Pronghorn undertake one of North America longest land migrations, and their welfare depends on maintaining the seasonal corridors that allow movement between summer and winter ranges.
Pronghorn migration welfare is fundamentally about corridor integrity — the ability of individual animals to complete seasonal movements that their physiology requires for nutritional adequacy across seasons. Fences that block migration force pronghorn to make dangerous road crossings or become trapped between barriers, creating chronic stress and potentially fatal situations. The welfare of migrating pronghorn depends on a chain of intact habitat from summer to winter range, each link of which must be maintained. Wildlife-friendly fencing modifications — raising the bottom wire and lowering the top wire — allow pronghorn passage while maintaining livestock containment, representing a simple and effective welfare intervention.
