CPW Olive-backed Pocket Mouse Shapefile Download

Updated December, 2025 OliveBackedPocketMouseOverallRange is an ESRI shapefile showing the Overall Range for Olive-backed Pocket Mouse (Perognathus fasciatus) in Colorado. Overall Range is defined as the area which encompasses the probable range of Olive-backed Pocket Mouse in Colorado. Olive-backed Pocket Mouse is primarily associated with grassland in arid and semi-arid upland areas, usually with sparse vegetation and sometimes with scattered trees such as the aspen or cottonwood (Populus sp.) and plants such as the fringed sagebrush (Artemisia frigida). Its burrows are found in both sandy and clayey soils. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximinzing Mapping Resources. GeoWorld 16(3):32-35). Reference data included Mammals of Colorado and CPW Scientific Collection data. These data are updated on a four year rotation with one of the four Colorado Parks and Wildlife Regions updated each year. These data are not updated on a statewide level annually.
