Salmon die after spawning due to exhaustion and malnutrition. As most salmon are sea fish, the environment of the creeks and streams are poisonous to them and they are unable to feed as they swim up stream. By the time they get to the spawning grounds they have used up their stores of energy and cannot get back to the sea.

The dead Pacific Salmon are fed upon by forest animals, such as bears, accounting for nearly 80% of their weight gain before Winter. Any that are missed get washed into the forests during peak high water periods, transferring nutrients collected from the oceans to the forests.
