This is the dataset for project "Wildlife Connectivity and Which Median Barrier Designs Provide the Most Effective Permeability for Wildlife Crossings" (UCD-CT-FAST-085).
This research consists of two primary objectives: identifying opportunities, information gaps, existing resources and research needs by engaging non-government organizations, the California Department of Transportation, and the California Department of Fish and Wildlife biologists who expressed interest in working on this project; and with input from these biologists, conduct a preliminary investigation for at least 10 sites, each with concrete median barriers, cable guards or thrie-beam barriers, and vegetated/developed medians, for comparison of rates of wildlife-vehicle collisions with large and all wildlife, as indicators of wildlife connectivity.
Because of their position in the center of the traveled right-of-way, median barriers could affect wildlife movement across the right-of-way, decreasing wildlife connectivity. This project team coordinated and met with staff from several Caltrans Districts to gain understanding of their issues related to median barriers and wildlife permeability.
