Colorado Parks & Wildlife - Species Data - Pronghorn Winter Concentration
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
PronghornWinterConcentrationArea is an ESRI SDE Feature Class showing Winter Concentration Areas of Pronghorn Antelope. Winter Concentration Area is defined as that part of the winter range where animal densities are at least 200% greater than the surrounding winter range density during the same period used to define winter range in the average five winters out of ten. 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. Maximizing Mapping Resources. GeoWorld 16(3):32-35).
