There are 3000 species of native plants in BC. Compared to that, there are only 175 recorded invasive plants in the province. However, having a low number of species doesn't mean there are low numbers of plants. Invasive species have an overwhelming amount of each species, which is why there are so many of them.

Many Parts of Bowker Creek’s water quality are preferable to salmon, such as temperature, pH and dissolved oxygen. It’s nitrogen and phosphate levels should be lowered, but the problem comes with ammonia - a toxic substance bowker creek has too much of. Here is a document detailing the preferred water quality levels for coho salmon.

In order to lay her eggs (called roe), the female salmon uses her caudal fin to dig a shalow hole in the bottom gravel (a redd) to create a low-pressure zone where her eggs can incubate. The female covers the eggs by disturbing the gravel at the upstream edge of her redds. She may make seven redds for her ~5000 eggs.

Our final plan to restore Bowker Creek's salmon is based around restoration: restoring the watershed, changing the flow of the river, creating suitable gravel, providing salmon food, reducing levels of ammonia, daylighitng parts of the creek, and reducing turbidity. While a huge project, it would result in bringing salmon back to Bowker Creek.

In 2011, Spanish banks took on a project restoring its salmon run. The stream had become blocked, and parts were hidden underground. but after clearing the dams, daylighting parts, and restoring natural vegetation, the salmon returned. The story is similar to Bowker Creek - urban devlopement hurt the salmon run, but shows that it can be fixed.

We have concluded that Coho salmon are the ideal species to inhabit a restored Bowker Creek. They were one of the only salmon species present in early Bowker Creek, a high water flow tolerance means that they would be adapted to Bowker's high flow. Coho salmon are endangered, so reestablishing this salmon run may also save the Coho salmon species.

Coho salmon is the salmon species that we have decided would be a perfect fit to restore the Bowker Creek salmon run. Coho salmon are native to the west coast and are one of the original species that was historically part of the salmon run through Bowker Creek. Here is an image of a Coho salmon and how to identify the native fish.
