Colorado Parks & Wildlife - Species Data - Bighorn Sheep Summer Range
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
BighornSummerRange is an ESRI SDE Feature Class showing Summer Range for Bighorn Sheep in Colorado. Summer Range is defined as that portion of the overall range where 90% of the individuals are located between spring green-up and the first heavy snowfall. Summer range is not exclusive of winter range; in some areas winter and summer ranges may overlap. 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).
