How can watercraft owners help prevent the spread of AIS?

Cleaning and drying watercraft after use is a highly effective method for preventing the spread of aquatic invasive species (AIS). When watercraft are pulled out of the water, they may carry organisms on their hulls, in their motors, or within compartments. By thoroughly cleaning and drying the entire watercraft, owners help remove any potential hitchhiking species before the boat enters another body of water. This practice eliminates the risk of transporting these species across different ecosystems, which can lead to significant environmental damage and economic costs.

The other options provide insufficient methods for preventing AIS spread. Not using watercraft at all would certainly prevent direct transport but isn't practical for those who wish to enjoy recreational boating. Using watercraft solely on one body of water may limit exposure in theory, but it doesn't address the risk of inadvertently transferring species when the watercraft is not properly cleaned. Storing watercraft in wetlands could actually increase the chance of AIS spread, as wetlands may harbor many invasive species that could easily latch onto the storage area and then be transferred elsewhere. Overall, cleaning and drying watercraft post-use is a practical and effective strategy in combating the spread of AIS.
