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

Our Work

Our Work

One Tam Projects & Programs

One Tam combines the skills and resources of its five partners to support work that is vital to the health of the mountain, enriches the experience of its visitors, and inspires and educates a new generation of stewards. Our combined efforts include ecological restoration, trail improvements, wayfinding signage, wildlife monitoring, volunteer and youth programs,
and more.

You can learn more about our work, and how you can get involved, through the links below.

Priority Park Enhancement Work

Redwood Creek Trail Realignment
The proposed trail project, with 1.1 miles of realignment and two new bridges over the stream, will provide passage for horses and pedestrians and protect the creek and its inhabitants.
Bothin Marsh
With climate change and sea level rise, flooding is increasing in frequency and duration throughout Bothin Marsh - this project is creating a shared community vision for its future.

Roy’s Redwoods
Long loved by the San Geronimo Valley community, Roy’s Redwoods Open Space Preserve offers visitors an immersive experience in an old-growth redwood grove.
Forest Health & Resiliency
First seen in Marin County in the mid-1990s, Sudden Oak Death (SOD) has resulted in the death of millions of oak and tanoak trees in California and Oregon. This project will examine how different forestry practices affect carbon sequestration, water yield, and reforestation potential in SOD-infested areas.

Science & Conservation

Monarch Habitat Enhancement
One Tam partners are now working to identify monarch butterfly overwintering and breeding habitat for restoration in the region, and to plan enhancement efforts.
Tamalpais Bee Lab
One Tam is continuing our efforts to monitor and understand more about Mt. Tamalpais’ wild bees.
Marin Wildlife Watch
The One Tam partner agencies are using motion-activated cameras to study wildlife on public lands around Mt. Tamalpais.
Invasive Plant Monitoring & Management
This program builds on successful existing models to find and eliminate priority weeds and engage volunteers in caring for Mt. Tamalpais.
Large-scale Inventories & Monitoring
A comprehensive, big-picture view of the mountain’s resources will allow managers to prioritize restoration and protection efforts and allocate resources in new ways.
Rare Plant Program
This program helps coordinate data management, mapping, monitoring, and research, and be able to look beyond their borders to rare plant conservation across the mountain.
Bat Monitoring
Seldom seen and poorly studied, the lives and habits of Marin County’s bats are largely a mystery. However, bats are actually tremendously important parts of our communities.
