Learn to identify invasive plants!
In June, we encouraged everyone to explore biodiversity, and we shared some facts about native plants. Now, learn about what you don’t want to see in gardens and natural areas- invasive species!
Invasive plants are undesirable because they put local biodiversity at risk, negatively affecting native plants, wildlife, and their habitats. They do so by out competing native plants and altering natural areas because:
- They are usually the first plants growing leaves after the winter and the last plants with green leaves in the fall.
- They can thrive in poor or dry soil.
- They can grow faster than other plants, which means they can get more sunlight and nutrients.
- They spread very quickly and easily.
As a result, it is important to control their spread as much as possible. They also interfere with agriculture and forest regeneration, and often force costly restoration efforts due to their rapid spread (for more information, check out Ontario Invasive Plant Council).

Did you know that despite its name, Canada Thistle is actually from Europe? Or that Garlic Mustard is considered one of Ontario’s most aggressive forest invaders, displacing native wildflowers like trilliums? This month, follow along on Twitter and Facebook to learn about invasive plants that can be found in gardens, neighbourhoods, and natural areas. We’ll share some facts and photos of common ones like Canada Thistle, Garlic Mustard, and Common Buckthorn (see photos below), which we have come across in our Wildflower and Medicine Wheel gardens at the Trafalgar campus.

You can also help track these species so that the province can control their spread and be aware of where they have been spotted at EDDMapS Ontario– Early Detection and Distribution Mapping System.
It is important that we maintain biodiversity so that local ecosystems can continue to thrive and contribute to the wellbeing of humans and the planet. Ensuring we remove invasive plants can help native plants thrive and support important processes, like attracting pollinators (who work hard to fertilize our food), which contributes to earth’s natural processes!
