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. Flenner. March 2003. Maximizing
Mapping Resources. GeoWorld 16(3):32-35).
Dataset was acquired from a third party distributor who obtained it from CDOW in January 2011. The authoritative data source is available on ArcGIS.com (http://www.arcgis.com/home/item.html?id=d79b9ee3389a44c1a6afc424c532c26d) and will be updated from that location.
