Last month, two of our region’s most iconic wild residents — a mountain lion and a black bear — were killed by vehicles on Highway 101. The bear near Summerland, the mountain lion near the Castillo Street exit in downtown Santa Barbara.

These fatalities aren’t isolated incidents. They’re part of a heartbreaking and predictable pattern throughout California, especially here along the Central Coast where Los Padres National Forest meets a fragmented human landscape.

Wildlife forced to navigate our highways are gambling with their lives and, too often, they lose.

Mountain lions in our region already face steep odds. Isolated by roads and development, they suffer from inbreeding, territorial conflicts and habitat loss. Vehicle collisions remain one of the leading causes of death.

The young lion killed last month was likely dispersing, looking for new territory or a mate, which is a natural, essential behavior made deadly by modern infrastructure.

The bear’s death is equally tragic. Black bears play a crucial ecological role in our oak woodlands and chaparral landscapes. They help spread seeds, regulate insect populations and support the balance of these ecosystems.

But as their movements bring them closer to highways like the 101, too many are dying in avoidable accidents.

The good news? We know how to fix this.

Wildlife crossings — specially designed overpasses and underpasses that let animals safely pass beneath or above roadways — save lives.

From Banff National Park in Canada to the Liberty Canyon crossing currently under construction in Agoura Hills, these structures dramatically reduce animal-vehicle collisions while reconnecting critical habitat.

Approximately 1.5 million wildlife-vehicle collisions occur yearly, causing 26,000 driver and passenger injuries annually.

Our region is long overdue for wildlife crossing solutions. Numerous conservationists, scientists and local advocates are working with state and regional transportation planners to prioritize corridors in transportation projects along the Central Coast.

The recent deaths on Highway 101 should be the final wake-up call. What’s needed now is the public will and political leadership. Assembly Bill 902, the “Connected Communities Act,” will help to make these crossings a reality.

If we want future generations to grow up where mountain lions still roam the backcountry and black bears have room to wander, we must act now.
