Terrestrial Invasive species - Non-regulated animals

Terrestrial invasives come in many forms including plants, animals, insects, fungi and diseases. They affect the health of our forests, prairies, parks, urban landscapes and more. When these landscapes are unhealthy, all the benefits they provide to us are at risk. The good news is, each one of us can make a difference. Learn what to look for, and you can help slow the spread of invasive species!
