Upper Sugar River Watershed Association

The health of our favorite rivers and streams depends on all of us! Wisconsin's rivers are vulnerable to invasion by a number of aquatic invasive species (AIS), from Eurasian watermilfoil to Japanese knotweed. The key to successfully protecting our waters is detecting invasives early when it may still be possible to isolate or eradicate them, as populations detected early require less money and effort to manage. Volunteers are invaluable for early detection and rapid response. If left unchecked, AIS have the potential to reduce the diversity of native organisms, disrupt the food web, and impact recreational activities.
