WhPelicanNestingArea is an ESRI SDE Feature Class showing Nesting Areas for White Pelican (Pelecanus erythrorhyncos) in Colorado. Nesting Areas are defined as those islands and/or beach areas where any pelican nests are found. Human disturbance should be eliminated from these areas from April 15 to August 15. 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). Dataset was acquired from a...
PeregrineNestingArea is an ESRI SDE Feature Class showing Nesting Areas for Peregrine Falcons in Colorado. Nesting Area is defined as an area which includes good nesting sites and contains one or more active or inactive nest locations. The boundaries are drawn based on professional judgment to include most known nesting habitat in the vicinity. Usually these areas are mapped as polygons around cliffs and include a 2 mile buffer surrounding the cliffs. 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...
GBHeronNestingArea is an ESRI SDE Feature Classshowing Nesting Areas for Great Blue Heron (Ardea herodias) in Colorado. Nesting Areas are defined as individual trees or groups of trees containing nest platforms, and a buffer zone extending 500 meters around a known active or inactive nest site. Nest platforms are usually located in dominant trees associated with riparian habitats. 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.
