Invasive species are those that have been introduced into an area where
they are not native, causing significant damage to the natural ecosystem.
The rapid growth of invasive plants competes with native species for vital
resources, such as food and water.
*Native species are the plants that naturally grow in this area.
Invasive species are a significant threat to biodiversity through
habitat loss.
Types of invasives:
English Ivy - An evergreen vine that grows as dense ground cover or
climbs up trees. It suppresses native vegetation, and its smothering can contribute to increased occurrences of blowdowns and disease.
Giant Hogweed - This plant can grow up to 5 metres tall and is identifiable by
its dark green, coarsely toothed, deeply incised leaves, and hairy stems. Giant hogweed produces a highly toxic sap that can cause burns, blisters, and scarring upon contact.
Periwinkle - This groundcover, originally from Europe, became popular in
ornamental gardens for its fast growth and dense coverage.
However, it spread rapidly through BC forests, choking out
native plant species and negatively impacting conifer
seedlings by competing for space and resources.
Lamium - This plant is commonly found in hanging baskets and garden
beds. When it spreads to the forest floor, it can smother
native herbs, shrubs, and even moss, while its dense cover
also suppresses the growth of native tree seedlings.
Holly - The deep roots of this invasive plant compete with native
species for essential nutrients and water, inhibiting the
growth of the surrounding vegetation. Additionally, the
plant's berries are toxic to both humans and pets if ingested
Japanese Knotweed - All species in BC can grow through concrete and asphalt,
damaging infrastructure. Globally, significant habitat has been lost. They are extremely difficult to remove, as they spread through seeds, root, and stem fragments, making
them challenging to control.
What can you do:
- Do not dispose garden waste or soil in parks and greenspaces. It is prohibited and
contributes to the spread of invasive plants. - Stay on designated paths.
- Report invasive species through the report invasives BC app or for local
sightings email parks@comox.ca - Do not grow or buy invasive plants.
