger beetle 
critical habitat designation are expected to be limited to additional 
administrative effort as well as minor costs of conservation efforts 
resulting from a small number of future section 7 consultations. This 
is due to two factors: (1) A large portion of proposed critical habitat 
is considered to be occupied by the species (80 percent), and 
incremental economic impacts of critical habitat designation, other 
than administrative costs, are unlikely; and (2) in proposed areas that 
are not occupied by the Miami tiger beetle (20 percent), nearly all is 
designated critical habitat for other pine rockland species and the 
designation is not likely to result in additional or different project 
modifications from those that would already be anticipated absent the 
Miami tiger beetle designation. Because of the relatively small size of 
the critical habitat designation, the volume of lands that are State, 
county, or privately owned, and the substantial amount of lands that 
are already being managed for conservation, the numbers of section 7 
consultations expected annually are modest (approximately 2 formal, 12 
informal, and 14 technical assistance efforts annually across the 
designation).
    Some potential private property value effects are possible due to 
public perception of impacts to private lands. The designation of 
critical habitat may cause some developers or landowners to perceive 
that private lands will be subject to use restrictions or litigation 
from third parties, resulting in costs. However, less than seven 
percent of the proposed critical habitat designation is privately owned 
land, leading to nominal incremental costs arising from changes in 
public perception of lands included in the designation.
    Critical habitat designation for the Miami tiger beetle is unlikely 
to generate costs or benefits exceeding $100 million in a single year. 
Therefore, this rule is unlikely to meet the threshold for an 
economically significant rule, with regard to costs, under E.O. 12866. 
In fact, the total annual incremental costs of critical habitat 
designation for the Miami tiger beetle is anticipated to be less than 
$48,000 per year, and economic benefits are also anticipated to be 
small.
    As we stated earlier, we are soliciting data and comments from the 
public on the draft economic analysis, as well as on all aspects of the 
proposed rule and our amended required determinations. During the 
development of a final designation, we will consider the information 
presented in the draft economic analysis and any additional information 
on economic impacts we receive during the public comment period to 
determine whether any specific areas should be excluded from the final 
critical habitat designation under authority of section 4(b)(2) and our 
implementing regulations at 50 CFR 17.90. If we receive credible 
information regarding the existence of a meaningful economic or other 
relevant impact supporting a benefit of exclusion, we will conduct an 
exclusion analysis for the relevant area or areas. We may also exercise 
the discretion to evaluate any other particular areas for possible 
exclusion. Furthermore, when we conduct an exclusion analysis based on 
impacts identified by experts in, or sources with firsthand knowledge 
about, impacts that are outside the scope of the Service's expertise, 
we will give weight to those impacts consistent with the expert or 
firsthand information unless we have rebutting information. We may 
exclude an area from critical habitat if we determine that the benefits 
of excluding the area outweigh the benefits of including the area, 
provided the exclusion will not result in the extinction of this 
species.

Consideration of National Security Impacts

    Section 4(a)(3)(B)(i) of the Act may not cover all DoD lands or 
areas that pose potential national-security concerns (e.g., a DoD 
installation that is in the process of revising its INRMP for a newly 
listed species or a species previously not covered). If a particular 
area is not covered under section 4(a)(3)(B)(i), then national-security 
or homeland-security concerns are not a factor in the process of 
determining what areas meet the definition of ``critical habitat.'' 
However, the Service must still consider impacts on national security, 
including homeland security, on those lands or areas not covered by 
section 4(a)(3)(B)(i), because section 4(b)(2) requires the Service to 
consider those impacts whenever it designates critical habitat. 
Accordingly, if DoD, Department of Homeland Security (DHS), or another 
Federal agency has

[[Page 49964]]

requested exclusion based on an assertion of national-security or 
homeland security concerns, or we have otherwise identified national 
security or homeland-security impacts from designating particular areas 
as critical habitat, we generally have reason to consider excluding 
those areas.
    However, we cannot automatically exclude requested areas. When DoD, 
DHS, or another Federal agency requests exclusion from critical habitat 
on the basis of national-security or homeland-security impacts, we must 
conduct an exclusion analysis if the Federal requester provides 
credible information, including a reasonably specific justification of 
an incremental impact on national security that would result from the 
designation of that specific area as critical habitat. That 
justification could include demonstration of probable impacts, such as 
impacts to ongoing border-security patrols and surveillance activities, 
or a delay in training or facility construction, as a result of 
compliance with section 7(a)(2) of the Act. If the agency requesting 
the exclusion does not provide us with a reasonably specific 
justification, we will contact the agency to recommend that it provide 
a specific justification or clarification of its concerns relative to 
the probable incremental impact that could result from the designation. 
If we conduct an exclusion analysis because the agency provides a 
reasonably specific justification or because we decide to exercise the 
discretion to conduct an exclusion analysis, we will defer to the 
expert judgment of DoD, DHS, or another Federal agency as to: (1) 
Whether activities on its lands or waters, or its activities on other 
lands or waters, have national-security or homeland-security 
implications; (2) the importance of those implications; and (3) the 
degree to which the cited implications would be adversely affected in 
the absence of an exclusion. In that circumstance, in conducting a 
discretionary section 4(b)(2) exclusion analysis, we will give great 
weight to national-security and homeland-security concerns in analyzing 
the benefits of exclusion.

DHS Land Parcel

    We have determined that some lands within Unit 14 of the proposed 
designation of critical habitat for the Miami tiger beetle are owned, 
managed, or used by the U.S. Coast Guard, which is part of the DHS.
    As discussed in the Richmond Pine Rocklands (Unit 14) description 
above, the U.S. Coast Guard property is separated into two main areas: 
The COMMSTA Miami and the CEU. The COMMSTA houses transmitting and 
receiving antennas. The CEU plans and executes projects at regional 
shore facilities, such as construction and post-disaster assessments.
    The U.S. Coast Guard parcel contains approximately 100 ac (40 ha) 
of standing pine rocklands. The remainder of the site, outside of the 
developed areas, is made up of scraped pine rocklands that are mowed 
three to four times per year for maintenance of a communications 
antenna field. While disturbed, this scraped area maintains sand 
substrate and many native pine rockland species, including documented 
occurrences of the Miami tiger beetle. The U.S. Coast Guard parcel has 
a draft management plan that includes management of pine rockland 
habitats, including vegetation control and prescribed fire and 
protection of lands from further development or degradation. In 
addition, the standing pine rockland area is partially managed through 
an active recovery grant to the Institute for Regional Conservation. 
Under this grant, up to 39 ac (16 ha) of standing pine rocklands will 
undergo invasive vegetation control.
    Based on a review of the specific mission of the U.S. Coast Guard 
facility in conjunction with the measures and efforts set forth in the 
draft management plan to preserve pine rockland habitat and protect 
sensitive and listed species, we have made a preliminary determination 
that it is unlikely that the critical habitat, if finalized as 
proposed, would negatively impact the facility or its operations. As a 
result, we do not anticipate any impact on national security. However, 
if through the public comment period we receive credible information 
regarding impacts on national security or homeland security from 
designating particular areas as critical habitat, then as part of 
developing the final designation of critical habitat, we will conduct a 
discretionary exclusion analysis to determine whether to exclude those 
areas under authority of section 4(b)(2) and our implementing 
regulations at 50 CFR 17.90.

DoD Land Parcel

    As discussed above, we have determined that the Corps, a branch of 
the DoD, retains ownership over a 121-ac (49-ha)-parcel in Unit 14 of 
the proposed designation of critical habitat for the Miami tiger 
beetle. Over 85-ac (34-ha) of this parcel are forested but not managed 
for preservation of natural resources. The Corps does not have any 
specific management plan for the Miami tiger beetle or its habitat 
covering these lands. Activities conducted on this site are unknown, 
but we do not anticipate any impact on national security. However, if 
through the public comment period we receive credible information 
regarding impacts on national security or homeland security from 
designating particular areas as critical habitat, then as part of 
developing the final designation of critical habitat, we will conduct a 
discretionary exclusion analysis to determine whether to exclude those 
areas under authority of section 4(b)(2) and our implementing 
regulations at 50 CFR 17.90.

Consideration of Other Relevant Impacts

    Under section 4(b)(2) of the Act, we consider any other relevant 
impacts, in addition to economic impacts and impacts on national 
security discussed above. Other relevant impacts may include, but are 
not limited to, impacts to Tribes, States, local governments, public 
health and safety, community interests, the environment (such as 
increased risk of wildfire or pest and invasive species management), 
Federal lands, and conservation plans, agreements, or partnerships. To 
identify other relevant impacts that may affect the exclusion analysis, 
we consider a number of factors, including whether there are permitted 
conservation plans covering the species in the area--such as HCPs, safe 
harbor agreements (SHAs), or candidate conservation agreements with 
assurances (CCAAs)--or whether there are non-permitted conservation 
agreements and partnerships that may be impaired by designation of, or 
exclusion from, critical habitat. In addition, we look at whether 
Tribal conservation plans or partnerships, Tribal resources, or 
government-to-government relationships of the United States with Tribal 
entities may be affected by the designation. We also consider any 
State, local, public-health, community-interest, environmental, or 
social impacts that might occur because of the designation.
    When analyzing other relevant impacts of including a particular 
area in a designation of critical habitat, we weigh those impacts 
relative to the conservation value of the particular area. To determine 
the conservation value of designating a particular area, we consider a 
number of factors, including, but not limited to, the additional 
regulatory benefits that the area would receive due to the protection 
from destruction or adverse modification as a result of actions with a 
Federal nexus, the educational benefits of mapping essential habitat 
for recovery of the listed species, and any

[[Page 49965]]

benefits that may result from a designation due to State or Federal 
laws that may apply to critical habitat.
    In the case of Miami tiger beetle, the benefits of critical habitat 
include public awareness of the presence of Miami tiger beetle and the 
importance of habitat protection, and, where a Federal nexus exists, 
increased habitat protection for Miami tiger beetle due to protection 
from destruction or adverse modification of critical habitat. Continued 
implementation of an ongoing management plan that provides conservation 
equal to or more than the protections that result from a critical 
habitat designation would reduce those benefits of including that 
specific area in the critical habitat designation.
    We evaluate the existence of a conservation plan when considering 
the benefits of inclusion. We consider a variety of factors, including, 
but not limited to, whether the plan is finalized; how it provides for 
the conservation of the essential physical or biological features; 
whether there is a reasonable expectation that the conservation 
management strategies and actions contained in a management plan will 
be implemented into the future; whether the conservation strategies in 
the plan are likely to be effective; and whether the plan contains a 
monitoring program or adaptive management to ensure that the 
conservation measures are effective and can be adapted in the future in 
response to new information.
    After identifying the benefits of inclusion and the benefits of 
exclusion, we carefully weigh the two sides to evaluate whether the 
benefits of exclusion outweigh those of inclusion. If our analysis 
indicates that the benefits of exclusion outweigh the benefits of 
inclusion, we then determine whether exclusion would result in 
extinction of the species. If exclusion of an area from critical 
habitat will result in extinction, we will not exclude it from the 
designation.

Private or Other Non-Federal Conservation Plans or Agreements and 
Partnerships, in General

    HCPs for incidental take permits under section 10(a)(1)(B) of the 
Act provide for partnerships with non-Federal entities to minimize and 
mitigate impacts to listed species and their habitat. In some cases, 
HCP permittees agree to do more for the conservation of the species and 
their habitats on private lands than designation of critical habitat 
would provide alone. We place great value on the partnerships that are 
developed during the preparation and implementation of HCPs.
    CCAAs and SHAs are voluntary agreements designed to conserve 
candidate and listed species, respectively, on non-Federal lands. In 
exchange for actions that contribute to the conservation of species on 
non-Federal lands, participating property owners are covered by an 
``enhancement of survival'' permit under section 10(a)(1)(A) of the 
Act, which authorizes incidental take of the covered species that may 
result from implementation of conservation actions, specific land uses, 
and, in the case of SHAs, the option to return to a baseline condition 
under the agreements. The Service also provides enrollees assurances 
that we will not impose further land-, water-, or resource-use 
restrictions, or require additional commitments of land, water, or 
finances, beyond those agreed to in the agreements.
    When we undertake a discretionary section 4(b)(2) exclusion 
analysis based on permitted conservation plans such as CCAAs, SHAs, and 
HCPs, we consider the following three factors:
    (i) Whether the permittee is properly implementing the conservation 
plan or agreement;
    (ii) Whether the species for which critical habitat is being 
designated is a covered species in the conservation plan or agreement; 
and
    (iii) Whether the conservation plan or agreement specifically 
addresses the habitat of the species for which critical habitat is 
being designated and meets the conservation needs of the species in the 
planning area.
    The proposed critical habitat designation includes areas that are 
covered by the following permitted plan providing for the conservation 
of Miami tiger beetle: Coral Reef Commons Habitat Conservation Plan.

Coral Reef Commons Habitat Conservation Plan

    In preparing this proposal, we have determined that lands 
associated with the Coral Reef Commons HCP within the Richmond Pine 
Rocklands (Unit 14) are included within the boundaries of the proposed 
critical habitat.
    As discussed in the Richmond Pine Rocklands (Unit 14) description 
above, Coral Reef Commons is a mixed-use community, which consists of 
900 apartments, retail stores, restaurants, and parking. In 2017, an 
HCP and associated permit under section 10 of the Act was developed and 
issued for the Coral Reef Commons development. As part of the HCP and 
permit, an approximately 51-ac (21-ha) onsite preserve (same as the 
area for proposed critical habitat designation) was established under a 
conservation encumbrance that will be managed in perpetuity for pine 
rockland habitat and sensitive and listed species, including the Miami 
tiger beetle. In addition, an additional approximately 51-ac (21-ha) of 
the CSTARS site (discussed above) is an offsite mitigation area for 
Coral Reef Commons. Both the onsite preserve and the offsite mitigation 
area are being managed to maintain healthy pine rockland habitat 
through the use of invasive, exotic plant management, mechanical 
treatment, and prescribed fire, addressing both the habitat and 
conservation needs of the species. Since initiating the Coral Reef 
Commons HCP, pine rockland restoration efforts have been conducted 
within all of the management units in both the onsite preserve and the 
offsite mitigation area. A second round of prescribed fire began in 
February 2021. Currently, the onsite preserve meets or exceeds the 
success criteria described for proper implementation of the HCP.
    Critical habitat within Unit 14 that is associated with the Coral 
Reef Commons HCP is limited to the onsite preserve and offsite 
mitigation area. Based on our review of the HCP and proposed critical 
habitat for the Miami tiger beetle, we do not anticipate requesting any 
additional conservation measures for the species beyond those that are 
currently in place. The Coral Reef Commons HCP covers the Miami tiger 
beetle; addresses the specific habitat of the species and meets the 
conservation needs of the species; and is currently being implemented 
properly. Therefore, at this time, we are considering excluding those 
specific lands associated with the Coral Reef Commons HCP that are in 
the preserve and offsite mitigation area from the final designation of 
critical habitat for the Miami tiger beetle. However, we will more 
thoroughly review the HCP, its implementation of the conservation 
measures for the Miami tiger beetle and its habitat therein, and public 
comment on this issue prior to finalizing critical habitat, and if 
appropriate, exclude from critical habitat for the Miami tiger beetle 
those lands associated with the Coral Reef Commons HCP that are in the 
preserve and offsite mitigation area.
    We have further determined that there are no additional HCPs or 
other management plans for the Miami tiger beetle within the proposed 
critical habitat designation.

Tribal Lands

    Several Executive Orders, Secretarial Orders, and policies concern 
working with Tribes. These guidance documents generally confirm our 
trust responsibilities to Tribes, recognize that

[[Page 49966]]

Tribes have sovereign authority to control Tribal lands, emphasize the 
importance of developing partnerships with Tribal governments, and 
direct the Service to consult with Tribes on a government-to-government 
basis. There are no Tribal lands within the designated critical habitat 
for Miami tiger beetle.
    During the development of a final designation, we will consider any 
additional information received through the public comment period 
regarding other relevant impacts to determine whether any specific 
areas should be excluded from the final critical habitat designation 
under authority of section 4(b)(2) and our implementing regulations at 
50 CFR 17.90.

Required Determinations

Clarity of the Rule

    We are required by Executive Orders 12866 and 12988 and by the 
Presidential Memorandum of June 1, 1998, to write all rules in plain 
language. This means that each rule we publish must:
    (1) Be logically organized;
    (2) Use the active voice to address readers directly;
    (3) Use clear language rather than jargon;
    (4) Be divided into short sections and sentences; and
    (5) Use lists and tables wherever possible.
    If you feel that we have not met these requirements, send us 
comments by one of the methods listed in ADDRESSES. To better help us 
revise the rule, your comments should be as specific as possible. For 
example, you should tell us the numbers of the sections or paragraphs 
that are unclearly written, which sections or sentences are too long, 
the sections where you feel lists or tables would be useful, etc.

Regulatory Planning and Review (Executive Orders 12866 and 13563)

    Executive Order 12866 provides that the Office of Information and 
Regulatory Affairs (OIRA) in the Office of Management and Budget will 
review all significant rules. OIRA has determined that this rule is not 
significant.
    Executive Order 13563 reaffirms the principles of E.O. 12866 while 
calling for improvements in the nation's regulatory system to promote 
predictability, to reduce uncertainty, and to use the best, most 
innovative, and least burdensome tools for achieving regulatory ends. 
The executive order directs agencies to consider regulatory approaches 
that reduce burdens and maintain flexibility and freedom of choice for 
the public where these approaches are relevant, feasible, and 
consistent with regulatory objectives. E.O. 13563 emphasizes further 
that regulations must be based on the best available science and that 
the rulemaking process must allow for public participation and an open 
exchange of ideas. We have developed this proposed rule in a manner 
consistent with these requirements.

Regulatory Flexibility Act (5 U.S.C. 601 et seq.)

    Under the Regulatory Flexibility Act (RFA; 5 U.S.C. 601 et seq.), 
as amended by the Small Business Regulatory Enforcement Fairness Act of 
1996 (SBREFA; 5 U.S.C. 801 et seq.), 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 effects 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 the 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 
certification statement of the factual basis for certifying that the 
rule will not have a significant economic impact on a substantial 
number of small entities.
    According to the Small Business Administration, 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; and small businesses (13 CFR 121.201). 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 considered the 
types of activities that might trigger regulatory impacts under this 
designation as well as 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.
    Under the RFA, as amended, and as understood in light of recent 
court decisions, Federal agencies are required to evaluate the 
potential incremental impacts of rulemaking only on those entities 
directly regulated by the rulemaking itself; in other words, the RFA 
does not require agencies to evaluate the potential impacts to 
indirectly regulated entities. The regulatory mechanism through which 
critical habitat protections are realized is section 7 of the Act, 
which requires Federal agencies, in consultation with the Service, to 
ensure that any action authorized, funded, or carried out by the agency 
is not likely to destroy or adversely modify critical habitat. 
Therefore, under section 7, only Federal action agencies are directly 
subject to the specific regulatory requirement (avoiding destruction 
and adverse modification) imposed by critical habitat designation. 
Consequently, it is our position that only Federal action agencies 
would be directly regulated if we adopt the proposed critical habitat 
designation. The RFA does not require evaluation of the potential 
impacts to entities not directly regulated. Moreover, Federal agencies 
are not small entities. Therefore, because no small entities would be 
directly regulated by this rulemaking, the Service certifies that, if 
made final as proposed, the proposed critical habitat designation will 
not have a significant economic impact on a substantial number of small 
entities.
    In summary, we have considered whether the proposed designation 
would result in a significant economic impact on a substantial number 
of small entities. For the above reasons and based on currently 
available information, we certify that, if made final, the proposed 
critical habitat designation would not have a significant economic 
impact on a substantial number of small business entities. Therefore, 
an initial regulatory flexibility analysis is not required.

Energy Supply, Distribution, or Use--Executive Order 13211

    Executive Order 13211 (Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use) requires 
agencies to prepare Statements of Energy Effects when undertaking 
certain actions. In our economic analysis, we did not find that the 
designation of this proposed critical habitat will significantly affect 
energy supplies, distribution, or use. We do not foresee any energy 
development projects, supply distribution or use that may affect the 
proposed critical habitat units for the Miami tiger beetle. Further,

[[Page 49967]]

in our evaluation of potential economic impacts, we did not find that 
this proposed critical habitat designation would 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 finding:
    (1) This proposed rule would 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, or 
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; Aid to Families 
with Dependent Children 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 that receive 
Federal funding, assistance, or permits, or that 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 onto State governments.
    (2) We do not believe that this rule will significantly or uniquely 
affect small governments because the government lands being proposed 
for critical habitat designation are owned by the Federal Government, 
including the U.S. Coast Guard (DHS), U.S. Army Corps of Engineers 
(DoD), NOAA, and FBP; or are State or local governments such as the 
State of Florida, and Miami-Dade County. None of these government 
entities fit the definition of ``small governmental jurisdiction.'' 
Therefore, a Small Government Agency Plan is not required.

Takings--Executive Order 12630

    In accordance with E.O. 12630 (Government Actions and Interference 
with Constitutionally Protected Private Property Rights), we have 
analyzed the potential takings implications of designating critical 
habitat for the Miami tiger beetle in a takings implications 
assessment. The Act does not authorize the Service to regulate private 
actions on private lands or confiscate private property as a result of 
critical habitat designation. Designation of critical habitat does not 
affect land ownership, or establish any closures or restrictions on use 
of or access to the designated areas. Furthermore, the designation of 
critical habitat does not affect landowner actions that do not require 
Federal funding or permits, nor does it preclude development of habitat 
conservation programs or issuance of incidental take permits to permit 
actions that do require Federal funding or permits to go forward. 
However, Federal agencies are prohibited from carrying out, funding, or 
authorizing actions that would destroy or adversely modify critical 
habitat. A takings implications assessment has been completed for the 
proposed designation of critical habitat for the Miami tiger beetle and 
concludes that, if adopted, this designation of critical habitat does 
not pose significant takings implications for lands within or affected 
by the designation.

Federalism--Executive Order 13132

    In accordance with E.O. 13132 (Federalism), this proposed rule does 
not have significant Federalism effects. A federalism summary impact 
statement is not required. In keeping with Department of the Interior 
and Department of Commerce policy, we requested information from, and 
coordinated development of this proposed critical habitat designation 
with, appropriate State resource agencies. From a federalism 
perspective, the designation of critical habitat directly affects only 
the responsibilities of Federal agencies. The Act imposes no other 
duties with respect to critical habitat, either for States and local 
governments, or for anyone else. As a result, the proposed rule does 
not have substantial direct effects either on the States, or on the 
relationship between the national government and the States, or on the 
distribution of powers and responsibilities among the various levels of 
government. The proposed designation may have some benefit to these 
governments because the areas that contain the features essential to 
the conservation of the species are more clearly defined, and the 
physical or biological features of the habitat necessary for the 
conservation of the species are specifically identified. This 
information does not alter where and what federally sponsored 
activities may occur. However, it may assist State and local 
governments in long-range planning because they no longer have to wait 
for case-by-case section 7 consultations to occur.
    Where State and local governments require approval or authorization 
from a Federal agency for actions that may affect critical habitat, 
consultation under section 7(a)(2) of the Act would be required. While 
non-Federal entities that receive Federal funding, assistance, or 
permits, or that 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.

Civil Justice Reform--Executive Order 12988

    In accordance with Executive Order 12988 (Civil Justice Reform), 
the Office of the Solicitor has determined that the rule would not 
unduly burden the judicial system and that it meets the requirements of 
sections 3(a) and 3(b)(2) of the Order. We have proposed

[[Page 49968]]

designating critical habitat in accordance with the provisions of the 
Act. To assist the public in understanding the habitat needs of the 
species, this proposed rule identifies the physical or biological 
features essential to the conservation of the species. The proposed 
areas of critical habitat are presented on maps, and the proposed rule 
provides several options for the interested public to obtain more 
detailed location information, if desired.

Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)

    This rule does not contain information collection requirements, and 
a submission to the Office of Management and Budget (OMB) under the 
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) is not 
required. We may not conduct or sponsor and you are not required to 
respond to a collection of information unless it displays a currently 
valid OMB control number.

National Environmental Policy Act (42 U.S.C. 4321 et seq.)

    It is our position that, outside the jurisdiction of the U.S. Court 
of Appeals for the Tenth Circuit, we do not need to prepare 
environmental analyses pursuant to the National Environmental Policy 
Act (NEPA; 42 U.S.C. 4321 et seq.) in connection with regulations 
adopted pursuant to section 4(a) of the Act. We published a notice 
outlining our reasons for this determination in the Federal Register on 
October 25, 1983 (48 FR 49244). This position was upheld by the U.S. 
Court of Appeals for the Ninth Circuit (Douglas County v. Babbitt, 48 
F.3d 1495 (9th Cir. 1995), cert. denied 516 U.S. 1042 (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 (Consultation and 
Coordination with Indian Tribal Governments), and the Department of the 
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. In accordance with 
Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights, 
Federal-Tribal Trust Responsibilities, and the Endangered Species Act), 
we readily acknowledge our responsibilities to work directly with 
Tribes in developing programs for healthy ecosystems, to acknowledge 
that Tribal lands are not subject to the same controls as Federal 
public lands, to remain sensitive to Indian culture, and to make 
information available to Tribes.
    We determined that there are no Tribal lands that were occupied by 
the Miami tiger beetle at the time of listing that contain the features 
essential for conservation of the species, and no Tribal lands 
unoccupied by the Miami tiger beetle that are essential for the 
conservation of the species. Therefore, we are not proposing to 
designate critical habitat for the Miami tiger beetle on Tribal lands. 
As a result, there are no Tribal lands affected by the proposed 
designation of critical habitat for this species.

Miami Tiger Beetle (Cicindelidia floridana)

    (1) Critical habitat units are depicted for Miami-Dade County, 
Florida, on the maps in this entry.
    (2) Within these areas, the physical or biological features 
essential to the conservation of the Miami tiger beetle consist of one 
or more of the following components:
    (i) South Florida pine rockland habitat of at least 2.5 ac (1 ha) 
in size that is maintained by natural or prescribed fire or other 
disturbance regimes; and
    (ii) Open sandy areas within or directly adjacent to the south 
Florida pine rockland habitat with little to no vegetation that allows 
for or facilitates normal behavior and growth such as thermoregulation, 
foraging, egg-laying, larval development, and habitat connectivity, 
which promotes the

[[Page 49969]]

overall distribution and expansion of the species.
    (3) Critical habitat does not include manmade structures (such as 
buildings, aqueducts, runways, roads, and other paved areas) and the 
land on which they are located existing within the legal boundaries on 
the effective date of this rule.
    (4) Critical habitat map units. Data layers defining map units were 
created using Esri ArcGIS mapping software. The projection used was 
Albers Conical Equal Area (Florida Geographic Data Library), NAD 1983 
HARN. The maps in this entry, as modified by any accompanying 
regulatory text, establish the boundaries of the critical habitat 
designation. The spatial data used to create the critical habitat unit 
maps are available to the public at the Service's internet site, http://www.fws.gov/verobeach/, or http://www.regulations.gov at Docket No. 
FWS-R4-ES-2021-0053.
