Habitat degradation is more pronounced in lower elevation watersheds due to human influences that have altered disturbance and hydrologic regimes. Habitat remnants and ecological processes remain for rebuilding and maintaining functional terrestrial ecosystems . Centers of biodiversity and hot spots of rare, native species are identified. Key salmon species have experienced declines in habitat and abundance. These species are especially vulnerable at certain stages of their life cycle.
Habitat degradation is greatest in lower watersheds.
Core remnants and ecological processes remain for rebuilding and maintaining functioning systems. Overall scenic quality is high. Communities located in moist climates have higher resiliency. Conversely, communities in drier climates have fewer economic options and are less resilient. Ecosystem management requires strong cooperation among local governments and agencies.
