News of a zoo being investigated and fined has reignited the debate over keeping elephants in captivity. Rebecca Williams reports:
It’s just been revealed that the Los Angeles Zoo was fined for the death of an elephant back in 2006. The zoo does not admit any wrongdoing.
But some people believe keeping elephants in zoos is wrong.
Suzanne Roy is with the group In Defense of Animals. She says elephants in captivity often have foot problems from standing on hard surfaces.
“It’s just incredible the level of suffering these elephants are put through before they eventually literally can’t stand on their own feet or legs anymore.”
But the Association of Zoos and Aquariums says its zoos have to meet high standards of care for elephants.
Paul Boyle is the group’s senior vice president for conservation.
“There are no people more committed to keeping elephants in good health and humor than those professionals at zoos across the country.”
Some zoos have stopped keeping elephants. Some, because they feel they can’t provide the best care for elephants any more.

For animals in most zoos and aquariums, the door from
freedom to captivity only swings one way. But at the
Monterey Bay Aquarium, sea otters from its exhibits teach
wild sea otter orphans how to survive in the ocean. Ann
Dornfeld has the story:
Rosa has her baby in a headlock. That’s actually how
southern sea otters hold their young.
“The pup is essentially unconscious – it’s very much
asleep, and Rosa is holding it as a female would in the
wild: she’s got it sort of teed off to her side with a paw
around its neck.”
Andy Johnson is the director of the Monterey Bay
Aquarium’s Sea Otter Research and Conservation
program.
By the end of the19th century, sea otters had been hunted
to extinction in some parts of the Pacific.
Lilian Carswell is with the U.S. Fish and Wildlife Service.
She says these days, pollution and disease are sea otters’
biggest threats. And she says a lot of other species
depend on otters’ survival.
“Sea otters are important for a number of reasons. One is
that they’re a top predator in the nearshore marine
ecosystem and they play an important role in structuring
what that ecosystem looks like.”
Hungry sea otters keep sea urchin populations in check.
When urchins overpopulate an area, they can mow down
entire kelp forests that provide food and shelter for
hundreds of species.
So to help conserve the otter population, Andy Johnson
and his team at the Monterey Bay Aquarium pair orphaned
pups from the wild with the female exhibit otters. The goal
is for the surrogate mother to not only care for the pup, but
also to teach it all the skills it will need to be released back
into the wild at about six months old.
A volunteer has just tossed some food into the pool where
Rosa and the orphaned pup are swimming. Rosa grabs
the live crab as the pup watches.
“Rosa’s quite skilled with those, so she’ll pretty much take
that apart in a few minutes. We’ll have to watch the pup
and see if the pup approaches the crab without getting
pinched. I have to admit it’s quite amusing to see these
young animals confronting these crabs ’cause these crabs
are pretty formidable on their own.”
Rosa ends up breaking off a leg for her adopted pup, who
decides the shell is too much work. Before long, though,
the pup will learn some of the same impressive skills that
adult sea otters have – like how to use tools to open clams
and sea urchins.
Before the surrogate program began, workers and
volunteers used to hand-rear these pups. They’d even
take the pups swimming in Monterey Bay to acclimate
them to their future home.
But that made the released otters expect food from
boaters and other people they encountered in the bay.
Now that surrogate moms raise the otters, the goal is for
the pups to never see or hear a human. We’ve been
watching the sea otters interact from a TV monitor near
the pool. To get up close to the pup, I have to put on a
Darth Vader costume of sorts – starting with a huge black
nylon poncho.
(sound of the poncho)
Ann: “This is a welding mask?”
Andy Johnson: “A very cheap welding mask.”
Rosa isn’t fooled. As I approach the pool, she shoots over
to see whether I have food.
(sound of the otter sniffing around)
Rosa was a rescued pup. She was hand-reared before the
surrogate program began. After she was released into
Monterey Bay, she had to be recaptured because she was
jumping on kayaks and divers.
“We found that with the sea otters, putting them with an
adult female in a fairly shallow pool for six months far
outweighs whatever we were doing trying to raise these
pups.”
Sea otter populations are recovering at a slow pace in
California. But this program is contributing to the
population.
Johnson says the apparent survival rate of the re-released
pups is now about as good as that of newly-weaned pups
in the wild. Some have even successfully raised their own
pups, using skills they picked up from an exhibit otter at
the aquarium.

There are thousands of kinds of frogs and toads that could go extinct
in our lifetime. Rebecca Williams reports zoos are trying to save the
most endangered frogs by playing matchmaker:
“Okay, so we’re in our Panamanian golden frog room.”
This is the frog bachelor pad.
(slow music)
The lights are low. One of the girls
is sitting naked under the waterfall. And in a dark corner of an
aquarium, there’s some action.
“Well, the male has clasped onto the female around the back…”
Danna Schock is like Dr. Ruth for frogs. She’s the curator of frogs
and toads at the Detroit Zoo. Right now she’s trying to get these
little yellow and black frogs in the mood.
“They were just put together a couple days ago, we’re not sure
they’re feeling it yet. I don’t know if we need Barry White music in
here or what.”
(Barry White song)
Getting the mood right matters because frogs are sensitive. The
temperature has to be just right. Sometimes what the male wants is
just not what the female wants.
Danna Schock wants these guys to have lots of babies. That’s because
frogs are in big trouble in the wild. They’re disappearing really,
really fast.
“The extinction going on is really of the scale that happened
at the end of the Cretaceous when the dinosaurs went. But that
extinction happened over a million years. We’re seeing some of this go
down in my lifetime. This is unprecedented.”
As much as half of all amphibian species on Earth could go extinct in
our lifetime. Here’s why. Frogs and toads breathe and drink through
their skin. Those thin skins make them very sensitive to pollution
from farms and industry and whatever we put down the drain. Also, the
places frogs live are being paved over for parking lots and
subdivisions.
Then there’s another really big problem. There’s a disease
sweeping through frogs around the world. It’s called chytrid fungus.
It can kill frogs in just a few weeks.
Kevin Zippel is the program director for Amphibian Ark. It’s kind of
like Noah’s Ark for frogs. It’s a group working with zoos to save the
frogs and toads that are most at risk. Especially the ones dying from
chytrid fungus.
“The only solution for those species that are susceptible is to bring
them into captivity as a stop-gap measure until the day when we do have
a cure for it.”
Zippel says chytrid fungus was first found in the 1930s in the African
clawed frog. That frog was exported around the world for medical
research. And scientists think the disease was spread with it.
Kevin Zippel says they’re scrambling to bring frogs into zoos before
they’re wiped out. He says it’s always much better for frogs to live
in the wild. But he says, for hundreds of frog species, taking them
into zoos is the only way to keep them alive.
The Wyoming toad is one species that’s been saved by zoos. For all
practical purposes, it’s considered extinct in the wild. Zoos around
the country have taken in the toads and gotten them to mate.
(Sound of tanks bubbling)
At the Detroit Zoo there’s a special quarantine room. It’s under lock
and key. We have to disinfect our shoes so we don’t track in bacteria
or other diseases.
Then Danna Schock lets us peek in on her
babies. These Wyoming toadlets are about the size of gumballs.
“These guys are fabulous little creatures. These are not divas.
They’re just such a pleasure to work with, they’re fun, they eat well.
There are just little Buddha bellies on ’em.”
These little Wyoming toads have big lives ahead of them. A lot of sex.
And their babies might get released back to the same place where they
got their name – Wyoming.
The US Fish and Wildlife Service has been releasing toad eggs and
tadpoles in a few protected areas there.
Brian Kelly is with the Service. Last summer, for the first time in 10
years, his team found new Wyoming toad eggs in the wild.
“It’s incredibly encouraging because that’s why we’re doing this, we
want to establish populations that maintain themselves and remain
viable over time.”
Kelly says the toads are still in trouble. Their habitat has to be
protected. And the fatal chytrid fungus is still a major threat. So
zoos will have to fill the gap for a while.
It’s not ideal. It costs a lot to keep frogs at the zoo. There isn’t
enough room in zoos to save every type of frog. And, as Danna Schock at
the Detroit Zoo will tell you, it’s tough to figure out exactly what
the frogs want. But she says she’s not going to give up.
“I’d rather go down flailing in flames. At least we can say we tried.
And there are reasons to be optimistic. We have had successes – and
they’re scattered, and they’re patchy, and we learn from our mistakes all
the time.”
Schock says it would be much better to solve the frogs’ problems in the
first place. She says that means not paving over all the wetlands. It
means not polluting ponds and creeks. And hopefully, finding a cure
for chytrid fungus.

A recent report accuses the federal government of failing to take simple, inexpensive steps that could reduce the risk of live animal imports. Zebra mussels, Asian carp, and pets that get loose, such as Burmese pythons in Florida, hurt native wildlife and can damage the nation’s economy. Lester Graham talked with Peter Jenkins, one of the authors of the report issued by the Defenders of Wildlife. Jenkins says the U.S. Fish and Wildlife Service is one of the agencies that needs to do a better job screening for invasive species:
Peter Jenkins: They’re charged with protecting native species. They’re charged with enforcing the
Endangered Species Act, which is an important part of this issue because these non-
native species threaten our native species, including threatening endangered species in
many cases.
Lester Graham: In the past, the US Fish & Wildlife Service has been accused of being too
slow to act, even when a problem is pointed out. Would the regulation changes you’re
talking about help speed that process?
PJ: Well, Congress would have to agree to commit more resources to the agency…I mean,
there is only one person, believe it or not, only one person whose job is to assess species
to be listed under that law to keep out of the country. Obviously, we need more than one,
we need some qualified professionals working this area. We don’t need millions and
millions of dollars, but we do need a significant increase, probably five or six or up to ten
professional staff looking closely at these imported animals to assess whether we’re
gonna have problems and which ones need to be restricted.
Now, how’s that gonna be paid for? Well, the industries that are bringing these species in
and that want to benefit from the import trade, whether it be pet or live animals or
biomedical testing or zoos or what have you…Those people bringing these species in
clearly should carry some of the cost of what they’re bringing in and in that way, the
taxpayers don’t get burdened too much.
LG: As you’ve mentioned, this is as much an economic problem as it is an environmental
problem. Why haven’t the dollars and sense of this issue really had an impact on the
politics behind making sure that we can restrict this kind of trade?
PJ: Well, that’s a great question and defenders of wildlife did do a white paper on the
economic impact of animal imports trade. The reason is very simple…the people who
benefit do not suffer the cost when these things go wrong. That is to say, the costs are
suffered by the public in terms of disease or invasive species concern or pests, so these
costs are externalized or passed on to the general public and it’s the taxpayers in the end
who wind up having to pay the costs. On the whole, these species that are brought in,
non-native species, are brought in for the pet trade…That’s by far the biggest reason that
species are brought in. That’s basically a luxury item, that’s not an essential item. Those
that benefit from luxury items should bare the cost.
LG: Now, nature seems to eventually cope with many of these exotic species, even the
invasive species to one degree or another and some people would say that this biological
pollution is nearly impossible to prevent so why fight the inevitable?
PJ: Uh, I don’t buy that argument at all. It’s like saying diseases are natural and people are
going to eventually cope with diseases, so why bother trying to prevent diseases? I mean,
we do it because we want to protect certain values. We want to protect our native species,
we want to protect human health, we want to protect the health of our livestock. Of
course we need to be protective and have adequate standards. I mean, we don’t need to be
operating under a law that was written in 1900 just because some people think it’s futile
to try to deal with this issue…We could cope with it.
HOST TAG: Peter Jenkins was one of the authors of a Defenders of Wildlife report calling on the government to do a better job of screening live animal imports. He spoke with The Environment Report’s Lester Graham. The report is available at www.defenders.org.
The Lincoln Park Zoo in Chicago is opening a new exhibit that immerses visitors in African habitat. Although these kinds of exhibits have been around for a while, this is a particularly important one because the Lincoln Park Zoo is one the nation's oldest and most visited zoos.
One of the nation’s oldest and most visited zoos has opened an exhibit that takes visitors on a virtual trip into the jungle and onto the savannah. The goal is to give people a better idea of what kind of habitats animals need and why it’s so important to save those wild places.

One of the nation’s oldest and most visited zoos has opened an exhibit that takes visitors on a
virtual trip into the jungle and onto the savannah. The goal is to give people a better idea of what
kind of habitats animals need and why it’s so important to save those wild places. The Great
Lakes Radio Consortium’s Lester Graham reports on an African Journey that starts in a big city:
The Lincoln Park Zoo in Chicago is almost always a busy place. Three-and-a-half million people
visit it each year. For years, the Lincoln Park Zoo, like many other zoos, displayed its animals in
groups of like animals. Big cats in one area… primates in another… birds in yet another. But a
new exhibit, the Regenstein African Journey, groups animals by geography rather than by
taxonomy.
Kevin Bell is Lincoln Park Zoo’s Director. He says the new exhibit appears to be an African
jungle in some places… and the dry plains in others…
“We gutted the inside of the building and then rebuilt the inside. When we create new exhibits,
it’s artisans that come in and make the artificial trees and the rock-work all look real and paint the
lichens on the rocks and what-not. So, it’s a very complicated long process and a very expensive
one.”
The zoo spent 25-million dollars renovating the building. Now that it’s finished, visitors are
encouraged to suspend disbelief for a moment and visit wild places in Africa.
Monkeys sit in trees overhead. Birds are loose with the people. Pygmy hippos are viewed above
and below the water line. And giraffes roam with antelopes and ostriches. For visitors, it’s a
unique perspective on animal interaction. For the animals… it’s a more natural setting.
Robyn Barbiers is the General Curator at Lincoln Park Zoo. She says it’s not the same as being
loose in the wild, but the habitat created for the captive animals is a little closer to the habitat that
is their natural home.
“So, these exhibits provide the space, the shelter, the hiding spots, the feeding spots, the social
aspects that the visitors like to see and that the animals need.”
Not only are the animals grouped together with other compatible species, but in a controlled way.
Barbiers says animals not so compatible are put near each other.
“We introduced the wild dogs and the wart hogs to their exhibits yesterday – side-by-side.
They’re not in together, but it’s predator and prey. But, these animals were born in captivity.
There was some excitement, but I don’t know if they really recognized each other as predator
and prey.”
The Lincoln Park Zoo’s African Journey is the latest in a trend among zoos called immersion
exhibits. It enriches the animals’ lives and immerses the visitors in the environment to give them
a better idea of how the animals live.
Jane Ballantine is a spokesperson for the American Zoo and Aquarium Association. She says
zoos have always entertained, but more recently, zoos have seen their role as one of educating
people about animals that are threatened by habitat loss.
“We want them to think about those conservation issues and how things are all interconnected,
but while having a good time. We’re not there to lecture. We’re there to show and showcase and
get people to have these experiences and realize ‘Wow! This is what it’s really like and we should
care about this.'”
And the hope of zoos is that these new exhibits will do a better job of that than simply displaying
wild animals in a cage.
Lincoln Park Zoo Director Kevin Bell says this new exhibit was a huge effort toward that goal…
“So, hopefully, by doing these more immersion exhibits, people get a sense of how exactly the
animal relates to its environment, what its needs are and what it’s going to take to save that
species, long term.”
The Lincoln Park Zoo’s African Journey just opened to visitors and admission to the Chicago zoo
is free.
For the Great Lakes Radio Consortium, this is Lester Graham.
Today's zoo exhibits attempt to
immerse visitors in the scene while also
enriching the animals' lives. Some zoos are criticized for emphasizing appearances instead of the animals' well-being.
Zoos across the nation are putting their animals in more natural settings instead of cages. For some zoos, it’s done to make the animals’ lives a little more comfortable. But for others, it’s simply done to draw more people rather than to give the animals a better place to live. The Great Lakes Radio Consortium’s Lester Graham has the details in the first of a two-part series:
This grizzly at the St Louis Zoo
is displayed in an exhibit that mimics its
natural habitat. A whole industry has emerged to
manufacture these exhibits.
At your local zoo – if you can suspend disbelief for a moment – you might find yourself in the middle of a tropical rainforest. Or a dusty African plain, watching the animals in their natural habitat. Of course, those wild settings are merely a façade. Clever construction techniques covering up concrete cages. In the second of a two-part series, the Great Lakes Radio Consortium’s Lester Graham reports… the thought and planning behind the displays can be nearly as intricate as nature itself:
Zoos have helped public health officials
monitor the spread of the West Nile virus. Besides concerns
about human health, zoos are worried about the birds in their care.
Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports:

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But, this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports.
It’s extremely rare that West Nile virus causes severe illness in humans. But it does happen. While most people won’t even realize they’re infected, about one fourth of those infected will exhibit some mild symptoms. However, the virus can cause encephalitis, which is an inflammation of the brain. In very rare cases it can be fatal.
Zoos have been helpful in monitoring the spread of the disease. It was first identified here in the U.S. by the Bronx zoo in the fall of 1999 after crows started dying in the New York area. Since then, zoos across the U-S have kept watch on their birds and animals. In part to protect them and in part to help health officials track the progress of the virus.
Scientists thought the virus would slowly make its way to neighboring states. But, it’s spread much more quickly than expected. It wasn’t supposed to hit states as far west as Illinois and Wisconsin until sometime next year. But it made it even farther west with reports of it in Missouri.
Researchers have learned the virus is carried by birds such as crows, blue jays, hawks and Canada geese. Dominic Travis is a veterinary epidemiologist at the Lincoln Park Zoo in Chicago. He says since West Nile virus infects birds, experts suggested it would spread southward from New York. That’s because many birds, including some infected with the virus would travel south for the winter. Others, though, said it could spread west.
“And, the westward race won. We were fairly surprised that it came past the Michigan and western Ohio area, but we’ve been prepared because we started this surveillance system and started working with the CDC and USDA and everybody last spring for this specific eventuality.”
Travis says zoos across the Midwest started monitoring for West Nile virus this past spring. They worked with local health officials to determine if the disease had spread to birds in the area.
While birds carry the disease, mosquitoes spread it. So, officials at he Lincoln Park Zoo have been trapping mosquitoes and drawing blood from its animals, testing for West Nile virus. They’ve also been working to reduce the chance that animals will be bitten by mosquitoes. Again. Dominic Travis.
“The two strategies are try and limit the mosquito and if you can’t limit the mosquito, limit the contact.”
Most zoos are hesitant to use insecticides to kill the mosquitoes. So, instead, they try to eliminate places where they can breed. Basically, that’s anywhere a puddle of water stands for more than four days. Travis says that helps meet strategy number one, limiting the mosquito.
“So, a) if you don’t have mosquitoes, the risk is fairly low, and b) if you can’t get rid of all your mosquitoes, then you want to stop mosquitoes from biting the animals and so you do things to keep them separate. And those are –depending on the birds, the size, the situation, the zoo– those are keeping them in during mosquito feeding hours or some people have mosquito nets that they’re incorporating and so on and so forth.”
Zoos are especially worried because they’re responsible for some very rare birds, in some cases the last of a species.
At the Saint Louis Zoo, a huge outdoor flight cage and several other outdoor cages make up the zoo’s bird garden. Zookeeper Frank Fischer says outside bird exhibits are at highest risk.
“We’re making sure that, trying to make sure that none of our birds, even the birds in the outside exhibits here in the bird garden don’t contract any of that disease, say, from crows or our blue jays or birds of that type.”
While birds are most at risk of infection, they’re not the only species hit by the virus. In the U.S., as many as a dozen people have died after being bitten by a mosquito carrying West Nile virus. And even more horses have died. People and horses are considered incidental victims. That is, they don’t carry the disease and they don’t spread it. But they can be infected. A veterinarian in southwestern Illinois, Don Van Walleghen, says he’s gotten a lot of calls from worried customers, asking about West Nile virus.
“Basically, they want to know, is it here? Is it a concern for me?”
And because it’s such a recent phenomenon Van Walleghen’s customers have a lot of other questions. They bring in dead birds, wondering if their dog or cat that was playing with the bird might be infected. So far, aside from horses and people, there have been no reports of other animals, livestock or pets, being infected by West Nile virus, or spreading it.
“In humans, if you are a human bitten by a mosquito that had this disease, you could not transmit it to your kids or to anything else. So, at least that limits the disease from even being thought of as any kind of epidemic.”
But it is spreading. Experts hope that weather conditions next year are not good for mosquito production. But even a relatively normal to dry season as this past year was has not seemed to slow the spread of West Nile virus. If next year is wetter, experts say the virus could spread farther and infection rates could rise. That’s why health and agriculture experts are reminding people to work toward reducing the mosquito population next year. They recommend everything from keeping roof gutters unclogged to prevent standing water, to landscaping yards and driveways to eliminate puddles. Anything that will slow mosquito production next year will hopefully slow the spread of the West Nile virus. For the Great Lakes Radio Consortium, this is Lester Graham.
Researchers might soon have a vaccine to protect birds from the West Nile virus. The Great Lakes Radio Consortium’s Lester Graham reports:

Researchers might soon have a vaccine to protect birds from the West Nile virus. The Great Lakes Radio Consortium’s Lester Graham reports.
The centers for disease control and the U.S. Army are getting help to develop a vaccine for prevention of the mosquito borne West Nile virus. Here in the U.S. in the past couple of years, the virus has been responsible for the deaths of thousands of birds from more than seventy species. Michael Hutchins is with the American Zoo and Aquarium Association. He says research into a vaccine ahs been driven by the need to protect birds in zoos.
“The current studies are to develop an injectable vaccine, but the intention is to try to take that and develop an ingestible variety that could be spread on bird feed and would therefore have a hopefully-big impact on wild birds as well.”
Chicago’s Brookfield Zoo, the Walt Disney Foundation, the Wildlife Conservation Society and the American Bird Conservancy have all contributed to the project. Hutchins says a vaccine could be developed as soon as the next month or so. For the Great Lakes Radio Consortium, this is Lester Graham.
