Invasive Plant Lists

There are three basic types of invasive plants found in Canada. These are: Trees, Shrubs/Vines, and Herbaceous species (includes Wetland species). These species flourish in a diverse number of habitats, ranging all across Canada. The majority of exotic species found in Canada are European and Eurasian in origin. Many of these species share the same characteristics, such as rapid growth in a variety of conditions, abundant seed production, highly successful seed dispersal, germination, and colonization, the ability to propagate vegetatively, a lack of pests or pathogens acting as natural controls, the ability to out-compete native species, and a high cost to remove and control.

Each species on the list is provided with information including: 

Species Name - scientific name of the species 

Common Name(s) - name(s) given to the species 

Origin - continent of origin for the species 

Status - whether or not the species is commercially available (in seed or vegetative form) 

Provincial Location(s) - where in Canada the species can be found 

Plant type - whether the species is a Tree, Shrub/Vine, or Herbaceous species 

Habitat - the habitats in which the species can be found 

Invasive Potential - whether the species is considered to be 

                            L = low level invasive 
                            P = potentially invasive 
                            H = highly invasive 

Description - information on the height, flower, leaves and stems, and fruit produced by the invasive species 

Control Methods - methods that can be used for the removal of small scale invasions of the species 

Usage - current or past usage of the species by humans
