Aquatic Invasive Species
PREVENT THE SPREAD OF PATHOGENS - CLEAN. DRAIN. DRY.
Aquatic invasive species (AIS), such as whirling disease and zebra or quagga mussels, are a serious ecological and economic threat to the Greater Yellowstone Ecosystem. Boats, waders, and anything else that comes in contact with a body of water has the potential to spread non-native plants, pathogens, and other invasive species among water bodies.
Never empty containers of bait, fish, plants, or animals into park waters.
