People who make musical instruments know they have to start with a good piece of wood. Some guitar makers are worried that the woods they need for their instruments are becoming too rare. Tamara Keith has the story of how guitar makers are working with a group that fights to protect trees:

(sound of a factory)

There are people all over the Martin Guitar plant in Nazareth, Pennsylvania, doing fine detailed work. One man is chiseling out tiny pieces of wood to make the neck and the body of a guitar fit perfectly.

(sound of sanding)

Dick Boak does artist relations for Martin.

“So this is a D-35, this is what Johnny Cash played.”

He says this guitar’s deep resonant sound is all about what it’s made of. It’s a who’s who of rare and exotic species.

“Rosewood from East India, spruce from the Pacific Northwest, and mahogony probably from Peru or Bolivia. Those would be kind of the traditional woods for a guitar.”

Boak says logging is wiping out old growth forests where these types of woods are found.

“We would like it if every single supplier that we used was working in a sustainable fashion because that would ensure that our future as a guitar maker would be you know intact.”

So Martin Guitar has teamed up with the environmental group, Greenpeace.

Scott Paul is the group’s Forest Campaign Director and he’s super interested in the Sitka Spruce used in the Johnny Cash style guitar. We’re talking at the group’s office in Washington, DC. And he shows me where the spruce is used.

“This part on the top. This here is the soundboard. This is the species that really projects the sound.”

That Sitka Spruce comes from South East Alaska. Paul has been crusading to save the forests there for some time. He says Sitka Spruce has been logged as if there were no end in sight. Most of it is used for low-end construction materials. But when he found out the wood was used by the world’s leading instrument makers – he approached them.

“It was a very interesting meeting where you had the CEO of Gibson, and the CEO of Martin and Taylor and Fender all in the same room.”

The competitors said they were concerned about logging practices too. And the told Paul they’d work together on the issue.

“Let’s all go to Alaska and start talking to the logging companies that are providing you this product and figure out if we can do it better.”

So they did. This new Musicwood Coalition went to the Sealaska Corporation, which logs Sitka Spruce. And they’re now working with the company to save old growth trees for really valuable things like guitars.

Musical instrument companies are a very small part of the demand for old-growth wood. Paul says its less than 1%. But they can be very influential.

“They need the wood. They’re not the driving force. But their profile, and to be honest, their sex appeal is perfect. Not everyone likes Greenpeace, but red state, blue state, everyone loves guitars.”

(sound of guitar being tuned)

Dick Boak is tuning a guitar that’s just about ready to leave the Martin factory.

“Everybody has a song they use to tune.”

This guitar is part of Martin’s sustainable woods series. The hope is that someday all Martin guitars – and those of Gibson, Fender and Taylor too – will be made from trees grown and harvested in a way that makes sure the wood will be around for the long haul.

Interview: Why Private Forests Matter

There are 751 million acres of forest lands in the United States. More than half of it – 56% – is privately owned. Some of that land is owned by big timber companies. But the majority is owned by individuals and families. The American Forest Foundation represents those private landowners. Until last week, Larry Wiseman was CEO of the group. Lester Graham talked with Wiseman just before he left the organization. Wiseman says privately owned forests are at risk.

There are 751 million acres of forest lands in the United States. More than half of it – 56% – is privately owned. Some of that land is owned by big timber companies. But the majority is owned by individuals and families. The American Forest Foundation represents those private landowners. Until last week, Larry Wiseman was CEO of the group. Lester Graham talked with Wiseman just before he left the organization. Wiseman says privately owned forests are at risk.

Larry Wiseman: “One of the great paradoxes that most folks don’t quite get is that the largest part of the productive forest land in the United States is owned by families and individuals. Some 5 million folks who own more than 10 acres of land, some of them as long as 300 or 400 years – land has been in their family since before the United States was actually created.”

Lester Graham: “There’s a lot of concern these days because as the demand for things like newsprint, the demand for lumber is down because of the economy, there’s some concern that some pretty large tracts of land might be sold for things like development, just simply because they’re not making as much money off of this land. Is there a real risk of that?”

Wiseman: “Absolutely. The risk of conversion of forest land to development has accelerated over the past decade, to the point that we’re losing a little bit over one million acres a year. To put that in perspective, that’s about the size of the Everglades National Park every year. One of the primary pressures on forest owners, whether they own 1,000 acres or 100, is that they can’t do the kind of conservation work they want to do unless they have some cash. You know, cash is really the cornerstone of conservation when you’re talking about private property. People have to pay taxes, people have to buy liability insurance, people have to invest in the future of their forests, and if there’s no cash flow at the end, then it becomes very hard for them to say ‘no’ when a developer comes calling. This isn’t to say that all of these 4 or 5 million folks are growing timber for profit – very few of them actually do. But, by the same token, most of them have to develop cash flow, or, over time, it becomes very hard for them to keep their land as forests.”

Graham: “There has been suggestion that carbon offsets by planting more forest land, or that forest land owners should get some sort of compensation for the service that a forest would do – but there’s a lot of debate about the net-gain of a forest sequestering carbon dioxide. I’m wondering what your members feel about that issue?”

Wiseman: “There’s no doubt that on a net-net basis the forests in the United States currently absorb about 10% of the carbon dioxide upload as a nation.”

Graham: “Should your members be compensated for that?”

Wiseman: “Well, let me get to that in a minute. I believe they should be compensated. But our organization takes the position that healthy growing forests that are being managed for a suite of values – including carbon sequestration, water quality, wildlife habitat – provide a wide range of services to the public that the public doesn’t understand that it’s getting. These folks are volunteers; they’re providing clean water, cleaner air, wildlife habitat, outdoor recreation, and green space – for free! And, the great paradox is that the public doesn’t understand that they have a stake in the future of these forests, just as the owners do. Accordingly, that’s why our organization has long stressed the need to create streams of income that reward people for the stewardship investments they make that benefit the public as a whole.”

Tom Lyon is the Director of the Erb Institute of Global Sustainable Enterprise at the University of Michigan. He spoke with The Environment Report’s Lester Graham.

Recession Proof Construction

In the middle of a recession that’s

crippling the construction field,

there’s at least one sector of

industry that’s doing pretty well.

That’s “material reuse.” Taking pieces

of old buildings and using them in

new ones. Advocates say used materials

could save developers a heap of money.

Samara Freemark has the

story of one re-use company that’s both

green and in the black:

You’ve probably heard what’s going on in the construction industry
these days.

(news montage of housing crisis)

But in middle of all that bad news, there might be one bright spot.

“We’ve actually been expanding quite a bit. I guess it’s one of the
only times I’ve heard
of where that’s the case.”

That’s architect Brad Hardin.

He got interested in reusing building materials pretty early in his career.
He likes the way
the old stuff looked. And he likes the idea of saving resources. And
he’s also kind of
horrified by the tens of millions of tons of construction waste that get
tossed into landfills
every year.

But actually getting his hands on used materials, so that he could reuse
them- that turned
out to be a real pain in the butt.

“You know you’ll be literally going out to someone’s yard and getting
rained on, or
sorting through someone’s basement– it was kind of a hit and miss
process.”

A big part of the problem was simple logistics. Imagine you’re knocking
down an old
house to build a new one. You’d like to sell off whatever pieces of the
old building you
can. But how do you find someone to buy all that stuff? Where do you store
it while you
look for a buyer? And how do you ship the materials?

Harry Giles is a professor of green architecture at the University of
Michigan.

He says most developers don’t want to bother with all that hassle. In the
end, they usually
just end up bulldozing everything. Giles says that’s because there’s no
real secondhand
market for used construction materials- not like there is in a lot of other
industries.

“If you take the car industry, a lot of it is geared around the reuse of
materials. Not just
taking the car and crushing it, but taking it apart and finding useful
components on it.”

You know, like a salvage yard.

And that was the problem Brad Hardin wanted to solve – how to create a
secondhand
market for spare building parts. He figured that if he could do that,
reusing building
materials could actually end up profitable.

So last year he started a company called Planet ReUse. The company’s
website acts as
kind of a Craigslist just for reclaimed building materials. Buyers and
sellers can find each
other on the ‘net.

And Planet ReUse tests all material to make sure it’s up to code. That
way the buyer
doesn’t end up with, say, eight tons of rotten planking. And Planet ReUse
arranges all the
shipping- trying to hook up sellers to nearby buyers. That saves money and
fuel.

By removing those basic barriers, Hardin says his buyers save about 20%
compared to
buying new. And Planet ReUse still makes a profit.

And it’s also a start to reducing those millions of tons of landfill
waste.

So, what kind of stuff does he sell on the site?

“How much time do you have? Steel, flooring…”

It turns out there’s money in just about everything you can salvage from
a building.

Harry Giles says that cash is the key to cutting down waste.

“If people see that it’s a lucrative business to actually salvage
materials, that will drive it
much faster than concern for the environment.”

And it’s not just buildings. Remember President Obama’s inauguration
stage? Well, that
got torn down, and Planet ReUse is trying to get the pieces to New Orleans.
They’ll be
used to rebuild houses damaged by Hurricane Katrina.

It’s just one more way for Planet ReUse to prove that you can do good, be
green, and
make a little money too.

Rethinking Window Replacement

  • Jack Spicer of Preservation Chicago is on a campaign to save the venerable 'wood frame window,' like these on his Chicago home. (Photo by Shawn Allee)

Each winter presents some homeowners with a choice: whether to replace old,

again. Each year, more homeowners choose the replacement windows, often made from vinyl or aluminum. Shawn Allee found some historical preservationists want homeowners to think twice about that:

Each winter presents some homeowners with a choice: whether to replace old,
wooden windows with modern, energy-efficient ones before cold winds blow
again. Each year, more homeowners choose the replacement windows, often made from vinyl or aluminum. Shawn Allee found some historical preservationists want homeowners to think twice about that:

If you think century-old windows have to be rickety and leaky, Jack
Spicer would like you to come to his place.

He’s eager to show off windows on his Chicago two-flat, built in 1908.

“So, here’s an example of the way an old-fashioned wood window
looks from the outside a hundred years later. These windows are
longer-lasting and obviously better looking than any replacement window you
can find.”

It’s no surprise Spicer makes this pitch.
He’s with a group called Preservation Chicago, and he’s on a campaign
to save wood-frame windows from the onslaught of vinyl and aluminum-framed
replacements.

Spicer’s losing ground, even in his own neighborhood.

“This apartment building replaced their windows. The next building
replaced all their windows. If you look across the street at this huge
courtyard building, there’re about 48 units in there. Those windows were
fine, and those windows are now trashed. They went into a dumpster and are
now in a landfill somewhere.”

But if old wood-framed windows are so great, why do so many US homeowners
replace them?

“Somebody told them it would save them money if you put in brand-new
replacement windows. Everybody’s taught that – you read about it, you
see the ads. All the replacement window (companies) tell you, if you’re
American and you love your children, you’ll replace your windows. Well,
we’re getting over that now, I hope.”

Spicer insists replacing your windows is not an environmental slam dunk.

He says if old wood-frame windows are properly sealed and have storm
windows, they’ll hold heat almost as well as replacements.

I ask Spicer for numbers on this, and he sends me to Mike Jackson, with
Illinois’ Historic Preservation Agency.

“Several years ago, Vermont as a state did a study and they looked
at repairing windows, adding storm windows, replacing windows, and what it
really came down to was, how leaky are your windows? If they were
reasonably tight, there wasn’t a lot of savings to replacing your windows
at all.”

Jackson says a new furnace or insulation are better pay-offs, and
replacement windows often last just a few decades.

“We’re throwing away items that lasted for a hundred years with
simple technologies and replacing them with more complex things with
shorter life spans. In our line, the reason they call them replacement
windows is because you have to keep replacing them.”

Well, people in the replacement window industry don’t take kindly to
this.

One rep told me the short life span of replacement windows is overblown –
high quality ones last longer.
And he told me, if energy prices rise in the future, replacement windows
become more competitive.

So, is it worth replacing old, wooden windows?

“There’re many factors and that’s why it’s, in our opinion,
not so clear-cut.”

Christian Kohler studies window technology at the Lawrence-Berkeley
National Laboratory.

He says replacement windows are better on energy, but it could take decades
to get a good payback and by that time, you might need to replace them
again.

Anyway, Kohler says there’s an alternative.

If your wood windows are in good condition, you can add storm windows that
have what’s called a “low – E” coating.
The coating helps retain heat.

“It’s applied to glass and it’s virtually invisible. It
doesn’t have a color or anything.”

Kohler says if preservationists want to keep wood windows around on account
of their looks or long-term value, it still makes sense to crack down on
leaks and get good storm windows.

It doesn’t make sense to waste energy on account of beauty when you
don’t have to.

Communities Welcome Wilderness

  • Eric Fernandez of Oregon Wild says wild areas still allow for a lot of activity - "just leave your chainsaws and bulldozers at home." (Photo by Sadie Babits)

More than two million acres in nine states could soon become permanent wilderness. Congress is expected to vote on the plan today. Sadie Babits recently visited one of the sites, Mount Hood in Oregon:

Transcript

More than two million acres in nine states could soon become permanent wilderness. Congress is expected to vote on the plan today. Sadie Babits recently visited one of the sites, Mount Hood in Oregon:

A steady stream of traffic runs through the small town of Sandy, Oregon every day.

It’s known as the “Gateway to Mount Hood.”

This used to be a town of lumberjacks. The timber industry was king here.

And a wilderness designation means no logging.

“It wasn’t that long ago that this was a mill town so for the city council unanimously support wilderness is an interesting thing.”

That’s Scott Lazenby. He’s the town’s city manager. He says in the past a wilderness proposal would end up in a Paul Bunyan sized tussle.

But Lazenby says the city council saw real benefits to having wilderness in Sandy’s backyard.

“We do have a watershed that our city water comes from. It’s important to protect that and part of that watershed would be protected by the wilderness bill.”

Not only that. Lazenby says these days, it’s not timber – it’s tourism that brings money to Sandy.

“Even though the number of people who can go into wilderness is relatively limited, the presence of wilderness is a very positive thing.”

Under a massive bundle of bills now before Congress, 127,000 acres surrounding Mount Hood would become wilderness along with other sites across the nation.

“Right now we’re standing in White River Canyon and in the winter this is a really popular place for cross country skiing, snow showing.”

That’s Eric Fernandez. He’s the wilderness coordinator for Oregon Wild – a conservation group out of Portland.

He says a wilderness designation still leaves a place open to all kinds of activities hunting fishing camping.

“You just have to leave your chainsaw and bulldozer at home.”

Fernandez says, yes, this entire area will mean clean drinking water, and wildlife protection.

“But in this instance, the reason I’m so excited about protecting this area of White River Canyon as wilderness is because it has the world’s best sledding habitat.”

Yep, he said sledding – like tobogganing. There’s nobody sledding today.

But, we did bump into Jeff McKnown, who’s out skiing.

“It’s great to come here on the weekday when no one is here.”

McKnown says he loves the trees and the snow so bright it hurts your eyes.
He’s been escaping to White River canyon when he can for the last fifteen years.

“You know when you have a wife and five kids these moments are pretty precious.”

The law that makes wilderness designations possible has been around since 1964. There are more than 700 wilderness areas in 44 states.

But Oregon has lagged behind. Even conservative Idaho has more wilderness than the more progressive Oregon.

Mike Matz thinks that could change. He leads the ‘Campaign for America’s Wilderness’. It’s been pushing for the new wilderness designations before Congress.

“It’s really become amazingly so a motherhood and apple pie issue. This is something that Republicans and Democrats alike have gotten strongly behind.”

And from Oregon’s Mount Hood, to rolling hills in West Virginia, from red rock country in southern Utah, to sand dunes along the Great Lakes – it looks like Congress will preserve two million acres more as wilderness.

Twenty years ago this year, the
country watched its oldest national park
go up in flames. Looking back, scientists
believe the 1988 fires of Yellowstone
National Park were the signal fire of
climate change. Researchers have been
working ever since to understand this
relationship between climate and wildfire.
Sadie Babits reports on two scientists
searching for clues to ancient climates,
using trees as their guide:

Jennifer Pierce wears work boots as she plows down a steep slope in a
ponderosa pine forest.

(sound of walking, twigs breaking)

Her blonde hair is tucked up under her Boise State bronco cap, but it keeps
sneaking out. She has to keep brushing it back under. She and her
colleague David Wilkins are professors who work for Boise State
University’s Geosciences Department. They’re in the middle of tall pines in
a forest just outside of Boise, Idaho. Suddenly she’s crashing across the
brambles and heads for this tree.

“Oh that’s a great one! Wow! Sweet!”

She drops to her knees and shows me how this tree has been scarred by
fire.

“You see this little V shaped cat face here at the bottom of the tree that’s
blackened? So during a fire when the bark of the tree gets damaged that
preserves a record of the fire as a scar on the tree.”

Pierce says since the tree has annual growth rings, she can tell when the
tree got burned.

It’s one way Pierce and Wilkins reconstruct the fire history of this forest.
It’s a key to understanding how climate has affected forest fires in the past.

“I think as we move into a likely warmer and drier future, it’s going to be
increasingly important to understand the relationship between climate and
fire.”

She says climate is the primary control for wildfires. As the West warms,
there’s less control. Recently, that’s meant a lot more wildfires.

(popping sound) “There you go!” (sound of a drill bit going through the tree
with sound of birds and forest)

David Wilkins is twisting an auger into the tree.

“It’s a good upper body workout!” (laughs)

It’s a way to take a sample of the rings of this tree. Within a half-minute,
Wilkins’ auger is stuck. The tree is rotten inside. An eight-inch core is all he
gets.

(sound of drill bit coming out of the tree)

Jennifer Pierce takes a look at this sample Wilkins twisted out. The rings –
some light, some dark – reveal just how the tree has responded to moisture
and temperature.

“If you have a tree that kind of is at the edge of its comfort zone so to
speak, it will be more of a sensitive recorder of those environmental
stresses. See this one looks pretty good.”

Tree rings aren’t the only clue these scientists use to reconstruct historic
climates.

(scraping sound)

“I didn’t bring my big shovel. I kind of feel naked without it.”

Pierce scrapes away dirt and she finds bits of charcoal. She can sometimes
use charcoal for radio carbon dating. But these won’t do.

“But, um, I wouldn’t use them for dating because you want to make sure
that the charcoal is stratographicly in place and that you haven’t had
critters burrowing and mixing things up.”

Charcoal can be dated much further back than the tree rings. It helps
Pierce and Wilkins understand what happened here thousands of years
ago. With samples from other scientists, they’ll get a snapshot of ancient
climate and how it affects wildfire.

And possibly determine what climate change will mean for forests in the
future.

Only Trees Can Prevent Forest Fires?

New technology might help the US
Forest Service detect fires in remote areas
more quickly. Lester Graham reports:

A chemical reaction makes batteries generate electricity. There’s a ph difference
between trees and the soil around them. MIT researchers say they can use that
chemical difference to generate a tiny amount of electricity.

Andreas Mershin and his MIT colleagues say it’s just enough power to trickle charge
sensors that read temperature and humidity. Then they send that data to the U.S.
Forest Service so it can determine the risk of fire.

“The advantage comes from the fact you no longer need to be going to very remote
locations and changing batteries all the time.”

The Forest Service will be testing these sensors next spring. They cost about one-tenth
of other sensors that need batteries. So it could mean more sensors in remote
locations. That way the Forest Service could have a better idea of if and when it needs
to put fire equipment near hot, dry areas.

Red-headed woodpeckers used to
be just about everywhere east of the Rocky

red-headed woodpeckers is about half of
what it was fifty years ago. Stephanie
Hemphill reports volunteers
are working on a new project to get people
to help red-headed woodpeckers. They’re
encouraging landowners to let dead or dying
trees stand rather than cut them down:

You can’t miss Red-headed Woodpeckers. They have long beaks,
bright red heads and snowy white breasts. And if you go to the right
place, you can find a lot of them.

“Somebody told me that there was Red-headed Woodpeckers up
here, so I walked five minutes, and there was a Red-headed
Woodpecker, and it flew into a hole in a tree, and I says, ‘wow, this is
easy.’”

Lance Nelson first visited the Cedar Creek Ecosystem Science
Reserve about a year ago.

“And then I came up this year and found 8 nests. But the young
make a lot of chattering, so you can usually tell where the nest is.”

Today they’re not hammering on trees – the sound most of us
associate with woodpeckers – but they’re doing plenty of chattering.

This reserve in southern Minnesota looks a lot like how much of the
Midwest used to look.

There are clumps of big oak trees here, separated by open areas of
native grasses, shrubs and wildflowers. The biologists call it an oak
savannah.

And there are Red-headed Woodpeckers everywhere – about fifty of
them on this 500-acre patch of ground.

“There’s a red-headed, and he’s got a baby with him. God, they’re
beautiful. They are so beautiful.”

That’s Chet Meyers. After a career as a college professor, he’s now
in charge of an effort to make more places where Red-headed
Woodpeckers can build their nests and raise their young.

If they can figure out exactly what the woodpeckers like so much
about this place, maybe they can come close to reproducing the
same conditions other places.

Chet Meyers is marking every tree where the woodpeckers have
nested.

“See these two trees to the left, go to the right-most one, it forks, and
there’s a broken-off snag up there, looks like a ‘Y’. That’s where the
babies were sticking their head out a couple weeks ago. It was really
cute.”

Once the trees are marked, the group will catalog exact descriptions
of each tree. They’re hoping to come up with a profile of the perfect
home for Red-headed Woodpeckers.

“And we’re going to measure the diameter of the tree, how high the
nest cavity is, the species of the tree, is it alive or is it dead, so we
can get some data on what seems to be the preferred habitat.”

Once they’re pretty sure they know what the woodpeckers like, they’ll
reach out to land owners. They’ll to try to get them to leave dead and
dying trees standing.

That could work on old abandoned farms, where there are trees and
open spaces. Or in cemeteries. Or around golf courses.

“If our theory – see, this is all theory – if our theory is correct, the golf
course replicates an oak savannah and there should be birds there.
So, that’s what we’re hoping.”

And Meyers says helping woodpeckers means helping other wildlife
too.

“The woodpecker is called a primary nester, it digs the cavity. But
flying squirrels, mice, snakes, bluebirds, tree swallows – there are lots
of other animals that are secondary nesters. They can’t drill the hole.
But they live there. So what we’re trying to do is preserve the habitat
so the woodpeckers drill the hole and when they leave, something
else will come in and live in it.”

The researchers think if you have dead or dying tree, that could be a
home for a Red-headed Woodpecker. But usually homeowners are
worried the tree could fall and damage something, Meyers says you
can cut off the top and some of the bigger branches and leave the
rest of the tree standing. They think the red-headed woodpecker will
be just as happy.

Westward Ho for the Ash Borer

The emerald ash borer has eaten through
millions of trees in the US and is spreading
west. Erin Toner has more:

For six long years, the tiny metallic-green emerald ash borer has been a killing machine,
starting with millions of ash trees in Michigan and Canada, and then munching its way
into 10 states.

It was recently discovered in Missouri, and now, it’s in Wisconsin.

The prognosis is not good.

Darrell Zastrow is with the Wisconsin Department of Natural Resources.

“Our forests are not typically resilient against non-native species and that is true for
the emerald ash borer. It is generally considered to be a poster child for invasive
species.”

Officials in Wisconsin are doing what everyone else has done – restricting the movement
of firewood and telling people how to protect their trees.

Some promising treatments to fight the emerald ash borer are being tested, but so far,
nothing has worked at keeping the insect from spreading west.

An invasive plant called Garlic Mustard is
taking over forests in the Eastern half of the country,
and it could be causing long term damage. Julie Grant
reports that some people are getting smart in their
efforts to get rid of Garlic Mustard:

Brad Steman spends a lot of time in the woods. He likes the serenity.
But as we walk through this park, he winces. The entire forest floor is
carpeted with one plant and one plant only: Garlic Mustard.
Thousands of them. The thin green stalks are as tall as our ankles.

Steman calls it “the evil weed.” Its triangle-shaped leaves shade out
wildflowers, so they don’t grow. Even worse, Steman says Garlic
Mustard poisons baby trees.

“So a forest filled with Garlic Mustard you will see very little
regeneration of that forest, very few seedlings, small trees. So
looking down the line, once those large trees start dying off there’s
nothing to replace them. And that now is the greatest threat to our
Eastern forests.”

Steman says every year Garlic Mustard is spreading farther into the
woods. Anywhere the ground is disturbed.

“So here’s a big stand of it along a trail. This is typically where it
starts. This is thick. This is a healthy stand. There’s potential there
for an explosion. So we should probably pull some. I’ll pull some;
you don’t have to pull any.”

Thank goodness he’s doing it – that looks it looks like tedious work.
Steman crouches down and starts pulling them out of the ground,
roots and all. He sprayed herbicide on some of it, and so far this
season he’s filled 35 big garbage bags with Garlic Mustard plants.
He’s sick of weeding. But it doesn’t look like he’s made a dent here.
All along the Eastern half of the US and Canada people are pulling up
Garlic Mustard from parks and just throwing it away. But some
people don’t like this approach.

“All these people are very shortsighted when they’re doing that.”

Peter Gail is a specialist in edible weeds.

“They’re not looking for other alternative uses – creative ways to use these plants that would be
profitable, that would be productive.”

Gail says: “If you can’t beat ‘em, eat ‘em.” People brought Garlic
Mustard to the US in the mid-1800s because they liked it, to eat. And
they even used it for medicine. Yep. That same nasty weed.

Gail says today Garlic Mustard just needs an image makeover.
Some weeds have become big stars in the cooking world. A few
years ago Purselane was just an unwanted vine, with its fleshy, shiny
leaves matted to the ground. Now it’s known as a nutritional
powerhouse, and is the darling of New York and LA eateries. Gail
wants that kind of fame for Garlic Mustard.

“This is a Garlic Mustard Ricotta dip, Garlic Mustard salsa, stuffed Garlic Mustard leaves – these are all things you can do with this stuff. It’s fantastic!”

Garlic Mustard seeds taste like mustard, the leaves taste like garlic
and the roots are reminiscent of horseradish.
Gail says people should go after Garlic Mustard in the parks, but then
they should take it to farm markets to sell.

“My normal statement is that the best way to demoralize weeds is to
eat them.
Because when you eat them they know you like them and they don’t
want to be there anymore, and so they leave.”

(blender sound)

Today Gail decides to blend a pesto using the early spring leaves.
He picks every last Garlic Mustard in his yard to make a batch.

“Well there it is, garlic mustard pesto. And it isn’t bad, is it?”
Julie Grant: “It’s delicious.”

For The Environment Report, I’m Julie Grant.
Gail: “I’ll use that on ravioli tonight.”
