These ten threats to the Great Lakes are complicated. Researchers are finding new ways that nature reacts to them. For example, alien invasive species often compete for food and crowd out the native species. Once a foreign species takes control in an area, there’s not much anyone can do to get rid of them. But occasionally, a native species will bite back. The Great Lakes Radio Consortium’s Rebecca Williams has that story:

Invasive species have been a real problem for native species in the Great Lakes, but some native species are turning tails on the invaders. The Great Lakes Radio Consortium’s Lester Graham is our guide in exploring the series Ten Threats to the Great Lakes:


These ten threats to the Great Lakes are complicated. Researchers are finding new ways that nature reacts to them. For example, alien invasive species often compete for food and crowd out the native species. Once a foreign species takes control in an area, there’s not much anyone can do to get rid of them. But occasionally, a native species will bite back. The GLRC’s Rebecca Williams has that story:

These islands in Lake Erie seem like floating Gardens of Eden. They’re
popular with tourists. These islands also really appeal to a rare
snake.


“So there’s a dozen or so of them heading out into the water.”


Meet the Lake Erie water snake. It can grow up to four feet long. Snake expert
Rich King and I are watching a bunch of them swimming away, gray heads
peeking up like periscopes.


These snakes like the lake. They like hanging out in huge piles on docks
and boats, and Rich King’s discovered the snakes love to eat round gobies.


Gobies are invasive fish that are thought to have hitched a ride in the
ballast water of ocean-going ships from foreign ports. The gobies eat the
eggs of native fish such as smallmouth bass, and compete with other fish for
food and nest sites. As gobies have taken over the lake bottom, the native
fish the snakes used to eat are getting harder to find.


“What we’re seeing is that the gobies are apparently a very abundant food
source for the water snakes. Compared to the 1980’s and early 90’s when the
snakes were feeding exclusively on native fish or mudpuppies – the snakes
are now consuming over ninety percent of their prey items are round gobies.”


(Sound of walking over rocks and zebra mussels)


Today, Rich King and his students from Northern Illinois University are
prowling the beaches for snakes. They carry their catches in faded
pillowcases tied to their belt loops. This is the annual snake survey,
Nerodio. That’s Nerodia, the snake’s scientific name, and rodeo, as in
cowboy roundup.


The snake biologists don’t just look under rocks. They dive into the lake
for snakes. They sneak up on piles of snakes and then grab the whole
writhing mass.


The snakes bite. The researchers’ arms are covered in snakebites. The bites aren’t life threatening, but they’re really, really bloody. And then it comes to the job at hand. The biologists are going to force the snakes’ stomach contents out. They call it “barfing the snakes.”


“Some snakes are easier to puke versus others. The water snakes, for
example, they sometimes voluntarily just, bleagh, just puke it out when you
pick them up.”


PhD student Kristin Stanford promises me it’ll be a good show, and we’re in
luck: just down the road, Rich King makes his first prize catch of the day.


“I got a snake with a goby in it. See the bulge: that’s the head end of
the goby. I’m virtually sure it’s a goby. (laughs) So you just very gently work it
forward, and drop it into our ziplock bag. That’s a round
goby.”


King says the snakes are growing faster and getting fatter on their goby
diet. Bigger snakes are less vulnerable to predators, and bigger females
can have more babies.


The researchers are pretty happy about that. That’s because the water snakes
are listed as threatened under the Endangered Species Act. This is the
only place in the world these snakes are found. For years, people were
shooting snakes and bashing them with rocks. Their numbers were getting
dangerously low.


The snake biologists say they understand that a lot of people hate and fear
snakes, but they say now that the snakes are eating gobies, they’re
starting to get a little more popular, especially with fishermen.


(Sound of fisherman casting a spinning rod)


Mark Green fishes for smallmouth bass. Green says it seems like when he
sees more snakes, he has better luck.


“If they’re eating the gobies, that is a good thing. I mean, I’m sure they have their
place… just not at my place.” (laughs)


Green didn’t realize until today that the snakes like to hang out under the
metal rim of the pier, right by his feet. He cringes, but his curiosity
gets the better of him, and he peeks inside one of the pillowcases bulging
with snakes.


GREEN: “When they get ahold of you, do they let go pretty quick, or do they…”


STANFORD: “Typically, but every now and then you get what
I call a “chewer,” and they’ll just sit there and errr-errr-errrng.”


The people and snakes are starting to arrive at an uneasy truce, and the
snakes seem to be well on their way to recovery from all the feasting on
gobies.


The researchers are hoping to learn just how big a bite the snakes can take
out of the goby population, and if, in the long run, it’s good or bad for
water snakes to depend on a foreign fish.

Campaigning for Farmer Safety

Farming is one of the most dangerous occupations. Every year, thousand of farmers are seriously injured in the Great Lakes region, often because of carelessness or fatigue. And as the Great Lakes Radio Consortium’s Chris Lehman reports, sometimes farm work turns deadly:

Transcript

Farming is one of the most dangerous occupations. Every year, thousand of farmers are seriously injured in the Great Lakes Region, often because of carelessness or fatigue. The Great Lakes Radio Consortium’s Chris Lehman reports, sometimes farm work turns deadly.


“For any farmer listening, it makes me feel really dumb to do what I did”

What Illinois State Representative Dave Winters did was attempt to clean up a grain bin with his hands, instead of a broom. A slow-moving auger caught his glove on a wintry day last year and before he knew it, Winters was missing most of his little finger on his left hand.

“Any farmer is aware of the dangers of augers, and I certainly was. I was just careless, tired and not thinking”

When he’s not in the state capital of Springfield, the 49-year-old Winters grows corn, soybeans, and prairie grasses on his farm. After the accident, Winters decided to use his position as a public official to spread the word about farm safety. He says working alone, like he was, greatly increases a farmer’s risk.

“And you try to reach too far, you try to do things that you need help doing but there’s nobody available, so you get yourself into dangerous situations. The other problem is that if something does happen, in some instances farmers have lost their lives or have been severely injured because there wasn’t anybody there to turn off the equipment or to get help immediately”

Most family farms are too small to fall under federal occupational regulations that require a minimum of safety precautions. So sometimes, the simplest of safety measures may be overlooked. And that plus the presence of powerful machinery can make for a very dangerous work environment. Each year more than 700 farm-related deaths occur nationwide as well as tens of thousands of injuries requiring medical attention. These accidents cost farmers billions of dollars a year in medical bills and lost productivity.

The largest cause of farm deaths is tractor rollovers, and nearly two-thirds of tractor deaths involve people over the age of 60. University of Illinois Farm Safety Specialist Bob Aherin says this is probably due to slower reflexes among older farmers and their tendency to use outdated equipment. Most new farm implements offer greater protection to users, and Aherin says those safeguards have contributed to a general decline in farm deaths over the past twenty years. One area of particular concern on farms is children. Most farmers live and work in the same environment, and Aherin says it’s not unusual to have kids around.

“They’re either out doing work sometimes before they’re ready to some things and they are not prepared both physically, but more often it’s because they’re not old enough, they don’t have the mental processing skills to do some of the activities we ask them to do.”

The 1989 death of Iowa teenager Shaun Peterson in a farming accident led to the creation of a support group bearing his name. The Sharing Help Awareness United Network provides counseling to farm families who have lost a loved one of any age. Board member Kenneth Thu is a Northern Illinois University anthropology professor. He says farm accidents are especially tough on a family because the tragedy usually occurs very close to home . . . and that means they can’t get away from it. Even a serious injury can lead to a significant loss of income, and a lack of health insurance can be catastrophic. The result can be severe depression, and Thu says it’s sometimes tough to get help because many mental health professionals simply don’t understand the needs of rural farm families.

“Not recognizing the kind of living and work-structure that they live in. The kinds of stresses and strains they feel, particularly these days with so many farming couples working off the farm, the fact that the kinds of social networks that used to exist in rural areas are dwindling away quickly. And so people are often-times more isolated then they used to be”

And though it may be a stereotype, Thu says most farmers think they don’t need any help.

“Getting support services, counseling services to farmers is probably more difficult than providing those same services to people who live in urban settings, because there’s more of a reluctance for rural dwellers, particularly farmers, to get those kinds of services. They think of themselves as more rugged, more independent. So they’re less prone to access support services”

Even with a decline in farm deaths nationwide, those support services will continue to be needed. Farming trails only underground mining as the second deadliest occupation in the United States. For the Great Lakes Radio Consortium, I’m Chris Lehman.

Old Tires Hit the Gridiron

Great Lakes residents use more than two million tires a year, and many of them end up in a landfill. But one Illinois school has found an unusual way to use some of those tires. The Great Lakes Radio Consortium’s Chris Lehman has more:

Great Lakes residents use more than two million tires a year, and many of them end up in a landfill. But one Illinois school has found an unusual way to use some of those tires. And they’re saving on hospital costs as well. The Great Lakes Radio Consortium’s Chris Lehman has more.


(natural sound football practice, fade under quickly)


From beer cans to soda bottles, there are plenty of items that can be recycled at a typical football game. But at the 31-thousand seat Huskie Stadium at Northern Illinois University in DeKalb, Illinois, what is perhaps the largest recycling effort is in the field itself. More than 18-thousand ground-up tires are underneath the new surface of the playing field . . .mixed with sand; they provide a soft but durable base for all types of athletic events. The fake grass on top is similar to Astroturf, but project manager Norm Jenkins says this surface is better. He says the most important advantage is safety.


“It’s well documented over the last few years since these fields have been installed that the injury frequency goes way down in terms of ankle and knee injuries on this surface as opposed to the old Astroturf carpet. So it really simulates grass in that way. The other big advantage to this in our judgment is the appearance. Because really, as you sit in the stands at a Huskie football game–and even from the sidelines when you stand on that stuff–you’re convinced that the surface is grass. It looks, it appears just like a pristine grass playing surface”


The artificial turf at NIU is a brand called Field Turf. Jim Petrucelli is Vice-President of Turf USA, a Pittsburgh-based distributor of Field Turf. He says the scrap tires for the product are first washed with a high-pressure cleaning system similar to a car wash. But the tires aren’t run through grinder blades. That process is called ambient grinding because it takes place at room temperature. It tends to produce longer, rougher particles.


Instead, Petrucelli says the company cryogenically freezes the tires to temperatures below negative 80 degrees Fahrenheit.


“And then they drop them onto a hammer-mill. And the hammer-mill shatters them into pieces. And those pieces tend to have much flatter sides on them . . . that works much better in our system to prevent the rubber from migrating through the sand that it’s mixed with.”


Field Turf is used at several universities in the Great Lakes region, including the University of Cincinnati, Bucknell University in Pennsylvania, and at a University of Michigan field house. It’s also in use at dozens of high schools and public recreation facilities across the region, and has been installed in places as far away as Botswana and New Zealand.


Petrucelli says that at more than eight dollars a square foot, Field Turf is the Cadillac of artificial turf products. At Northern Illinois University, nearly one-third of the cost of installing the Field Turf was recovered through a variety of money-saving measures. The largest of these was a 200-thousand dollar grant from the Illinois Department of Commerce and Community Affairs. The money was awarded to the school for its use of the tires, which came from a salvage yard near Chicago. Robert Albanese is NIU’s Associate Vice President of Finance and Facilities.


“Every time you purchase a new tire there’s a fee that goes along with it. It goes to this fund for recycling the tires. And this process will only work, is if we use those recycled materials on the other end. And this is probably one of the bigger uses for recycled rubber that we’ve seen in the state of Illinois.”


NIU Director of Recycling Mary Crocker says the use of old tires in the Field Turf project wasn’t just about saving money.


“We’re interested in keeping the tires out the landfills. So this is probably the most comprehensive recycling program that you can find, where virtually everything has to do with recycling.”


(More football sound under)


The old Astroturf, which was removed to make way for the Field Turf, was also recycled. The university sold it for use as a soccer field overseas, earning an additional 29 thousand dollars for the school. For the Great Lakes Radio Consortium, I’m Chris Lehman.

Better Life in the Burbs?

  • New construction continues to spread into the countryside. A new study looks at the quality of life in these suburban developments.

People who move to the suburbs often say they’re escaping the stress of the city. But researchers are finding the suburbs cause a lot of stress for residents too, and the difference doesn’t seem to be as much about where you live as it is about how you live. The Great Lakes Radio Consortium’s Lester Graham reports:

People who move to the suburbs often say they’re escaping the stress of the city. But researchers are finding the suburbs cause a lot of stress for residents too. And, the difference doesn’t seem to be as much about where you live as it is about how you live. The Great Lakes Radio Consortium’s Lester Graham reports.


Ahhh, living in the suburbs, quiet tree lined streets, green lawns, and in the distance a glimpse of undisturbed woods along a creek or maybe farmland rolling off to the horizon. Across the Great Lakes region, the suburbs are picture perfect. Well, maybe not quite perfect.


A group of researchers has been spending a lot of time in the sprawling Chicago suburbs to see what draws people to the area, what they like, don’t like, from where they move and whether they intend to stay where they are, in the ‘burbs. What they’ve found is that living in the suburbs is not quite as stark or as bleak or as sterile as some of the popular press portrays it. But at the same time it’s not as blissful as the images in the brochures printed up by developers.


Charles Cappell is a sociologist at the Social Services Research Institute at Northern Illinois University. Since 1991 he’s been conducting surveys of people living in the suburbs. Mostly it’s been about why they live there. Usually the participants talk about their children, safety for their kids, nice schools, and nice green space for the family. But, recently Cappell and his team have been probing a little more deeply.


“In subsequent surveys, in 2000 for example, we did measure stress and we do know that suburbanites experience stress. They’re stressed from the demands of suburban life, some of the friction. But, in general, they report a fairly good quality of life.”


Of course, part of that quality of life is due to the surroundings. But after moving to the suburbs many people miss some of the more urban conveniences. And so as the housing developments sprout, the retailers are paving parking lots right behind them.


“This is one of the contradictions of suburban life: they value the quiet, green, suburban lawns and openness, and they crave the convenience of the shopping malls.”


But with that convenience comes the inconvenience of congested traffic on roads not designed to carry such huge volumes. While cities and counties spend untold millions of dollars widening old roads and building new ones, the suburbanites cope with the stresses of back-ups.


Rich Green is a geographer at Northern Illinois. He’s watched as the suburbs have spiraled out away from Chicago, causing an intricate and massive spider web of new roadways. Still, some politicians are calling for more and bigger roads in the suburbs. U.S. House Speaker Dennis Hastert is calling for an interstate to be built in his district that will create a new outer-belt for the Chicago metro area, some nearly 50 miles away from downtown. But Green says the Interstates in the Chicago area have simply created corridors of development. Instead of relieving traffic, some experts say the interstates around Chicago have simply given sprawl better access.


“Clearly, building these interstates hasn’t corrected some of the problems that people were hoping for. Usually, if you expand a highway, you bring more people.”


Traffic hassles are not the only stress suburbanites face. In fact, the more serious stressors have to do with the cost of living there. During the heady days of the stock market boom, people started building bigger and better houses out on one acre lots on the fringes of the ‘burbs. Now, because of the poor performance of the markets, those houses –sometimes derogatorily called ‘McMansions’– are extravagances that some suburbanites are struggling to afford. But if they want to live in the new Chicago suburbs, they don’t have much choice. Prices have skyrocketed and there’s very little in the way of affordable housing being built.


Dick Esseks is a retired professor who’s been doing research for the American Farmland Trust. The Trust is concerned about the loss of farmland due to development. Esseks says many of those who moved to the suburbs did so when times were good, but with the downturn in the economy, some of those people face forced early retirement.


“When they go from full-time workers to pensioned workers, can they find housing in the same community, stay in the same church, stay in the same synagogue, stay in other associations?”


Esseks says because many of the municipalities require large lots, have very high standards for construction, and agree to annex large subdivisions of ‘McMansions,’ they leave behind the chances for more affordable housing. Only the very well off can afford to live in many of the suburbs.


Still, even with the weight of big mortgages hanging over their heads, bad traffic congestion, and other stresses, researchers have found suburbanites seem to cope better on average than their counterparts in the city. Sociologist Charles Cappell says there’s a reason for that, and it has to do with who lives in the suburbs. Cappell says it’s established that married people and people with families tend to deal with stress better than single people. Older people are less stressed than young people, and the suburbs have a much greater ratio of traditional families with middle-aged parents than in the city.


“Some of the differences between quality of life between urban and suburban experiences can be attributed to the fact that urban places are more stressful or there are higher levels of stress because of these reasons. There’s more single people. They’re younger. But, the sources of stress, environmentally, may be different, but I think the bigger indicators of stress are your kind of social environment, your psychological space, how you cope, what kind of support you have and families in spite of their increased burdens on time, really do offer emotional support.”


So, people in the ‘burbs’, generally speaking, have a better support structure at home, and usually have the means to pay for a more comfortable, less stressful life to begin with. Cappell says getting out of the city and into the suburbs is not the answer to a stress-free life, but it just so happens there are a lot of people who live in the suburbs who are better able to cope with life’s stress.

Small Towns Invite Sprawl

  • Eleven million acres of prime farmland were lost to urban sprawl in a 15 year period. Some small cities are embracing the growth and helping developers circumvent so-called Smart Growth restrictions on sprawl.

Researchers have found that small towns hungry for new tax dollars are making it possible for developers to get around Smart Growth plans. Often the result is urban sprawl that paves over farmland and natural areas. The Great Lakes Radio Consortium’s Lester Graham has the story:

Researchers have found that small towns hungry for new tax dollars are making it possible for developers to get around Smart Growth Plans. Often the result is urban sprawl that paves over farmland and natural areas. The Great Lakes Radio Consortium’s Lester Graham reports.


Despite the best efforts of some politicians to slow down the pace of turning farmland into suburbia, the 2000 Census shows population growth is exploding at the edges of Metropolitan areas, and all those people need somewhere to live and shop. So, in the Midwest, often housing developments and shopping malls are built where corn or soybeans grew just the year before.


For example, Kane County, Illinois, as recently as the 1970’s was predominately farmland. Now with more and more people moving there, only about half the county is left for farming.


Randall Road cuts through the heart of the county, although housing developments and retail stores are starting to infringe on the country setting, on one side of the road you can still see rows of crops and pasture, and on the other side of Randall Road, it’s nearly solid shopping malls and subdivisions. But in the middle of all that development, there’s still one dairy farm. Mike Kenyon and his family still grow hay and corn, and milk cows here. But their fields are surrounded by three sprawling towns. Kenyon says Randall Road used to be the line where planners said urban sprawl would stop. They were so confident that they even said so in their planning document for the year 2020.


“And they drew a line in the county and they said ‘we want the growth to occur here and we want to maintain this as rural, as farms. Well, how did developers get around that? Well they go to a little village and they say ‘Well, we’ll put a big housing development over here. Please, annex us and this’ll be more revenue and they’ll even have a sewer system when we get done.’ So, that’s what happens; they kind of bribe the villages so they get around the 2020 plan.”


And that, Kenyon says, is what’s now happening on the other side of Randall Road where Kane County was supposed to remain rural. Kane County officials are trying to implement all kinds of programs to save the remaining farmland from urban sprawl, or at least keep urbanization to certain areas of the county. But at the town and village level, many local politicians see growth as nothing but good and are willing to expand their city limits to include developments. That’s because those developments help increase their tax revenue.


The story is not unique to the Chicago region. It’s being repeated throughout the Midwest and the Great Lakes, as well as across the United States.
So much so that millions, yes millions of acres of prime farmland in the U.S. have been lost in a little more than a decade. Rich Green is a geographer at Northern Illinois University. He’s been tracking the fringes of the ever-growing Chicago Metropolitan area. He’s been adding up just how much former cropland has been turned into suburban lawns and parking lots.


“What we found is this: the nation between 1982 and 1997, that’s a 15 year time period, lost about eleven million acres of prime farmland, cropland, to urban development.”


Green also found, perhaps coincidentally, that an identical amount of land, eleven million acres of rangeland was plowed up and put into crop production during the same period.


“What we’ve been looking at is losing the nation’s best farmland in places like Chicago and other metropolitan areas in the Midwest, and replacing it with marginal lands in the arid West which requires more inputs, particularly water, irrigation.”


Green says shifting farming to less productive and more environmentally damaging land might not be the intent of the small towns that want to grow, but that’s the apparent result.


Just off campus at Northern Illinois’ Social Sciences Research Institute, Director Harvey Smith says Midwest states such as Illinois should take the time to better learn and weigh the costs of continued urban sprawl.


“Economically, Illinois relies very, very heavily on its agriculture. And, it is also the case that a lot of the very rich farmland is in the northern tier of the state which is closest to the moving fringe of the suburbs.”


Many times government at a more regional level, such as at the county level, is struggling with balancing development and farmland preservation. Even though it’s something of a contradiction, Smith says the people who move to the suburbs’ fringes causing further urban sprawl, actually want to preserve some of the farmland.


“The fact is that many of the people who move into the suburbs, while they like the sort of scenic quality of a farm or two over the hill, aren’t in a position to stop the disappearance of the farms themselves. It requires cooperation between local and regional governmental agencies to make a real effort to protect these qualities that are likely to disappear if they don’t.”


For some towns, it’s too late to recover the rural character and small town charm they lost to development, but for those at the fringes of the sprawling large metro areas with adherence to Smart Growth planning, some planners believe there’s still the opportunity to preserve a little of the setting of the suburbs that drew so many people there in the first place.

SMALL TOWNS INVITE SPRAWL (Short Version)

  • Eleven million acres of prime farmland were lost to urban sprawl in a 15 year period. Some small cities are embracing the growth and helping developers circumvent so-called Smart Growth restrictions on sprawl.

The U.S. has lost millions of acres of productive farmland in the last decade to urban sprawl. Researchers say state and county officials are seeing Smart Growth plans circumvented by politicians in small cities. The Great Lakes Radio Consortium’s Lester Graham reports:

The US has lost millions of acres of productive farmland in the last decade to urban sprawl. Researchers say state and county officials are seeing smart growth plans circumvented by politicians in small cities. The Great Lakes Radio Consortium’s Lester Graham reports.


Most states have passed legislation or are looking at doing so to reduce urban sprawl. Even some counties are working to restrict development to certain areas. But often developers approach small cities, promising increased tax revenues and infrastructure if the town annexes large areas of surrounding land for the developers. Rich Green is a geographer at Northern Illinois University. He says some small town officials don’t see past their own city limits.


“And in some respects, they may overlook the regional concerns to benefit their own territory, developers, shopping malls, retailers, playing one municipality off the other in terms of getting the best deal to locate.”


And so long debated plans to manage growth become nothing more than lines on a map, while natural areas and farmland are replaced by subdivisions and parking lots. Green says that’s led to eleven million acres of prime farmland being taken out of production in the fertile Midwest and East in a 15 year period due to urban sprawl. For the Great Lakes Radio Consortium, this is Lester Graham.
