Preble's meadow jumping mouse

One species that is found almost exclusively in heavily vegetated riparian areas is the Preble’s meadow jumping mouse (Zapus hudsonius preblei), a subspecies recently listed as threatened by the U.S. Fish and Wildlife Service (Figure 4). It is presently known to occur in seven counties along the Front Range of Colorado and two counties in Wyoming. Historical records indicate that it was formerly present in a few additional counties in both states. Habitat loss and degradation caused by agricultural, residential, commercial, and industrial development are believed to imperil its continued existence.

Much of the remaining habitat for the mouse occurs in areas with known or potential sand and gravel resources, which are being mapped as part of the Front Range Infrastructure Resources Project. We are also cooperating with the Colorado Division of Wildlife to develop detailed maps of riparian vegetation in parts of the Front Range and with the Colorado Natural Heritage Program to compile data on locations where the mouse has been trapped. We will combine this information in a geographic information system to analyze the relationship between mouse locations, riparian vegetation, and sand and gravel resources. We will work closely with other scientists who are studying the mouse to determine how best to use these data to identify areas of potential mouse habitat. Data on specific habitat requirements of the mouse may also be useful in developing guidelines for reclaiming sand and gravel pits to benefit this threatened species.
