Dangers of Invasive Plants
Invasive species are primarily introduced by human activity and originate from across the globe. They pose a significant threat to ecosystems and crops by competing for light, water and nutrients, introducing disease and pests, and even altering soil composition in a way that harms native species.
Identification and Prevention Tips
Prevention is the first line of defence against these pesky plants, so keep an eye on new weeds growing in your fields and around your property. Early detection makes them much easier to control. Once they become established, it’s incredibly difficult to get rid of them!
The Quebec Ministry of the Environment provides an online tool named Sentinelle (French only) to help you identify over 65 invasive plant species. This database contains descriptions of their main features as well as photographs, and you can even use it to report your observations.
If you believe you have found a problematic plant, take a photo and indicate its location, then submit your report. Experts will analyze this data and import it into Sentinelle. Being vigilant and getting the community involved is the only way we can protect our farmland and natural environments.
Want to add a few more species to your mental checklist? Think of giant hogweed, alder buckthorn and Eurasian water-milfoil—they make great words for Scrabble too!
