Pronghorn antelope make some of the longest overland migrations in North America, and their welfare depends on maintaining wildlife corridors through increasingly fenced and developed landscapes.
Pronghorn migration welfare is critically linked to landscape connectivity. Animals attempting to reach traditional winter ranges through blocked corridors face starvation when diverted from forage. Entanglement in barbed wire causes severe injuries including lacerations and broken legs that may result in prolonged suffering before death or rescue. Climate change is shifting both forage availability and weather patterns in ways that increase migration necessity while infrastructure development simultaneously blocks routes. Wildlife-friendly fencing modifications - lower bottom wire heights and smooth wire in lower strands - dramatically reduce entanglement mortality at low cost. Wildlife crossings at major road barriers enable safe passage.
