What organisms benefit from salmon?
Salmon support populations of eagles, gulls, sea birds and more by providing them with nutrients essential for overwinter survival and migrations. The amount of salmon in a stream has been shown to be an indicator of the density and diversity in species of birds in the surrounding ecosystem (Field and Reynolds 2012).
What role does salmon play in the environment?
Salmon are the biological foundation of river ecosystems

What would happen without salmon?
The salmon decline affects biotic factors because they bring MDN that are essential for animal and plant growth. If the salmon population is wiped out then the amount of growth of both the plants and animals will decline as well. This will cause there to be less animals and plants in the ecosystem.
Why is salmon so popular?

Why do trees need salmon?
As the bodies of spawning salmon break down, nitrogen, phosphorus and other nutrients become available to streamside vegetation. According to Robert Naiman of the University of Washington, streamside vegetation gets just under 25 percent of its nitrogen from salmon.
How do salmon help trees?
Building forests
Rich in nitrogen from the sea, the rotting salmon flesh fertilizes forest growth. Salmon promote forest health. Giant trees require nitrogen to grow massive canopies that shade the streams and absorb excessive rainfall. These help prevent flash-floods and mudslides from wiping out salmon-filled creeks.
How do salmon help forests?
Feeding the Forest
Incoming salmon keep forest soils fertile. Due to gravity and erosion, forests continuously lose soil and nutrients to the water. Migrating salmon reverse this process by eating fish and krill at sea and bringing nutrient-rich body mass back into the forest.
Do wolves eat salmon?

What are baby fish called?
