That’s the sound of mountain pine beetles hard at work, laying
eggs beneath a tree’s bark. That kills the tree.

Here in Colorado’s Rocky Mountains,
two million acres of pine trees have been killed.

But the same destruction caused by the bugs has also created an
opportunity.

The beetles introduce a fungus that stains the wood a unique
blue. And that’s caught the attention of Colorado’s woodworkers. They’re using the wood for everything from furniture to decking.

Outside Boulder, a company called Kitchens by Wedgewood is using the wood for
cabinets.

Wedgewood President Jim Ames says his company started working
with the timber three years ago.

Despite the drop in the housing market, Ames says customers like the blue stained finish.

“People are starting to ask for it more and more. Again, as
we get into this green movement, everybody wants to see what all those
dead trees in Colorado look like when they’re turned into a cabinet door.”

Ames says, with so many trees being killed, there will be enough timber to make beetle
wood cabinets for the rest of his lifetime.

New Front Line in Ash Borer Fight

The emerald ash borer is killing millions of ash trees, and the destructive beetle continues to show up in more and more places. Rebecca Williams reports one state is cutting down trees even though the beetle hasn’t been found there yet:

Transcript

The emerald ash borer is killing millions of ash trees, and the destructive beetle continues to show up in more and more places. Rebecca Williams reports one state is cutting down trees even though the beetle hasn’t been found there yet:


The emerald ash borer has killed more than 20 million trees in several Midwestern states and Ontario. The beetle kills trees by eating through the living tissue underneath the bark.


But it takes a tree a few years to show signs of infestation. So foresters sometimes have to cut down trees and strip the bark away to look for the beetles.


Wisconsin officials say they’ll be cutting down about 6-thousand trees to look for the ash borer.


Jane Larson is a spokesperson for the Wisconsin Department of Agriculture.


“Well for many years we used to think, well if it gets here, but I think we’ve realized it’s not a matter of if but when it’s going to arrive.”


Larson says officials hope to get a jump start on containing the ash borer if they find it. The borer has cost homeowners, states and industries tens of millions of dollars.

Easing the Ash Borer’s Financial Bite

Homeowners and cities are losing many of their big, beautiful shade
trees. An invasive insect called the emerald ash borer is killing ash
trees in Michigan, Ohio, and Indiana… and making neighboring states
worried. About 15 million ash trees are dead or dying leaving behind
enormous bills. The GLRC’s Rebecca Williams reports some people are
trying to ease the loss by salvaging lumber from their dead trees:


(sound of birds chirping)


The emerald ash borer ruined Frank Wydra’s summer plans. His 10 acre
lot is full of ash trees… more than a hundred. Wydra built an
elaborate shade garden underneath a cluster of ash trees, right next to
his brand new house. Right around the time he and his family were
ready to move in… they noticed the trees were looking sick.


“They were here when we bought the property and we sort of built the
property, the house around these trees. I had no alternative but to
cut these down, because they were so close to the house.”


Wydra says he’s losing a lot more than a shady backyard. He says the
emerald ash borer is costing him at least 10-thousand dollars. That’s
the cost for cutting the trees down, grinding the stumps out… and
planting new trees. But there’s one part of that cost he’s not too
upset about: the 100 dollars an hour he’s paying to have his dead ash
trees milled into lumber.


(sound of portable sawmill at work and running under)


“It’s got a very close grain that allows you to mill it without too
much trouble. It’s nice stuff. I wish I hadn’t built all my
cabinets.”


Frank Wydra’s already got more board feet of ash piled up here than he
knows what to do with. But he says he’d rather pay to have the logs
turned into something he can use than pay to have them hauled away.
Wydra hired a company called Last Chance Logs to Lumber. Chris Last
brings his portable sawmill to sites like this one, and with some help
from his family members, he loads the logs onto the sawmill and slices
the bark away.

(sound of rolling logs under)

“We’re required to take at least a half inch below those two layers,
you’ll see as we open this up… just the characteristics of the log will
determine that… usually we take off more than that.”

By stripping away the bark and a half inch of the wood beneath the
bark, Chris Last is making sure none of the emerald ash borers will
survive.
Researchers have found that carefully debarking ash logs is one way to
make the wood safe to use.

Chris Last created his business four years ago, shortly after the ash
borer was first identified as the pest killing trees in the upper
Midwest. Since then, he says some of his customers have gotten pretty
creative.

“The neatest thing is a gentleman that was an architect, when he had
the tree cut down he left the log standing for about 10 feet, and what
he ended up building was an old English cottage house on top of this
stump. I guess he reads up there, but it’s beautiful, it’s absolutely
gorgeous, every bit of it, every stick is made out of ash.”

Last says he’s seen a church craft new pews from their ash trees, and
he’s worked for cities that have built picnic tables from ash, but for
the most part, homeowners and city officials are just starting to
figure out how to use the lumber from their dead trees.


Jessica Simons is with the Southeast Michigan Resource Conservation and
Development Council. It’s a nonprofit group that’s giving out grants
to promote the use of ash wood. Simons says the idea’s catching on,
but there are some real obstacles.


“To be honest, it can be a tricky proposition. What’s easier: go to
Lowe’s and buy lumber, or to have your dead trees removed, hire a
sawmill, have the mill come out, allow wood to dry and then be able to
finish it into a product.”


But Simons says milling ash trees into lumber can sometimes save money.
Right now, most homeowners and cities chip up their dead trees and have
the chips hauled away. Both of those steps cost money. Simons says by
milling trees on site, you can cut back on the disposal costs and end
up with wood for a new dining table or a bunch of park benches.

Jessica Simons points out that not all parts of the ash trees can be
turned into products. She says most of the ash wood waste from
Michigan and Ohio gets trucked up to a co-generation plant in Flint,
Michigan, where the wood chips are burned to generate electricity.
Simons says that is a good use for the lower-value parts of the trees,
like stumps or branches.


“But the only thing we’ve argued throughout this is that a number of
great logs were in that wood as well, and when you think about the
value that wood can have as lumber or a higher value product like a
railroad tie, it’s worth much more than what a truckload of fuel is
worth.”


Simons admits re-using dead ash trees won’t cut back a lot on the
tremendous costs that homeowners and cities are bearing to deal with
the ash borer, but she argues that turning ash trees into flooring or
furniture could generate a little bit of money instead of just adding
another line onto the bill.

Millions of ash trees are being killed by a tiny green beetle called
the emerald ash borer. Some people say all those dead trees shouldn’t
be considered waste, so they’re recycling the trees into lumber. The
GLRC’s Rebecca Williams has more:


Most of the time, when cities cut down their dead ash trees, they chip
up the trees and have them hauled away. Some people are trying to find
uses for the lumber from the trees instead.


Jessica Simons is with the Southeast Michigan Resource Conservation and
Development Council. It’s a nonprofit group that’s giving out grants to
promote the use of ash wood. Simons says cutting ash logs into lumber
can sometimes save cities money, because they can cut back on the cost
of chipping up and hauling away the trees:


“They’re also aren’t paying for lumber for other city projects because
they’re just paying for that wood to be milled and then they have all
the wood they need for projects like park benches or picnic tables or
sideboards for their trucks.”


Simons says because it’s a relatively new concept some cities have had
trouble finding room to store all of the lumber they’ve made from the
trees, but she says the idea’s still starting to catch on, as cities
look for ways to cut costs.

Protecting Trees From Lawnmowers

It’s that time of year when the sound of lawnmowers and weed whackers fills the air. A
tree expert says trees that are bumped by mowers or scraped by string trimmers can be
seriously damaged or killed. The GLRC’s Fred Kight has the story:


If your trees could talk, they might be saying “keep that lawnmower away from me!”
Trees that are wounded by lawn equipment become vulnerable to disease, decay and
insects. Urban Forester Ann Bonner says often just one swipe with the trimmer can slice
into a young tree’s thin bark, killing it in no time:


“Some easy ways to protect your trees would be plant shrubbery, or ground covers,
flowers around the base of your trees, or simply mulch them. Planting mulch around
your trees not only will keep the grass away, but it will also help moderate the moisture
and climate extremes that are pretty common.”


Another way to protect trees from lawnmowers and string trimmers is to place plastic
tubing around the base. For the GLRC, I’m Fred Kight.

More Trees Lost to Emerald Ash Borer

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.

Beetle Threatens Anishinabe’s Ash Trees

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.

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.

Beech Bark Disease Survivors Are Resistant

Researchers might have a partial solution to the problem
of beech bark disease. The disease has killed millions of beeches
in the Northeast and is advancing on the woodlands of the Midwest.
The Great Lakes Radio Consortium’s Tracy Samilton has this report:


Beech bark disease happens when an insect infests beech trees. Then the
trees are killed or crippled by an opportunistic fungus. Where the
disease has struck, researchers found one to five percent of the trees had
natural resistance to the insect.


Jennifer Cook is a USDA Forest Service researcher.Her experiments found that seeds from two resistant parent trees produced progeny that are also resistant. That could set the stage
for reforestation and even pro-active plantings.


“People can plant them before the disease gets there and
therefore lessen the impact on their forest lands.”


Cook says if you’ve got a big beautiful beech tree you want to save, you
can scrub the tree’s bark with insecticidal soap once a year. Of course
it would be impossible to scrub every beech tree in the forests.

Banking on Birch Bark

A start-up company is banking on birch bark. The papery bark can be used for more than baskets and canoes.

But Native American healers have been using birch bark for years, and some of them are worried about the supply. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:

A start-up company is banking on birch bark. The papery bark can be used for more than baskets and canoes. It’s used in skin creams, and scientists are studying it for use in treating skin rashes and even cancer. But Native American healers have been using birch bark for years, and some of them are worried about the supply. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Have you ever noticed – walking in the woods – those cylinders of bright white bark, lying on the forest floor? Those are the remains of a birch tree. The inside of the tree rots away quickly, but the bark lasts much longer.


“The birch tree has some incredible defense mechanisms that protect the tree from weather, from rain, from sun, keep the moisture in, keep moisture out.”


David Peterson knows birch trees pretty well. He was a top manager at the Potlatch Paper Mill near Duluth, Minnesota. The plant processes thousands of trees every day, and burns the bark to make steam.


“I always was interested in trying to come with a way of using some of these low value waste streams generated from pulp paper mills and other places, it seemed like such a horrible waste, to take these really interesting compounds and put them in a boiler for boiler fuel.”


Peterson’s new company, NaturNorth Technologies, plans to make something worth a lot more than boiler fuel. The company has patented a process to extract large quantities of a chemical, betulin, that gives birch bark its anti-bacterial and anti-fungal qualities.


Mill workers remove bark from a tree that’s harvested for lumber or paper-making. It’s shredded into pellets, and put through a chemical process that extracts the betulin. It ends up looking something like salt.


“Here’s a sample of betulin, and you can see how bright and white it is. It’s got a chalky feel when you touch it.”


Apparently, what birch bark does for the birch tree, it can also do for human skin – protect it from the assaults of the physical world. Betulin is already used in some creams and cosmetics, but NaturNorth plans to be the first company in the world to market it on a large scale.


The idea of selling lots of betulin from birch bark makes Skip Sandman nervous. He’s a Native American traditional healer for the Mille Lacs Band of Ojibwe. He uses birch bark for medicine. He says it’s a pain-killer and blood-thinner and can be used for intestinal disorders.


“Fortunately, when people use it for medicines and stuff, one small tree does go a long way. But you might have to travel 15, 20 miles to find the right type of tree.”


Sandman says the bigger trees – ten to twelve inches in diameter – have a bigger supply of the properties he uses in medicine. And lately he’s had to go farther to find those big trees. He says that’s because timber companies have cut down so many of the big trees and now they’re working on smaller and smaller trees.


“But you see the logging trucks go by, and they’re just whacking down everything. Well they think it’s only a tree. But when the trees are gone, then what do we do?”


Sandman says in the Ojibwe creation story, each plant and animal promised to help people in some way, and birch trees offered their healing qualities. He says it’s important to use them respectfully, and not for profit, but only to help people. He says he approaches the tree with an offering of tobacco.


“I will put tobacco down and ask and talk to that tree, because it is alive.”


The folks at NaturNorth are hoping to make money from birch trees, but they’re also excited about helping people. David Peterson says he gets letters from people who want some betulin to treat a skin condition.


“When you get those letters, you can’t help but to feel that somebody out there that’s gonna benefit eventually from these compounds, I think it’s quite sobering and humbling.”


NaturNorth has started marketing betulin to cosmetics companies, and scientists are studying betulinic acid for its disease-fighting potential. Peterson says it’ll be several years before NaturNorth generates a profit.

Setting Traps for Emerald Ash Borer

The emerald ash borer has been destroying ash trees in Michigan, Ohio,
Illinois, Maryland, and Ontario – and the bug is spreading. Now,
agricultural officials in Michigan are developing an early warning
system. By detecting the insects early, they hope to slow or even
prevent its spread. The Great Lakes Radio Consortium’s Tracy Samilton
reports:


Forestry agents will be designating a number of so-called trap trees in
every township in Michigan. The ash trees will act as sentinels. A
strip of bark will be removed from the trees, which stresses them and
makes them attractive to insects. A sticky substance called tanglefoot
will then be applied to the trees to catch the borers. Kara Bouchay is
with the Michigan Department of Natural Resources.


“Part of the struggle with having a borer that you can’t see most of
time because it’s underneath the bark, is when it’s in a low level
population, it basically flies under the radar. So the trap tree is a
way to bring it to a single location to detect it.”


If borers are found on a tree, all ash trees within a half-mile will be
destroyed to contain its spread. Bouchay says if the early detection
system proves itself, it will likely be implemented in other states as
well.
