Scientists who monitor pollutants in rain and snow in the U.S. and Great Lakes are offering their monitoring network to be used in the event of a wide scale bioterrorist attack. The Great Lakes Radio Consortium’s David Sommerstein has more.


The National Atmospheric Deposition Program is best known for its early detection of acid rain in the 1970s. It has a network of over 200 sites that measure chemicals like sulfur dioxides and mercury in precipitation. But coordinator Van Bowersox says the network could also be used in the case of an environmental emergency to trace things like anthrax spore.


“To help track perhaps the source of the material or perhaps just how wide dispersed the material may be. So this would be, for example, for a widespread release of a bioterrorism agent over a broad area.”


Bowersox says the samples of such agents would be sent to a special laboratory for analysis.


The idea wouldn’t be an unprecedented use for the network. The NADP surveyed the nation’s atmosphere for nucleotides following the Chernobyl nuclear disaster. It also measured the amount of particles in the air after the eruption of Mount St. Helens.

RESCUING FARMS WITH ‘AGRI-TAINMENT’

According to the food policy group Oxfam-America, more than 300,000 small farms have gone out of business in America over the last 20 years alone. Falling prices, imported produce and encroaching suburbs have all taken their toll on the family farm. But some farmers are finding new ways to keep their land and their lifestyles intact. More than a dozen of them in the Great Lakes states and southern Ontario are doing it by marketing their farms as a great place to visit.

According to the food policy group Oxfam-America, more than 300-thousand small farms have gone out of business in America over the last 20 years alone. Falling prices, imported produce and encroaching suburbs have all taken their toll on the family farm. But some farmers are finding new ways to keep their land and their lifestyles intact. More than a dozen of them in the Great Lakes states and southern Ontario are doing it by marketing their farms as a great place to visit. The Great Lakes Radio Consortium’s Bud Lowell has more from Hilton, New York:


“We all love the outdoors. It’s fun it’s something we can all relax at. Its not far from where we live and we love doing it.”


Brian Camp is in the middle of a 15 acre cornfield with his family and friends. They’re more than half-a-dozen people who drove to this farm in the Town of Hilton. They’re not farmers. They’re here to have a good time wandering through a maze:


“It’s an interactive game right in the middle of mother nature. It’s a 15 acre cornfield that we carved an intricate pattern into.”


Pat Zarpentine and her husband have run Zarpentine farms and its apple orchards for the last 25 years. This year, they’ve been trying out one of the newest tools small farmers are using to keep their land in the family. It’s called “agri-tainment” – packaging a visit to a farm as an experience that people will pay to share.


According to the North American Farmers Direct Marketing Association, more than 400 farms in the United States and Canada are making money by turning at least part of their land into entertainment ventures. Charles Touchette is the association’s Executive Director:


“This is becoming very big. Especially in what we call direct farm marketing, where the people are encouraged to come to the farm directly or the farmer.”


The fall hayride at Zarpentine Farms circles land that’s been in the family since 1832. But today, the farm is under pressure from the expanding Rochester, New York suburbs. Foundations are being dug for new homes just a few hundred yards up the road.


Pat Zarpentine says she and her husband have been watching the Town of Hilton change:


“We’ve seen other people having to sell off lots and parcels to survive. But we wanted to hold onto this. There’s such a strong tradition here.”


Zarpentine Farms already sells directly to customers through a farm market. Pat Zarpentine says the family wanted something that would draw new customers, but be in touch with their farming heritage.


Some farmers have put in paint ball courses or motocross tracks. But the Zarpentine family found their answer through a Utah-based company called “The Maize” – that designs and cuts intricate mazes in cornfields:


“We deliberately chose a big maze. We wanted it so we could have the design so you couldn’t see from one path to the next path.”


The corn towers above your head in the maze and the wind rustles the stalks. You walk on beaten-earth paths, and follow clues in the form of riddles that can help you find the exit.


After about 45 minutes in the maze, 14-year-old Owen Camp and Shannon Popowich say it’s a good way to spend a Saturday:


“It’s a good way to spend a day…like when you have all day!”


Zarpentine Farms charges seven dollars a head for adults to wander through the corn maze. Pat Zarpentine says her family’s first experiment with agri-tainment hasn’t actually turned a profit. But she says the visitors have definitely boosted sales at her farm market, and the maze attracts the right people:


“We get a lot of families. It’s a good outing. It’s wholesome, a great time for family to come together and spend quality time enjoying the outdoors in a setting where most families don’t ever get an opportunity.”


Agri-tainment is a growing business. Charles Touchette of the Farmers Direct Marketing Association says it’s driven by a desire for some Americans to get back to their roots:


“It used to be a generation or two ago everybody knew their grandparents farm. Now that’s not the case – that’s three and four generations ago. It’s unique, it’s a novelty to most Americans yet it’s something that’s still in our blood – seeing some green grass and enjoying a favorite season.”


Touchette says there are no reliable numbers yet on how many farms in the U.S. are offering “agri-tourism,” but it’s growing aggressively as people start to appreciate farms at a different level. For the Great Lakes Radio Consortium, I’m Bud Lowell.

Shipping Season Docks Early

Much of the shipping on the Great Lakes is expected to end early this year. The economy has reduced freighter traffic and some ships are already docked for the winter. The Great Lakes Radio Consortium’s Lester Graham explains:

Much of the shipping on the Great Lakes is expected to end early this year. The economy has reduced freighter traffic and some ships are already docked for the winter. The Great Lakes Radio Consortium’s Lester Graham reports.


The last couple of years, the shipping season has lasted longer. That’s because ships have been forced to carry lighter loads because of low water levels in the Great Lakes. And that meant more trips to carry the same tonnage. This year, though, some ships are tying up for the winter early. The slower economy has hit Great Lakes shipping, particularly those ships carrying raw materials for the steel industry. According to a report in the Toledo-Blade, iron ore mines have cut production and steel mills have produced significantly less steel. While only a handful of ships are berthed for the winter right now, a spokesperson for the Lake Carriers’ Association was quoted as saying they expect to see more early lay-ups. The shipping companies are hoping for an economic turnaround next year. For the Great Lakes Radio Consortium, this is Lester Graham.

Canadian Enviro Enforcement Criticized

An environmental lobby group in Canada says the Ontario Ministry of Environment watches industrial plants pollute the Great Lakes, but rarely enforces pollution laws. The Great Lakes Radio Consortium’s Lester Graham reports.


Between 1995 and 1999, polluters’ violated Ontario’s water pollution laws ten thousand times, but only eleven plants faced any penalties. Elaine McDonald is a staff scientist with the Sierra Legal Defense Fund, based in Toronto, which published a report on the findings. She says the problem started when the government cut the Ministry of Environment’s budget by about 40-percent:


“This resulted in lax enforcement in the field and– basically a policy of lax enforcement and therefore we saw this sudden increase in violations and very few charged being made.”


The Sierra Legal Defense Fund is calling on the Ontario government to crack down on Great Lakes polluters. The environmentalists say they do see signs of improvement, with more charges being filed in recent months against repeat pollution offenders.

Drilling Ban for Great Lakes

Congress has passed a measure banning drilling for oil or natural gas in the Great Lakes. The Great Lakes Radio Consortium’s Lester Graham has the details:

Transcript

Congress has passed a measure banning drilling for oil or natural gas in the Great Lakes. The Great Lakes Radio Consortium’s Lester Graham reports.


The legislation includes a two-year moratorium on new oil and gas drilling in or under the Great Lakes. US Senators Debbie Stabenow, a Democrat from Michigan and Peter Fitzgerald, a Republican from Illinois came up with the plan. They say the measure was needed in order to protect the waters of the Great Lakes from environmental damage. In Michigan, Governor John Engler denounced the measure. Engler is a long-standing supporter of drilling under the lakes for new energy sources. Susan Shafer is the governor’s press secretary.


“We’re concerned about the federal government coming in and telling us that Michigan and other Great Lakes states: ‘This is what you will do; you don’t have a choice on this.’ And, in the past there have been no federal statutes that have governed control over oil or natural gas in the bottomlands of the Great Lakes. And, so, that’s always been governed by state statute.”


Michigan was preparing to issue new drilling permits. Because of term limits, Engler leaves office at the end of next year. The candidates running for governor in Michigan all oppose new drilling permits. For the Great Lakes Radio Consortium, this is Lester Graham.

Smog Reduction Plan in Motion

Great Lakes states are slowly complying with new EPA rules designed to reduce smog. The Great Lakes Radio Consortium’s Jonathan Ahl explains:

Great Lakes states are slowly complying with new EPA rules designed to reduce smog. The Great Lakes Radio Consortium’s Jonathan Ahl reports:


The US EPA is requiring states to reduce emissions of Nitrogen Oxides, a main component in smog and ground level ozone. Coal-fired power plants and industrial boilers are the main producers of the pollutants. John Summerhays is an environmental scientist with the EPA’s Midwest Office. He says the reduction is an attempt to improve public health:


“The smog and ozone can cause a variety of health effects that are principally hard on the lungs. It can contribute to various lung diseases, so this is a big step forward for public health protection.”


Illinois and Indiana recently had their emission reduction plans approved by the Federal Government. Pennsylvania and New York have also been approved. Ohio and Michigan still have yet to submit reduction plans. The deadline for implementing the measures is 2004. For the Great Lakes Radio Consortium, I’m Jonathan Ahl.

Problem Geese Herded From Suburbia

Canada Geese are a familiar sight across the Midwest. Every fall the massive birds wind their way across the area as they migrate from Canada. But now, the region is also playing home to growing populations of resident geese. Instead of migrating, they stay near shopping centers and residential areas, where there’s a ready supply of food. For several years, one such population kept the residents of a Rochester, New York suburb feeling like they were in a state of siege. The geese chased pedestrians, caused traffic accidents, and left unpleasant signs of their presence almost everywhere. So town officials have hired an unusual business to encourage the geese to live somewhere else. The Great Lakes Radio Consortium’s Bud Lowell has more:

Canada Geese are a familiar sight across the Midwest. Every fall the massive birds wind their way across the area as they migrate from Canada. But now, the region is also playing home to growing populations of resident geese. Instead of migrating, they stay near shopping centers and residential areas, where there’s a ready supply of food. For several years, one such population kept the residents of a Rochester, New York suburb feeling like they were in a state of siege. The geese chased pedestrians, caused traffic accidents, and left unpleasant signs of their presence almost everywhere. So town officials have hired an unusual business to encourage the geese to live somewhere else. The Great Lakes Radio Consortium’s Bud Lowell has more.


“There’s hundreds of geese here. They come in the springtime, and after me being here about three or four times, I ended up right down to about 30 or 40 of them.”


Gordon Kornbau is at Westfall Town Park in Brighton, New York with his border collie, Arrow.


“You have to hit ‘em very hard in the beginning, just aggravate the heck out of them twice a day…. different times of the day. They get used to the fact that you’re not going away and they decide to nest somewhere else.”


Kornbau and Arrow are at this park to herd geese. There’s a 10-acre, roughly Y-shaped pond here…tucked up against an expressway. Neatly manicured lawns slope down to the water – and it turns out, that’s paradise for geese. They don’t like tall brush that conceals predators, so there are a lot of them here in the short grass.


But the geese don’t leave the park looking like paradise to humans.


“Look around here and notice all the…this whole blacktop last year was…from one end to the other, a square foot, you couldn’t walk. Same with the grass and stuff like that…Goose poop? Yeah…now we’ve got it down to a minimum. But we’ve got to keep after them. Now they’re done molting and the goslings are ready to fly so we’ve gotta get on them heavy again…. Arrow! C’mere…Arrow (whistles).”


Kornbau sends his collie to circle the pond. The geese know she’s coming. They splash, honking into the water as the dog runs toward them.


“All the way out – (whistles) – keep going!”


(Sound of geese honking)


“Basically, border collies are trained on sheep for years and years. Just transferring them from sheep over to geese isn’t that big a deal.”


Arrow, the Border collie, is half the geese herding process. Under his arm, Gordon Kornbau has been carrying a radio controlled, gas-powered model boat.


As the dog chases the geese into the water, he drops the boat into the pond


(Sound of model boat engine)


Kornbau steers the boat in circles. The annoyed geese take flight, and make for the far corner of the pond.


The Border collie rounds the pond and chases them back. Kornbau launches his boat again.


Every day he does this, a few more of the birds decide to leave for a quieter home someplace else.


“I send Arrow out and she’s scaring them all up…and people are standing there saying, ‘What are you doing – my kid’s having fun feeding the geese!’ Well –I’m sorry but – I have to be the bringer of bad news.”


This “geese herding” has been checked out by New York’s Department of Environmental Conservation. The DEC worked with Gordon Kornbau and the Town of Brighton, and gave the Town’s geese control program it’s OK.


Once in awhile, though, some people do get upset with Kornbau and Arrow. But he says they calm down once he shows them his business card.


A few passersby today seem intrigued by what he’s doing.


“What kind is it? –Border Collie – oh…so this is what a border collie looks like. Yeah…I’ve read about you guys in the paper. Having fun chasin’ those geese, huh?”


The Border collie, Arrow, knows the job is done. She’s back in the station wagon and ready for the next pond.


(Sound of door slamming)


“Nothing to it…good girl…. she’s the best!”


So how does somebody become a geese herder?


Gordon Kornbau was a mechanic at a golf course. He was looking for a business of his own, and that’s when he ran across a newspaper article about businesses in North Carolina and New Jersey that made money by herding geese.
He decided he could do the same thing. Now, Kornbau says he’s got the “best job he’s ever had.” No comment other than a lot of tail wagging from Arrow.

A commission that oversees water bodies shared by the U.S. and Canada is expanding its study of water levels in the Great Lakes. The Great Lakes Radio Consortium’s Karen Kelly reports.


The International Joint Commission recently announced it would review its regulation of water flowing in and out of Lake Superior. Any changes to Superior’s water flow could affect Lake Michigan and Lake Huron, as well. The commission is already studying similar changes in the regulation of Lake Ontario’s water. Officials say the studies were prompted by residents’ complaints about low water levels as well as the expected onset of climate change. Scientists predict this could also affect lake levels.


Peter Yee is the manager of the Great Lakes-St. Lawrence regulation office for Environment Canada.


“We have the opportunity to dialogue with the public so that we have a mutual understanding and appreciation of everybody’s needs and concerns, the benefits of regulation and also the limitations of regulation.”


Public hearings are scheduled to begin this fall.

Reviving an Ancient Fish

Sturgeon are one of the oldest vertebrates on earth. The giant fish have survived for more than 150 million years. But encroachment by humans, and in some cases poaching, have decimated the fish in many areas, including the Great Lakes. Now the sturgeon is on the brink of extinction. That’s why hundreds of scientists from around the world came to Oshkosh, Wisconsin recently. As the Great Lakes Radio Consortium’s Patty Murray reports, they came to witness a sturgeon success story:

Transcript

Sturgeon are one of the oldest vertebrates on earth. The giant fish have survived for more than one hundred fifty million years. But encroachments by humans, and in some cases, poaching, have decimated the fish in many areas including the Great Lakes. Now the sturgeon is near the brink of extinction. That’s why hundreds of scientists from around the world came to Oshkosh, Wisconsin recently. As the Great Lakes Radio Consortium’s Patty Murray reports, they came to witness a sturgeon success story.


The sturgeon is a really big fish. It can grow six feet long and weigh as much as two hundred pounds. Because of its size it faces few challenges from any other animal, except says Ron Bruch, from humans. Bruch is a fishery biologist with the Wisconsin Department of Natural Resources. He says most of the twenty-five species of sturgeon found around the world are in trouble, including those living in the lakes here. Years ago, he says the Great Lakes used to be full of sturgeon, but European settlers didn’t like them because they tore up fishing nets.


“Nets were very expensive back then they didn’t have the fancy nylon twine and all the other equipment we have today. So these big fish would get into the nets and rip them up so they didn’t like sturgeon. So they’d just kill the sturgeon, stack them up just to get rid of them. Then they found out the fish had caviar and there was a market for caviar.”


And that meant the sturgeon began facing another threat. Today, a pint of caviar can bring as much as six hundred dollars. That’s enough money to bring out poachers.


(Sound of boat on river)


So with the sturgeon population in rapid decline, scientists are eager to find ways to save those fish that remain. That’s why many of them came to Wisconsin this summer. While most of the sturgeon population in the Great Lakes has long since disappeared, some of the fish still survive here. So scientists gathered on the banks of the Wolf River to watch as DNR wardens plucked a few of the big fish out of the water.


(Natural sounds)


Wisconsin’s Lake sturgeon population is considered to be the healthiest on earth. Sturgeon experts’ say that is because of a strong, two-pronged effort by state officials. First, they have a monitoring program. Many of the sturgeon are fitted with radio monitoring chips to keep track of how each fish is growing and where it is living.


(Sound of measuring, checking for chips)


Then, to make sure the fish remain safe, game wardens regularly patrol for poachers, and volunteers guard riverbanks during spawning season. That’s when the fish are the most vulnerable because they float close to the surface and can be easily speared. But despite these efforts, the state’s sturgeon population still holds a threatened status. Most of the fish live in the Wisconsin’s inland lakes and rivers, while very few remain in Lake Michigan, and it’s that fact which prompted a very unusual donation. An Italian count recently visited Wisconsin and learned of the fish’s decline, so he has donated two thousand dollars to study how to strengthen the population. The count’s money will pay researchers to go into Lake Michigan and Green Bay to see how many fish are left. They’ll also look at what obstacles may block restocking efforts.


Scientists hope what they learn in Lake Michigan can be applied to the rest of the Great Lakes. The money may also help fish elsewhere in the world. The count sent a team of Italian scientists to spend a week shadowing Wisconsin researchers. Darren McKenzie is an English scientist working with the Italians on preserving sturgeon in the Po River.


“Well I hope we can learn a few things about the techniques they use particularly with radio tracking and population issues. Because probably the Wisconsin lake sturgeon rehabilitation management thing, whatever it is called, is one of the best in the world for monitoring sturgeon population.”


For many of the foreign scientists, the importance of the sturgeon was brought home by a visit to a Northern Wisconsin Indian Reservation.


“Welcome to the Menominee tribal reservation. The way we look at it you’re people of the sturgeon just like we are-concerned about the sturgeon.”


For the Menominee, the sturgeon is more than just unusual looking and good tasting. The tribe’s relationship with the sturgeon goes back ten thousand years to the Menominee creation story. Before European settlers came along, the tribe relied on the fish for food and fuel. Then, in the 1890’s a dam went up downstream that stopped the sturgeon from swimming to a traditional spawning ground on Menominee land. Back then, tribal historian David Grignon says, the federal government would not let the Indians go off the reservation to spear sturgeon.


“It was denying us of a resource that we’d had for centuries. You know it was probably like the buffalo to the plains…. a way of life was gone, wouldn’t return anymore.”


But the fish are returning, since they can’t swim to the reservation anymore, the tribe is trucking them in. It is a long-term project. Sturgeon don’t mate until they’re at least twenty-five years old, so some tribal members won’t live long enough to know if their efforts have paid off. But if the tribe’s project and others like it are successful, then humans may claim credit for saving the fish once almost pushed to extinction.

What Will Global Warming Bring?

Some scientists in the Great Lakes basin are looking at how global warming might be affecting the region, both today and long into the future. The Great Lakes Radio Consortium’s Lester Graham has the story:

Might be affecting the region, both today and long into the future. The
Great lakes radio consortium’s Lester graham reports.


Many researchers in a number of different fields are coming to the same basic conclusion: the earth is warming and it’s affecting the Great Lakes. So far, the effects have been difficult to track, unlike watching the day-to-day changes in the weather. Measuring climate change requires measurements over many decades, or better yet over centuries. There are only a few places where weather measurements have been taken over that long of a period. But, where they have, researchers are finding weather is becoming more chaotic and indications are that the long-term climate is warming.
Many climatologists believe that warming is due at least in part to greenhouse gases, that is, pollution in the upper atmosphere trapping more of the sun’s heat, much in the same way a greenhouse works.


Taylor Jarnigan is a research ecologist with the U-S Environmental Protection agency who’s been looking at one aspect of climate change. He’s been studying whether increasing amounts of lake effect snow from Lake Superior over the past century, especially the past 50 years, is evidence of a change in the temperature of the lake. Preliminary study suggests that the lake’s surface temperature is warming, and that causes more snow when cold air passes over it. But he says the amount of snow has varied widely from year to year.


“Some of this variability is certainly due –in my opinion– to an increasing volatile climate system itself. El niño and la niña are becoming more intense, so you have an increasing oscillation between, say, an usually warm summer followed by an unusually cold winter which tends to produce an unusually large amount of snow.”

The surface temperature of the lake has only been monitored for a few decades, while snowfall depths have been recorded for much longer. Jarnigan says, since there seems to be a direct correlation between the surface temperature of the lake and snowfall, he can calculate the temperature of the lake going back more than a century, and finds that Lake Superior is getting warmer.


When researchers find direct measurements that have been taken for more than a century, they feel fortunate. For example, John Magnuson with the University of Wisconsin has been reviewing the conclusions from the Intergovernmental Panel on Climate Change. That’s the international organization established by the United Nations to study global warming. As a part of that review, Magnuson has been looking over shipping and harbor records that date back 150 years or more to see if there’s evidence of global warming. One thing he’s learned is that lakes and streams aren’t iced over for as long as they once were.


“And in the last hundred-and-fifty years we’ve seen significant changes in lakes around the entire– lakes and streams around the entire northern hemisphere. The date of freezing on the average and the date of break up is changing by about six days per century.”


And Magnuson says that six day change on both ends of the freeze-thaw cycle mean that there’s nearly two weeks less ice coverage than a century ago.


That seems to bolster research at the National Oceanic and Atmospheric Administration’s Great Lakes Ecological Research Laboratory. Studies there indicate that over the last several years Great Lakes ice coverage on average is not as far ranging and doesn’t last as long as it did historically.


There’s no certain way to tell what might happen to the Great Lakes if the apparent warming trend continues.


But there are some ways to speculate. There are at least two computer models that try to estimate how much warmer the climate in the Great Lakes region might become by the year 2090. Based on those models, researchers have tried to figure out what that might mean for the area. Peter Sousounis was working at the University of Michigan at the time of that research. He says using either computer model it looks as though crops would produce more. Soybean yields could double. But other predictions are not as beneficial. It looks as though Great Lakes water levels would drop, probably about three feet more than they’ve already dropped, causing some problems for shipping. The study also found algae production would decrease by 10 to 20 percent. That’s important because algae provide the base for the Great Lakes’ food chain. Pine trees might also be all but eliminated from the region, and Sousounis says dangerously high ozone days might occur twice as often.


“Our findings indicate there are some potentially serious consequences in terms of reduced lake levels impacting shipping across the region, some serious economic impacts that if we don’t learn how to deal with these, there are going to be some serious changes in our lifestyles.”


Critics say the models can’t represent all of the variability in nature, so it’s difficult to be sure about any of the predictions. An adjustment here or there can lead to all kinds of alternative scenarios. Sousounis concedes more work needs to be done and more variables plugged into the models, but he’s convinced change will come; the degree of change is the only question.


These days, very few scientists argue against the studies that suggest the earth is warming. John Magnuson with the University of Wisconsin says a few DO argue that the change might merely be natural climate variability – that is, Mother Nature taking an interesting twist– and not necessarily a warm-up caused by manmade greenhouse gases.


“The skeptics, or the more cautious people, what they do when they look at that range of variation over the last thousand years, what they see is there is a signal in the warming that’s coming above the historic variation of climate. And, the climatologists of the world collectively feel there’s very strong evidence that warming is occurring, that greenhouse gases are a very significant part of that warming.”


Magnuson says most mainstream scientists agree climate change is happening, and even dramatic reductions in greenhouse gases won’t prevent some continued global warming over this century. But most say reducing pollution would slow the rise in temperatures and curtail the warming sooner. Only time will tell how that warming will change the Great Lakes region, and all of the researchers we talked to say in the meantime we’ll likely see more chaotic roller coaster type weather patterns as never before in recorded history.
