Research overview: P-22, the puma of Griffith Park in central Los Angeles

P-22 became the most famous urban mountain lion in the world after crossing two of the busiest freeways in the United States to settle in Griffith Park, a small island of habitat surrounded by central Los Angeles. This overview synthesises what biologists learned tracking him for roughly a decade: an unusually tiny home range for a male puma, a solitary life with no mates reaching his isolated patch, documented rodenticide exposure with associated mange, a notorious incident involving a captive koala, and his role as a charismatic ambassador for wildlife-crossing advocacy. It frames his story as a case study in the costs and possibilities of large-carnivore life inside a megacity.
