As spring arrives and more people tend to their gardens, Ontarians may begin to notice more non-native creatures and plants.
“Ontario has the largest number of invasive species in Canada — more than 180 aquatic invasive species, at least 39 forest insects, 10 tree diseases, and around 500 non-native plants, with more added every year,” said Karen McDonald, the Toronto and Region Conservation Authority’s senior manager of restoration and infrastructure.
