What type of watercraft are commonly inspected to prevent AIS transport?

The focus on high-risk watercraft for inspection is based on the understanding that certain types of boats are more likely to introduce Aquatic Invasive Species (AIS) into new environments due to their use patterns and the ecosystems they navigate. High-risk watercraft typically includes those that are frequently used in varied water bodies, especially those with a history of AIS contamination.

These watercraft may include, but are not limited to, motorized boats, personal watercraft, and those involved in recreational activities that come into contact with different water sources. By prioritizing these vessels for inspection, the goal is to mitigate the chances of AIS spreading into pristine waterways, thereby protecting local ecosystems.

The other types of watercraft and categories mentioned do not capture the specific focus necessary for effectively preventing AIS transport. All trailers and all recreational boats can encompass a wide variety of watercraft, some of which may not pose significant risk in terms of AIS transport, while only focusing on fishing boats also narrows the scope and misses other categories that could be problematic from an AIS standpoint.
