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.

Santa’s reindeer are not doing
so well. Rebecca Williams reports
one group wants to get them on
the endangered species list:

Caribou, also known as reindeer, are declining all over the globe. The group International Fund for Animal Welfare says two subspecies of caribou are in especially bad shape.

Nathan Herschler is with the group. He says these caribou live in the Arctic. And climate change is making their lives miserable.

“Instead of soft snow that’s falling on the ground, we’re getting freezing rain. That’s encasing the land in ice and the caribou are literally starving to death.”

Herschler’s group wants the US government to put the caribou on the endangered species list. Even though the caribou live in Canada, he says the listing would help by banning the import of caribou or caribou meat into the US.

New ‘Deer Crossing’ Technology

  • The Colorado Department of Transportation is trying out a new system to detect deer about to cross the highway (Photo courtesy of the US Fish and Wildlife Service)

accidents. Rebecca Williams has more:

Every year there are about 1.5 million
deer-car accidents. Now highway officials are
testing a new system to cut down on those
accidents. Rebecca Williams has more:

There are some animal detection systems that use lasers or infrared motion
sensors. But those systems can be tripped by tumbleweeds or small animals.

In Colorado, highway officials are testing a new device.

Nancy Shanks is with the Colorado Department of Transportation. She says
they’ve buried cables along each side of the highway. The cables emit an
electromagnetic field. When an animal crosses a cable a warning sign with a
picture of a jumping deer lights up.

“It will detect a change in the field to the tune of a large animal. The system
will not pick up a smaller animal – a skunk or a rabbit, mouse.”

This cable system isn’t cheap. The pilot project costs 1.2 million dollars.

But Shanks says if this system works out, the price should come down a bit
over time.

Study: How Chronic Wasting Disease Is Spread

A new study finds that deer can spread a fatal brain wasting disease through saliva and blood. Rebecca Williams reports the researchers say this means no part of an infected animal should be considered safe to eat:


Chronic wasting disease or CWD, affects deer, elk and moose, and it’s always fatal. CWD has been found in animals in 14 states and two Canadian provinces. Up until now, exactly how the disease spreads between animals has been a mystery.


Now a study in the journal Science shows evidence deer can spread CWD in their saliva and blood. Edward Hoover is the study’s lead author.


“No part of an infected animal is currently recommended to be consumed by people and these findings just underline that, that in addition to nervous system, the lymphoid system, we’d have to consider all parts certainly inappropriate for human consumption.”


Hoover says right now there’s no evidence people are susceptible to CWD, but he says scientists also can’t rule it out yet.

Developing New Test for Deer and Elk Disease

Chronic Wasting Disease is killing wild deer and elk. And it’s slowly spreading to new areas in North America.

Chronic Wasting Disease is killing wild deer and elk. And it’s slowly spreading to new areas
in North America. Right now, tests for the disease are done after the animals are dead,
but researchers say they might be getting closer to a test that can be given to live animals.
The GLRC’s Christina Shockley reports on what this might mean in the fight against the disease:


Chronic Wasting Disease, or CWD, causes deer and elk to waste away and die.
The disease is causing hunters and wildlife officials to worry about the
future of the wild deer population. Right now, testing a brain sample from a
dead animal is the sure-fire way to detect the infectious protiens, called prions, that
cause the disease.


Alan Young is a Veterinary Science professor at South Dakota State University.
He’s developing the new test.


“Our ultimate goal is basically to develop a test for infectivity in blood,
by taking a blood sample, and then analyzing for the presence of the infectious prion protein.”


Young says a blood test would let deer and elk farmers know if their herds are
infected before the animals die. He says the research could also lead to a cure for CWD.

Could Humans Get Chronic Wasting Disease?

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 Concern Over Chronic Wasting Disease

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.

New Chronic Wasting Disease Worries

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.

Deer hunting season is coming to an end across the region, but some
people keep shooting deer despite the laws telling them not to. As the
Great Lakes Radio Consortium’s Erin Syth reports, these poachers might
want to pay close attention to what they’re shooting at:


Wildlife officials throughout the region are using robotic deer to catch
poachers. The deer’s head and tail move by remote control. When a
hunter attempts to shoot the deer, wildlife officials move in.


Robo-deer are made from polyurethane foam and real hide. The latest
version is known as the “Stomper.” It retails for 17-hundred dollars, and
comes standard with a stomping front leg.


Brian Wolslegel is owner of Custom Robotic Wildlife, Incorporated. He
says these deer definitely work.


“Some guy was telling me about a guy that shot a decoy. They took his
gun, fined him – I think it was $2,000 and moved their operation a mile down
the road, and two hours later the same guy came back and shot at it again with
a different gun.”


Conservation officials in Wisconsin report that one robo-deer can rack up
to 30-thousand dollars in collected fines for the state.

Hunting Feral Pigs

As hunting season nears, many wildlife officials across the upper
Midwest are asking hunters to line up their sights on snouts and
tusks, as well as antlers. The Great Lakes Radio Consortium’s Brian Bull explains:


In Wisconsin alone, feral pigs are roaming through 27 counties. The
animals are damaging crops and hurting native ecosystems, and have
even killed small deer. And since an adult sow can wean up to a
dozen piglets a year, their numbers are hard to control.


Bryan Woodbury is a wildlife damage specialist with the Wisconsin DNR.
He says hunters should feel free to bag any feral pigs they meet – but
they should first make sure they’re not someone’s livestock.


“They’re not the distinct pink color, or the black and white style –
they tend to be darker color with longer hair, the boar may have a tusk
that you can see… they will pose a threat if you get up close to them
and tease them or threaten them in any way, they may do a charge or try
to fight back just like any other wild animal would try to do. But
their main instinct is to run away.”


Woodbury adds that feral pigs should taste just as good – if not
better – than those on the farm. Besides Wisconsin, many other
states are having problems with feral pigs, including Illinois,
Indiana, Ohio, and Pennsylvania.
