This is a handout from our webinar, "Controlling Canada’s ‘Worst’ Invasive Plant Species". Phragmites is an invasive plant species that was introduced in Canada in the early 1900s. It can establish easily, spread quickly, and fundamentally alter wetland ecosystems. The species threatens 1 in 4 species at risk in Ontario and has economic and societal impacts. Biocontrol has the potential to disrupt competitive dynamics between invasive and native plants, allowing for plant community recovery.
In 2005, invasive Phragmites australis was called Canada’s “worst” invasive plant species. Since then, invasive Phragmites australis has spread to every Canadian province and continues to threaten wetland biodiversity and integrity. Biological control is an emerging tool to suppress invasive Phragmites australis. Claire’s research, with collaborators at the University of Toronto and Agriculture and Agri-Food Canada, focuses on the efficacy of a new technique for invasive Phragmites australis control and monitoring the recovery of native plant communities. Learn more about the two moth species that feed on invasive Phragmites australis and the promising results for Phragmites australis biological control she has found so far.
