If the salmon do return to Bowker Creek, can they survive in a riparian ecosystem with Mallard Ducks?
Salmon need pristine water to live in Bowker Creek. If we want the salmon to return, then Bowker Creek shouldn't remain as a drainage system. Because the run-off of human chemicals can harm the salmon.
Here is a video clip of a Mallard duck feeding on salmon eggs in a spawning pool. The salmon then proceeds to attack the duck, defending its young.
Here is National Geographic's Video about Salmon and their salmon run.

Mallard ducks eat small crustaceans, grasses, and weeds. Ducks will also eat small sticklebacks and fish eggs, which is bad for salmon.
