Description:
GPChickenOverallRange is an ESRI SDE Feature Class showing Colorado greater prairie chicken distribution. Maps are derived from records of lekking sites for greater prairie chickens. Leks may be classified as active, inactive or lek of unknown status. Classification is usually based on knowledge of population fluctuations and/or male attendance; leks are considered to identify important seasonal activity areas nearby. GPChickenOverallRange is an ESRI shapefile showing those areas which encompass all known seasonal activities within the observed range of the prairie chicken. This is currently defined as the mean distance of winter movements (6 km radius buffer zone around active lek sites). It does not include historic range.

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=da0762d17a75489094ae45ffd2532539) and will be updated from that location.

This wildlife distribution map is a product and property of Colorado Division of Wildlife, a division of the Colorado Department of Natural Resources. Care should be taken in interpreting these data. Written documents may accompany this map and should be referenced. The information portrayed on these maps should not replace field studies necessary for more localized planning efforts. The data are gathered at a variety of scales; discrepancies may become apparent at larger scales. The areas portrayed here are graphic representations of phenomena that are difficult to reduce to two dimensions. Animal distributions are fluid; animal populations and their habitats are dynamic.
