Wadulh Lagoon Tidal Wetland Enhancement Project
This Project has an Update in progress.
Project Overview
Basics
Wadulh Lagoon Tidal Wetland Enhancement Project
Planning/Design
The HCRCD is partnering with the Humboldt Bay National Wildlife Refuge (HBNWR) to restore a 78-acre parcel on Mad River Slough in Humboldt Bay. The restoration project will include the re-establishment of tidal channels, eelgrass beds, and salt marsh. These components will provide significant off-channel and nursery habitat. Overall, the project will restore historical wetland types, increase adaptation to sea level rise, and provide habitat and wildlife protection. The project will assist in the recovery of threatened and endangered fish species, as well as special-status birds, amphibians, and plant species.

Project Themes
The removal of the dike will result in resiliency to changing ocean conditions and sea level rise. Restoration of the salt marsh will improve the ecosystem services including carbon sequestration.
Wiyot Tribe: Youth Education Day; Invasive Removal, Eco-cultural Interpretation.
Redwood Region Audubon Society: Guided bird-watching field trips, 2 per year.
Friends of the Dunes: Guided tours of the project, 2 per year, assistance with interpretive signage
The loss of salt marsh habitat within Humboldt Bay is an important factor contributing to the decline of salmon and steelhead, and many other fish species, including coastal cutthroat trout, and numerous plant and wildlife species, including Lyngbye’s sedge, Bald Eagle, Peregrine Falcon, Kestrel, Merlin, Sharp-shinned and Cooper’s Hawks, and Northern Red legged frog. Restoring the diked and drained salt marsh and intertidal areas will provide nursery habitat and fish passage for federally and state listed fish species and habitat for shorebirds and raptors.
