Where humans and nature collide:
Roadkill hot spots identified in California
Date:
April 20, 2015
Source:
University of California, Davis
Summary:
A map shows how California's state highway
system is
strewn with roadkill "hot spots," which are
identified in
a newly released report. The data could
help state
highway planners take measures to
protect both
drivers and wildlife.
system is
strewn with roadkill "hot spots," which are

a newly released report. The data could
help state
highway planners take measures to
protect both
drivers and wildlife.
Major hot spots include:
- Sacramento area: Where I-80 and I-5 run
- across by
- passes along the Pacific Flyway, marshy
- areas attract
- birds during migration and result in high
- rates of roadkill.
- Bay Area: "It's sort of a ring of death
- around the Bay
- Area,
- " Shilling said. Interstate 80 and State
- Route 101 run
- alongside the bay, where high rates
- of wading birds
- and water birds are killed. Large animals
- are more
- likely to be hit on I-280 and State Route
- 17,
- particularly near areas of parks and open
- spaces.
- Southern California: Many areas along
- State Route
- 94 in San Diego County have high rates
- of collisions
- where the highway runs through wildlife
- habitat.
- Shilling said Caltrans is planning to build
- five new
- wildlife-crossing structures in this area
- because the
- data demonstrate both an immediate
- need and
- locations where structures would be
- useful.
- Sierra: Highway 70 in Plumas County
- and near
- Portola has high rates of roadkill,
- particularly deer.
- North Coast: Both State Routes 101
- and 20 show
- high rates of collision between Willits
- and Lake
- Mendocino.
