Colorado Parks & Wildlife - Species Data - Elk Winter Concentration Area
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
ElkWinterConcentrationArea is an ESRI SDE Feature Class that shows winter concentration areas for elk in the state of Colorado. This dataset represents that part of the winter range of elk where densities are at least 200% greater than the surrounding winter range density during the average five winters out of ten from the first heavy snowfall to spring green-up, or during a site specific period of winter as defined for each Data Analysis Unit. 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).
