The long-term downward trend in the health of local salmon runs marks a significant trend away from sustainability. Numerous local salmon runs have been extinct for decades, and we are in danger of losing many more if we do not take swift and effective action to preserve the integrity of our local watersheds. The health of salmon runs is linked to the economy, tourism, recreation, and food production, as well as to the environment. Salmon are affected by runoff from streets carries oil-based pollutants. Drainage from lawns and farms carry pesticides, fertilizer, and silt.
Construction can divert streams or change hydrology.
Poor forestry practices increase silt loading, disrupt food chains, and change water temperatures and runoff patterns. Dams make it difficult or impossible for salmon to return upstream, and often lethal to make the journey out to sea. Our demand for fish and the commercial fishing industry have the potential to further decimate salmon stocks.
