This coming year likely will see some major policy decisions regarding the Great Lakes. Because the Lakes stretch out along eight states in the U.S. and two provinces in Canada, getting all the governments to agree on issues is a long and sometimes trying process. But those involved think 2005 will be the year that some real progress on Great Lakes issues will be made. The Great Lakes Radio Consortium’s Lester Graham recently talked with the chair of the U.S. Section of the International Joint Commission, Dennis Schornack. The IJC deals with disputes and advises the U.S. and Canadian governments on issues regarding the Great Lakes:


The International Joint Commission and the Government Accountability Office both have been critical of the U.S. government for not finding clear leadership on Great Lakes issues. Different agencies sometimes find their efforts overlap or conflict with others. At times, it seems there’s no organized effort to restore the health of the Great Lakes. Dennis Schornack says he thinks things were starting to get better because recently appointed U.S. Environmental Protection Agency Administrator Mike Leavitt took a real interest in the Great Lakes. But now Leavitt is leaving to become the new Health and Human Services chief.


“It’s going to be hard to beat the enthusiasm of Mike Leavitt. He spent literally about fifty percent of his time as EPA Administrator in the Great Lakes throughout. He was everywhere this past summer. But it does fall to the new administrator, whomever he or she may be; but in the meantime, the governors and mayors are proceeding forward on the priorities that they set over a year ago, and fleshing those out into very tight kinds of recommendations.”


Countless studies and reports on the Great Lakes point out one of the biggest threats to the lakes is invasive species. Those are foreign critters such as zebra mussels and round gobies that hitchhike in the ballast water of cargo ships, or are introduced unintentionally. Often the invasives damage the native fish, plants, and ecosystems of the Great Lakes. Nothing has been done to effectively stop importing the invasives, and some have gone so far as to suggest that the St. Lawrence Seaway connecting the Great Lakes to the Atlantic Ocean should be closed. The IJC’s Dennis Schornack says he’s hopeful that we’ll soon see laws that will do more to help prevent invasive species from getting into the Lakes.


“In the United States, at least, there is pending legislation that has been pending for over two years now called the National Aquatic Invasive Species Act. This legislation is overdue. It’s time for Congress to act on it. And in the ’05 legislative Congressional year, it’s time for them to act. And that’s the place where the standards get set, the authority gets established and where all of the rubber really hits the road. Now, that’s just in the United States. Bi-nationally, because the Great Lakes are a shared resource, the IJC, that I’m the chair of the U.S. section, has continued to advocate cooperation and collaboration between the two countries in terms of at least setting a common standard, a common rule, common regulation on the Great Lakes. Because, obviously, setting it on one side of the boundary line doesn’t do any good if the other side doesn’t follow.”


Another issue that’s recieved a lot of attention in the Great Lakes region recently is water diversion. A document called Annex 2001 tackles the issue of how much water can be used or withdrawn from the Lakes. The various state governors and province premiers put together draft agreements for public comment. Schornack says there’s been a huge response, and a lot of it hasn’t been positive.


“They recieved, I think, over ten-thousand public comments. And there is differing viewpoint, a growing difference between the view taken in Canada and the view taken in the United States on this effort. Canada, the province of Ontario, has come out and point-blank opposed the existing documents. There are concerns in Canada that this is just some kind of a ruse to somehow allow diversions of the Great Lakes waters to occur. I’m not part of that viewpoint, to tell you the truth. What’s being done right now and what will happen in 2005 is that the comments are being digested, we’ll see new draft documents come out from the governors and premiers and hopefully begin the process making those agreements stick.”


Schornack says 2005 will also see some important reports on the economic costs of invasive species. Studies on the logistics of shipping, cargo ship traffic and alternative freight haulers and design plans that look at the total cost of shipping – including the infrastructure costs and the environmental damage caused by invasive species. It should be an interesting year for the Great Lake if Congress moves on key issues, and then finds money to make the Great Lakes more sound.

Luring an Invasive Fish With Pheromones

A scientist has discovered a chemical compound that attracts an invasive fish. The
Great Lakes
Radio Consortium’s Mike Simonson reports that this could be a break through in
controlling
harmful fish populations:


Eurasian ruffe were introduced in the Duluth-Superior harbor from ballast water of
ocean-going
ships in the 1990’s. Ruffe reproduced so quickly, they now make up 80 to
90-percent of the fish
population, squeezing out native fish. Now, they’re spreading eastward across Lake
Superior
toward the lower Great Lakes.


University of Minnesota Fisheries Professor Peter Sorenson says he’s isolated a
pheromone that
will cause the fish to cluster in great numbers of male ruffe who are tricked into
thinking it’s time
to mate.


“It causes a great deal of sexual arousal and excitement. So to help detect this
thing, I suppose
like a dog they get a little crazy and just start swimming around like crazy and
nudging and
inspecting the fish in the tank.”


Once they’re clustered, Sorenson says it may be possible to find a way to cut their
population.
Sorenson hopes to find a similar pheromone in carp and sea lamprey, other invasive
species
which threaten native fish in the Great Lakes.

Audubon Society Cheers Congress for Bird Law

The National Audubon Society is praising Congress for strengthening protections for American migratory birds. The Great Lakes Radio Consortium’s Erin Toner reports:


The U.S. Migratory Bird Treaty Act was passed in 1917 to protect native birds, such as the woodpecker, the Baltimore Oriole, and the American Black Duck. But a court ruling earlier this year changed the law, by extending protections to all birds, including non-native species. National Audubon Society spokesman John Bianchi says invasive species like the European Starling are pushing out native birds.


“That is hard for people to understand, but the equation there is that pushing out means killing. A European Starling pushing a woodpecker out of its nest means that that woodpecker will not breed that year.”


As part of a recent spending bill, Congress amended the law to once again only protect native migratory birds. That provides millions of dollars a year for protection efforts, which can include trapping and removing non-native birds, or killing them.

Invasive Fish Rears Ugly Head in Great Lakes

  • With its ability to breathe out of water and wriggle its way over land during dry spells, the media has dubbed the northern snakehead "Frankenfish." Its appearance in Lake Michigan is scary to scientists. (Photo courtesy of USGS)

A few weeks ago, a Chicago fisherman caused a stir when he found a northern snakehead fish. The discovery set off a frantic search to find out if yet another invasive species is threatening the Great Lakes. The Great Lakes Radio Consortium’s Jenny Lawton has this report:

A few weeks ago, a Chicago fisherman caused a stir when he found a northern snakehead fish. The find set off a frantic search to find out if yet another invasive species is threatening the Great Lakes. The Great Lakes Radio Consortium’s Jenny Lawton has this report:


Just before Halloween, the so-called Frankenfish reared its ugly head… filled with sharp teeth… in Chicago’s Burnham Harbor on Lake Michigan. And it’s still a mystery as to just how it got there.


Although the snakehead is arare item in some Asian cuisines, there’s a more common suspicion amongst local experts and hobbyists. That snakehead was probably a pet that outgrew its tank, and instead of the traditional farewell down the toilet, it was set free in Lake Michigan. Free to eat through the Lake’s food web.


Local pet store manager Edwin Cerna says that’s why he stopped selling the fish years before they were banned by U.S. Fish and Wildlife. He remembers one day, when he was adjusting a tank, he accidentally got in between a snakehead’s lunch and its mouth.


“He bit me in the hand… made me bleed. It hurts. It’s got a nice strong jaw and that’s why it’s so dangerous because it can kill big fish, literally cut them in half. It’s almost like a big old killer whale, like a miniature version of it.”


But why on earth would anybody buy a vicious fish that can grow up to three feet long in the first place? Jim Robinett is with the Shedd Aquarium in Chicago. He says he’s a fish geek.


“I gotta say, as a little fish, when you first buy them, they’re really attractive; they’re neat little animals, but they eat like crazy. They’re voracious.”


Robinett knows not to be fooled by the little guys because what happens next is the perfect plot for a B-horror movie. He says the snakehead fish grows quickly, eventually eating everything in its tank. If it doesn’t die from overgrowing that tank, its owner might be tempted to dump it into a nearby body of water where it will keep eating its way up the food chain. Robinett says that’s the fear in Lake Michigan.


“They could potentially start picking off small salmon and lake trout, which is native to these waters here, they’re not real discriminating, they’ve been known to take things as large as frogs, some small birds, even small mammals that happen to get in the way there close to shore. They’ll eat anything they get their mouth on.”


Most hobby fish don’t last long in Chicago’s cold water. But the northern snakehead is different. The snakehead is native to northern Asia, and the Lake Michigan Federation’s Cameron Davis says that makes the fish feel right at home around here.


“It’s a lot like us Midwesterners, it just kind of hunkers down and… that’s part of the problem with the snakehead is that it can live under very extreme conditions. Which means it’ll out compete those other fish, and that’s a tremendous problem.”


Snakeheads have another edge on other species. The fish guard their eggs, giving their young a better chance of reaching maturity. But perhaps the most peculiar thing about snakeheads is that they can breathe. In addition to its gills, they have an organ that works like a lung and allows it to breathe air. It’s able to live up to three days as it uses its fins to wriggle across land in search of another body of water.


But looking down into the murky waters at Burnham Harbor, Davis says we shouldn’t run screaming yet. It’s not exactly a horror film scenario.


“I don’t think that the snakehead is going to come and grab our children out of schools and eat them or anything like that. But it is a problem for those of us who like to fish for yellow perch and whitefish and some of the things that make the Great Lakes so fantatstic, could really be threatened by this fish getting into Lake Michigan.”


Other invasive species cause an estimated 137-billion dollars of losses and damages in U.S. waterways each year. Cameron Davis says simply banning the local sale of fish like snakeheads hasn’t been enough to keep the Great Lakes safe.


“We’ve got to stop imports of these kinds of fish into the United States. We can’t protect the Great Lakes unless we’re checking these things at the door when they come into the country. It’s that simple.”


Davis is pushing for the passage of the National Aquatic Invasive Species Act. The bill would allocate a total of 174-million dollars to develop new technology for identifying and eliminating the invaders if and when they arrive.


So far, local authorities ahven’t found another snakehead near the banks of Lake Michigan, but Cameron Davis says the initial find just proves how hard it is to regulate what comes into the country’s largest body of fresh water.


Standing on the dock at Burnham Harbor, Davis looks out over the dark waters and shakes his head.


“It’s just an indicator that we’re in a race against time right now. Let’s hope that if there are more than one out there, that they haven’t hooked up.”


If they have, he says, it could truly be the stuff horror movies are made of… at least, for the other fish in the Great Lakes.

Gl States Speak Up on Ballast Water Lawsuit

A lawsuit brought by several environmental groups in California seeks to increase protection against invasive species.

A lawsuit brought by several environmental groups in California seeks
to increase protection against invasive species by forcing the
Environmental Protection Agency to regulate ballast water discharge.
Now, officials from the eight Great Lakes states are writing in to
support these groups in their lawsuit. The Great Lakes Radio
Consortium’s Celeste Headlee reports:


Researchers say ballast water from oceangoing ships is one of the
primary methods by which invasive species enter the Great Lakes.
State Attorney General Mike Cox wrote the amicus brief for Michigan.
He says under current EPA rules any ship that claims it doesn’t have
ballast can, in fact, issue discharge into the water.


“Now we know that right now and on any given day, about 85 to 90
percent of these ships claim that they don’t have any ballast on board.
That’s a claim that stretches credulity, quite simply because all ships
need ballast if they don’t have cargo.”


The National Oceanic and Atmospheric Administration estimates that it
costs 45 million dollars a year just to control zebra mussels and sea
lampreys in the Great Lakes. Cox and the seven other Great Lakes
Attorneys General say the EPA must do more to protect the waters from
invasive species. The AGs have filed eight separate amicus briefs
supporting the case against the government. For the Great Lakes Radio
Consortium, I’m Celeste Headlee.

Gardeners Have Hand in Invasive Species Control

Gardeners have been ordering new plants and digging in the dirt this spring, but, if
they’re not careful, they could be introducing plants that can cause havoc with forests,
lakes, and other natural areas. Gardeners can’t count on their suppliers to warn them
about plants that can damage the local ecosystems. In another report in the series “Your
Choice; Your Planet,” the Great Lakes Radio Consortium’s Lester Graham reports:


Gardening, especially flower gardening, seems to get more popular all the time. Maybe
it’s because the baby-boomers have all reached that age where they’re beginning to
appreciate stopping for a moment to smell the roses.


That’s fine. In fact if gardeners plant the right kinds of plants… it can be great for
wildlife. There are all kinds of guides for backyard natural areas.


But… in some cases… gardeners can unleash plant pests on the environment.


Katherine Kennedy is with the Center for Plant Conservation. She says almost all of the
problem plants that damage the native ecosystems were planted with good intentions…


“I don’t believe that any invasive species has ever been introduced into the United States
on purpose by someone who willingly said, ‘Oh yeah, this is going to be a problem, but I
don’t care.’ They’ve almost all been inadvertent problems that were introduced by
someone who thought they were doing something good or who thought they were
bringing in something beautiful.”


English ivy, a decorative ground cover, is now killing forests in the Pacific Northwest…
kudzu is doing the same in the southeast… and in the Great Lakes region and the
Midwest… pretty flowering plants such as purple loosestrife and water plants such as
Eurasian watermilfoil are causing damage to wetlands, crowding out native plants and
disturbing the habitat that many wildlife species need to survive.


Bob Wilson works in the Michigan Senate Majority policy office. Like many other
states, Michigan is looking at legislation to ban certain problem plants. Wilson agrees
that these plant pests are generally not intentional… but they do show that people seem to
unaware of the problems that they’re causing…


“The two most common vectors for bringing in these kinds of plants are typically
landscapers, who bring it in as a way of decorating yards and lawns, and then aquarium
dumpers, people who inadvertently dump their aquarium, thinking that there’s no
consequence to that. Before you know it, something that was contained is now spread.”


But stopping the import of pest plants is a lot harder than just passing laws that ban them.
With mail order and Internet orders from large nurseries so common, the plants can get
shipped to a local nursery, landscaper or local gardener without the government ever
knowing about it.


Recently, botanists, garden clubs, and plant nursery industry groups put together some
codes of conducts. Called the St. Louis Protocol or the St. Louis Declaration… the
document set out voluntary guidelines for the industry and gardeners to follow to avoid
sending plants to areas where they can cause damage.


Sarah Reichard is a botanist with the University of Washington. She helped put the St.
Louis Protocol together. She says if a nursery signs on to the protocol, it will help stop
invasive plant species from being shipped to the wrong places….


“And it’s up to each of the nursery owners, particularly those who sell mail order or
Internet, to go and find out which species are banned in each state.” LG: And is that
happening?
“Uh, I think most nursery people are pretty responsible and are trying to
do the best that they can. I’m sure that they’re very frustrated and understandably so
because the tools aren’t really out there for them and it is very difficult to find the
information. So, it’s a frustrating situation for them.”


But in preparing this report, we found that some of the biggest mail-order nurseries had
never heard of the St. Louis protocol. And many of the smaller nurseries don’t have the
staff or resources to check out the potential damage of newly imported plants… or even
to check out each state to make sure that banned plants aren’t being sent inadvertently.


Sarah Reichard says that means gardeners… you… need to do some homework before
ordering that pretty flowering vine. Is it banned in your state? Is it a nuisance that could
cause damage? Reichard says if enough gardeners care, they can make a difference…


“You know, gardeners have tremendous power. We, you know, the people that are
buying the plants at the nurseries – that’s what it’s all about. I mean, the nurseries are
there to provide a service to provide plants to those people and if those people have
certain tastes and demands such as not wanting to buy and plant invasive species, the
nurseries are going to respond to it. So, we’re all part of one team.”


Reichard and others concerned about the problem say although agencies are working on
it… the federal government has not yet done enough to effectively stop invasives from
being imported and shipped to the wrong areas. They say it’s up to the nurseries, the
botanists, and the gardeners to stop them. If not, we’ll all pay in tax money as
government agencies react to invasives with expensive eradication programs to try to get
rid of the plants invading parks, preserves, and other natural areas.

Gardeners are being asked to be careful about what they plant. Invasive species that
cause damage to natural areas often start as a pretty plant in someone’s yard. The Great
Lakes Radio Consortium’s Lester Graham reports:


Botanists, plant nurseries and gardeners are all being asked to do a little more homework
before importing, selling, or planting new kinds of plants. Katherine Kennedy is with the
Center for Plant Conservation. She says some of the plants you mail order from the
nursery can end up being invasive kinds of plants that damage the local ecosystem…


“We are actually at a point where these invasions crowd out the native community, not
just a species or two, but the entire community. And the wildlife value falls and the
native plants are displaced. And, so, the destructive potential for a species that becomes
truly invasive is more immense than I think many people realize.”


Kennedy says you can’t count on the nursery to warn you when you order plants. She
says gardeners have to make sure the plants they’re ordering won’t hurt the surrounding
landscape.

Appreciating the Exotics

If you live in a city or a suburb, chances are that you see non-native
species every day. They might be birds originally from Europe, or a
tree imported from Asia. They’re almost always referred to as pests and
weeds. Great Lakes Radio Consortium commentator, Chuck Staresinic
, suggests that instead of despising these invaders,
perhaps we should admire them. At the very least, we should get used to
them:

Great Lakes Fishing Industry Remembered

Like many Great Lakes harbor towns, the days of busy fishing villages
on the waters of Lake Superior are gone. Now these towns are mere
shadows of their heyday, and only a handful of commercial fishing boats
still cast their nets. Pressures from sport anglers and exotic species
have dramatically changed the industry over the past four decades. The
Great Lakes Radio Consortium’s Mike Simonson examines how these towns
are trying to rediscover that history:
