Simple modifications to ranch fencing dramatically improve pronghorn welfare by allowing safe passage while maintaining livestock containment. Community-scale fence modification programmes deliver measurable population benefits.
Pronghorn fencing is a rare welfare problem with a simple, low-cost engineering solution. The modification — raising the bottom wire and lowering the top wire — costs less than $1 per metre of fence and is compatible with cattle containment. The welfare benefit is substantial: pronghorn that can complete their full migration maintain better body condition, higher reproductive success, and greater resilience to winter conditions. Community-scale fence modification programmes, coordinated between ranchers, wildlife agencies, and conservation organisations, multiply individual farm benefits into landscape-level connectivity gains. The willingness of landowners to modify fencing is the primary constraint — education, technical assistance, and cost-sharing programmes all help drive adoption.
