Ecosystem Connections in the Pacific Northwest

In the Pacific Northwest, salmon play a crucial role in transferring ocean nutrients to river ecosystems. These nutrients, carried by salmon bodies, fertilize trees when salmon carcasses are left on stream banks. This process highlights the hidden connections within ecosystems and the impact of human actions. By understanding these connections, we can see how small, positive actions can help restore and restitch the webs of life by reintroducing key species.

Why do trees in the Pacific Northwest need salmon?

• Salmon provide shade for the trees.

• Salmon protect trees from pests.

• Salmon help in pollination.

• Salmon bodies bring nutrients from the ocean.

How do nutrients from salmon reach the trees?

• Via carnivores leaving salmon carcasses on stream banks.

• Through the air as salmon decompose.

• By being absorbed directly from the river water.

• Through the roots of the trees.

What can tracing nutrients from the ocean to trees teach us?

• The migration patterns of salmon.

• The hidden connections in ecosystems.

• The importance of ocean currents.

• The growth rate of trees.

What is the impact of human actions on ecosystems?

• They always lead to positive outcomes.

• They can only cause harm.

• They can be both damaging and restorative.

• They have no significant impact.

How can ecosystems be restored?

• By cutting down trees.

• By introducing certain key species.

• By removing all carnivores.

• By stopping all human activities.
