The state of North Dakota has been at the center of an international water dispute with the Canadian government. Great Lakes Mayors and governors are watching the issue closely. They fear the political fallout from this dispute could affect how Great Lakes water is managed. The Great Lakes Radio Consortium’s Shawn Allee has more:
To fight flooding in North Dakota’s Devils Lake area, state officials plan to divert some lake water into a river system that flows north into Canada. Canada claims the diverted water might pollute rivers and lakes there, but North Dakota disputes such claims.
Great Lakes mayors are taking Canada’s side in asking that the International Joint Commission review the issue. The IJC has resolved water disputes between Canada and the U.S. for nearly a century.
Frank Merritt of the Legal Institute of the Great Lakes says officials worry states and provinces might go it alone in planning water use.
“If we allow the movement of water on a unilateral basis, we will lose control, and all the world that wants fresh water will come to the Great Lakes and get it.”
The U.S. hasn’t responded to Canada’s year-old request to move the issue to the IJC.
The clock is ticking. North Dakota says it will begin diverting Devils Lake water July 1st.

Across the Great Lakes region the recovery of the cormorant is booming. But some anglers and resort owners think the cormorants are eating too many of the fish that people like to eat. In some areas, wildlife managers have resorted to killing cormorants on popular fishing lakes. In one case, critics say there’s not enough evidence to justify the killing. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:
Larry Jacobson is the third generation in his family to run the Hiawatha Beach Resort on Leech Lake, about two hundred miles north of Minneapolis. Three years ago, on fishing opener weekend, all of his twenty-one cabins were full. This year, he had no guests. Jacobson says the word has spread that fishing is down on Leech Lake. He blames the cormorants. The birds nest on a small island in the south end of the lake. Eight years ago, there were fifty nests; last year, there were two thousand five hundred.
“The cormorants eat about a pound fish a day. The way the population was just exploding out there, you could see writing was on the wall, that this was really going to make dramatic impact.”
Jacobson says his guests are still catching big walleye, but the smaller, pan-sized walleye are getting hard to find.
There are several reasons why the walleye population might be down, but Jacobson and other business owners blame it on the cormorants, and they’ve asked the Department of Natural Resources to do something about the birds.
“Leech needs to be maintained as high quality fishery. There’s such an economic impact to the area from walleyes, that if you don’t maintain it that way, everyone’s going to be suffering.”

Resource officials are responding to the resort owners’ concerns. The Leech Lake Band of Ojibwe owns the island. John Ringle is wildlife manager for the tribe.
“Okay we’re headed right at Little Pelican Island right now.”
Little Pelican Island is about three acres of sand and scruffy shrubs. Hundreds of cormorants cover the shore. Ringle says they fish out here in the open waters of Leech Lake.
“They’re omnivorous so they’re eating all sorts of different varieties of fish. Right now they’re probably eating large numbers of perch.”
Ringle is working with state and federal agencies to reduce the number of cormorants nesting here, eating fish, and crowding out other birds, such as the endangered common tern.
Normally, cormorants are a federally protected bird, just like eagles. That’s because they were almost wiped out by the insecticide DDT before it was banned in 1973. But a new rule allows resource officials to harass and even kill cormorants where they’re damaging other wildlife.
This summer, workers are sitting in hunting blinds on Little Pelican Island, shooting cormorants. They use air rifles to make as little noise as possible, so the other cormorants aren’t spooked away.
So far, they’ve killed more than two thousand birds. They plan to leave about five hundred nesting pairs alive. Ringle says nobody’s happy about shooting cormorants, but he says he thinks it’s necessary.
RINGLE: “My philosophy is that as mankind utilizes the resource, we have to manage them, we’re not in finite supply.”
HEMPHILL: “Do you think we know enough to manage them?”
RINGLE: “Not really. I think the public is demanding action prior to any conclusive study being conducted.”
And that’s a big problem for Francie Cuthbert. She’s a professor and cormorant researcher at the University of Minnesota. Cuthbert says the agencies that want to cut down the cormorant population skipped an important part of the management process: finding out what’s actually happening on Leech Lake.
“They’re really being driven by complaints from citizens and resort owners who are concerned about local economics, and who just don’t like the birds; they’re afraid of the numbers. If we responded to all natural resources conflicts this way, we’d be in a state of chaos.”
Cuthbert says even with the cormorants’ dramatic comeback since the days of DDT, there still aren’t as many as there were a hundred years ago. She says rather than kill cormorants, wildlife officials should try to boost the number of fish.
The state of Minnesota is working on that. It’s stocking Leech Lake with walleye for the first time this year. Conservation officials are studying some of the birds they killed to find out what they’re eating. And the state is also limiting what size of walleye anglers can catch so the fish can recover.
That makes resort owners like Larry Jacobson nervous, because he says a lot of anglers don’t like the limits. But at least he’s glad someone’s doing something.
“The fishery is a business, there’s no question about that. If you want to sustain our economy in this area, you’ve got to manage the lake.”
Workers will continue shooting cormorants occasionally through the summer. And the control effort could continue. Experts say it’ll take several years for the fish to recover enough to draw anglers back to the lake.

There are new concerns that products we use every day to keep us clean and make us beautiful may contain toxic chemicals. The targets are things like shampoos, deodorants, hair dyes and cosmetics. Some companies are taking these concerns seriously and giving themselves a makeover. The Great Lakes Radio Consortium’s Julie Halpert has this story:
(Sound of woman and child talking)
Teri Olle is playing dress-up with her two-year-old daughter, Natalie, in the family’s bathroom. Teri is applying lotions to her daughter’s chubby cheeks, while Natalie puts lipstick on her mother.
Little girls like Natalie have been playing dress-up for generations. But Natalie’s game is slightly different. She’s using nail polish, lipsticks and creams made without man-made chemicals.
That’s because her mother is an environmental activist who lobbies against toxic chemical use. With cosmetics, her biggest fear is a group of chemicals called phthalates. Phthalates increase the flexibility of plastic and keep nail polish from chipping.
“Phthalates are testosterone-suppressing synthetic hormones, essentially. And they’ve been linked with all sorts of developmental problems, including, most dramatically, a set of male genital defects that show themselves as birth defects in infant boys.”
Last month, scientists released the first study on male babies. They found a strong link between high levels of phthalates exposure in pregnant women and damage to their sons’ reproductive tract. Studies like this, and others on lab animals showing possible links to reproductive problems, prompted the European Union this past March to ban two types of phthalates from all products sold in Europe. The states of California, New York and Massachusetts are also considering similar plans.
Olle is five months pregnant with her second child. She doesn’t know if she’s carrying a boy, but she says chemicals in cosmetics could be risky for any fetus. So she’s not taking any chances.
“For me, as a person, if someone said to me, ‘You can either use this product that may cause a genital defect in your baby boy or not’, I would think most people would go, ‘Really, we probably shouldn’t be using these products.'”
And it’s not just phthalates that could be a problem. Environmentalists say that the ingredients in cosmetics haven’t been evaluated for health or safety effects. The Food and Drug Administration doesn’t do that kind of testing. And in 60 years, it’s banned only nine ingredients. So there are other chemicals, like coal tars used in hair dyes and formaldehyde used in nail polish, that might cause health problems as they’re absorbed by the skin into the bloodstream.
Because of these concerns, a group of environmentalists called the Campaign for Safe Cosmetics has convinced 136 natural cosmetics companies to sign a pledge to check for potentially toxic chemicals and eliminate them.
One of those companies is Avalon Organics. Over the past year, Avalon’s spent two and a half million dollars to reformulate their products and switch to more natural alternatives. Gil Pritchard is the company’s President and CEO. He says the jury’s out on whether these chemicals definitely cause harm. Even so, he didn’t hesitate to make the investment.
“It’s convincing enough for me and our company to exercise what we call a precautionary principle – to adopt it and say look, we may not have direct scientific evidence, but there’s enough evidence here to say whoa, I can feel the heat from the stove. I don’t need to put my finger on and burn myself to know that that’s one of the likely outcomes.”
But not all companies feel this way. Procter & Gamble, in Cincinnati, Ohio, has not signed the pledge. Nor have any other major cosmetic companies. Tim Long is a company spokesman. He says environmentalists are blowing this issue way out of proportion.
“The amounts of most of these ingredients that the activists have concerns about are, in fact, extremely small and at the doses used in our products, there’s no scientific evidence to support that they’re resulting in any harm to consumers.”
Long says Procter & Gamble complied with the EU directive and took the banned phthalates out of all of its products both in Europe and the U.S. But he says that wasn’t necessary, since phthalates, along with all other cosmetic ingredients, simply aren’t dangerous. He says his company wouldn’t be using them if they were. And the FDA says that these cosmetics are safe.
Environmentalists say that more research needs to be done to better understand the effect of chemicals used in cosmetics on the body. But Teri Olle says that with so many natural alternatives available, it makes sense to be careful.
“When I became pregnant, I definitely became more conscious of what I was putting on my body. I mean, if you’re supposed to avoid soft cheeses and cake batter, it certainly can’t be good for you to be spraying petrochemicals on your body. That definitely can’t be good for the baby.”
So when the baby’s born this September, instead of using products with man-made chemicals, Teri Olle will be spreading diaper rash ointment with beeswax and apricot oil on her newborn baby.
The Government Accountability Office is telling the Forest Service to improve how it deals with the woody material it clears from forests. (Photo courtesy of the USDA)

The government’s effort to reduce wildfires in forests has some side effects. A Congressional watchdog agency says the U.S. Forest Service isn’t doing a very good job of dealing with the side effects. The Great Lakes Radio Consortium’s Lester Graham reports:
The Forest Service clears out a lot of smaller trees, limbs, and underbrush from forest floors. The idea is to remove what could become fuel for wildfires. Generally, the material is turned into wood chips. The wood chips can be used as fuel or in wood composite products for construction.
The Departments of the Interior and Energy have been working together to try to find new ways to use what the government calls the “woody biomass.” But the Forest Service doesn’t have anyone coordinating with the other agencies.
The Government Accountability Office is calling on the Forest Service to appoint someone to take responsibility for overseeing and coordinating the agency’s “woody biomass activities.” The GAO indicated the material currently has little or no commercial value, but finding new markets for it would be helped if the Forest Service coordinated its efforts with the other agencies.

In the last century, the increase in shoreline development has driven a
small and rare bird close to extinction. Each spring, the Piping Plover
nests along the shores of the Great Lakes. The Great Lakes Radio
Consortium’s Tom Kramer gives us an update on the effort to protect the
bird:
The Great Lakes population of Piping Plovers has been on the endangered
species list since 1986, when the number of nesting pairs dwindled to 17.
These days the number of nesting pairs is up into the 50’s. But biologists
say the bird still needs protection.
Lisa Gamero coordinates the Piping Plover Patrol for the Michigan Department
of Natural Resources. Gamero says nesting sites are becoming scarce as the birds compete with
people for lake frontage.
“Their habitat needs are basically, kind of a wide open beach, with a lot of small pebbles or cobbles, sand, and they usually have to be within a hundred feet of the water, and the nearest vegetation needs to be about a hundred feet away from where they decide to put their nest.”
The plover will remain on the federal endangered species list until its
numbers increase to 150 healthy nesting pairs, for 5 consecutive years.

All eyes are on the south right now for signs of a potentially
devastating fungus that attacks soybeans. A serious outbreak there could
bring soybean rust to the Midwest – where most of the nation’s soybeans are
grown. The Great Lakes Radio Consortium’s Tracy Samilton reports:
Soybean rust spores are carried on wind currents, so it is easily spread.
So far this year, only Georgia has had a small outbreak.
Ray Hammerschmidt is a plant pathologist at Michigan State University. He
says every step is being taken to protect soybean crops, including dotting
the Midwest with what are called sentinel plots.
“And once a week, starting in a few weeks, each of these plots will be scouted very intensively, looking at at least a hundred plants, looking for any signs or symptoms of the disease.”
Advance warnings will allow farmers to apply fungicide to their crops as
soon as possible. Soybean rust can’t overwinter in the cold north.
So if southern states have good luck – or do a good job treating it – it’s less
likely to make it here.

With the return of summer comes the return of Recreational Vehicles, or RVs, from their winter homes in the South. Nicknamed “road whales,” most of those homes on wheels have a bad reputation as gas guzzlers, but some of them are saving energy once they’re parked.
Solar systems mean the RVs don’t plug in to use electricity. Instead, they get some of their power from the sun. The Great Lakes Radio Consortium’s Cari Noga reports:

With the return of summer comes the return of recreational
vehicles – RVs – from their winter homes in the South. Nicknamed
“road whales,” most of those homes on wheels have a bad reputation as
gas guzzlers. But some of them are saving energy once they’re parked.
Solar systems mean the RVs don’t plug in to use electricity. Instead,
they get some of their power from the sun. The Great Lakes Radio
Consortium’s Cari Noga reports:
Michigan RV owners, Bruce and Yvonne Banninger, take all the comforts of home along when they hit the road. Their big RV has a flat screen TV, surround sound, and even an electric bread maker. But they don’t have to hook up to power at an RV park, or start up a portable generator. To run all those appliances from the remote places they like to park, the Banningers rely on three solar panels mounted on the roof of their RV. Bruce Banninger says he wouldn’t want to motor home without the panels.
“We do a lot of boondocking, they call it, or not being plugged in. We like to just park out along a stream or a lot of places like that and you need power, and I don’t like running the generator all the time. And so the solar panels pretty much take care of it. On a sunny day.”
The Banningers have had solar since they got their first RV in 1992. Bruce Banninger says the fairly low cost, lack of maintenance, and the environmental benefit are the biggest reasons why RV owners like solar.
“I figure that for every panel that we have – solar panel – we can save running the generator one hour a day. And so when you figure out long term, that’s quite a savings. And you’re not burning a non-replaceable fuel. The sun, hopefully, will shine a long time yet.”
The Banningers have relied on their solar panels everywhere from California to the Everglades and on up into Canada. They found most U.S. National Parks don’t have electrical hookups, making solar pretty handy there.
“There’s something neat about being able to park out anywhere, and have all the power you need. It’s a good feeling; you’re self-sufficient.”
There’s not a lot of data on how many RVs use solar panels. But solar suppliers and RV manufacturers agree that it’s an option more RV-ers are choosing these days. The independent Michigan supplier who sold Banninger his panels has seen it. John Heis says most of his work is on homes, but people in his line of work in the South can earn a living just off the RV market.
“There’s a quite a market there to be done with RV people, certain parts of the United States where RV-ers live year-round, there are people that do make a living doing just that.”
Besides small dealers like Heis, large companies are finding a niche in RV solar too. Randy Bourne works at ICP Solar, a Canadian company that makes mobile solar products, like panels for RVs and boats. He says RVs are the company’s biggest market.
“Business has at least doubled over the past three to four years.”
Bourne says both consumers and manufacturers are demanding solar. One Oregon manufacturer, Monaco Coach, now offers a solar panel standard on its top-of-the-line model. Solar panels are optional on other Monaco models. They all come pre-wired so solar can be added later.
On RVs, solar panels charge the batteries that support the typical electrical systems. As RVs get bigger and more elaborate, new kinds of appliances and alarm and safety systems require power even when not in use. Randy Bourne says solar’s perfect for that.
“Solar and batteries go hand in hand. What the solar panels are doing now is putting in a small trickle charge to keep that battery well-maintained for a longer period of time.”
Cost depends on the extent of the system. Banninger estimated it cost him two thousand dollars for the panels and controller he installed five years ago. Today, Bourne says basic one-hundred watt panels cost between seven-hundred and nine-hundred dollars installed. That’s a relatively inexpensive option to add to high-end RVs, which can carry a price tag well into six figures.
RVs still use a tremendous amount of fuel going down the highway, but more and more, RVs are using the sun’s energy once parked, and some owners think in the long run, the solar-powered RV ends up using a lot less than driving from hotel to hotel. And the Banningers say that once they’re boondocked in the desert, with their solar panels catching the sun’s free rays, life is good.
Some teachers are struggling with teaching evolution because some disagree on religious grounds. (Photo by Elliot Jordan)

Science teachers in high schools and middle schools are on the front lines of the culture wars. Conservative Christians and others are confronting them about teaching evolution in the classroom. At the same time, teachers are learning about the growing body of evidence that supports the theory of evolution. The Great Lakes Radio Consortium’s Julie Grant reports:
Some science teachers got a chance to attend a major science conference recently. Researchers from around the world were in Akron, Ohio to present findings and learn about advances in evolutionary biology. The conference was organized by people studying the dramatic transition whales made when they moved from the land to the water.
It’s only been a few years since Ohio even allowed the concept of evolution into the state’s high school academic standards. Those standards are the basis for the state graduation test that students must pass to get a diploma.
Even though it’s part of the state curriculum, many science teachers get the brunt of complaints from students and parents who oppose teaching evolutionary theory.
THOMAS: “I did have a student come to me and literally say, ‘I cannot sit in this classroom and listen to what you’re talking about.’ And I said, ‘Why not?’ And she said, ‘Well, I’m a Christian, I can’t listen to this.’ I said, ‘Well, I’m a Christian too, so where’s the problem?’”
GRABERT: “Well, I’ve had a number whose fathers are ministers come in and tell me how I need to teach the class, and I have to talk about creationism and I just share with them what we have to teach and how the curriculum is.”
STONE: “There’s a point when you just sort of have to tell the kids, This is what you need to know to pass the test to get out of high school. So, sit down, listen, learn the facts you need to know. I’m not saying you have to believe what I say, but this is what the state says you need to know to get out of high school.”
These are teachers from rural, suburban, and city school districts but they are all dealing with this issue. They try to stay up to date on new scientific evidence to defend their classroom lessons. That’s part of the reason they’re at this science conference.
(Sound of lecture)
This day’s activities are geared toward schoolteachers. The world’s top researchers on whale evolution are explaining their latest findings. Ann Sowd teaches honors biology at Hoover High School in North Canton, Ohio.
“It’s important to be at workshops like this so that you can, as a high school teacher, be really accurate with your teachings and understand what the evidence for evolution is and why it’s really- what we do know about how organisms change over time. Because the worst thing that can happen is you’re inaccurate and then someone comes with the opposing argument and you don’t know what you’re talking about.”
The teachers are hearing from scientists from all kinds of disciplines from anatomy, to functional morphology, to geo-chemistry. The scientists are showing how their discoveries and analyses fit together and provide a picture of the evolution of the whale as it moved from land back to the ocean.
But one leading researcher says the schoolteachers need more than just new scientific research to defend their lessons in the classroom. Howard University anatomist Daryl Domning says students who question evolutionary evidence are often looking for answers that lie beyond the realm of science. But Domning says teachers often respond with the latest research and recent fossil discoveries.
“And then they’re amazed that it doesn’t convince them. Because even though they’re raising questions about scientific evidence, they’re really not passionate about the scientific evidence. They’re passionate about ‘what is the meaning of my existence?’ and until you get down to that level and surface those concerns and show that hey, evolution doesn’t mean there’s no meaning to your existence, on the contrary, it can mean all these things, it means there’s more meaning then you thought there was maybe, only then is there a way of breaking through this pattern of talking past each other, which is what we’ve been doing for thirty years here.”
Domning says teachers can help students and parents understand that accepting the evidence of evolutionary theory doesn’t have to undermine religious faith.
He encourages teachers to tell students they can believe both at the same time, to point them to places where they can get more information, and to quickly get back to the science lesson.

The Eastern Eastern Massassauga Rattlesnake used to be found all over the Midwest. Now there’s only one state where the population is fairly healthy. But even there, it’s threatened by rapid development. A group of scientists is trying to protect the snake before all of its habitat is gone. The GLRC’s Chris McCarus reports:
(Sound of snake rattling)
A team of veterinarians and researchers is pulling an Eastern Massasauga Rattlesnake from a bag. They put the snake on an operating table. Then the doctor snips open the skin.
“Okay, so I’m into the abdominal cavity.”
She’s putting a radio transmitter the size of a AA battery into the snake’s belly. This will allow them to track the snake’s movement in the wild for the next two years.
Kristin Wildman is a graduate student at Michigan State University. She catches and tracks the snakes. She’s involved in a project with federal, state and university biologists. They’re trying to protect the Massasauga.
She thinks of the snakes as being much like herself. She identifies with their personalities. Wildman says these snakes are just modest. They don’t like to attract attention and don’t like to hurt anybody.
“Like with this snake, she’s one of the bitier snakes I have in this study. And she only strikes the tongs – the snake tongs – because I’m grabbing her with the snake tongs. It just kind of gives you an idea. They don’t really strike unless you’re messing with them, unless they have a really good reason to, or unless they’re harassed enough that they feel they need to.”
Although it would rather avoid you, if you’re bitten by a Massasauga Rattler, its venom can kill you.
But it can’t fight people destroying its habitat.
Mike DeCapita is with the U.S. Fish and Wildlife Service. He and other experts say rapid development is the snake’s biggest enemy. It’s not only destroying the snake’s habitat, it’s also destroying other wildlife habitat.
“The Massasauga is sort of an indicator species or a keystone species; perhaps that if we adjust so that we protect the needs of the Massasauga then all those species that use that same type of habitat also are protected.”
The onslaught of development has made the Eastern Massasauga Rattlesnake a candidate for the endangered species list, though it’s not on the list yet.
(Sound of hammering and cement mixing)
A new subdivision is being built in suburban Detroit. It’s just beyond the gate of a park where the research team came to study Massasauga habitat.
(Sound of people walking on a trail and talking)
Andy Hertz works for the State Department of Environmental Quality. He has the authority to refuse a building permit to anyone who could hurt Massasaugas.
“This is part of an effort of making us more aware of the habitat the Massasauga’s found in, so hopefully, we can direct developers and landowners to stay away from these more sensitive areas.”
In the winter, the Massasauga joins the frogs and turtles. They hibernate in marshes about two feet underground. Then, in spring and summer, they’ll seek higher ground for feeding. They can’t survive if they can’t move back and forth between their summer and wintering grounds. The research team has figured out this rule for minimizing damage to the snake’s habitat: don’t tamper with wetlands in winter nor the uplands in summer.
The team is focusing on Michigan to see why the population is the healthiest there. Then perhaps they can understand how to protect the rattlers in the rest of the Midwest where they’re nearly wiped out.
While she’s looking for more snakes, graduate student Kristin Wildman laughs about how a woman once called her to take a Massasauga away from the side of her house.
“We said, ‘Well, we’ll come out and we’ll move it for you.’ And we usually just move it down into the nearest wetland, down the hill. We pull in and she lives on Rattlesnake Drive. I didn’t expect to move out here and have all these rattlesnakes and stuff. It’s like, you live on Rattlesnake Drive. It’s called that for a reason.”
Wildman says when people come into conflict with wildlife, the wildlife almost always loses. If the Massasauga Rattler is going to survive it will take constant attention from all kinds of experts. They’ll have to stop developers from building over the snake’s habitat and threatening its existence.
