Yellowstone National Park has announced that felt sole boots and waders are banned in all park waters.
“Aquatic invasive species (AIS) could have devastating ecological, economic, and recreational impacts on Yellowstone National Park. They are costly to manage and extremely difficult to eradicate. Due to the urgent need to prevent these destructive species from entering the park, felt sole waders and boots worn by anglers will be banned permanently starting in 2018. The park will also implement a new boating season.” – National Park Service
