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.

Eurasian Watermilfoil

Eurasian Watermilfoil

Eurasian watermilfoil (Myriophyllum spicatum) tolerates a variety of conditions; it can grow in fresh or brackish waters, a range of temperatures and soil pHs, and disturbed and polluted areas. It is typically found in ponds, lakes, and slow-moving rivers at depths of 3 to 33 ft. In Vermont, Eurasian watermilfoil is widespread throughout Lake Champlain and the state in general with populations documented in more than 80 waterbodies.

Aquatic Invasive Plants

Eurasian Watermilfoil

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

Aquatic invasive plant species impact Vermont's ecosystems and recreational opportunities. These species can reduce native aquatic plant diversity and abundance and inhibit boating and swimming. However, there are many steps you can take to prevent the spread of these species and protect Vermont's waters. 

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.

Native Plant Sources

Native plants are critical to healthy, functioning ecosystems. They provide habitat and food sources for many species, preserving biodiversity. Native plants can also aid in flood resiliency and water quality improvement.
