Sad news. P22 has been euthanized. He was suffering from illness and injury caused by a car accident and poison induced mange. We must do better to safeguard our native wildlife. We look forward to the Wallis Annenberg Wildlife Crossing helping to save the lives of wildlife in the future. RIP, P22. https://www.facebook.com/CaliforniaDFW/posts/pfbid0HXw3tY1muXBuu2ktB3DL2CHdJrK8WjZCgtBauto2Ld2zGaQ61imMgRXoxJDmCqkal

After receiving a comprehensive medical evaluation, CDFW has received a clear picture of the mountain lion P-22’s medical condition and overall health. He had several severe injuries and chronic health problems.

Farewell to a trailblazer. 💔

Early this morning, subadult male mountain lion P-90 was struck and killed by a vehicle on State Highway 33 in Oak View, just south of Ojai in Ventura County. After they were notified, he was picked up by biologists from the California Department of Fish and Wildlife (CDFW).

Born in the central Santa Monica Mountains, he was one of 13 kittens born during the "Summer of Kittens" in 2020, which included five mountain lion mothers giving birth in our study area.

P-90 was first captured and marked at the den on July 6, 2020, when he was about three weeks of age. P-90's father is suspected to be P-63.

His sibling, male P-89, was killed by a vehicle on the 101 Freeway on July 18, 2022.

P-90 had successfully crossed the 101 Freeway in Camarillo this past June. He crossed flat agricultural fields and eventually traveled to the Lake Casitas area in Los Padres National Forest.

This was actually his third time successfully crossing the 101 Freeway.

Soon after dispersing from his mother, P65, he crossed the 101 at Liberty Canyon, heading north into the Simi Hills on December 11, 2021. The next night he crossed the 101 again, heading back into the Santa Monica Mountains.

P-90 was just over two years old. He is the 7th lion in our study area to die from road mortality this year alone and the 5th radio-collared one.

During the 20-year study, 32 mountain lions were killed by a vehicle in our study area, which includes the Santa Monica Mountains, Simi Hills, Santa Susana Mountains, Verdugo Mountains, and Griffith Park. Biologists are currently tracking 11 mountain lions in the region with GPS radio collars.

Samples were collected from P-90 after he was killed Friday morning. A necropsy will be conducted.

Tomorrow, Earth Day, is the ground breaking of the Wallis Annenberg Wildlife Crossing Wildlife Crossing. The Wallis Annenberg Wildlife Crossing is a public-private partnership of monumental scope that has leveraged the expertise and leadership of dozens of organizations and institutions. It serves as a project for the next century and will provide a lasting benefit to the wildlife and ecology of the area for generations to come. Spanning over ten lanes of the 101 freeway in the Los Angeles area, when complete the crossing will be the largest in the world, the first of its kind in California, and a global model for urban wildlife conservation.
