When somebody says a natural area, does 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.

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.

“You lose millions of years of evolution of these thousands of species that may be important to the planet, so why not have some places where we can take care of them?”

Packard says some natural areas are so unhealthy, that for now, we need to protect some parts of nature from others.

And if you don’t buy that – you don’t buy restoration.

Growing a Garden on Your Garage

When most people put a new roof on
their home they usually use standard asphalt
or tile roofing. But other people are going
for something more natural. They’re planting
grass and flowers on their houses. Joyce
Kryszak talked with one builder in
Western New York who planted a green roof on
his garage to show his neighbors how it works:

About 90% of all residential roofs are made out of manufactured
asphalt.

But builder David Lanfear knows that nothing tops mother nature.
He makes roofs out of gardens.

Lanfear recently ‘installed’ one on his own garage roof, so his
neighbors could see the benefits. There are beautiful flowering
plants visible over the edge of the flat roof. Lanfear says they’ve got
the whole birds and bees thing going on.

“We’ve noticed a big increase in insects, butterflies, birds all
sorts of new birds that I haven’t ever seen. They’re up there
eating something. Bugs? But its kind of nice to sit on the deck
and watch this nature in the city thing,” said Lanfear.

But the living roof isn’t a novelty. Lanfear says the roofs are more
eco-friendly. He says a living roof provides a whole cascade of
environmental benefits.

“Especially in a downtown when you get a hard rainfall the water
washes off all at once. There’s nothing to absorb it. If you had
a roof like this it absorbs the water and let’s it off slowly. So, it
not only slows the runoff, it cools the water and it starts to filter
the water. It filters some of the atmospheric crud out.
Otherwise, you get super heated water rushing off into the storm
sewer, and then out into the river or the lake and effecting the
environment there,” said Lanfear.

Once his neighbors understood the concept, they stopped thinking
Lanfear was crazy. A few even offered to give him a hand planting
his roof.

First the roof was reinforced with used lumber. Next are the
waterproof barriers – a rubber membrane, a root barrier made out of
old billboards and some old carpeting. Finally, recycled, crushed
concrete is shoveled on to be used as soil for the plants to grow in.

It’s all sustainable. And the native plants require very little water or
maintenance.

Neighbor Deborah Bach loves to garden. So, she was happy to
pitch in. Bach says the concrete soil needs to be doctored to enrich
it. But they have a reuse idea for that too.

“My son works at Starbucks and they give out free grounds for
gardens. So, we’re going to try doing that to try to balance this
out. You know, using recycled materials and things that have
already been used,” said Bach.

Another neighbor stopped by to help. Alex Sowyrda is a high school
technology teacher who’s interested in the science of green roofs.
He plans to share what he learns with his students.

“I try to bring it into my curriculum at school and, hopefully, the
kids graduating high school now take this knowledge with them
and are able to make responsible choices in the way they build
and the way they design in the future,” said Sowyrda.

The living roof builder David Lanfear says it’s a concept that can grow
on anyone. Even people who grew up with more traditional roofs. He
says to start small – with a garage roof – or maybe even smaller.

“We all have little expanses of roof in front of windows. And in
the summer you might notice that when the window is open the
hot air blows in, a lot of that heat comes from that little bit of
roof. If we could just put sections one square yard of living roof
outside of our windows on the porch roof, that would make a
drastic difference in cooling our house – simple,” said Lanfear.

And pretty cheap. Lanfear says the cost of materials is about the
same as an asphalt roof. But he says there’s savings in the long run
because the green roof can last three times as long.

And he says it’s a whole lot nicer to look at.

Growing Grass for Ethanol

The US is in the middle of an
ethanol revolution, or at least it’s
supposed to be. Scientists want to
develop ethanol that doesn’t use corn
– so food prices won’t go up. They’ve
found a tall grass called miscanthus that
can produce loads of ethanol – but they
haven’t perfected it yet. Shawn Allee reports some are trying to grow
miscanthus before the ethanol revolution
arrives:

You won’t find much miscanthus near Decatur, Illinois.

Nope. Corn is crop number one.

But all this corn-growing has a downside.

Agronomist Stephen John offers to show it to me.

Shawn Allee: “Where are we?”

Stephan John: “Well, we’re near the upper end of Lake Decatur, looking across at
the city’s dredge. Right now that dredge that is sucking up sediment from the lake
bottom.”

John says corn can leave ground bare, and rain washes dirt and fertilizer pollution into
this lake.

“Some of that nitrogen gets into streams and ditches into Lake Decatur, which had
to develop a facility to protect drinking water.”

John wants farmers to protect soil from erosion and use less fertilizer.

One option is to grow grasses that hold soil and use less nitrogen. One candidate is that
miscanthus grass the ethanol industry’s interested in.

Problem is, no one buys miscanthus yet.

“So, the trick is how do you make it economically viable to get those grasses onto the
land, how do you make that attractive?”

John says people are working on that problem.

Farmer Eric Rund stands near a patch of miscanthus grass. He’s a pretty tall guy, but the
grass is even taller.

Shawn Allee: “I’m putting my hand through here.”

Eric Rund: “It’s like a jungle in there, it’s like bamboo growth or something.”

Rund says corn farmers get kinda freaked out by miscanthus. It doesn’t grow from seed,
and unlike corn, it takes years to produce.

He says farmers need to experiment with it.

“And if we do that now, when ethanol production comes along, we will then have a
reliable source of biomass for the ethanol plant.”

Rund says some farmers would grow miscanthus just to protect water and soil. But to
make it mainstream, it’s gotta be profitable.

“That’s the key. No farmer’s going to plant much of it unless there’s a market for it
and there’s no market for it unless there’s a steady supply of it, so the two are going
to have to grow together.”

But what if that takes a while for the ethanol industry to come knocking? Who would use
Rund’s miscanthus?

I meet a guy who’s working on a solution.

Gary Letterly: “What would you like to do, where would you like to start?”

Shawn Allee: “I want to see your furnace.”

I’m with Gary Letterly. He works with the University of Illinois.

He says in corn country, some people heat their homes with corn pellets.
That gave him an idea on how to heat his office.

“And what you see here, it was a corn furnace, and we thought it would be just
great if we could use that furnace and burn grass pellets.

Right next to the modified furnace, there’s a plastic hopper full of miscanthus pellets.

They look like rabbit or hamster food, and they smell like grass.

“Look at high energy costs. This was very competitive with natural gas, and the very
nice thing is being able to keep this value very close to home. The grass was
produced within fifteen miles, the furnaces were produced within five miles, and the
grass was processed into a pellet within 30 miles.”

Letterly says miscanthus offers enough local economic and environmental benefits that
people should look into it now.

It already has potential to be a kind of super-star plant, with or without help from an
ethanol industry may never come.

Life After a Forest Fire

  • Biologist find signs of regeneration shortly after a forest fire. (Photo courtesy of Stephanie Hemphill)

Forest fires capture a lot of attention and concern. Loggers worry about lost resources. People who hike and camp in the forest worry they’ll see nothing but ugly, blackened vistas for years to come. But a big fire this summer in the northwoods gives people a chance to see just how fast the forest can recover. Even as the fire still burns, foresters see signs of life.

Forest fires capture a lot of attention and concern. Loggers worry about lost resources.
People who hike and camp in the forest worry they’ll see nothing but ugly, blackened vistas for years
to come. But a big fire this summer in the northwoods gives people a chance to see just
how fast the forest can recover. Even as the fire still burns, foresters see signs of life.
The GLRC’s Stephanie Hemphill reports:


The Cavity Lake fire started in mid-July this summer. It turned out to be the fire people have been
worrying about for seven years. In 1999, huge straight-line winds knocked down millions
of trees. They toppled into an impassable tangle of drying fuel in and near the Boundary
Waters Canoe Area Wilderness in northeastern Minnesota. Locals call it “the
blowdown.”


The Cavity Lake fire gobbled up the blown-down trees. It roared across lakes,
threatening homes and resorts.


(Sound of boat motor)


Two forest service workers hop in a small boat to document the fire and its aftermath. In
places, the fire seems to have consumed everything, down to the soil, but these two are
looking for life.


Black, powdery ash covers the ground. Burned snags, limbless trees the color of
charcoal, stand against the sky. But even here, biologist Lissa Grover can find signs of
life.


“If you look around, you can see the 20-foot tall trees that took off after the blowdown,
and a lot of them still have cones on the top, and those cones are open now, and the seeds
will fall from them into the bare soil and germinate.”


In fact, some seeds, such as Jack Pine, wait for fire to open:


“There’s a seed bank in the soil, just waiting for a disturbance like this. There’s one plant
called Bicknell’s geranium that sprouts after fire, produces flowers the second year, sets
seed. Those seeds will stay in the soil until the next fire, even if it’s 200 years from now.”


And some plants aren’t waiting for the next generation. Grasses are already pushing
green shoots through the blackened dirt.


(Sound of motor)


Our next stop is a big island. After the 1999 blowdown in northeastern Minnesota, the
Forest Service purposely burned some areas near homes and resorts. The idea was to
reduce the amount of fuel available for wildfires. Crews set this island on fire four years
ago.


Wilderness ranger Tim McKenzie says that intentional burn saved the island, and the
resorts, from the Cavity Lake fire:


“It was traveling pretty good distances and spotting on these islands. As soon as it hit
here it just lay down.”


The blowdown fuel was already burned, and the young trees were too small and green to
keep the fire going.


Animals here are also adapted to fires. Bears, wolves and moose can walk away from a
fire. Birds can fly away or take refuge in the water.


Grover does worry about the young eagles, still in their nests and unable to fly.


“The trees are still there, the nest is still there, the adult eagles are still here, but it’s
unlikely that the juveniles in the nest survived the fire.”


But a few minutes later, we hear a sound that gladdens Grover’s heart: a young eagle
screaming for food.


(Sound of eagle)


At least one young eagle survived the Cavity Lake fire.


This land has been swept repeatedly by fires. They start, grow, move, and burn out in a
patchwork pattern. A fire last year burned until it ran into an area that had burned thirty
years ago. And here, in a thirty-year-old burn, is a picture-perfect Boundary Waters
portage.


(Sound of walking)


Young balsams scent the air with their clean, northwoods smell. Young birches lean
across the path. The moss is soft underfoot. The air is moist, and the mosquitoes are
buzzing.


Tim McKenzie fought that fire, thirty years ago. He says whenever fire burns, it’s nature
at work:


“People are used to seeing a snapshot in time. But the landscape that they’re used to
seeing became that landscape because of this process.”


And canoe outfitters here are busy planning routes that will show that landscape changing.

Low-Cost Sewer Solutions

Many communities throughout the country are rebuilding their sewer
systems to comply with federal pollution regulations. Nationwide, the
work is costing taxpayers billions of dollars. But in some communities, a
concept called “low-impact” design is making the projects cheaper and
better for the environment. The GLRC’s Erin Toner reports:


Dump trucks, black plastic pipes and huge piles of dirt line the streets of
this suburban neighborhood. It was built on very flat land and water
doesn’t run off. It used to be covered in ponds of wetlands. Now, that’s
causing big problems for people who live here. Their basements are
nearly always flooded and after it rains, they have pools of water in their
backyards for weeks, or months. Many run sump pumps all day and all
night.


Jesse Ramos lives in a white ranch house in the neighborhood.


“Actually, this past couple of months I’ve had a lot of problems with
water in my basement. I’ve actually already been through one sump
pump and I’ve went out and purchased another, just so I could keep up
with that. Right now that it hasn’t rained I’m okay. So, I’m a little
nervous when it starts to rain.”


Fixing these problems the traditional way – with concrete pipes, curbs
and gutters – would have cost 20 million dollars, and it would have
sent polluted storm water straight to the river, but Pat Lindemann wanted
to do the project differently. He wanted to save people money and clean
up the environment. Lindemann often sounds more like the head of a big
environmental group, than what he actually is – the county drain
commissioner for this neighborhood near Lansing, Michigan.


“A lot of people argue that if I own the wetland, I should be able to
destroy it, but you shouldn’t because… what you do on your property
affects the river, every time you over fertilize your lawn, every time you
do not pick up your domestic pet waste… this country has such a vast
amount of beautiful resources, and for 150 years, we’ve done everything
that we could to beat up on it.”


In Jesse Ramos’ neighborhood, Lindemann’s using low-impact design to
rebuild the drain system. It’s costing half as much as concrete curbs and
gutters.


“In the case of low-impact design, we force the water to go through soils,
to interact with plant roots, to stay on the land slightly longer and
become treated before it leaves to make its way to the river.”


The main way that happens is through rain gardens, one of the main
features of low-impact design. They’re bowl-shaped gardens planted
with native flowers and grasses. Native plants have long roots that draw
water deep into the ground and provide a natural filter for pollution.
Rain water collects in the gardens and becomes cleaner before eventually
reaching the pipe that takes it to the river.


Lindemann’s installing more than seven acres of gardens in the
neighborhood. He says people will have a few hours of standing water in
rain gardens, instead of weeks of water in their backyards.


Jesse Ramos is hearing this good news for the first time today…


“…now you’ll be flooded for about an hour and a half…an hour and a
half…that’s wonderful…and it’s pretty flowers…”


There’s another low-impact design project across town. Drainage
problems were causing backups in peoples’ homes. So, Drain
Commissioner Pat Lindemann built 20 acres of wetlands – right in the
middle of the city.


“It dawned on me, why take the water anywhere, why not just keep it. If
I can find a place to store it, put it and manipulate it, and not take it
anywhere, than I could manage it.”


This site is technically a series of retention ponds, but it’s really more
like a park. A paved walking path weaves around ponds and trees and
over bridges. It’s a place you’d bring school kids to learn about frogs
and birds and about being good to the environment.


This low-impact design project, like the one in Jesse Ramos’
neighborhood, was about half the cost of installing new concrete pipes
from the neighborhood to the river.


Low-impact design projects are happening all over – in Chicago and
Seattle, to more rural communities, and they’re likely to become more
common as cities consider how to cut non-point source pollution – the
leading cause of poor water quality. Non-point source pollution is a lot
of things – the fertilizer we use on our lawns or bacteria from animal
waste.


Pat Lindemann says his philosophy is that our dirty rivers will recover if
we start developing the land or rebuilding it the right way – one rain
garden or wetland at a time.

Cities throughout the country are spending millions of dollars to rebuild
aging sewer systems. But in some communities, a trend called “low-
impact design” is making these projects more affordable for taxpayers,
and better for nature. The GLRC’s Erin Toner reports:


Low-impact design focuses on restoring natural ways to manage storm
water, instead of building sewer systems that send polluted water straight
to rivers and streams.


Rain gardens are one feature of low-impact design. They’re bowl-
shaped gardens planted with native flowers and grasses. Water collects
in the gardens and becomes cleaner as it seeps through the soil.


Pat Lindemann is a county drain commissioner in Michigan. He’s using
low-impact design to deal with flooding problems, and to clean up local
waterways.


“If we can take neighborhood by neighborhood, one rain garden at a
time, one constructed wetland at a time, manage our storm water, polish
it, clean it, discharge it at a lower rate, our rivers will start to recover.”


Lindemann says he’s done two low-impact design projects at half the
cost of rebuilding drainage systems with concrete pipes, curbs and
gutters.

Bug-Eating Birds Avoid Development

Researchers have found that building housing along lakeshores affects the kinds of birds drawn to the area. The Great Lakes Radio Consortium’s Lester Graham reports:

Transcript

Researchers have found that building housing along lakeshores affects the kinds
of birds drawn to the area. The Great Lakes Radio Consortium’s Lester Graham reports:


Researchers have been looking at the differences between populations of birds along a lakeshore where houses have been built and where they’ve not. Alec Lindsay is a University of Michigan doctoral student who’s been working with the Wisconsin Department of Natural Resources, studying the birds…


“What we found is that the birds that feed on insects were found less frequently on lakes
that had significant shoreline development than lakes that were undeveloped. And on the other hand, birds that feed on seeds which are not normally associated with these sorts of habitats were found more frequently on developed lakes than undeveloped lakes.”


So, lakeshore housing developments might be discouraging the kinds of birds that eat mosquitoes and keep down other insect pests. Conservation officials suggest homeowners should plant more native shrubs and grasses to encourage the bug-eating birds to stay.
