[1/2] National Park Service photo of the Griffith Park mountain lion known as P-22 is shown in this remote camera image set up on a fresh deer kill in Griffith Park in this November 2014 photo.
P-22, a radio-collared puma that became a wildlife celebrity, was one of the many mountain lions struck by a car in California.
The data adds to research showing mountain lions, also known as cougars or pumas, are under growing pressure from traffic and urban sprawl that have left their territories increasingly isolated from one another, shrinking their gene pools.
The study cataloged a total of 535 mountain lion deaths on some 15,000 miles (24,140 km)of state-managed highways over eight years, from 2015 through 2022.
A public celebration of P-22 is planned for Saturday in Griffith Park.
