Researchers might have a partial solution to the problem
of beech bark disease. The disease has killed millions of beeches
in the Northeast and is advancing on the woodlands of the Midwest.
The Great Lakes Radio Consortium’s Tracy Samilton has this report:


Beech bark disease happens when an insect infests beech trees. Then the
trees are killed or crippled by an opportunistic fungus. Where the
disease has struck, researchers found one to five percent of the trees had
natural resistance to the insect.


Jennifer Cook is a USDA Forest Service researcher.Her experiments found that seeds from two resistant parent trees produced progeny that are also resistant. That could set the stage
for reforestation and even pro-active plantings.


“People can plant them before the disease gets there and
therefore lessen the impact on their forest lands.”


Cook says if you’ve got a big beautiful beech tree you want to save, you
can scrub the tree’s bark with insecticidal soap once a year. Of course
it would be impossible to scrub every beech tree in the forests.

At this time of year, one of the nation’s most exotic
birds is nesting, and many wildlife lovers are rejoicing. Once
close to extinction, the Eastern population of sandhill cranes
has grown dramatically. In fact, their numbers are so big that
they’re becoming a problem in some places – and there’s talk of
starting a hunting season for cranes. The Great Lakes Radio
Consortium’s Sandy Hausman has the story:


(Sound of marsh and birds)


It’s a cool spring morning, just before dawn. Brandon Krueger is watching a stretch of marshland along a country road in Central Wisconsin. Krueger works for the International Crane Foundation. He’s taking part in the annual Midwest crane count. Celebrating its thirtieth year, thousands of volunteers have fanned out across parts of Wisconsin, Michigan, Minnesota, Illinois and Iowa to look and listen for sandhill cranes.


“It’s a great sound to hear when you’re waking up. This is usually the earliest that I ever get up during the year. It’s a real struggle, but it can be worth it – for some of the things that you hear and the opportunity to see cranes.”


(Sound of crane call)


Krueger hears a breeding pair a half a mile away – exchanging what’s known as a unison call. The birds are big – up to five feet tall. A hundred years ago they made easy targets for hunters. In the 1930’s, naturalist Aldo Leopold lamented the loss of cranes – nearly hunted to extinction in Wisconsin. He knew of only 25 breeding pairs of sandhills in the state. But the federal government made it illegal to hunt cranes, and the state started working to restore bird habitat. Today, crane lovers celebrate an impressive comeback.


“I’ve talked with our leading field ecologist and he’s estimated upwards of forty-thousand sandhill cranes in the Midwest area.”


This year’s crane count is still being tallied, but Krueger heard nine birds and saw three flying by.


(Sound of cranes)


In the county next door, Troy Bartz claims to see many more birds than that on a daily basis.


“I’ll come home and it’s nothing for me to see two, three-hundred cranes in a field in one crack.”


Bartz has been farming for 13 years – growing corn, soy beans and alfalfa on nearly a hundred acres near Nina Creek.


(Sound of plow)


“Plants started disappearing out of the field with crane tracks right next to them. They go right down the row and they pull the shoots out of the ground and eat the kernels off the roots. I lose thousands of plants every year.”


The International Crane Foundation says damage in Wisconsin alone could total $100 million, and for family farmers, a year’s profit could be lost.


Bartz: “On the small acreage that I’m tilling, you can’t lose thousands of plants and not have some kind of an impact. That’s hundreds and hundreds of bushels I’m losing.”


Hausman: “And what’s the cash value on that?”


Bartz: “I figure anywhere between two to three-thousand dollars minimum every year.”


Hausman: “So what do you think the answer is?”


Bartz: “Shoot ‘em.”


Hausman: “Really?”


Bartz: “Yeah!”


There is some talk of having a hunting season for cranes, but that would require approval from the U.S. Fish and Wildlife Service, and many critics say the eastern population of sandhills is too small to permit hunting. The Wisconsin Department of Natural Resources says there are alternatives for farmers – machines called banger guns that make explosive sounds every few minutes. Troy Bartz’ neighbor, Mel Johnson, tried that, but found the birds quickly got used to the noise.


“The DNR warden brought the guns out. He said the best way is to mix a few regular shells in with it, he said, because it won’t scare ‘em away, the guns. He’s been taking them out for years, and he said they won’t scare any wildlife away – them guns.”


They’ve also tried scarecrows and colored ribbons but they didn’t work either. Farmers have had success with a product called Kernel Guard – a pesticide that made corn seeds taste bad to cranes, but this year the manufacturer stopped making it because one of its active ingredients can be toxic. Crane advocates are now asking the EPA to allow use of another chemical that’s already sprayed on golf courses to repel geese, but approval is not expected this year.


(Sound of cranes)


So crane lovers are keeping their fingers crossed – hoping farmers won’t be breaking the law by shooting the birds.

Most people associate Honda with cars and motorcycles. But the company has
an interesting sideline: as a cost-saving measure, they’ve been exporting
soybeans from the US to Japan. The Great Lakes Radio Consortium’s Nora
Flaherty has more:


Honda started exporting the beans as a way to reuse the huge cargo
containers that would arrive at the plant filled with auto parts. Instead of
sending them back empty, they wanted to fill the containers with something that
they could sell, and soy beans were a good fit. Joe Hannisik is the manager
of the plant, called Happy Ohio, where the beans are processed for shipping.


“We basically contract production with about 250 to 280 farmers in Ohio and
southern Michigan, for contract production, back to Happy Ohio, for processing and shipment of
soybeans primarily to Japan the majority of them.”


Honda only buys beans that haven’t been genetically modified, because that’s
what the Japanese prefer. And Honda pays farmers a higher price for their
beans than they’d get on the open market. Hannisik says that this can make a
difference when farmers are making decisions about whether to plant
genetically modified seeds.

Researchers in England have an idea for your old mobile phones – bury them and grow a
flower. The Great Lakes Radio Consortium’s Erin Toner explains:


Most people have one – if not several – cell phones they’ve outgrown. Some keep them
around for no good reason, some just throw them away, and some people actually recycle
them.


Kerry Kirwan at the University of Warwick in England wants to take that idea further.
He’s developing a biodegradable cell phone case that could be buried and would grow
into a flower when you’re ready to upgrade your phone.


“We thought it’d be a rather unique way of getting people to take responsibility of the
disposal of their mobile phones, but also, a way for moving a lot of plastic waste from the
waste stream so it didn’t have to be dealt with.”


Kirwan says he’d like to have the product on the market in a few years. He says the
phone cases would contain a wide range of flower seeds, based on what would grow best
in your climate.

Books can be powerful. Sometimes they can even change your life. As part of our ongoing
series on individual choices that impact the environment — “Your Choice; Your Planet” —
the Great Lakes Radio Consortium’s Curtis Gilbert brings us the story of one book that
changed his mother’s life…a book that so profoundly affected her that she felt compelled
to share its teachings with strangers. It wasn’t the Bible or the Koran… or “Chicken Soup
for the Soul.” And the part of his mother’s life that it changed is one so exceedingly private
that most people don’t even like to talk about it. He’ll explain:


There’s a sound — something familiar to everyone who lives in a Western, industrialized
country — but it’s a sound you’ll almost never hear at my mother’s house.


(sound of toilet flushing)


Five years ago, my mom turned off the to water to her toilet. She put a house plant on top
of the seat and opposite it built a five-gallon bucket in a box that took over all the duties
of its porcelain counterpart.


“Well I had seen ‘The Humanure Handbook’ in the FEDCO Seed catalog — and it just sort of
intrigued me. And I decided one year that I would read it since I was curious about it year after
year. And I read it and then I began to feel really bad every time I flushed the toilet.”


That’s because every time my mom flushed the toilet she was rendering undrinkable several
gallons of otherwise perfectly good water. And what’s more, she was whisking away valuable
nutrients that she could have just as easily returned to the earth.


That’s right… Humanure is a contraction consisting of two words: human and manure.


Here’s how it works: You use the humanure bucket in pretty much the same way you’d use a flush
toilet. Everything’s the same, except that instead of flushing when you’re done, there’s another
bucket right beside the humanure bucket and it’s filled with sawdust. You use a little cup to
scoop up some sawdust and then you just dump the sawdust in the humanure bucket when you’re
finished using it. That’s it. And the crazy thing, the thing that always surprises people when
I tell them about my mother’s humanure project is that it doesn’t smell bad.


“Anytime anything’s stinky in the humanure, you just cover it with sawdust and it doesn’t stink
anymore, except of course what is already in the air, which is like any toilet.”


Once a day my mom takes the bucket brimming with sawdust and humanure and dumps it into her
massive compost pile. There, it mingles with her kitchen scraps, weeds from the garden, and
just about every other bit of organic matter she can find… and in two years time the humanure
cooks down into dark, rich, fertile soil.


For the first couple of years, my mom was content just to operate her own humanure compost
heap and let her garden reap the benefits — but the more she did it the more of a true believer
she became. Strict adherence to the faith wasn’t enough for her anymore. She had to become a
missionary. She bought a case of Humanure Handbooks and set up a booth at an organic gardening
festival called Wild Gathering.


“And I think I sold one at that Wild Gathering. And then after that I was giving them away right
and left to my sisters and nieces and friends and whoever! And I used them all up and then this
last year I decided that not only was I going to get another box of Humanure Handbooks, I was
going to collect humanure at Wild Gathering!”


My mom knew she’d a lot of buckets for the project, so went door to door at the businesses
in town. She didn’t say what she needed them for, and luckily they didn’t ask. She collected eight
buckets full in all — not quite the payload she was hoping for. Attendance at Wild Gathering was
pretty low that year, due to rain, but relatively speaking, sales of the Humanure Handbook were
way up.


“I sold more at this last Wild Gathering. I think I sold five or six. And I gave one away for
Christmas this year to Natasha, who had been having plumbing problems. And I started my spiel and
she was really quite interested. And, I think we may have a convert there before long.”


Conversion. The ultimate goal of any evangelist. My mom admits that she doesn’t know of anyone
she’s actually brought into the fold — but she likes to think she’s planting seeds. Just
introducing people to the idea that there’s a alternative to flush toilets, she says, is a huge
step forward.


“This is really a shocking idea to a lot of people and a lot of people who come to the house will
not use it. I have to make the water toilet available to them.”


My grandmother won’t use it. Neither will my mom’s friend, Rochelle. And then there’s my
girlfriend, Kelsey. Last summer the two of us spent several days at my mom’s house in Maine
before taking a road trip back to where we live in Minnesota. After quietly weighing the
ramifications of sawdust versus water toilets, Kelsey finally decided to brave the humanure…
well, sort of.


Curtis: “So you used it for some things, but you’ve told me before that there were some things
that you couldn’t bring yourself to do.”


(laughing)


Kelsey: “No, I couldn’t. I did not have a bowel movement during our entire visit to your
house, over the course of four days.”


I’d like to think that Kelsey’s physical inability to make full use of the sawdust toilet
was an anomaly, that most people would have no problem going to the bathroom at my mom’s house
in Maine… But I doubt that’s the case. And that’s not the only reason I’m a little skeptical about
my mom’s vision of a world humanure revolution.


Curtis: “It occurs to me, and I’m about 100 pages into the book at this point, that this is
all well and good for people living in rural areas, but I live in a city. Where am I going to
put a compost heap?”


Mom: “You know, there could be chutes in buildings. There would have to be temporary storage.
Trucks would come in and take it out. Great huge compost piles would be built and it would work
down very… I think that where there’s a will, there’s a way.”


I’ll admit it; I’m still skeptical. I mean I believe in humanure, sure. But I also haven’t
put a house plant on top of the toilet in my big city apartment…and I probably never will.
Call me a summer soldier in the humanure revolution if you will, but when I go home to my
Mom’s next Christmas, I’ll be flushing with sawdust and I’ll be proud.

Modified Crops Swap Genes With Weeds

Genetically modified crops are planted throughout the Midwest, but some scientists are concerned genes from these crops could escape and work their way into weedy plants. With these genes, weeds could become more vigorous and harder to kill. New research shows this can happen between closely related crops and weeds.

Genetically modified crops are planted throughout the Midwest, but some scientists are
concerned genes from these crops could escape and work their way into weedy plants. With
these genes, weeds could become more vigorous and harder to kill. New research shows this can
happen between closely related crops and weeds. The Great Lakes Radio Consortium’s Cristina
Rumbaitis-del Rio prepared this report:


Genetically modified crops have been around for quite a while. In the U.S. last year more than 88
million acres were planted with genetically modified soybean, corn, cotton and other crops. Some
of these plants are engineered to be more resistant to herbicides, making it easier for farmers to
get rid of weeds without damaging their crop. Others are engineered to resist plant-eating insects.


But some scientists worry about the ecological effects of these crops. Allison Snow is a professor
of ecology at Ohio State University. She studies genetically modified sunflowers. Snow says she
got involved in this research when genetically modified crops were first being introduced because
she was afraid no one else was looking at the environmental effects of these crops.


“It was kind out of a fear factor for me of wanting to make sure that someone was watching to see
what the environmental effects might be.”


The sunflowers Snow studies have a gene added to them, which produces an organic insecticide
that kills insects feeding on the plants.


According to Snow, the problem with these pesticide-producing sunflowers is the insect-killing
gene can be transferred from crop sunflowers to their weedy cousins, which are often growing on
the edges of fields. Bees, flies and other insects can transfer the gene to the weeds by cross-
pollinating the plants, which are close relatives. Snow’s research shows once the gene gets into
the weed population, the weeds become insect-resistant as well.


“The new gene worked really, really well in the weeds. It protected them from the insects. And
because they were protected, they had more energy to devote to making seeds.”


Snow says the most startling result was the number of seeds these weeds were making.


“In one of our study sites, they made 55% percent more seeds per plant – just because of one
gene. Which is kind of unheard of. We’ve never seen a result like that – where one gene would
cause the whole population to suddenly start making 55% more seeds.”


The gene might make weeding a more difficult task, but Snow says she wouldn’t quite call them
“super weeds,” a term some environmentalists have used.


“We might see that the weedy sunflowers become worse weeds, I wouldn’t call them super
weeds, because to me that would imply that they have many different features instead of just one
that causes them to make more seeds. But I could imagine in the future there might be enough
traits out there that could turn a regular weed into something much more difficult to control – like
really would be a super weed.”


Snow says she will have to do more research to see if the extra seeds made by the weeds will turn
into more weeds and hardier weeds in farmer’s fields.


But, she might not be able to finish her research on sunflowers because the companies that make
the crop have decided not to renew her funding and won’t give her access to the sunflowers or the
genes.


“It was all about stewardship and responsibility.”


Doyle Karr is a spokesperson for pioneer hi bred, one of the companies which makes the
sunflowers. He says the company realized a few years ago there wasn’t enough demand for the
product to justify commercially producing it. As a result, he says, the company couldn’t continue
funding sunflower research, and doesn’t want to be held responsible for keeping the gene safe
while the research is being conducted.


It’s an issue of a biotech trait that we are not pursuing and not bringing to the market, and if we’re
not bringing it to the market, we can’t justify taking the responsibility of having that trait out
being worked with, with a third party.”


While some academic researchers argue the universities take on legal liability when they work
with genetically modified plants, Karr says the university’s liability is often limited by state law.
He says the company is ultimately held responsible if only by the court of public opinion.


“Should something happen with this gene that was not expected or a mistake happened – that
would ultimately come back to those who initially made the gene available.”


While this issue remains unresolved, Snow is continuing her research. Genetically modified
sunflowers are not the only crop to study. Snow is now working in Vietnam where weedy species
of rice grow naturally, and where genetically modified rice might be introduced in coming years.
She’s concerned the traits of the genetically altered rice might be transferred to the wild species
of rice, just as happened with the sunflowers.

Bug-Eating Birds Avoid Development

Researchers have found that building housing along lakeshores affects the kinds
of birds drawn to the area. The Great Lakes Radio Consortium’s Lester Graham reports:


Researchers have been looking at the differences between populations of birds along a lakeshore where houses have been built and where they’ve not. Alec Lindsay is a University of Michigan doctoral student who’s been working with the Wisconsin Department of Natural Resources, studying the birds…


“What we found is that the birds that feed on insects were found less frequently on lakes
that had significant shoreline development than lakes that were undeveloped. And on the other hand, birds that feed on seeds which are not normally associated with these sorts of habitats were found more frequently on developed lakes than undeveloped lakes.”


So, lakeshore housing developments might be discouraging the kinds of birds that eat mosquitoes and keep down other insect pests. Conservation officials suggest homeowners should plant more native shrubs and grasses to encourage the bug-eating birds to stay.


For the Great Lakes Radio Consortium, this is Lester Graham.

Commentary – Changing Our Genetic Future

Last week (week of April 3rd) a report released by the National
Academy of Sciences stated that it was not aware of any evidence that genetically modified foods are unsafe to eat. This is just the latest
news concerning this controversial issue. But Great Lakes Radio Consortium commentator Suzanne Elston wonders if we’re not making the entire issue too complicated:

Seed Industry Growing in Foreign Markets

The global marketplace is growing, with many industries enjoying theadvantages of free trade agreements that give them easier access toforeign consumers. But seed businesses still face tight regulationswhen it comes to crossing borders, and some in the industry say therestrictions should be loosened up. But if that happens, there may bean environmental price to pay. The Great Lakes Radio Consortium’s WendyNelson reports:
