Environmentalists have wanted to
“Save the Whales” for decades. But experts
say that can’t happen until the people
realize whales don’t know if they’re in
American waters, Mexican waters or Japanese
waters. Nancy Greenleese reports whales
cannot be saved until all countries protect
them:

Whales travel off many countries’ coasts and different countries have different laws
about protecting the animals. Chris Butler Stroud is with the Whale and Dolphin
Conservation Society. He told a United Nation’s conference for the Convention on
Migratory Species that international cooperation is key.

“When countries try to take political action to conserve an animal, they often think of
their own borders. Not remembering that animals are able to move beyond those because
they don’t see the lines in the sand or lines in the water.”

(sound of Gray Whales splashing)

Gray whales swarm around fishing boats off Mexico’s Baja California peninsula.
They’ve traveled -without passports – from the Bering Strait in Russia, into U.S. waters,
through Canada, and back into the U.S. before arriving in Mexico. Here they’re
breeding, and providing a water show to rival Sea World for ecotourists.

“Oh…it’s the baby. Right there! Right next to us. And here comes mom! (Splash) Hey,
wow, right at us.”

There’s an international agreement that bans commercial hunting for gray whales. And
the whales draw tourists. That’s pretty important for a poor country such as Mexico.

The whales are safe here, but not everywhere.

And everywhere the whales travel and threat looms: climate change. Many whale species
migrate to the poles where the ice is disappearing. The World Wildlife Fund predicts
30% of the ice will melt away in the next 30 years unless action is taken.

Wendy Elliot says that means the whales will have to travel even farther to get to the ice
and the food they find there.

“So they’re already hungry, tired, they’ve traveled a long, long way and now they are
going to have 500 km extra to go. So how these species are going to adapt is very
unclear and it’s very concerning.”

Another worry is the growing acidity of sea water. Greenhouse gases from burning fossil
fuels mix with the water and make carbonic acid in the ocean. Monterey Bay Aquarium
Research Institute chemists have determined that the altered chemistry will increase the
distances that underwater sounds travel. That disturbs the communications of marine
mammals. The oceans and seas are becoming a headbangers’ ball from rumbling ships,
air guns used for oil and gas exploration and military sonars.

Nicolas Entrup, managing director for the Whale and Dolphin Conservation Society,
lobbied at the UN meeting for an international resolution on marine noise pollution.

“Look, we stressed to the governments that underwater noise is a key threat to whales and
dolphins in the ocean. These animals are acoustic animals.”

The Whale and Dolphin Conservation society says research shows loud underwater
noises causes some whales to beach themselves.

At the UN conference, nations passed watered-down resolution to reduce ship sounds.
They did nothing about the noises made by oil and gas industry and the military. Entrup
is furious.

What we’ve passed is absolutely not enough. And I have to say it’s giving in to the
interests of the military and the industries in that occasion. That’s really bad.”

Officials admit that industrial noise can be reduced but the military, that’s another matter.

The 85 governments at the U.N. conference did agree to provide addition protection for
some small whales. But putting any initiatives into effect will be difficult. The global
financial crisis has drastically limited countries’ contributions to field research on whales
and other migratory species. Entrup with the Whale and Dolphin Conservation Society
says the nations of the world cannot ignore the problems.

“If you care, then start now and do not wait until it’s too late. That’s expensive, that’s
irrational, that’s stupid.”

Wildlife groups say rich countries have to reach across borders and give a hand to poorer
countries if we’re going to save the whales.

A new survey shows that at least
one fourth of the world’s wild mammal
species are at risk of extinction. Julie
Grant reports that scientists find human
activities are largely to blame:

The mammal survey took five years, and 1,700 experts in
130 countries to complete. Their results are just being
published in the journal Science.

Jan Schipper of Conservation International is a lead author.
He says the assessment paints a bleak picture.

“It was in fact surprising to find out that 25% of all mammals,
to which we currently have sufficient information, are
threatened with extinction, meaning they are either critically
endangered, endangered, or vulnerable.”

Schipper says hotbeds for extinctions are in Southeast Asia,
Africa and Central and South America – and it is largely
driven by consumers.

For example, if we demand bananas in the middle of winter,
it drives growers to cut down native forests for banana
plantations – but without those native forests, many
mammals are left without a place to live.

Owls Crossing Border Into U.S. For Food

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.

Invasive Fish Rears Ugly Head in Great Lakes

  • With its ability to breathe out of water and wriggle its way over land during dry spells, the media has dubbed the northern snakehead "Frankenfish." Its appearance in Lake Michigan is scary to scientists. (Photo courtesy of USGS)

A few weeks ago, a Chicago fisherman caused a stir when he found a northern snakehead fish. The find set off a frantic search to find out if yet another invasive species is threatening the Great Lakes. The Great Lakes Radio Consortium’s Jenny Lawton has this report:


Just before Halloween, the so-called Frankenfish reared its ugly head… filled with sharp teeth… in Chicago’s Burnham Harbor on Lake Michigan. And it’s still a mystery as to just how it got there.


Although the snakehead is arare item in some Asian cuisines, there’s a more common suspicion amongst local experts and hobbyists. That snakehead was probably a pet that outgrew its tank, and instead of the traditional farewell down the toilet, it was set free in Lake Michigan. Free to eat through the Lake’s food web.


Local pet store manager Edwin Cerna says that’s why he stopped selling the fish years before they were banned by U.S. Fish and Wildlife. He remembers one day, when he was adjusting a tank, he accidentally got in between a snakehead’s lunch and its mouth.


“He bit me in the hand… made me bleed. It hurts. It’s got a nice strong jaw and that’s why it’s so dangerous because it can kill big fish, literally cut them in half. It’s almost like a big old killer whale, like a miniature version of it.”


But why on earth would anybody buy a vicious fish that can grow up to three feet long in the first place? Jim Robinett is with the Shedd Aquarium in Chicago. He says he’s a fish geek.


“I gotta say, as a little fish, when you first buy them, they’re really attractive; they’re neat little animals, but they eat like crazy. They’re voracious.”


Robinett knows not to be fooled by the little guys because what happens next is the perfect plot for a B-horror movie. He says the snakehead fish grows quickly, eventually eating everything in its tank. If it doesn’t die from overgrowing that tank, its owner might be tempted to dump it into a nearby body of water where it will keep eating its way up the food chain. Robinett says that’s the fear in Lake Michigan.


“They could potentially start picking off small salmon and lake trout, which is native to these waters here, they’re not real discriminating, they’ve been known to take things as large as frogs, some small birds, even small mammals that happen to get in the way there close to shore. They’ll eat anything they get their mouth on.”


Most hobby fish don’t last long in Chicago’s cold water. But the northern snakehead is different. The snakehead is native to northern Asia, and the Lake Michigan Federation’s Cameron Davis says that makes the fish feel right at home around here.


“It’s a lot like us Midwesterners, it just kind of hunkers down and… that’s part of the problem with the snakehead is that it can live under very extreme conditions. Which means it’ll out compete those other fish, and that’s a tremendous problem.”


Snakeheads have another edge on other species. The fish guard their eggs, giving their young a better chance of reaching maturity. But perhaps the most peculiar thing about snakeheads is that they can breathe. In addition to its gills, they have an organ that works like a lung and allows it to breathe air. It’s able to live up to three days as it uses its fins to wriggle across land in search of another body of water.


But looking down into the murky waters at Burnham Harbor, Davis says we shouldn’t run screaming yet. It’s not exactly a horror film scenario.


“I don’t think that the snakehead is going to come and grab our children out of schools and eat them or anything like that. But it is a problem for those of us who like to fish for yellow perch and whitefish and some of the things that make the Great Lakes so fantatstic, could really be threatened by this fish getting into Lake Michigan.”


Other invasive species cause an estimated 137-billion dollars of losses and damages in U.S. waterways each year. Cameron Davis says simply banning the local sale of fish like snakeheads hasn’t been enough to keep the Great Lakes safe.


“We’ve got to stop imports of these kinds of fish into the United States. We can’t protect the Great Lakes unless we’re checking these things at the door when they come into the country. It’s that simple.”


Davis is pushing for the passage of the National Aquatic Invasive Species Act. The bill would allocate a total of 174-million dollars to develop new technology for identifying and eliminating the invaders if and when they arrive.


So far, local authorities ahven’t found another snakehead near the banks of Lake Michigan, but Cameron Davis says the initial find just proves how hard it is to regulate what comes into the country’s largest body of fresh water.


Standing on the dock at Burnham Harbor, Davis looks out over the dark waters and shakes his head.


“It’s just an indicator that we’re in a race against time right now. Let’s hope that if there are more than one out there, that they haven’t hooked up.”


If they have, he says, it could truly be the stuff horror movies are made of… at least, for the other fish in the Great Lakes.
