New law for Great Lakes ships

The St. Lawrence Seaway is now open to international ship traffic from the Atlantic Ocean to the Great Lakes. But as Sarah Hulett reports, the start of this year's Great Lakes shipping season is raising questions about a new state law aimed at protecting the lakes from invasive species.  Go to full article

States pass feds on invasives law

U.S. ports receive more than imported cargo. They often receive fish and other aquatic organisms from foreign ports. They stow away in the ballast water of cargo ships. Once in U.S. waters, some of the foreign species become invaders, damaging the ecosystem. The federal government has done little to stop these invasive species. Rick Pluta reports now some states have decided to take things into their own hands.  Go to full article

Multimillion dollar parasite fight continues

One of the most destructive invasive species in the Great Lakes was also the first one to arrive. The sea lamprey invaded the Lakes more than a hundred years ago, and no one's been able to get rid of it. As Rebecca Williams reports, it's the only invader in the Lakes that managers have been able to control... but it takes millions of taxpayers' dollars every year to keep the blood-sucking parasite in check, and there's no end in sight.  Go to full article

Predicting new invaders

There are over 160 non-native species in the Great lakes and St.Lawrence Seaway. If they impact native species, they're called "invasive." It's estimated that invasive species already cost the Great Lakes basin billions of dollars a year. The Great Lakes Radio Consortium's Zach Peterson reports that invasive species are also changing the ecosystem, crowding out the native species, and disrupting the natural food chain. And there will likely be more coming.  Go to full article

New research center for ballast treatment

Foreign, invasive species often get into U.S. waters by hitching a ride in the ballast water of ocean going ships. Now, a new research center will work to stop the spread of these invasive species. The research center hopes to develop new treatment systems aimed at catching the critters before they get out. The GLRC's Stephanie Hemphill has more.  Go to full article

Top Ten Threats to the Great Lakes: Predicting New Invaders

There are new problems for the Great Lakes on the horizon. As part of the series, "Top Ten Threats to the Great lakes", new invasive species are one of the ten threats. There are more than 160 foreign species in the Great Lakes now, and scientists are expecting others to make their way into the Great Lakes ecosystem in the near future. The outsiders crowd out and disrupt the natural food chain. As Zach Peterson reports, it's likely more will be coming.  Go to full article

"Invasives" Fight Needs People and Money

Non-native plant species like zebra mussels, water milfoil, and purple loosestrife are called "invasives." They can overwhelm native species, upsetting whole ecosystems. In the Adirondacks, private groups that have been fighting invasives for years are now hoping for public help. Invasives are considered one of the most serious threats to the region's, and the state's, environment. A state task force studying the problem brought its draft report and recommendations to a meeting in Ray Brook this week. As Chris Knight reports, members found a receptive audience, with its own suggestions.  Go to full article

Walt Lender Takes Over At Lake George Association

The Lake George Association is the oldest shore-owners' group in the United States. For 120 years, the organization has been protecting water quality and pushing for sound development on Lake George. Two years ago, the LGA lost a fight with the state and other pro-environment groups. The lake association wanted to use the chemical herbicide "Sonar" to battle an invasive water plant called Eurasian watermilfoil. Brian Mann spoke with Walt Lender, who takes over next week as head of the LGA. Lender says the organization will continue to push for smart development around Lake George -- and for use the of chemicals to fight invasive species.  Go to full article

Looking to the Environment Beyond the Garden

Invasive species are a growing problem in the north country. From purple loosestrife to Eurasian watermilfoil, alien plants are reshaping the region's environment. Gardeners and fish tank owners have introduced many of the worst species, bringing them in as decorative plants. But as Brian Mann reports, some gardeners are working to educate themselves--and to fight for a tougher response to invasives.  Go to full article

Water Gardens a Route for New Invasives

You can hear frogs croaking and chirping in the middle of a city these days. You can see cattails and water lilies out your window even if you live nowhere near a lake. Water gardens are all the rage. But some scientists are warning that we have to be careful with our gardens. If plants or animals get out of a backyard pond, they can endanger native species. the Great Lakes Radio Consortium's Chris Julin reports.  Go to full article
