In the concrete jungle of Los Angeles, life has become tough for the region’s native mountain lions, who are kept from roaming and mating in the Santa Monica Mountains by obstructions like freeways (not to mention they are also vulnerable to poisoning). P22, a lion who miraculously made his way to Griffith Park, where he is now stuck for life, was photographed and became the poster boy for efforts to built the Liberty Canyon wildlife crossing over the 101 freeway in Agoura Hills. The multi-million dollar project will get some funding from Caltrans but much of it has to come from private donors. Enter P-22 Day Festival: a collection of lion-inspired art and other exhibits along with music, food and other activities. Check out DnA’s coverage of the wildlife crossing.
