DOMINIC, DEAN
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 outcompete 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.
