Here are some ways to identify a healthy riparian zone, like the one pictured: When there aren't patches of open soil, it indicates the riparian zone's plant life is well-established and healthy. If uncovered, then the soil shouldn't be sandy. The banks of the zone's stream should also avoid erosion, while trees should vary in size and in age.    

Riparian means that something is related to wetland. This can apply to being on or near riverbanks or other freshwater sources. Because of this, the specific sort of plants found on or adjacent to streams or creeks could be described as "riparian".

Here you can view a time lapse of the Bowker Creek reconstruction at Oak Bay High School.

Before: -natural water channel/flow -surrounded by wetland -many fish/ wildlife -First Nations derived food and fresh water from the stream -nutrients transported from the creek, supported Oak Bay's rich ecosystem Currently: -urban development and agriculture expanded -stream channel was straightened, excavated, and enclosed in pipes -lowered water levels

It's very important to maintain a natural Bowker Creek. There are many easy ways to do our part, for starters, we would have to carefully watch the growth of invasive plants. We should also watch the pH levels of the water, and not use fertilizers in our gardens, to prevent toxic runoff. Also, spreading awareness can go a long way for the creek.
