Habitat destruction or alteration
Human impacts to salmon habitat
through urbanization have had a devastating effect on
salmon. For instance, between 96% and 99% of the wetlands
in the Duwamish
estuary
have been destroyed by development. Estuaries, where freshwater meets
saltwater, are essential
salmon habitat. Urbanization also affects water quality and alters
water flow in streams, harming
spawning grounds and eroding streambanks. (6 of 15)
