The month of May has been proclaimed “Invasive Species Action Month” by the Province of BC. Noxious weeds and invasive alien plants are non-native species that have found their way into BC, including our fine city. Without the insect predators or plant pathogens that naturally control them in their native habitats, noxious weeds and plants can quickly spread out of control and pose health, ecological, and economic impacts.
- cause skin irritation, trigger allergies, and be unpalatable or even poisonous to animals
- clog waterways; kill native trees; and out-compete crops, ornamentals, and native plants
- be costly to control as they may result in a need to replant crops and restore or reclaim native ecosystems
Identified noxious weeds that are having a negative impact in Kamloops are: Japanese Knotweed, Yellow Flag Iris, Hoary Alyssum, Dalmatian Toadflax, Leafy Spurge, Sulphur Cinquefoil, Orange Hawkweed, Hoary Cress, Common Tansy, Oxeye Daisy, and Knapweed. Many invasive plants have a beautiful appearance, were initially introduced as ornamentals and some still are intentionally planted.
