Colorado Parks & Wildlife - Species Data - Least Tern Foraging Area
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
LeastTernForagingArea is an ESRI SDE Feature Class showing an area which generally is associated with a nesting area and which provides a source of food for Least Terns. Appropriate habitat includes shallow water areas in lakes, ponds, and river backwater areas with abundant small fish populations. These areas generally are within one-half mile of the nesting area. On large irrigation reservoirs, these areas fluctuate with changing water levels. 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).
