A Preliminary Classification and Mapping of Salmon Ecological Systems

Table 1. Buffer distances and maximum elevation thresholds to define floodplain spatial extent..... 23 Table 2. Estimated total sockeye salmon run size (in thousands) for the Nushagak river watershed. Figure 2. Broad scale landscape processes and patterns such as climate and topography influence conditions at reach and microhabitat scales important for freshwater life stages of Pacific salmon, and can be used to characterize relevant habitat conditions at multiple scales over very large areas. 12 Figure 3. Habitat types (below) mapped from multispectral satellite imagery (above) on the Figure 4. Springbrook density is highly correlated with node density, and shallow shore density is highly correlated with mean floodplain width. .
