Pronghorn Migration and Welfare on the Range

The pronghorn antelope undertakes one of North America longest land migrations, and protecting their ancient pathways is essential for both population survival and individual animal welfare.

Key Facts

Pronghorns migrate up to 300 miles each year along ancient corridors in the Greater Yellowstone ecosystem
They can run at sustained speeds of 55 mph — the fastest land animal in the Western Hemisphere
Fencing blocks pronghorn migration routes since they do not jump fences like deer
The Path of the Pronghorn was established as the first federally protected wildlife migration corridor in 2008
Climate change is shifting vegetation timing and disrupting the seasonal cues pronghorns rely on

Welfare Considerations

Pronghorn migration welfare depends on the integrity of ancient movement corridors that have been traversed by their ancestors for thousands of years. Fences, roads, and development that break these corridors trap animals in unsuitable seasonal habitats, causing food stress, exposure, and death. Retrofitting existing fences with low clearance gaps and high bottom wires allows pronghorns to pass while maintaining livestock containment, demonstrating that coexistence solutions exist.

What You Can Do

Support organizations working to protect and restore pronghorn migration corridors
Advocate for wildlife-friendly fencing standards in pronghorn range states
Donate to programs mapping and securing critical migration pathways
Engage with ranchers about low-cost fence modifications that allow pronghorn passage
Learn about pronghorn ecology to appreciate their unique evolutionary adaptations and welfare needs
