Mountain lions, more closely related to housecats than lions, face challenging lives in Central California's urban wildlands. Their habitat is fragmented by freeways and development. Despite their wild nature, puma kittens behave much like domestic cats, and their mothers even purr. (Footage courtesy of the National Park Service)

The Center for Biological Diversity, a Tucson-based 501c3 nonprofit, believes human welfare is deeply linked to nature's biodiversity. We use science, law, and creative media to protect species on the brink of extinction and safeguard the lands, waters, and climate they need. Our mission is to ensure future generations inherit a world where the wild thrives.

Los Angeles is one of only two megacities globally where big cats, specifically mountain lions, live within city limits; Mumbai is the other. These mountain lions inhabit the Santa Monica Mountains, just north of the city, including the Santa Monica Mountains National Recreation Area.

A new report highlights the critical importance of wildlife crossings. These crossings enable Southern California mountain lions to navigate fragmented landscapes safely and significantly reduce the risk of vehicle collisions. Learn more about this vital conservation effort.

The Center's Urban Wildlands program protects big cats and other wildlife by halting urban sprawl into adjacent wildlands, ensuring vital space and connectivity. Uncontrolled development in these areas heightens fire risk, increases car dependency, and isolates wildlife populations, particularly mountain lions. This year, significant progress was made in securing greater protections for California's mountain lions and stopping harmful projects.

Learn more about our efforts to safeguard California's mountain lions and wildlife corridors, and discover how you can contribute. The program features insights from Dr. Tiffany Yap, a senior scientist and wildlife corridor advocate, and J.P. Rose, Urban Wildlands Staff Attorney.
