Populations of wild Pacific salmon and steelhead (Oncorhynchus sp.) in the eastern Pacific Rim have experienced significant declines in abundance and associated genetic and life history diversity over the course of the twentieth century (Nehlson et al 1991, Slaney et al 1996, Myers et al 1998, Lichatowich 1999). In the Pacific Northwest of the United States, declines in the abundance of most populations accelerated in the last two decades of the century and have continued into the first two decades of the twenty-first (Busby et al 1996, Myers et al. 1998, Good et al.2005, Hard et al. 2007, Ford et al. 2011).
