Habitat Restoration

Each year, SPAWN volunteers contribute hundreds of hours towards restoring streamside habitat in our community throughout the Lagunitas Creek Watershed.

Join us!  Our work relies on volunteers of all backgrounds (including students, families, biologists, scout groups and people from across the Bay Area) to restore and re-create riparian habitat that provides much needed shade for young salmon and trout in our local waterways.  We hold weekly Native Plant Nursery Days (see below), as well as Seed Collection Hikes and Restoration Workdays.

Over the next few years, we will conduct the Ten Thousand Redwoods Project to propagate native trees to reforest Lagunitas Creek and sequester carbon; restore one mile of Lagunitas Creek in partnership with the National Park Service; replant areas of the San Geronimo Golf Course and Samuel P. Taylor State Park; restore recreational trails in partnership with local land agencies; and plant redwoods to restore a former cement plant along the creek.

Native Plant Nursery

Our nursery, launched in 2006, is run with the energy and passion of local community members.  Join us every Friday from 10am – 1pm to prepare seeds, sow and tend native plants ranging from ferns to redwoods. The native plants you tend will be used for local stream restoration projects!

First time volunteers should RSVP to sign up and to receive directions to our nursery in Lagunitas.  Please email SPAWN Watershed Biologist Preston Brown at

Landowner Assistance

Local landowners play a key role in protecting our endangered salmon and maintaining the beauty of our local creeks. SPAWN provides technical consulting on erosion control and habitat improvement projects for streamside residents in the San Geronimo Valley.

Past projects have helped local landowners maintain dirt roads that were distributing unnecessary amounts of dirt into our streams, design environmentally friendly erosion controls and restore creek banks with natural materials.

SPAWN also responds to many calls from concerned citizens about problems or emergencies that impact our streams and rivers. Our staff and volunteers respond to these calls and help refer problems to the appropriate agencies if necessary or find ways to prevent or repair the problem. Learn more here.
