PJ_MOUSE-occupied_range is an ESRI shapefile showing the Occupied Range for Preble's Meadow Jumping Mouse (Zapus hudsonius preblei) in Colorado. Occupied range is defined as those areas where Preble's are known to occur. These data are derived by combining known occurrences of Preble's with mapped riparian vegetation and applying a 1 mile buffer both upstream and downstream including both the main channel and side channels. Additionally, a 100 meter lateral buffer is applied which, in general, represents foraging and hibernaculum habitat. This buffer serves as a general guideline. Site specific topographic and vegetative features may increase or decrease the area considered locally as foraging and hibernaculum habitat....
PJ_MOUSE-overall_range is an ESRI shapefile showing the Overall Range for Preble's Meadow Jumping Mouse (Zapus hudsonius preblei) in Colorado. Overall Range is defined as the area which encompasses the probable range of Preble's Meadow Jumping Mouse along the Front Range of Colorado below 7600' elevation eastward to include those hydrounits identified by the Preble's Technical Working Group. Preble's Meadow Jumping Mouse is primarily associated with riparian corridors of small intermittent and perennial streams where riparian herbaceous and riparian shrub (primarily willow) dominate. The activity item has a value of 1; this value indicates the range for that activity. This information was derived from field personnel....
