Together, ensuring a vibrant and healthy future for Mt. Tam


Bothin Marsh

Bothin Marsh is a well-loved stretch of shoreline that offers much in the way of recreation and wildlife, with unique plants and animals surrounded by urban development. With climate change and sea level rise, flooding is increasing in frequency and duration on the Mill Valley-Sausalito Multi-Use Path (Bay Trail) and throughout Bothin Marsh. Learn more about the Bothin Marsh Open Space Preserve and the challenges it faces with climate change and sea level rise.

Bothin Marsh’s natural resources provide numerous ecological, economic, and social benefits to human visitors and neighbors. The land managers of Bothin Marsh Open Space Preserve have the responsibility of protecting an ecologically rich and beloved open space and recreational access. Land management decisions must not only be driven by the best science but also with community participation in caring for our shared open spaces. Click here to learn more about the process underway to create a shared community vision for Bothin Marsh.
