Basics
Alder Creek Erosion Control and Riparian Restoration Project
Completed
This project addresses bank erosion along a tributary of Dutch Bill Creek, an important salmonid habitat subwatershed of the lower Russian River, in western Sonoma County, CA. The project addresses three separate erosion sites located immediately downstream of the spillway outlet of an on-channel agricultural pond along the North Fork of Lancel Creek, a Dutch Bill tributary. Project components include the excavation of over-steepened and eroding banks at the three sites, placement of rock armor as bank protection at the upstream site, installation of cattle exclusion fencing, and revegetation of the project area.

| Explanation: | Construction to restore the streambank, combat erosion through grade stabilization, and install fencing was completed in August 2020.In 2021, plans were made to start the Riparian restoration through revegetation and willow sprigging, but these actions were not completed until early 2022. |

Project Themes
Project Themes
As part of the revegetation aspect of this project, Point Blue Conservation Science was contracted to facilitate the Students and Teachers Restoring A Watershed (STRAW) program. STRAW engaged students and teachers to participate in the revegetation of Alder Creek Ranch by installing 40 plants to restore the native plant species cover of the area.
A number of species will benefit from successful project implementation, including coho salmon and steelhead trout. The project will reduce the erosion of fine sediment from failing banks at the site, leading to improvements in critical spawning and rearing habitat downstream.
These include spawning gravels that are less subject to embedding by fines (which reduced the flow of oxygenated water to eggs and newly hatched alevins), and lower rates of pool filling by fine sediment (increasing pool volume and available cover for rearing fish).
Erosion control will help improve the riparian zone, water quality, soil quality, and plant health. Reestablishing riparian vegetation at the project site will shade the creek and reduce water temperatures during the summer/fall dry season, also benefitting rearing juvenile fish downstream. In addition, numerous bird species will benefit by the improvement of foraging and nesting habitat in the riparian zone, and the diverse riparian vegetation will provide benefits for other wildlife species, including amphibians.
