Puma and Mountain Lion Welfare in the American West: Human-Wildlife Interface

Pumas face growing conflict with human development in the American West. Understanding welfare implications of vehicle strikes, habitat fragmentation, and lethal management is important.

Key Facts

An estimated 30,000 mountain lions live in western North America
Vehicle strikes are a significant source of puma mortality in fragmented landscapes
Conflict with livestock leads to lethal control by ranchers in some states
California banned hunting of mountain lions in 1990 and populations have stabilised
Wildlife crossings reduce vehicle strike mortality significantly where implemented
GPS collaring studies show pumas avoid human activity but are increasingly constrained

Welfare Considerations

Puma welfare is closely linked to landscape connectivity. Vehicle strikes cause acute trauma and slow death in injured survivors. Lethal control for livestock depredation ends with shooting or trapping, both causing acute suffering when not carried out swiftly. Non-lethal deterrence - guardian animals, lights, and enclosures - reduces conflict without welfare cost. Wildlife crossings are high-value infrastructure for individual welfare and population viability.

What You Can Do

Support wildlife crossing campaigns in high-mortality puma road sections
Advocate for non-lethal conflict resolution over lethal control of pumas
Support mountain lion coexistence initiatives working with ranchers
