Invasive Species

Every year non-native species are introduced into the United States through accidental import.  Many of these species such as Argentine ants, Fire ants, Rasberry Crazy Ants and Hydrilla become an invasive nuisance causing destruction for homeowners, ranchers, farmers and natural ecosystems.  The following list includes invasive species that can accidentally be transported through camping equipment, watercraft and plants.  You can help stop the spread by becoming aware of potential invasive species and by taking steps to ensure you don’t transport any with you.
