The unique welfare and conservation challenges facing pronghorn — North America's fastest land mammal — during their remarkable seasonal migrations across increasingly fragmented landscapes.
Pronghorn migration represents one of the most compelling examples of wildlife welfare intersecting with habitat conservation. Animals blocked from completing migration routes face nutritional stress, increased predation risk at unnatural congregation points, and reproductive failure. The barriers are largely anthropogenic — roads, fences, and development fragmentation — and therefore tractable. Individual pronghorn experiencing migration blockage suffer measurable welfare impacts including elevated cortisol, reduced body condition, and increased mortality. Restoring and protecting migration corridors is both a conservation imperative and a welfare intervention at population scale.
