California Senate Bill 790 (SB790), passed in 2021, allows the California Department of Fish and Wildlife (CDFW) to grant compensatory mitigation credits for Wildlife Connectivity Actions. These actions aim to improve habitat connectivity, migration, recolonization, and breeding opportunities that have been disrupted by infrastructure or habitat fragmentation. In September 2024, CDFW released the Wildlife Connectivity Advance Mitigation Guidelines, outlining how credits will be calculated based on two variables: a “Credit Scoring” system (0-100) and a “Crediting Factor” to be developed through six pilot projects. One such pilot project is the creation of a wildlife undercrossing along Highway 17 in Santa Clara County, designed to benefit multiple special-status species. In collaboration with the Midpeninsula Regional Open Space District, Integral biologists have developed a method to calculate the Crediting Factor by assessing ecological value improvements from the project. Using species-specific indices derived from quantitative and qualitative data, this method has received tentative approval from CDFW and collaboration is ongoing. This work advances the process for approving future Wildlife Connectivity Actions, paving the way for increased funding and efforts to reconnect habitats and promote ecosystem health.
