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.

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:

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.

Big, public aquariums spend a lot of money to make fish look like
they’re at home in the wild, but lately some aquariums are showing fish
that are out of place. The GLRC’s Shawn Allee looks at one aquarium’s
effort to give them the spotlight, too:
The federal government’s spending millions to keep Asian Carp out of
the Great Lakes. Biologists worry Asian Carp could devastate the lakes’
ecosystem. Recently, though, several carp were brought within sight of
the Great Lakes, and biologists are happy about it.
Chicago’s Shedd Aquarium is on the shore of Lake Michigan. It’s
holding an exhibit of Asian Carp and other alien invasive species.
Curator Kurt Hettinger captured the aquarium’s carp during a trip on an
Illinois river.
“They’re literally jumping, sometimes over the bow of the boat,
sometimes smacking into the side of the boat. I just looked behind me
and was amazed to see all these fish jumping in the wake of the boat, and
to this day, I’m still stunned by this.”
And Hettinger’s more than just stunned. He’s worried.
Asian Carp are an invasive species, basically … pests that crowd out
native fish, and that river where he caught them hooks up to Lake
Michigan.
Again, Asian carp haven’t made it to the Great Lakes, but more than one
hundred and sixty other invasive species have arrived and are breeding
quickly.
One example’s the zebra mussel. At first, scientists worried about how
much money it could cost us. Zebra mussels multiply so fast they can
block pipes that carry cooling water to power plants. But now, we know
the zebra mussel’s disrupting the lakes’ natural food chain.
In other words, invasive species are a huge economic and ecological
nuisance. That’s why the Shedd Aquarium started the exhibit.
“The public I think has seen enough stories about the damages and the
spread and the harmfulness, but those stories are not very often coupled
with solutions.”
That’s ecologist David Lodge. He says the exhibit tries to show how
people spread these species around. Lodge points to one exhibit tank. It
looks like a typical backyard water garden. It’s decked out with a small
fishpond, water lilies, even a little fountain shaped like an angel. It looks
pretty innocent, but Lodge says plants and fish you buy for your own
water garden could be invasive species.
“All those plants and animals that are put outside, then have an
opportunity to spread. Now, it doesn’t happen very often, but with the
number of water gardens, it happens enough so that they are a serious
threat to the spread of species.”
Birds or even a quick flood could move seeds or minnows from your
garden to a nearby lake or river.
The Shedd Aquarium’s not alone in spotlighting invasive species.
Several aquariums and science museums are also getting on board. For example one in
Florida shows how invasive species have infested the Everglades.
Shedd curator George Parsons went far and wide for inspiration.
“I was in Japan last year when we were planning this, and I just
happened to stumble across one of their aquariums and they had an
invasive species exhibit, except that they were talking about large mouth
bass and blue gill. You know, something that is our natives. So, it was
kind of ironic to see that out there. It was kind of neat.”
Like us, the Japanese take invasive species seriously. Back in 1999 the
humble Midwestern Blue Gill created a national uproar. Turns out, they
had taken over ponds throughout the Emperor’s palace, and how did the
bluegill get to Japan?
Probably as a gift from a former Chicago mayor. Apparently, the mayor
thought blue gill might make nice sport fishing in Japan. It was an
innocent mistake, but it’s just the kind of mishap biologists want all of us
to avoid from now on.
A tree-killing beetle continues to spread through the region. The beetle has left millions of ash trees in its wake. Now it’s spread into northeast Indiana and will cost one city there much of its natural beauty. The Great Lakes Radio Consortium’s Jeff Bossert reports:

A tree-killing beetle continues to spread through the region. The beetle has left millions of ash trees in its wake. Now
it’s spread into northeast Indiana and will cost one city there much of its
natural beauty. The Great Lakes Radio Consortium’s Jeff Bossert
reports:
A survey of ash trees in Decatur by the state’s Department of Natural
Resources shows the emerald ash borer has been wreaking havoc there
for some time on some trees, as long as 4 or 5 years. So, the city recently
announced it would spend 1-million dollars to cut down about 15-
thousand of them.
The ash borer slowly kills trees by making tunnels under the bark and
cutting off the food supply.
City Forester Dwight Pierce says the trees are almost entirely
infested. He hopes this move will end any concerns of the ash borer
showing up elsewhere in the state.
“We don’t want to let it spread out of our city and get into adjoining
cities, and spread farther south in the state. We’re still hoping we can
control it here before it gets down to south of Indianapolis and it turns
into a whole forest again. We obviously don’t want to let it get into
that.”
Pierce says the beetle likely came from firewood brought in from
infected areas in Michigan or Ohio… and he hopes residents of Decatur
heed warnings about moving firewood across state lines.

American Indians have been making baskets from the wood

American Indians have been making baskets from the wood of black ash trees
for hundreds of years. Now, they see that tradition threatened by a beetle. The
emerald ash borer has killed millions of ash trees in Lower Michigan over the
past few years, and Indian basket makers are preparing for the day when their
grandchildren may no longer find black ash. The Great Lakes Radio
Consortium’s Bob Allen reports:
(Sound of museum)
The Anishinabe believe the black ash tree is a gift to their people, and they say
its carried them through many hard times. The story of the baskets is part of a
display in the Ziibiwing Center at the Saginaw Chippewa Reservation in
central Michigan.
Judy Pamp is assistant director of the Center, and she remembers how
important baskets were when she was growing up.
“If we ate it was because there were baskets to sell or trade, and it went from
that being the thing that sustained us to where now it’s more of a an art and a rare art,
and that you do in limited quantities.”
Pamp comes from a long line of basket makers, and she’d like to pass on the
skills to her granddaughter, but she says the baskets aren’t the most
important thing… rather it’s a sense of connection among the generations.
“You know the whole family pulling together, the whole community pulling
together to help one another out… that everybody was important and
everybody had their role.”
Some family members may be good at one part of the basket making, and
there’s plenty of work to divvy up. First, there’s going into a swamp to find a
black ash tree, cut it down and haul it out.
(Sound of pounding)
Then, there’s peeling off the bark, and pounding the wood into strips, called
splints, for baskets. All that can take 25 hours of hand labor. Then, it’s
another 6 or 8 hours to weave a basket. Without the trees, basket makers worry
they may lose that closeness of working together.
The emerald ash borer isn’t on tribal lands yet, but it’s in
two neighboring counties. Scientists say it’s only a matter of time before the
beetle invades the reservation and wipes out the ash tree. The invasive pest got
to the U.S. in cargo shipped from Asia. Despite quarantines the bug continues to
spread because people move infested firewood, timber or landscape trees.
Deb McCullough is an entomologist at Michigan State University. She
concedes ash trees in Lower Michigan are goners.
“Took me a while to get my mind around that. You know we’re going to see
somewhere probably in the neighborhood of four hundred million ash trees in the forests
of lower Michigan that eventually are going to succumb to emerald ash borer
unless something really amazing happens in the next few years.”
McCullough says they’re looking for a way to help trees resist the insect, or a
predator to keep it in check, but it might be years before a solution is found.
So, the tribes are looking at their own ways to deal with the ash borer.
(Sound of splint pulling)
One idea is to harvest a whole bunch of black ash splints for baskets and freeze
them to use later. That would keep basket making going for a while.
(Sound of basket maker)
Another plan is to collect and save seeds from black ash trees.
Basket maker Renee Dillard says someday maybe trees can be replanted from
seed, but she says that means forty or fifty years before any wood is
harvestable, and she doesn’t think she’ll be around then to teach her
grandchildren how to choose the right tree and pound out the splints.
(Sound of pounding)
“As a people, we’re pretty resilient and we can adapt to change. It’s just that we’re
losing an important part of that whole black ash process, and I don’t want my great
grandchildren to just make baskets. They need to understand the whole process because
it’s done carefully and prayerfully.”
Dillard follows the old ways. She lays down tobacco as an offering of thanks for the tree,
and she believes this calls her ancestors to witness her use of the gift.
The Anishinabe don’t know why the emerald ash borer is taking their trees at
this time, but their tradition teaches for every hardship there will be an answer
and something to balance the loss.
