Willits Bypass Mitigation Project

Implementation
The Willits Bypass Mitigation Project is currently the largest active public wetlands mitigation project in the State of California. In 2015, MCRCD assumed long term management responsibility for the 2,087-acres of wet meadow, stream corridors, and oak woodlands. MCRCD staff manage and monitor grazing impacts to listed species, ecosystem function, and overall biological diversity. A non-wasting endowment through the National Fish & Wildlife Foundation is a permanent source of funding for management and monitoring of mitigation lands by MCRCD which will go on in perpetuity. Work focuses on Creating, enhancing, and improving sensitive native habitats primarily riparian corridors and wetlands.

Project Themes

Project Themes

MCRCD staff offer guided field tours to the public on the project. Curriculum focuses on the science of conservation and restoring native habitats. Local schools, colleges, clubs, organizations, and the general public are all welcomed to attend.
This project has a focus on preserving and enhancing populations of Baker's meadow foam (limnanthes bakeri) and North coast semaphore grass (Pleuropogon hooverianus). Additionally, MCRCD staff oversee stream channel monitoring maintenance for migratory channels and spawning habitats for Coho salmon.
