European frog bit It’s Floating leaves are heart-shaped and 1-2 inches wide. Native to Europe Asia and Africa Got to newyork via Canada Gets rid of all natural wildlife in pond by pushing plants on top out and killing underwater plants by blocking sunlight Kills native plants Only way to get rid of it is to pull it out by hand

Curly leaf pondweed Its from Africa curlyleaf pondweed was accidentally introduced to U.S. waters by hobbyists in the mid 1800's. Although curlyleaf can provide habitat for aquatic life during the winter when few other plants are present, the negative consequences of this plant far outweigh. It makes it hard for boats,swimming,and fishing. Its hard to control but you can burn it.

Fan wort Fanwort is a highly competitive plant that is capable of rapid growth and spread. Native in southern north America not northern Once established, Fanwort can negatively impact and out- compete native vegetation. Fish and animals that were dependent on the native vegetation must relocate or perish, leading to a decline in biodiverse Although harvesting can greatly reduce the Fanwort biomass in a water body, harvesting causes fragmentation and fragments are capable of producing new plants.

Hydrilla The dioecious form of Hydrilla is believed to originate from the Indian subcontinent The monoecious form is believed to have arrived on our shores from Korea. Hydrilla can invade deep, dark waters where most native plants cannot grow. Mechanical harvesting and herbicide spraying are common control methods of controlling Hydrilla. Both are expensive and only moderately effective.

Water chestnut The water chestnut was first introduced to North America in the 1870s, where it is known to have been grown in a botanical garden at Harvard University in 1877. The plant had escaped cultivation and was found gr The plant can form nearly impenetrable floating mats of vegetation. It is much easier (and less expensive) to control newly introduced populations of water chestnut. Therefore, early detection and a rapid response are the key to preventing substantial, high-impact infestations.

Asian clam Asia Reproduces in large colonies that can clog waterways and pipes On intake pipes, chemicals can be used that will kill the larva. If these chemicals were used in an open lake they would also affect fish and native mussels.

Round goby Round Gobies are bottom-dwelling fish that were introduced to the Great Lakes from central Eurasia via the ballast water of large, ocean going cargo ships. Eats all bottom dwellers from other fish Compete with other wanted top catch fish Get rid of by spotting to local reaserchers

White perch White perch came from the Atlantic coastal region in brackish water. White perch are predacious and opportunistic feeders, often feeding on the eggs of walleye. Remove fouling organisms from hull, piping, and tanks on a regular basis and dispose of any removed substances in accordance with local, state and federal regulations.

Alewife They were typically found from Newfoundland to the Carolinas, preferring depths of approximately 150 to 350 ft off the coast Alewives have fundamentally altered the Great Lakes ecosystem. Since their invasion, all trophic levels have been effected by their extensive predation of zooplankton Increasing the effort to re-introduce Atlantic salmon to the area would certainly help, as well as increasing support for native species that may feed on alewife eggs

Bloody red shrimp The bloody red shrimp is native to the Ponto-Caspian region of eastern Europe They may compete with young fish, while providing food for larger fish. Bloody red shrimp are currently found in all of the Great Lakes of North America.
