SAN FRANCISCO (September 5, 2023)—The National Park Service, California State Parks, Marin Water, Marin County Parks, and the Golden Gate National Parks Conservancy working in partnership as One Tam, have released the Marin Regional Forest Health Strategy (Forest Health Strategy), laying out a new model for understanding and caring for forests collaboratively at a meaningful scale in Marin County. Over a third of Marin is blanketed in a mosaic of forests—184 square miles covering an area four times the size of San Francisco. 

The Forest Health Strategy really helps us to look at the big picture and be able to take actions that make sense at the landscape scale, not just within any one jurisdiction's lands,” said Alison Forrestel, Chief of Natural Resources and Science for the Golden Gate National Recreation Area.

The innovative approach to forest stewardship in the Forest Health Strategy brings together community engagement, environmental justice, climate planning, and best available science to protect and improve forest health and resilience in Marin County over the next decade.

Today, forests face threats such as introduced diseases and weeds, absence of fire, climate change, and others. To address the impacts of such threats, the Forest Health Strategy achieves the following new and necessary pieces for protecting forests: 

  • Describes the current condition of key forest communities in Marin County, and how to address threats that currently impact them
  • Uses best available data, local knowledge, and expert analysis to identify how and where agencies can make a difference for forests, working both independently and together across jurisdictional boundaries
  • Establishes a meaningful baseline to measure future changes in forests, through critical new datasets and methods to build upon
  • Delivers a thoughtful path forward for projects and programs designed to protect and improve forest health and resilience in Marin County over the next decade, including a suite of implementation-ready projects

The Forest Health Strategy’s development was led by One Tam, and contributors included One Tam partner staff and scientists, consultants, and the Federated Indians of Graton Rancheria (the Tribe). The Tribe is the only federally recognized Tribe whose ancestral territory is present-day Marin County. One Tam continues to consult and collaborate with the Tribe to inform this strategy and our future endeavors to ensure the Tribe’s perspectives and experiences are part of One Tam efforts. One Tam is also collaborating with the Marin Wildfire Prevention Authority and fire agencies on data and information sharing and will partner with them on future projects where there are opportunities for work that can both restore forests and increase public safety. While developed by public lands agencies in southern Marin, it can be a guide for work County-wide, and serve as a model for other regions working to protect forests.

Everyone has a role in our collective efforts to protect Marin’s special places. Learn more at
