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.”

No Paperless Office Yet

When the computer-age took
off in the 1990s, lots of
people thought we’d use a
lot less paper. But that
hasn’t happened. Julie Grant
reports on why environmentalists
are so concerned about all
the paper we’re still using
in our offices and homes:

Allen Hershkowitz knew that the computer revolution wasn’t going to lead to a paper-less society. He’s been a scientist with the Natural Resources Defense Council, the NRDC, since people first started using email.

“Very early on, even at NRDC, we started to see people printing out documents that would otherwise have been retyped or emails that shouldn’t have been printed out.”

Hershkowitz says Americans use 7-times more paper than the average person on the planet. And computer printouts are just the beginning. Packaging, cigarettes, tissues and toilet paper – Hershkowitz has seen firsthand the devastation the demand for all that paper it’s causing.

“Ancient forests, forests that have existed way before Christ and Moses and Mohammed, for 10,000 years, are being cut down for toilet paper. A product we use for 2-3 seconds. This does not make sense.”

Hershkowitz says this deforestation causes more global warming pollution than all the trucks, buses, planes and ships in the world combined. He scoffs at products like 3-ply toilet paper, and compares using them to driving a gas-guzzling Hummer.

In Europe and Asia, much more of the toilet paper is made from recycled paper. Americans get beat up in the international press for allowing their delicate buttocks to devastate the world’s forests.

For five years, the environmentalist group Greenpeace held protests against the Kimberly Clark Corporation, maker of Kleenex tissues, for cutting Canada’s Boreal Forest and other forests around the world for its products. Greenpeace’s campaign against Kimberly Clark took late night political comedian Stephen Colbert by surprise.

Colbert: “Now for starters, who knew toilet paper came from trees? I always assumed it came from cartoon bears.”

Greenpeace recently ended their protests. Kimberly Clark agreed that by next year 40% of the fiber in their tissue products would come from recycled paper. But while environmentalists support this concession, it does not please Mr. Colbert.

Colbert: “Have you seen recycled toilet paper? Environmentalists, I swear, if you take away my plush toilet paper, I’m just going to use the next softest thing – spotted owls.”

Most paper makers aren’t opposed to using recycled material in their products. Dan Sandoval is an editor at the publication Recycling Today. He says most cardboard boxes and newspapers are already made from recycled paper.

And that recycled toilet tissue? He says that’s usually made from old office paper. The stuff we use for printing and writing. But a lot of times office waste is all thrown together – and isn’t clean enough to be recycled into something new.

“You know, when you’re collecting it all together here, you’re going to get some telephone books, some post-it notes and things like that that people are throwing together. Plastic windowed envelopes. Some of that stuff is like, it’s kind of iffy on that. So you get more material, but the quality goes down.”

Sandoval says that means the paper mills have to invest in a lot more cleaning equipment. And some times it costs more than just cutting down trees. Still, he says the trend for companies around the world is toward more recycled content. Environmentalists want paper companies to move faster.

And they say consumers also need to do their part. In the office, they want people to print less, and at home, they’re asking people to stop buying toilet paper that’s 3 layers thick.

The US Forest Service has
announced it will not increase
fees for ranchers who let their
animals graze on public lands.
Rebecca Williams reports that
makes some environmentalists mad:

Ranchers have to pay to let their cows, sheep and goats eat plants on public land. This year, that monthly fee is staying put at $1.35 for each so-called “animal unit.” For example, that’s a cow and her calf, or five sheep.

Taylor McKinnon is with the Center for Biological Diversity. He says livestock grazing is one of the reasons species like the desert tortoise and Mexican gray wolf are in trouble. And he says taxpayers are subsidizing livestock grazing, and then paying to fix the damage it creates.

“We have the U.S. Fish and Wildlife Service whose recovery programs are spending tremendous amounts of money to recover species who have been imperiled by livestock grazing.”

McKinnon says raising grazing fees would increase costs for ranchers.

No one at the National Cattlemen’s Beef Association was available for comment.

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.

Officials from every country in the
world have gathered in Copenhagen
this week to build the
framework for a global climate treaty.
One of the goals is to slow the
destruction of forests in developing
countries. Those forests process and
store massive amounts of carbon dioxide.
Ann Dornfeld reports:

Preserving forests will be a huge debate in Copenhagen. Poor countries want wealthier countries to compensate them for not cutting the forests for lumber and to convert it to farmland. To find out why that might be important, you have to visit a place like this peat forest on the Indonesian island of Sumatra.

(sound of the forest)

Forests like this one are home to orangutans, Sumatran tigers and Asian elephants. But these forests may be more important for what lies beneath their marshy floors. The peat is composed of thousands of years’ worth of organic material. Indonesia’s peat forests are storage units for much of the world’s carbon. And they’re being destroyed at an alarming rate.

Not far down the road, Greenpeace Indonesia campaigner Bustar Maitar looks out on a charred landscape. You’d never know a forest stood here just a few months ago.

“Is the no more ecosystem here. No more forest here.”

Only a few burnt tree trunks are standing. Sour smoke curls up from the blackened ground. Maitar says this fire has been burning for a month.

“Fire is coming from not from in the top of the ground, but the haze is coming from inside. It means it’s the underground fire, especially in peatland. And underground fire is very difficult to handle.”

Indonesia’s peat forests are rapidly being logged, drained and burned in order to clear the land for tree farms and palm oil plantations.

The peat can be dozens of feet deep. When it’s burned, the carbon it’s been storing is released as carbon dioxide into the atmosphere. All of that burning peat has made Indonesia the world’s third largest emitter of CO2.

Until recently, industrialized nations topped the list of greenhouse gas emitters. Now the United States shares that shortlist with developing nations like China, India and Brazil. As these countries industrialize, demand for timber and open space has stripped many of their forests bare. But leaders of developing countries insist their nations should be allowed to do what it takes to build their economies – even if that leads to climate change.

Paul Winn works on forest and climate issues for Greenpeace. He says the only alternative is for wealthy countries to pay developing countries to slow their emissions.

“If the industrialized world is serious about climate change, it’s essential. It just has to be.”

Winn says wealthy countries have pledged 45 billion dollars so far to help poor countries reduce emissions. But he says that’s just a start.

“If you compare that to what the industrialized world spent on protecting its banks and its financial institutions during the financial crisis, it’s a pittance. And it’s far more essential that they do it now. Because these forests are threatened, and the emissions that go up into the atmosphere are going to come back and bite the industrialized world if they don’t fund its protection.”

Some of the funding plans on the table at Copenhagen would still involve drastic changes to the world’s forest ecosystems. The UN’s current plan would give pulp and paper corporations in Indonesia carbon credits to convert peat forests into acacia plantations.

Winn says that’s the opposite of what needs to happen. Greenpeace and other environmental groups want industrialized countries to fund a moratorium on logging.

One complicating factor is the rampant corruption in many developing countries.

“It is a concern. And I would imagine that’s why many of the industrialized countries haven’t committed to funding.”

Winn says a thorough verification process would ensure that if countries allowed logging, they’d have to repay donor nations.

Winn is in Copenhagen to promote forest protection in the developing world. He says he doesn’t expect anything major to come out of this conference – but hopefully it will lay some groundwork.

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.

some scientists want all this forest talk

Stuart Pimm is a biologist at Duke University. He says in Copenhagen, rich countries might agree to pay poor countries to stop cutting forests. Pimm says that’s great but not all forests are equal.

“Some forests have more carbon in them than others, and some forests have more species in them than others.”

Pimm and other biologists say carbon pricing alone might mean carbon-poor forests get cut – even if they’re home to lots of animal species. They want negotiators to somehow tweak any climate agreement.

“So we should be encouraging countries not to burn their forests, but we should encourage them not to burn the forests that are so biologically rich.”

Climate negotiators could take up Pimm’s idea next month in Copenhagen.

Urban forest researchers say cities
need different kinds of trees. Having
too many of the same kind of trees
encourages pests. Lester Graham reports:

Pests have already wiped out native trees such as chestnuts, elms and now ash.

James Kielbaso is a forester with Michigan State University. He says native trees are great but, one of his students has found some cities are too reliant on them.

“An urban tree population should not consist of any more than ten or fifteen percent of any one species. He’s finding the trees that are most over-used tend to be our native trees.”

In some cases, maples make up 30% of a city’s trees. That means if a disease or a pest hits maples, a city could lose a third of its urban forest.

Kielbaso says people should plant tree species not already in the neighborhood and a few hardy foreign species could help diversify a city forest.

Today we hear a lot of news calling
this “the worst recession since the
Great Depression.” Tonight, PBS
begins airing a series of documentaries
from American Experience called
“The 1930s.” Lester Graham reports
the series looks back at the Great
Depression:

The documentaries in “The 1930s” series look at the stockmarket crash, the Dust Bowl, and the government’s response – such as President Franklin Roosevelt’s New Deal.

Robert Stone directed one of the five documentaries. He looked at the Civilian Conservation Corps – the CCC. Stone says it was the first of Roosevelt’s work programs, but it also tackled the biggest environmental disasters.

“We’d spent hundreds of years just chopping down all of the forests in this country and over-using all of the farmland. The topsoil was all running into our rivers and off into the ocean. And it reached a sort of crisis point in the 1920s and early ‘30s.”

FDR had watched the forests disappear and soil erode near his home in Hyde Park, New York. Putting men to work correcting those problems made sense to him.

“FDR was very aware of that. He started a sort of mini-Civilian Conservation Corps in New York state when he was Governor and then when he went to the White House he came up with the Civilian Conservation Corps.”

FDR: “We are planning within a few days to ask the Congress for legislation to enable the government to take on public works, thus stimulating directly and indirectly the employment of many others in well-considered projects.”

But this was new for government. At that time, helping the poor was something for charity, not government.

Harley Jolley is one of four CCC veterans who tell their stories in the documentary.

He says hiring unemployed young men to work in the Civilian Conservation Corps was new to politicians. But they saw it for the practical politics it was.

“And because all those politicians were well aware that they had young men in their hometown, in their home state that could vote for them next time around, ‘Yeah, yeah, we’ll go with you.’ And very quickly it came to pass.”

FDR’s Civilian Conservation Corps was the first, but several work programs followed.

The CCC worked on soil conservation projects, built three-thousand state parks and replanted forests. The men in the CCC planted three-billion trees – that’s estimated to be half of the trees ever planted by humans in the U.S.

This revolutionary idea got off the ground quickly. Camps were set up in every state. Men worked under military officers. The Civilian Conservation Corps members were required to send most of their pay back home.

Sometimes nearby towns welcomed the young men. CCC veteran Vincente Ximenes says, other times, people were wary of Roosevelt’s army of workers.

“And there were some farmers who didn’t like FDR and what he did. He was called a Communist, a Socialist, any name you could find. So, therefore, the CCC-ers also, of course, were no good as far as they were concerned.”

And it wasn’t just farmers.

The documentary’s director, Robert Stone says, in the beginning, President Roosevelt faced a lot of opposition to his government ‘green jobs’ program.

“Well, there were concerns very similar to what you have today with concerns about deficit spending.”

“The national debt today is 30-billion as compared to 19-billions under Hoover. And God knows Hoover was bad enough.”

“So that was on the right. And on the left there were concerns about paying these people a dollar-a-day. The unions were upset about it. But the success of it was such that it really quelled most any opposition.”

The Civilian Conservation Corps documentary, like the other documentaries in the 1930s American Experience series, looks at the connections between environmental damage and economic collapse in a way that still resonates today.

CO2 Helps Trees Grow Faster

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.
