P-45: The Studly Mountain Lion King of Malibu
Here's a really interesting New Yorker article about the mountain lions of the Santa Monica Mountains which run from Malibu to Griffith Park. The highways have isolated this area, in terms of mountain lions traveling. P-45, however, was able to cross a highway to get into this genetic island and sow his genes. The article describes the isolation of the mountain lions which may result in their extinction (in the Santa Monica Mountains) within 50 years...which is why a land bridge is going to be built in Agoura Hills.
On this map you can see the underpass at Liberty Canyon that they believe P-45 may have used to get across the 101 and into the Santa Monica Mountains. You can see there are gaps in the residential developments there that would allow a mountain lion to pass through without having to deal directly with humans. This is where the land bridge will be built.
