Ecological restoration of natural woodland and meadow sites invaded by dog-strangling vine (Vincetoxicum rossicum) in southern Ontario.

Dog-strangling vine is one of the most invasive plants in eastern Canada. Previous attempts to control the spread of the vine have been unsuccessful. Recent research on this invader suggests that when it invades an area, it perturbs soil microbial communities. These perturbations appear to interfere with some native plants’ ability to grow. However, other native plants appear to be resistant to these soil alterations. This work aims to identify additional plant species that are resistant to the soil effects of dog-strangling vine, to determine how long these soil effects last, and to identify soil amendments that can reduce the impact of invasion. This research will help develop much-needed management and restoration strategies and will help protect and revitalize the fragile ecosystems that dog-strangling vine currently threatens across eastern Canada.
