摘要

Many West Coast salmon and steelhead (Oncorhynchus spp.) stocks have declined substantially from their historic numbers and now are at a fraction of their historical abundance. There are multiple factors that contribute to these declines, including, particularly the loss of freshwater and estuarine habitat, periodic poor ocean conditions, and a variety of land-use practices which have impacted many watershed processes. These factors collectively led to the National Marine Fisheries Service (NMFS) listing of southern California steelhead as endangered under the Federal Endangered Species Act (ESA).
