Staff and volunteers doing stewardship work in Muir Woods.

For over 30 years, the park has celebrated Earth Day in Muir Woods with the support of countless volunteers. Traditionally, this workday has been held in winter since it is the perfect time to care for vegetation and perform maintenance in the woods. However, this year we are thrilled to be celebrating the occasion in April!

Join us at Muir Woods on April 24th and experience the majesty of the redwoods while lending a hand. Projects will range from habitat restoration to boardwalk care. Registration Required

Project Details:

  • Gully Stuffing: Help heal the landscape and slow the flow! Water is a precious resource, especially for Redwood Trees and Coho salmon. Volunteers in this project will install large branches and sticks into eroding gullies on the valley floor, allowing for more water to be retained in the Woods.
  • Deck Flossing: Help us prolong the life of the Muir Woods Boardwalk! We will be removing dirt, duff, and debris from between the spaces of the redwood deck boards, a process known as "deck flossing"! This is a fun family-friendly volunteer project, volunteers of all ages are welcome.
  • Weeding project: Give weeds the boot! Help remove invasive forget-me-nots and veldt grass from an important stream in the little visited Conlon Creek area of Muir Woods. This small valley is critical habitat to salmon and northern spotted owls!

All projects will range from 0.5 - 2 miles of walking, sometimes off-trail, and involve using small hand tools. We’ll provide more details and assign projects upon arrival.
