Because of their iconic cultural and economic status throughout the NPLCC, anadromous fish provide perhaps the best example of a highly valued natural resource likely to be influenced by climate-driven changes in hydrologic regime. These species (including the five “salmon” species, populations of steelhead, coastal cutthroats, the bull trout/arctic char/Dolly Varden complex and lamprey) have served the nutritional and ceremonial needs of indigenous peoples for millennia.
This gallery brings together data sets related to anadromous fish from multiple sources. The primary focus is on datasets that are consistent across the entire NPLCC geography. From there, a number of different landscape-scale data sets related to anadromous fish are provided, based upon ecoregional or political geographies.
