migration

The approval establishes restrictions on development for public lands within the corridor, particularly the twelve bottlenecks, prohibiting new surface development and banning any activity requiring a state permit during spring and fall when the Sublette antelope herd migrates.

Unlike the state, Teton County requires wildlife-friendly fences. Jackson may consider more this fall.

The migration route spans from the Tetons to the Red Desert. The designation guides how future development can happen within the corridor.

“Mountain Migrations” is filled with episodes about a defining trait of Westerners: They’re always on the move.

The program is already removing migration barriers on private land in Colorado, Idaho and Wyoming. Now, it’s coming to Utah.

Gov. Mark Gordon is reversing course from the state’s wildlife commission on pronghorn migration protections.

Tony Mong has captured video collar and other visual data that tells more about mule deer migration and the challenges they face navigating rugged terrain and development in the Cody area.

New maps from the U.S. Geological Survey (USGS) show the migration routes of several big game herds across the West.

Last winter’s deaths of thousands of Wyoming pronghorn increased interest in “conservation leases.” But where wildlife advocates see hope, energy and ranching interests fear an attack on the “Western way of life.”

While bald eagles are one of the biggest conservation success stories in the United States, golden eagle populations continue to struggle in the West as they face increasing threats from energy development, lead poisoning, and habitat loss. Wyoming is a key nesting area for the species – which is where a new, free online tool called RaptorMapper comes into play.
