invasive species

The Asian carp captured this summer near the southern tip of Lake Michigan -- triggering a big scare -- apparently slipped past electric barriers.

Officials announced Friday that an autopsy of the 4-year-old fish showed that it originated in the Illinois/Middle Mississippi watershed, spending about a year in the Des Plaines River area.

It spent no more than a few months in the Little Calumet River before being captured on June 22, about nine miles from Lake Michigan.

In a long-awaited report, the U.S. Army Corps of Engineers says new measures are needed to prevent Asian carp from getting into the Great Lakes.

The report says the current defense at the Brandon Road lock in Illinois – an underwater electric barrier – should be beefed up. The Army Corps' recommended plan would add water jets and complex noises – like the underwater recordings of a boat motor.

Cayuga County officials want to prevent the spread an invasive species in Cayuga Lake, before it becomes impossible to contain.

Cayuga County Legislature Chair Keith Batman calls it a “devil weed.” He’s talking about hydrilla, one of the most invasive aquatic species in the world. It’s plagued Cayuga Lake for six years now, and measures to eradicate hydrilla in the Cayuga Inlet near Ithaca using herbicides have been successful. But last year, it was spotted further north in the lake.

The state Department of Environmental Conservation has designated this past week as Invasive Species Awareness Week. The goal is to encourage the public to help stop and reverse the spread of invasives. A group of volunteers from central New York has joined the battle.

The sharp scent of chemicals bites the air as Jason Krebill wades in a creek and pulls out two slippery, slimy, parasitic creatures.

He’s holding dead adult sea lampreys, one in each hand. They’re about two feet long, with suction-cupped mouths, lined with nearly a dozen rows of sharp teeth.

Like a vampire, the sea lamprey latches onto its prey and sucks the blood and nutrients out of fish in all five of the Great Lakes. Krebill, a biological science technician with the U.S. Fish and Wildlife Service, is a part of a team whose job it is to control the invasive species.

Officials continue to track the movement of the Emerald Ash Borer in Central New York.

Jessi Lyons of the Onondaga County Emerald Ash Borer Task Force says the parts of the Syracuse areas that are seeing the most activity right now are in transportation corridors.

The Nature Conservancy and other environmental groups are making use of a recently developed DNA sampling technique to determine whether or not any invasive species might be swimming, living or growing in the Oswego River and Erie Canal. By taking hundreds of water samples, the group believes it can slow the growth of invasive species in the state.

New York has a big problem with an invasive species you may have never heard of. Giant hogweed is a poisonous plant that can overtake entire fields with its giant leaves and can cause painful blisters on a person's skin. But the state Department of Environmental Conservation says it's stepping up its digging and spraying program to help control the plant and even eradicate it in some spots.

Homeowners in parts of Onondaga County with ash trees on their property, need to take action sooner than expected to deal with the Emerald Ash Borer. 

Jesse Lyons of the Cornell Cooperative Extension in Onondaga County says there’s evidence that the invasive insect has spread to almost  the eastern border of Onondaga County.

For years, the state Department of Environmental Conservation and other agencies have been trying to reduce the impact of invasive species like the Emerald Ash Borer and Asian carp. Last year, Gov. Andrew Cuomo signed into law the Invasive Species Prevention Act, requiring the DEC and state Department of Agriculture and Markets to come up with a plan to reduce the impact non-native plants and animals have on the state.

The agencies are now proposing regulations that prohibit knowingly selling, traveling with or introducing certain species into the state.

Congress is taking aim against invasive species that are clogging New York state's waterways, with New York representatives in the House and Senate backing the proposed "Invasive Fish and Wildlife Prevention Act."

It's a problem that plagues many lakes and rivers in central New York. Species like Asian carp and certain kinds of mussels can interfere with boating and recreation activities on the state's waterways. But championing the legislation is Sen. Kirsten Gillibrand (D-NY), who says these species can be difficult to deal with.

All summer long, the Department of Environmental Conservation is stationing college students at boat launches around New York with the mission to stop the spread of invasive species.
