PROTECTION STATUS: Threatened
YEAR PLACED ON LIST: 1998
CRITICAL HABITAT: 411 miles of rivers and streams and 34,935 acres in Boulder, Broomfield, Douglas, El Paso, Jefferson, Larimer and Teller counties designated in 2010
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.
