Grant helps the Nature Trust of BC

Solutions sought to threat posed by 56 invasive plant species on public lands

The Nature Trust of British Columbia has been awarded a Sustainable Forestry Initiative® (SFI®) conservation grant to find the most effective way to reduce the spread of invasive plants in vulnerable ecosystems in British Columbia’s southern interior.

The project will receive a total of $50,000 over three years through the SFI Conservation and Community Partnerships Grant Program. In addition to The Nature Trust of British Columbia, partners include Weyerhaeuser Co. Ltd., South Okanagan-Similkameen Invasive Plant Society and the British Columbia Ministry of Forests, Lands and Natural Resource Operations.

“More than 200,000 hectares (500,000 acres) of publicly owned grassland and open forest in British Columbia have been infested with 56 different invasive plants and noxious weed species,” Carl MacNaughton, conservation land manager for the Nature Trust of British Columbia, said today. “The SFI grant means we can identify and map priority locations, then test grass seed mixes and management techniques to learn how best to reduce invasive plants to a level where they are no longer an environmental threat.”

Alien invasive species such as tansy ragwort and spotted knapweed are a significant threat to biodiversity in British Columbia, especially in the province’s interior grasslands and dry forests. They can affect the survival and growth of planted conifers; accelerate soil erosion and stream sedimentation; consume critical water resources and negatively impact water quality; increase the wildfire hazard; interfere with regeneration of forests; and destroy or otherwise alter critical natural habitats required by species at risk or other high valued wildlife.

The project will take place on about 5,000 hectares (12,000 acres) of SFI-certified forested lands managed by Weyerhaeuser in south-central British Columbia. The operating area includes important wintering grounds for ungulates such as elk and mountain goats; fish-sensitive and community watersheds; and habitat for seven federally-listed species at risk – all of which are potentially at-risk of impact from invasive species.


“SFI certification contributes to the conservation of biological diversity, the protection of critically imperiled and imperiled species and Forests with Exceptional Conservation Value by requiring that program participants limit the introduction, impact and spread of invasive species,” SFI President and CEO Kathy Abusow said. “This partnership will help companies by pinpointing infestation locations and recommending management options. It will protect native or naturalized species in the Okanagan-Similkameen region – and have broad application throughout dry forests across western North America.”
