20250913 16372900 1.0 TRUE Columbian Sharp Tailed Grouse Winter Range_309E1 CSTGrouseWinterRange is an ESRI SDE Feature Class showing winter range for Columbian Sharp-tailed Grouse (Tympanuchus phasianellus columbianus) in Colorado. Winter Range is defined as the observed winter range, usually in a tall shrub vegetative type, within 5 km of a lek site. Shrub height should be sufficient to allow feeding on buds by birds above normal snow depths. 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). Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers.
