Gorse
Gorse (Ulex europaeus) is a highly invasive shrub that has become a significant concern in parts of British Columbia (BC), especially on Vancouver Island and parts of the south coast.
Field Scabious
Field scabious crowds out forage and pasture plants, reducing food availability for grazing animals. It grows along disturbed roadsides throughout the province. It is an escaped ornamental popular for its pretty flower and ability to attract butterflies from its native range of Europe and Asia.
English Ivy
English ivy (Hedera helix), a non-native, invasive evergreen vine, is a significant problem in southwestern British Columbia, particularly on Vancouver Island and the Lower Mainland, where it can smother native plants and damage trees.
English Holly
Its shade tolerance has allowed English holly to invade much of the south coast region of British Columbia, in the Fraser Valley and on Vancouver Island.
Diffuse Knapweed
Diffuse knapweed, an invasive plant, is a problem in British Columbia, particularly in the southern interior, where it can cause significant economic and environmental damage by outcompeting native vegetation.
