Invasive plants are non-native plants that have been introduced into our environment that adversely affect local habitat. Many invasive plants have been introduced to British Columbia without their natural predators and pathogens that would otherwise keep their populations in check.
Invasive plants can have negative impacts on:
- Lower property value
- Increase landscape management costs in parks and natural areas
- Cause property and infrastructure damage
- Crowd out native plants
- Effect soil fertility and disturbance
- Disturb ecosystem balance
- Destroy wildlife habitat
- Reduce soil stability & water quality
- Endanger humans, pets, livestock and wildlife
- Reduce aesthetics of an enjoyable landscape
- Reduce functional use of outdoor space
Top Invasive Plants:
Giant Hogweed is an invasive plant and it can pose a serious threat to human health and natural ecosystems. The sap of Giant Hogweed causes phytophotodermatitis in humans, which can result in burns and blisters. Giant Hogweed has been observed in Port Coquitlam and the City wants to ensure it does not become a widespread community concern.
