Pronghorn Welfare: North America's Fastest Land Animal and Conservation Needs

Pronghorn are uniquely adapted to open plains and exceptional speed. Fencing, roads and habitat fragmentation threaten their welfare and population viability.

Key Facts

Pronghorn are the second-fastest land animals on Earth, reaching speeds of 88 km/h.
They evolved their speed as an adaptation to now-extinct North American predators.
Unlike deer, pronghorn cannot jump fences, making livestock fencing a major movement barrier.
Seasonal migrations of hundreds of kilometres are blocked by fencing and development.
Winter weather and blocked migration routes have caused mass mortality events.
Fence modification programmes using raised lower wires allow pronghorn to crawl underneath.

Welfare Considerations

Pronghorn welfare is inextricably linked to landscape connectivity. Animals blocked from historical migration routes face starvation, exposure and population fragmentation. The mismatch between their evolved need for unobstructed plains movement and a modern landscape of fences and roads creates chronic welfare problems invisible in normal times and catastrophic during harsh winters. Wildlife-friendly fence modification — raising the bottom wire to 45 cm and lowering the top to 1 metre — costs little and dramatically improves movement. Welfare-aware land management treats landscape permeability as an animal welfare issue, not just a conservation metric.

What You Can Do

Support wildlife-friendly fencing programmes that modify barriers to allow pronghorn passage.
Advocate for wildlife corridors in land use planning that accommodate pronghorn migration routes.
Donate to organisations working on pronghorn habitat connectivity in the American West.
Learn about the unique evolutionary history of pronghorn and why their welfare needs attention.
Support grazing management practices that balance livestock needs with wildlife movement.
