Save California's Mountain Lions

Because of supporters like you, mountain lions in Southern California and along the Central Coast are now officially listed as threatened under the California Endangered Species Act (CESA).

This landmark protection follows years of advocacy, scientific engagement, and public education — work that the Mountain Lion Foundation helped lead. From elevating the science, to mobilizing public support, to standing before the California Fish and Game Commission as the voice for lions, MLF played a critical role in achieving this outcome.

The threatened listing recognizes what research has long shown: these isolated lion populations face serious risks from habitat loss, fragmentation, and declining genetic diversity. With this new designation, stronger protections are now in place to safeguard critical habitat, improve connectivity, and support long-term recovery.

This victory belongs to you.

Your commitment makes it possible for MLF to advocate effectively, advance science-based policy, and ensure that mountain lions remain part of California’s future. And the work is not finished. Implementation, habitat protection, and coexistence efforts will determine whether these protections succeed.

Please consider making a gift today to help carry this momentum forward — for Southern California’s lions and for mountain lions across their range.

Together, we are securing a future where America’s lion remains wild and free.
