Colorado Parks & Wildlife - Species Data - Bighorn Sheep Production Area
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
BighornProductionArea is an ESRI SDE Feature Class showing production (lambing) areas for bighorn sheep in Colorado. Production areas are defined as that part of the overall range occupied by pregnant females during a specific time period in the spring. This time period is May 1 to June 30 for Rocky Mtn bighorn sheep, and February 28 to May 1 for desert bighorn sheep. Only known production areas are mapped. 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).
