As a whole, the 2013 report showed positive trends in reducing pollution in the aquatic food web, but showed continuing declines across aquatic habitat and species based indicators. More specifically, the report shows improved air quality, improved freshwater water quality and reductions in persistent toxic chemicals in the aquatic food web. The indicators representing populations of wild species, including marine species at risk and Chinook salmon abundance, need more attention. Two habitat indicators sensitive to climate change, summer stream flow and marine water quality, are also showing declining trends. News release:
