AGENCY:

Fish and Wildlife Service, Interior.

ACTION:

Notice.

SUMMARY:

The U.S. Fish and Wildlife Service (Service) is initiating 5-year reviews of the Carolina northern flying squirrel (Glaucomys sabrinus coloratus), Cahow (Pterodroma cahow), boulder darter (Etheostoma wapiti), relict darter (Etheostoma chienense), Cumberland pigtoe (Pleurobema gibberum), rough pigtoe (Pleurobema plenum), orangefoot pimpleback (pearlymussel) (Plethobasus cooperianus), tan riffleshell (Epioblasma florentina walkeri), white wartyback (pearlymussel) (Plethobasus cicatricosus), noonday snail (Mesodon clarki nantahala), Nashville crayfish (Orconectes shoupi), Kentucky cave shrimp (Palaemonias ganteri), Cumberland sandwort (Arenaria cumberlandensis), Tennessee purple coneflower (Echinacea tennesseensis), large-flowered skullcap (Scutellaria Start Printed Page 54058montana), and rock gnome lichen (Gymnoderma lineare) under section 4(c)(2) of the Endangered Species Act of 1973, as amended (Act). The purpose of reviews conducted under this section of the Act is to ensure that the classification of species as threatened or endangered on the List of Endangered and Threatened Wildlife and Plants (50 CFR 17.11 and 17.12) is accurate. A 5-year review is an assessment of the best scientific and commercial data available at the time of the review.

SUPPLEMENTARY INFORMATION:

Under the Act (16 U.S.C. 1533 et seq.), the Service maintains a list of endangered and threatened wildlife and plant species at 50 CFR 17.11 (for animals) and 17.12 (for plants) (collectively referred to as the List). Section 4(c)(2)(A) of the Act requires that we conduct a review of listed species at least once every 5 years. Then, on the basis of such reviews, under section 4(c)(2)(B), we determine whether or not any species should be removed from the List (delisted), or reclassified from endangered to threatened or from threatened to endangered. Delisting a species must be supported by the best scientific and commercial data available and only considered if such data substantiate that the species is neither endangered nor threatened for one or more of the following reasons: (1) The species is considered extinct; (2) the species is considered to be recovered; and/or (3) the original data available when the species was listed, or the interpretation of such data, were in error. Any change in Federal classification would require a separate rulemaking process. Amendments to the List through final rules are published in the Federal Register.

The regulations at 50 CFR 424.21 require that we publish a notice in the Federal Register announcing those species currently under active review. This notice announces our active review of the following species listed as endangered: Carolina northern flying squirrel (mammal), Cahow (bird), boulder darter (fish), relict darter (fish), Cumberland pigtoe (mussel), rough pigtoe (mussel), orangefoot pimpleback (mussel), tan riffleshell (mussel), white wartyback (mussel), Nashville crayfish (crayfish), Kentucky cave shrimp (shrimp), Cumberland sandwort (plant), Tennessee purple coneflower (plant), and rock gnome lichen (lichen). This notice also covers two species that are listed as threatened: noonday snail (snail) and large-flowered skullcap (plant). The List is also available on our Internet site at http://endangered.fws.gov/​wildlife.html#Species.

What information is considered in the review?

A 5-year review considers all new information available at the time of the review. A 5-year review will consider the best scientific and commercial data that have become available since the current listing determination or most recent status review of each species, such as:

A. Species biology, including but not limited to population trends, distribution, abundance, demographics, and genetics;

B. Habitat conditions, including but not limited to amount, distribution, and suitability;

C. Conservation measures that have been implemented to benefit the species;

D. Threat status and trends (see five factors under heading “How do we determine whether a species is endangered or threatened?”); and

E. Other new information, data, or corrections, including but not limited to taxonomic or nomenclatural changes, identification of erroneous information contained in the List, and improved analytical methods.

Specific information Requested for the Boulder Darter, Cumberland Pigtoe, Orangefoot Pimpleback, White Wartyback, and Rock Gnome Lichen

We are especially interested in obtaining information about the present condition of the species' habitats, recovery of degraded habitats, threats to extant populations, discovery of new populations, or rediscovery of populations thought to be extirpated. We are also interested in information about ongoing or successfully completed recovery activities. We specifically request information regarding the current distribution of the Start Printed Page 54059species throughout their ranges and the status of extant populations.

Definitions Related to This Notice

The following definitions are provided to assist those persons who contemplate submitting information regarding the species being reviewed:

A. Species includes any species or subspecies of fish, wildlife, or plant, and any distinct population segment of any species of vertebrate which interbreeds when mature.

B. Endangered means any species that is in danger of extinction throughout all or a significant portion of its range.

C. Threatened means any species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.

How do we determine whether a species is endangered or threatened?

Section 4(a)(1) of the Act establishes that we determine whether a species is endangered or threatened based on one or more of the following five factors:

A. The present or threatened destruction, modification, or curtailment of its habitat or range;

B. Over-utilization for commercial, recreational, scientific, or educational purposes;

C. Disease or predation;

D. The inadequacy of existing regulatory mechanisms; or

E. Other natural or manmade factors affecting its continued existence.

Section 4(a)(1) of the Act requires that our determination be made on the basis of the best scientific and commercial data available.

What could happen as a result of this review?

If we find that there is new information concerning any of these 16 species indicating that a change in classification may be warranted, we may propose a new rule that could do one of the following: (a) Reclassify the species from endangered to threatened (downlist); (b) reclassify the species from threatened to endangered (uplist); or (c) delist the species. If we determine that a change in classification is not warranted, then these species will remain on the List under their current status.

Public Solicitation of New Information

We request any new information concerning the status of any of these 16 species. See “What information is considered in the review?” heading for specific criteria. Information submitted should be supported by documentation such as maps, bibliographic references, methods used to gather and analyze the data, and/or copies of any pertinent publications, reports, or letters by knowledgeable sources. Our practice is to make comments, including names and home addresses of respondents, available for public review during regular business hours. Individual respondents may request that we withhold their names and home addresses, etc., but if you wish us to withhold this information, you must state this prominently at the beginning of your comments. In addition, you must present rationale for withholding this information. This rationale must demonstrate that disclosure would constitute a clearly unwarranted invasion of privacy. Unsupported assertions will not meet this burden. In absence of exceptional, undocumented circumstances, this information will be released. We will make all submissions from organizations or businesses, and from individuals identifying themselves as representatives or officials of organizations or businesses, available for public inspection in their entirety.
