The big leaf maple is the tallest maple in Canada, specially adapted to life in the forest. It’s narrow crown is supported by a large, branchless stem, ensuring it stays upright during the Canadian winter. It’s seeds are distributed in pairs, each with twin wings that carry them, twisting and turning, down from the canopy and into new territory.

Blackberries are so specialized to invasion, they’ve developed two different ways to spread. The first is by seeds, which are distributed through their fruit. These seeds are eaten by animals, and then return to their environment after being excreted. The second is through runners, which grow at the end of one year and produce a new plant the next.

English ivy is specially adapted to spread throughout their environment. Their roots release a substance that sticks to the surface the ivy wishes to climb, and small suction-like discs grow from the main stem to keep the ivy secure. English ivy’s roots spread sideways instead of up and down, gathering nutrients on the move.

Native thistles like the blessed milk thistle have evolved spines on their leaves and flowers to discourage animals from feeding on them. These plants also produce over 6000 seeds annually, with each flower growing more almost 200! The plants can tolerate high winds and cold temperatures, and are well suited to life in Victoria.

Bowker Creek has always been a great resource for students and citizens to learn and observe, but it hasn't always looked this good.

This is a chart that compares the water quality of Bowker Creek to the water quality necessary for salmon. As your can see in the chart, there is too much nitrate in the water and not enough dissolved oxygen necessary for salmon.
