Wild horses in North America and Australia represent a complex intersection of ecological management, cultural heritage and animal welfare ethics.
Round-up stress is significant: animals may run for kilometres in heat before capture, and injuries including leg fractures, myopathy and death occur regularly. Long-term holding facilities, while safer than culling, deprive horses of natural movement, social structure and grazing behaviour. Humane alternatives — fertility control, adoption incentives, and working with tourism industries — address population pressures with far less acute suffering. Advocate groups and researchers are pushing for these approaches at scale.
