Salmon are considered a keystone species, meaning that their presence (or absence) is central to many other physical, chemical, and biological processes in an ecosystem. If salmon populations are healthy, it can generally be assumed that watershed conditions and functions are healthy.
The Portland Watershed Management Plan directs the City to “implement watershed actions to maximize the persistence of native Willamette and Columbia River fish and other aquatic organisms and assist with species recovery and potential population productivity by protecting and improving hydrology, habitat, and water quality.”
