Study Description

The study analyzed the spatial and temporal patterns of wildlife movements and roadkill occurrences along U.S. 101 through the Study Area using systematic camera monitoring and roadkill surveys, along with assessments of existing infrastructure and surrounding land use. The final report, the Gaviota Pass Highway 101 Wildlife Connectivity Assessment (WCA), was prepared by ICF Jones and Stokes, Inc. with the purpose of gaining a better understanding of wildlife movement conditions within the Study Area and identifying opportunities to improve wildlife connectivity and reduce wildlife vehicle collisions. The WCA study focused on medium and large mammals, or Target Species, including American badger, American black bear, bobcat, coyote, feral pig, gray fox, mountain lion, mule deer, opossum, raccoon, red fox, ringtail, striped skunk, and western spotted skunk.

The WCA report is available by emailing Caltrans District 5 Senior Environmental Planner Mitch Dallas at
