Sustainability in Action
Helping to eradicate invasive plants is an important aspect of practicing sustainable forestry
Sounding less like plants and more like a lineup of Harry Potter's opponents, invasive species such as knapweed, ragwort, toadflax, hawkweed and cinquefoil are threatening ecosystems in several western states and provinces.
Especially vulnerable are British Columbia's interior grasslands and dry forests, where the invaders can harm native conifers, erode precious soil, consume critical water resources, increase wildfire hazards, and destroy natural habitat required by wildlife.
Most unwelcome is the deceptive tansy ragwort with its happy yellow blooms. Nicknamed "Stinking Willie," this plant is highly toxic to the animals that eat it. Also prevalent is the puncture vine (pictured), so called because its thorns are capable of piercing bicycle tires.
"With some of the highest numbers of invasive plants identified in the province, the risk to our Okanagan Falls operating area is high," says Brian Drobe, one of our planning foresters, "Uncontrolled, these species can alter the structure and function of the natural ecosystem, causing potentially irreversible damage."
To prevent the introduction and spread of invasive species we seed new-road cut-and-fill sloped with certified “weed-free” grass mixes. In 2011, a $50,000 conservation grant awarded to The Nature Trust of British Columbia by the Sustainable Forestry Initiative (SFI). We are participating in the project by:
- Identifying high-priority locations where invasive plants pose a threat to biodiversity;
- Finding which seed mix best competes with invasive species in order to reduce the threat;
- Learning if grass seeding is enhanced in combination with herbicides and/or fertilizers; and.
- Communicating results to government agencies and other stakeholders.
The three-year study is taking place on 5,000 hectares of SFI-certified forestland that we manage in the Okanagan valley. Along with The Nature Trust, partners include the South Okanagan-Similkameen Invasive Plant Society and the B.C. Ministry of Forests, Lands, and Natural Resource Operations.
