Rio Grande Cutthroat Preservation

296In a collaboration between the Department of Game and Fish, Colorado Division of Parks and Wildlife, Vermejo Park Ranch and the U.S. Fish and Wildlife Service, the Rio Grande cutthroat trout will have protected habitat long into the future. A Candidate Conservation Agreement with Assurances (CCAA) for Vermejo Park Ranch, recently approved by the U.S. Fish and Wildlife Service, will help conserve and restore the New Mexico State Fish and other native fish in the Costilla watershed.

At Vermejo Park Ranch, non-native trout were removed and Rio Grande cutthroat were stocked. Non-native trout will continue to be removed from the waterways until the restoration is complete. Because of the CCAA, the Costilla basin is set to provide important habitat for New Mexico’s native trout for many years to come.

Although not listed as endangered, the Rio Grande cutthroat trout is a candidate species for federal protection under the Endangered Species Act. The Department is working hard to keep the fish off the endangered species list by increasing the subspecies’ range and the number of populations through habitat restoration and stocking. Currently, Rio Grande cutthroats are found in about 10 percent of the species’ historic habitat, which encompassed the Rio Grande, Pecos River and Canadian River basins in New Mexico and Colorado. The species faces many challenges, including non-native fish, fragmented populations, drought and poor habitat.
