NOTE: This "Medium Use" segment of the corridor uses all the same metadata as the official migration corridor feature class layer except for the insertion of (Medium Use) to the Title, the insertion of "the medium use segment within" in the Summary, and a modified Process Step in Lineage. As per the Lineage Statement, medium use represented greater than 9% of the overall population. These data represent the WGFD edited version of statistically based polygons derived from GPS collar data on mule deer migrating in the Upper Green River Basin. The animals collared are from the Mesa, Ryegrass, and Superior winter ranges from 2003 through 2015. The GPS data were analyzed using the Brownian Bridge Movement Model (BBMM),which produced polygons based on where animals traversed from winter range to summer range (and back) and how much time they spent along the way. The original data were edited to be more manageable on the ground as the WGFD works with land management agencies during land use planning.
