Invasive plants are an emerging issue across Ontario and pose a significant threat to Ontario’s biodiversity and forest health. In some parts of Ontario invasive species such as garlic mustard, dog-strangling vine and buckthorn are totally dominating the forest floor of many woodlots.

As landowners, our best defence against these invading marauders is knowledge! We need to:
|
|
-
|
Gain a better understanding of the problem; |
|
-
|
Learn to identify the various invasive species that are invading our woodlands; |
|
-
|
Become familiar with the various options available to control and prevent the spread of invasive species; and |
|
-
|
Take action! Remove invasive plants when they first appear. They can be easier to control now than in a year or two. If the population becomes established, the job of removing invasive plants may be more than you can handle.

What is an
Invasive species?
They are non-native plants that have the biological ability and/or lack natural control agents that provide these species with a competitive edge to out compete natural species within our woodlots.

The following landowner guide has been developed is assist landowners.
The Landowners Guide to Controlling Invasive Woodland Plants
The Landowners Guide to Controlling Invasive Woodland Plants is a guide on the ecology and control methods of Ontario's most common terrestrial invasive plants including: dog-strangling vine, garlic mustard, Norway maple, buckthorn, giant hogweed, Japanese knotweed and exotic bush honeysuckles.
Originally written by Dave Pridham as an extension note in 2004, it was revised and updated in 2009 through a partnership between the Ontario Federation of Anglers and Hunters & Ontario Ministry of Natural Resources Invading Species Awareness Program and the Victoria Stewardship Council. Members of the Ontario Invasive Plant Council provided technical assistance and review.
