Endangered and Threatened Wildlife and Plants; 12-Month Finding on a Petition To List a Distinct Population Segment of the Roundtail Chub (Gila robusta) in the Lower Colorado River Basin
We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list a distinct population segment (DPS) of the roundtail chub (Gila robusta) in the lower Colorado River basin as endangered or threatened under the Endangered Species Act of 1973, as amended (Act). The petition also asked the Service to designate critical habitat. After review of all available scientific and commercial information, we find that the petitioned listing action is warranted, but precluded by higher priority actions to amend the Lists of Endangered and Threatened Wildlife and Plants. Upon publication of this 12-month petition finding, this species will be added to our candidate species list. We will develop a proposed rule to list this population segment of the roundtail chub pursuant to our Listing Priority System. Any determinations on critical habitat will be made at that time.
