People who want to watch marine mammals like dolphins often head to
theme parks such as SeaWorld. But after a killer whale at one SeaWorld
killed its trainer last month, critics are calling for a reevaluation
of keeping these huge animals captive. Ann Dornfeld has the story.

In the wild, a killer whale’s world sounds something like this:

[Killer whale calls in British Columbia]

But most people see killer whales in an environment like this:

[Electric guitar at SeaWorld show, chanting of “Shamu! Shamu!
Shamu!”, audience claps in time]

SeaWorld calls all of its performing whales “Shamu.” Millions of
people have visited SeaWorld over the decades to get splashed by
Shamu’s tail and watch trainers leap off the killer whales’ noses. The
trainers hug and kiss the animals between high-flying stunts.

But animal rights activist Will Anderson says there is nothing healthy
about the relationship between captive marine mammals and their
keepers. The waters around Seattle, where he lives, are home to wild
killer whales. Anderson has worked to free captive killer whales for
40 years.

“The relationships they have with their trainers are
nothing less than ‘Well, what else is there to do?’ If you’re starved
for what you innately need – social bonding – you’re gonna settle for
whatever morsel you can get.”

Killer whales are actually huge dolphins, not whales. Anderson says
tanks are no place for animals which roam up to 100 miles each day in
their native waters.

“Their bodies and their minds, and their behaviors,
their needs and their huge size, they are all adapted for the wild.
They are not adapted for tanks.”

At SeaWorld, Julie Scardina is the Animal Ambassador. She handles
public relations for the theme park. She says just because killer
whales can roam 100 miles a day in the wild doesn’t mean they often
do.

“The 100 mile statistic there is actually just a
capability. They have the capability of roaming that far, just like
humans have the capability of walking 20 miles or more per day. We
provide opportunities for exercise, for play, and of course during our
shows they get plenty of exercise.”

Scardina used to train killer whales. She says the tricks show the
public what the animals are capable of. And she says keeping killer
whales in a more naturalistic, aquarium-like environment wouldn’t
serve the animals well.

“I’ve worked with animals for over 30 years. There’s
no way you can convince me that it would be better to let an animal
kind of hang. That’s kind of like saying it’s okay to let a person sit
on the couch if they’d like. You need to provide stimulation, you want
to get them up and moving.”

Scardina says the goal of SeaWorld’s Shamu shows is to encourage
marine conservation.

“Well, certainly our mission is to educate people
about the oceans, to inspire them. And that’s what obviously our hope
is, is by seeing these animals and how incredible they are – I know
that’s how I became inspired when I was a child.”

But in a promotional video for SeaWorld’s main killer whale show,
called “Believe,” SeaWorld employees suggest a different theme… more
conquest than conservation.

“How do we get in the water with the top predator in the ocean, y’know. that kills and eats anything it wants at any time.
I thought for a moment right there, y’know what, this is really crazy
what we do. But we are doing it!”

The video, and the “Believe” show itself, focus on the power of the
human spirit – not the marine environment.

Activists like Will Anderson are calling for theme parks like SeaWorld
to return killer whales to their native waters, protected by huge
enclosures. There is general agreement that captive killer whales
wouldn’t survive if released into the open ocean.

A Bee by Any Other Name

Africanized Honeybees – also known
as killer bees – are moving farther
north. The hybridized bees escaped
from a lab in Brazil in the 1950s.
Mark Brush reports:

These bees have established themselves in a number of states throughout the southern U.S. They spread naturally and they are spread through trade. The bees can hide out in shipping containers. One swarm was found inside the engine compartment of a new car.

Now, despite the nick name “killer bee” – experts say, yes they’ll defend their nest with more gusto – but the killer bee name is just hype.

Gloria DeGrandi-Hoffman is a bee expert with the USDA. She says it’s likely that the bees will keep spreading – but beekeeping is an important line of defense against Africanized honeybees.

“You know, beekeepers, whether they’re small or large, are really the buffer between African bees and the public, because they keep pure European bees.”

DeGrandi-Hoffman says – Africanized or not – bees are still a critical part of our food system because they pollinate so many of our food crops.

The Case of the Disappearing Dolphin

  • A false killer whale, which is actually a type of tropical dolphin, with calf (Photo by Deron Verbeck, courtesy of iamaquatic.com)

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Transcript

Commercial fishing in the oceans of the US has done a lot to reduce
accidentally catching marine mammals such as dolphins. But there are
still problems. Ari Daniel Shapiro reports on concerns about one kind
of tropical dolphin called the false killer whale:

Jim Cook has been a fisherman in Hawaii for 18 years.

“You know, it used to be real simple: catch a fish, sell it, and go
back out and try and catch another one.”

Now he owns a company that operates six fishing vessels. Cook’s
ships catch deep swimming sashimi-grade tuna that ends up in sushi
restaurants across the US. They use a technique called longline fishing.

“We have around 45 miles of mainline to which we attach floaters
and 2200 to 2500 baited hooks.”

“The regulations imposed on the Hawaii longline fishery are
probably the most restrictive regulations on any longline fishery in the
world.”

That’s Bill Robinson. He’s an administrator with the National
Marine Fisheries Service. And these regulations he’s talking about are
meant to reduce bycatch. That means catching marine animals other than
the tuna. As a result of these policies, sea turtle bycatch has dropped
by more than 90-percent and seabird bycatch by 95-percent.

Things are looking up, but now there’s another problem. The numbers of
another kind of animal – the false killer whale – are declining. No one
knows why they’re disappearing. It might be related to longline
fishing, but it’s just not clear.

Robin Baird’s a biologist with Cascadia Research.

“There’s a whole variety of lines of evidence that imply the false
killer whale population around the main Hawaiian islands has declined
dramatically over the last 20 years. And I think it’s clearly the most
serious conservation or management issue for whales and dolphins in
Hawaiian waters today.”

Baird thinks the decline is partly related to fewer numbers of tuna
and other species false killer whales eat. He also suspects that the
false killer whales might be moving farther offshore, where they could
get hooked when trying to eat the tuna caught by the longline fishery.

So the question is: should the National Marine Fisheries Service come up
with even more regulations for the longline fishery in case more false
killer whales move offshore looking for tuna.

Bill Robinson with the Fisheries Service isn’t so sure that they
actually go that far offshore.

“That’s speculation, and it may or may not be true. What we
don’t really know is what the range of each population is.”

So, really, at this point, it’s anyone’s guess why the false killer whale numbers are declining.

The biologist, Robin Baird, is concerned that nothing’s being done.

“Unless something is done to change the factors that are
influencing the population, it probably will continue to decline.”

The environmental group Earthjustice and a coalition of
conservation groups have sued the National Marine Fisheries Service over
failing to develop a plan to protect the false killer whales.

The agency has not responded officially to the lawsuit yet. But Bill
Robinson says an action plan is in the works.

“Hopefully by the fall, we’ll be able to not only appoint the
team, but have the team begin work on a take recovery plan that will
make recommendations to the agency to reduce the incidental take of
false killer whales in the fishery.”

Such a plan might end up costing the commercial fishers money. But
Jim Cook says he’s willing to pay. That’s because false killer whales
pick fish off his lines. They eat the caught tuna before the fishers
can haul them in. That can mean a lot of lost income.

“We would very much welcome any methodology almost
irrespective of cost because we’re suffering quite a bit economically as
it is.”

But the National Marine Fisheries Service first has to find that
methodology.

Hitchhiking Invaders Keep Coming

The recent appearance of a new invasive species shows just how easily an even worse invader could make its way into the Great Lakes. Rebecca Williams reports the invaders are hitching a ride in the ballast water of foreign ships:

The recent appearance of a new invasive species shows just how easily an
even worse invader could make its way into the Great Lakes. Rebecca
Williams reports the invaders are hitching a ride in the ballast water of
foreign ships:


The new shrimp that’s here is called the bloody red mysid. Scientists say
the shrimp eat tiny organisms at the bottom of the food web… and could
compete with fish for food.


Steve Pothoven is a fisheries biologist with the Great Lakes Environmental
Research Lab. He discovered thousands of the shrimp near Lake Michigan.


“They’re originally from the Ponto-Caspian region, which is the Black and
Caspian Seas. The Ponto-Caspian is the same region that zebra mussels,
quaggas mussels are from, gobies, so that’s the region we’ve got a lot of
the more recent well known invaders.”


Scientists have an eye out for another invader from that same region. It’s
called the killer shrimp. It’s known for biting and shredding its victims…
and doesn’t always eat what it kills. Some scientists are worried if it
gets in, the killer shrimp could cause even more devastation to the Great
Lakes food web.

Will Chestnut Trees Make a Comeback?

In the first half of the last century, there were millions of American chestnut trees ranging from the Eastern seaboard to the Upper Midwest.

In the first half of the last century, there were millions of
American chestnut trees ranging from the Eastern seaboard to the Upper
Midwest. Now, there are virtually none because a fungus killed them.
A campaign is being launched to bring back a blight-resistant version of
the chestnut, and it’s being planted here in the Midwest. The Great
Lakes Radio Consortium’s Bill Cohen reports:


Sprouts from diseased chestnut trees don’t get the killer fungus until
they’re 4 inches tall, so researchers like Brian McCarthy of Ohio
University have had plenty of raw material to breed a new version of the
chestnut tree.


“Fifteen-sixteenths pure American chestnut and one-sixteenth Chinese
chestnut. And that one-sixteenth of the genome confers blight resistance.”


Ohio is now planting hundreds of the new seedlings on top of abandoned strip
mines. McCarthy believes they may help reclaim the land.


“It’s not that chestnuts like this kind of soil. It’s that probably that chestnuts can
tolerate this type of soil better than other broadleaf tree species can.”


McCarthy hopes that a century from now, the blight-resistant chestnut
trees will once again be prominent in forests, providing high-quality
lumber and food for wildlife.

City Fights to Save Dying Elms

Dutch elm disease is killing dozens of stately old trees in the Midwest this summer. Many people say they regret losing the beautiful old trees. It changes the way a place looks and feels for years to come. Some people are willing to fight and pay to save the elm trees in one Chicago suburb.

Dutch elm disease is killing dozens of stately old trees in the Great Lakes region this summer. Many people say they regret losing the beautiful old trees. It changes the way a place looks and feels for years to come. Some people are willing to fight and pay to save the elm trees in one Chicago suburb. The Great Lakes Radio Consortium’s Jody Becker reports:


When Hollywood producers come looking for the perfect leafy suburb, they often wind up in Evanston, Illinois. This summer’s Tom Hanks flick “The Road to Perdition” was shot here. Filming almost hit a glitch…when Dreamworks suggested removing an old tree to make way for a driveway, the city balked. The scene was filmed; the tree stayed.


Evanston has dozens of trees at least a century old; and some even older than that.


Today, Evanston residents are even fighting a directive from the state’s Department of Transportation to replace obsolete traffic lights because it might mean uprooting some trees. So Evanston’s city Arborist Paul D’Agostino clearly has a rough job: he’s in charge of cutting down trees in a city of tree huggers.


“I’ve had to console people who were crying and hugging their tree and convince them that we were doing the right thing, that there was no choice in the matter.”


Like a handful of tree studded suburbs around Chicago and dozens of cities around the Great Lakes region, Evanston is experiencing a sad summer as Dutch elm disease claims dozens of trees more than half a century old and up to 70 feet tall.


Already more than one hundred Evanston elms have been found to have the killer fungus, and D’Agostino expects the toll to exceed two hundred. Once infected, a tree quickly begins to die…as the fungus blocks the vascular system that delivers water and nutrients to branches and leaves.


D’Agostino explains, standing near two dying elms in front of the Evanston Police Department…


“Both of these trees are in my estimation probably about 40 years old. These are pretty far along now in showing signs of disease…but the typical symptoms of yellowing and flagging leaves has now progressed to dead leaves and bare branches. We’ve got dying sucker growth along the main trunk which means the disease has spread into the main trunk and into the roots, so there’s no curing this tree at this point. The only way to solve this problem now is to remove the tree so it doesn’t spread to other nearby elms.”


(sound of sawing trees)


So five days a week, three crews of three men each are out on Evanston streets, taking down very old, very tall trees.


(sound of chain saw and crash)


For this relatively affluent, leafy suburb defined by its generous trees, the return of Dutch elm disease brings back bad memories of summers nearly 30 years ago, when hundreds of trees were cut down, destroying the canopies of tree tops that shade many of Evanston’s streets.


Still, there are 27,000 trees on city property in Evanston, and D’Agostino estimates three times that many on private property.


Today the suburb’s green and shade is created by a careful mix of hybrids and hardier trees, including Kentucky coffee, linden, gingko, honey locust and horse chestnut.


And the city is moving ahead with plans to continue replanting with diverse species to avoid future epidemics.


But ever a hotbed of activism, Evanston environmentalists of every stripe are on the case, badgering officials to do more than just identify and remove diseased trees.


Many want the city to inoculate the elms against the fungus.


“I’m a conservative republican, not at all a tree hugger. Al Gore and I would not mix ”


Virginia Mann has successfully organized the 13 other homeowners on her block to foot the bill to inject the elms on their street.


There are nine healthy elms on the block, and Mann and her neighbors have decided to adopt and inject three trees each year, at a cost of about $600 per tree.


“I know they add value to my community, I know they add value to my property, and I
know they keep my cooling costs down and I know there’s nothing I can do to replace them. So if you don’t take care of them, that’s it, they’re gone.”


While prognosis for the inoculated trees is excellent, there are no guarantees.
Dutch elm disease is spread both by beetles who carry the fungus on their hairs, and through root grafts between neighboring trees.


There is no way to protect the trees from root grafts. No one is sure why the disease is back and moving so aggressively.


Some citizens say, though inoculations can’t guarantee saving a tree, with only about 3,000 elms left in Evanston they’d rather try, than accept what the city officials seem to believe is the inevitable demise of the species in their suburb.
“Well, you can see my tree suffered an amputation this year.”


Mimi Peterson’s front porch on Ashland Avenue is shaded by a tall sturdy-looking survivor.


“It’s one of the few elms left on the block. You can also see across the street where we lost a really huge one. We’ve already lost nine trees on the block.”


She is well known in town for raising her voice as an advocate for trees; five years ago she hounded the city into more routine tree trimmings.


Now Peterson’s spearheading a group called TREE…To Rescue Evanston Elms, looking to suburbs like nearby Hinsdale…a place with more elm trees and a more aggressive Dutch elm disease prevention program.


Peterson says she agrees that diseased trees should go…but more needs to be done to protect still healthy elms.


Mostly Peterson’s group wants the city to spend more time and money looking for trees to save rather than trees to cut.
