Department of the Interior February 23, 2011 – Federal Register Recent Federal Regulation Documents

We, the U.S. Fish and Wildlife Service, announce a 12-month finding on a petition to list Thorne's hairstreak butterfly (Callophrys [Mitoura] gryneus thornei) as endangered under the Endangered Species Act of 1973, as amended (Act). After review of all available scientific and commercial information, we find that listing Thorne's hairstreak butterfly is not warranted at this time. However, we ask the public to submit to us any new information that becomes available concerning the threats to Thorne's hairstreak butterfly or its habitat at any time.

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list Astragalus hamiltonii (Hamilton milkvetch), Penstemon flowersii (Flowers penstemon), Eriogonum soredium (Frisco buckwheat), Lepidium ostleri (Ostler's peppergrass), and Trifolium friscanum (Frisco clover) as threatened or endangered under the Endangered Species Act of 1973 (ESA), as amended. After review of all available scientific and commercial information, we find that listing A. hamiltonii and P. flowersii is not warranted at this time. However, we ask the public to submit to us new information that becomes available concerning the threats to A. hamiltonii and P. flowersii or their habitat at any time. We find that listing E. soredium, L. ostleri, and T. friscanum as threatened or endangered is warranted. However, currently listing E. soredium, L. ostleri, and T. friscanum is precluded by higher priority actions to amend the Federal Lists of Endangered and Threatened Wildlife and Plants. Upon publication of this 12-month petition finding, we will add E. soredium, L. ostleri, and T. friscanum to our candidate species list. We will develop proposed rules to list E. soredium, L. ostleri, and T. friscanum as our priorities allow. We will make determinations on critical habitat during development of the proposed listing rules. In the interim period, we will address the status of the candidate taxa through our annual Candidate Notice of Review.
