The Safe Roads and Wildlife Protection Act would require Caltrans and the California Department of Fish and Wildlife to identify wildlife barriers and prioritize crossings when building or improving roads and highways.

Many of us have never seen a mountain lion up close and personal, yet lions have a distinct presence among us. From security camera footage to social media posts of P-22 — the famed mountain lion in Southern California — you might think mountain lions are thriving. You’d be wrong.
Scientists fear that as their turf and their gene pool continue to shrink, cougars (as they sometimes are called) could go extinct within decades in regions where they now roam. Fast cars, rat poison and a fragmented habitat are just some of the deadly challenges faced by mountain lions and other imperiled species. When a lion known to biologists as P-54 was struck by a car and killed in June, her death marked three generations of mountain lions lost on dangerous roads in the Santa Monica Mountains. Her son had died months earlier and her mother died in 2018. A month later, P-89 died on the 101 Freeway in Los Angeles, becoming the fourth cougar in the area to die by car strikes in five months.
This grim reality has led me to join forces with Assemblymembers Ash Kalra and Kevin Mullin to introduce Assembly Bill 2344, which would bring more wildlife crossings to our highway system. By prioritizing and investing in freeway overpasses, underpasses and other critical improvements, we can make our roads safer for wildlife and drivers.
Butterflies, foxes, desert tortoises, California newts and other wildlife have lost their ability to move freely through their home ranges because of poorly planned roads and development.
The UC Davis Road Ecology Center has been tracking wildlife-vehicle collisions and identifying hotspots on our highways. From 2016 to 2020, more than 44,000 wildlife-vehicle crashes were reported on California roads, resulting in human deaths, injuries and property damage. Collisions with wildlife are believed to go vastly unreported.
Earlier this year, I joined the groundbreaking celebration in Agoura Hills of the Wallis Annenberg Wildlife Crossing, which will be the world’s largest wildlife bridge when it’s completed in 2025. Such a project should inspire us to do better across the state. Our bill, the Safe Roads and Wildlife Protection Act, would require Caltrans and the California Department of Fish and Wildlife to identify wildlife barriers and prioritize crossings when building or improving roads and highways.
These projects can be as simple as improving existing culverts or installing directional fencing to facilitate wildlife movement. They can also be overpasses and underpasses in areas with high rates of wildlife-vehicle collisions and where the movement of imperiled species is constrained.
Setting up a protocol for state agencies to gather roadkill data is crucial to this effort. We must be smart about allocating resources so we can prioritize the most dangerous roads and make them safer for motorists and wildlife.
I know my legislative colleagues believe that improving road safety is a bipartisan priority. In states that are ahead of California in implementing crossings, wildlife-vehicle collisions have been reduced by up to 98% in areas with crossings. Simply put, wildlife crossings work. The question is: Are public safety and environmental protection worth the investment?
Our constituents would say yes, because Californians love and value our state’s rich biodiversity.
A UCLA-led study published earlier this year found that reproductive signs of inbreeding in Southern California mountain lions, notably an abnormal sperm rate of 93%, are much more serious than previously thought. Without safe routes for these iconic cats, the maze of freeways and sprawl development will only prolong genetic isolation and lead to local extinction.
It’s demoralizing to witness the decline of mountain lions knowing that wildlife crossings are an effective way to help them thrive. We shouldn’t sit on that knowledge and do nothing: We should make wildlife crossings a priority.
