Invasive species are non-native plants and animals that adversely affect the natural balance and beauty of the landscape, from our natural areas, lakes and trails to your own backyard. They can impact your ability to enjoy many outdoor activities, including hiking, fishing and gardening.

Once established, they are very difficult and costly to manage, control and remove.

  • Use nosebags when feeding pellets and grains, they reduce waste and eliminate ground “seeding”, and aid in disposing of any weed seeds that remained in the feed.
