Noxious weeds are non-native plant species that are difficult to control. In the absence of their natural predators and diseases, these weeds aggressively compete with native plants for water and nutrients, threatening the health of natural and economic resources and the industries that they support.
The Southern Interior Weed Management Committee (SIWMC) is a registered charity comprised of volunteer members representing private & public agencies, clubs and organizations in the Thompson-Nicola Region of British Columbia. Members of the society are dedicated to increasing awareness of invasive plants and associated losses caused to the natural and domestic resources of our region.
If you find an invasive weed here is the place to let someone know.. Report-A Weed ... or you can tell us through our contact us tab above.

'Knapweed is highly competitive and capable of invading grassland sites to the exclusion of native vegetation. Domestic animals and wildlife, such as elk, rely on these range grasses and herbs for up to 80 percent of their diet. Knapweed encroachment can destroy the forage base and would result in a significant decline in deer and elk numbers. Over 40,000 hectares in BC are knapweed infested, reducing forage potential by up to 90 percent.'
