CPW Pika Shapefile Download

Updated December, 2025 PikaOverallRange is an ESRI shapefile encompassing the observed and predicted range of a population of American Pika in Colorado. American Pika is primarily associated with talus and rockpiles near fields fringed by suitable vegetation in alpine and subalpine mountain areas. This information was derived from species experts. A variety of data capture techniques were used including implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). Various sources were referenced in developing these data including Mammals of Colorado; areas delineated by predictive modeling using various Colorado American Pika collection records, elevation ranges, slope ranges, aspect ranges, and SWReGAP vegetation classes; 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.
