Mountain Lion Project

The Karen C. Drayer Wildlife Health Center has worked with mountain lions in Southern California since 2001, with particular focus on:

  • Habitat Use
  • Prey Animals
  • Health & Disease
  • Human Interaction, Attitudes and Behavior

We have placed GPS collars (and one VHS) on 65 lions to date. The collars allow us to track the movements and behavior and document habitat use. They also help us determine potential trapping sites. Using cage traps with road-killed deer for bait, we sedate the cats, take blood, DNA and feces samples to determine health, while also checking or applying collars.

The project has had great success using cage traps — a process far safer than snares or dogs, which continue to be the more prevalent capture methods. Learn more about our research here
