Salmon provide nutrients to Alaskan streambanks

Read the full story from the American Society of Agronomy.

Adult Pacific salmon spend a great portion of their life in the ocean. But their life began along the banks of freshwater streams. Their life will end there, as well. These important steps in the lifecycle of salmon play a role in the health of streambank ecosystems.

David D’Amore and a team of scientists studied how different soils respond to the delivery of “salmon-derived nutrients.” These nutrients come from adult salmon returning to their home streams, known as spawning. The study sites were forested ecosystems in Alaska’s coastal temperate rainforest.
