In collaboration with several landowners across 500 feet of San Geronimo Creek, SPAWN has installed many large woody debris structures in the creek to slow bank erosion that was threatening private property and increased the instream complexity of the stream by reducing channel incision, creating pools, sorting sediments, and retaining stream gravels. The large woody debris structures help slow water downs, capturing gravels for spawning, adult and creating pools to provide cover and insect prey in pools for juvenile coho.
The project is also partnering with Lagunitas School District to restore 3,000 square feet of riparian habitat at the Lagunitas School, removing a dilapidated storage shed and sandbox from the banks of Larsen Creek, and planting hundreds of native plants and trees with the assistance of students and volunteers.
This project was funded by the California Department of Fish and Wildlife and Turtle Island Restoration Network. Engineering and design was provided by GeomorphDesigns and construction was done by Dragonfly Stream Enhancement and SPAWN.
