Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
PronghornWinterRange is an ESRI SDE Feature Class showing Pronghorn Winter Range, that part of the overall range where 90% of the individuals are located between the first heavy snowfall and spring green-up during the average five winters out of ten OR for a site specific period defined by Colorado Parks and Wildlife personnel for that Data Analysis Unit (DAU). Winter range is only delineated for migratory populations. On the Eastern Plains winter range is defined as specific areas where pronghorn are known to migrate to on a consistent basis. 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).
