Mountain lions face increasing human-wildlife conflict as development expands into their habitat, requiring coexistence strategies that protect both people and lion welfare.
Mountain lion welfare in human-dominated landscapes is primarily threatened by vehicle collisions on fragmented highways and retaliatory killing after livestock predation. Individual mountain lions killed on highways represent acute suffering but also remove individuals whose presence stabilizes local prey populations. Dispersing sub-adult lions are most vulnerable to human conflict as they search for territories in unfamiliar areas. Livestock predation events trigger retaliatory killing that removes established adults with knowledge of the landscape. Conservation programs including wildlife crossings, livestock protection support, and community education directly reduce mountain lion mortality from human conflict. The Coexistence Center and similar organizations demonstrate that conflict reduction is achievable through targeted interventions.
