Description:
GBHeronHistoricNestArea is an ESRI SDE Feature Class showing Historic Nesting Areas for Great Blue Heron (Ardea herodias) in Colorado. Historic Nesting Areas are defined as a formerly active nesting area that has been destroyed or in which no courtship, breeding or brooding activity has been observed at any time in the last five years. 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).
