Aquatic Invasive Animals

Use LIEP to learn more about common aquatic invasive animal species found in Vermont waters. 

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. 

Water Chestnut

European Water Chestnut

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

Starry Stonewort

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

European Frogbit

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.

Japanese Knotweed

Japanese Knotweed

Japanese knotweed (Polygonum cuspidatum) is usually found in wet habitats, along river and stream banks, and in disturbed areas such as roadsides and old fields. In Vermont, knotweed covers miles of shoreline on every major river in the state.

What Posting Means

The Vermont constitution has protected the right to hunt, fish and trap on open, private land since its drafting in 1793.

Posting laws and regulations honor this commitment while also ensuring landowners have the protections they need to control their property.
