Press Release
LANDER, WYOMING (March 4, 2025) — Yesterday, the Wyoming Game and Fish Department announced a new phase in the process to designate the Sublette Pronghorn migration corridor, releasing a comprehensive Biological Risk and Opportunity Assessment. This report outlines specific threats to migration and opportunities for conservation along 10 discrete segments of the migration corridor. This marks an important step in the process to officially designate the migration corridor, initiating a formal public comment period that runs through May 2.
In response, the Wyoming Outdoor Council issued the following statement:
“We at the Wyoming Outdoor Council congratulate Department biologists on their thorough analysis of the Sublette Pronghorn migration. The Biological Risk and Opportunity Assessment clearly demonstrates the need to designate this migration corridor,” Meghan Riley, wildlife program manager for WOC, said. “The level of detail, not to mention the years of data and work, that went into this assessment are truly astounding.”
After the harsh winter of 2022–23 drastically reduced the Sublette herd’s population, alleviating pressure from development in key migratory habitat is imperative for its recovery. Animals that were able to migrate further south experienced higher survival rates than pronghorn that overwintered to the north, clearly demonstrating the need to protect connectivity between seasonal ranges.
“This population took a huge hit, especially in the north of the herd’s range. Recovery is slow-going and precarious, given existing and anticipated threats to corridor functionality,” Riley said. “With widespread public support for conserving this herd’s migratory habitat, it is our hope that the Game and Fish Commission heeds the call to protect this storied herd of pronghorn for current and future generations to enjoy.”
Following an analysis of public comments, Game and Fish will present its case for designation to the Wyoming Game and Fish Commission at their July meeting. At this time, commissioners will vote on whether or not to recommend designation of the Sublette Pronghorn migration corridor to the governor.
