Study Highlights Cost of Invasive Species
A new study by the University of Wisconsin-Madison highlights the hefty cost of controlling aquatic invasive species in the state’s lakes.

The study found that the estimated cost of controlling a single invasive species, the spiny waterflea, in just one lake could range from $86.5 million to $163 million over 20 years. Researchers believe study’s results show that a broader measure of the costs of controlling aquatic invasive species should be taken into account.

There are 37 types of invasive species in Wisconsin inland lakes, according to the department. Some of the state’s lakes have been untouched, while others are plagued with foreign species that could threaten their ecosystem.

The state Department of Natural Resources spends about $4 million annually on various efforts to control the spread of invasive species in inland lakes.
