Colorado Parks & Wildlife - Species Data - Elk Severe Winter Range
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
ElkSevereWinterRange is an ESRI SDE Feature Class that shows severe winter range for elk in the state of Colorado. This dataset represents that part of the overall range of elk where 90% of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten. The winter of 1983-1984 is a good example of a severe winter. 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).
