Climate change means faster growing
trees. Kyle Norris looks at ongoing
research that’s looking at how that
plays out:

Maybe you remember this from grade-school science: trees take in carbon
dioxide—that’s a gas emitted from burning fossil fuels. Then trees convert that
CO2 into oxygen. So with more carbon dioxide, trees are really taking off.

Wendy Jones is a research associate. She’s with Michigan Technological
University and she’s been studying young trees for the past eleven years.

Not only does carbon dioxide make trees grow faster, but warmer temperatures
help prolong the growing season. Jones says that could be good for the timber
industry.

“We could cut the trees sooner because they’re growing faster.”

For example, fast-growing aspen trees are used in everything from paper to
matchsticks. Jones says climate change could mean aspens could be harvested in
25 years instead of 35 years.

The US Forest Service has just released new
rules for managing the nation’s forests. Some
environmental groups say the new rules don’t do enough
to protect wildlife. They also believe it will mean more
logging on national forest land. Mark Brush reports:

The National Forest Service is required to draw up management plans for all 155
National Forests. Environmentalists say the new rules for drawing up these management
plans gut environmental protection standards.

The Center for Biological Diversity along with 13 other environmental groups have filed
suit against the Forest Service. They say the new rules will keep citizens in the dark.

Marc Fink is a lawyer for the Center.

“We’re talking about our public national forests. And I think it’s important to give the
citizens who are concerned about these forest the right to have meaningful standards to
hold their local officials accountable for when they’re proposing projects that might be
bad for the forests.”

Fink says, if the plan goes forward, logging could increase, or wildlife habitat could be
damaged without the public knowing about it.

The Forest Service says it’s just trying to take the red tape out of the forest planning
process.

Easing the Ash Borer’s Financial Bite

  • Homeowner Frank Wydra watches as logs from 16 of his ash trees get turned into lumber. All of the ash trees close to his house had to be cut down after they became infested with emerald ash borers. (Photo by Rebecca Williams)

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:

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.

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

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.

Recapturing Music’s Roots

These days a lot of modern music depends heavily on technology. Guitars are electric and beats electronic.

These days a lot of modern music depends heavily on technology. Guitars are electric and beats
electronic. But since ancient times human beings have found a way to make music with the
things they found in nature. The Great Lakes Radio Consortium’s Tamar Charney has the story of
one man who is helping his neighbors rediscover the roots of music:


In the woods behind Frank Youngman’s log home in Cadillac, Michigan there’s a small fire in a
fire circle. The smoke is wafting around logs that hang from the trees that surround the fire. It
curls around old car springs and break drums that also hang from the nearby trees. And big
hollowed out logs are propped up just inches off the ground.


On this cold, snowy Saturday there are five teenage boys and two adults banging on the logs and
car parts with sticks. And making music on what Frank Youngman calls his Sound Garden.


(music)


“I was out cutting firewood with our kids one day. And we were throwing it in the back of the
truck and it kept hitting each other. The logs were hitting each other. I just started noticing they
had all these different pitches and so I said, ‘kids throw ’em back out here.’ So we start laying it
out on the ground and we sorta constructed this crude xylophone. And pretty soon we were just
playing. I’d start a grove and they’d start playing and the four of us were on our knees around
these logs on the ground playing and we had a blast. After that, I kept thinking, wouldn’t it be fun
to have some instrument out in our woods here that when were walking by on the trail or skiing,
you could just stop and play a little bit.”


And eventually he built it. Youngman is a music teacher and band director, so he had an ear for
picking out the right logs with which to build his dream. Small logs are arranged to create
primitive xylophones and marimbas. Big logs act as bass drums. And the pieces of scrap metal
are miscellaneous percussion instruments. And any chance he gets, he’ll drag people out here to
play.


“Someone will start something just a click, cluck, cluck. Real simple little thing and then
someone layer in on top of it and it’s been fun cause they start to get the idea that we can slow
down and let it happen over a longer period of time and let it develop.”


He says after a while the people playing will start communicating and sharing musical ideas with
looks, nods, and beats.


(music)


As the rhythm gets going Ryan Newson and Mike Filkins emerge from their sullen teenage shells
and begin dancing and grooving to the beat. Like many people in town they first thought Frank
Youngman’s Sound Garden was really, really weird, but slowly they came around.


“You can’t explain the fun of playing it. You just have to go out there. The diversity of sounds
you get when hit stuff that you’re not even used to. When you play a drum set all day you just get
eight or nine different sounds you can play with, but with this it’s just a new set of sounds you can
screw around with and do what you want.”


The experience of playing the Sound Garden can vary from time to time. Frank Youngman says
night time playing has a different vibe from daytime playing. He thinks the Soundgarden’s best in
winter because the snow muffles the sounds and the woods are quiet, but then again other seasons
also have their appeal for instance warmer weather brings a chorus of frogs.


“In the spring, its great when the spring peepers. I’ve gone out by myself and you start hearing all
this sounds of springs birds and the peepers are just deafening at night sometimes and even they’ll
get a rhythm going and you get thousands of those things – rrrepperr rrrepper – they just get this
kind of pulsing rhythm and I’ve gone out and played with the peepers which sounds kind of
Crazy and maybe it is.”


Whether or not its crazy, the Sound Garden resonates with teenagers and adults alike, according
to 17-year old Mike Filkins.


I can imagine there will be people trying to build these now. This is just unbelievable. I was very
surprised how much it took off and how many people like it.”


And, in fact, a second Sound Garden has been built. After word got out about Frank Youngman’s
backyard one, the director of Cadillac’s Convention and Visitors Bureau suggested he create one
for the town’s new riverside Greenway. It’s just been finished in time to ring in the New Year
during Cadillac’s first night celebration.


(music)


“It’s a pretty primitive experience, you know, but I think it does kind of get back to musical roots
in some ways. It starts with rhythm – beating on a log – whether its signaling, talking over great
distances or just listening to each other and just responding.”

Habitat Harmed by Submerged Log Harvest?

Old growth logs left on the bottom of the Great Lakes continue to attract interest. The dense wood is prized by people who make instruments and fine furniture. A few states (Wisconsin, Minnesota, New York) have permitted salvage operations. But in Michigan, permits are on hold until officials resolve how removal of the logs affects fish habitat.

Old growth logs left on the bottom of the Great Lakes continue to
attract interest. The dense wood is prized by people who make instruments
and fine furniture. A few states (Wisconsin, Minnesota, New York) have permitted salvage
operations. But in Michigan, permits are on hold until officials resolve
how removal of the logs affects fish habitat. The Great Lakes Radio Consortium’s
Bob Allen has more:


The submerged timber has been abandoned since the heyday of logging in the
late 1800’s, but cold fresh water has preserved the wood. To retrieve it,
salvagers need two permits. One from the state, another from the U.S. Army
Corps of Engineers. Michigan has issued 12 permits. But the Army Corps
wants to be sure there’s no adverse impact on fish. Randy Claremont is a fish
biologist with the Little Traverse Bay Band of Odawa Indians. He’s been
documenting how fish use a proposed salvage pile in Lake Michigan off
the city of Petosky.


“Those logs… you know… at least every time we visited we saw fish
utilizing them because there’s very little habitat structure around so if
you remove those logs, you will definitely affect fish community
negatively.”


The Army Corps wants to be sure salvagers replace lost habitat with
rock or brush piles. Details are being worked out before permits
are issued. For the Great Lakes Radio Consortium, I’m Bob Allen.

Forest Service Sued Over Aspen Logging

The Sierra Club is suing the U.S. Forest Service to block logging of aspen in national forests in three Great Lakes states. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:

Transcript

The Sierra Club is suing the U.S. Forest Service to block logging of aspen on national forests in three Great Lakes states. The Great Lakes Radio Consortium’s Stephanie Hemphill reports.


The lawsuit asks a federal court to force the Forest Service to stop cutting aspen on its land in Michigan, Wisconsin, and Minnesota. The Sierra Club’s Anne Woiwode says the Forest Service favors aspen production at the expense of a healthy forest, and a healthy economy.


“When they choose to keep aspen at very high levels, they choose not to bring back forests that may be of greater economic value, may actually produce many more jobs than aspen does for the amount of wood produced.”


Woiwode says clear cutting aspen prevents white pine and hardwood forests from growing back.


The Forest Service says it manages forests for a variety of types and ages of trees, and doesn’t try to encourage aspen where it would not grow naturally.

Cordwood Homes Finding Their Niche

From a distance a cordwood building looks deceptively like it’s made
of
stone. But if you take a closer look you’ll see that what you thought
were stones actually are the ends of short logs laid widthwise to form
a
wall. In Europe, cordwood homes, sometimes called "poor mans’
architecture", have existed for over a thousand years. In North
America
the technique arrived with the early pioneers. Today, in the United
States, cordwood masonry is experiencing a renewed interest as
affordable housing because it’s cheap, easy to build, and energy
efficient. The Great Lakes Radio Consortium’s Linda Anderson has more:

Transcript

On the far end of a pond, in upstate New York, a group of people are working away, busy as

beavers. The comparison works nicely here, because like beavers, these people are building with

logs and a mud-like mortar.


To one side, a group of men vigorously mix mortar in a wheelbarrow. When they get it just right,

it’s delivered to another group of people whoa re busy stacking 6-8 pound logs. Carefully and

methodically, men, women, and children take the mortar and slather it around each sixteen inch

log. It looks like they’re stacking a wall of firewood. Only this wall is designed to last more

than one season. It’s designed to last a lifetime.


Rob Roy has been building with cordwood for over twenty years. He says there are areas in northern

Greece and Siberia where one-thousand-year-old cordwood structures still stand. Roy and his wife

Jaki discovered cordwood masonry during the energy crisis in the 1970’s.


“My wife and I just needed low cost shelter. This was back in 1975. We had worked on a log

building of heavy pine logs in Arkansas, and we found we just couldn’t heft these large logs by

ourselves. About that time there was an article in National Geographic that showed two pictures,

one interior and one exterior, of a cordwood wall… and we said jeez that makes sense. We can do

that. You are not handling anything more than a six to eight pound log end.”


No literature was available, so Roy and Jaki did their own research. They build their house,

learned from their mistakes, and wrote a book about it: The Complete Book of Cordwood Masonry

Housebuilding. Now they teach workshops at their home near Plattsburgh, New York and speak at

conferences. They’ve become missionaries of cordwood masonry.


“Cordwood makes use of waste wood which is unsuitable for other building uses. Logs which, for

example, are not strait enough to take to the saw mill. perhaps dead wood that has been fire

killed or disease killed on your property. I have even heard of people using driftwood or peeler

cores left over from plywood plants. All sorts of sources of so-called junk wood is perfectly fine

when you cut it into sixteen inch pieces.”


Roy says depending on how resourceful you are, materials can cost between ten to twenty dollars

per square foot. Roughly half of the cost of a standard frame building. Roy says a properly made

cordwood home will be energy efficient. It’s easy to heat in the winter and stays cool in the

summer.


“It has this wonderful combination of insulation and thermal mass. The mortar joint between the

log ends does not pass through the wall. There is insulated space. That space can be filled with

loose insulation such as vermiculite or pearlite. We use sawdust treated with lime. It’s equal to

about R3 insulation value per inch of thickness, roughly the same as fiberglass.”


Not only is cordwood masonry easy on the environment, Roy says it’s easy on people as well.

Light-weight logs allow an ease of construction that invites everyone to participate, including

Grandma. Although it’s probably unlikely you’ve ever seen one, Rob Roy says cordwood construction

is on the rise. Today there are three times as many cordwood homes in the United States as there

were a decade ago. Most can be found in Wisconsin and New York.


Eight years ago, in Cambridge, New York, Scott Carrino built a cordwood home with his family. Like

many cordwood homes, his is round. Colored glass bottles have been placed in patterns in the

walls. When the sun shines, it looks like stained glass. Carrino became interested in cordwood

masonry after reading Rob Roy’s book.


“I had actually visited Rob Roy pretty quickly after seeing this book, and saw some of his

buildings and really connected with it, and just fell in love with this building technique.”


TO keep his costs down, Carrino used lots of recycled materials, scavenging old windows, tubs and

sinks. He says many people look at his house and think it was an enormous amount of work. But his

friend, Jon Carlson, says that’s relative.


“It is a lot of work, but all building of homes is a lot of work. When you lay up a cordwood wall

its finished. Don’t have to come back and paint it. Don’t have to come back and side it. So not

only are you finished, but also you are creating something that is pretty maintenance-free.”


Cordwood builders, like Carlson and Carrino, love living in a home made of strong, natural

materials built by their own hands. Rob Roy says with the right materials and friends, anyone can

have that experience. And just like beavers, they’ll be experts in no time.
