Three-Spined Sticklebacks possess the ability to evolve remarkably quickly. Their species is a master at adaptive radiation, producing over ten new variations in less than 20,000 years - a mere blink of an eye in the ordinary evolution timeline. These fish frequently interbreed, producing stable and healthy offspring, ready to foster new species.

Sword ferns have multiple adaptations to help them survive in their natural habitat. Instead of having trunks, sword ferns have rhizomes - flexible branch-like appendages that hold their fronds. These ferns also have spores, which are housed on the underside of each frond. These spores can travel for miles in the wind and are released in billions.

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.
