WHAT IS THE PROBLEM WITH INVASIVE PLANTS?
Most problematic invasive plants — or weeds — found in North America were transported here from other continents. When invasive plants like Canada Thistle (which is native to Europe) become established, they often spread to dominate the native vegetation. By altering plant communities, invasive plants can lead to changes in:
- habitat and food opportunities for wildlife
- abundance and quality of agricultural lands and livestock forage
- soil and water quality
- ecosystem processes and species biodiversity
- visual quality and aesthetic value of the landscape
