Natural Production Restoration Project

Dramatic declines in the abundance of anadromous Pacific salmonids have occurred over the last century in the Columbia River basin.  Population declines followed harvest, hydrosystem and watershed development, habitat loss and degradation, and reduced survival in freshwater, estuary, and marine environments. These declines are accompanied by greatly reduced levels of natural production due to an array of anthropogenic factors.
