Project: Mount Tamalpais State Park: Dias Ridge Restoration and Trail Improvements

Description: This project will involve landscape restoration, trail improvements, new trail construction, and associated work on Dias Ridge at the Mount Tamalpais State Park. A major part of the project is the closure and restoration of eroded trail segments, ensuring the natural habitat of the surrounding area are restored in a manner that minimizes the potential for erosion, and support native plant habitat that is similar to surrounding areas. Approximately 2 miles of trail is anticipated to be closed and restored following the new trail construction. Existing trail segments will be retained where practical and construction of an improved trail alignment will be implemented to eliminate poorly graded and eroding segments. Remaining trail segments will be recontoured as necessary to restore the natural land contours and drainage patterns of the site. Approximately 11 acres of native habitats (coyote brush, coastal scrub/coastal grassland, grassland and oak/bay woodland) will be restored. Restoration will also include control of invasive non-native plant species populations. A twenty-eight foot long multi-use wooden bridge will be constructed to span across Frank Valley Creek.
