There might be a new weapon to use against a
destructive pest. Rebecca Williams reports the emerald
ash borer has killed more than 30 million ash trees in
eight states and Ontario:

No one’s been able to stop the tiny green beetle from killing trees. But
officials are hoping a new insecticide will help.

Researchers at Michigan State University ran trials for one year with a
chemical called Tree-age. In those tests, the insecticide killed all of the
beetles. The state of Michigan has approved the insecticide for use on ash
trees. Indiana, Ohio and West Virginia are also considering it.

Jim Bowes is with the Michigan Department of Agriculture. He says the
emerald ash borer probably can’t be stopped, but the insecticide might
slow the beetle’s spread.

“Nobody here and I don’t think anybody in the federal government at this
point is talking about eradication. I think everybody is talking about how
are we going to coexist?”

Bowes says the insecticide might be able to save trees in your yard, if
the infestation is caught early enough.

Lessons From Insect Infested Wood

Ash trees are dying by the millions because of an infestation of a
foreign bug. In one town, they’re using the dead wood to help build a
library. Lester Graham reports the wood beams and flooring will be a
permanent exhibit to remind visitors of the trees that were once there
and the cost of imported pests:

Ash trees are dying by the millions because of an infestation of a
foreign bug. In one town, they’re using the dead wood to help build a
library. Lester Graham reports the wood beams and flooring will be a
permanent exhibit to remind visitors of the trees that were once there
and the cost of imported pests:


Craig Novotney is driving a team of black draft horses, some young
Percherons, through a wood lot. They’re dragging a pretty good sized
log out into the open to be trucked away and turned into lumber. They
could have used a bulldozer to do this job, but that would have damaged
a lot of the other trees in these woods:


“It’s a lot less impact on the forest floor. You don’t ruin near as
much stuff, you know, getting it out with horses. It’s a kind of
lighter approach to it.”


Sixty ash trees have been cut down on this four-acre piece of land.
They were all dead, killed by a bug called the emerald ash borer. The
wood from these dead trees will be used to make flooring, wood trim,
and to be support beams for a new branch library.


The architects knew they wanted to use ash, as a way of reminding
people of this disappearing natural resource. But it was the flooring
contractor who suggested the ash wood they needed was on the very
property where the library is to be built.


John Yarema owns Johnson Hardwood Floors:


“We were originally came out to look at flooring and ash. And when we
told them we could use the material off the site, they were excited.”


Rather than just flooring, Yarema suggested the architects use the dead
ash trees for some of the structure of the building, so that people
could see the damage the emerald ash borer had done, a sort of
permanent exhibit.


“One wall – it’s a 90 foot wall facing the woods – all glass. So, in
front of that, we’re going to have trees, emerald ash borer-killed
trees supporting that wall.”


The trees will still bear the marks of the damage done by the bug.
The ash tree is a popular tree, but like this place where they’re
chopping down the trees, city after city has had to cut down all of
their ash trees in an effort to stop the spread of the emerald ash
borer.


Despite efforts to quarantine infested areas, the emerald ash borer
is spreading. It was first detected in Michigan in 2002. It probably
came in shipping crates from China. The pest already has spread to a
half dozen other states and Ontario. The bug is being spread in part by people
hauling firewood with them on vacation and hunting trips, and in some
cases by nursery stock being shipped out of the area.


Josie Parker is the Director of the Library District in Ann Arbor,
Michigan where this new branch library is being built.


“Because it’s a public building, it will tell the story of what can
happen and did when there’s an infestation. This building will always
be here. The emerald ash borer tracings will be evident in the wood.
So, we’ll be able to explain (to) science classes and anyone who’s
interested what happened to ash trees and why we need to be more
careful about insect infestations.”


A lot of the dead ash has been cut up for firewood. But some people
have felt that the wood shouldn’t be wasted. It should be preserved
somehow. John Yarema says it makes him sad, seeing the ash tree
disappear. But, he likes the idea of using these ash trees in a way
that might serve as a lesson:


“It’s nice in the sense that it’s in an educational facility and not
chopped up into firewood. So, in that way, you feel better than
burning it in a fireplace. If we can make a statement and maybe
somebody will look at it, maybe a child will look at it and say, you
know, ‘Wow, this is…’ because (in) 40 years there aren’t going to be
any. The only ash trees that’ll be around will be in the flooring, the
walls, the ceiling and in the structure. I think we just all need to
open our eyes and hope for the best, I guess.”

Firewood Fuels Ash Borer Problem

If you’re packing up the car for a camping trip, you can’t
leave without the marshmallows and duct tape and bug spray, but
in more and more places, you can’t take firewood with you. That’s because government officials are worried about a destructive beetle
that people are spreading by moving firewood. The GLRC’s

If you’re packing up the car for a camping trip, you can’t leave without the
marshmallows and duct tape and bug spray, but in more and more places, you
can’t take firewood with you. That’s because government officials are
worried about a destructive beetle that people are spreading by moving
firewood. The GLRC’s Rebecca Williams reports:


(Sound of RV humming)


Butch Sloan can’t imagine camping without a fire:


“Sitting back and watching the wood burn and kinda dreaming about old times
or whatever, you know? That’s part of your camping. Yeah, you gotta have
your camp fire!”


Sloan’s been coming to this Michigan campground from his home in Ohio for 20
years now. For the past few years, it’s been illegal for anyone to move
hardwood firewood over the state line. There can be steep fines if you’re
caught.


That’s because of the emerald ash borer. It’s an invader from Asia that’s
killing millions of ash trees in the upper Midwest. Moving just one piece
of infested firewood can start a new outbreak. Beetles can emerge from the
wood and fly to healthy ash trees.


Butch Sloan says he brings wood from construction sites or buys firewood at
the campground instead:


“As far as trying to bring regular firewood across the state lines, the fines
are just too high. I don’t want to take a chance on it, you know? We bring
the two by fours and stuff like that, and that’s good fire, good cooking, you
know!”


But there are plenty of campers who ignore the laws and bring firewood with
them. That’s why states such as Michigan and Ohio are setting up
checkpoints along highways. They’re trying to catch people sneaking
firewood out of infested areas.


(Sound of traffic)


Here on a two lane country road in Northwest Ohio, every car and truck is
being stopped. State workers ask the drivers if they’ve got firewood.


“If we do find someone that has brought firewood with them, we ask them to
pull into a parking lot and at that point we begin to interview them to find
out where the firewood came from.”


Stephanie Jaqua is a crew leader with the Ohio Department of Agriculture.
She says a lot of the people they catch don’t understand the quarantine
laws. But she says others don’t think they’re part of the problem:


“We have had people in the past say there’s no ash in the back of my truck, you know,
there’s no way I’m transporting emerald ash borer, and then you get to the
bottom and there are four pieces of ash in the bottom.”


Jaqua says that’s why the laws are written the way they are. It’s illegal
to move any hardwood firewood out of quarantined areas, not just ash wood.
Jaqua says the best thing campers can do is buy firewood where they camp and
burn it all up at the site.


A lot of campers say the firewood rules are annoying, but the rules have
changed everything for some people.


Jim Albring owns Lumber Jacks Quality Firewood. His business is in
Michigan, just a mile and a half from Ohio. He says before the ash borer
arrived, most of his customers were in Ohio. Then, suddenly, he couldn’t
move firewood across the state line.


“It was profitable and we were increasing by 25-30% a year until the ash
borer hit. And now we’ve dropped uh, boy, I don’t even know. I don’t really
look at the figures too much any more because it’s disheartening.”


Albring says at first, he could only sell to people a few miles away in
Michigan, so his customer base totally dropped out. He says these days,
people from Ohio still drive up and try to buy firewood from him.


“If we know or we’re suspicious it’s going back to Ohio, we tell them how
heavy the fines are and then they usually back off right away and they don’t
try to get it.”


That’s the problem with trying to stop the destructive insect from spreading
across the country. Even government officials admit there’s no way to stop
every single person from moving firewood.


Patricia Lockwood directs ash borer policy for Michigan:


“I think it’s going to be extremely difficult and we’ve known that from day
one, to stop it. What we have always agreed on is we’re buying ourselves
time. What we’re looking for is time so that the science can catch up.”


And researchers are scrambling to find something that will stop the ash
borer, a natural predator or a perfect pesticide. But scientists say
states have to contain the infestations in the meantime.


That means there’s a lot of pressure on campers and hunters to change their
habits. Tossing some wood in the back of the truck on the way up north used
to be pretty harmless. Now it’s changing entire landscapes, as millions of
trees get wiped out by the beetle.

Termite Worries More Myth Than Fact

An email is spreading across the Internet warning about termites in
mulch stockpiles from the hurricane ravaged Gulf Coast. As the GLRC’s
Tana Weingartner reports, the email is more rumor than fact:


The email says Formosa termite infested trees downed by Hurricane
Katrina are being mulched and sold off by the state of Louisiana. The
writer warns the infected mulch could end up at your local big box
hardware store.


The Mulch and Soil Council’s Executive Director says that’s just “not
true.” Robert LaGasse says the well-monitored clean up operation and a
preexisting quarantine banning wood products from being shipped out of
the area are part of what keeps the termites from spreading.


“We’ve never had an infestation issue with termites in mulch, in bagged
product.”


LaGasse adds even if the mulch was shipped out of the region, the
chipping and grinding process along with the heat generated by the
mulch would be enough to kill any termite.


The Formosa termite has been a problem for parts of the South since it
was first brought into the country after World War II.

Bed Bugs Biting Again

Health officials across the country say some nasty night critters are
making a comeback. Bed bug cases are up, and in 2005, they were reported
in 43 states. The GLRC’s Tana Weingartner reports:


It turns out your mother knew what she talking about, when she
reminded you to “sleep tight” and “don’t let the bed bugs bite.” The
blood-sucking insects are popping up in hotels and homes around the
country.


Steve Chordas is a public health entomologist with the Ohio Department
of Health. He blames increases in travel and the banning of some
pesticides for the bed bug resurgence, but, he says, the bugs are more of
a nuisance than a public health threat.


“There’ve been some diseases that have been isolated from the bed bugs,
but it’s not been shown, scientifically at least, that these are able to be
vectored by the bed bugs or transmitted from the bed bugs to a new
victim.”


Bed bugs are like tiny hitchhikers that can hide in your luggage and
clothing if you stay in an infested hotel room. Extensive cleaning and
insecticides are usually needed to get rid of a bed bug infestation.

States Struggle to Control Ash Borer

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.

Another State Scales Back Ash Borer Fight

Faced with a severe cut in federal funding, the state of Ohio is scaling
back its fight against the emerald ash borer. The burrowing insect has
killed millions of ash trees in Michigan, Indiana and Ohio, and
researchers fear the bug will soon spread to other states. The GLRC’s
Mike Thompson reports:


Since the emerald ash borer was first spotted in Ohio in 2003, the state
has cut a quarter of a million ash trees – most of them in the northwest
part of the state. The federal government has paid for the cutting, but
Ohio’s federal funding for ash tree protection has shrunk from 17 million
dollars to about 1 million dollars.


So state officials say they will reduce the cutting of ash trees to keep the
bug from spreading. The state will let the northwest Ohio infestation run
its natural course, choosing instead to cut trees in other parts of the state.


Melissa Brewer speaks for The Ohio Department of Agriculture


“If you ignore those infestations, those infestations are going to grow and
you are going to see an expedited demise of our ash trees.”


Ohio agriculture officials say they will also use federal money to monitor
the insect, enforce quarantines and educate the public.

Combating Inland Invasives

Invasive plants, fish and other creatures are threatening many inland
lakes. Evironmentalists and property owners are trying to stop the
spread…before the invaders dramatically alter the smaller bodies of
water. The Great Lakes Radio Consortium’s Ann-Elise Henzl reports:


It’s strange to think that plants and animals from Europe, Asia and Africa
are living in small lakes in the Midwest. Boaters have taken invaders
there…after picking them up in the Great Lakes.


The big lakes are home to more than 160 aquatic invasive species,
including Eurasian Watermilfoil. The stringy plant grows in thick
clusters that get up to 12 feet tall.


“I have seen lakes where if you fell out of the boat in these massive
weeds and you weren’t wearing a life jacket, I don’t care how good a
swimmer you are, you would sink. You can not struggle your way
through these thick entanglements of weeds.”


Ted Ritter leads an effort to reduce aquatic invasive species…in
Wisconsin’s Vilas County.


(Sound of pontoon motor)


On one afternoon he takes his pontoon boat on a lake that had an
infestation of Eurasian Watermilfoil.


“It is a very aggressive plant and it has no natural predators to control its
growth, it grows up to two inches a day.”


When Eurasian Watermilfoil finds conditions it likes, it takes over
quickly. A piece as small as two inches can break off, and float away to
create a new plant.


Eurasian Watermilfoil is widespread in northern Michigan… northern
Wisconsin and other places. It’s one of dozens of aquatic invasive
species on the move in the region.


One of the worst invaders is zebra mussels. They can ravage a lake’s
ecosystem.


(Sound of motor boat)


So far, they’ve made it to just one lake in northern Wisconsin. Mike
Preul with the Lake Superior Chippewa scuba dives there, to count the
mussels. Three years ago, he found 7 adults per square meter. This year,
he counted more than 14-hundred:


“They’re still increasing. What they’ve seen in other systems is that just
like with any other exotic species they’ll come in, the population will
explode, they’ll kind of eat themselves out of house and home, and then
they’ll come down to a level and reach a steady state.”


No method has been discovered to get rid of zebra mussels, but there are
ways to control some invaders.


Herbicides can be used to kill Eurasian Watermilfoil, and some property
owners chip in to buy aquatic insects to kill the plants.


Les Schramm did that on his local lake:


“As the larvae hatches it burrows into the stem of the Eurasian
Watermilfoil and sort of eats out the center vascular part, and it falls over
and dies.”


People fighting aquatic invasive species say it’s like fighting weeds in a
garden — the work never stops and it can be expensive.


Ted Ritter of Vilas County says it costs thousands of dollars to treat a
lake once. So, often people do nothing.


Ritter says that can hurt the environment. He says it can also threaten the
economy, in areas like northern Wisconsin that rely on tourism.


Ritter says the invaders can reduce the appeal of a lake. He mentions a
plant called “curly leaf pondweed.” When it dies in the middle of
summer, it creates algae blooms that look like slimy green pillows:


“When people arrive at resorts and they look out and they see that very
unappealing lake they say ‘I’m not staying here,’ and they go somewhere
else. When realtors bring prospective buyers out to look at a property,
people get out of their car and they go right to the lake and they say ‘oh
my, I’m not even interested in looking at the house. This lake is
horrible.'”


Because it’s so difficult to control invasive species, Ritter and others
fighting the invaders focus on prevention.


Local volunteers and workers from the Wisconsin Department of Natural
Resources spend hours at boat landings. They urge people to clean their
boats, trailers, and fishing gear thoroughly when going from lake to lake,
that can keep unwanted plants and creatures from traveling along.

Forest Service Needs Better Planting Goals

The U.S. Forest Service reports more of the lands it manages
are in need of reforestation. But a Congressional watchdog agency
says the Forest Service doesn’t keep track of things well enough to
know exactly what needs to be done to do the job correctly. The Great
Lakes Radio Consortium’s Lester Graham reports:


For the last five years, the Forest Service has seen a trend. The amount of acreage that needs to be reforested has been increasing. But that’s all it really knows.


The Government Accountability Office says the Forest Service doesn’t have the right data to know how much forest needs to be restored, which sites take priority, or to even estimate a budget. The Forest Service says part of the reason it’s having a hard time figuring out reforestation needs is that it used to calculate reforestation by the amount of trees cut down.


But recently more natural disasters such as wildfires, insect infestations and disease have complicated the calculations. The GAO recommends adjusting Forest Service data collection and policies so that trees can be planted where and when they need to be.


If there’s a delay, the harvested areas become overgrown in scrub brush. And that can cost the Forest Service more money because it has to clear the land before it can be planted in the trees that benefit wildlife and the timber industry.

The City of Chicago and the U.S. Department of Agriculture are celebrating a small victory in their battle against an invasive pest. The Asian Longhorned Beetle arrived from China and is responsible for destroying thousands of hardwood trees in North America. The Great Lakes Radio Consortium’s Shawn Allee has more.


Chicago saw its first Asian Longhorned Beetle back in 1998. USDA and Chicago officials quickly destroyed more than fifteen hundred trees to stop the infestation. They also slapped a quarantine on the historic Ravenswood neighborhood, which prevented residents from removing tree cuttings from the area.


Now officials are lifting those restrictions, saying no one’s seen the bug in the area’s stately tree canopy for nearly two years. Joe McCarthy is the City of Chicago’s chief forester. He says a beetle hotline and a diligent press made the difference.


“There’s so much coverage of this thing, that the beetle is on TV, out in the papers, on front pages. And that’s how all the main infestations were found in the Chicago area.”


McCarthy points out that another Chicago neighborhood is still under quarantine.


The USDA is also fighting the Asian Longhorned Beetle in New York City and parts of New Jersey.
