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....

The grizzly bear distribution boundary delineates the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2000-2014. The distribution boundary was generated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation. The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone ecosystem during 2000 to 2014.
