Researchers are looking at ways to use corn-based ethanol as a way to power hydrogen fuel cells. It would appear to be an environmentally friendly way to get into the hydrogen fuel economy. However, ethanol might not be as environmentally friendly as its proponents claim. Backed by the farm lobby and ag industries such as Archer Daniels Midland, ethanol has plenty of political support.

Researchers are looking at ways to use corn-based ethanol as a way to power hydrogen fuel cells.
It would appear to be an environmentally friendly way to get into the hydrogen fuel economy.
However, ethanol might not be as environmentally friendly as its proponents claim. Back by the
farm lobby and ag industry such as Archer Daniels Midland, ethanol has plenty of political
support. But some researchers say corn-based ethanol is a boondoggle. The Great Lakes Radio
Consortium’s Mary Stucky reports…


This reactor is in a laboratory at the University of Minnesota ticking as it converts ethanol into
hydrogen. Researchers here envision thousands of these inexpensive reactors in communities
across America using ethanol to create hydrogen, which would then be used in fuel cells to
generate electricity.


Lanny Schmidt, a Professor of Chemical Engineering, directs the team that created the reactor.


“We’re not claiming our process is the cure-all for the energy crisis or anything like that. But it’s
a potential step along the way. It makes a suggestion of a possible way to go.”


Hydrogen is usually extracted from fossil fuels in dirtier and more costly refineries.


Schmidt says it’s much better to make hydrogen from ethanol.


“It right now looks like probably the most promising liquid non-toxic energy carrier we can think
of if you want renewable fuels.”


Not so fast, says David Pimentel, an agricultural scientist at Cornell University. For years,
Pimentel has warned about what he calls the cost and efficiency and boondoggle of ethanol.
Pimentel says ethanol is a losing proposition.


“It takes 30-percent more energy, including oil and natural gas, primary those two resources to
produce ethanol. That means importing both oil and natural gas because we do not have a
sufficient amount of either one.”


Pimentel says most research on ethanol fails to account for all the energy needed to make the fuel,
such as energy used to make the tractors and irrigate crops. Adding insult to injury, says
Pimentel, ethanol relies on huge government subsidies going to farmers and agri-business.


“If ethanol is such a great fuel source, why are we subsidizing it with 2-billion dollars annually?
There’s big money, as you well know, and there’s politics involved. And the big money is leaking
some of that 2-billion dollars in subsidies to the politicians and good science, sound science,
cannot compete with big money and politics.”


Pimentel also points to environmental damage of growing corn – soil erosion, water pollution
from nitrogen fertilizer and air pollution associated with facilities that make ethanol. But
Pimentel has his detractors.


David Morris runs the Institute for Local Self Reliance in Minneapolis. Morris is not a scientist,
but he commissioned a study on ethanol. He says Pimentel relies on out-of-date figures and fails
to account for the fact that ethanol production is getting more efficient.


Morris’ findings – a gallon of ethanol contains more than twice the energy needed to produce it.
As for subsidies…


“There’s no doubt that if we did not provide a subsidy for ethanol it would not be competitive
with gasoline. But what we need to understand is that we also subsidize gasoline, and if you took
the percentage of the Pentagon budget, which is spent directly on maintaining access to Middle-
Eastern oil, and impose that at the pump, it would add 25- to 50-cents a gallon. At that point,
ethanol is competitive, under the assumption that you will not need a large military budget to
protect our access to Iowa corn.”


But more efficient than making ethanol from corn might be grass, or even weeds. David Morris
says that’s because you don’t have fertilize or irrigate those kinds of plants, the way you do corn.


“So if we’re talking about ethanol as a primary fuel to truly displace gasoline, we have to talk
about a more abundant feedstock. So instead of the corn kernel, it become the corn stock, or it
becomes fast-growing grasses, or it becomes trees, or sawdust or organic garbage. And then
you’re really talking about a carbohydrate economy.”


Pimentel scoffs at that idea.


“You’ve got the grind that material up, and then to release the sugars, you’ve got to use an acid,
and the yield is not as high. In fact, it would be 60-percent more energy using wood or grass
materials.”


While scientists and policy people debate whether ethanol is efficient or not, Lanny Schmidt and
his team soldier on in the lab undeterred in their efforts to use ethanol for fuel. Schmidt
understands some of Pimentels’s concerns, but he thinks scientists will find an answer, so ethanol
can be used efficiency enough to help power the new hydrogen economy.

Forests for Lumber or Wildlife?

  • Loggers and environmentalists fight continually over the use of national forests. Managers at many national forests around the country are developing new long-range plans. (Photo by Stephanie Hemphill)

Loggers and environmentalists are in a continual fight over the use of national forests. One of their battlegrounds is the long-range planning process. Every ten to fifteen years, the U.S. Forest Service designs a new plan for each national forest. Right now, several forests in the Northwoods are getting new plans. The Forest Service says it’s paying more attention to biodiversity, and wants to encourage more old growth forests. Critics on the environmental side say the new plans are just business as usual.

Loggers and environmentalists are in a continual fight over the use of
national forests. One of their battlegrounds is the long-range
planning process. Every ten to fifteen years, the U.S. Forest Service
designs a new plan for each national forest. Right now, several
forests in the Northwoods are getting new plans. The Forest Service
says it’s paying more attention to biodiversity, and wants to encourage
more old growth forests. Critics on the environmental side say the
new plans are just business as usual. Loggers say they still
can’t cut enough trees. The Great Lakes Radio Consortium’s Stephanie
Hemphill reports:


(sound of car door closing, footsteps in woods)


Jerry Birchem is a logger. He’s visiting one of his harvest sites on
land owned by St. Louis County, in northeastern Minnesota. The highest
quality wood will be turned into wooden dowels… other logs will go to a
lumber mill… the poorest quality will be turned into paper.


Birchem tries to get the highest possible value from each tree. He says in the last ten
years, the price of trees has tripled.


“We have to pay more for timber and the mills want to pay less, and we’re caught in the
middle of trying to survive in this business climate.”


Birchem likes buying timber from the county, like at this logging site. He hardly ever
cuts trees from the national forest anymore. He’d like to, but the Forest Service doesn’t
make much of its land available for logging. The agency says it doesn’t have enough staff
to do the environmental studies required before trees can be cut on federal land.


Jerry Birchem says loggers need the Forest Service to change that.


“You know there needs to be processes set in place so you know, it doesn’t take
so long to set up these timber sales. I mean, they’ve got to go through so
many analyses and so many appeals processes.”


Birchem says it should be harder for environmental groups to get in the way of timber
sales. But not everybody agrees with Birchem.


Clyde Hanson lives in Grand Marais, on the edge of Lake Superior. He’s an active
member of the Sierra Club.


He says it’s true loggers are taking less timber off federal lands in recent
years. But he says the Forest Service still isn’t protecting the truly special
places that deserve to be saved.


He says a place like Hog Creek should be designated a wilderness area, where no trees
can be cut.


(sound of creek, birds)


“Very unique mixture, we must be right at the transition between two types of forest.”


Red pine thrive here, along with jackpine and tamarack. It’s rough and swampy country,
far from roads. So far, loggers have left these trees alone.


But with the value of trees skyrocketing, Hanson says the place will be logged eventually.


Forest Service planners made note of the fact that the Hog Creek area is relatively
untouched by humans. They could have protected it, but they decided not to.


“And we think that’s a mistake, because this is our last chance to protect wilderness and
provide more wilderness for future generations. If we don’t do it now, eventually there’ll
be enough roads or enough logging going on in these places that by the next forest plan
it’ll be too late.”


But the Forest Service says it is moving to create more diversity in the
woods. It wants a forest more like what nature would produce if left
to her own devices.


The agency says it will reduce the amount of aspen in the forest. Aspen has been
encouraged, because it grows fast. When it’s cut, it grows back quickly, so loggers and
paper companies can make more money.


The trouble is, an aspen forest only offers habitat for some kinds of animals,
such as deer and grouse. Other animals, especially songbirds, need older trees to
live in.


So the Forest Service wants to create more variety in the woods, with more old trees than
there are now. But how to get the forest from here to there, is the problem.
Duane Lula is one of the Forest Service planners. He says fires and windstorms are nature’s way of producing
diverse forests. They sweep the woods periodically, killing big stands of older trees, and
preparing the soil for pines and other conifers. Jackpines, for instance, used to be more
common in the northwoods. Lula says the only practical way for man to mimic nature is
by cutting trees down.


“We can’t have those fires anymore just because people live here, there are private
homes here. There’s no way that we could replicate those fires. Timber management is one way of regenerating those jackpine stands in
lieu of having major fires.”


But Lula says the main purpose of timber cutting in the new plan is to move the forest
toward the diversity the agency wants, not to produce wood. And he says that shows the
Forest Service is looking at the woods in a new way.


“The previous plan tended to be very focused on how many acres you were going to
clearcut, how much timber you were going to produce, how much wildlife habitat you
were going to produce, and this one is trying to say, if we have this kind of desired
condition on the ground that we’re shooting for, then these other things will come from
that.”


As it does in the planning process in other national forests around the Great Lakes, the
Forest Service will adjust the plan after hearing from the public. Loggers,
environmentalists, and everyone else will have a chance to have their say. A final version
will be submitted to the Regional Forester in Milwaukee early next year. It could then
face a challenge in court.

Woman Fights Uphill Battle Against Water Diversion

In many communities, there are increasing demands for the limited supply of water. But people often feel there’s little they can do to protect that water from outside interests.

In many communities, there are increasing demands for the limited
supply of water. But people often feel there’s little they can do to protect that
water from outside interests. The Great Lakes Radio Consortium’s Karen Kelly reports on one
woman who fought to stop millions of gallons of water from being
drained from her local river:


(sound of crunching leaves)


It’s been a wet spring. But the leaves along the shore of the Tay River in Perth, Ontario
crunch beneath your feet.


Carol Dillon walks a path that was once submerged in water. She stops at a maple tree, and
points to a ring of greenish bark around its trunk.


“This is where the water comes to normally in the spring…
This was sort of the natural shore line, but the water has not
been this high, this would be the fourth year now.”


(sound of wind, crunching of leaves)


Carol Dillon and her husband, Mel, bought this piece of land in
1999. They came here to retire. Then, in the fall of that year, the Tay River dried up.


Four months later, they were shocked when a manufacturer applied
to take 1.2 million gallons of water out of the river every day.


“We simply looked out the window at this very dry river and
said, well how are they going to do that?”


Dillon soon found out they weren’t the only people asking that
question. Six thousand residents depend on the river for drinking water.
Another six thousand draw from wells in the river’s watershed. People worried there wouldn’t be
enough clean water during the dry season. And that wildlife would suffer.


(sound of truck)


An 18-wheeler pulls out of the OMYA plant in Perth, carrying a
load of calcium carbonate sludge. The Swiss company needs water to make the sludge, which
goes into products like paper and toothpaste.


They already draw about 400 thousand gallons out of the area’s
groundwater each day. But OMYA wanted to triple its water consumption so it could step
up production, with a promise of new jobs.


The public had 15 days to comment on the company’s plan.


As a consultant with the federal government, Dillon knew a bit
about bureaucracy. So she started helping out neighbors, who weren’t sure what they
could do.


“At one of the public meetings, a farmer stood up and said,
‘I’ve been a farmer on the Tay River for 40 years, but I don’t know
what to write in a letter to the minister.’ He said, ‘well, we have
to be careful with the water.’ And I said, ‘that’s your letter.'”


Dillon says she wanted to convince people that their voices do
matter. So she dropped off envelopes for them, faxed their letters, and
answered lots of questions. Before she knew it, she had kick-started a grassroots
movement.


“I was not a tree hugger in my life and I never was a
political person, either, but always believed in responsibility…
This is a democracy and when people have an opinion on something,
your government should hear it.”


People were inspired by Dillon. Jackie Seaton is one of the many who got involved.


“She simply spoke to the issue of water. If you’ve ever read
any of her memos or heard her speak at a council meeting, I mean
everybody can understand what’s she saying because it’s in the
plainest and simplest terms. And I must say that was very, very impressive.”


Typically, the ministry of environment receives fewer than 10
letters. But 283 townspeople wrote in to oppose the water taking.


Despite that, the ministry granted OMYA its permit.


The residents could appeal the decision to a quasi-judicial panel. But without money or a lawyer,
they decided it would be impossible.


Dillon, however, disagreed. She forged ahead on her own, and won the right to a hearing. She
relied on scientists who had retired in the community to help her prepare. It would be her word
against lawyers representing the company and the government.


(ambient sound)


Dillon pulls a thick plastic binder off a bookshelf that’s packed
with evidence used in the hearing.


She insists she wasn’t against the water taking per se. She just wanted the government to make a
decision based on good science. The company was granted the initial permit based in part on 75-
year-old data. Dillon argued more research needed to be done.


Over the past eight years, 46 community groups have challenged
decisions by the Ministry of the Environment.


No one had ever won – until now.


The panel granted the company just one third of the amount of
water it requested, with a potential for more in the future. And it directed the province to conduct
more research on the river.


“First, we were…it was unbelievable and then we were
ecstatic that it was all worth it.”


But the citizens’ celebrations were short-lived.


In April of this year, Ontario’s environment minister, Chris
Stockwell, reversed the tribunal decision and reinstated the full
permit. He cited new information that predicted the river would drop only
a few inches when the water was removed. The minister won’t comment on the outcome, other
than to say he stands by his decision.


But OMYA’s plant administrator, Larry Sparks, says the decision
was based on science. And while he recognizes that citizens have a right to question the
government, he says it shouldn’t come at the expense of business.


“And it’s very difficult to make
business decisions when you apply for a permit and have to wait three
years for approval and conclusion of the process. Our concern was not with the people, but rather
with the fact that the process was allowed to go on for three years.”


For Carol Dillon, the minister’s decision was a disappointing end to a
long struggle.


“You can have this two and a half year-long process and the
minister can just overturn it, politically, then what’s the point
of it all? So I’m back to where I started.”


(sounds by the river)


But Dillon hasn’t given up. Now she’s lobbying Ontario to adopt new standards for water use.
She doesn’t care if she has to write letters, battle lawyers or
lobby politicians – she just wants her community, and everyone in
Ontario, to have a say in the future of their water.

the process. The Great Lakes Radio Consortium’s Jenny Lawton reports:


At just over two pounds…”Harry Potter and the Order of the Phoenix” is one of
history’s heaviest childrens’ books. The book fills 768 pages with Harry’s adventures.


Vancouver-based Raincoast Books used about 1200 tons of paper free
from fiber from certain old and protected trees. All 915-thousand books are
printed on 100-percent post-consumer recycled paper.


Raincoast reports the printing saved 47-million liters of water, and nearly 30-thousand

Region Battles Emerald Ash Borer

An insect called the Emerald Ash Borer has already destroyed thousands of ash trees in Ontario
and Michigan…and in February, it was discovered invading the northwest corner of Ohio.
Agriculture officials there are trying to contain the bug before it spreads to still more states.
The Great Lakes Radio Consortium’s Bill Cohen reports:


At stake across the Great Lakes region: millions of dollars of wood that’s used for furniture,
cabinets, flooring, and baseball bats. That’s why Ohio agriculture officials have quarantined an
area around Toledo, banning residents from transporting ash wood out of the area. They’ve also
sprayed pesticide on nearby un-infected trees and taken even more drastic action among the 4,000
trees the beetles had already struck.


David Shlike works for the Ohio Agriculture Department.


“At ground zero, out a quarter of a mile, we cut everything, took it down. And had to chip it. We
hauled these chips to Michigan, and they were incinerated. It’s just a devastating pest and that
pest is going to be hatching out here anytime now between the 1st of May and the 15th of May,
and we were trying to take away its food source.”


It will be a few more months before it’s clear whether or not Ohio’s action has stopped the bugs’
advance.

Maple Syrup Flows With Tradition

April is the month for the highest maple syrup production in North America – and a time when many towns and villages in the Great Lakes states hold pancake breakfasts. The practice of tapping trees for syrup or sugar goes back centuries, long before European settlement.

April is the month for the highest maple syrup production in North America – and a time when
many towns and villages in the Great Lakes States hold pancake breakfasts. The practice of
tapping trees for syrup or sugar goes back centuries, long before European settlement. But as the
Great Lakes Radio Consortium’s Mark Urycki reports, the methods used to make syrup have
changed only a little with time and technology:


In a world where sugar is infused in almost every processed food we eat, it’s hard to imagine a
world without it. But before Europeans introduced honey bees to North America, most native
Americans could only turn to the trees. In a grove of sugar maples, called a sugar bush, Park
naturalist, Dan Best, illustrates the painstaking way Indians boiled down the sap without metal
utensils. It starts with pouring the gathered sap into a hollow log.


“I’m taking this fire-heated rock that’s absorbed a lot of heat from the fire and placing the sap
in the hollow log here. All day and all night for days at a time to get any quantity of sugar made.


Later, white settlers brought cast iron cauldrons. And a bigger improvement in maple sugar
production came with the invention of tin sheet metal. That allowed farmers to pound metal
tubes, or spiles, into the trees and then hang lightweight buckets.


“Tin buckets, like I say, have been used for since the 1860’s. Some places, smaller sugaring
operations, today still find it feasible to use buckets. It’s mounted on a hole under the rim of the
bucket right on the metal spile, so you can keep it, you pivot it right on the spile and empty it into
a gathering pail and today most people use 5-gallon plastic buckets for gathering pails.”


Doesn’t this harm the tree to some degree to be losing sap?


“Not really, if you tap according to the guidelines roughly speaking for every foot of diameter
that you have you can have a bucket. You have to have a good 12 to 18 inch tree to be able to put
on a single bucket. You get up 24 inches so you can put two buckets on and so on but these days
you don’t put any more than three buckets on the trees – too many stresses these days on maple
trees. Between air pollution and the drought we’re having, and so fourth, that we really look
closer. Today’s producers look very close at the health of individual trees.”


(sound of horse team)


Traditionally, the buckets were emptied into a large holding tank. Draft horses like these pulled
the tank on a sled through the forest to a sugar house. Viola Skinner remembers her parents using
a team.


“The tank that we had in our sugar bush had a rail on it and it was drawn by horses on a sled and
with the rail on it we could all jump up and hang on to the rail and go for a ride and we thought it
was fun and games. We didn’t realize we were working dumping into the gathering tank, so
that’s how we did it.”


Amish farmers are still using that method. Fourteen states from New England along the Great
Lakes to Minnesota and Canada produce maple syrup. A common method today is to run plastic
tubing from one tree to another. Sap usually runs by gravity down to a holding tank, saving work
and lessening erosion caused by driving on steep slopes. The tanks of sap are then boiled down
in a sugar house – 40 gallons of sap to get one gallon of syrup. Hans Geiss looks over one
evaporator, which, like most, are fired by wood.


“Probably about 85 to 90-percent are still wood fired.”


So what degree of sweetness do you want here?


“If you take it up from an average of 2 % sugar to about 67 % sugar.


What happens if you’re a little too sweet or a little under sweet?


“If you’re very much below 66% sugar the syrup won’t keep, it will ferment. If it’s much over
67% it will crystallize in the can; it’s like rock candy on the bottom. So you got to be pretty
much right on.”


Maple candy has been the specialty of Debbie Richards’ family. Her grandparents built a sugar
house in 1910 and it’s been the family’s only business ever since.


Richards buys syrup from area Amish farmers to make candy. The sap runs when daytime
temperatures rise above freezing and nighttime temperatures drop below.


Did you have a later season this year?


Yes, quite a bit later. The last three years the season has started earlier than usual. The season
most commonly starts between Valentine’s Day and President’s day. Wasn’t until March that
most people tapped.


Simply because the weather was so cold?


“Right.”


Are there fewer people doing this as maple forests get cut?


“I wouldn’t say there’s fewer people doing it, but the size of the operations are smaller. With
developments going in and roads being widened a lot of the sizes of the farms are being cut
down.”


Although the season started late, Richards says this was a good year, with the sap having a high
sugar content. Sweet news for the maple syrup industry.

Winter: An Old Friend Returned

As the heart of winter approaches, it’s tempting to withdraw from the outdoor world and wait till spring. But Great Lakes Radio Consortium commentator Tom Springer thinks the forgotten benefits of winter far outweigh the hardships:

Transcript

As the heart of winter approaches, it’s tempting to withdraw from the outdoor world and wait till
spring. But as Great Lakes Radio Consortium commentator Tom Springer thinks, the forgotten
benefits of winter far outweigh the hardships.


Outside my window there’s an old sugar maple, grey and bare against the late autumn sky. I’ve
raked up most of its leaves and spread them as mulch on my vegetable garden. It seems like the
tree and me have nothing better to do than wait for spring.


But for a tree, the real work of winter has just begun. To prepare for frigid weather, trees undergo
a process known as hardening off. Their sap withdraws from the twigs and branches and returns
to the roots. And the tree’s roots will continue to grow until the ground freezes solid.


When it comes to surviving winter, I think trees have the right idea. It’s in their nature to slow
down and focus on interior growth. Unfortunately, most of us don’t do that. Instead of adapting to
winter, we try to escape it. We dash from our heated house into a semi-heated garage. We drive in
heated cars – which often have heated seats and even heated steering wheels – and we work in a
heated … Well, you get the idea.


But what would happen if we tried harder to accept winter on its own terms? Might we be happier
and healthier?


Researchers say that people can get surprisingly acclimatized to winter weather. As our bodies
get accustomed to cold, we shiver less and our skin retains more heat. In Australia, scientists have
studied aborigines who sleep outside naked in cold weather. They don’t get hypothermia. In
Japan, shellfish divers have been known to spend hours in the ice-cold ocean, wearing nothing
more than a cotton swimsuit.


Spending more time outside in winter can even make you happier. That’s good news for the 10
million Americans who suffer from Seasonal Affective Disorder. SAD is a form of depression
that’s triggered by the short winter days. Some people take anti-depressants to fight SAD. Yet
researchers find that many people can overcome it without using pills. They just need to get
outdoors and absorb some authentic daylight.


Do you suppose Mother Nature is trying to tell us something? For 50,000 years of human
history, winter was a time of rest and rejuvenation woven between the cycle of seasons. And I
doubt that 75 years of electric indoor heat has changed that. For instance, our bodies still crave
good food in winter – not just fudge and party mix, but homemade soup or a juicy pot roast. And
there’s still something about the solemn purity of winter that calls us to focus inward. To boost
the spirits, there’s nothing like a quiet walk on a snowy Sunday afternoon. It’s also the best time
to read the uplifting books that have languished on the nightstand since summer.


This is, without question, the most trying of seasons. It gets depressingly dark by 6 o’clock, and
the wind howls at the door like a hungry wolf. But the frozen solitude of winter is not a thing to
be feared. Winter is simply an old friend returned, who waits in unspoken silence to wish us well.

States Go It Alone Against Greenhouse Gasses

Some Midwest states are highlighted in a new report
that looks at what states are doing to reduce greenhouse gas
emissions. The Great Lakes Radio Consortium’s Chuck Quirmbach
reports:


The federal government wants no part of international
treaties aimed at reducing pollution linked to global
warming. But a report by the Pew Center On Global Climate
Change says about one-third of the states have taken significant
steps on their own. The study mentions Minnesota’s effort to
plant trees that may help reduce energy consumption and absorb
carbon. Wisconsin is praised for requiring large polluters to
report their carbon dioxide emissions.


University of Michigan professor Barry Rabe offered the study. He
says the budget deficits faced by many states may stifle additional work.


“And there may be an unfortunate irony here that at the
moment when political interest in doing something to
reduce greenhouse gases is greatest, the fiscal capacity to
fund some of these programs and implement them may be at a very,
very low point.”


The Pew Center says the state efforts are no substitute for a
comprehensive national plan. For the Great Lakes Radio Consortium,
this is Chuck Quirmbach reporting.

Invasive Insect Laying Waste to Area Trees

Scientists are working to control a new non-native beetle that’s destroying hundreds of
thousands of ash trees in the Great Lakes region. The Great Lakes Radio Consortium’s
Erin Toner reports:


The Emerald Ash Borer is native to Asia, and probably made its way to the United States
through wood packing materials. Therese Poland is an entomologist with the
USDA. She says so far, the beetles have destroyed 100 thousand ash trees in southeastern
Michigan and southern Ontario.


“We think it’s been here for at least five years and even with some of the other exotic
beetles that have been discovered in recent years, when they were first discovered they
weren’t as widespread as this.”


Poland says there’s a quarantine over the infested areas to keep the beetles from moving
to new areas. Officials are inspecting nurseries to make sure they’re not selling infested
trees. They’re also checking whether tree care companies are disposing of trees properly.
But officials admit they probably won’t be able to stop people who unknowingly transport
infested firewood or yard waste.

When Hollywood producers come looking for the perfect leafy suburb, they often wind up in Evanston, Illinois. This summer’s Tom Hanks flick “The Road to Perdition” was shot here. Filming almost hit a glitch…when Dreamworks suggested removing an old tree to make way for a driveway, the city balked. The scene was filmed; the tree stayed.


Evanston has dozens of trees at least a century old; and some even older than that.


Today, Evanston residents are even fighting a directive from the state’s Department of Transportation to replace obsolete traffic lights because it might mean uprooting some trees. So Evanston’s city Arborist Paul D’Agostino clearly has a rough job: he’s in charge of cutting down trees in a city of tree huggers.


“I’ve had to console people who were crying and hugging their tree and convince them that we were doing the right thing, that there was no choice in the matter.”


Like a handful of tree studded suburbs around Chicago and dozens of cities around the Great Lakes region, Evanston is experiencing a sad summer as Dutch elm disease claims dozens of trees more than half a century old and up to 70 feet tall.


Already more than one hundred Evanston elms have been found to have the killer fungus, and D’Agostino expects the toll to exceed two hundred. Once infected, a tree quickly begins to die…as the fungus blocks the vascular system that delivers water and nutrients to branches and leaves.


D’Agostino explains, standing near two dying elms in front of the Evanston Police Department…


“Both of these trees are in my estimation probably about 40 years old. These are pretty far along now in showing signs of disease…but the typical symptoms of yellowing and flagging leaves has now progressed to dead leaves and bare branches. We’ve got dying sucker growth along the main trunk which means the disease has spread into the main trunk and into the roots, so there’s no curing this tree at this point. The only way to solve this problem now is to remove the tree so it doesn’t spread to other nearby elms.”

So five days a week, three crews of three men each are out on Evanston streets, taking down very old, very tall trees.

For this relatively affluent, leafy suburb defined by its generous trees, the return of Dutch elm disease brings back bad memories of summers nearly 30 years ago, when hundreds of trees were cut down, destroying the canopies of tree tops that shade many of Evanston’s streets.


Still, there are 27,000 trees on city property in Evanston, and D’Agostino estimates three times that many on private property.


Today the suburb’s green and shade is created by a careful mix of hybrids and hardier trees, including Kentucky coffee, linden, gingko, honey locust and horse chestnut.


And the city is moving ahead with plans to continue replanting with diverse species to avoid future epidemics.


But ever a hotbed of activism, Evanston environmentalists of every stripe are on the case, badgering officials to do more than just identify and remove diseased trees.


Many want the city to inoculate the elms against the fungus.


“I’m a conservative republican, not at all a tree hugger. Al Gore and I would not mix ”


Virginia Mann has successfully organized the 13 other homeowners on her block to foot the bill to inject the elms on their street.


There are nine healthy elms on the block, and Mann and her neighbors have decided to adopt and inject three trees each year, at a cost of about $600 per tree.


“I know they add value to my community, I know they add value to my property, and I
know they keep my cooling costs down and I know there’s nothing I can do to replace them. So if you don’t take care of them, that’s it, they’re gone.”


While prognosis for the inoculated trees is excellent, there are no guarantees.
Dutch elm disease is spread both by beetles who carry the fungus on their hairs, and through root grafts between neighboring trees.


There is no way to protect the trees from root grafts. No one is sure why the disease is back and moving so aggressively.


Some citizens say, though inoculations can’t guarantee saving a tree, with only about 3,000 elms left in Evanston they’d rather try, than accept what the city officials seem to believe is the inevitable demise of the species in their suburb.
“Well, you can see my tree suffered an amputation this year.”


Mimi Peterson’s front porch on Ashland Avenue is shaded by a tall sturdy-looking survivor.


“It’s one of the few elms left on the block. You can also see across the street where we lost a really huge one. We’ve already lost nine trees on the block.”


She is well known in town for raising her voice as an advocate for trees; five years ago she hounded the city into more routine tree trimmings.


Now Peterson’s spearheading a group called TREE…To Rescue Evanston Elms, looking to suburbs like nearby Hinsdale…a place with more elm trees and a more aggressive Dutch elm disease prevention program.


Peterson says she agrees that diseased trees should go…but more needs to be done to protect still healthy elms.


Mostly Peterson’s group wants the city to spend more time and money looking for trees to save rather than trees to cut.
