PronghornConcentrationArea is an ESRI SDE Feature Class showing
Concentration Areas of Pronghorn Antelope. Concentration Area is
defined as that part of the overall range where densities are at least
200% greater than the surrounding area during a season other than winter.
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=658ca28f48d4451f9eb4d60e3e9b573d) and will be updated from that location.
