SAN FRANCISCO (AP) — Busy freeways running alongside park land and marshes make San Francisco Bay Area roads a “ring of death” for wildlife, according to a new statewide roadkill report that tracks the deadliest traffic spots for wildlife. Fraser Shilling, co-director of the Road Ecology Center at the University of California-Davis, used 29,000 volunteer reports of wildlife roadkill over five years to map the most lethal areas for the state’s 680 native species of bobcats, barn owls, frogs and other vertebrates. The idea is to identify stretches that need immediate action to try to protect wildlife — and to make clear the overall toll that California’s car culture is taking on native species, Shilling said.
