The Mattole Restoration Council, the Mattole Salmon Group, Sanctuary Forest, the Mill Creek Watershed Conservancy, the Upper Mattole River and Forest Cooperative and the Mattole River and Range Partnership fosters the Mattole River habitat restoration work and serves as a model for other communities wanting to work cooperatively to repair anadromous salmonid habitat. Recently the group planned a pilot project to decrease winter runoff and increase summer flows, by using a model of beaver dams and pools. Research done by an ecosystem analyst from the Northwest Fisheries Science Center of NOAA Fisheries shows that salmon smolt production per beaver dam ranges from 527 to 1,174 fish, whereas production in a pool formed by large woody debris is only 6 to 15 fish. This suggests that re-establishment of beaver populations would be 80 times more effective in salmonid recovery efforts than placement along of large woody debris.
