Manzanita Greening & Canyon Health Project

San Diego Canyonlands (Proponent), in partnership with the City, proposes to conserve, restore, protect, or enhance, and assist in the recovery of California native fish and wildlife, and the habitat upon which they depend. By restoring and enhancing native scrub oak chaparral, coastal sage scrub, and riparian habitats, the Project is expected to benefit California gnatcatcher (Polioptila californica californica), listed as threatened under the Endangered Species Act and Crotch’s bumble bee (Bombus crotchii), a candidate for listing under the California Endangered Species Act, among other native species. Streambed degradation, erosion, and invasive species proliferation within the Project area and the broader canyon has been an ongoing problem that has caused channel widening, scour, and head-cutting (creek incision) resulting in the likelihood of streambank failure and damage to surrounding habitat. To address these issues, the Project is designed to restore and protect habitat along a one-mile reach of Manzanita Creek, totaling approximately eight acres in area, by improving existing erosion and drainage issues, removing invasive species, reducing existing public access impacts, and implementing streambed restoration. Project includes hydrologic improvements, habitat restoration, streambed stabilization, and monitoring and maintenance.
