Guest speaker, Vicki Simkovic, Coordinator at the Ontario Invasive Plant Council (OIPC), will present this talk on invasive plants. Phragmites, Garlic Mustard, Dog-strangling Vine, and Buckthorn are familiar examples of Ontario's 400-plus invasive species. They crowd out native terrestrial and aquatic plants, altering the environment for insects, birds, reptiles and mammals.
