One Tam: many ways to give back to the mountain that gives us so much

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.

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. Bothin Marsh will likely see ten inches of sea level rise in the next ten years. One Tam, with community partners and community members, is urgently working to adapt the marsh ecosystem and the Mill Valley/Sausalito Multi-use Path to sea level rise. Easily accessible and highly visible, Bothin Marsh is uniquely positioned to model how innovative, nature-based techniques can support adaptation of this area and be applied elsewhere in our communities and throughout the Bay Area.
