ENDANGERED SPECIES ACT PROFILE

PROTECTION STATUS: Threatened in Colorado; unprotected in Wyoming

YEAR PLACED ON LIST: 1998

CRITICAL HABITAT: 31,222 acres along 359 miles of river in Colorado and Wyoming designated in 2003

RECOVERY PLAN: Preliminary draft only revised in 2003

RANGE: Along portions of the North Platte, South Platte, and Arkansas River basins in Colorado and Wyoming

THREATS: Habitat loss and degradation due to agricultural, residential, commercial, and industrial development, with urban development as the primary cause in Colorado and conversion of native riparian ecosystems to commercial croplands and grazed rangelands as the primary cause in Wyoming

POPULATION TREND: A scarcity of historical demographic data makes population trends difficult to determine, though it is known that the Preble’s meadow jumping mouse no longer inhabits a number of sites where it was found in the past. The species is clearly in decline in significant portions of its range.
