ElkWinterConcentrationArea is an ESRI SDE Feature Class that shows
winter concentration areas for elk in the state of Colorado. This
dataset represents that part of the winter range of elk where densities
are at least 200% greater than the surrounding winter range density
during the average five winters out of ten from the first heavy snowfall
to spring green-up, or during a site specific period of winter as
defined for each Data Analysis Unit.
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=804abf2794b346828eeff285bffe9259) and will be updated from that location.
