Which of the following states requires high-risk inspections?

South Dakota is known for requiring high-risk inspections primarily because of its geographical position and local water bodies, which can be at risk for invasive species. The state has specific enforcement and monitoring measures in place to help prevent the introduction and spread of aquatic invasive species (AIS) into its waterways. These inspections are part of an effort to protect the aquatic ecosystem, natural resources, and recreational opportunities available to residents and visitors alike.

The focus on high-risk inspections involves checking boats and equipment that are most likely to harbor invasive species, especially those coming from areas known for having infestations. This proactive measure helps to mitigate potential ecological damage and economic costs associated with invasive species, making South Dakota's approach unique compared to other states listed that may have different policies or focus areas for inspection.

The other states listed may have measures in place to manage AIS but may not emphasize high-risk inspections as a standard requirement or may categorize risks and inspections differently in comparison to South Dakota’s approach.
