Water Is Like Nothing Else - Great Lakes Invasive Species

On their home turf, plant and animal populations are kept in check by natural controls, like predators and food supply. However, when a species is introduced — accidentally or intentionally — into a new landscape that is not used to its presence, the consequences can be devastating. Most of these “non-native” species do not misbehave. But some non-native species spread unchecked by the lack of natural competitors and predators. They push out native species and cause ecological chaos. These are known as “invasive” species. All habitats are vulnerable to these invasions, from grasslands and forests to lakes, rivers and oceans.
