National Invasive Species Act

The National Invasive Species Act (NISA) of 1996 is a U.S. law that aims to prevent the spread of harmful non-native species, especially through shipping activities. It enhances regulations on ballast water discharged by ships, which can carry invasive organisms across borders. The Act also establishes oversight and coordination among federal agencies to monitor and control invasive species that threaten America’s ecosystems, economy, and public health. Overall, NISA promotes responsible shipping practices and management strategies to reduce environmental impacts caused by species introduced into new areas where they can become invasive.
