Native plants store carbon dioxide better than invasive species. They adapt better to the surrounding environment conditions. Native plants require less resources to survive (such as water and soil)  therefore making it beneficial to the environment. 

The second year was the year of planting all of the native plants we see today. Said plants contribute to the ecosystem in many positive ways.

In Conclusion, as we have seen in many examples of successful stream restorations, more needs to be done to significantly change the ecosystem than just improving the water quality. With improvements in water quality and other aspects we could bring back coho and chum salmon as well as cutthroat salmon back to Bowker creek.

It will take a few years, but it is completely possible to bring back species to the creek. Once there has been a complete clean-up of all water deposits in the creek, there can be further work for species. A controlled spot for spawning salmon would be a great challenge to be able to see salmon run through the creek again.

Besides water quality there is many other factors that influence the ecosystem in bowker creek. In bowker creek some factors that affect the ecosystem are how much of the creek moves through pipes, the faster flow rates at parts of the creek, and pollution density in parts of the creek.
