Invasive Plants

Invasive plants can spread across the forest floor, choking out native species and altering ecosystem dynamics.

To learn about the threat of invasive plants, watch the following informational webinar! In this presentation, Rachel Gagnon, coordinator with the Ontario Invasive Plant Council, discusses garlic mustard, dog-strangling vine, invasive honeysuckles, Japanese knotweed, and common buckthorn. Learn how to take action and control the spread of these invasive forest plants. 



Prevent the spread of invasive plants!

Invasive plants can be mistakenly introduced into natural environments by escaping gardens and backyards. Once planted in a garden, seeds from invasive plants can disperse to nearby forests and woodlots. In addition, improper disposal of garden waste can introduce the roots and seeds of invasive species directly into nature. If the environment is suitable, these plants can become established in the natural landscape, and outcompete native species. 

Help prevent the spread and introduction of invasive plants by planting native species in your garden! 

Developed by the Ontario Invasive Plant Council, the Grow Me Instead guides identify potentially invasive garden plants and promote suitable alternatives that are either native or non-invasive.  You can download copies of the booklets below:

Best Management Practices (BMP's)

With appropriate action, many species of invasive plants can be effectively managed and controlled. For BMPs on a number of invasive plants, including common buckthorn, giant hogweed, phragmites, dog-strangling vine, and more, visit the Ontario Invasive Plant Council's Best Management Practices Library.
