Researcher Rolf Peterson has spent more than 30 years studying moose and wolves on a remote
wilderness island in Lake Superior. Peterson says moose on Isle Royale are suffering from
warmer-than-usual weather in recent years. The Great Lakes Radio Consortium’s Stephanie
Hemphill reports:
There are 750 moose on Isle Royale. That’s down from 900 last year.
Isle Royale has had hot summers and warm, snowless winters most years since the 1998 El Nino.
Peterson says when summers are hot, the moose don’t eat enough. And they have to fight off
more ticks.
They spend a lot of time grooming when they should be feeding, and they lose a lot of blood,
potentially. It could be in the winter when they’re not in very good condition, they have to
replace their entire blood supply over a period of a few short weeks.
Meanwhile, wolves on the island are taking advantage of the weakness of the moose. Last year
there were 19 wolves; this year, 29. But Peterson says the wolf population will eventually
decline, as there are fewer moose to eat.

A hotly debated environmental issue goes on trial this week. New York’s notorious Deer Lady
faces criminal charges of breaking the state’s feeding ban. Some states, including New York,
have imposed bans hoping to stop the spread of Chronic Wasting Disease. The fatal brain disease
has been found in deer and elk as far east as Wisconsin. But many animal activists say they don’t
understand the need for feeding bans. For the Great Lakes Radio Consortium, Joyce Kryszak
followed the Deer Lady into the park . . . and to the deer:
Anita Depczynski is almost deer-like in appearance herself. The sixty-three year old retired
cleaning woman, now arthritic, is spirited, but a bit timid moving. And her big brown eyes peer
skittishly at those who recognize her in the park where she still goes to feed the deer.
“Are you the Deer Lady?”
“No, I’m not.”
This shy, relative newcomer to animal advocacy tries to avoid the attention the year-long case has
focused on her. Still, Depczynski isn’t easily frightened away. About a dozen deer, many she
calls by name, make their way across the snow covered path to greet her. They huddle around as
the Deer Lady scatters corn near her feet.
“Faline, that’s enough now, because I don’t have much. See? You can’t come in here with this
little bag like this – forget it.”
Depczynski faces up to forty-five days in jail if found guilty of breaking the state’s feeding ban.
But Depczynski says she won’t stop. As we trudge along the cold, windy nature trail, she
suddenly stops to explain. Depczynski says the deer living in this park would starve without her.
“I’m afraid about going to jail…but I have to stand my ground. Many people before me have been
brought down.”
Depczynski says people were feeding the deer in this park, long before she arrived. But she says
most have been intimidated to stop, or else deny they still do because of the new feeding ban.
Most of the park visitors we meet say they support Depczynski. And most say they don’t
understand what Chronic Wasting Disease and the feeding ban are all about.
Despite the confusion, wildlife experts say the feeding ban is necessary. They say it’s part of the
effort to stop the spread of Chronic Wasting Disease. The disease hasn’t hit this part of the world
yet. But the bans are intended to prevent the introduction of Chronic Wasting Disease. Experts
say the bans help discourage deer from artificially congregating together. And that’s important,
because it’s believed Chronic Wasting Disease could be passed along through deer feces and
urine. Wildlife expert Joel Thomas says he knows Depczynski and others think they’re helping.
But Thomas says this isn’t a Disney movie. And he says feeding wildlife, especially deer, is
never a good idea.
“It sustains them, and that’s all it does. And in the long term, it really upsets herd health when
people get involved with feeding them. We feed deer the wrong things, we feed them at the
wrong time, we feed them for the wrong reasons. So, they’re just not a species that benefits from
that type of human intervention.”
And Thomas says there’s scientific evidence suggesting that the well-intentioned meddling could
do a lot more than throw off the balance. He says it could encourage the spread of Chronic
Wasting Disease and devastate the North America’s deer population.
“If the deer are left to browse, and live their lives, largely without this type of artificial
concentration that we provide with feeding, then any kind of disease – Chronic Wasting or
otherwise – that enters into an animal population, won’t be spread so fast so severely. It’s a health
check, if you will. It’s kind of like a fire wall.”
But the Deer Lady, Anita Depczynski, says that’s an imaginary firewall in this case – and in many
other suburban areas. She says generations of the same deer have been congregating in her park
and being fed by residents for years. She says they’re trapped here, surrounded by houses and
highways. And she says when they have to go looking for food, the results are heart wrenching.
We saw that, first hand, a little while later on the trail.
“Oh no, look he’s wounded? Look at his leg, it’s infected…I know, they told me about her
yesterday. Leave her alone. I don’t want her destroyed. See what happens?”
The yearling stood shaking on three legs in a thicket along the trail. Her fourth leg was ripped off
below the hip, presumably by a car. The DEC came later that day, and put her down.
Depczynski says the deer was another casualty of the state’s feeding ban. But wildlife expert Joel
Thomas says it’s nature taking it’s course.
“Not all animals are intended to survive in a population. It’s population dynamics, it’s biology, it’s
nature, it’s the way the planet spins.”
And Thomas says to interfere with that is to risk the spread of diseases – such as Chronic Wasting
Disease – that could wipe out an entire species. But Depczynski believes New York is over-
reacting to a disease that is still many states away.
“If I thought I was harming wildlife, I’d be the first one to stop.”
Wildlife experts say convincing people like Depczynski is the biggest challenge in their fight
against Chronic Wasting Disease. Because they say, by the time the presence of the disease is
obvious, it’s already too late.

Many wildlife lovers consider moose to have a special mystique. Adult moose are bigger than
horses, and they seem fearless. But biologists don’t know much about many moose populations.
A team of researchers is just beginning to learn about one herd of 4,000 moose in the
northwoods. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:
Half a dozen big four-wheel-drive pickups are parked at a boat landing on MacDougal Lake. It’s
about 30 miles west of the Lake Superior shore, in the heart of the Superior National Forest in
Northeastern Minnesota. The forest is twice the size of Delaware.
It’s 25 degrees. At the edge of the frozen lake, men in conservation officer uniforms are standing
around a small fire. They’re waiting to hear from the helicopter. The crew on the helicopter is
shooting moose with a tranquilizer gun. They need to get up close to the animals to learn more
about them.
Scientists think more moose could be living in this area. Mike Shrage is a biologist with the
Fond du Lac band of Chippewa. He says they’d like to know why there aren’t more moose here.
There are several possible reasons.
“Wolves, bears, lack of habitat, hunting and other kinds of human-related mortality, automobile
accidents.”
Shrage is listening to a radio cradled in a canvas holster on his shoulder. He cocks his head to
catch every word.
“There’s three of them there.”
The helicopter crew has spotted some moose.
“Yeah, I think they’re bulls.”
“These are three bulls. It’s not uncommon this time of year, you’ll get small groups of them
hanging together for awhile. Little bachelor groups.”
Shrage says the helicopter crew will try to chase one of the moose into an open area, like a frozen
lake, where they can get an easy shot.
“And if it lays down right in the lake, then they can sit down on the ice next to it. It makes
everything a lot easier.”
“Yeah, he’s gonna hopefully drop in the spot where they can get right to him.”
“I think they must already have a dart in him and they’re just waiting for it to take effect.”
The helicopter drops off a crew member to stay with the moose, and comes back to the boat
landing to pick up a radio collar.

Counting moose is a challenge. A recent survey in this area showed a drop from 5,000 to 4,000
animals in one year. But researchers admit there could be a 25% margin of error in those figures.
That’s because it’s hard to find the moose in heavily wooded areas. The collaring project will
make counts more accurate.
Three biologists are gathered around the latest moose to be fitted with a collar. He’s a mature
bull. He’s lying on his side in the middle of a huge frozen swamp.
He’s blindfolded to make the process less stressful. He seems to snore, while the biologists poke
and prod.
They take blood samples to check on hormones and blood chemistry, and to look for disease.
They also pull a tooth to send to a lab. They can get an exact age by measuring the rings on the
tooth.
Glenn Delgiudice takes notes on the animal’s fat reserves. That’s a good indication of its overall
health.
Delgiudice even uses an ultrasound machine to measure the fat in the moose’s rear end.
“Rump fat is one of the main fat depots of these animals, and also one of the first to go. They
mobilize their fat depots generally in a sequence. So we measure the depth of the fat with
ultrasound.”
Another key indicator of the animal’s health is the condition of its hair. This moose has most of
its hair. They aren’t all so lucky. Some of them have scratched a lot their hair off.
<"Rick yesterday saw a calf of one of our cows that was what'd you say Rick, only 25% hair. So
that one's been rubbing and scratching for a long time. And, of course, when they're doing that
rubbing and scratching and biting, they're not foraging, and it can drain them over time."
The collar has to fit just right. If it’s too loose, a moose can get a foot caught in it. If it’s too
tight, it can bind, especially in the fall mating season when the bulls’ necks get thicker.
“Yep, that looks good.”

Finally the moose is given an antidote to the tranquilizer, pain-killer, and sedative that have kept
him immobile for about half an hour.
“You know, you’ll see his ears twitch, and he’ll start to lift his head,” Delgiudice says. “The
moose are better at getting up than deer typically. They just get up, loosen up a little bit, and
then lope away.”
The moose struggles up, stands for a minute, and then saunters off toward the trees.
That’s moose number five for the day. The team is planning to track 60 moose for five years.
It’ll tell them what kills these moose and what’s keeping the population from growing.

Over time, invasive species have upset the natural balance of the Great Lakes. Now, officials are
working frantically to stop a new threat, the Asian carp. The carp lives in tributaries connected to
the Great Lakes. But there may be another route into the water system – through Asian food
stores. As the Great Lakes Radio Consortium’s Karen Kelly reports, live carp can be purchased
in many cities throughout the region:
“This one in Chinese, layoo. This one in Chinese…”
York Alooah stands in front of a crowded fish tank at the 168 Market in Ottawa, Canada’s capital.
He points to the fat, foot and a half-long bighead carp swimming behind the glass.
The fish are brought to his store by truck from Toronto. They originate at farms in the southern
U.S.
Speaking through an interpreter, Alooah says it’s unlikely that a carp could escape during
delivery.
“They use a big truck and have the fish tank inside.”
Alooah says the fish can’t jump out because the tanks are covered. Still, the live sale of these fish
has many people worried. That’s why states like Indiana, Michigan, Minnesota and Ohio have
banned the possession of live Asian carp.
Several states are also asking the federal government to add these carp to a list of invasive species
considered harmful. That listing would make it illegal to possess them alive.
In Canada, there aren’t laws like that on the looks. But officials say they’re considering action.
Nick Mandrack is a research scientist with the Canadian Department of Fisheries and Oceans. He
says Canadian researchers are keeping an eye on an Asian carp population that’s moving north up
the Mississippi River. They worry that the fish will migrate through a manmade canal into the
Great Lakes.
“If they were to become established, either through dispersal up from the Mississippi or
unauthorized release as a result of the live food trade, they could have enormous impacts on the
Great Lakes ecosystem, which would likely result in a dramatic decline in the biomass of game
fishes.”
That’s because two species of Asian carp eat the same food as small forage fishes. And those
forage fishes are what the larger gamefish rely on. The Asian carp are too big for the gamefish to
eat.
Researchers are also worried about two other species. The black carp could wipe out endangered
mussels that live in the lakes. And the grass carp destroys aquatic plants where native fishes live.
Mandrack has seen both the bighead and the grass carp sold live in Asian food stores. He and
others say that poses one of the greatest threats to the Great Lakes fish population.
(sound of fish scaling)
Back at the 168 market in Ottawa, York Alooah uses a long knife to butcher and scale a fish he’s
pulled out of a tank. He laughs when an interpreter asks if people ever leave his store with live
carp.
“When people buy, it’s not alive. He clean and kill and clean everything.” Is it never alive?”
“Never.”
In fact, the city of Chicago is hoping to guarantee that doesn’t happen. Officials want stores that
sell live carp to operate under permits. And the fish would have to be killed before it left the
store.
But not all fish is bought for consumption. There’s also concern about a Buddhist practice in
which captive animals are released into the wild.
Tookdun Chudrin is a nun with the MidAmerica Buddhist Association. She says the carp sold in
food stores are not likely candidates for release.
“I think that people would not buy such a large fish for liberation because they tend to get very
small animals and very often will put them in a pond at a temple.
And Chudrin says, Buddhists would want to know if the religious practice was harming other
animals.
“I think definitely if there were a sign saying that said putting these fish in the lakes could be
detrimental to other species, I think people for sure would heed that if this was going to endanger
others and the people knew it, I don’t think they’d do that.”
So far, only two Asian carp have been found – in the Canadian waters of the Great Lakes.
Another was released in a fountain in Toronto, just a few blocks from Lake Ontario.
Whether from pranks, or acts of kindness, some fear it’s only a matter of time before more carp
get into the water. They say the Great Lakes could become a giant carp pond, and many of the
species we’ve come to know would disappear.

A test flock of whooping cranes is winging its way north from Florida to Wisconsin this month.
That makes wildlife officials who are trying to restore the flock very happy. The Great Lakes
Radio Consortium’s Chuck Quirmbach reports:
The Whooping Crane Eastern Partnership is setting up the only migrating flock of whoopers in
the Eastern U.S. Almost two dozen birds are taking part and wildlife officials hope to teach
flying skills to another 20 crane chicks this summer.
Beth Goodman is whooping crane coordinator at the Wisconsin Department of Natural
Resources. She says the numbers show the experiment is on track.
“It underscores we set a goal that seems reasonable, and our goal is establishing 25 breeder pairs
and 125 migrating birds in the eastern migratory flock by the year 2020.”
The whooper was at its greatest danger of extinction sixty years ago when there were only 15
birds counted in the wild. The new flock already has exceeded that number. Goodman says one
of the tougher tasks this year will be raising enough private money to keep the project going
strong.
