Fish and Wildlife Service May 31, 2011 – Federal Register Recent Federal Regulation Documents

We, the Fish and Wildlife Service (Service), announce a 12- month finding on a petition to list the Puerto Rican harlequin butterfly (Atlantea tulita) as endangered and to designate critical habitat under the Endangered Species Act of 1973, as amended. After reviewing all available scientific and commercial information, we find that the listing of the Puerto Rican harlequin butterfly is warranted. Currently, however, listing the Puerto Rican harlequin butterfly is precluded by higher priority actions to amend the Lists of Endangered and Threatened Wildlife and Plants. Upon publication of this 12-month petition finding, we will add the Puerto Rican harlequin butterfly to our candidate species list. If an emergency situation develops with this species that warrants an emergency listing, we will act immediately to provide additional protection. We will develop a proposed rule to list the Puerto Rican harlequin butterfly as our priorities allow. We will make any determination on critical habitat during development of the proposed listing rule. During any interim period, we will address the status of the candidate taxon through our annual Candidate Notice of Review (CNOR).
