Get Involved

  • Remove plants, seeds, animals, and mud from boots, pets, gear, and vehicles before and after exploring.
  • Check all your gear. Non-native seeds can stick to the bottom of your pack, the cuffs of your pants, or your animal’s fur.
  • Stay on designated trails and roads to reduce disturbance and minimize contact with invasive plants. Do not camp or travel through areas infested with invasive plants.
  • Do not release unwanted pets or dump the contents of an unwanted aquarium into the wild. In most states it is illegal.
  • Use certified or local firewood and hay.
  • Stop aquatic hitchhikers! Clean and drain your boat and gear before leaving a site.
  • Keep the adventure and leave the invasive species. PlayCleanGo!
