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 – 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.”

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?”

“It’s delicious.”

Biomass Power’s Footprint (Part 2)

Biomass power is the new-fangled alternative energy source that uses a pretty old technology: basically, you just burn plants, usually wood, for electrical power.

Many states are looking into biomass power because they have plenty of wood and sometimes wind or solar farms meet resistance from neighbors.

For a while, Massachussetts looked like it would give biomass power a big boost.
Shawn Allee found the state could change its mind.

A guy named John Bos gives me a tour of an old lumber mill.

It’s in Western Massachussetts, in a town called Russell.
The mill’s almost in ruins.

“So you can see this … it looks like movie set out of a bad , bad-guy movie.”

“Definitely. Watch your footing there .. ”

This factory used to turn wood into lumber, charcoal and paper.

Bos’ brother and other investors want to give the place a new life … but wood will still play a key role.

“We are walking into the site of what will be Russell Biomass.”

The Russell biomass plant would be a power station that burns wood to generate electricity.

It’d burn through half a million tons of wood each year.

And if you think that’s a lot of trees going up in smoke, Bos says the plant will use mostly waste wood.

“Our wood will come from discarded pallets, stump removal from development. Road side trimming. Every year there’s road-side trimming to keep utility lines clear. There’s a lot of waste wood out there.”

This is controversial talk in Western Massachussetts.

Critics of biomass power don’t trust the idea that local supplies of “waste wood” will hold out since investors are planning five biomass power plants.

Chris Matera is one critic.
Matera shows me what he fears could happen if projects like Russell Biomass come through.

He takes me to forest that surrounds a long, thin reservoir.

The forest filters rainwater and keeps the reservoir clean and clear.
The reservoir happens to supply water to the Boston metro area.
Anyway, Matera shows me there’s logging here.

“We’re looking at big stumps and rutted out muddy areas on a steep slope that actually dr ain into the watershed eventually. It’s not gonna help the water quality. This is a place you’re not even allowed to cross-country ski to protect the watershed. A lot of places you’re not even allowed to hike.”

These trees were NOT cut for biomass power, but Matera fears new biomass plants will use up cheap waste wood …
Then, they’d resort to logging like this to keep producing electricity.
And the water quality in reservoirs, streams and rivers would suffer.

There’s been plenty of heat between biomass proponents and their critics.

One sticking point is whether Massachussetts should subsidize biomass power in the same way it does other renewable power sources, like wind and solar.

The state hired an outside consulting group called Manomet to help it decide.

“We’ve been asked by the state of Massachusetts to answer some basic fundamental questions about woody biomass energy.”

John Hagan is Manomet’s president.
Hagan’s supposed to answer whether there’s enough waste wood or any kind of wood to supply biomass plants planned for Massachussetts.

He says his group’s not entirely finished, but …

“I think if four, fifty megawatt plants went in, they’d almost certainly have to pull wood from beyond the boundaries of the State of Massachusetts.”

Hagan says this doesn’t necessarily mean forests in the state will suffer … his group’s not finished with its report, after all.

But he thinks it’s good Massaschussetts is questioning whether biomass deserves extra financial help.

Hagan says states are subsidizing biomass without thinking through all the effects … not just on local jobs … but also forests, and local air and water pollution.

Is Wood Biomass Just Blowing Smoke? (Part 1)

State governments often mandate power companies to buy alternative energy.
They figure it’s worth having everyone buck up and pay extra since these don’t contribute carbon dioxide emissions that change the climate.

But what energy sources should make the cut?

Shawn Allee found one is getting lots of scrutiny.

Bob Cleaves heads up the Biomass Power Association.

He spends a lot of time pitching the idea that electricity made by burning wood is worth government help.
After all, he can’t sell the idea of biomass on price.

Electricity generated from wood had to compete with coal and natural gas and it became very difficult to operate these plants on a profitable basis.

Cleaves says other alternative energy sources are expensive, too, but biomass has extra benefits …
He says try running solar panels at night – biomass power plants run 24-7.

But Cleaves admits he’s got explaining to do when it comes to carbon emissions.

You know, from burning wood.

when you burn something you release CO2 …

For years, Cleaves could follow-up with a simple argument.

He’d just run through the carbon cycle idea you might recall from high school.

You know, you burn trees.
That releases CO2.
Then, as trees re-grow, they absorb that same carbon again …

These are carbons that are recycled into the environment in a closed-loop fashion.

This argument often won out.
Many states give biomass from wood subsidies, since they considered it carbon neutral.

The US House came close to doing the same thing last year.

But lately, biomass’ rep got into trouble.

Well, the carbon issue came up in the fall as a result of an article published in Science magazine.

The title of the article was “Fixing a Critical Climate Accounting Error.”
It challenged the idea that biomass power from wood or anything else is always carbon neutral.

Critics now use the article’s arguments against biomass subsidies.

“This policy is intended to reduce carbon emissions and it’s doing the exact opposite.”

This is Jana Chicoine, an anti-biomass activist from Massachussetts.

She says, sure, trees you cut for power now will grow back and then re-absorb carbon.

But not soon.

“It will create a pulse of carbon emissions that will spike for decades. Policy makers are telling us we are in a carbon crisis and that we have to reduce carbon emissions now.”

So, Chicoine says it makes no sense to subsidize biomass technology.

It’s going to harm public policy on clean energy. Those funds should be going to the truly valuable contributors to the energy problem like wind and solar, conservation and efficiency.

Well, Chicoine and other biomass critics won a temporary victory in Massachusetts.

The state was leaning toward subsidizing biomass power, but it held off a final decision.

It’s waiting for advice from an environmental consulting group called Manomet.

President John Hagan says people expect a simple answer: would a biomass industry in Massachusetts be carbon neutral or not?

“The last thing you want to hear a scientist say is, it’s complicated, but I’m afraid it is in this case.”

The latest research suggests some biomass power operations can be carbon neutral while others won’t be.

The best operations would use tree trimmings or waste wood like sawdust. That keeps more trees in the ground … absorbing carbon.

Biomass power plants prefer to use waste wood anyway, since it’s cheap.
But Hagan says maybe more biomass plants will all chase the same scrap wood.

Prices will rise … and suddenly standing trees start looking cheaper.

It’s like a puzzle, when you push on one piece, eighteen other things move.

Hagan says the bottom line is that biomass can be carbon neutral … if subsidies and policies are precise.
He says policies should work like scalpels.

But often, they’re simple … and work more like big axes.

Greenovation: The Great Floor Debate

The popular eco-friendly products are not always the best solution. Lester and Greenovation.tv’s Matt Grocoff drop in on Matt’s neighbor to help him with his hardwood floor dilemma.

Transcript

In home improvement projects, the popular eco-friendly products are not always the best solution. Lester Graham has the story of a home improvement intervention.

Kevin Leeser was not happy with the floors downstairs in his one-hundred year old house.

KL: “Well, we’ve lived here five years and just over the five years they’ve started to get grayer and you can tell that the finish was –in the high traffic areas—you could tell where we were walking it looks like we were hamsters walking through this place.”

LG: “This is maple, right”

KL: “Pfft. Yeah, that’s what they tell me.”

Kevin toyed with the idea of finishing the maple floors… but that sounded really involved.

And then the in-laws visited during the holidays.

KL: “My mother-in-law was like ‘Why don’t you get new floors.’ (laugh) And I was like well, yeah, it would be easier, ‘cause the things I was concerned about were sawdust, and ‘cause I have a newborn, just dirtying up the house and figured just getting some clean stuff, cutting it outside, sticking it down and be done with it.”

LG: So, wanting to be eco-friendly, he thought he’d put down bamboo flooring. Bamboo is renewable and it grows fast… and it’s pretty popular these days.

Then his neighbor stopped by. Matt Grocoff… the eco-friendly home improvement guy with Greenovation-dot-TV who had some –eh—thoughts about Kevin’s plan…

MG: “And, I, like, practically smacked him in the face and I said ‘What are you thinking? This is a gorgeous floor. Go rent yourself a sander or even hire someone for a few hundred bucks to strip the floor and then refinish it.’”

LG: So…You’re not a big fan of bamboo?

MG: “Bamboo is a great product if you have to do something new. You have to ask a question: do you need that new product or do you have something that works now and just needs to be renewed.”

Oh, yeah. Reduce. Re-use. Recycle. So, Kevin’s wife, Lauren and their baby were away for a few days. Kevin rented a sander… …and then started looking for an eco-friendly sealant for his maple floors. Matt had an idea for that.

MG: “Kevin’s using a natural oil from BioShield which is a mixture of tung and linseed oil that is so easy to use. It’s easier to use than even a low-VOC or zero-VOC polyurethene finish and easier to maintain in the long run.”

And in the end… renting the sander, buying sanding pads, buying the floor sealant, paint brushes and all that stuff… ended up costing Kevin about HALF of what it would have if he put down bamboo. Not a bad deal.

But… the big question… what did his wife, Lauren, think of the refinished old floors.

LM “It looks absolutely beautiful and we didn’t have to get new floors. Win, win. We love it. Beautiful.”

Matt Grocoff says he was sure Kevin and Lauren would be happy, because he did the same thing at his house.

MG: “The first thing that I did when we finished with our floor is I took a glass of red wine when we were celebrating and I poured half a glass of red wine on the floor and my wife was like ‘What are you doing!’ And I was like, look, we’re going to spill wine on it eventually, let’s see what happens now. The wine beaded up on the floor. We took a little sponge, wiped it clean and it’s gorgeous, five years later.

LG: “That’s Matt Grocoff with Greenovation-dot-TV. Thanks, Matt.”

MG: “Lester, this is always so much fun. I’m glad to be doing it.”

LG: “That’s The Environment Report. I’m Lester Graham.”

The US government is spending

these facilities are years behind what
they are already doing in Europe –
especially in Germany. In the first
part of our three-part series on biofuels
in Europe, Sadie Babits takes us to one
German plant that makes green energy
on a massive scale:

We’re in Eastern Germany where crews work on what looks like brew vats.

(construction sound)

These monster tanks remind me of vats for brewing beer, except these vats will brew energy from fermenting rye, manure and bacteria.

“Basically, we’re standing here in front of the biogas and bio fertilizer production area. The big fermenter is for the biogas production.”

Oliver Lutke is our tour guide. He’s really a chemical engineer for Verbio. The company is one of Germany’s largest commercial producers of biofuels. Lutke’s been involved in turning this ethanol facility into a plant that makes ethanol and biogas. That’s methane.

“We convert everything into energy by using biological processes. This combination biogas and bioethanol production plant isn’t existing in the world.”

That’s what Verbio claims anyway. The company buys grain from some four-thousand farmers in the region. The grain gets turned into biogas and ethanol. Verbio then turns the minerals from making these biofuels into fertilizer.
That goes back to the farmers for their crops.

“We’re closing the loop to the farmer converting all the carbon to energy and the minerals going back to the farmers as fertilizer which is growing the plants used to extract the energy.”

Lutke says the company has the technology to make this industrial sized plant profitable. That baffles skeptics because it costs a lot to make green energy. You have to buy the grain. And the actual process of turning that grain into fuel can be really inefficient. By the time you’ve made one gallon of biofuel, that gallon of oil is cheaper.

Jan Liebetrau isn’t convinced Verbio has the answer. He researches bioenergy and its potential in Germany.

“If you put lots of energy into the system and you get bioethanol you’re putting more energy in than you get out.”

So making bio ethanol costs energy, which defeats the whole purpose of producing it in the first place. Lutke doesn’t see it that way. He says Verbio has the technology to make biofuels without losing energy. And because the company’s process is more efficient, Lutke says they’ve cut down on greenhouse gas emissions.

“We emit 200,000 tons and the plants we are using will eat off 180,000 tons and that’s a closed cycle.”

It’s not perfect, but there’s less greenhouse gas being released than, say, from an oil refinery. Lutke is convinced bio energy will play a big role in cutting greenhouse gas emissions.

Germany, and Europe for that matter, have become leaders on this. Germany wants to be the first industrialized nation to be powered entirely by renewable energy – a goal Germany could reach by 2050, well ahead of the U.S.

Timber is an important revenue stream for some areas. But from New York to
Washington State, forest managers say timber thieves have been pretty
active. Last year in Alabama, they stole more than a half million dollars
worth of trees.

State forester Linda Casey says landowners might have
earmarked that money to pay off the mortgage or send their kids to college.

“If they have timber stolen they just lost the only chance that
they have to achieve whatever goal that they had designated to use this
money for.”

Foresters say reckless timber thieves also damage wildlife habitats.

States
are cracking down. This month, Alabama will decide on tough new rules that
would make it a misdemeanor to even step on private forest land without
permission.

There are places where some wildlife
that once thrived, are now gone. In
Wisconsin, the Pine Marten has been
wiped out. The shy animal looks a bit
like a ferret. Pine Martens are members
of the weasel family. Barbara Jean Johnson
went out with researchers to see how
they’re bringing Pine Martens back to
northern Wisconsin:

You probably have never seen a pine marten. But I’m spending the day with two guys who spend weeks at a time looking for them. They work for the Wisconsin DNR. We’re actually in a county in northern Minnesota. We’re crammed into a Ford Ranger pickup, driving on the back roads to check trap lines. We’re looking for Pine Martens in Minnesota that will be released in northern Wisconsin.

Pine Marten’s were wiped out or extirpated in Wisconsin over the last hundred years. The Marten’s were in trouble once European settlers moved in. A combination of forest fires reduced animal habitat. Already too many of the animals were trapped for their pelts. But then the Great Depression hit.

“Trapping was a valuable commodity. Fur prices were high and many farmers and farm boys feed their families off their trap lines, and given that there’re weren’t many regulations, or limited regulations, and the high value, I don’t doubt that they over harvested, as well.”

That’s Jeff Wilson. He’s on the frontlines of this varmint capture mission. He and his partner Dan Haskell are seeking to right some of the past wrongs. Dan and Jeff are fun guys. They love the wilderness and they like to chat. The only downside to our little expedition is the smell that permeates the cab. I didn’t say anything, but it smells like skunk.

“Now you do admit, you do smell a little skunk essence in here, do you not? We do our best you know. we shower everyday, but we have been getting a few looks at the grocery stores and the places we’ve been shopping in your Grand Marais community. We hope we haven’t offended anybody.”

These guys us a skunk scent to lure Pine Martens to live-traps. They love the scent. And, they’re not the only ones. Apparently this skunk compound is used in the famous French perfume Chanel No. 5. Some of their colleagues have actually used the perfume as a lure when trapping lynx in Canada.

“However, Chanel No. 5 is like $90 an ounce. (laughs) So we don’t use it.”

Dan and Jeff don’t want just any kind of marten. They already have all the males they need. They want females. As we make our way from trap to trap we catch male after male – seriously, five males – and no females.

“My wife says it’s because they are smarter, but I think it’s because they have a much smaller home range – maybe a half a mile to a mile. In contrast, males cover around two to three miles. You’re just going to get more males. If you set a trap line and spread it out, there’s going to be about two or three times more possibility of a male capture than a female capture.”

(sound of animal screaming)

Catch six, and we’re all hoping it’s a girl. But they have to check to make sure. Marten’s may be small, but they’re certainly not known for being cuddly.

Jeff coaxes the marten head-first into the corner of a laundry bag. He puts a tight hold on its head while Dan peels back the bag to check the genitalia. Once they know they’ve captured a female, they sedate her and run through a series of basic tests to collect data. They also give each animal they take home a name.

“This one is obviously going to be called ‘Barbara’ after you, our colleague. (laughter) You’re a breath of fresh air – literally. (laughter)”

Yeah, they’re a little lonely out in the field. Not a lot of people spend much time with them – smelling a little like skunk and all. And they’re away from home for extended periods of time. But, all in all, they both enjoy what they do and find real meaning in it.

“We can restore what we’ve mismanaged in the past and it’s inspirational for me to see there’s no doubt there’s a niche for this animal there. This animal is a really important part of biological diversity and I’m really happy I can participate in that.” For The Environment Report, I’m Barbara Jean Johnson.

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.

(sound of a beetle)

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.

(sound of sawing and pounding)

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.

When somebody says a natural area, dose everybody have the same thing in mind? Some might see a park with baseball fields or a golf course as a natural area. But natural area means what it looked like for hundreds or thousands of years before humans started changing the landscape. Sometimes, that natural landscape was changed so long ago, when it’s restored to the way it looked oringally, it’s not very familiar to the people who live there now. Shawn Allee talked with some people who disagree about the idea of restoring natural areas:

If you go to the Bunker Hill Forest Preserve just outside Chicago, you find picnic spaces, bike trails, and woods – acres of woods.

If it’s the wrong day, though, a security guard will turn you back from the woods.

Guard: “Closed off for a while? It’s closed off for a while. They’re doing a controlled burn – they’re burning that field over there.”

Man: “What are you doing exactly? Burning?”

Guard: “Controlled burn.”

Forest preserve workers in sooty, yellow fire suits are burning brush and trees.

They say soil tests show this land was once savanna – a kind of grassland with a few trees mixed in.

They’re trying to restore it to that original landscape.

Volunteers help out with this restoration, but a small number of people want to stop it.

“Everything they burned today is area they’ve cleared over the past two years. We’re opposed to cutting our urban forests.”

Bathsheba Burmin shows me the site – after it’s cooled.

She wants me to see what it takes to turn woods into savanna.

Burmin: “It’s a little muddy, so…”

Allee: “It’s hard not to notice.”

(sounds of walking through mud)

Allee: “This place is being actively transformed.”

Burmin: “Yes.”

Allee: “You can see brush piles moved around, trees have obviously been cut because you can see the stumps, and obviously they burned just today.”

Burmin: “What it does is tell the story of what the restructuring of an ecosystem looks like.”

Burmin and a few of her neighbors have protested the transformation of these woods into savanna.

Some don’t believe this was ever grassy savanna in the first place.

Burmin says, even if it was savanna – it’s not now; it’s woodland – and she regrets losing the trees.

Burmin: “If you’re not familiar with the site and you hear there’s an increase in grassland species you must be doing something wonderful. Nobody talked about what happened to all the woodland species. The reason you have an increase in grassland species, but that’s because you took out all the forest.”

Habitat restoration can be violent.

It can involve poisoning or burning unwanted plants or maybe killing animals like deer that graze on more desirable plants.

Wildlife managers use restoration techniques all the time, but on occasion critics like Burmin ask tough questions about it.

When that happens, people like Stephen Packard rush to its defense.

“Now we’re standing in a place where all the brush was cut last year.”

Packard heads the Chicago chapter of the Audobon Society.

He’s offered to show me some restored savanna, about ten miles north of that Bunker Hill spot.

It looks kinda familiar.

Allee: “There’re stumps and sticks everywhere.”

Packard: “Is this ugly or is it not ugly? Here’s my perspective on it. To me it’s like a bunch of broken eggshells after someone made an omelet. I think this is a beautiful thing to see the first stage of recovery. It is stumps, it is bare ground, but from doing this, I know certain plants will start to come up and keep developing.”

Packard says no one restores savanna because they like chopping trees.

It’s just that some plants need open space and light – like in a savanna. Dense woods create too much shade for them.

He says if we let some natural areas literally run wild, a few aggressive species take over, and the rare ones lose out.
