Whitetail deer have adapted pretty well to the suburbs.

But… it means a lot of car-deer accidents. It also means deer munching on tulips and shrubs. Some people consider them pests and want to get rid of the deer.

But instead of simply killing them, one city has decided to capture and sterilize a number of does.

Adam Allington reports, the results might point toward the future of urban wildlife management.

It’s a crisp night in Town and Country, Missouri…home to some 10,000 souls…and about 800 deer.

“There goes a deer over there, it’s just to the left of the tree, you can barely see it.”

Joel Porath is a wildlife regional supervisor for the Missouri Department of Conservation. Just like humans, whitetails he says, are right at home in the quiet cul du sacs of suburbia.

“They have all the food resources, they don’t have hunting and they don’t really have predators, so mainly vehicles are what kill them in communities like this.”

Lynn Wright sits on Town and Country’s board of aldermen. Despite the accidents she says most folks like seeing the deer around…kind of reminding them that they don’t live in the city.

“But when you start going from 2 or 3 and seeing 10 or 12 in the backyard you do start getting concerned about that.”

The car accidents were a problem, but Wright says people also complained about damaged trees and landscaping. Still, the town resisted the easiest solution—to just hire sharpshooters to come in and kill all the deer.

Instead, they explored alternative methods…this is sound from a department of conservation video…it shows four deer eating corn in a back yard…just then, a large dropnet is released…sending them into a flailing frenzy until technicians rush in with tranquilizer shots.

The deer are then brought to Steve Timm. Timm is a veterinarian with White Buffalo Incorporated. Its a company that specializes in sterilizing deer.

“We’ve got two does coming in. We’re going to sterilize them by removing ovaries.”

Timm operates out of a small eight by sixteen foot trailer… When the does arrive they’re hoisted on to an operating table and prepped for surgery.

“I’ve located the left ovary here, and so I’ll clamp it, bring it to the surface, use cautery to prevent any bleeding.”

The whole process takes about 20 minutes. The deer are then stapled up, fitted with reflective collars and released.

Timm says the theory is simple—fewer fauns mean less deer eating shrubs and running into cars.

“The early information suggests, that if there are some deer in the environment, especially our sterile does, the other deer have less tendency to move in.”

But not everyone backs the sterilization approach.

Joe Williamson is a retiree who loves to garden. Walking around his yard he points out flowering magnolias, yews, Japanese maples…basically, a kind of all-night deer buffet.

“This is a good example of antler rubs, this is called Staghorn Sumac. The bucks rub their antlers on here and they break them off, you see all these…its just wrecked.”

Williamson says sterilization does nothing to solve the immediate problem of too many deer. It’s also much more expensive. Town and Country paid White Buffalo 150-thousand dollars to sterilize 112 does, and kill another 100.

But, Joel Porath of the Department of Conservation says in the end, the best solution may involve sterilizing some deer…and killing others.

“Could you imagine if we stopped allowing deer hunting in the state? You know we kill around 300,000 dear each year and it doesn’t take very long for the population to jump back up. So, they do need to continue to do something in Town and Country down the road.”

By the end of spring Porath says the department should have enough information to see if sterilization makes sense for other suburban areas.

You might think the flu season is over, but H1N1 flu is still around. Rebecca Williams reports health officials still want you to get vaccinated against the virus:

H1N1 flu peaked in the U-S last October and November.

The Centers for Disease Control and Prevention estimates through the middle of January, 57 million Americans got sick and 12-thousand people died.

Right now, most of the people getting sick with H1N1 are in the Southeastern U-S.

Tom Skinner is with the CDC.

“We wouldn’t be surprised to see activity continue into the spring and early summer. How much activity we may see moving forward into the fall and winter it’s just hard to tell.”

He says anyone who hasn’t gotten the vaccine should. Especially people with the greatest risk of complications from the flu. Those are pregnant women, kids younger than 5 years old and adults older than 65.

This fall, the H1N1 vaccine will be combined with the regular flu shot.

The pesticide DDT almost wiped
out the double-crested cormorant.
Now, the bird is thriving, and it’s
blamed for devouring fish in lakes,
rivers, and fish farms in many parts
of the country. Karen Kelly reports
on the struggle to share resources
with this unpopular bird:

(sound of clanking and birds)

Mike Smith eases a boat into the shallow water just off Little Murphy Island. It’s a tiny patch of sand and trees in the middle of the St. Lawrence River. It straddles the New York border with Canada.

Smith is a wildlife technician with New York’s department of environmental conservation. He specializes in cormorant management. That means he knocks down nests, breaks eggs, and – very occasionally – shoots them.

Before he even jumps off the boat, he starts counting the birds that are poking out of nests in the treetops.

“I see a few. I’m looking at their nests. We tried to have a zero percent successful reproduction rate.”

Smith counts maybe ten nests. They started with 150 or so in the spring.

There are tens of thousands of these birds. They spend their summers in the north. And in the winter, they go south where they raid fish farms.

Biologists estimate each bird eats a pound of fish a day. That can make a dent in the local fish population. The birds also strip trees of their leaves to create nests. And their guano ends up killing the trees’ root systems. That ends up driving out other animals that need vegetation.

Some people feel the birds should be eradicated. One group of anglers was even arrested for killing hundreds of them on Lake Ontario.

There are others, like the group Cormorant Defenders International. They feel they should be protected.

It’s up to biologists like Jim Farquhar of New York’s Department of Environmental Conservation to find the balance between human needs and cormorants.

Farquhar: “We have needs too, as people.”

Karen: “And we’re competing with them.”

Farquhar: “And we’re competing with them in some cases. Hopefully, if we can inject good science, we make good decisions as a result.”

The biologists’ biggest effort has been on Lake Ontario. They’ve been destroying nests there — and killing some adults – for ten years. Farquhar says they’re finally seeing results.

They’ve reduced the cormorant population on the lake by about two-thirds, and the fishing’s improved.

Now, the biologists are trying to have the same success on the St. Lawrence River. But they’ve only seen a 13% decrease in the number of cormorant nests and they’ve been doing it for four years.

Part of the challenge is that most of the birds live on Canadian soil where management is left to the landowner.

Local anglers like Steve Sharland of Ogdensburg, New York, are frustrated with the slow progress.

“They should eliminate them. They’re not a Northern New York bird and what they’re doing to our fisheries is a sin.”

That’s a common misconception. Actually, the cormorant is native to the region but few people have seen them in such large numbers.

Sharland says some people are so frustrated, they’ve been shooting the birds illegally. But Jim Farquhar believes those are isolated incidents.

“Mike just mentioned that we’ve got some black-crowned night herons nesting out here. It’s another species we’re concerned about, and one we’ve been trying to actively protect from the cormorants. So that’s a good sign.”

A good sign. But it’s another species trying to live on this small patch of land. And the biologists’ balancing act has become even more delicate.

Fighting for the Control of a River

In the dry American West, folks have been
duking it out over water for centuries.
But water shortages are new to the Southeast.
Many once thought the rivers would flow
forever. Now, North Carolina is emerging
from the worst drought in over a hundred
years. Julie Rose reports on a power
struggle has erupted over one of its
rivers:

(sound of inside a truck)

From a one-lane road way above the Yadkin River, the trees are so thick you can just see
the water. It looks so tranquil that the Narrows Dam is a bit of a shock when you turn the
bend.

Rose: “Whoa, this thing’s huge.”
Ellis: “Yeah.” (chuckles)

(sound of climbing out of the truck)

I’m with Gene Ellis, who’s the head of Alcoa Power Generating.

(sound of water falling.)

For nearly 100 years, the aluminum company has owned and operated four dams on one
of North Carolina’s largest rivers. Now Alcoa is trying to renew that hydropower license
for 50 more years. But the Governor of North Carolina wants Alcoa’s dams for herself –
or rather for the people of North Carolina.

The federal law that governs America’s rivers does allow for a takeover, but it’s never
been done. And Alcoa’s Gene Ellis says it’s something he’d expect of a dictator.

“Alcoa’s only experience with the socialization or the nationalization of a plant was
in Venezuela during the leadership of Hugo Chavez.”

Ellis says the takeover attempt violates Alcoa’s property rights. Trouble is that while
Alcoa owns the dams, the people of North Carolina own the river. Alcoa’s basically a
tenant.

And North Carolina Governor Bev Perdue says it’s time to end the lease.

“We need to be sure that the water sources that we are allowing to be controlled – if
you will – by a private industry, produces something for North Carolina.”

Something like jobs, says Perdue, which is why Alcoa built the dams in the first place.
They used to power an aluminum smelter that was the main employer in the region.

In 2002, Alcoa closed the smelter, but still makes millions off the dams. It sells the
hydropower wholesale. Alcoa continues to pay taxes – and still offers free swimming
and fishing on the lakes – but the Governor says that’s not enough to deserve 50 more
years of control on the river.

Officials from at least seven counties agree. As do many residents, like Roger Dick.

“The state needs to be in control. We do not need to be, as citizens, having to go ask
a global company for how we will use our water.”

Ironically, Alcoa’s biggest support comes from towns on the four lakes it manages.
Especially Badin – where you can see the huge, empty smelter from the steps of the
mayor’s office.

Rose: “Did you work there?”

Harrison “Yes. 30 some years. That was our only industry and we’ve lost our heart
when we lost Alcoa.”

And yet, Badin Mayor Jim Harrison says-

“I would rather trust who I know than who I don’t know. Does the state not run our
highways? Do you really think they have done the best with our highways that can
be done? So, I’m mean, if they do the same job with our dams, what’s that gonna
end up being?”

Not even Governor Perdue can answer that yet. Nor is it clear how the transfer would
work or what the state might have to pay for it. Those decisions are up to the Federal
Energy Regulatory Commission, which oversees thousands of hydropower licenses, but
has yet to take one over.

Talking to Mark Robinson – the commission’s director of energy projects – you can
practically hear him scratching his head through the phone line.

“We really can’t figure out what the idea was there. But I’m sure with the help of a
number of very smart lawyers we would all figure it out.”

Since Alcoa expected a decision on its license this summer, lawyers on both sides are
already working overtime.

People across the country are watching closely, because the outcome will set an
important precedent at a time when water is no longer the endless resource many once
thought.

Eating Asian Carp

There are rivers in the Midwest that are just flush with fish. Normally, that would be great, but these are two species of invasive Asian Carp – and they shouldn’t be there in the first place.
These foreign fish breed so quickly and grow so large, they push out native fish species. There are entrepreneurs who dream of getting rid of Asian carp.
Shawn Allee looks at what they’ve cooked up and whether it could do any good:

One businessman wants to take on Asian carp.

He’s John Holden and he started up the brand-new Heartland Processing company.
When I visit his factory in central Illinois, Holden walks me around his machines.

They transform fresh carp into fish oil and dry fishmeal. Holden says the fishmeal might make good pet food.

He’s tested it his own dog.

“He just inhaled it. You got more of that for me?”

Unfortunately, there are no carp today – and I have to settle for a dry-run demo.

John Holden is a doctor by trade, but he started his business after he watched Internet video of carp in the Illinois River.

“I went onto YouTube, and I said, this is nuts.”

“What did you see when you went onto YouTube?”

“Fish jumping like it was boiling water. The most poignant one was the department of natural resources one. All of a sudden they’re jumping out of the river, and smacking the DNR people.”

Actually, a guy from the state Department of Natural Resources is on-hand to vouch for this. He’s Chris McCloud.

“We’ve had conservation police have their teeth knocked out.”

“You’re kidding me.”

“Oh no.”

McCloud says the state wants to cut back the carp population – not out of some vendetta, but because silver and big-head Asian carp pretty much took over the Illinois river from native fish.

McCloud says the agency’s got a plan.
Commercial fishing fits into it.

“It basically says, let’s see what this can do and then determine how much processing would be needed to make a dent in a population that’s so voracious.”

Now, my question is: Will massive, commercial harvesting of carp really work? I mean, the Illinois river’s 275 miles long, and I’ve seen videos that it’s thick with Asian carp.

To get an informed opinion, I head to the Illinois Natural History Survey.

Kevin Irons works there – he tracks carp populations along the Illinois River.

“As biologists we’re very encouraged by the Heartland Processing plant and commercial fishermen that are taking the fish out. From some of the research we’ve looked at, the only way we can reduce the numbers is by commercially harvesting them”

Irons walks me through his argument.

To start, he opens a freezer.

“These are the ones that will jump out and hit ya.”

“This one’s like 2.5 feet long.”

“That’s a relatively small one. There are many that are 3-4 feet long.”

Irons says the two troublesome varieties of Asian carp are native to Russia, the Mideast and China.

They’re small in China – they’re super-sized here.

“Nowhere else in the world do we have populations like this because they’re over-fished everywhere else. People in the YangTze River rarely see them over 4-5 pounds because they’re taken soon in their life cycles.”

How big can they get here?

“The world record was taken in St. Louis – nearly a hundred pounds.”

Irons says Chinese and other ethnic food markets in the US sell Asian carp but most Americans won’t touch them.

“We might go to a restaurant and get a walleye or perch fillet – they’re boneless and they’re beautifully done. These can be just as tasty, but they have bones. My wife, if she gets a bone in her fish, she’s just about done; she doesn’t want to mess with the bones. We’re pretty spoiled.”

Irons says if most Americans won’t eat Asian carp, maybe processors like Heartland can pick up the slack by making them into pet and animal feed.

It might not eliminate carp, but Irons says it might get darn close.

If it works too well – and Heartland runs out of fish on the Illinois River – Irons says there are plenty of carp waiting for processing in the Mississippi and other rivers.

Insecticide Chemical Is a Powerful Greenhouse Gas

  • Sulfuryl flouride, a chemical used to fumigate termite-infested buildings, is a potent greenhouse gas (Source: Esculapio at Wikimedia Commons)

The federal government is going to take some significant steps to reduce global warming gases. Carbon dioxide is the main target, but there are other types of greenhouse gases. Lester Graham spoke with one researcher who found a potent greenhouse gas lingers in the atmosphere much longer than previously thought:

Transcript

We hear a lot about carbon dioxide as a greenhouse gas. But there are other chemicals that trap heat and contribute to global warming. One of them is an insecticide used to fumigate termite-infested buildings. It’s called Sulfuryl fluoride. That insecticide is four-thousand times better at trapping heat than carbon dioxide. It’s been estimated that Sulfuryl flouride hangs around in the atmosphere for five years or so… but new research shows that it lasts a lot longer than that:

Mads Sulbaek Anderson is working with other researchers at the University of California-Irvine published a study in the journal Environmental Science and Technology.

He’s with us now… first, how is this termite insecticide used?

“Well, it’s used in a number of applications. What the fumigators do is, they basically cover the house in a giant tent. And then you fill up the house with this compound, and over the span of a few days, one or two days, this compound acts like a pesticide- it kills all of these bugs. After that time span, you remove the tent, and make sure that all of this compound evaporates and dissipates.”

What did you discover about how long this insecticide actually stays in the atmosphere?

“The usual routes by which pollution is removed from the atmosphere has to do with reactions, and there’s something called an OH radical, a hydroxyl radical in the atmosphere. That’s the usual cleaner of the atmosphere. In this case, this radical didn’t react at all with the compound – we couldn’t detect anything.”

Is this a significant contributor to global warming, or greenhouse gases?

“It’s still a question of how much is actually present in the atmosphere right now. But, we know how much is used every year of this compound. And so this compound, right, it’s 4,000 times more efficient in trapping the heat compared to carbon dioxide. But of course, there’s not much of it out in the atmosphere yet. But it’s more a precautionary tale, because other compounds are being phased out for other reasons and so sulfuryl fluoride could take over for those applications, if we don’t think twice about this. And it stays around for at least a few decades. So, it’s not an enormous problem by itself- we have to focus on the real problem, which of course is due to emissions from burning fossil fuels. But this compound too contributes to the warming of the atmosphere, or could potentially do it.”

Mads Sulbaek Anderson is a researcher at the University of California-Irvine. Thank you.

“You are very much welcome.”

Saving Nation’s Seed Supply

Some small gardening businesses
are noticing more customers want organic
and heirloom seeds. Experts think that
trend might be important for the world.
Kinna Ohman reports they believe
those seeds might be the hope of future
food supplies:

John Meshna points to a half empty rack of vegetable and flower seed packets in his
store.

“We’ve emptied this thing at least a half a dozen times this year. I thought maybe
we’d have a rush in the spring and that’d be the end of it. And it looks like it’s
going to be going through the winter.”

Meshna owns and runs DirtWorks – a green garden supply business in New Haven,
Vermont. He’s been selling organic and heirloom garden seeds for more than twenty
years. Heirloom seeds come from vegetables that have almost disappeared. And Meshna
thinks people want those types of seeds more and more because they’re worried about our
food supply.

“People call us just to make sure sometimes before they order, now, ‘these are really
organic seeds, right?’ Yeah, it says it right on the label. It’s gonna make you very
happy when you get that package.”

And it’s making certain experts happy too.

Hope Shand is the research director of Etcetera Group. It’s an organization that’s
concerned about corporate control of the food supply. Shand says when more home
gardeners and small farmers grow plants from organic and heirloom seeds, that helps
keep variety in the world’s food supply.

“This is an incredibly important service. People, gardeners, small farmers, urban
gardeners, are conserving, and saving seed diversity. No one else is really doing that
job.”

Hope Shand says multinational corporations started taking control of seeds around thirty
years ago. Now, Shand says, ten corporations own over half the world’s commodity seed
supply. And she thinks that’s risky.

“The seed is the first link in the food chain. Whoever controls the seed literally
controls the world’s food supply. We can’t afford to have the level of vulnerability
and dependence that that entails when we have a handful of multinational seed
companies controlling the world seed supply.”

(sound of watering)

“I’m growing greens without heat.”

At a small organic nursery in Hinesberg, Vermont, Julie Rubaud is one of those who
wants to get these seeds and plants to more people. For her, it’s not just preserving a
strain of a vegetable, it’s trying to match up those plants with the right gardener.

Rubaud grows close to eight hundred varieties of organic and heirloom plants for her
customers. She says that helps her connect people with the right plants for their gardens
and tastebuds.

“I always start out asking, ‘how much room do you have?’ And then I ask them
how they like to eat tomatoes. It’s nice to be able to cater everyone’s garden plan to
their individual needs because we have so many varieties.”

And if next year’s anything like last year, Rubaud will have at least forty varieties of
organic tomato plants ready for new gardens by next spring.

She wonders – with the economy the way it’s been – if one plant might do exceptionally
well.

“There’s Radiator Charlie’s Mortgage Lifter Tomatoes. Have you heard of that
one?” (laughs)

Radiator Charlie’s tomato has been around since the 1940s. You probably won’t find it
at the big-box discount-store gardening department. It’s one of those colorful, hardy,
productive plants that many people think will help bring back variety to our food supply.

Budget Cuts to Fuel Ash Borer’s Spread?

US senators are asking the Department of Agriculture for emergency
funding to help control the spread of the emerald ash borer. The
burrowing tiny insect has already killed millions of ash trees. The
emergency funding request comes as Congress has severely cut federal
funding for the program. That’s forced states to change the way they
fight the spread of the beetle. The GLRC’s Mike Thompson reports
because of the federal budget cuts and a lack of state funding, experts
fear the infestations could spread:


(Sound of chainsaw and worker)


In 2002 the emerald ash borer was first discovered in southeastern
Michigan. Soon after that federal and state officials determined the
chainsaw was the best way to fight it.


(Sound of tree falling)


Since the tiny beetle arrived, officials estimate the insect has killed – on
its own – more than 15 million trees in Michigan, Indiana and Ohio, and the
infestations keep spreading.


There is no known natural predator for the ash borer; no known
pesticide. The experts believe the only way to stop it is to destroy it by
cutting all ash trees within half a mile of a known infestation.


Dan Herms is an entomologist at Ohio State University. He serves on the
ash borer science advisory panel. He says the beetle threatens all of
North America’s 8 billion ash trees.


“If the spread of the insect can’t be contained to Michigan, it will
continue to spread to Ohio and throughout the Eastern United States,
killing all the ash trees. Essentially it’s going to do to ash what
Dutch elm disease did to elm and what chestnut blight did to chestnut.”


Over the past two years the three infested states have cut down
hundreds of thousands of ash trees to stop the spread, but cutting was the
preferred method when the federal government was picking up the tab.


In 2004, the federal government allocated some 41 million dollars for
protecting and cutting down ash trees. That funding slipped to 27
million dollars last year. In 2006 the federal government ash borer
funding has dropped to 8 million dollars – just one-fifth of what it was
two years ago.


Getting at the reasons for the budget cut is difficult. State agriculture
officials defer to federal agriculture officials who defer to Congress.


The U.S. Department of Agriculture’s Ash Borer Program coordinator
Craig Kellogg theorizes the war in Iraq and Hurricane Katrina forced
lawmakers to cut funds.


“We can always speculate between all the other programs that are going on at
USDA, the cost of war, the cost of the hurricanes and the clean-ups and
all that good stuff, but we are not at the level that we were given the full
reason why we were cut.”


So with little federal money, most of the pre-emptive cutting of ash trees
has stopped. OSU entomologist Dan Herms says he’s concerned.


“It worries me extremely because if the funding is not restored such to
allow at least the opportunity to stop the spread of the insect in northwest
Ohio it will spread throughout the eastern United States, and it will cost
hundreds of billions of dollars in damage.”


The USDA and the states have shifted focus. States will use the federal
funding they receive to monitor the spread of the insect, enforce
quarantines and educate the public. Ohio will cut trees only if they find
new infestations away from the northwest part of the state.


But if the threat is so great to Ash trees, why won’t the states spend their
own money to stop the spread of the emerald ash borer?


We asked Ohio Agriculture Department spokeswoman Melissa Brewer.


“Well, you know, the state has stepped up to the plate as far as having in kind services
and taking those programs and running with them. You know, as far as how much
money can be contributed and that kind of thing… I don’t know who to even direct you on that.”


Officials from the different states say with current state budget pressures,
it’s difficult to find the money to cut down ash trees, and now that
federal money has dried up, Indiana scientists say they’re not sure
cutting trees worked.


State officials and scientists say the emerald ash borer is a national
problem and it should be the federal government’s responsibility to pay
the protection costs.

Combating Inland Invasives

Invasive plants, fish and other creatures are threatening many inland
lakes. Evironmentalists and property owners are trying to stop the
spread…before the invaders dramatically alter the smaller bodies of
water. The Great Lakes Radio Consortium’s Ann-Elise Henzl reports:


It’s strange to think that plants and animals from Europe, Asia and Africa
are living in small lakes in the Midwest. Boaters have taken invaders
there…after picking them up in the Great Lakes.


The big lakes are home to more than 160 aquatic invasive species,
including Eurasian Watermilfoil. The stringy plant grows in thick
clusters that get up to 12 feet tall.


“I have seen lakes where if you fell out of the boat in these massive
weeds and you weren’t wearing a life jacket, I don’t care how good a
swimmer you are, you would sink. You can not struggle your way
through these thick entanglements of weeds.”


Ted Ritter leads an effort to reduce aquatic invasive species…in
Wisconsin’s Vilas County.


(Sound of pontoon motor)


On one afternoon he takes his pontoon boat on a lake that had an
infestation of Eurasian Watermilfoil.


“It is a very aggressive plant and it has no natural predators to control its
growth, it grows up to two inches a day.”


When Eurasian Watermilfoil finds conditions it likes, it takes over
quickly. A piece as small as two inches can break off, and float away to
create a new plant.


Eurasian Watermilfoil is widespread in northern Michigan… northern
Wisconsin and other places. It’s one of dozens of aquatic invasive
species on the move in the region.


One of the worst invaders is zebra mussels. They can ravage a lake’s
ecosystem.


(Sound of motor boat)


So far, they’ve made it to just one lake in northern Wisconsin. Mike
Preul with the Lake Superior Chippewa scuba dives there, to count the
mussels. Three years ago, he found 7 adults per square meter. This year,
he counted more than 14-hundred:


“They’re still increasing. What they’ve seen in other systems is that just
like with any other exotic species they’ll come in, the population will
explode, they’ll kind of eat themselves out of house and home, and then
they’ll come down to a level and reach a steady state.”


No method has been discovered to get rid of zebra mussels, but there are
ways to control some invaders.


Herbicides can be used to kill Eurasian Watermilfoil, and some property
owners chip in to buy aquatic insects to kill the plants.


Les Schramm did that on his local lake:


“As the larvae hatches it burrows into the stem of the Eurasian
Watermilfoil and sort of eats out the center vascular part, and it falls over
and dies.”


People fighting aquatic invasive species say it’s like fighting weeds in a
garden — the work never stops and it can be expensive.


Ted Ritter of Vilas County says it costs thousands of dollars to treat a
lake once. So, often people do nothing.


Ritter says that can hurt the environment. He says it can also threaten the
economy, in areas like northern Wisconsin that rely on tourism.


Ritter says the invaders can reduce the appeal of a lake. He mentions a
plant called “curly leaf pondweed.” When it dies in the middle of
summer, it creates algae blooms that look like slimy green pillows:


“When people arrive at resorts and they look out and they see that very
unappealing lake they say ‘I’m not staying here,’ and they go somewhere
else. When realtors bring prospective buyers out to look at a property,
people get out of their car and they go right to the lake and they say ‘oh
my, I’m not even interested in looking at the house. This lake is
horrible.'”


Because it’s so difficult to control invasive species, Ritter and others
fighting the invaders focus on prevention.


Local volunteers and workers from the Wisconsin Department of Natural
Resources spend hours at boat landings. They urge people to clean their
boats, trailers, and fishing gear thoroughly when going from lake to lake,
that can keep unwanted plants and creatures from traveling along.

More Trees Lost to Emerald Ash Borer

A tree-killing beetle continues to spread through the region. The beetle has left millions of ash trees in its wake. Now
it’s spread into northeast Indiana and will cost one city there much of its
natural beauty. The Great Lakes Radio Consortium’s Jeff Bossert
reports:


A survey of ash trees in Decatur by the state’s Department of Natural
Resources shows the emerald ash borer has been wreaking havoc there
for some time on some trees, as long as 4 or 5 years. So, the city recently
announced it would spend 1-million dollars to cut down about 15-
thousand of them.


The ash borer slowly kills trees by making tunnels under the bark and
cutting off the food supply.


City Forester Dwight Pierce says the trees are almost entirely
infested. He hopes this move will end any concerns of the ash borer
showing up elsewhere in the state.


“We don’t want to let it spread out of our city and get into adjoining
cities, and spread farther south in the state. We’re still hoping we can
control it here before it gets down to south of Indianapolis and it turns
into a whole forest again. We obviously don’t want to let it get into
that.”


Pierce says the beetle likely came from firewood brought in from
infected areas in Michigan or Ohio… and he hopes residents of Decatur
heed warnings about moving firewood across state lines.
