At this time of year, one of the nation’s most exotic
birds is nesting, and many wildlife lovers are rejoicing. Once
close to extinction, the Eastern population of sandhill cranes
has grown dramatically. In fact, their numbers are so big that
they’re becoming a problem in some places – and there’s talk of
starting a hunting season for cranes. The Great Lakes Radio
Consortium’s Sandy Hausman has the story:


(Sound of marsh and birds)


It’s a cool spring morning, just before dawn. Brandon Krueger is watching a stretch of marshland along a country road in Central Wisconsin. Krueger works for the International Crane Foundation. He’s taking part in the annual Midwest crane count. Celebrating its thirtieth year, thousands of volunteers have fanned out across parts of Wisconsin, Michigan, Minnesota, Illinois and Iowa to look and listen for sandhill cranes.


“It’s a great sound to hear when you’re waking up. This is usually the earliest that I ever get up during the year. It’s a real struggle, but it can be worth it – for some of the things that you hear and the opportunity to see cranes.”


(Sound of crane call)


Krueger hears a breeding pair a half a mile away – exchanging what’s known as a unison call. The birds are big – up to five feet tall. A hundred years ago they made easy targets for hunters. In the 1930’s, naturalist Aldo Leopold lamented the loss of cranes – nearly hunted to extinction in Wisconsin. He knew of only 25 breeding pairs of sandhills in the state. But the federal government made it illegal to hunt cranes, and the state started working to restore bird habitat. Today, crane lovers celebrate an impressive comeback.


“I’ve talked with our leading field ecologist and he’s estimated upwards of forty-thousand sandhill cranes in the Midwest area.”


This year’s crane count is still being tallied, but Krueger heard nine birds and saw three flying by.


(Sound of cranes)


In the county next door, Troy Bartz claims to see many more birds than that on a daily basis.


“I’ll come home and it’s nothing for me to see two, three-hundred cranes in a field in one crack.”


Bartz has been farming for 13 years – growing corn, soy beans and alfalfa on nearly a hundred acres near Nina Creek.


(Sound of plow)


“Plants started disappearing out of the field with crane tracks right next to them. They go right down the row and they pull the shoots out of the ground and eat the kernels off the roots. I lose thousands of plants every year.”


The International Crane Foundation says damage in Wisconsin alone could total $100 million, and for family farmers, a year’s profit could be lost.


Bartz: “On the small acreage that I’m tilling, you can’t lose thousands of plants and not have some kind of an impact. That’s hundreds and hundreds of bushels I’m losing.”


Hausman: “And what’s the cash value on that?”


Bartz: “I figure anywhere between two to three-thousand dollars minimum every year.”


Hausman: “So what do you think the answer is?”


Bartz: “Shoot ‘em.”


Hausman: “Really?”


Bartz: “Yeah!”


There is some talk of having a hunting season for cranes, but that would require approval from the U.S. Fish and Wildlife Service, and many critics say the eastern population of sandhills is too small to permit hunting. The Wisconsin Department of Natural Resources says there are alternatives for farmers – machines called banger guns that make explosive sounds every few minutes. Troy Bartz’ neighbor, Mel Johnson, tried that, but found the birds quickly got used to the noise.


“The DNR warden brought the guns out. He said the best way is to mix a few regular shells in with it, he said, because it won’t scare ‘em away, the guns. He’s been taking them out for years, and he said they won’t scare any wildlife away – them guns.”


They’ve also tried scarecrows and colored ribbons but they didn’t work either. Farmers have had success with a product called Kernel Guard – a pesticide that made corn seeds taste bad to cranes, but this year the manufacturer stopped making it because one of its active ingredients can be toxic. Crane advocates are now asking the EPA to allow use of another chemical that’s already sprayed on golf courses to repel geese, but approval is not expected this year.


(Sound of cranes)


So crane lovers are keeping their fingers crossed – hoping farmers won’t be breaking the law by shooting the birds.

States Aim to Draw in Women Hunters

If you look at the average hunting camp, you’d see about six men for every woman. But some state officials want that to change. They think getting more women and girls into the shooting sports will help turn around declining sales of hunting licenses. And they say that will help shore up state funds that pay for conservation.

If you look at the average hunting camp, you’d see about six men for every woman. But
some state officials want that to change. They think getting more women and girls into
the shooting sports will help turn around declining sales of hunting licenses. And they
say that will help shore up state funds that pay for conservation. The Great Lakes Radio
Consortium’s Sarah Hulett reports:


“Okay, ladies… Is everybody done dry firing? All right. Safety on, actions open. The
coach will insert one round into the chamber…”


Today is the first time Abby Wood has ever shot a gun. Abby’s 13 years old, and she’s at
a mid-Michigan shooting range with about a dozen other daughters and their moms for a
day of gun safety instruction and target shooting.


Abby loads and shoots five rounds. Then she and her mom, Ann Miller, walk downrange
to check out her target.


“I got ’em all on the target, and they’re sort of in the same area. But they’re a little off.
And I got one really close to the bull’s eye, I’m kinda proud of that. (Ann:) I thought we
did great.”


The Michigan Department of Natural Resources put on this mother-daughter event as a
way to get more women and girls interested in target shooting and hunting. Like many
states, Michigan is seeing a slow decline in hunting license sales – about one percent a
year. And some worry that if that trend continues, it could hurt the state’s ability to pay
for conservation programs and to keep its wild deer herd in check.


Lynn Marla coordinates a state program that puts on workshops for women to develop
their outdoor skills. She says of all the outdoor sports, hunting is the most difficult
activity to get women interested in.


“It’s basically ‘never been invited. Never been taught.’ I mean, I know a man who’s my
age and he had three daughters and a son. And he never even thought to ask his
daughters.”


But some states are extending invitations to women and girls who want to learn to shoot
and hunt. The Becoming an Outdoors Woman program – or BOW – started in Wisconsin
in the early 1990s. BOW is now in 43 states, seven Canadian provinces, and New
Zealand. Every year, about 20-thousand women spend a weekend hunting, fishing, and
learning other outdoor activities like paddling and orienteering.


Christine Thomas is BOW’s founder, and a professor at the University of Wisconsin. She
says it’s important to get different kinds of people interested in outdoor activities.


“Because – especially as budgets shrink, but really anytime – as people have less of a tie
to the natural resources, they are less likely to care what happens to them. So from a
standpoint of political support for fish and wildlife programs, environmental protection, I
think it’s important to get lots of people involved. And women and girls are some of
those people.”


At the rifle range, Mart McClellan says she didn’t grow up around hunters, and she used
to be opposed to hunting. But she says working with people who hunt has changed her
attitude, and she’s interested in trying it.


“You know, it seems like in the past, from my perspective, it’s been such a sexist kind of
sport…that doesn’t need to be. And I think a lot of women and girls get intimidated.
Because you know you hear the stories about deer camp, it’s all the guys, and guy
bonding. So I think this will kind of combat that stereotype. And hopefully get more
women out hunting.”


This is the Michigan Department of Natural Resources’ first shooting event for women
and girls. Abby Wood – the teenager who’s shooting for the first time – says she likes
target shooting – and she thinks she might want to try hunting too. And after a day on the
shooting range littered with rifle shells, she’s got some ideas about what she might want
to wear to deer camp.


“I want to make earrings out of the leftover shells…”

Can Carp Eggs Get Around Barrier?

By summer’s end, officials from the Army Corps of Engineers and the

By summers end, officials from the Army Corps of Engineers and the state of Illinois hope to finish an underwater electric barrier in a canal just south of Chicago. The barrier is designed to repel invasive fish such as the Asian Carp. But some environmentalists fear the barrier won’t be enough to keep the voracious, non-native species out of Lake Michigan. The Great Lakes Radio Consortium’s Shawn Allee reports:


Some conservationists worry Asian Carp may someday enter the Great Lakes by simply hitching a ride.


These critics say leaky ships passing through the electric barrier could hold carp eggs inside their ballast tanks and deposit them on the other side. But local officials say that scenario is unlikely.


Steve Stuewe is with the Illinois Department of Natural Resources.
He says Asian Carp eggs need turbulent water, and if they do find their way into rusty ballast tanks…


“They will probably be dead because they’ve settled out into the bottom of the hull and they’ve either suffocated or they’re down there, mixed in with the iron oxidate. So, they sink. They have to float.”


The research on egg viability is still sketchy, but a federal study of the issue may settle the question once and for all early this summer.


Just as the Asian Carp begin to spawn.

River Otters on the Rebound

  • Now that the river otter's population is recovering, some worry that they are plundering fish farms. The proposed solution to this problem is stirring up some debate. (Photo courtesy of the U.S. Fish and Wildlife Service)

There have been many wildlife success stories in the region. For instance, the numbers of white-tailed deer and Canada Geese have rebounded so strongly that many consider them pests.

There have been many wildlife success stories in the region.
For instance, the numbers of white-tailed deer and Canada Geese
have rebounded so strongly that many consider them pests. Now,
another animal is being added to that list. The Great Lakes Radio
Consortium’s Bill Cohen reports on the rebound of the river otter:


In the late 1980’s river otters were so rare in Ohio that wildlife officials imported 123 of the animals and released them along rivers and streams. Now, it’s estimated that Ohio has more than 4,000 river otters. Dave Scott helps track the Ohio numbers for the Natural Resources Department.


“River otters are a really neat success story. And like some other wildlife things, they’ve done better than anticipated.”


In fact, so much better that the otters in Ohio are now being blamed for eating up fish in stocked ponds and in farm lakes where fish are raised for sale. That’s why wildlife officials are now proposing a trapping season here next winter. Trappers value river otters for their fur and back the idea of a trapping season but animal protection activists oppose it. They say the foothold traps that are used are inhumane.

Owls Crossing Border Into U.S. For Food

Transcript

Candian owls have been moving from their native habitat into the United States, including MN, WI, MI, and IA. Researchers say the number of owls making the trip is unprecedented. The Great Lakes Radio Consortium’s Christina Shockley reports:


The Great Gray Boreal , northern hawk, and snow owls live in
the upper reaches of Canada. But hundreds of owls have been flying into the U.S. in search of food. The small mammals they prey on in their native range, like mice, voles, and lemmings, are in the midst of a population crash. Susan Foote-Martin is with the Wisconsin Department of Natural Resources. She says it’s common for small-mammal populations to rise and fall. So, even though the owls expend a lot of energy to get here, their stay is temporary.


“They’ll definitely move back. They’re only down here because the population of the animals they eat are down. But there’s also another consideration, and that’s deep snow cover in the areas where they normally live.”


Foote-Martin says the owls have a hard time catching their prey because they burrow deep into the snow. She says if the owls continue to fly into the U.S. over several years, it could signal a problem in their native habitats.

Tough Wetlands Law Falling Short

Data suggest that this region continues to lose wetlands despite pledges
from politicians to the contrary. The latest evidence comes from one state
in the region that has some of the toughest laws on the books. The Great
Lakes Radio Consortium’s Mark Brush has more:


After looking at wetlands data from 1994 to 2003, the Minnesota Department of
Natural Resources found that overall the state has lost close to 5,000 acres
of wetlands. This despite the fact that the state has a policy of “no net
loss of wetlands.”


Julie Sibbing is with the environmental group the National Wildlife
Federation. She says states like Minnesota need more than strong laws to
stop wetland destruction:


“You can pass really good state laws to protect wetlands, but if you don’t
adequately fund those programs and if you don’t have the political will to
get the people on the ground and give them the mandate to enforce the law,
you’re really not going to get anywhere.”


Sibbing says to effectively enforce their laws, states need to invest more
in monitoring programs that closely track what’s actually happening on the
ground.

Feral Pigs Run for the Border

Ag officials are tracking a big pig problem across Wisconsin. Since 1999, growing numbers of feral swine have appeared across the state. And as the Great Lakes Radio Consortium’s Brian Bull reports, officials now fear the spread of the wild pigs:


The woolly porkers have appeared in 23 of Wisconsin’s 72 counties. They’re damaging crops, digging out ground-nesting birds, and killing small deer. They may also cary pseudorabies and swine brucellosis, threatening domestic pigs.


Wayne Edgerton is agricultural policy director of Minnesota’s DNR. He says the problem could easily spread into his territory.


“They can certainly walk across the ice, so this time of the year they can come across to Minnesota. And I’ve heard they’re actually good swimmers. So even in summertime, they could get their way over to northern Minnesota.”


Some people have speculated that Minnesota’s intense winters would kill off any feral swine crossing the border. But Tim DeVeau, a veterinary medical officer of the USDA, says that’s unlikely.


“As long as they’ve got food, and they’re gonna put fat on, they’ll be well-insulated.”


DeVeau adds that in order to keep wild pigs’ numbers under control, at least 75% of the population has to be destroyed every year. He says that’s not happening.

Smaller Fish After Alewife Die-Off

This past year, the size of salmon in some Great Lakes is getting smaller because
their main food
source is dying off in some areas of the lakes. The Great Lakes Radio Consortium’s
Lester
Graham reports:


In the 1960’s, fish and game officials introduced Pacific salmon such as chinook,
coho and
steelhead to control the invasive species alewife. That’s a small fish that moved
in from the
Atlantic. The salmon are popular fishing. But since the alewives are not native…
they’re
especially susceptible to quick weather changes. And fisheries managers suspect
competition
with zebra mussels for food also affects alewives. Recently, alewife populations
have crashed in
some places. Jim Dexter is with the Michigan Department of Natural Resources…


“The primary reason that there are not alewives in Lake Huron and you get
fluctuations in Lake
Michigan is related more to the climate. You know, now, zebra mussels are tied into
that, into the
equation at some point but not probably to the affect that the climate is having on
those.”


So, without as many alewives, salmon don’t have as much to eat… and they’re smaller
than usual.
Fisheries managers say the effect is probably temporary.

Timber Wolves Moving Into New Area

  • Timber wolves have been making a comeback in the Midwest for some time. Recently, they've been reappearing in places they haven't been seen in decades.

Timber wolves are moving into an area where they
haven’t been seen for about 80 years. The Great Lakes Radio Consortium’s Lester Graham reports:

Timber wolves are moving into an area where they haven’t been seen for about 80 years. The Great Lakes Radio Consortium’s Lester Graham reports:


Timber wolves have been repopulating areas of Minnesota, Wisconsin, and the upper peninsula of Michigan for some time now. But recently, a wolf was shot and killed in the lower peninsula of Michigan. Since then, tracks of two more wolves have been identified not too far away from the shooting. The two peninsulas of Michigan are separated by water five miles across the connect Lake Michigan to Lake Huron. Sometimes, it freezes over. Michigan Department of Natural Resources biologists figure a small pack of wolves made the trek across the ice. Brian Roell is with the DNR.


“Well, it’s interesting that, you know, wolves are, you know, repopulating areas that, you know, they’ve been removed from. It’s really nice to see that these wolves are making their own comeback.”


Hunters are warned to be careful when trapping or hunting. The wolves are still federally protected. The wolf shooting this fall was ruled accidental because the trapper shot the animal thinking it was a coyote, since wolves were killed off in the area decades ago.

Biologists Find Deer Devouring Rare Flowers

Most of us think of the white-tailed deer as a graceful and cherished part of the natural scene. But it turns out when there are too many deer, it’s bad for some of the plants in the forest. New research suggests deer may be a prime culprit in a worrisome loss of rare plants in the woods. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:

Most of us think of the white-tailed deer as a graceful and cherished
part of the natural scene. But it turns out when there are too many
deer, it’s bad for some of the plants in the forest. New research
suggests deer may be a prime culprit in a worrisome loss of rare
plants in the woods. The Great Lakes Radio Consortium’s Stephanie
Hemphill reports:


Gardeners in many suburbs and rural areas know deer are good at
mowing down hosta, tulips and other favorite plants. In the woods,
deer munch on the small plants that live on the forest floor… plants
such as orchids, lilies, and other wildflowers.


Fifty years ago, researchers at the University of Wisconsin surveyed
hundreds of acres in the state, and made careful records of the plants
on those sites. In those days, the deer population was a lot lower
than it is now. In the last couple of years, two biologists went back to
many of those same sites and counted the plants living there now.


Tom Rooney says at most sites they found fewer different kinds of
plants.


“It tends to be the same species occurring over and again on the site.
You’re losing the rare species and picking up more and more
common species.”


He says they tried to link the decline in rare species to the fact that
the forest is getting older. But they found no evidence for that.
Instead, lead researcher Don Waller says the evidence points to
deer, which have increased dramatically over the last fifty years.


“The worst changes we’ve seen, ironically were in a couple of state
parks and a protected natural area, that showed losses of half or
more of species in 50 years. However, in these sites there was no
deer hunting, implying high densities of deer may be causing a lot of
the effects we see in the woods.”


Plants that rely on insects for pollination declined more than other
types of plants. Waller thinks it might be because the insect-
pollinated plants have showy flowers, which could catch the eye of a
wandering deer. As the flowering plants decline, the insects and
birds that rely on them for food could decline as well – bees, moths,
butterflies, and hummingbirds.


Waller says it’s worrisome because scientists don’t know how
particular insects and plants work together to support each other.


“As we’re losing parts of the ecosystem, we’re really not sure what
their full function is, they might play some crucial role we’re not aware
of and only too late might we become aware of the fact that this loss
led to an unraveling or threats to other species.”


Waller says the only places they studied that still have a healthy
diversity of plants are on Indian reservations. The Menominee Tribal
Forest in northeastern Wisconsin is pretty much like it used to be fifty
years ago.


(forest sounds under)


In this forest, there are only about ten deer per square mile. That’s
about as low as the deer population gets in Wisconsin. It’s not that
the tribe is hunting more deer; it’s the way the forest is grown.


Deer find lots to eat in young aspen woods; there’s less for them to
eat where pines and oaks and maples grow. Don Reiter is the wildlife
manager here. He says in the 360 square miles of the Menominee
forest, there’s really four different types of woods.


“We have pulpwood, we have northern hardwoods, white pine, red
pine, and again, the forest ecosystem as a whole, there’s plenty of
food out there for the deer.”


And because there aren’t too many deer, young pines and hemlocks
– and orchids and lilies – have a chance to grow.


In the upper Great Lakes states, wildlife officials have been trying to
thin the deer herd for several years. That’s because state officials
have been aware deer were causing problems by eating too many
plants. The recent study provides dramatic evidence.


In Minnesota, for instance, hunters are shooting four times the
number of deer they shot fifty years ago.


Steve Merchant is forest wildlife program consultant for the
Minnesota DNR. Merchant says the agency has liberalized its rules,
to encourage hunters to kill even more deer. But the number of
hunters hasn’t gone up in recent years. And lots of private
landowners post no-hunting signs.


“We need to have some help from people, people still need to get out
and hunt deer, and landowners need to provide that access for
people to harvest deer.”


Merchant says Minnesota is gradually trying to restore pine forests,
which were cut down for lumber and replaced with fast-growing
aspen. More pine forests could cut down on the deer population…


“But as long as we still have the strong demand for the aspen
markets that we do, and we manage those aspen forests in a
productive manner for wood fiber, we’re going to create a lot of good
white-tailed deer habitat.”


Merchant says it would take decades to change the woods enough to
reduce the deer population. And in the meantime, we’re losing more
and more of the rare flowers.
