Fisheries Studies

(Revised December 2005)

Mendocino Redwood Co., LLC (MRC) began conducting fisheries studies in conjunction with its watershed analysis program to identify fish distribution and abundance, fish habitat quality and quantity, as well as potential restoration or enhancement projects. We have been collaborating with several organizations to help us with this, including Trout Unlimited, Mendocino Fisheries Program, California Department of Fish and Game, California Conservation Corps, Mendocino County Resource Conservation District and others. Restoration projects include upgrading culvert sizes to improve fish passage and sediment transport capacity; replacing culverts with bridges to allow for better fish passage; introducing large woody debris to improve fish habitat; and abandoning roads and landings which contribute sediment to fish bearing streams.
