Aquatic invasive animal species impact Vermont's ecosystems and recreational opportunities. These species can harm native animal populations and limit fishing and boating activities. However, there are many steps you can take to prevent the spread of these species and protect Vermont's waters. 

European water chestnut grows in slow-moving, nutrient-rich rivers and lakes and can grow in shallow waters to depths of 16 ft. In Vermont, water chestnut has been found in southern Lake Champlain and its tributaries, Mississquoi Bay, Lake Bomoseen, and several other lakes and ponds throughout the state.

Starry stonewort (Nitellopsis obtusa) can be found in slow moving rivers, lakes and ponds at depths of 3 to 95 ft. It prefers waters that are relatively high in calcium and phosphorus. In Vermont, starry stonewort is documented in Lake Memphremagog and Lake Derby.

European frogbit (Hydrocharis morsus-ranae) prefers calcium-rich, quiet waters such as marshes, swamps, ponds, slow-moving rivers and lakes, sheltered inlets and bays, and ditches. In Vermont, frogbit has been documented in southern Lake Champlain, Shelburne Pond, the Winooski River delta, the islands region of Lake Champlain, and Mississquoi Bay.
