Mammals Corridors Urban Wilderness Big Engineering North America

Los Angeles is well known for its celebrities, so when the fearless cougar P-22 gained fame for making its home in the midst of the city, he inspired an effort to build the world’s largest wildlife crossing and helped spark a national campaign to support crossings and corridors everywhere.

When he came of age, P-22, like other young male mountain lions, set off to find territory and potential mates. Against all odds, he successfully traversed multiple freeways to find a new home in Griffith Park. However, this small scrap of land, like the Santa Monica Mountains he came from, remained isolated from larger mountain ranges to the east. 

After years of research and outreach by local biologists and advocates like Beth Pratt, this team of conservationists pinpointed the vital location for a wildlife crossing to be built to restitch an entire ecosystem. Now a decade later, P-22’s story continues to inspire the very construction of this landmark crossing and expands what’s possible for urban wildlife coexistence.
