What far-reaching ecological subsidy do decomposing Pacific salmon carcasses provide to coastal forests?

Answer

Up to 80% of the nitrogen in some coastal forests.

When salmon die after spawning, their nutrient-rich carcasses decompose along the riparian zone, providing an ecological subsidy; studies suggest up to 80% of the nitrogen fueling local flora growth in some coastal forests is derived from these remains.
