SDC Property Boundary (white outline)

Sonoma Land Trust has a long history of advocating for urban spaces where wildlife can thrive. Our involvement with SDC is focused on those key spaces that are known pathways for our rich and diverse wildlife population. The Sonoma Valley Wildlife Corridor which runs through the Sonoma Developmental Center (SDC) is a critical access way for numerous species for safe passage between green spaces that make up a network of thriving habitats in Sonoma. These critical pathways, which provide access to food and water, are at serious risk of obstruction or abandonment if proper considerations are not made when redeveloping the SDC main campus. 

Sonoma Land Trust understands the necessary considerations that are essential to ensure that the irreplaceable corridor value of SDC campus and adjacent open space remain viable options for wildlife movement and health. We have, and will continue to offer our expertise and funding to the state and county decision makers involved in shaping the future of SDC’s campus for wildlife corridor conservation and enhancement.
