The perfect habitat for salmon is plants that run along the water’s edge, and overhanging branches to keep them cool. As well as debris and fallen trees to boost the intricacy of the water channel. Wood, rocks, pools, riffles, as well as clean gravel for spawning are all key to having the perfect habitat for salmon.

Prior the areas around Bowker creek being urbanized it was very different. Bowker creek was more biodiverse, and was covered in plant life. It also flowed more naturally without concrete barriers along side it. There was also not any nearby roads, or any harmful activity near the creek. Overall, Bowker creek was completely natural and had was reliant on carrying and disposing water around Victoria.

Salmon eat plankton, insects, and larval invertebrates when in fresh water. But when they are in the ocean, the feed on small fish. When salmon are in the ocean they still need a balance of their common diet species.

I don't think that the restoration contributes to bringing salmon back. This is because the way we are redesigning the creek does not resemble the habitat and living conditions salmon need. The creek is too fast, shallow, and dirty. It also does not have enough pools for spawning.

Salmon require much cleaner water that is present in Bowker creek. The storm drain runoff isn't just too dirty it also isn't deep enough for salmon to live in. Runoff from storm drains can contain nitrogen and phosphorus pollutants from fertilizers and yard waste. Which will drastically affect the salmon habitat.

Some predators at Bowker creek that may affect salmon life is seagulls. Seagulls are not very common predators towards salmon, but will eat salmon eggs. Salmons skin is very tough, making it difficult for seagulls to eat them. Eagles are also a threat towards possible salmon life at Bowker Creek.

I do not think salmon will have a major impact on the existing animal life in Bowker Creek. There are not any other animals that have a similar diet as salmon. Salmon may be a disturbance to the ducks. But I do not think there would be a significant difference.
