Food for Thought

In the Pacific Northwest (WA, OR, CA), many watersheds receive up to 90-95% fewer spawning salmon (by biomass) compared to historic conditions of the late 18th and early 19th century, and this may have profound implications for the productivity of these watersheds and the species they support.
