Invasive species are species that do not naturally occur in a specific area and whose introduction does or is likely to cause economic or environmental harm or harm to human health. Invasive species are often very hardy, reproduce and spread quickly, and are quite difficult to kill or remove. They spread and take over areas from the natural species. This limits the food source of native animals, as many do not eat these invasive plants. Invasive species are one of the greatest threats to biodiversity world-wide. 

Vancouver Island is a gateway to the province and has many networks that invasives can travel through. People can purposefully transfer invasive species, such as Scotch Broom, which was brought from Scotland in the 1850s as a garden ornamental. Invasives can also be introduced unintentionally through boats, vehicles, and by wood being washed ashore from other countries. They spread through natural reproduction and seed transfers, but are also commonly spread through people dumping garden waste or planting them in their gardens due to their aesthetic appeal. Beware- they spread fast and once they take over your garden they will not look so pretty!
