Python passion: Snake owners tell their story

Posted on February 8, 2010 | 1 Comments

Teenager Elizabeth Bearden says it's hard to explain why she's so fond of the giant Burmese pythons her parents raise at their home in Landon, South Carolina.

She describes how she got to know Daisy, an 18-foot, 230-pound python. "At first, with Daisy, I was scared," she says. "But after a while, it was really fun."

Daisy is one of about 30 Burmese pythons - or "burms," as owners often call them - that the Beardens keep at their home near Charleston. Elizabeth, 13, is fascinated by the giant reptiles.

"They're so sweet," she says. "I don't know how to explain it. They're like a dog to me, pretty much. Except that they don't jump all over you like a dog. They're a lot calmer."

Elizabeth's mother, Theresa, explains that Daisy got her name because she was so graceful and ladylike despite her size.

"She was a very delicate snake, very feminine," Theresa says. "As she got huge, people laughed when they found out her name."

The Beardens have fulltime jobs and breed and sell the snakes as a sideline business. They've named all their pythons. There's Fiona, an albino that Theresa named for her Irish grandparents. Another is named Chodro. And there's X, who got that name because that's what the snake's hiss sounded like to one of Theresa's kindergarten-age daughters.

Elizabeth's fondness for the pythons has pointed her towards a possible career. She wants to study herpetology - the science of reptiles and amphibians - and open a veterinary clinic for exotic animals.

Such passion for giant serpents - or any serpent, for that matter - goes against the instinctive fear of snakes that is deeply embedded in the human psyche. But those who own Burmese pythons and other large, non-venomous constrictors are as fond of their snakes as other pet owners are of their cats and dogs.

"People have a fear of them, and it's understandable," says Chris DeLange, who, with his wife, keeps eight snakes, including a Malaysian python and several boa constrictors at his home in Cedarville, Ohio. They don't show emotion like a dog or cat, and that, in large part, is why people are not fond of them. Unless you're experienced with them, they're very hard to read."

But the snakes are "simple to keep," he says. You feed them every week or two, keep the temperature of their cages regulated, and make sure they have water. The DeLanges's snakes are not as large as the Burmese pythons. His Malaysian python is around seven or eight feet long and his boa constrictor is approaching five feet.

Like Elizabeth Bearden, DeLange also acknowledges the difficulty of explaining why he likes his snakes. "They're really just fascinating," he says. "I get a kick out of holding them, feeling their size and strength. They're very graceful animals. They're just fascinating to watch."

Theresa Bearden says she and her husband keep their pythons in a separate part of their home behind a locked door, and the snakes' cages also are locked. Sometimes visitors to her home are uneasy around the snakes, but many of them eventually warm up to the pythons and even want to touch them.

"I've had friends who have taken two years to eventually touch one," she says. "And I've had friends call and say, 'Can we come over and play with the snakes?'"

Pythons, boa constrictors and similar snakes aren't native to North America. But the business of importing and selling them in the United States is popular and profitable. Their presence has caused some problems, however, especially in the Florida Everglades, where Burmese pythons that escaped or were released into the wild have easily adapted to the warm, subtropical climate and are reproducing.

Estimates of the number of pythons in the Glades vary wildly, from as few as 5,000 to more than 100,000. Because of their size and the absence of any natural predators, the pythons instantly moved to the top of the food chain in the Glades, home to dozens of species of animals not found anywhere else in the U.S. Federal and state wildlife officials fear that the pythons eventually will decimate the unique wildlife in the Everglades.

The U.S. Congress is considering legislation that would prohibit importation of pythons and similar exotic snakes, and also ban interstate transportation of the animals. And while the legislation would not make it illegal to possess the snakes, it would put the snake breeders out of business, DeLange says.

"It would essentially bankrupt the breeders because they'd have to sell only within their own state," DeLange says.

There's also a continuing debate about whether the Everglades pythons are likely to migrate. A U.S. Geological Survey study says pythons eventually could survive as far north as the District of Columbia and as far west as California. But a study by researchers at the City University of New York concluded that pythons couldn't survive outside of Florida.

Theresa Bearden says her family will keep their pythons regardless of whether Congress clamps down on importation and interstate transport of the snakes.

"I can't imagine life without them" she says. "They bring so much into my life. If you could handle them you'd understand them more."

"We could have pristine water quality, and it could be lifeless except for these large predators," Horne said.

Boreal landscapes added to Canada's parks

Posted on February 7, 2010 | 1 Comments

National and provincial parks larger than Yellowstone and Yosemite combined are to be created in the boreal forests of Labrador's Mealy Mountains, Canadian government authorities announced Friday.

Canada's Environment Minister and minister responsible for Parks Canada, Jim Prentice, and Newfoundland and Labrador's Minister of Environment and Conservation, Charlene Johnson, said in a news release that they had agreed to establish a new national park reserve in the Mealy Mountains area of eastern Canada.

The park reserve will protect 4,100 square miles (10,700 square kilometers), which will make it the largest national park in eastern Canada.

The Newfoundland and Labrador Government will establish a waterway provincial park to protect the Eagle River, adjacent to the proposed national park reserve. The waterway park in the river watershed will encompass 1,200 square miles (3,000 square kilometers) of wilderness and include almost the entire length of the Eagle River from the headwaters to the sea.

Together these areas will protect over 5,000 square miles (13,000 square kilometers) of boreal forest.

Consultations with aboriginal groups will continue throughout the national park reserve establishment process, the ministers added. "Traditional land-use activities by Labradorians will be permitted to continue within the national park reserve, managed to emphasize ecological integrity and conservation measures," they said in their statement.

"As we enter into the International Year of Biodiversity, it is fitting that we are working to establish a national park reserve to protect this spectacular boreal landscape for all time, for all Canadians," Prentice said. "This part of Labrador is not only of ecological significance, it is also of great cultural importance and we are committed to moving forward in a way that recognizes and respects the traditional connections people have with the land."

"The Government of Newfoundland and Labrador is pleased to dedicate an area of Labrador rich in natural and cultural heritage to the people of the province, the country, and indeed the world, to protect these special places for all time," Johnson said. "This initiative demonstrates our understanding of the importance of our ecosystems and our commitment to biodiversity conservation."

The ministers unveiled the boundary for the national park reserve along with a conceptual boundary for an adjacent waterway provincial park. They also signed a memorandum of understanding outlining the next steps the two governments will take to establish the national park reserve, including the negotiation of a federal-provincial land transfer agreement.

"These parks in the Mealy Mountains, when established, will protect a stunning array of boreal ecosystems and wildlife, along with landscapes of great cultural significance," Prentice and Johnson said.

Conservation organizations greeted the news of the proposed new parks with loud applause.

"The Mealy Mountains rise dramatically from the shores of Lake Melville in southeastern Labrador. Reaching heights of more than one kilometre above sea level, they are an island of arctic tundra surrounded by boreal forests and coastal seascapes," said Nature Canada, a conservation charity representing 350 naturalist organizations.

"The parks will serve as a large anchor of protected boreal forest, wetland and tundra along the Atlantic Flyway, an important breeding ground and migration route for many arctic bird species heading to wintering grounds in the south--some as far as South America," Nature Canada says on its Web site. "Species breeding in or migrating through the park include peregrine falcon (nationally Threatened), least sandpiper, rusty blackbird (Special Concern), blackpoll warbler, olive-sided flycatcher (provincially Threatened) and Arctic tern.

"The nationally at-risk eastern population of harlequin duck nests along wild rivers throughout the region," said Alex MacDonald, Nature Canada's protected areas campaign manager. "Creating a national park will protect important river ecosystems and limit human activities around nesting sites, which can help this species to rebound throughout its breeding range."

The Mealy Mountain herd of the Threatened boreal forest population of woodland caribou, estimated at just 2,000 remaining, will gain urgently needed protection of its habitat within the national park's boundaries, Nature Canada continued. "Caribou need large areas of undisturbed old growth woodland, as these forests not only provide a necessary food source, but protection from predators such as wolves and bears."

Establishing a national park will also help mitigate the effects of global warming, Nature Canada said. "The soils of the Mealy Mountains region are rich in organic carbon, which makes them an important storehouse for greenhouse gases that can accelerate global climate change. Leaving these soils and extensive wetlands undisturbed will help to reduce potential carbon emissions that could impact climate change."

The federal Mealy Mountains National Park and the provincial Eagle River waterway park will be one of the largest protected areas in eastern North America, about equal in size to the protected lands in New York's Adirondack State Park, the Canadian Boreal Initiative (CBI) said in reaction to the official announcement.

CBI works with governments, conservation organizations, resource companies, aboriginal peoples, and scientists to preserve the Canada's boreal forest. 

The proposed new protected areas are a major step towards completing the Canadian National Park system, and will nearly double the total area protected within the province of Newfoundland and Labrador, CBI said in a statement.

"Labrador's Mealy Mountains region offers exceptional opportunities for tourism, recreation, and exploration of Canada's heritage; continued traditional uses by Aboriginal and local people, and protection of significant areas of habitat for the threatened Mealy Mountains woodland caribou herd," CBI said.

"This protected area covers Labrador's critical wetlands and salmon and brook trout habitat. They provide a haven for a threatened woodland caribou herd, along with moose, black bear, osprey, bald eagles and a species of special concern, the eastern population of the harlequin duck," CBI said.

"This is an outstanding boreal landscape with a rich and diverse ecological and cultural history. These parks represent an exceptional legacy for present and future generations," said Larry Innes, executive director of CBI. "We are very pleased to recognize the achievement of the governments, the aboriginal peoples and local organizations who came together to advance a common vision for the protection of this important region."

The announcement set an important precedent for parks in Canada, Innes continued. "This is not a remote, off-limits park; this is a new approach to conservation, that incorporates traditional uses and celebrates Labrador's rich and diverse cultural heritage, while securing ecological values."

"This is a great leap forward in efforts to complete the Canadian National Park system," said Steve Kallick, director of Pew Environment Group's International Boreal Conservation Campaign, of the announcement to create a Mealy Mountains park reserve.

"These new parks will draw tourists from around the world, conserve lands important to aboriginal Canadians and safeguard the habitat of the Mealy Mountains woodland caribou herd.

"Bigger than the United States' Yellowstone and Yosemite parks combined, the scale of this new protected area is remarkable. It will rival the largest protected areas in eastern North America, equal in size to New York's Adirondack State Park, twice the size of Everglades National Park and six times the size of Great Smoky Mountains National Park," Kallick said.

If you think small, furry rodent-like mammals are unappealing, then you have never met a pika! They look like very small rabbits, are often quite tame, and they are enormously endearing. They are usually stuffing their faces with vegetation.

It's also where they live that makes them so fascinating. If you're watching a pika the odds are you're in lovely scenery, with snow-covered mountains nearby. Pikas generally live in mountains--about 8,000 feet above sea level in most of the continental U.S.

At my age, stopping to watch pikas gives me a chance to catch my breath without younger companions ragging me about being out of shape.

Pikas live in places we often think of as pristine. Yet they have become the poster child for how global warming is harming biodiversity.

That's why yesterday's ruling by the U.S. Fish and Wildlife Service that they are not threatened with extinction is immediately controversial.

There's a lot at stake here--politically, certainly--but there are some important scientific issues too.

Pikas illustrate what we don't know--and urgently need to know--about the distribution of all species of animals and plants that live in mountains worldwide.

The American pika lives from California to New Mexico and north into Canada. Elevation is really important to them. As one goes north, the low annual temperatures that they need occur at progressively lower elevations.

The controversy is all about what happens in the future, as the climate warms. As average temperatures rise, the pika's range may shrink as the animals find lower elevations too hot for them.

[Watch this National Geographic video about pikas.] 

Video by Public Television's Wild Chronicles from National Geographic Mission Programs

How much cooler it is as one climbs into the mountains is well-known. It is, after all, why we visit the West's mountains in summertime. In early August, I'd rather be outdoors in Telluride than in Washington, D.C.

Last year the world's leaders in Copenhagen couldn't agree to keep the planet's average temperature increase to below 2 degrees C above what it is now. For the pikas a two-degree rise in temperature means climbing an extra 400 meters (1,300 feet) higher to keep as cool as they have in the past.

In some areas, there just isn't land that is high enough. In others, there just isn't very much land.

It gets worse: As the range for species that prefer cool temperatures shrinks, it becomes even more fragmented than it is now. Small populations go extinct quickly--especially when they are isolated from other populations that might supply occasional colonists to rescue them.

Several controversies

The Fish and Wildlife Service pika decision sparked several controversies.

First, scientists disagree over how serious are these reductions in ranges.

The Fish and Wildlife Service argued that the temperature projections past the middle of this century are uncertain and that other things besides temperature--specific habitats for example--might matter more to the pikas. They continued that temperatures at the surface of the ground may matter less than temperatures just below ground, where the pikas can hide. And they felt that pikas could probably avoid warmer temperatures during the hottest part of the day.

Dr. Shaye Wolf, of the Center for Biological Diversity, contests all this. "The Service dismissed studies showing that pikas are disappearing due to climate change and studies predicting that they will continue to disappear," she told me. "Instead they argued that pikas will be able to cope with the massive warming to come. If only pikas were so lucky! The Service should have considered climate change impacts to pikas beyond 2050," she said.

I agree. Climate projections show progressively hotter temperatures as the century proceeds. That a species doesn't die out next week isn't room for complacency if they are going to die out next year.

Mad dogs, Englishmen ... and pikas

"The final argument seems particularly specious," Shaye told me, "If pikas could simply avoid the midday sun--I interrupted her with, "they'd join the mad dogs and Englishmen there!"

Pikas are where they are--high up--likely because they can't handle heat. "Moreover, the climate is already getting warmer--and some populations have already become extinct," Shaye pointed out.

NGS-Grant-logo.jpg

National Geographic Grantee, Dr. Rob Guralnick, understands this as well as anyone. "Pikas are going missing on mountain tops," he says. His colleague, Dr. Liesl Peterson, explains: "Unlike other species, they don't shut down in the winter. They have to have a high metabolism to keep them going. Then, in the summer, if there's a hot period, then can't keep themselves cool enough."

I knew that my next call would be to Dr. Scott Loarie, a former student of mine, now at the Carnegie Institution for Science, in California. Scott is a modeler. And he sent me a map.

"Using museum specimens from over 400 sites, I built a computer model of where the pika should live--all the areas colored in reds to blues on the map," he told me.

"It's good, but not perfect," I told him, as I overlaid his map on one from the Nature Serve site that has range maps of all the species of mammals in the Americas.

"Agreed," Scott replied, "the pikas are not on high mountain tops in Arizona--though they might have been in the past."

"The colors are the probability that the pikas will go extinct in this century--red means they will, while blue means they probably won't."

The predicted distribution of the American pika in the U.S. and Dr. Scott Loarie's predictions of the prospect for where the animal might become extinct. (Blue means unlikely, red means very probably.) The approximate present distribution of the species is outlined in yellow. Data from Nature Serve.

"So how did you estimate those probabilities," I asked.

"Well, 97 of those sites have been visited at least twice--and the pikas have become extinct in eight of them. Extinction is already happening!"

"What's important," Scott continued, "is those extinctions in the last decades have happened in exactly the places the model expects--the low, hot sites, mostly in California and Nevada."

If Scott's map is correct, pikas will no longer be charming companions to weary, out-of-breath hikers like me in Nevada, Oregon, and most of California.

There is a wider, political controversy.

Had this species been declared "endangered," it would have become so because of global warming--and our emissions of carbon dioxide that cause warming. Several people have suggested to me that the Fish and Wildlife Service was under pressure not to classify this species as endangered to avoid that issue.

I knew from our work together, that Scott wanted to tell me something else.

"This is a perfect candidate for citizen science. It's an easy-to-identify mammal familiar to every hiker. We need help from everyone who visits these mountains, to record if, and where they see these mammals," he said.

I'm sure the Fish and Wildlife Service would agree. They concluded their finding, "we ask the public to submit to us any new information that becomes available concerning the threats to the pika ... or its habitat at any time."

The ultimate arbiter of the controversies would be more data. If the pikas keep disappearing from progressively higher mountains, the accusatory finger of global change would be impossible to deflect.

It wouldn't be just North America's pika at risk. There are thirty species worldwide--all living in places that we might have thought untrammelled and far from human impact. (I saw my first pika high in the mountains of Afghanistan.)

And it wouldn't just be pikas. Scott and I know from our research that some large fraction of species worldwide--perhaps 20 percent--might live too close to the top of their nearest mountains to survive an increase of 2 degrees C.

How many such species are at risk is uncertain--it depends on our incomplete knowledge of the elevations where species live. That's something than any naturalist with a GPS or even a good, old-fashioned map could tell us.

The scientific community really needs that help.

New measures to conserve and manage sustainably bluefin tuna, elephants, and a wide range of sharks, corals, reptiles, insects and plants have been proposed by governments attending the next world conference of the Convention on the International Trade in Endangered Species of Wild Fauna and Flora (CITES).

Over 40 proposals will be decided on at the conference, in Doha, Qatar, from March 13 to 25, the CITES Secretariat said in a news statement today.

Some governments will propose to lift CITES regulations on some species, underlining the success of CITES in key areas, CITES added.

CITES is an international agreement to which 175 countries adhere voluntarily. States that have agreed to be bound by the convention are known as parties. The agreement is legally binding but cannot be enforced unless each party adopts its own domestic legislation to ensure that CITES is implemented at the national level.

An explanation of how CITES regulates the global trade in wildlife is pasted in at the bottom of this post.

Overfishing, excessive logging

Many of the proposals to be considered in Doha next month reflect growing international concern about the accelerating destruction of the world's marine and forest ecosystems through overfishing and excessive logging, and the potential impacts of climate change on the biological resources of the planet, CITES said today.

"The UN General Assembly has declared 2010 the International Year of Biodiversity and the CITES Conference will be one of the key occasions governments will have this year to take action to protect biodiversity."

Other issues on the agenda include the adoption of urgent measures to:

  • tackle illegal trade in the tiger, rhinos and other species that are on the brink of extinction;
  • address the potential impacts of CITES measures on the livelihoods of the rural poor, who are often on the frontlines of using and managing wildlife;
  • and allocate sufficient financial resources to ensure that CITES goals are fully achieved.

"A substantial budget increase will be necessary to ensure proper implementation of the measures proposed for adoption in Doha, CITES said. The current annual budget of the CITES Secretariat is about U.S.$5 million.

"2010 is a key year for biological diversity. It is the year when the world was supposed to have reversed the rate of loss of our biodiversity---this has not happened," said Achim Steiner, UN Under-Secretary General and Executive Director of the United Nations Environment Programme, which administers the CITES Secretariat.

"The international community must re-engage and renew its efforts to meet this goal. CITES is an important part of this response. By ensuring that the international trade in wildlife is properly regulated, CITES can assist in conserving the planet's wild fauna and flora from overexploitation and thus contribute to the improved, sustainable management of these key natural assets," Steiner said.

"The marine theme of this year's CITES conference is particularly striking," said CITES Secretary-General Willem Wijnstekers. "It confirms a trend that began in 2002. CITES is increasingly seen as a valuable tool to achieve the target of restoring depleted fish stocks by 2015 to levels that can produce the maximum sustainable yield, as agreed at the Johannesburg World Summit on Sustainable Development."

Bluefin tuna and sharks

According to the Food and Agriculture Organization of the United Nations, the world's capture (non-aquaculture) fisheries produced 92 million tonnes of fish in 2006, of which 81.9 million tonnes came from the sea, CITES said in today's statement.

"The value of the total marine and freshwater catch at the first point of sale was around U.S.$91.2 billion. As a result, it is estimated that some 52 percent of marine fish stocks or species groups are fully exploited, 19 percent overexploited and 9 percent depleted or recovering from depletion.

"The maximum wild capture fishing potential from the world's oceans has probably been reached, and a more closely controlled approach to fisheries is required." 

"The maximum wild capture fishing potential from the world's oceans has probably been reached, and a more closely controlled approach to fisheries is required," CITES said.

"A growing number of commercially exploited fish have come under CITES controls in recent years, for example: the basking and whale sharks were included in Appendix II in 2002, the great white shark and the humphead wrasse in 2004, and the European eel and sawfishes in 2007.

"At the forthcoming conference, proposals will be made to bring eight commercially fished species under the purview of CITES."

Monaco is proposing a complete ban on international commercial trade in the bluefin tuna.

"This iconic species can reach 3 meters in length and over 650 kilograms in weight. It can swim at nearly 40 kilometers per hour and dive to 1,000 meters deep," the CITES statement said. "It is highly sought after as a delicacy: in January 2010, a single fish was reportedly sold for over U.S.$120,000.

"Although it has been fished for many centuries, its populations in the Atlantic Ocean and Mediterranean Sea have undergone very substantial declines in the last 40 years. Repeated efforts have been made to ensure more sustainable fishing, but now Monaco claims that it is time to bring the international trade to a halt to allow time for the species to recover."

The scalloped hammerhead shark occurs widely in coastal warm temperate and tropical seas and is exploited extensively for its fins. Significant declines in the population of the species have been reported in many areas where it is caught, CITES said.

"Two other species of hammerhead shark (great hammerhead and smooth hammerhead) and two further sharks (sandbar shark and dusky shark) have similar shaped fins, and the proponents, Palau and the United States, recommend that all these species be subject to CITES trade controls."

whitetip-shark-photo.jpg

Palau and the U.S. are also proposing that trade CITES controls be applied to another shark, the oceanic whitetip, which, in spite of its wide range in tropical and subtropical waters, has declined in numbers wherever it has been harvested for its fins, CITES said.

In total, several million sharks of these two species are estimated to be fished annually to supply the demand for fins.

"The porbeagle shark has equally experienced population declines, notably in the northern Atlantic and the Mediterranean, owing to unsustainable fishing for its high-value meat and fins. Palau and Sweden, on behalf of the European Community, note the lack of consistent data on the global catch of this species. They argues that requiring CITES export permits will ensure that international markets are supplied by fish from sustainably managed fisheries that keep accurate records," CITES said.

The spiny dogfish is a small shark that was once abundant in temperate waters. "It is now overexploited for its meat, which is highly valued in Europe (often sold in 'fish and chips' shops in the British Isles) and elsewhere," CITES said.

Like many other sharks, the spiny dogfish "is particularly vulnerable to excessive fishing because of its slow reproductive rate," CITES said. "It also tends to travel in large schools of hundreds or thousands, which are easier for fishing boats to harvest them in large quantities. Palau and Sweden, on behalf of the European Community, propose listing the spiny dogfish in Appendix II (which manages trade through a permit system) and establishing a sustainable fishery management program for the species."

Corals

The most valuable of all the precious corals, red or pink corals, have been harvested for over 5,000 years and used for jewelry and other decorative items, CITES said. "Their treelike colonies provide protection and habitat for other marine species and occur in the tropical, subtropical and temperate oceans, often at great depths.

"Overharvesting for international trade and the destruction of colonies by bottom trawls and dredges have greatly affected their capacity to reproduce and regenerate.

"The United States and Sweden, on behalf of the European Community, propose adding the red or pink corals to Appendix II to control the trade therein."

Elephants and ivory

The long-running global debate over the African elephant has focused on the benefits that income from ivory sales may bring to conservation and to local communities living side by side with these large and potentially dangerous animals versus concerns that such sales may encourage poaching, CITES said.

"This year's proposals again reflect opposing views on how best to improve the conservation and sustainable use of the world's largest land animal."

"CITES banned the international commercial ivory trade in 1989. In 1997 and 2002, recognizing that some southern African elephant populations were healthy and well managed, it permitted Botswana, Namibia, South Africa and Zimbabwe to sell some stocks of ivory to Japan totaling over 150 tons. The sales took place in 1999 and 2008 and earned some U.S.$20 million for elephant conservation and community development programs within or adjacent to the elephant range.

"At this year's conference, Tanzania and Zambia are seeking similar approval to sell government-owned stocks that have accumulated over the years. Tanzania has nearly 90 tons of such stock, and Zambia just over 21 tons.

"Taking the opposite view, the Congo, Ghana, Kenya, Liberia, Mali, Rwanda and Sierra Leone are proposing a halt to the limited international trade in African elephant ivory currently permitted and a 20-year moratorium on any proposals to relax international trade controls on African elephants."

The potential threat to the polar bear from climate change has been much discussed recently, and the United States is seeking to increase its protection in CITES by completely prohibiting international commercial trade in the species, CITES said.

Mexico and Egypt are seeking to reduce CITES controls on the Morelet's crocodile and the Nile crocodile, respectively, as they believe that the status of these species in the wild has improved.

Honduras and Guatemala are seeking to apply CITES controls to four species of spiny-tailed iguanas that are increasingly sought by hobbyists in other countries.

Bolivia proposes that similar measures be adopted for the spectacular Satanas beetle, which is also sought by collectors.

Madagascar is seeking to include 12 endemic plants in Appendix II, while Brazil and Argentina propose the the same listing for the Brazilian rosewood and the Palo Santo, respectively, two tree species that produce essential oils extensively used in perfumery and cosmetics.

Other proposals call for lifting all trade restrictions on certain species on the grounds that they no longer require such protection. These include the marsh rose and the Swartland sugarbush from South Africa, and the North American bobcat or lynx.

How CITES works

(From information provided by the CITES Secretariat)

Thousands of species of wild fauna and flora are used by people in their daily lives for food, housing, health care, cosmetics or fashion.

CITES recognizes that commercial trade in these plants and animals may be beneficial both to conservation and to the livelihoods of local people.

However, unregulated wildlife trade can seriously affect species populations, especially those that are already vulnerable as a result of other factors, such as habitat loss.

Governments responded to this concern by adopting CITES in 1973 to regulate international wildlife trade and ensure that it remains at a sustainable level. With 175 Parties, CITES remains one of the world's most powerful tools for biodiversity conservation through the regulation of trade in wild fauna and flora.

Even setting aside commercial fishing and the timber industry, international trade in wildlife remains a very lucrative business, estimated to be worth billions of dollars annually and to involve more than 350 million plant and animal specimens every year. Unregulated international trade can push threatened and endangered species over the brink, especially when combined with habitat loss and other pressures.

CITES Appendices

CITES provides three regulatory options in the form of Appendices.

Animals and plants listed in Appendix I are prohibited from international commercial trade except in very special circumstances. Appendix I contains about 530 animal species and a little more than 300 plant species, including all the great apes, various big cats such as cheetahs, the snow leopard and the tiger, numerous birds of prey, cranes and pheasants, all sea turtles, many species of crocodiles, tortoises and snakes, and some cacti and orchids.

Commercial international trade is permitted for species listed in Appendix II, but it is strictly controlled on the basis of CITES permits. This Appendix II covers over 4,460 animal species and 28,000 plant species, including all those primates, cats, cetaceans, parrots, crocodiles and orchids not listed in Appendix I.

Finally, Appendix III includes species that are protected within the borders of a member country. By including a species in Appendix III, a country calls on others to help it regulate trade in the said species by making the issuance of a certificate of origin necessary to enter into trade. This Appendix lists over 290 species.

CITES, then, does much more than regulating trade in large charismatic mammals. It sets up a green certification system for non-detrimental wildlife trade (based on CITES permits and certificates), combats illegal trade and related wildlife offenses, promotes international cooperation, and helps establish management plans so that range States can monitor and manage sustainably CITES-listed species.

CITES requires each member State to adopt the necessary national legislation and to designate a Management Authority that issues permits to trade. Governments must also designate a Scientific Authority to provide scientific advice on imports and exports. These national authorities are responsible for implementing CITES in close cooperation with Customs, wildlife enforcement, police or similar agencies.

As the impact of trade on a population or a species increases or decreases, the species can be added to the CITES Appendices, transferred from one Appendix to another, or removed from them. These decisions are taken at the triennial CITES conferences and must be based on the best biological information available and on an analysis of how different types of protection can affect specific populations.

It is worth noting that when a species is transferred from Appendix I to Appendix II, its protection has not necessarily been 'downgraded'. Rather, it can be a sign of success that a species population has grown to the point where trade may be possible with strict oversight. In addition, by allowing a species to be commercially traded at sustainable levels, an Appendix-II listing can actually improve protection by giving local people a greater incentive to ensure the species' survival.

The CITES Secretariat produces recommendations on the proposals described above after analyzing them against the various listing criteria. These criteria relate to: trade (is the species being actively traded? Is trade really the problem rather than, say, habitat destruction?); biology (what is the scientific evidence that populations are declining or increasing?); and other technical matters (e.g. has the proponent consulted thoroughly other range States?).

U.S.-born pandas take up new lives in China

Posted on February 5, 2010 | 0 Comments

Two giant pandas, Tai Shan and Mei Lan, were safely returned today their ancestral homeland, China, by special "Panda Express" air-freighter, Federal Express said in a news statement.

Star attractions at their respective zoos, the pandas left the United States in style. Farewell events attended by hundreds of wellwishers were held for each of them and they were given police escorts to their custom-equipped aircraft.

They have been sent to China to take part in a breeding program.

Send-off events were held at Hartsfield-Jackson International Airport in Atlanta and Washington, D.C.'s Dulles International Airport yesterday as city officials, zoo representatives and others bid farewell to the pandas before departure from U.S. soil, FedEx said.

The company donated the flight from Atlanta to Chengdu via Washington and worked with Smithsonian's National Zoo and Zoo Atlanta to provide for the safety and comfort of both pandas on board a FedEx Boeing 777. Veterinarians from both zoos accompanied the pandas to China.

FedEx video shows how the Boeing 777 "Panda Express" was decorated with a giant panda decal.

FedEx's "Panda Express" has transported giant pandas in the past, the company said, including Tai Shan's parents Mei Xiang and Tian Tian to Washington in 2000. In 2003 FedEx delivered Ya Ya and Le Le to the Memphis Zoo. (Look at pictures and read our 2003 story: Air Panda: Flying Cargo-Class With a Very Special Delivery.) 

Tai Shan is the first surviving giant panda born at the National Zoo in Washington. He was born to Mei Xiang and Tian Tian on July 9, 2005.

"Under the National Zoo's agreement with the China Wildlife Conservation Association (WCA), the four-and-ahalf-year-old panda will take part in a breeding program at Wolong's Bifengxia Base in Sichuan, China," the zoo said in a statement. The zoo negotiated two extensions with WCA to keep Tai Shan for 30 months beyond the original two-year contract.

Mei Lan was the first giant panda cub born at Zoo Atlanta and the only cub born in the U.S. in 2006. Her parents are Lun Lun and Yang Yang.

"This is a bittersweet moment for the Zoo Atlanta family and for fans around the world, but it's a wonderful moment for giant pandas," said Zoo Atlanta Curator of Mammals Rebecca Snyder. "We're very proud to have shared Mei Lan's life to the point where she can now begin making her own contributions to the world's population of giant pandas."

The pandas are in qaurantine for 30 days before making their public debut to visitors to their new home in China. The parents of Tai Shan and Mei Lan remain at their respective U.S. zoos on 10-year loans from China.
