Scientists call it a trophic cascade. We call it The Lion Effect.
Mountain lions influence far more than the animals they hunt. Their presence helps shape habitats, support biodiversity, and strengthen the natural systems that wildlife and people depend on.
We ensure that America’s Lion survives and flourishes in the wild. We protect mountain lions by advancing science, defending strong wildlife policies, helping communities coexist, and building a national movement for America’s lion.
Advancing research and understanding.
Promoting science-based wildlife policy.
Helping communities and wildlife thrive together.
Growing the partnerships, resources, and public support needed to protect mountain lions for the long term.
Mountain lion conservation is about more than a single species. It requires science to guide decisions, policies that support coexistence, communities that understand and value wildlife, and organizations strong enough to sustain long-term change.
That’s why our work spans research, advocacy, education, and partnership-building, because lasting conservation depends on all of them working together.
Speak up for science-based wildlife policy and help protect mountain lions and the landscapes they call home – now and in the future.
