P6 was one of the females born to P2's litter with P1 in 2005. She was radio-collared and tracked for more than 1-year, but her collar prematurely failed in late 2006 and we lost track of her. These series of photos were taken by a remote camera and are our last photographic evidence of her. We are unsure if she is still alive. She did, however, have at least one litter of kittens (fathered by P1) that produced P13.

These are individuals that we have evidence of by remote camera. Given our limited manpower and resources to buy radio-collars and track individuals, we are unable to capture and track every single mountain lion individual roaming our study area. Help us learn more about these unknown mountain lions by donating (See 'What Can You Do' Page for more information)!

The National Park Service has been studying mountain lions, or pumas, in the Santa Monica Mountains National Recreations Area (SMMNRA) since 2002. During that time, biologists have captured, tagged, radio-collared and tracked 21 mountain lions. Presently only about 5 of those are still "on the air," meaning that they are alive with working radio-collars. The ones that have been humanely captured and tracked by biologists are included in this album. For more information on each individual, please see 'Mountain Lion Page.'
