The word “suburbia” conjures up sprawling developments, huge lawns and
long commutes. It’s not the most eco-friendly arrangement. Jan
Spencer lives in the suburbs and he wants to change their reputation. His
version of home improvement is making his quarter-acre property as
energy-independent as possible. As Ann
Dornfeld reports, Spencer calls the process “suburban renewal:”


When you get to Benjamin Street, you don’t need to look at house
numbers to find Jan Spencer’s place. His is the one with a jungle of berry
vines instead of a yard. Oh, and if you drove here, you’ll need to park on
the street:


“I removed my driveway early on when I moved here because I didn’t
need space to park five cars. So I took my driveway out and I kept a lot of
my driveway to make landscaping features!”


Spencer stacked pieces of the broken driveway to line two ponds. He
collects rainwater in a huge tank out back and fills the ponds with it:


“But that’s a habitat! There’s pollywogs in there, there’s fish in there, there’s
little water skimmers.”


This is more than just funky, utopian landscaping. It’s permaculture. That’s
the practice of using natural resources found on-site to fulfill as many
needs as possible. Permaculture takes the trend of “buying local” up a
notch. You don’t just eat organic asparagus grown 20 miles away, or heat
your home with wind energy from across the state. You produce those
things yourself, at home.


Even in a vinyl-sided tract house in the suburbs, Spencer says, there are still
plenty of natural resources available:


“Soil… sunshine… and rainwater.”


And, he says, multi-purposing can make the most of the space available.
For instance, Spencer converted his carport into living quarters for
roommates. That creates a higher-density living arrangement. Next, he
plans to grow watermelon or squash on the roof.


“When you really start looking around a location with a set of
permaculture eyes, ‘How can I use this space most effectively?’ even
familiar places take on a really different kind of an appearance.”


Spencer knows not many people are willing to tear out their driveways to
have more room for raspberries, but he says there are plenty of simple
ways to harness a suburban home’s energy potential. Solar panels on his
roof heat his water for the warm half the year. Low-tech systems work, too,
like composting and watering the garden with a can instead of soaking it
with a hose or sprinkler.


To see which of Spencer’s suburban renewal methods might work for the
average family, we go next door to visit the Finneys. Dan is a firefighter.
Eden stays home with their young daughters, Peyton and Madison. The
girls like to raid Spencer’s berry patch. But the Finneys are pretty fond of
their grass lawn. Their minivan and RV are parked in the intact driveway.


Eden says the couple does want to make their home more energy-
efficient, but for different reasons.


“For him, definitely it’s cost. But for me, the environment plays a big part in
it.”


The Finneys already grow fruits, vegetables and herbs in raised beds out
back. And they installed energy-efficient windows:


“It knocked our bill down considerably this last winter. That was a good
thing to do for us.”


Spencer and I wander out to the Finneys’ covered back porch. Spencer
says the Finneys could close it in with removable clear panels to lower
their heating bill even further:


“The solar orientation here is perfect. So part of the year it’d be totally
open like this, and part of the year this place could actually be helping to
heat the house.”


“Huh. Didn’t even think about that!”


Spencer says the trick is to look at under-utilized spaces, like the
boundaries of the Finneys’ property:


“And having some kind of grapes, kiwi fruit, some type of edible vine
growing along the front of that fence.”


“We talked about doin’ that and we will do that. We’re gonna build a trellis
there. I just haven’t got around to it. As you can see, this is the project
house. And we do want to grow some kiwi. And they can grow really fast.”


Spencer’s ideas are going over pretty well, so he decides to go out on a
limb.


“Okay, I’ll just suggest something. What would you think of the idea of
having a 1600-gallon water tank up on blocks there to help water your
garden?”


“No.”


“No.”


“Maybe one behind the shop, and do the same kinda thing back there
where it wouldn’t be in the middle of our yard.”


“Ah, okay, so it’s the idea of where something like that would be.”


“Probably. Yes.”


“Yeah!”


Spencer needs this kind of feedback as he gets ready to take his
suburban renewal philosophy on a speaking tour. He’ll be talking to
longtime permaculture activists as well as more mainstream suburban
residents who just want to make a dent in their utility bills.

a key part in the surgery room:


The Nerites Corporation specializes in bio-degradable, waterproof
tissue adhesives. The concept is familiar if you’ve ever superglued
your fingers together.


The Madison, Wisconsin company is currently developing an adhesive that
could be used in complex heart surgeries, to seal, attach, or re-join
blood vessels. CEO Thomas Mozer says they’ve based their research on
zebra mussels, which attach themselves to surfaces like ship’s hulls
and water intake pipes.


“They adhere to surfaces underwater in the rather messy environment of
the ocean or lakeshore. Where the zebra mussels attach to surfaces.
The kind of environment where synthetic adhesives made by man – prior
to ours coming along – wouldn’t work.”


Mozer predicts it’ll be about three years before the tissue adhesive is
perfected for use in hospitals and clinics.

Ten Threats: Botulism Kills Beach Birds

reports:

Transcript

We’ve been bringing you reports from the series, ‘Ten Threats to the Great Lakes’ which is now looking at the threat to beaches. Our guide through the series is Lester Graham. He reports that scientists are beginning to understand what’s killing thousands of Great Lakes shorebirds. It might be part of a larger problem indirectly caused by humans.


Researchers are beginning to understand what’s killing thousands of
Great Lakes shorebirds. It might be part of a larger problem indirectly
caused by humans. The Great Lakes Radio Consortium’s Lester Graham
reports:


Along parts of Lake Erie, Lake Ontario, and Lake Huron, large numbers
of dead birds and fish are washing up on shore. If they’re left there, the
disease that killed them can be passed on to other wildlife. That’s why
park officials such as Mike Mumau at Presque Isle State Park at Erie,
Pennsylvania ask their staff to watch out for the dead carcasses.


“Our interns do a great job. They’re the eyes of the staff that are out. So,
there’s probably three to four days a week that they’re out on the
beaches, checking to see if they have anything.”


Since 1998, untold numbers of fish and sometimes hundreds of dead
birds a year have washed up on just these eight miles of Lake Erie beach.


Eventually, researchers figured out the problem: type “E” botulism. It
slowly paralyzes the birds until the respiratory system shuts down. Most
of them don’t make it that long. They get so weak they can’t hold their
heads up out of the water and they drown.


(Sounds of walking and shovel)


Leslie Jones and her fellow interns are headed out to an area to pick up
some dead seagulls on the beach.


“When we’re out here doing migratory bird studies, we might see some
and then we pick them up as soon as possible. A lot of times, we get
radioed from different people like lifeguards and they have us come out
and pick them up so that the disease doesn’t spread throughout the rest of
the ecosystem.”


They find five dead birds rotting on the beach. They bury the maggots
because they could carry the botulism toxin and other birds might eat the
maggots. They shovel the bird carcass into a black plastic garbage bag.


“If they’re very fresh, this one, obviously not very fresh, but, if we get a
fresh one, we actually freeze them and they’re sent off to be tested
botulism, but, something like this we’ll just bag up until we can get them
incinerated to get rid of all the disease.”


The fresh carcasses are shipped to the National Wildlife Health Center in
Madison, Wisconsin.


There, Grace McLaughlin is among the researchers who are beginning to
put the puzzle together.

Here’s what they think is happening. The invasive species zebra mussels
and quagga mussels create huge mussel beds that begin a complicated
biological phenomenon. Organic matter collects there, and then decays. It
lowers the oxygen level in the immediate area of the mussel beds. Type
“E” botulism spores occur naturally, but when the oxygen level goes
down, they begin reproducing like crazy. The waste they produce is the
toxin.


“That toxin will accumulate in the organic matter as well as in the water
in the immediate vicinity of the mussel beds. As the mussels do their
filter feeding, they will accumulate the toxin in their tissue. They are not
susceptible to the toxin. However, when the fish start coming down
there and eating the mussels, they become intoxicated, lose their ability
to swim properly and become easy prey for the birds that come in.”


The fish that feeds on the mussels the most is another invasive species,
the round goby. Researchers made the connection when they noticed the
botulism started being a problem shortly after round gobies arrived in big
numbers.


The type “E” botulism toxin has killed tens-of-thousands of birds such as
cormorants, terns, loons, ducks, and seagulls.


Back at Presque Isle State Park, Mike Mumau says it’s terrible to see so
many birds die.


“We just do our best on our end to stop the botulism cycle. When we
can, provide samples, and also, keep it a positive recreational experience
for all our visitors. They don’t want to see birds decomposing and
rotting out on the beaches, so we’re pretty diligent with that.”


Researchers say that’s about the best that can be done. Since ocean-
going vessels brought zebra mussels, quagga mussels, and round gobies
to the Great Lakes, all three of the invasive species have flourished. It
will likely be a long time before we’ll ever begin to understand the full
extent of the damage to the native wildlife of the lakes.

Women Scientists Still Facing Career Barriers

A new report concludes women scientists at universities still face career barriers that most men don’t. The Great Lakes Radio Consortium’s Chuck Quirmbach has the story.


A program developed by the National Science Foundation looks at efforts to advance women in scientific careers. Leaders of the program have just published a paper in Science Magazine that concludes women scientists are making some gains on campus, especially in the biological sciences.


University of Wisconsin – Madison professor Jo Handelsman co-authored the report. She says at some universities thogh, many women still face hostile climates, lack of training opportunities, and unconscious bias. Handelsman says both men and women may hold the same biases.


“So a lot of people have assumed that if there’s a woman on the search committee or a woman making decisions, then there isn’t going to be a prejudice against women, and that simply isn’t true.”


Handelsman says one goal is to make academic hiring and tenure committees aware of the issue, so they can ask themselves if they’re holding all candidates to the same standard.

Development Triples in National Forests

One of the most comprehensive studies of development in and around national forests spells out the size of some potential threats. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

Transcript

One of the most comprehensive studies of development in and around national
forests spells out the size of some potential threats. The Great Lakes Radio
Consortium’s Chuck Quirmbach reports:


The study by the University of Wisconsin-Madison looked at a half century of
government census data on national forests. The results show the number of
housing units within national forest boundaries tripled between the years 1950
and 2000. There’s also been a big increase in development within a 30 mile
radius of the forests.


Researcher Volker Radeloff says development has brought in more invasive
species… and narrowed the wildlife corridors between forests. He says he realizes
many communities want to grow.


“The danger is if it’s not occurring in a consensus driven or planning process then the
decisions will be made for these communities… and what that means is increasing isolation of
these forests and strong environmental effects.”


Radeloff says in the Great Lakes region, much of the development in and around national forests
is from people building second homes or recreational housing.

Some scientists contend that land use by humans has become a top threat to the planet’s ecosystem. The Great Lakes Radio Consortium’s Chuck Quirmbach reports.


People in cities and towns often spend hours debating local land use issues, but a group of scientists says there should also be a focus on the larger topic of widespread conversion of natural landscapes to uses like urban development and agriculture.


Jonathan Foley is a climatologist at the University of Wisconsin – Madison and lead author of a new study published in the journal Science. He says the Midwest sees its share of large land use changes.


“We grow a lot of corn and soybeans and other crops. But we do so, unfortunately, with quite a bit of damage to some of our environment: water quality, leaching of nitrogen and phosphorus into our lakes and groundwater and streams.”


Foley says the Midwest could look at changing farm subsidy programs to help farmers use better environmental practices. Globally, he says six billion people are competing for food, water, and shelter, and their land use decisions are transforming the planet.

There are several groups in the region working to protect and restore the
endangered Karner blue butterfly. Now these efforts could be helped by a
new computer mapping and statistical modeling technique. The Great Lakes
Radio Consortium’s Chuck Quirmbach has more:


Habitat maps for endangered species can be based on broad general
estimates. But some scientists hope a combination of computer
software and data such as soil type and vegetation will lead to
more accurate information on where the Karner Blue butterfly lives.


David Mladenoff is a professor of Forest Ecology at the University of
Wisconsin – Madison. He says having a better idea of the butterfly’s
habitat might save companies money on things like surveying costs.


“In other words, if they say we’re planning on doing work on this utility
right away or potentially harvest this area of forest, is this even
a place we have to be concerned about for the Karner Blue butterfly
occuring?”


The U.S. Fish and Wildlife Service, a state agency, and some power
companies are funding a computer mapping project in Wisconsin.
Scientists say the same technique could be used in other states.

New Study Shows Long Term Effects of Fertilizers

A new study suggests the build-up of phosphorus in lakes may cause problems
for hundreds of years. The Great Lakes Radio Consortium’s Chuck Quirmbach
reports:


Many farmers and other landowners use phosphorus-rich fertilizers on their property, but when the chemical runs off into lakes and streams, it can lead to algae blooms, depletion of oxygen, and fish
kills.


New research says it can take decades or hundreds of years for phosphorus to cycle out of a watershed. University of Wisconsin – Madison Professor Stephen Carpenter did the study. He says the effects won’t be as long-lasting if more phosphorus controls are put in place.


“For example we could develop more buffer strips, restore more wetlands, move point sources away from streams and lakes and maybe even innovate new technologies for keeping phosphorus on the
land.”


Farm groups say many of their members are trying to reduce soil erosion and chemical runoff. Carpenter says that’s true, but he says in some watersheds, much stronger action is needed.

Researchers continue to look for a more energy-efficient alternative to ethanol. A team of Midwest engineers is having some success with turning plants into an additive for diesel fuel. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Researchers at the University of Wisconsin in Madison are taking the carbohydrates found in corn and other plant matter and putting them into what they call a “four-phase reactor.” Out comes a sulphur-free liquid suitable to be an additive in diesel transportation fuel.


Much attention has been paid to processing corn into ethanol, but Wisconsin professor John Dumesic says he and his colleagues have a more energy-efficient system.


“To make ethanol from an energy point of view, it takes one unit to make one unit. If you look at our process, in a very preliminary sense, then for every one unit you put in, you get two units out.”


Dumesic says the carbohydrate-based diesel fuel additive could be ready for consumer use within a few years. His research is published in a recent issue of the journal Science.

If you feel you just cannot live without wild things, you have something in
common with a conservationist who’s still influencing conservation practices almost
sixty years after his death. Scholars say the theories of Aldo Leopold continue to help shape wildlife management and land preservation, especially in the Upper Midwest. The Great
Lakes Radio Consortium’s Chuck Quirmbach reports:


Aldo Leopold is probably best known for writing A Sand
County Almanac. That’s a collection of essays about finding harmony
with nature. His ideas about preservation changed while working for the
Forest
Service in the southwestern U.S. Rick Stel of the Aldo Leopold
Foundation
says one day in the early 1900’s Leopold shot a wolf thought to be a threat
to
cattle. The female had pups with her.


“And he says he got there in time to see the
fierce green fire die in her eyes… and it was at this time he realized
we’re going about this in the wrong way… we really need to look at all
creatures and everything as a community.”


Leopold’s epiphany led to writings that won him national attention. he
eventually moved to Madison, Wisconsin – first to work in forest
research and later at the University of Wisconsin. There, he taught the
nation’s
first course in game management.


In 1935, he bought an abandoned farm in the sandy floodplain of the
Wisconsin River. It became the inspiration for many of the essays in A Sand County
Almanac.


(sound of unlocking door)


Most tours of the site start at an old chicken coop that was the only
building left when Leopold bought the place and is the only structure
now. The shack, as Leopold called it, has no electricity or furnace.


(sound of fire)


On chilly days tour guides light a fire in the fireplace and talk about
the ideas Leopold developed while visiting the shack with his family.
The Leopold Foundation’s Buddy Huffaker says Leopold worried about
becoming disconnected from nature.


“His February essay talks about the two spiritual dangers of
not owning a farm. One is to assume food comes from a grocery store, and the second is that heat comes from a furnace.”


Outside the shack Leopold and his family worked to return the land to its
pre-agricultural state. They planted thousands of pine trees. The also undertook
one of
the first prairie restorations. The Leopold family spent a lot of time
discussing how
people were damaging the environment.


(sound of brushing)


About one hundred yards from the shack Buddy Huffaker brushes off
a plaque that’s set in the ground. at this spot, Leopold sawed apart a
lightning-damaged oak tree that he called the good oak. He wrote
about the experience in a famous essay that Huffaker says is really
about natural history.


“As he and his family saw through the growth rings of the oak, he
goes back in time to see how people have disregarded other natural
elements in the landscape – the decimation of turkeys and other
species that we hunted into extinction locally or entirely.”


But turkeys, sandhill cranes and a few others species have come
back–in part because of Leopold’s conservation ethic. Now his
followers are trying to protect more things.


To spread Leopold’s message some groups have started sponsoring
readings of Aldo Leopold’s A Sand County Almanac. At a library in Lake
Geneva
Wisconsin Jim Celano reads from the essay about the good oak.


“Now our saw bites into the 1920’s the Babbittian
decade when everything grew bigger and better in heedlessness and
arrogance – until 1929 when stock markets crumpled. If the oak heard them
fall, its
wood gives no sign.”


Celano is a former commerical real estate developer who now heads
a land conservancy group. He says he’s trying to convey Leopold’s
ideas to other developers.


“That we’re not here to say no to development… but to ask
they be sensitive to what they’re developing. And when you step on
their parcel, after their development is done, that the first thing you
notice is what they’re preserved and protected.”


(sound of woodpecker and traffic)


But even Aldo Leopold’s famous land around the shack is not immune
from modern threats. As a woodpecker hammers overhead, the noise
from a nearby interstate highway intrudes into the scenery. The
Leopold foundation’s Buddy Huffaker says Aldo Leopold knew the future
would bring new threats to the natural world.


“But I think that’s Leopold’s challenge to us. He
understood progress was going to continue. He just wanted us to
contemplate what we wanted that progress to be. And how far it
should go.”


And with sales of A Sand County Almanac bigger now than when it was
published in 1949, it ‘s a future Aldo Leopold might be helping to
shape.
