Eco impact of invasives on Great Lakes underestimated

New research from Wisconsin suggests the negative economic and ecological impacts of invasives in the Great Lakes is dramatically underestimated.

The study from researchers at the University of Wisconsin-Madison found just one non-native species in one inland lake triggered $80 million to $163 million in damages.

“Our study indicates that previous attempts to put a price tag on invasive species impacts haven't come close to the true cost," says Jake Walsh of the UW Center for Limnology and the lead author on the report recently published in the Proceedings of the National Academy of Sciences...
