Canada has released the first ever biological control agent to tackle invasive common tansy (Tanacetum vulgare), an invasive plant that negatively impacts the country and wider region’s livestock, rangeland, and native biodiversity. The release of the agent – a stem-mining weevil called Microplontus millefolii – marks a major milestone in efforts to manage this invasive plant across North America, reducing its ecological and economic impacts. In partnership with the British Columbia Ministry of Forests, Agriculture and Agri-Food Canada (AAFC) conducted the first releases of 1,200 adult weevils in May. AAFC conducted a further release of 400 weevils in Alberta in June. …These releases target areas experiencing significant, negative impacts on agriculture and biodiversity. …The common tansy has diminished the health of lands used for livestock foraging, as well as displaced native vegetation, and has hindered forest regeneration following logging. …Over 10,000ha of common tansy has been recorded in BC across all climate zones said BC’s Janine Brooke.
