Colorado Parks and Wildlife
BorealToadOverallRange is an ESRI SDE Feature Class showing Overall Range for Boreal Toad (Bufo boreas) in Colorado. Overall Range is defined as the area that encompasses all known activity areas within the observed range of a population of Boreal Toads. 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).
