Various aquatic invasive species (AIS) control efforts have been implemented in Vermont, and many are ongoing. DEC Aquatic Nuisance Control permits are available for local municipalities, watershed and lake associations, and other individuals who are involved in a myriad of control efforts around the state.

With over 800 lakes and ponds throughout Vermont, and 100 of those infested with aquatic invasive species, the Vermont Department of Environmental Conservation (VTDEC) staff annually monitor and survey priority lakes and ponds along with aquatic invasive species (AIS) considered a severe threat. During the growing season, VTDEC staff routinely survey and monitor Vermont waters to:

There are many ongoing programs in Vermont aimed at curbing the spread of invasive species and preventing new infestations. These initiatives are supported by Vermont DEC and often involve participation from landowners, watershed associations, and other interested volunteers.
