What to Look For

Aquatic Invasive Species (AIS) are species that enter into new ecosystems and spread, causing damage to native species and their habitants. These species are spread beyond their normal distribution, often as a result of human activities, and can threaten valuable environmental, agricultural or personal resources by the damage they cause.
