ElkMigrationCorridors is an ESRI SDE Feature Class depicting Migration Corridors for Elk in Colorado. Migration Corridors is defined as a specific mappable site through which large numbers of animals migrate and loss of which would change migration routes. 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).

This is a layer package created by the Colorado Parks and Wildlife GIS Unit in 2017 for distributing Colorado state parks and wildlife GIS data for public distribution.
