One of America’s favorite shade trees is being killed by the millions. A
tiny invasive insect is to blame. The emerald ash borer has dealt an
unexpected blow to cities, homeowners and industries that work with ash
trees. The GLRC’s Rebecca Williams reports… the ash borer has been
especially devastating to the nursery industry:


Everybody thought ash trees were perfect. That’s because they’re great
shade trees, they grow fast, they turn yellow and red and purple in the
fall. Ash trees were the go-to tree for a lot of cities after Dutch elm
disease killed off most of the nation’s elm trees 30 years ago. Scientists
thought ash trees were pretty much invincible to pests.


Then… the emerald ash borer hitched a ride to the States in cargo from
China… and changed everything.


“We couldn’t believe it. It’s like We were stunned, you know, wait a minute,
this is something we can’t even sell anymore.”


Amy Camido is a certified nurseryman. She sells trees and shrubs at Ray
Wiegand’s Nursery. It’s a large nursery outside of Detroit… close to
where the ash borer was first discovered in 2002. In 2003, Michigan
officials banned the sale of all ash trees. That meant nurseries had to cut
down and chip or burn all of their ash tree stock.


“Gosh, when they told us we couldn’t sell them anymore, it was like, pick
them up and put them in the bio-grinder, they were gone. These trees,
they weren’t even trees that were infested.”


Camido says Weigand’s Nursery destroyed 6-thousand trees. That cost
them a half million dollars. She says the nursery lost out on three fronts.
They grew ash trees and they sold them to homeowners and landscapers.


Ray Weigand says the nursery… like many around here… lost a third of
its market.


“Once you lose it you lose it. It’s hard to make money up in any
industry. We just plant other products and hope that they bloom out and
people like them.”


Weigand says now… instead of selling lots of the same type of tree…
they’ll have to plant many different species to hedge their bets. Nurseries
also want the federal government to compensate them for their losses,
but that’s looking unlikely. Congress continues to slash funding for
fighting the emerald ash borer… and states are not putting up any extra
money.


Nursery groups say the beetle should be a national priority… because it’s
not just a Midwest issue.


Mark Teffeau is with the American Nursery and Landscape Association.
He says the borer’s hurt sales of ash trees nationwide.


“Right now it’s a buyer’s market. The ash prices have basically plummeted
to the point that I know growers who have realized there’s no market for
these trees and then they’re pulling them up and destroying them. Either
that or trying to sell them at reduced prices in places where ash borer isn’t
present.”


The only state that’s banned all sales of ash trees is Michigan, but the ash
borer has also infested trees in Ohio and Indiana. Those states have not
completely banned sales of ash. Instead, they’re restricting sales from
infested areas. Officials in those states say some nurseries are still able
to sell ash trees… but not a lot of people are buying them.


Nursery groups are putting pressure on state and federal officials to keep
the ash borer contained. The beetle only moves about a half mile a year
on its own, but people help it spread a lot farther… by moving firewood
infested with the beetle. Just one piece of infested firewood can start a
new outbreak.


Patricia Lockwood is the ash borer policy director for Michigan. She
says states are getting the message out that moving firewood spreads the
beetle.


“We’re continually on a daily basis outreaching through schools,through the
libraries, we are doing billboards, public service announcements. We
really are outreaching to a tremendous amount of individuals. We never
do enough but we’re doing the best with the resources that we have.”


But even though there are laws against moving firewood, critics say
those messages are not getting through to everyone. Nurseryman Amy
Camido says people don’t seem to care about the ash borer until it affects
them directly.


“Just as recent as last summer, last fall, people were bringing in branches
and saying, you know this tree isn’t looking as good as it should and I’d
say, ‘you know it’s an ash tree?’ and they’d go, ‘Yeah, so?’ and I say
‘you know about the emerald ash borer problem?’ ‘Nooo…’ ‘Like, how
can you not know? How can you not know??”


Camido says she hopes people in the rest of the country can be spared
losing their ash trees, but she’s not feeling very optimistic these days.


Scientists say a lot’s at stake if the ash borer isn’t stopped. They say if
the beetle spreads throughout the country, more than 8 billion ash trees
will be killed, and they say nurseries, the timber industry and taxpayers
will foot the bill for those losses… running in the hundreds of billions of
dollars.

States Struggle to Control Ash Borer

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams reports cities and states are struggling to find money to keep the beetle from spreading:

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams
reports cities and states are struggling to find money to keep the beetle
from spreading:


Once emerald ash borers chew their way into your ash trees, there’s
pretty much only one thing you can do.


(Sound of chainsaw and tree cracking and falling)


Crews here have been sawing down and chipping up trees six days a
week. In some places, crews are cutting down both dead and live trees.
Dead trees are a safety hazard. Cutting live trees near infested areas can
help contain the beetles.


The emerald ash borer is native to China. Scientists think it got in on
wood packing crates more than ten years ago. The emerald ash borer eats
through the living part of the tree just underneath the bark. The beetles
cut off the tree’s water and food supply… so it starves to death. 15
million ash trees are dead or dying in Michigan. Hundreds of thousands
are dying in Ohio, Indiana and Ontario, and it could spread to other states
soon.


Some cities have been hit really hard. For example, some of the trees in
Ann Arbor, Michigan have been dead for a couple of years. Kay
Sichenader is the city’s forester. She says she’s worried about limbs
breaking off trees, or bark falling off in 80 pound chunks.


“There’s some terrifically bad ones out there. Nothing will make me
happier than when those trees are down, I gotta tell you.”


This isn’t the first time cities have lost big shade trees. Dutch elm
disease almost wiped out American elms in the 1960’s and 70’s. It’s a
little ironic: people planted ash trees to replace the elms because they
thought ash trees were invincible.


That love of ash trees means cities are losing 20 or 30 percent of their
trees, and they’re spending millions of dollars to take trees out.


Forester Kay Sichenader says her city normally takes out a thousand old
trees a year. Now, she’s got ten times as many trees to cut down.


“If I never bumped it up, and we just remained with our thousand a year,
we would never change because it would take me ten years to get the ash
out. In the meantime I’d have 10,000 more dead trees to deal with. It’s
sobering.”


Sichenader says the city’s trying to get the dead ash trees out as fast as
they can. She’s contracted five extra crews to saw down trees. She
hopes they’ll be done by the end of the year, but it might be longer.


Many homeowners are getting impatient. They’re worried about big
branches falling on their cars or homes. Or worse, falling on their kids.


Laura Lee Hayes lives in a cul-de-sac with four infested ash trees. She
points out a big branch on her neighbor’s dead tree.


“This whole piece is just laying here, ready to pull off, and there are
small children that play in this yard. That’s why I look to my city to get
over here and get these trees down. There’s a real frightening aspect to
that.”


Hayes says she tried to pay to take the trees down herself, but she found
out it would’ve cost more than a thousand dollars.


In Indiana, homeowners now have to spend their own money to get rid of
dead trees in their yards. State officials say they can’t afford to keep
cutting down live ash trees to slow the infestation. The state won’t be
giving money to help cities cut down dead trees either. That could mean
the emerald ash borer will spread unchecked.


At first, the federal government sent states several million dollars to fight
the beetle, but now the money’s just trickling in. In 2004, Michigan
Governor Jennifer Granholm asked President Bush to declare the state a
federal disaster area. That request was denied. Recently, officials in
Ohio and Michigan said they’ll have to cut back on containing new
infestations.


These trends worry scientists.


Deb McCullough is a forest entomologist at Michigan State University.
She says states barely have enough money to monitor how far the beetle’s
spreading, and she says a lot more money’s needed for ad campaigns to
tell people to stop moving firewood. The beetle spreads fastest when
campers or hunters move infested wood.


“You have to look down the road, and either you spend millions of
dollars today to try to contain emerald ash borer or we’re going to be
looking at losses in the tens of billions of dollars in the future, and it’s not
too distant of a future.”


McCullough says if more funding doesn’t come in states might need to
have timber sales to take ash out before the beetle kills it. And cities will
still be paying millions of dollars to take out dead trees. That means
people who live in those cities might see cuts in other programs or have
to pay higher taxes.


Deb McCullough says the economic impacts are serious… but the
environmental impacts could be even worse. She says it’s hard to know
how wildlife might be affected if we continue to lose millions of ash
trees.

Trade Increasing Number of Exotic Species

Exotic insects and diseases that attack plants can be very destructive and cost millions of dollars to fight.

Exotic insects and diseases that attack plants can be very destructive and
cost millions of dollars to fight. Just ask those cities fighting the
invasion of the emerald ash borer and the Asian longhorned beetle. The
Great Lakes Radio Consortium’s Rebecca Williams reports… a recent
study looks at where new potential pests are coming from:


Inspectors at airports, ports and borders nab between 40 and 60 thousand
different potential plant pests each year. That’s according to a study in
the journal, Biological Invasions.


Author Deb McCullough says global trade is leading to an increase in the
number of non-native insects and diseases that could become problems.


“China in particular which has become one of our major trading
partners…most of the kinds of climate that you’ll find in China, you’ll
find somewhere here in the U.S., and there’s really an awful lot of
opportunities for exotic insects to become established here.”


McCullough says it’s hard to estimate how many new potential pests
could be slipping past inspectors. She says at best, inspectors go through
just 2% of agricultural cargo coming into the U.S. each year.

Ten Threats: Expanding the Seaway

  • A freighter leaving the Duluth harbor in Minnesota. (Photo courtesy of EPA)

One of the Ten Threats to the Great Lakes identified by many of the experts we surveyed
is dredging channels deeper and wider for larger ocean-going ships. In the 1950s, engineers
carved a shipping channel from the Atlantic Ocean to the Great Lakes via the St. Lawrence
River. The St. Lawrence Seaway was to make ports in cities such as Chicago and Duluth main
players in global commerce. Today, the Seaway operates at less than half its capacity.
That’s because only five percent of the world’s cargo fleet can fit through its locks and
channels. For decades, the shipping industry has wanted to make them bigger. David
Sommerstein reports:

We’re continuing our series Ten Threats to the Great Lakes with a look at the idea of
letting bigger ships into the lakes. Lester Graham is our guide through the series.


One of the Ten Threats to the Great Lakes identified by many of the experts we surveyed
is dredging channels deeper and wider for larger ocean-going ships. In the 1950s, engineers
carved a shipping channel from the Atlantic Ocean to the Great Lakes via the St. Lawrence
River. The St. Lawrence Seaway was to make ports in cities such as Chicago and Duluth main
players in global commerce. Today, the Seaway operates at less than half its capacity.
That’s because only five percent of the world’s cargo fleet can fit through its locks and
channels. For decades, the shipping industry has wanted to make them bigger. David
Sommerstein reports:


(Sound of rumbling noise of front-loaders)


The port of Ogdensburg sits on the St. Lawrence River in northern New York State.
When the Seaway was built, local residents were promised an economic boom. Today
what Ogdensburg mostly gets is road salt.


(Sound of crashing cargo)


Road salt and a white mineral called Wallastonite – the Dutch use it to make ceramic tile.
Front-loaders push around mountains of the stuff. In all, the port of Ogdensburg
welcomes six freighters a year and employs just six people.


Other Great Lakes ports are much bigger, but the story is similar. They handle low-value
bulk goods – grain, ore, coal – plus higher value steel. But few sexy electronic goods
from Japan come through the Seaway, or the gijillion of knick-knacks from China or
South Korea.


James Oberstar is a Congressman from Duluth. He says there’s a reason why. A
dastardly coincidence doomed the Seaway.


“Just as the Seaway was under construction, Malcolm McLean, a shipping genius, hit on
the idea of moving goods in containers.”


Containers that fit right on trains and trucks. The problem was the ships that carry those
containers were already too big for the Seaway’s locks and channels.


“That idea of container shipping gave a huge boost of energy to the East Coast, Gulf
Coast, and West Coast ports, and to the railroads.”


Leaving Great Lakes ports behind ever since the regional shipping industry has wanted to
make the Seaway bigger.


The latest effort came in 2002, when the U.S. Army Corps of Engineers studied the
economic benefits of expansion. The study said squeezing container ships through the
Seaway would bring a billion and a half dollars a year to ports like Chicago, Toledo, and
Duluth. But if you build it, would they come?


“Highly doubtful that container ships would come in. Highly doubtful.”


John Taylor is a transportation expert at Grand Valley State University in Michigan.
He’s studied Seaway traffic patterns extensively. He says there would have to be “a sea
change” in global commerce.


“Rail is too competitive, too strong moving containers from the coast in and out say from
Montreal and Halifax and into Chicago and Detroit and so on, too cost-effective for it to
make sense for a ship to bring those same containers all the way to Chicago.”


The expansion study sparked a flurry of opposition across the Great Lakes. It failed to
mention the cost of replumbing the Seaway — an estimated 10 to 15 billion dollars. It
didn’t factor in invasive species that show up in foreign ships’ ballasts. Invasives already
cost the economy 5 billion dollars a year, and environmentalists said it glossed over the
ecological devastation of dredging and blasting a deeper channel.


Even the shipping industry has begun to distance itself from expansion. Steve Fisher
directs the American Great Lakes Ports Association.


“There was quite a bit of opposition expressed through the region, and in light of that
opposition we took stock of just how much and how strongly we felt on the issue and
quite frankly there just wasn’t a strong enough interest.”


Most experts now believe expansion won’t happen for at least another generation.
Environmentalists and other critics hope it won’t happen at all.


So instead, the Seaway is changing its tactics. Richard Corfe runs Canada’s side of the
waterway. He says the vast majority of Seaway traffic is actually between Great Lakes
ports, not overseas. So, the Seaway’s focus now is to lure more North American shippers
to use the locks and channels.


“Our efforts have to be towards maximizing the use of what we have now for the benefit
of both countries, the economic, environmental, and social benefit.”


Today, trucks and trains haul most goods from coastal ports to Great Lakes cities.
Shippers want to steal some of that cargo, take it off the roads and rails, and put it on
seaway ships headed for Great Lakes ports.

A new invasive disease that affects soybeans may be on its way to states in the Great Lakes region. Experts say it’s a serious disease – but their biggest challenge right now is caling farmers who fear the worst. The Great Lakes Radio Consortium’s Tracy Samilton reports:


Soybean rust is a fungus that attacks soybeans. It first appeared in China in the 1920’s. Soybean rust travels easliy and quickly on wind currents. It made its first U.S. appearance in 2004 in the southeast, probably arriving on the back of Hurricane Ivan. Experts say it could make its way to northern states this spring. John Whiteman is Director of the Indiana Soybean Board Research Program. He says he’s fielding a lot of calls from very worried farmers.


“They’ve heard the worst horror stories and they’ve not heard the other side yet. So all they’ve heard is the 80% yield loss, not that it can be controlled and here’s how you can conrol it.”


Whiteman says different types of fungicides can either prevent or kill soybean rust. He says farmers are being told to prepare ahead of time, so they won’t have to face devastating crop losses.

Despite warnings that global warming is causing the Arctic to warm up at twice the
rate of the rest of the world, the Bush administration is not changing its policies
on emissions in the U.S. The Great Lakes Radio Consortium’s Lester Graham reports:


Earlier this month 300 scientists presented a four-year study that concluded the
Arctic was warming up right now. The report indicated the northern ice cap was already
diminished by 15 to 20 percent, and by the end of this century half of the Arctic’s summer
ice cover would be melted and polar bears could be nearly extinct. The study predicted that
the wildlife in the Arctic and the people who depended on it for food would be in dire straits.


But even with the new evidence that the Arctic is facing worse warming than first predicted,
the Bush adminsitration is not changing its course. The White House has indicated the U.S.
would lose too many jobs and have to restrict its economy more than other nations such as
China and India if it were to adhere to the Kyoto global warming treaty. So far, the Bush
administration has agreed only to fund further research on the issue.

China is banning the import of scrap electronics. That eliminates one place where some U-S companies were selling broken computers and electronic junk under the guise of “recycling.” The Great Lakes Radio Consortium’s Lester Graham reports:


Each year, more than 60-million desktop computers are taken out of service in the U.S. About 85-percent of them end up in landfills. But some people take their old computers, electronics and appliances to be recycled. Unfortunately, that sometimes simply means being shipped to China and other Asian countries where the electronic gear is burned to retrieve the metal such as copper and steel. Burning the electronic gear releases all kinds of toxic chemicals. Now, China’s main English language newspaper, CHINAdaily, reports the government there is banning the imports of scrap electronic goods. The newspaper reports this marks a change in the Chinese government’s policy of always putting economic conerns in front of less tangible needs such as the environment.

Asian Food Stores Adding to Carp Problem?

Over time, invasive species have upset the natural balance of the Great Lakes. Now, officials are
working frantically to stop a new threat, the Asian carp. The carp lives in tributaries connected to
the Great Lakes. But there may be another route into the water system – through Asian food
stores. As the Great Lakes Radio Consortium’s Karen Kelly reports, live carp can be purchased
in many cities throughout the region:


“This one in Chinese, layoo. This one in Chinese…”


York Alooah stands in front of a crowded fish tank at the 168 Market in Ottawa, Canada’s capital.
He points to the fat, foot and a half-long bighead carp swimming behind the glass.


The fish are brought to his store by truck from Toronto. They originate at farms in the southern
U.S.


Speaking through an interpreter, Alooah says it’s unlikely that a carp could escape during
delivery.


“They use a big truck and have the fish tank inside.”


Alooah says the fish can’t jump out because the tanks are covered. Still, the live sale of these fish
has many people worried. That’s why states like Indiana, Michigan, Minnesota and Ohio have
banned the possession of live Asian carp.


Several states are also asking the federal government to add these carp to a list of invasive species
considered harmful. That listing would make it illegal to possess them alive.


In Canada, there aren’t laws like that on the looks. But officials say they’re considering action.


Nick Mandrack is a research scientist with the Canadian Department of Fisheries and Oceans. He
says Canadian researchers are keeping an eye on an Asian carp population that’s moving north up
the Mississippi River. They worry that the fish will migrate through a manmade canal into the
Great Lakes.


“If they were to become established, either through dispersal up from the Mississippi or
unauthorized release as a result of the live food trade, they could have enormous impacts on the
Great Lakes ecosystem, which would likely result in a dramatic decline in the biomass of game
fishes.”


That’s because two species of Asian carp eat the same food as small forage fishes. And those
forage fishes are what the larger gamefish rely on. The Asian carp are too big for the gamefish to
eat.


Researchers are also worried about two other species. The black carp could wipe out endangered
mussels that live in the lakes. And the grass carp destroys aquatic plants where native fishes live.


Mandrack has seen both the bighead and the grass carp sold live in Asian food stores. He and
others say that poses one of the greatest threats to the Great Lakes fish population.


(sound of fish scaling)


Back at the 168 market in Ottawa, York Alooah uses a long knife to butcher and scale a fish he’s
pulled out of a tank. He laughs when an interpreter asks if people ever leave his store with live
carp.


“When people buy, it’s not alive. He clean and kill and clean everything.” Is it never alive?”
“Never.”


In fact, the city of Chicago is hoping to guarantee that doesn’t happen. Officials want stores that
sell live carp to operate under permits. And the fish would have to be killed before it left the
store.


But not all fish is bought for consumption. There’s also concern about a Buddhist practice in
which captive animals are released into the wild.


Tookdun Chudrin is a nun with the MidAmerica Buddhist Association. She says the carp sold in
food stores are not likely candidates for release.


“I think that people would not buy such a large fish for liberation because they tend to get very
small animals and very often will put them in a pond at a temple.


And Chudrin says, Buddhists would want to know if the religious practice was harming other
animals.


“I think definitely if there were a sign saying that said putting these fish in the lakes could be
detrimental to other species, I think people for sure would heed that if this was going to endanger
others and the people knew it, I don’t think they’d do that.”


So far, only two Asian carp have been found – in the Canadian waters of the Great Lakes.
Another was released in a fountain in Toronto, just a few blocks from Lake Ontario.


Whether from pranks, or acts of kindness, some fear it’s only a matter of time before more carp
get into the water. They say the Great Lakes could become a giant carp pond, and many of the
species we’ve come to know would disappear.

Forests in the Midwest may be under siege from exotic species more often in the future… partly because of international trade. The Great Lakes Radio Consortium’s Rebecca Williams reports:

The Asian longhorned beetle is native to China.
The beetle caught a ride to the U.S. in the wooden packing material of
imported goods. So far, the beetle has been found in New York and
Chicago. 


Once a tree is infested with beetles, the best way to stop the beetles from spreading is to destroy the tree.

A National Academy of Sciences study predicts that threats to native species will increase as trade opens up between the U.S. and China. The authors say that China may become a new “donor region” for species that could become invasive.

Entomologist Deborah McCullough is an author of the study.

“You can kind of visualize this whole complex of insects and weeds and plant pathogens in Asia that haven’t had a pathway, they haven’t had a route to be brought to the country yet… and we really don’t know what all could end up coming in.”

Dr. McCullough says because China’s range of climates and plant life are similar to that of the U.S., many species that make it over here have a chance to become established.
