Fish and Wildlife Service December 10, 2024 – Federal Register Recent Federal Regulation Documents

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis) as an endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). Rio Grande cutthroat trout, a subspecies of cutthroat trout (Oncorhynchus clarkii), inhabit high-elevation streams in New Mexico and southern Colorado. After a thorough review of the best available scientific and commercial information, we find that listing the Rio Grande cutthroat trout as an endangered or threatened species is not warranted at this time. However, we ask the public to submit to us at any time any new information relevant to the status of the Rio Grande cutthroat trout or its habitat.

We, the U.S. Fish and Wildlife Service (Service), list the Pe[ntilde]asco least chipmunk (Neotamias minimus atristriatus), a mammal from New Mexico, as an endangered species under the Endangered Species Act of 1973 (Act), as amended. We also designate critical habitat. In total, approximately 1,774 hectares (4,386 acres) in Lincoln County, New Mexico, fall within the boundaries of the critical habitat designation. This rule extends the protections of the Act to this species and its designated critical habitat.
