Partial 90-Day Finding on a Petition To List 475 Species in the Southwestern United States as Threatened or Endangered With Critical Habitat

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on 270 species from a petition to list 475 species in the southwestern United States as threatened or endangered under the Endangered Species Act of 1973, as amended (Act). We find that for these 270 species the petition does not present substantial scientific or commercial information indicating that listing these species may be warranted. Therefore, for these 270 species, we will not initiate a further status review in response to this petition. We ask the public to submit to us any new information that becomes available concerning the status of these 270 species or threats to them or their habitat at any time. This information will help us monitor and encourage the conservation of these species. An additional 5 species of the 475 included in the petition do not fall within the scope of the petition or are not a listable entity and, therefore, were not considered in this finding (see Petition).
