What is an Invasive Species?​

Invasive species reproduce and spread quickly. They can thrive in a broad range of habitat conditions, and can often out-compete other species. This species invades and blocks native plants from growing. Invasive species are spread by human and animal transporting, crops and escaping garden plants. These non-native species may have no native predators to help decrease their spread.Photo of Emerald Ash Borer on tree branch

An invasive species found in Aurora is the Emerald Ash Borer, an invasive insect that kills all types of healthy ash trees. The Emerald Ash Borer poses no risk to humans; however it is a major threat to our Town's forests.

Giant Hogweed, found alongside roads, streams and in open spaces. Similar to the Wild Parsnip, the sap from this plant can cause severe blisters, burns, and scars. The effects of this plant are further intensified when exposed to sunlight. If contact occurs with eyes it may cause loss of vision.

 Residents can help control the spread of invasive non-native species by becoming aware of them and acting to limit their spread. Avoid the transportation of firewood or live bait while travelling or boating. Clean all equipment thoroughly to remove seeds, leaves, and mud. Use Native plants in gardens and landscaping.  To find out which plants are safe to use check out this   'grow me instead' guide from the Ontario's Invading Species Awareness Program Website, as well as the Landowners Guide to Managing & Controlling Invasive Plants.

Other invasive species found in the Town of Aurora are European Common Red, Japanese Knotweed and Dog-Strangling Vine. These three invasive species are regulated as a restricted species under the Ontario Invasive Species Act, 2015.
