The Preble’s mouse has been designated by the U.S. Fish and Wildlife Service as a threatened species under the Endangered Species Act. This designation prohibits the unlawful disturbance / destruction of the Preble’s mouse or its habitat.
In July 2008, protections for Preble’s mouse populations were removed in Wyoming, but the mouse remains protected as a threatened species in Colorado.
Any potential habitat within Castle Rock and Douglas County may be subject to the requirements of the Endangered Species Act. The Fish and Wildlife Service recommends sites below 7,600 feet within 300 feet of FEMA-designated 100-year floodplains be surveyed for the Preble’s mouse.
