Endangered and Threatened Wildlife and Plants; 12-Month Not-Warranted Finding for the Rio Grande Cutthroat Trout

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.
