- We often bring you stories of efforts to fight aquatic invasive species in the Northwoods during the summer. It's tempting to think that invasives don't pose a problem during the winter.
But conservation workers want you to rethink that idea. Species like Eurasian watermilfoil don't simply wither underwater in the winter.
"Eurasian watermilfoil is considered a perennial. However, I consider it an evergreen. A lot of people do," said Oneida County AIS Coordinator Stephanie Boismenue. "The reason being is it's winter-hardy. It's capable to live and grow underneath the ice."
Eurasian watermilfoil continues to spread throughout lakes in our area. To slow down that spread, people on the lakes need to be careful, even in the winter.
"If you're drilling a hole in the ice and you get plants that come up with it, you need to be mindful of that and do the same as you would during open-water season," Boismenue said.
Rules prohibit people from transporting plants from lake to lake during open-water season. The same is true in the winter.
