As cities cover more and more surface with pavement and buildings,
it’s taking a toll on the environment. Heavy rains flood off the
impervious surfaces and overload drains and creeks. Some cities are
trying new methods to control the problem. As Tracy Samilton
reports, Ann Arbor, Michigan is asking its residents to play a role by
catching their home’s rainwater in rain barrels:



Miller’s Creek in Ann Arbor is not a pretty creek. Part of it runs
alongside a congested four-lane road in one of the most developed
areas of the city. Since there’s almost no place left for rain to seep
slowly in the ground, it pours off the road and parking lots and
rooftops right into the creek:


“What you can see is all the roots that are exposed and very high
banks…”


Laura Rubin is head of the Huron River Watershed Council. Miller’s
Creek is part of the watershed. She says rain storms carry pollutants
and sediment into the creek, and sweep away animal and plant
species that might otherwise live here:


“This is not a healthy creek we call this impaired when they get flows
they’re so strong that they’re tearing away the banks.”


Rubin would like Miller’s Creek to be vibrant with life again one day.
But a lot of changes will have to happen first. She says nearby
businesses will have to build wetlands to retain their storm water.
The city will have to repave the roads to allow more drainage. And in
such a heavily populated area, residents will have to do something
too. Rubin says the first step is teaching people that a single point
source of pollution like a big factory is no longer the biggest threat to
water in their neighborhood:


“Now the main source of pollution is non-point pollution and that’s
us.”


Rubin says rain barrels could play a significant role in healing Miller’s
Creek. Rain barrels are just like they sound: big barrels that collect
water from a home’s rain gutters, to be dispersed later onto lawns or
gardens. One rain barrel can retain up to thirty percent of storm
water falling on a house. Under a dark grey sky that bodes rain,
Dave Aikins shows off his:


“It’s a big, uh, green trash can-like object…aesthetically, uh, I’m not
prepared to defend it.”


Aikins owns a medium-size house in downtown Ann Arbor. Now, with
a rain barrel installed on one side, he’ll catch half the rain that falls on
the house. He uses it to water his garden, but says someday he
might rig it so he can use the water for his laundry machine. A
neighbor kiddy-corner from him has installed one too, and they’ve
had neighborly arguments about proper installation and usage. He
likes how the rain barrel makes him feel.


“Living in an urban area, there’s no direct impact on you whether it
rains or not and this puts you back connected to natural environment,
so you start to care about whether you get your rain today.”

Aikins and other city residents have more than environmental
reasons to install rain barrels. The city water department is using a
carrot and stick approach to encourage their adoption. Installing a
rain barrel gets you a modest discount on the City of Ann Arbor’s new
storm water rates. Tom McMurtry is head of the new program:


“Under the old system, we charged one flat rate for every single
household whether you were an 800-square foot home in the city or a
5,000 square-foot mega-mansion.”


Now, the city will charge four different rates depending on the amount
of impervious pavement and size of the roof on the house. The
highest rate is three times more than the former flat rate, to better
reflect a big home’s impact on the city’s drains and creeks.
McMurtrie says about (blank) people have installed a rain barrel and
applied for the credit. He’d like to see at least 3,000 rain barrels
installed throughout the city. He doesn’t know how long it will take
to accomplish that:


“But every little bit helps.”


It’s an experiment in progress to see if having lots of rain barrels
around Miller’s Creek will help restore it. According to Laura Rubin
of the Huron River Watershed Council, it took about fifty years to
damage the creek this badly. It could take another fifty to bring it
back to health.

Ethanol Part 2: Widening the Dead Zone?

  • Farmer Laura Krouse says the ethanol boom has been great for corn farmers, who she says are finally getting a fair price for their corn. But she says she's worried that there's not enough being done fast enough to reduce the dead zone in the Gulf of Mexico. (Photo by Rebecca Williams)

Scientists are predicting the Dead Zone in the Gulf of Mexico will reach its largest size ever this summer. Fish and shrimp can’t survive in the Dead Zone. It’s believed to be mainly caused by fertilizer washed from farm fields across the nation.

Scientists are predicting the dead zone in the Gulf of Mexico will reach its largest size ever this summer. Fish and shrimp can’t survive in the dead zone. It’s believed to be mainly caused by fertilizer washed from farm fields across the nation. Rebecca Williams reports some scientists say demand for ethanol made from corn could make the dead zone even bigger:


(Sound of tractor raking hay)


“It’s the perfect Iowa day, you know?”


Laura Krouse is tearing apart a bale of hay to mulch her tomatoes.
She’s a thousand miles from the Gulf of Mexico. But she points out,
what happens on farms here ends up affecting life way down South:


“This watershed I live in drains 25% of Iowa. And we’re one of the
richest farming states in the nation – of course we have something to
do with it.”


By “it,” Krouse means the dead zone. All or parts of 31 farm states
drain into the Mississippi River, which empties into the Gulf.
Scientists point to nitrogen fertilizer used on farm fields as the main
cause of the dead zone. All that nitrogen causes an enormous algae
bloom. When the algae dies it drops to the ocean floor. Bacteria eat
the algae and they rob the water of oxygen.


This summer, the dead zone’s predicted to reach a record size. It could get as big as the state of New Jersey.


Laura Krouse has been trying to cut back her own role in the dead zone.
Five years ago, she added something to her farm that’s rare around here.
Krouse cut some of the tile lines that drain water from her farm, and
replaced part of her farmland with a prairie wetland. She says that
made her neighbors nervous:


“We just don’t see people taking land out of production in Iowa very
frequently.”


Wetlands like this one remove nitrogen from the water that flows from
farm fields.


It’s one of the things a government task force on the dead zone
recommended to cut nitrogen loading into the Gulf.


But instead of a big push to restore wetlands, the economic landscape
is changing in the other direction. Demand for ethanol has led to
historically high corn prices. And that’s encouraging farmers to grow
more corn. A USDA report says farmers have planted 14 million more
acres of corn this year than last year. It’s the most corn planted in
the U.S. in more than 50 years.


Laura Krouse says this is not good for the Gulf of Mexico:


“I’m concerned about all the extra corn because it requires nitrogen to
produce that corn and no matter how careful we are and no matter how
expensive it is which causes us to be more and more careful with
application, nitrogen as a molecule just wants to get away. It is
leaky.”


When it rains, nitrogen runs quickly from farm fields and gets into
creeks and rivers. The federal government’s task force on the dead zone has been trying to
tackle all this.


Don Scavia led a group of scientists advising the task force under the
Clinton Administration. The Bush Administration convened a new science
panel to review the original science panel’s work. Don Scavia says
since then, there’s been very little progress in shrinking the dead
zone, or what scientists call an area of hypoxia:


“In fact what we’ve seen in the last year is just the opposite with
this push towards corn-based ethanol production. Even acres that were
set aside into conservation are coming back out into production, into
corn, and the increased nitrogen load to the Gulf this year and the projected record
hypoxia is probably caused by this increased corn production.”


Scavia says if the dead zone keeps increasing, the Gulf shrimping
industry could collapse.


Ironically, the new science panel appointed by the Bush White House is
calling for even bigger cuts in nitrogen than the first panel appointed
by the Clinton Administration. They want to reduce nitrogen from farm
fields and other sources by 40 to 45 percent.


Don Parrish is with the American Farm Bureau. He says those reductions
are too much:


“Those are going to be really difficult and they could cause
significant economic dislocation at a time when I think we need to be
thinking about the products that agriculture produces, and those are
important.”


There’s no question corn for ethanol is at the top of that list right
now. Ethanol’s popular. It’s making farmers richer. It’s making the
chemical companies that supply nitrogen richer. The government task
force has to figure out how to cut back on all the nitrogen that’s
needed to grow all the corn… that’s needed for billions of gallons of
ethanol.

States Struggle to Control Ash Borer

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams reports cities and states are struggling to find money to keep the beetle from spreading:

A tiny green beetle is killing millions of ash trees. And so far nobody’s
found a way to stop it in its tracks. The GLRC’s Rebecca Williams
reports cities and states are struggling to find money to keep the beetle
from spreading:


Once emerald ash borers chew their way into your ash trees, there’s
pretty much only one thing you can do.


(Sound of chainsaw and tree cracking and falling)


Crews here have been sawing down and chipping up trees six days a
week. In some places, crews are cutting down both dead and live trees.
Dead trees are a safety hazard. Cutting live trees near infested areas can
help contain the beetles.


The emerald ash borer is native to China. Scientists think it got in on
wood packing crates more than ten years ago. The emerald ash borer eats
through the living part of the tree just underneath the bark. The beetles
cut off the tree’s water and food supply… so it starves to death. 15
million ash trees are dead or dying in Michigan. Hundreds of thousands
are dying in Ohio, Indiana and Ontario, and it could spread to other states
soon.


Some cities have been hit really hard. For example, some of the trees in
Ann Arbor, Michigan have been dead for a couple of years. Kay
Sichenader is the city’s forester. She says she’s worried about limbs
breaking off trees, or bark falling off in 80 pound chunks.


“There’s some terrifically bad ones out there. Nothing will make me
happier than when those trees are down, I gotta tell you.”


This isn’t the first time cities have lost big shade trees. Dutch elm
disease almost wiped out American elms in the 1960’s and 70’s. It’s a
little ironic: people planted ash trees to replace the elms because they
thought ash trees were invincible.


That love of ash trees means cities are losing 20 or 30 percent of their
trees, and they’re spending millions of dollars to take trees out.


Forester Kay Sichenader says her city normally takes out a thousand old
trees a year. Now, she’s got ten times as many trees to cut down.


“If I never bumped it up, and we just remained with our thousand a year,
we would never change because it would take me ten years to get the ash
out. In the meantime I’d have 10,000 more dead trees to deal with. It’s
sobering.”


Sichenader says the city’s trying to get the dead ash trees out as fast as
they can. She’s contracted five extra crews to saw down trees. She
hopes they’ll be done by the end of the year, but it might be longer.


Many homeowners are getting impatient. They’re worried about big
branches falling on their cars or homes. Or worse, falling on their kids.


Laura Lee Hayes lives in a cul-de-sac with four infested ash trees. She
points out a big branch on her neighbor’s dead tree.


“This whole piece is just laying here, ready to pull off, and there are
small children that play in this yard. That’s why I look to my city to get
over here and get these trees down. There’s a real frightening aspect to
that.”


Hayes says she tried to pay to take the trees down herself, but she found
out it would’ve cost more than a thousand dollars.


In Indiana, homeowners now have to spend their own money to get rid of
dead trees in their yards. State officials say they can’t afford to keep
cutting down live ash trees to slow the infestation. The state won’t be
giving money to help cities cut down dead trees either. That could mean
the emerald ash borer will spread unchecked.


At first, the federal government sent states several million dollars to fight
the beetle, but now the money’s just trickling in. In 2004, Michigan
Governor Jennifer Granholm asked President Bush to declare the state a
federal disaster area. That request was denied. Recently, officials in
Ohio and Michigan said they’ll have to cut back on containing new
infestations.


These trends worry scientists.


Deb McCullough is a forest entomologist at Michigan State University.
She says states barely have enough money to monitor how far the beetle’s
spreading, and she says a lot more money’s needed for ad campaigns to
tell people to stop moving firewood. The beetle spreads fastest when
campers or hunters move infested wood.


“You have to look down the road, and either you spend millions of
dollars today to try to contain emerald ash borer or we’re going to be
looking at losses in the tens of billions of dollars in the future, and it’s not
too distant of a future.”


McCullough says if more funding doesn’t come in states might need to
have timber sales to take ash out before the beetle kills it. And cities will
still be paying millions of dollars to take out dead trees. That means
people who live in those cities might see cuts in other programs or have
to pay higher taxes.


Deb McCullough says the economic impacts are serious… but the
environmental impacts could be even worse. She says it’s hard to know
how wildlife might be affected if we continue to lose millions of ash
trees.

Ten Threats: Coaster Brook Trout

  • A close up look at a Coaster Brook trout. (Courtesy of the Wisconsin Department of Natural Resources)

A lot of native fish have been hurt by pollution, invasive species and changes we’ve
made on the lake, but one fish stands out. For anglers, the Coaster Brook trout might have
been the greatest Great Lakes fish. It was abundant, fun to catch and lived in the cleanest
water, but throughout the 20th century, its populations declined just as the health of the
lakes did. Now, slowly, a diverse group of people is trying to save the fish in an effort
that could improve the Great Lakes too. The Great Lakes Radio Consortium’s Chris
McCarus reports:

We’re continuing our look at Ten Threats to the Great Lakes. Lester Graham is the
series guide. He says one of the threats is a disappearing species.


A lot of native fish have been hurt by pollution, invasive species and changes we’ve
made on the lake, but one fish stands out. For anglers, the coaster brook trout might have
been the greatest Great Lakes fish. It was abundant, fun to catch and lived in the cleanest
water, but throughout the 20th century, its populations declined just as the health of the
lakes did. Now, slowly, a diverse group of people is trying to save the fish in an effort
that could improve the Great Lakes too. The Great Lakes Radio Consortium’s Chris
McCarus reports:


(Sound of river waterfall)


Hundreds of feet above Lake Superior, the Salmon Trout River flows fast and falls hard
onto a rocky bottom below. Much of the river lies within a large tract of private woods
and hills. It’s been untouched for about a century.


Peter Dykema and his family are part owners of the land. He speaks with affection about
fishing for coaster brook trout here as a kid.


“Well as you can tell it’s a beautiful river and there’s nothing a 14 year old boy would
rather do than get his feet cold and wet and throw flies into trees. So, I did it every
chance I had.”


Dykema is nostalgic because those days are long gone for almost everybody. He’s part
of a group of activists trying to restore the coaster brook population.


Coaster brook trout have sparkling colors. They’re even more colorful than Rainbow
trout, and they grow a lot bigger. They can reach 2 feet and 4 pounds. These indigenous
fish used to live in 200 streams around Lake Superior. People came from all around the
nation to fish for them. Presidents Roosevelt and McKinley came to Michigan to catch
them, and they were caught by the boatload.


Over fishing was one of the biggest reasons why they were nearly wiped out. Their
habitat was damaged from mining and road building. Silt filled in the rock bottom where
they like to lay their eggs. That also hurt the fish.


Logging damaged the coaster brook’s habitat. Scott Libants is a fish and wildlife
researcher at Michigan State University. He says loggers dammed up streams to flood
them. Then they packed them with logs. When they had enough, they broke the streams
back open so the logs would float down to the lake to be sold.


“You knock the dam out and send all the trees down. You scour the watershed. It’s like
flushing a toilet.”


The fish haven’t recovered since. They just couldn’t take the abuse.


The Salmon Trout River still has them because the private landowners banned fishing
and didn’t alter the land. It’s one of only a handful of streams in the U.S. and Canada
that still has the coaster brook trout.


(Sound of people walking in the woods)


Downstream on the way to Lake Superior, Peter Dykema and state environmental
officials walk to the spot where they have equipment that counts the numbers of coaster
brooks going up river to lay their eggs. Dykema says they counted more than 80 fish last
season. The population seems to be slowly increasing here, but the stream still isn’t
perfect. There’s too much sand and not enough gravel for laying eggs.


“Most of the sediment problem we are looking at is a creature of the last 40 or 50 years.
So if we can stop the input, I’m hoping that the river will be able to cleanse itself.


The sediment Dykema is talking about comes from the points where roads cross the river.
People and cars jar soil loose and it fills up the riverbed. This is the fish’s current
challenge. Coaster brook trout are sensitive and susceptible to pollution. Conservation
officials use brook trout as indicators of high water quality. Coaster brooks will die if
they don’t have nearly perfect conditions.


(Sound of Lake superior waves lapping on rocks.)


Few anglers alive today have seen coaster brook trout, but if they could this would be the
place. It’s where the Salmon Trout River meets Lake Superior. For a diverse group of
conservationists, this place symbolizes what people did to the land and water of the
region.


Laura Hewitt is visiting from Trout Unlimited in Wisconsin.


“This is a fish that presidents came to fish for, that Hemingway wrote about. It’s
something that captures the imagination, it touches the soul. It’s a fish that we care
very much about and think it can be sort of a rallying point for action in the basin.”


Those working to preserve the last few hundred coaster brook trout say we should feel
lucky that they’re not all gone. They say now’s the time to keep what’s left, build it up,
and use the eggs from this small population to start the fish in other streams of Lake
Superior. Then perhaps within our lifetime, our children can enjoy the fish that our great
grandfathers did, and in doing that, they’ll know the water’s clean.
