A healthy habitat can benefit wildlife by there being no pollutants that could potentially be fatal. Even if it is very healthy it can have a negative impact. If there is a build up of nitrogen or phosphorus there can be a algae bloom which block natural light from getting in.
Bowker Creek has been artificially deepend/ straightened with cement and rock. Due to this, Bowker Creek has been separated from its floodplain and destroyed. Leading to, the floodplain has been converted to urban land and the creek has increased flow speed, resulting in erosion. No riparian zones are left and excess water isn't soaked up.
Unfortunately, Bowker Creek suffers from many environmental concerns, here are some of the main ones, which will been gone into further detail in the next entries:
If you have ever walked along Bowker Creek, or even just around Oak Bay, you will notice many blackberries. There are so many in fact that they are smothering the native plants. These invasive plants block out the light for native plants, causing many of them to die. Although these berries are delectable, and are very nutritional, they are interfering with biodiversity at the creek.
Many native plant medicines have been found that can treat some common colds, viruses, fevers, and even diabetes. One study counted almost 550 plants that could be used medically that some Canadian First Nations used - The plants cured close to 30 different sicknesses. Sadly the passed down knowledge of these plants is disappearing because less people are relying on the teachings to survive.
Natural plant dyes have been around for hundreds of years, and have been very helpful to many First Nations communities in Canada with dyeing clothing. There are dyes for each different colour made from a variety of trees, flowers, barks, leaves, and berries.
Deathcaps are one of the deadliest mushrooms in the world, and you can find them in Victoria. I have yet to see one at Bowker Creek but trust me, they are around. So if you do decide to go foraging, make sure you can identify mushrooms properly and always double check your finds. Linked here is a short video about deathcaps and a brief explanation on how to identify them.
Here is a small paper I wrote about coprinoid mushrooms, and how to identify different species you find around Victoria.
