PronghornWinterConcentrationArea is an ESRI SDE Feature Class showing
Winter Concentration Areas of Pronghorn Antelope. Winter Concentration
Area is defined as that part of the winter range where animal densities

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.
