One of the objectives of the Scott River Watershed Council (SRWC) is to conserve and enhance the resources of the Scott River watershed. Anadromous fish are one of those resources. The SRWC wished to better direct its conservation efforts by identifying which activities and conditions in the Scott River watershed caused the greatest harm to anadromous fish. The Fish Committee of SRWC set out to accomplish this by assigning a sub-committee that would use a science-based process known as a limiting factors analysis (LFA). An LFA seeks to identify the most important environmental factors that are causing a population to decline and preventing its recovery. The information can then be used to direct efficient, effective restoration of habitat and improvement of management practices to restore anadromous species. Although the Fish Committee is concerned with steelhead, coho and Chinook salmon, the committee chose coho salmon as the focus of this LFA, because it is the most threatened. Many of the factors that limit coho salmon also limit the other anadromous species, so implementation of restoration actions for coho may help those species as well. The SRWC intends to use this LFA as a template for steelhead and Chinook LFA’s to be completed in the future. The sub-committee compiled of local citizens, landowners and agency representatives began by searching for and reviewing existing LFA’s to find an accepted protocol. It found a variety of approaches, rather than one standard protocol.
