Two Year Study of Artificial Tunnels to Reduce Roadkill of CTS

In 2016 we completed a 2-year study of artificial tunnels beneath Fresno Avenue in Santa Rosa, which were installed to provide safe movement corridors between upland and aquatic habitats for California tiger salamander. The tunnels are coupled with drift fences that redirect salamanders away from the road, which will be connected as a though-street in the future, to reduce or prevent roadkill of this protected species.

Our study was conducted for the U.S. Fish and Wildlife Service to better understand the use of tunnels as a means to reduce mortality of CTS from road traffic.
