Dear Friend,

As the warm sunlight stretches into the evenings, it's official: Spring is fully under way and Tam is teaming with life!

All around the mountain, people are eager to get outside and reconnect with nature after the wet winter. Marin youth are already one step ahead! From trout release field trips to receiving an award for habitat restoration work, this is just the beginning. These young people are making a difference today and certainly will in the future. 

Don't miss your chance to join our upcoming events. From marshes to mountain, biking to walking, there is something for you.

See you out there!

Thanks to all who joined us on Friday, April 12 to celebrate the Marin Wildlife Picture Index Projects’ first three years!

We heard the findings directly from the scientists conducting the study, which indicate that overall, Mt. Tam’s wildlife is healthy.

We also enjoyed the company of neighbors, volunteers, and One Tam partners during a delightful happy hour, with refreshments provided by Headlands Brewing Co., MH Bread & Butter, Insalata’s, Comfort’s Café, and Nugget Market in Tiburon.

A special thanks to the hundreds of volunteers who make this work possible and will continue to help One Tam monitor the health of Mt. Tam’s wildlife.

The One Tam team is pleased to announce that we have begun the conceptual design process for restoration at Roy’s Redwoods Open Space Preserve.

Community input and site analysis through 2018 has been key to establishing restoration goals for the Preserve. View a summary of what we’ve learned in the latest edition of the San Geronimo Valley Community Center’s Stone Soup, or get all the details in the Site Analysis Technical Memo

As we embark on conceptual design, our goal is to enhance the health of the ecosystem while improving visitor experience. Specifically, we will explore opportunities to restore hydrologic function of the alluvial valley, improve redwood forest and wetland habitats, and guide visitors through an immersive and accessible experience of the redwoods.

We are looking forward to getting your feedback and input on conceptual designs. Stay tuned for ways to get involved this summer!


Bothin marsh adaptations on the move

Click on the photo above to explore the shared vision for Bothin Marsh.


Mill Valley’s 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. This project will model how innovative, nature-based techniques can support adaptation of this area, in our communities and throughout the Bay Area.

View “Evolving Shorelines”, the shared vision for Bothin Marsh, for more about the future of the marsh and the community’s shoreline. Hear about next steps and meet the project team at the Pathway Tile Mosaic event on May 4 or on a Walking tour of Mill Valley’s Living Shoreline, June 16.  


From Classroom to creek: Marin Students connect with tam through trout

Spring time isn’t just for wildflowers! It’s also an exciting time for some Marin students as they care for, learn about, and observe trout eggs develop into juvenile fish in their own classrooms.

Every April around 1,100 Marin students conclude their trout raising journey with a field trip to Bon Tempe Lake to release their trout.Trout in the Classroom, a statewide program of the California Department of Fish and Wildlife (CDFW), aims to educate students about the life cycle of trout and their function in our ecosystems, as well as to inspire the next the generation of environmental stewards.

Together with CDFW, dedicated Trout Unlimited volunteers, and the Marin Municipal Water District, One Tam helped to provide students with a memorable experience that we hope will foster a lifelong enthusiasm for Mt. Tam and its watershed.

One Tam's LINC 2018 Receives Marin County Achievement Award

The goal of One Tam’s program called Linking Individuals to their Natural Community (LINC) is to connect local youth to their natural environment while making a tangible impact. 

In 2018, they did just that!

Last month the alumni were presented with the Integrated Pest Management Achievement Award, which recognizes local efforts to eliminate pesticide use within the Marin County Integrated Pest Program. The award recognizes the students’ field work to restore native habitat by manually removing ice plant at Bothin Marsh, and Kent and Arambaru islands; yellow star thistle on Mt. Tamalpais; and French broom around Marin City’s national parks. Their efforts help Mt. Tam and our communities stay healthy!

Congratulations LINC Tam 2018!
