Naturalist Bob Armstrong observed the salmon spawning in the Eagle River outside of Juneau, Alaska. The fish return to their freshwater streams to mate and die, providing nutrients to the forest and soil.

Scientists have documented how these nutrients help the forest grow, with isotopes tracing the path from fish to spruce trees. Commercial fisherman Lindsey Bloom noted that salmon are essential for food security in rural Alaskan communities, particularly those not connected to a road system. While climate change and marine heat waves have impacted salmon runs in some rivers, melting glaciers may create new habitats. Bloom stated that salmon are an essential part of Alaska, providing sustenance and connecting the people to the environment. The salmon life cycle is described as a biological conveyor belt where the fish fertilize the forest with their decaying bodies.
