States are failing to stop the spread of an invasive insect that’s killing
millions of ash trees. The GLRC’s Rebecca Williams reports:
People are spreading the emerald ash borer into new areas. The destructive
pest was first discovered killing ash trees in southeast Michigan four years ago.
Moving infested wood has spread the bug to Ontario, Ohio and Indiana. Now,
Illinois officials say the ash borer is infesting trees west of Chicago.
Researchers say moving infested firewood is the fastest way the beetle spreads.
Several states have banned moving firewood from quarantined areas. States
as far away as South Dakota are warning out-of-state campers to keep firewood at
Critics argue states are too lenient in enforcing the bans.
State officials say they’re struggling to keep up, as federal funding to
stop the ash borer is cut.
Researchers warn the ash borer could wipe out billions of ash trees if it’s not stopped.

Adult emerald ash borers lay eggs on the bark of ash trees. When the eggs hatch, the little larvae chew right through the bark and feast on the living tissue under the bark. The beetles cut off the tree's water and food supply. When the larvae become adults, they emerge from the tree, leaving a D-shaped exit hole.(Photo courtesy of the Michigan Department of

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
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
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
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
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

With about 30 bears on Stockton Island, some of them decided to swim for a less-
crowded scrounging area. So, this summer, campers reported bears rummaging through
their food on neighboring islands – forcing the Park Service to close a couple of
Apostle Islands Resource Specialist Julie Van Stappen says the bear population may be a
little crowded. And even though there has been an annual hunt of bears since the mid-1990’s, she doesn’t expect much help thinning out the bear population from hunters.
“Very few people do it. You have to get out to the islands and there’s no motorized equipment allowed, so it would be a very different hunt.”
Next summer, Van Stappen says instead of moving bears or closing campsites, the best
bet is to educate campers about storing food, and not attracting bears in the first place.
She says that would be the simplest way to end the close encounters of the bear kind on
the Apostle Islands.

Each year, tens of thousand of tourists flock to New York’s
Adirondack State Park… most of them heading straight for the High
Peaks, a rugged chain of mountains just west of Lake Champlain. More
visitors than ever before are climbing above the timberline and
environmental groups are concerned about rare alpine species that are
being crushed underfoot, damaged by campfires and tent sites. As the
Great Lakes Radio Consortium’s Brian Mann reports, a group called
Summit Stewards is working to protect this rarest part of the

In northern Minnesota, huge stretches of the popular Boundary Waters Canoe
Area Wilderness were severely damaged in a massive July fourth storm. One
hundred mile an hour winds flattened trees in a swath thirty miles long and
twelve miles wide. The emergency prompted the forest service to suspend the
rules against motors in the wilderness. The Great Lakes Radio Consortium’s

There’s been an increasing interest in wilderness survival classes recently,
sparked in large part by Y-2-K doomsayers. But survival training isn’t
new – for years, hikers, campers and other outdoor enthusiasts have taken
these classes to improve their skills…and along the way, often realize a
deeper connection with the environment. The Great Lakes Radio Consortium’s
