Los Osos Creek Wetland Restoration: Implementation

Building on the RCD’s planning efforts and restoration plan for the Los Osos Creek Wetland property, funding from the USFWS National Coastal Wetland Program, the State Coastal Conservancy, and the Wildlife Conservation Boards Habitat Enhancement and Restoration Program, the RCD completed initial restoration activities in fall 2021. 

These initial restoration activities included reconnecting the historic floodplain connectivity by breaching 400 feet of levee and replacing three perched culverts with fish-passage-friendly low-water crossing. Construction took place during four weeks and was completed days before the first rains of the season. During construction activities, RCD staff saw more than 60 California red-legged frogs, a pair of Cooper’s hawks, a family of black-tailed deer and evidence of a mountain lion.

Restoration activities continue in 2022 with native riparian and upland plantings, including an outplanting of the Federally Endangered Marsh sandwort, supported by the USFWS, and removal of invasive cape ivy and iceplant.

Once complete, 50 acres of wetland and 16 acres of coastal dune scrub habitat will be restored, and a key barrier to fish passage will be removed, enhancing habitat for Steelhead, Tidewater goby, California redlegged frog, Morro shoulderband snail, Least Bell’s vireo, Marsh sandwort and Morro manzanita.
