The restored Bowker Creek area is an asset to Oak Bay High school, in that it includes a beautiful outdoor classroom and easily accessible ecosystem to study.

Native plants provides habitat, food and survival needs to humans, animals, and plants. They use less resources, and store bigger amounts of carbon therefore creating better air quality. Native aquatic plants protect aquatic wildlife, and come as a source of food. They also drive invasive species away.salal

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.dandilion

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.
