Predicting the next invasive species allows us to take action before they reach our waterways—an economically and environmentally smarter approach than responding after they’ve arrived.

To get a jump on potential invaders, scientists have developed methods that pinpoint the risk a species poses to specific environments based on factors like history of invasion, its ability to survive in similar habitats, and how difficult it is to control. Using these tools and the information they provide, natural resource managers, environmental educators and individuals who buy and sell live aquatic organisms can make more informed decisions on how to protect their waterways from potential AIM.
