Invasive Plant Removal

Plants and animals that have been introduced from other parts of the world into new habitats have the potential to become “invasive,” meaning that they thrive without the control of natural predators that otherwise keep their populations in check with the ecosystem. As a result, they often out-compete native species in the areas where they are introduced. In Stoney Creek the following species are present:

  • English Ivy (Hedera helix)
  • Himalayan Blackberry (Rubus discolor)
  • Japanese Knotweed (Polygonum spp.-Fallopia Japonica)
  • Yellow Archangel (Lamiastrum galeobdolon)
  • Periwinkle (Vinca minor)
  • Policeman’s helmet (Impatiens glandulifera)

Invasive plants on riparian slopes can spread downstream. But, whilst unwanted, they can also keep sediment from eording into the water.

What you can expect to see and hear

Volunteers are assigned work areas and given specific invasive plants to target; information is provided on what these plants look like and how to remove them safely and without damaging any surrounding native species. The ‘invasives’ are loaded into large paper bags and arrangements are made for City pick-up.





Usually in spring/summer
