DAVIS — Tens of thousands of mountain lions, bears, bighorn sheep, squirrels, birds and lizards have met their fate in collisions with vehicles across California, according to a “roadkill” report that names a San Francisco Bay Area highway as the state’s deadliest for wildlife.

The study by the Road Ecology Center at the University of California, Davis is based on more than 44,000 California Highway Patrol traffic incidents involving animals between 2009 and 2020. Also included are more than 65,000 reports from people via the California Roadkill Observation System phone app.
