Clayton, NY, Jul 27, 2011 — New York state is facing new pressure to scrap tough ballast water regulations that are set to go into effect next year. The rules are designed to stop invasive species from reaching the St. Lawrence Seaway and the Great Lakes.

But as Brian Mann reports, Republicans in Congress say New York should be stripped of hundreds of millions of dollars in Federal EPA funding if the regulations aren't scrapped.  Go to full article

Clayton, NY, Jul 19, 2011 — New York state is pushing forward with plans to implement tough new rules designed to keep ships on the St. Lawrence Seaway from bringing in invasive plants and animals. The regulations are set to go into effect in 2013.

Researchers say the Seaway has opened the door to dozens of foreign organisms that are wreaking havoc on native ecosystems.

But opponents of the rules, led by the Canadian government, say they're too strict and would stifle trade and commerce in the region. Brian Mann has our story.  Go to full article

Albany, NY, Jul 19, 2011 — Sheep - and cows and other livestock - can munch through a field in no time. In the process, they can upend the natural distribution of plants in the area.

Montreal, QC, Mar 31, 2011 — Last week, the first freighter of the year rumbled up the St. Lawrence River. That marked the 53rd season of the St. Lawrence Seaway, a man-made channel linking the Atlantic Ocean and the Great Lakes.

The Seaway's billion dollars of commerce is mostly an economic conversation between Canada's southern coast, America's Midwest, and the far-flung ports of the world.

But it's caused vast environmental damage in the North Country and across the Great Lakes, largely via invasive species.

David Sommerstein went to the Seaway's opening ceremony last week in Montreal. He sends this report on the Seaway's delicate balance between the economy and the environment.  Go to full article

Sackets Harbor, NY, Aug 17, 2010 — An update now on the invasive zebra and quagga mussels. Yesterday, we told you about the Sackets Harbor water treatment plant on the shore of Lake Ontario. It was nearly shut down last week after its intake pipe was so choked with mussels almost no water came through.

This morning, we hear from Dr Dawn Dittman. She's a researcher with the U.S. Geological Survey in Cortland, New York--and one of only a few people tracking the invasive mussels.

She says their numbers appear to be stabilizing. And she tells Jonathan Brown some popular sport fish--native to Lake Ontario--are starting to find zebra and quagga mussels quite tasty.  Go to full article

Scientists say the aggressive Asian carp -which can weigh up to 100 pounds--could wipe out natural fish stocks in Lake Ontario and the St. Lawrence River.

As Brian Mann reports, some lawmakers want new, permanent barriers that would prevent the fish from spreading.  Go to full article
