P-22’s source colony west of Hollywood is a notoriously fragile one. Cut-off by highways and development to other cougars, fewer than a dozen cats hang on by a genetic thread in the Santa Monica Mountains.

A wildlife corridor or bridge across Route 101 would provide exchange between cats beyond the Santa Monicas.
