Over the years we have altered the Salmon's natural habitat. It is no longer a natural creek. We have manipulated every twist and turn of the creek and now it is not a natural or sustainable environment for Salmon. In south Oak Bay, we have essentially created a big drainage ditch with the giant cement wall lining the creek.

Bowker Creek’s gravel doesn't meet salmon spawning requirements (read pdf) The surface has large stones that would be difficult to move and an underlayer that is fine and densely packed. To make the gravel bottom suitable for roe, about 8 cm of new gravel would need to be added to the creek’s floor to meet coho spawning criteria.

The 100-year vision for Bowker Creek’s layout shows an almost completely daylighted creek going as far as Mackenzie Road and would be suitable for supporting the travel of salmon from the ocean, The creek’s design will also benefit the water quality and turbidity, making it the first crucial step to making Bowker Creek a salmon-friendly habitat.

This is a diagram of a salmon's life cycle. Salmon are anadromous meaning they hatch in fresh water, migrate to the ocean, then return to the freshwater to reproduce. The creek would act as a habitat for spawning and unmatured salmon, meaning that Bowker Creek would have to meet several criteria in order to be habitable for salmon alevin and fry.

what exactly are we talking about? our driving question is "How do native plants effect the ecosystem?" Why are they so important to not only us but to many animals too? why do we depend on them so heavily, and what benefits do they give to the whole ecosystem as a whole?
