Habitat Restoration

The majority of MCRCD’s habitat restoration projects have focused on enhancing stream habitat for listed species such as coho salmon, steelhead trout, and Chinook salmon. These projects include improved fish passage, enhanced instream habitat, increased streamside vegetation, invasive species eradication, and reducing sediment and other pollutants from entering streams and rivers. Steam enhancement work requires adhering to federal and state permitting requirements which include approved engineered plans, environmental assessments, permits, and compliance monitoring.

Bioengineering
Bioengineered restoration integrates nature into the landscape restoration design and has become a required element for most stream restoration projects in California. Bioengineered designs use native living material such as willows and other plants, and, with time, a bioengineered system gains strength and lasting stability as plant roots take hold and integrate with structural supports such as native rock, root wads, and downed trees. Traditional engineered designs that rely solely on concrete and metal, though strong at the time of installation, have the potential to fall apart over time and create fish passage barriers and other deleterious impacts.
