Some environmentalists are calling for a moratorium on growing genetically altered trees in
orchards and forests. The Great Lakes Radio Consortium’s Lester Graham reports:


Genetically modified crops have been in the fields for a number of years. Now, genetically
altered trees are being introduced. Fruit trees with genes spliced in to protect them from pests or
disease are becoming more common. And some forest trees are being genetically altered to make
them easier to process for paper.


Jim Diamond is with the Sierra Club. He says if these genetic traits are transferred into the wild,
it could mean biological contamination…


“When you put corporate-patented hacked genetic code out into the out-of-doors where it can
travel around, that genetic code can get into other related species and the way in which they can
interact and change nature is not understood at all.”


Orchards and paper companies say use of the genetically modified trees is safe. In some cases,
genetically modified trees have prevented the loss of entire fruit industries… and might be used
to restore some valuable trees back to the forests.


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

Study Finds Deer Reduce Forest Diversity

A soon-to-be-published study concludes that deer overpopulation is having a
devastating, long-term impact on forests. The study will come out next month in the
journal Ecological Applications. The Great Lakes Radio Consortium’s Cindi Deutschman-Ruiz reports:


The U.S. Forest Service study was conducted in Pennsylvania’s
Allegheny National Forest. It examined deer densities
ranging from 10 deer to 64 deer per square mile.
As deer increased, tree species declined.


Red maple, sugar maple, white ash, yellow poplar, and
cucumber trees were all adversely affected, and native yew has been practically eradicated in the forest.


Steve Horsley is the study’s co-author. He says the next step is to determine
whether the impact of deer on forests is as great in areas where there
are also housing developments and
farmland.


“Deer tend, for example, when agriculture is in the mix, to
spend their time eating alfalfa and corn,
which have more digestible energy than most of the
plants that you find in the woods.”


Horsely says in the meantime, deer populations must come down,
preferably to less than 20 per square mile. In the Allegheny National Forest, that would mean cutting the
population in half.

The Challenge of Managing Fragmented Forests

In the Great Lakes states, many of the original forests were cut down. They were cleared for homesteading, farming, and for the wood that fueled the age of steam. But over the past several decades, some of the forests have been growing back. Many of the new forests are confined to small patches or woodlots surrounded by farm fields. These woodlots are small havens for animals. But some foresters, biologists, and environmental groups are concerned that those forests are simply too small and too fragmented.

In the Great Lakes States, many of the original forests were cut down. They were cleared for
homesteading, farming, and for the wood that fueled the age of steam. But over the past several
decades, some of the forests have been growing back. Many of the new forests are confined to
small patches or woodlots surrounded by farm fields. These woodlots are small havens for many
animals. But some foresters, biologists, and environmental groups are concerned that those
forests are simply too small and too fragmented. The Great Lakes Radio Consortium’s Cristina
Rumbaitis(rum-bite-us)-del rio (del-rhee-o) prepared this report:


(Natural sounds – walking through leaves underneath) & Thomas Grubb talking:
“This little woodlot is large enough to house one pair of downy woodpeckers and one pair of
white breasted nuthatches.”


Thomas Grubb is a Biology Professor at Ohio State University. Instead of lecturing to a classroom
today, he’s strolling through a small, private woodlot next to a cornfield in central Ohio. This is
one of the study sites where he looks at how forest fragmentation affects woodland bird species.


He says just as in many areas of the Midwest, Ohio’s forests are highly fragmented because
instead of having the forest concentrated in one big area, the forests are carved up into small
patches, scattered throughout a largely agricultural landscape. While 90% of Ohio was covered
with forest before European settlement, now less than a third of the state is considered forested.
And according to Grubb, this part of Ohio has even less forest.


“This plot is about 3% forested and that’s not much forest. This landscape is probably as little
forested as any you’re likely to find.”


Grubb and his students are working with woodlot owners to see if the size of a woodlot affects
the number of birds living there and their survival. He says bird survival is better in larger
woodlots than in smaller ones.


“One of the things we think is happening in these small woodlots, these permanent resident birds
that are there all winter- they can’t get out of the wind, and so they have tremendously high
metabolic rates trying to stay warm.”


Smaller woodlots may be colder than larger ones because there’s fewer trees to block the wind.
Smaller woodlots also have less food for birds, and in the winter birds may starve trying to get
enough food to stay warm.


(Natural sounds of leaves and birds)


“Oh that’s a Carolina Wren.”


Forestry officials, scientists, and environmental groups agree forest fragmentation is one of the
most serious problems facing Ohio’s forests. Fragmentation is a problem for a number of reasons
beyond the fact that it represents a loss of forest habitat. According to Ohio State University
Ecologist, Ralph Boerner, the smaller a forest patch is, the fewer number of species that can live
there.


“The smaller a forest patch, the less diverse it is. And you particularly lose species that need
large areas in which to gather food.”


Boerner says smaller patches may also have a harder time recovering from disturbances – like an
insect outbreak or a tornado.


“We also believe there is a link between how diverse an ecosystem is and how stable it is in the face of disturbnace, so when you lose diversity there’s the potential to lose stability, lose the ability to bounce back
from disturbance.”


Breaking up the forest into patches also isolates animal and bird species that can’t or won’t cross
agricultural fields to get from one forest patch to another, and that means less genetic diversity
because they can’t mate with animals outside of their forest patch. So some woodlots are just too
small for certain species to survive.


Fragmentation also makes managing forest land more difficult. Most of Ohio’s forested land is
privately owned. Ohio Division of Forestry official, Tom Berger, says this makes managing
almost an impossible task.


Well, you’ll have 10 people and they’ll have 10 different views on how to manage it or what’s
valuable to them and they all have that right.”


Division of Forestry officials can give landowners advice, but they can’t tell a landowner what
their priorities should be. Berger says this often means neighboring patches of forest are managed
for completely different interests. Berger wishes he had more tools at his disposal to get land
owners to manage their land collectively.


“I wish we could put together some programs or some incentives, monies available through the
state or federal government that would really encourage landowners to work together to form
blocks or units that would be managed in the same way.”


Managing isn’t the only challenge. Berger says keeping the land at least partially forested is
becoming a problem as people choose to build homes in woodlots, particularly in areas near
cities.


“Not only is the woods scattered that we have fragmented, but a lot of them continue to
disappear too, especially in the urbanized areas in Columbus and around the state.”


Ohio State University Biologist, Thomas Grubb, says there are may reasons for protecting
woodlots, but his favorite reason is because it’s a pocket of nature in a sea of developed land.


“This is worth preserving just because it’s like it is and we ought to just leave it alone. This enriches our lives.”


The average woodlot size in Ohio is 20 acres, and it changes hands frequently – every seven years on average. The small size and the quick turnover make it nearly impossible for the state to
encourage owners to establish any kind of useful management practices. That means there’s little
to be done to help keep the forests from further deterioration.

In the wake of the World Summit on Sustainable Development in Johannesburg, South
Africa, there’s been a lot of talk about how to balance human needs with the health of the
planet. Ecologists have been trying to measure the impact of humans on the environment
for a number of years, with some sobering results. The Great Lake Radio Consortium’s Daniel Grossman went to the New
York Botanical Garden recently to gauge mankind’s ecological footprint.


[Rain forest sounds, misters, tinkling of water, rain falling on leaves]


To get a good sense of the impact humans are having on earth, you could travel for weeks
on intercontinental plane flights, river boats and desert jeeps. Or, as Columbia University
biologist, Stuart Pimm suggested, visit a botanical garden. There, under the glass and
ironwork of a conservatory, Pimm says you can see a resource that humans are
over-using – Earth’s most important resource, its plant-life.


“We’re sitting in the rain forest here at the New York Botanical Society. And it’s a riot of
green.”


Professor Pimm says here beneath the misters in the Tropical Rain Forest Gallery is a
good place to start a whirlwind tour of Earth’s greenery. The air is heavy with moisture
and sweet-smelling.


“Rain forests are some of the most productive parts of the planet. They grow extremely
quickly and they are therefore generating a lot of biological production.”


What Pimm calls biological production most of us know as plant growth. Biologists say
all this green growth in tropical forests and elsewhere on Earth is the foundation upon
which all life rests.


“Everything in our lives is dependent upon biological productivity – everything that we
eat, everything that our domestic animals eat.”


And everything that every other animal eats as well. In a recent book, Pimm painstakingly
tallies up how much biological productivity we use. He starts with the rain forest. In the
last 50 years, loggers and settlers have cut down 3 million square miles of lush tropical
forests. Much was cut down for subsistence agriculture, a purpose Pimm says it serves
poorly.


“Although the tropical forest looks rich and productive, it is a very special place. And
when you chop that forest down the areas that replace it often become very, very much
less productive.”


[Sound of walking around conservatory]


Pimm speaks of the toll on greenery of cities and roads and of land converted to farming
in temperate regions such as the U.S. Midwest. Then, trekking along the botanical
garden’s gravel paths, he leaves behind the tropical mists and steps into the dry heat of a
Southwestern desert. Deserts and other dry lands are not very productive, but they
account for a substantial fraction of Earth’s land surface. Most of it is grazed by flocks of
sheep, goats, camels and cattle, often causing severe damage to vegetation. When these
uses are added to the other impacts of humanity on earth’s bounty, the results are
surprisingly large.


“What silence has shown is that we are taking 2/5ths of the biological production on land,
a third from the oceans. And that of the world’s fresh water supply, we’re taking half.”


[Fade out sound of conservatory. Fade up sound of Texas frogs.]


[Sound of plane engines]


Frogs and toads croak out a spring mating ritual in a concrete drainage ditch. Nearby, a
pilot practices maneuvers in a small plane occasionally drowning out the amphibian
serenade. Living in culverts, sharing the night with droning engines, these wild animals
are never completely free of human influences. From his Stanford University office,
Professor Peter Vitousek says wherever you look, the din of human activities is
interrupting and crowding out other species. Vitousek made one of the first attempts to
tally the impact of people on plant productivity in 1985.


[Frogs fade out in time for Vitousek’s act]


“The message to me was that we are already having a huge impact on all the other species
because of our use of the production of Earth and the land surface of Earth. That’s not
something that our models predict for some time in the future or something that we’re
guessing at on the basis of fairly weak information. It’s something that we’re clearly
doing now. That’s already happening.”


Many ecologists say this conclusion is beyond doubt. What they can’t say is whether
human domination of so much of nature’s output is good or bad. University of Minnesota
Professor David Tilman says as a member of the human race himself, he appreciates the
comforts in clothing, shelter and food our lifestyles buy us. And he acknowledges that the
survival of our own species is probably not imperiled – at least for the moment – by the
destruction of others. Still, he wonders if someday we’ll regret today’s resource intensive
practices.


“I think the more relevant question to me is, ‘Are we doing this wisely?’ ‘Are we wisely
appropriating the resources of the world?’ So, my concern is that we live in a balanced
way – a way that is sustainable through generations – that we leave our children and
grandchildren the same kind of world that we have.”


An expert on the impacts of agriculture, Tilman says we’re using up more resources than
can be replaced. He says if we don’t grapple with these important issues now, by the time
the human population reaches eight to ten billion or so people later this century, it might
be too difficult for us to do enough to save the planet’s life as we know it today.

Earthworms Alter Forest Ecology

Most of us think of earthworms as beneficial creatures. Gardeners are always happy to spot a worm in the flowerbed because they add fertilizer to the soil. Many anglers say they’re the best thing for catching fish. But scientists are beginning to learn worms aren’t so friendly to Great Lakes forests.

Most of us think of earthworms as beneficial creatures. Gardeners are always happy to spot a
worm in the flowerbed because they add fertilizer to the soil. And many anglers say they’re the
best thing for catching fish. But scientists are beginning to learn worms aren’t so friendly to
Great Lakes forests. The Great Lakes Radio Consortium’s Stephanie Hemphill reports.


(fade up Girl Scouts)


This Girl Scout troop is learning about worms. Judy Gibbs is a naturalist at the Hartley Nature
Center in Duluth. She shows the girls how to coax worms out of the soil. They pour water laced
with powdered mustard into the worms’ burrows.


It irritates the worms and they come squiggling up by the hundreds.


“Pour it in. Wait a minute. Here it comes. It doesn’t like the mustard and it comes right up.
Look at this one (laughter). oh, there’s another one. Look at it go!” (shrieks)


On their walk through the woods, the girls look for dead leaves. There aren’t many. Judy Gibbs
explains why.


“Here’s a leaf stem that’s being pulled into this hole. Who’s doing this? Ants! No. Worms.
There’s big night crawlers. You know what a night crawler is? They grow straight down into the
ground, and they come up at night and pull leaves down into their burrows. And they eat the leaf
right off. That’s why we’re not finding any leaves.”


Worms eating leaves might seem natural, but it turns out these worms aren’t native to these
woods. The last glacier buried most of what is now the Great Lakes region. When it melted,
plants and animals returned to create a community of maples, pines, songbirds, and tender plants
growing on the forest floor, like trillium…but not earthworms.


Cindy Hale is a biologist who studies the native wildflowers that grow in northern hardwood
forests. She loves the spring bloomers that take root in the spongy layer of decaying leaves on
the forest floor. Trillium, bloodroot, solomon’s seal.


Hale says many of these plants are disappearing.


“Sites that forty years ago were carpets of trillium have been slowly over the last two decades
declining to almost nothing, and people were scratching their heads, trying to figure out just
what’s going on.”


Earthworm populations are thickest close to cities. But Hale says people bring worms with them
when they come to the woods.


At first, settlers carried them in, along with the animals and plants they brought from Europe or
the east coast. These days, worms are spread by people who drive in the woods – loggers, ATV
riders…


“But in particular, fishing bait is a huge way that worms get moved around in our region.
Because there’s so many lakes and so much fishing.”


Hale and her colleagues set up test plots along an advancing line of worms in the Chippewa
National Forest in central Minnesota. The worms crawl about three yards further into the forest
each year. Hale is studying how the soil and the plants have changed as the worms advance.


Worms eat the decaying leaves on the forest floor. They mix that organic matter into the mineral
soil beneath it. And in time, they can use up all the organic matter and leave only mineral soil
behind.


That means the plants that have evolved to take root in the leaves on top of the soil have lost their
home.


Hale says these changes could affect every plant and animal that lives in the woods. She says,
for instance, even birds have declined by nearly 50% in the last fourteen years.


“Because ovenbirds nest in that forest floor, so if you lose the forest floor, then you may well
affect ground-nesting birds such as that. So when you start thinking about it, the potential
ramifications across the ecosystem get really wild.”


Hale says one of the big challenges in studying this problem is that there’s been very little basic
research – like how many worms are there are and where.


To gather more information and to get more people involved, Hale created a web-based learning
program. She’s asking teachers from around the country to have their classes do worm counts
and other research. Hale plans to add their data to the web page.


In Minnesota, the Department of Natural Resources is working with interest groups to try to slow
the spread of worms. Next year’s fishing regulations will include instructions not to dump your
worms at the end of a day of fishing.

Struggling Farmers Turn to Logging

In some states in the Great Lakes region, it’s been a bad year for fruit
trees. Some orchard owners are facing a devastating year. They’re
trying to find some other source to bring in some money. One way
farmers are choosing might hurt the environment and future income
for the farmers. The Great Lakes Radio Consortium’s Lester Graham
reports:


Tart cherries are legendary in northwestern Michigan. There are cherry
festivals, cherry streets, and even some of the businesses are named in
honor of the surrounding cherry orchards.


But this year, the tart cherry crop was nearly wiped out.


(sounds of coffee shop)


On a recent Sunday morning at Barb’s Bakery in Northport, Michigan
the locals and the tourists gather for coffee and pastry. Paul Scott is
having a cup of coffee and looking through the newspaper. He’s a cherry
farmer who lives on the peninsula between Lake Michigan and Grand
Traverse Bay. He explains what happened this year to the cherry
trees…


“In early April, we had four or five days of exceptionally warm
weather. It got into the mid-80s and it pushed the vegetative growth of
the trees way past of where they should have been for that time of the
year. Subsequently, we had two devastating freezes, back-to-back, two
nights in a row.”


Compared to last year’s bumper crop, the tart cherry trees will only
produce about three-percent of the crop. Sweet cherry trees will do a
little better… with about 15 to 25-percent of the crop surviving. Scott
says farmers who still have to make their farm payments and survive
are looking for other ways to bring in some cash…

“And,
the first thing that — in a year like this — what your people do
is go look for an opportunity to sell timber if they really are jammed
and they have to have something, that’s what they’ll do.”


(truck sounds)


That’s exactly what Jim Von Holt thought about doing. Von Holt is a
fourth generation cherry farmer. As we drive on the bumpy dirt road
through his orchard, it’s hard to find a single cherry on the trees. We’re
headed to a 20-acre stand of timber, a small hardwood forest at the
back of his property…


“Maple’s predominant. Ash would be second. There’s
some cherry, beech, and a little poplin here. The maple’s what’s worth
the most.”


Von Holt says the trees here are high quality hardwoods. That could
mean some pretty good money…


“This year with absolutely, essentially no crop to sell, if
you wanted to bring the money in, this would be a good year to bring the
money in. So, yeah, it’s a money issue. I’ve always kind of looked at this
up here on this particular farm as this is just a little bit of an ace in the
hole. If times get tough — and times are tough — or get as bad as they are
this year, this was something we could come into and say ‘Now is the
time to go ahead and do this.'”


Von Holt hired a forester to help him determine which trees should be
cut now and which ones should be left standing to continue growing for
a future harvest and future income. The longer they grow, the more
valuable the trees can become.


Not everyone turns to a forester to help. The cherry farmers sometimes
just let the timber-buyer decide.


Rick Moore is the forester for the Grand Traverse and Leelanau
Conservation District. He says he encourages landowners to at least get
bids from more than one timber-buyer before agreeing to allow logging.


“Right now there are timber buyers who aware of the plight of
the cherry farmer. And there are people up here who are not so
reputable who are knocking on doors.”


And Moore says some of those loggers will take every tree that can be
harvested… especially the good maples… even if those trees should be
left standing for future harvests years down the road.


On top of that… timber-buyers are giving farmers much less for their
hardwood timber right now. Some hardwood prices have dropped to
nearly half of what they were just a few months ago. Timber buyers who
are cutting and buying trees now and then hold them until prices
rebound, could make a lot of money and leave the farmers with a lot
less income.


Jim Von Holt says that’s why he’s not cutting right now. By using a
forester to help ensure his timber stand will be around for future
selective cuts… he’s thinking about long-term income and the health of
the forest…


“So it has to be handled right. And, I’ve just watched too
many people, too many landowners in the area really take a bath on
letting just a logger come in and say ‘Hey, you know you need to cut this
place. All the 18-inch lumber needs to come out of here.’ And that’s
wrong. That’s just wrong.”


But, some of his neighbors are more worried about getting some quick
cash in a year when the tart cherry crop won’t bring in any money.
Some cherry farmers feel they just don’t have a choice.

Fighting Beech Bark Disease

Forestry experts throughout the Great Lakes have been experimenting with new ways to fight beech bark disease. The disease has already killed millions of beech trees in Pennsylvania, Ohio, Ontario and Michigan. The Great Lakes Radio Consortium’s Matt Shafer Powell has more…


Beech bark disease is actually a deadly tag-team combination of an insect that invades a tree and a fungus that finishes it off. Michigan State University entomologist Deb McCullough is one of several scientists trying to stop the spread of the disease in Michigan…


“What we’re going to see in the forest is gonna be something like Dutch Elm disease, the biggest, oldest beech trees are most vulnerable to this insect and to the disease, and as beech bark disease moves through the state, those are the ones that are going to die out first.”


McCullough says researchers have had some limited success with injecting pesticides into infected trees. And scrubbing the trees with soapy water seems to work too. But she says such methods simply aren’t practical when you’re dealing with the millions of beech trees that inhabit the region’s forests.

Gypsy Moth Continues Its Destruction

The gypsy moth caterpillar cut a wide-swath of destruction through some Great Lakes states this year. The caterpillar has been called one of the most destructive hardwood forest insect pests in the United States. The Great Lakes Radio Consortium’s Natalie Walston reports.


Agriculture officials in Great Lakes states have tried a variety of chemical methods to stop the spread of the gypsy moth. Still, it’s estimated the gypsy moth caterpillar destroyed a record forty-two thousand acres of trees in Ohio alone this year. The Ohio Department of Agriculture says that number has doubled from last year. Agriculture officials in New York State say the gypsy moth caterpillar feasted on fifty thousand trees this year. That’s compared to twenty-seven thousand last year. But, the state of Michigan got a break. Michigan Department of Natural Resources entomologist, Frank Sapio says the insects died from a virus before they could destroy trees, and he says the DNR released a natural fungus that worked with the virus to kill the caterpillars. Last year, though, the caterpillars were blamed for eating ninety-seven thousand acres of tree leaves in Michigan.

Repelling Christmas Tree Thieves

Evergreen trees grace forests, campuses, and lawns around the region. And much to the dismay of landscapers and gardeners, some of those trees disappear this time of year, stolen by someone who may not quite get the idea of Christmas cheer. But some universities have found a way to fight tree-rustlers. It involves a foul-smelling concoction that makes thieves regret taking a tree. The Great Lakes Radio Consortium’s Rebecca Williams has the recipe for this nasty, yet effective repellant:


About fifteen years ago, landscape managers at the University of Nebraska-Lincoln had a big problem. Tree thieves were cutting down the best conifers on campus. And the landscapers were getting calls from local residents, whose trees were also disappearing. Dennis Adams is a forester at the University of Nebraska.


“It’d be, you know, trees that have good Christmas tree form, so blue spruce, concolor fir, some of the pines – white pine, scotch pine.”


Some thieves were easy to track. Jeff Culbertson is a landscape manager at the university. He says students were stealing trees during Thanksgiving break… and they weren’t always perfect criminals…


“We’ve had instances where the students, I guess didn’t do a good job or didn’t think anybody cared, but you could find the dragged marks of the tree through the snow to their fraternity or dormitory or something like that so in those cases I think it was pretty easy for them to figure out where the tree went.”


Campus trees are worth hundreds of dollars, so the university was eager to find a solution. Dennis Adams discovered a solution… literally. He found the recipe in an old magazine… 1 part glycerine, 10 parts water, and 2 parts… fox urine.


Jeff Culbertson says the fox urine makes Christmas tree thieves think twice…


“It doesn’t really smell like skunk. Maybe like an extremely strong cat urine sort of smell. Or dog, something that’s very concentrated. But you know normally you’re not going to smell that. So it’s pretty pungent.”


Culbertson says since the University of Nebraska began spraying conifers in the 80s, they haven’t lost many trees. He sprays 50 to 100 Christmas-tree size evergreens each year. He used to wear a plastic spray suit, but now he just keeps the wind at his back.


“When I do the fox urine, I don’t have many volunteers that want to help me with that. So I take on upon myself to do it. They mostly stand away from me, and they probably don’t talk to me too much that day either.”


Culbertson says there is one problem with this technique… when it’s cold out, you don’t notice the smell. So he started adding a dye… he sprays blue or red stripes on the trees where he sprays the fox urine. He says it makes the trees that much less attractive, and serves as a warning. And each year, the university lets the local papers know they’re spraying fox urine again.


But if a thief still chops down a tree and drags it into his house … Culbertson says he won’t likely do it again.


“It would be a smell that you’d have a hard time getting rid of.”


Culbertson recommends the method to anyone with a lot of trees to protect. He says the repellant is pretty affordable, and normally wears off after the Christmas season. Most of the supplies, sometimes even fox urine, can be bought at a garden store.


“I use a small, 3 gallon bottle sprayer, typical sort of garden sprayer people would purchase at the hardware store, garden center… And I try to use hot water. The glycerin is very syrupy kind of like corn syrup. So it helps to loosen it up, heat it up and make it less thick. I mix it up, take it out, and just spray the trees by hand.”


Both Jeff Culbertson and Dennis Adams think thieves are just looking for a cheap tree. But Adams still finds the thefts a little unbelievable.


“I think people have to be pretty desperate to steal a tree for Christmas. That seems like it’s kind of in the anti-Christmas spirit to steal.” (Laughs)


Other campus managers, meanwhile…have cooked up their own people repellant. The University of Idaho adds a few ounces of skunk scent. It makes their mix even more memorable.

Keeping Resources Safe From Terrorism

Terrorism prevention experts say the attacks in New York and Washington, D.C., are reminders of how vulnerable the U.S. is.

Terrorism prevention experts say the attacks in New York City and Washington D.C. are reminders of how vulnerable the U.S. is. However, they say utilities and cities can take simple steps to safeguard natural resources such as forests and water sources against terrorist attacks. The Great Lakes Radio Consortium’s Lester Graham reports.


The terrorist attacks prompted alarm across the nation, and even people in areas that will likely never be the targets of terrorism are wondering aloud about their vulnerability.


Peter Beerings is the terrorism prevention coordinator for the city of Indianapolis, and speaks on the subject across the nation. Beering says because the U.S. has such great wealth well beyond its cities, it is vulnerable.


“We have vast expanses of natural resources, forests, parks, things that we consider to be natural treasures are just as easily national targets. But, it is important, I think, to remember that while we are vulnerable by virtue of our size, that this is not particularly something of interest other than to, perhaps, a single issue aggressor.”


By single issue aggressor, Beering means these areas aren’t likely to be the targets for international terrorists, but are occasionally targeted by fanatics for single causes. For example, forest fires have been ignited to protest development near wilderness areas, and an extortionist threatened to poison the water in Phoenix.


A small town about 50 miles southwest of Indianapolis also has been a target of a terrorist group. Dave Rollo sits on the Bloomington, Indiana Environmental Commission. Last year, environmental terrorists repeatedly hit Bloomington, destroying highway construction equipment, burning a house under construction in a sensitive watershed, and spiking trees in a nearby state forest to prevent logging.


“It really brought terrorism home to a small town such as
Bloomington when this sort of activity usually takes place elsewhere. So, I think that public officials, especially, had to rethink many things about how we– how Bloomington has to safeguard the community from these acts.”


Rollo says one thing is certain. Bloomington lost its complacency about the possibility of terrorism. After a period of fear and confusion, the city is now struggling with the proper security measures.


“How does one go about safeguarding a forest from deliberate arson, or how does one go about safeguarding a water supply the size of Lake Monroe which is the largest lake in Indiana. It’s an enormous challenge.”


And it’s a challenge that governments have been unwilling to talk about publicly, at least until now.


Jim Snyder is a researcher at the University of Michigan. At the direction of the President’s commission on critical infrastructure protection, he co-authorized a report on protecting water systems, possibly the most vulnerable target. But instead of getting information to the water purification plants across the nation, the government buried it, fearing that it might cause panic or give radical ideas.


“Some ten years ago we wrote a manual on how to secure water supplies for the EPA, but because they’re always worried about getting that notion into the public eye –which of course now any of these things are in the public eye– but they basically decided not to distribute that manual.”


Snyder says the manual outlined simple things, such as an emergency response plan, locking gates in sensitive areas and securing wells, and having guards on duty at water plants, things that would dissuade vandals or disgruntled employees. However, Snyder says, there’s little to prevent a determined terrorist with the right knowledge from poisoning a water system, undetected with contaminants small enough to fit in a backpack.


“It is certainly possible to put something in the water (which would go) which would be odorless, colorless, tasteless, uh, and not detected. And, your best indication that you have a problem are sick people or dead people.”


The terrorism prevention experts say no one can predict or prevent all acts of terrorism. But cities and utilities can make it more difficult, and that might be enough to dissuade some of these single-issue aggressors. Peter Beering in Indianapolis says natural resources have one more thing going for them.


“The good news is that these are comparatively uninteresting targets to an aggressor. And, as we learned, unfortunately, in New York and in Washington, that certainly there are much higher profile targets that are of much greater interest to people who are upset with the United States.”


Beering adds that should not be an excuse to ignore the risks to natural resources. He recommends every municipality assess its risks and take proper measures to secure its vulnerable areas.
