Dozens of whooping cranes are heading north this spring, as an
experiment continues to develop a migrating flock of the birds in the
Eastern U.S. Wildlife experts hope this’ll be the year the effort will
produce its first successful hatch of a crane egg. The GLRC’s Chuck
Quirmbach reports:
About sixty of the endangered whooping cranes migrate between the
southeastern U.S. and northern states like Wisconsin and Michigan.
Last summer, for the first time, a few cranes paired off and produced
eggs, but the cranes didn’t stay near their nests and predators destroyed
the eggs.
Rachel Levin of the U.S. Fish and Wildlife Service says this year she’s
more optimistic the cranes will reproduce.
“We have cranes this year that are going to be five years old. Whooping
cranes reach sexual maturity between three and five years old. So, we
are hoping this year that we have cranes that will produce eggs and that are
maybe mature enough this year to stay with those eggs and do their
parental duty.”
One goal of the crane reintroduction project has been to have 25 adult
breeding pairs. For now the project will continue to add to the flock by
bringing in crane chicks from Maryland.

Some states and Native American tribes in the Upper Midwest say they’re
looking forward to taking over management of their gray wolf
population. That’s if a new federal plan to de-list the wolf as an
endangered or threatened species becomes law. The GLRC’s Chuck
Quirmbach reports:
The federal government says the grey wolf population in Minnesota,
Michigan and Wisconsin combined is roughly 4,000. That’s large enough
for the Interior Department to recommend letting the states take over management
of the wolves. State or tribal officials could eventually allow
individuals to get permits to shoot wolves that are killing livestock.
Or, the states could even propose wolf hunting seasons. But a group
that has worked to increase the number of gray wolves across the U.S.
wants no hunting allowed.
Nina Fascione is with Defenders of Wildlife.
“This is a population that’s still fragile, even if it is technically
recovered under the auspices of the Endangered Species Act.”
The Interior Department says it would take a close look at wolf kill
projections before going along with any hunting plan. Public hearings
on the proposal to de-list the gray wolf as endangered or threatened
will take place this spring.

Environmentalists and the U-S Forest Service often fight over the best way to balance between cutting timber for lumber and paper, and preserving wildlife habitat. Lately, the battle is over whether government just looks at each tract of land where it sells timber or whether it looks at the cumulative impacts of logging on National Forests.

Environmentalists and the U.S. Forest Service often fight over the best
way to balance between cutting timber for lumber and paper, and
preserving wildlife habitat. Lately, the battle is over whether
government just looks at each tract of land where it sells timber or
whether it looks at the cumulative impacts of logging on National
Forests. The GLRC’s Chuck Quirmbach reports:
When some people look at a stand of trees they see lumber for a house or
wood for paper.
“Let’s go to the yellow birch.”
But when Ricardo Jomarron spots a stand of yellow
birch trees, he sees a valuable home for the pine marten – a member of
the weasel family. The marten is endangered in some states.
“The great thing about yellow birch is that it has a propensity to become
hollow while staying alive. So you have this wonderful den for pine
marten and other species to rear their young that isn’t going to blow over
in a windstorm.”
Jomarron is standing in the Chequamegon-Nicolet National Forest in
northern Wisconsin that’s near the border with Michigan. Last year,
Jomarron’s group, the Habitat Education Center won a federal court case
that has blocked timber sales on about 20-thousand acres in the million
and a half acre Chequamegon- Nicolet.
A judge ruled the Forest Service had violated the National
Environmental Policy Act by not considering the cumulative impact of
logging on other forest species. Logging not in just one place, but many
can have a larger impact on some wildlife that the judge said the Forest
Service didn’t consider.
But it’s not just the act of cutting down the trees that worries the
environmentalists. It’s the loss of shade that some plants need to survive
and new logging roads crossing streams where erosion damages trout
habitat.
The Chicago-based Environmental Law and Policy Center is representing the
Habitat Education Center. Attorney Howard Learner says the case is not
about banning logging in the national forests. He says it is about
restoring a system that he argues has gotten out of whack.
“In part because the Forest Service was looking at one timber sale and what the
impacts of that were, and then they’d look at another one and what the impacts of that were, and
they didn’t look at the overall impact – and what was the forest rather
than the trees.”
The Forest Service eventually decided not to appeal the judge’s rulings to
stop the disputed sales in this one forest. It’s taking another look at the
cumulative impact of the proposed deals, but the Forest Service says it
didn’t approve the timber sales without getting advice from state and
tribal experts on water and wildlife.
Chequemegon-Nicolet forest supervisor Anne Archie says her agency
has done a good job. She says if you really want to study the total effect
of forest management, look back a century when loggers cut everything
in sight.
“70 to 100 years ago there was no national forest. It was shrub land and
burnt over grassland. Now the National Forest is there that provides a
habitat for the species. So cumulatively in 70 to 100 years, we’ve been
growing the habitat for the species that Habitat Education Center…we’ll
we’re all concerned for those species.”
But Habitat Education Center and other environmental groups say the
Forest Service still isn’t doing a thorough job of determining the impact
that logging might have. The environmentalists and conservation groups
say the agency’s follow-up study on the Chequemegon-Nicolet is like
Swiss cheese with many more holes than substance. Depending what
happens at the end of the current comment period, the groups could ask
the judge to keep the lid on the timber sales.
Logging companies that cut and mill the trees from the forest are not
happy about the legal battles.
James Flannery runs the Great Lakes Timber Company. He says if you
want to look at the cumulative impact to the forest, you should look at
the cumulative impact to the economy of the area.
“Part of the money generated from forest sales comes back to
communities. If we have no forest sales and there’s thousands of acres of
forests land that we harvest I’m more worried about the income of these
communities, which will be zero.”
But the environmental groups argue the broad expanse of the forests
need to be protected from multiple timber sales that cumulatively could
cause wider ecological damage. They say ignoring the health of the
forest ignores another important industry of the area: the tourism that
brings a lot of money to the north woods.

A disease that infects deer and elk has been alarming wildlife officials
and hunters for years, but now it seems the disease could be more
dangerous than previously thought. The Great Lakes Radio Consortium’s
Christina Shockley reports:
Chronic Wasting Disease, or CWD, affects the brain tissue of deer and
elk. Sponge-like holes form in the brains of sick animals. The deer
begin to waste away, become weak, and then die.
Since CWD was discovered in Colorado nearly forty years ago, wild deer
in nine other states have tested positive for the disease. Little is known
about CWD – including how to stop it.
What scientists do know is that the infectious proteins-called prions –
thought to cause CWD are found in the brain and spinal cord areas of
infected animals, but officials still don’t have the answer to the big
question.
Judd Aiken is a professor of Animal Health and Biomedical Sciences at
the University of Wisconsin.
“The ultimate question is whether venison from infected animals, CWD infected
deer, poses a risk to humans. Clearly the first question that needed to be
asked and addressed was whether there was infectivity in muscle.”
Recent findings say there is.
Researchers at the University of Kentucky injected muscle from an
infected deer into the brains of genetically altered mice. The mice
displayed signs of CWD. This is the first time the infectious proteins
blamed for CWD have been found in deer meat.
The finding raises questions about whether eating venison is safe.
Researchers including Aiken say the study is important, but has limits.
For example, he says it doesn’t replicate what would happen in real life.
Plus, he says it’s probably unlikely humans can even get CWD. He says
studies suggest it’s difficult for the disease to jump to other species. Still,
he urges caution. Hunters should get the meat tested before they eat deer
from an area where CWD has been found.
“I, in no way, can advocate the consumption of infected deer, and indeed,
I would suggest due to the limitations of the CW tests, I don’t advocate
the consumption of deer obtained from a CWD endemic area.”
Even if the test comes back negative, Aiken says a negative result isn’t
always accurate, and infected animals in the beginning stages of the
disease can look and act normal.
(Sound of sporting goods store)
John White is a deer hunter from Sheboygan, Wisconsin. He’s in the
hunting section of a nearby sporting goods store. White isn’t too
concerned about Chronic Wasting Disease.
“Not a whole lot of people are worried about it. I mean, when it first
came out, some people were a little leery about it and didn’t want to hunt
that year, but they kinda got over it. I’m not really worried about it being
in the meat at all, because by the time the test comes back I’ll probably
have the deer eaten already and then it’s already too late.”
State wildlife officials say… that’s not a good idea. They recommend that
if you hunt deer in areas where the disease has been found, get the deer
tested before eating it. That message hasn’t changed… since learning the
prions could be in the meat. Some argue… it should change.
John Stauber is with a government watchdog group in Wisconsin, and
is co-author of “Mad Cow USA: Could the Nightmare Happen Here?”
He says officials are keeping quiet about the risk of CWD so they don’t
lose revenue from hunting licenses.
A large portion of state conservation agency budgets are dependent on
fees from hunting licenses. He says all deer that die should be tested for
the disease. Stauber also says CWD is a major human health concern.
“The biggest risk might not be the people who would die from
eating venison, but rather, the people who would die from the
contamination of the blood supply. This is a problem that would unfold
not in days or months or years, but even over decades.”
Stauber says it’s just a matter of time before Chronic Wasting Disease
spreads to people… he says some might even have the disease already,
and not know it.
But researchers like Judd Aiken from the University of Wisconsin say
people shouldn’t over-react.
“People should be concerned, but I don’t want people to panic, either. If
you think you may have consumed venison from infected animals, I don’t
think it’s likely that you’ll ever develop a human prion disease.”
But, Aiken says there’s too much we don’t know about the disease, and
since studies can take years to complete, we might be in the dark for a
while longer.
New research shows the infectious material believed to cause Chronic Wasting Disease can be found in the meat of infected deer. Previously, it was thought that only the brain and central nervous system areas of deer or elk carried the fatal disease. The Great Lakes Radio Consortium’s Christina Shockley reports:

New research shows the infectious material believed to cause Chronic
Wasting Disease can be found in the meat of infected animals.
Previously, it was thought that only the brain and central nervous system
areas of deer or elk carried the fatal disease. The Great Lakes Radio
Consortium’s Christina Shockley reports:
The authors of the study at the University of Kentucky say anyone
handling or eating deer infected with CWD may be inadvertently
exposed to the disease.
The research shows that for the first time the mutated proteins – called
prions – can be present in deer muscle.
Officials in states with CWD in wild deer say their message to hunters
won’t change:
Get deer tested for CWD, and don’t eat deer that test positive.
Jim Kazmierczak is Wisconsin’s State Public Health veterinarian.
“What this demonstrates is that the CWD agent does occur in deer
muscle. What it does not address is the question of human
susceptibility to Chronic Wasting Disease.”
Kazmierczak says it’s still unclear how – or if – Chronic Wasting Disease
could be transmitted to humans.
Officials say a new outbreak of Chronic Wasting Disease
could erupt after a fence was cut at an infected hunting preserve in Wisconsin. The Great Lakes Radio Consortium’s Christina Shockley

Officials say a new outbreak of Chronic Wasting Disease could erupt after a fence was cut at an
infected hunting preserve in Wisconsin. The Great Lakes Radio Consortium’s Christina
Shockley reports:
Authorities say someone intentionally cut a hole in a perimeter fence at the preserve in central
Wisconsin. They say tracks indicate deer had gone in and out of the area through the hole…
before the owner saw it and notified the Department of Natural Resources.
Alan Crossley is with the Wisconsin DNR. He says officials shot deer around the preserve to try
to limit the chance the disease would spread to wild deer.
“We have to try to assess whether any deer escaped from that shooting pen. Then we’re going to
be meeting to talk about okay, should we try to do any additional shooting of deer in a larger area
around that pen.”
Crossley says it’s now even more important to monitor deer near the preserve in the years ahead.
He says it will take time to determine how their overall efforts to combat the disease are working.
So far, CWD has been found in the wild in ten states, including Wisconsin, New York and
Illinois.
Mild winter weather is shutting down logging operations across the region. The Great Lakes Radio Consortium’s Erin Toner reports:

Mild winter weather is shutting down logging operations across the
region. The Great Lakes Radio Consortium’s Erin Toner reports:
Rain and mild temperatures have caused the ground to thaw, making
logging impossible in some places.
Al Steege is with the Keweenaw Land Association in Ironwood in
Michigan’s Upper Peninsula. He says logging in the UP is down about
75 percent for this time of year.
“I’ve been here ten years, I don’t remember a winter quite like this.
We’ve had winters where there’s been a lot of snow and that has caused
some issues with us logging, but as far the temperature-wise, I don’t
remember the ground situations being quite like they are this year.”
Steege says the UP needs single-digit temperatures for several nights in a
row to get logging production back up. The winter logging season runs
through mid-March. Some areas in the UP, Minnesota and Wisconsin
can only be logged in the winter because they stay too wet in the
summer.
Port officials are wary about new state regulations intended to keep invasive species out of the Great Lakes. Several states are working on laws that would tighten restrictions on ballast water in foreign ships. The Great Lakes Radio Consortium’s Bob Kelleher reports:

Port officials are wary about new state regulations intended to keep
invasive species out of the Great Lakes. Several states are working on
laws that would tighten restrictions on ballast water in foreign ships. The
Great Lakes Radio Consortiums Bob Kelleher reports:
Proponents hope to keep creatures like zebra mussels from getting
established in the Great Lakes. The non-native plants and animals arrive
in ship ballast water, carried from overseas ports.
Adolf Ojard is the Duluth Seaway Port Director. He says a state-by-state
approach to regulate ballast water is the wrong approach.
“We’re not the only area that is dealing with invasive species. Every
harbor and estuary around the world has a similar concern. It needs to be
dealt with on an international and world level, so that it can be a level
playing field for everybody out there that is involved in transportation.”
Michigan has passed new rules with stiff fines for ships with untreated
ballast water. Wisconsin and Indiana are expected to consider similar
rules; and Minnesota’s Attorney General says he’ll propose the
regulations this spring.
Some populations of gray wolves could be taken off the endangered species list. The U.S. Fish and Wildlife Service is expected to issue proposed new rules for gray wolves in the upper Great Lakes region in the next week or so. We have more from the Great Lakes Radio Consortium’s Tracy Samilton:

Some populations of grey wolves could be taken off the endangered
species list. The U.S. Fish and Wildlife Service is expected to issue
proposed new rules for gray wolves in the upper Great Lakes region in
the next week or so. We have more from the Great Lakes Radio
Consortium’s Tracy Samilton:
The growth of the grey wolf population in the Great Lakes area is good
or bad, depending on who you talk to. Wolves help control deer herds,
but they also prey on livestock.
Adrien Wydeven is with the Wisconsin Department of Natural
Resources. He says in extreme cases, states might want to let farmers
who’ve had problems shoot wolves they catch in the act of killing
livestock.
“And we could consider the possibility of a public harvest of members of
general public applying for permits to trap or hunt wolves in limited
areas.”
There will be a 90-day public comment period before the delisting of
Great Lakes wolves is adopted. It will apply mainly to wolves in
Michigan, Wisconsin, and Minnesota. Each state will also have to adopt
its own wolf management plan.

Researchers began a program to reintroduce whooping cranes in the
eastern U.S. in 2000. This winter, some young cranes are learning how
to migrate south from older birds. The biologists tracking the birds say
so far, the new recruits are catching on. The Great Lakes Radio
Consortium’s Christina Shockley reports:
At first, humans led the new flock of whooping cranes from Wisconsin
to Florida by flying ultra light planes. Now, some of those birds are
teaching a few younger cranes how to make the trip.
Kelley Tucker is with the International Crane Foundation, one of the
groups involved in the reintroduction project. She says this winter, four
young whooping cranes are flying with older cranes and sandhill cranes
on the migratory path. They’re relying partly on instinct, partly on the
lead of the older birds.
“The birds will be a couple miles apart, but some of the biologists have
said ‘I have a sense that the younger birds know where the older birds
are.’ Sometimes they’ll roost within a mile or two of the older birds.”
Tucker says eventually she hopes all the chicks will learn to migrate
from older birds, and the ultra light planes won’t be used. She says it’s
important for the cranes to make it back to Wisconsin in the spring to
mate.
