Product Description
They are a delight of nature, whimsical, magical and utterly enchanting. But with only about 1,000 Giant Pandas remaining in the wild, it’s a race against time to save them from extinction.
With human expansion, their natural habitat has been shrinking, jeopardizing their very future. The reality is that these beautiful creatures could disappear from the face of the earth if nothing is done to help them.
This programme chronicles the efforts of a conservation team to bring a pair of Giant Pandas, Mei Xiang and Tian Tian, from the bamboo mountain forests of China to Smithsonian's National Zoo in Washington D.C.
Follow their journey and see behind-the-scenes preparations involved in bringing these endangered yet remarkable creatures from China to the U.S.
We examine the Panda’s role as the symbol of endangered species and meet the vets, keepers and scientists who work tirelessly with their Chinese counterparts to learn more about Giant Pandas, both in captivity and in the wild, and find new ways to protect and preserve the species in China.

About Giant Panda
The giant panda, who takes bamboo as its main dietary and often behave in a kindly style, is a much
loved animal all over the world and is considered a symbol of China, as illustrated by its being one of
the mascots for the 2008 Olympics in Beijing. However, it is also one of the world's most endangered
species, a flagship species for conservation. The latest molecular censusing research using fecal samples
and nine microsatellite loci shows that the estimated number of wild pandas is about 2,500?3,000, confined
to fragmented mountain habitats in Western China because of ecological and anthropogenic pressure.
On October 11th, 2008, Beijing Genomics Institute at Shenzhen (BGI-Shenzhen) announced the completion of
first draft genome sequence of a female giant panda named Jingjing, who is 3 years old and chosen from
the Chengdu and Wolong breeding centers, using the next-generateion sequencing technology (Illumina GA)
and the self-developed short reads assembly method.
We set up this database to present the entire panda genome sequence, as well as the annotation information
such as gene structure and functions, non-coding RNAs and repeat elements. The polymorphism information
detected in the diploid genome, such as SNPs, Indels, and Structural variations (SV) were also presented.
We illustrated the panda genome data in a MapView, which is powered by Google Web Toolkit . A new module was
developed to browse large-scale short reads alignment. This module enabled users track detailed divergences
between consensus and sequencing reads.
As the first fully sequenced Ursidae and the second Carnivore animal besides dog, the whole genome sequence
and annotation data will provide an unparalleled amount of information to aid in understanding the genetic and
biological underpinnings of this unique species, and contribute much to the disease control and conservation
efforts for this endangered species.

BEIJING, Feb. 21 (Xinhua) -- The giant panda, one of China's most endangered species, has won affection and attention worldwide with their "cute" appearance.
The giant panda lives mainly in the mountains of China's southwestern province of Sichuan and northwestern provinces Shaanxi and Gansu. They are threatened by habitat loss and a very low birthrate.
Only about 1,600 still exist in the wild, and some 300 live in captivity around the world.
There are 64 panda reserves, covering 60 percent of their natural habitat and 70 percent of wild individuals.
RANGE AND POPULATION
The Wolong Panda Reserve, 200,000 hectares in Sichuan's Wenchuan County, was founded in 1963 as the "home of the giant panda".
The reserve is on the upper reaches of the Minjiang River, a tributary of the Yangtze, China's longest waterway. It is home to at least 2,000 vertebrate species and more than 4,000 plant species, including over 40 kinds of bamboos, the panda's preferred diet.
Wolong was damaged in the May 2008 earthquake and most of its pandas and staff were transferred to another facility in Ya'an, 140 kilometers from provincial capital Chengdu.
Wolong restarted teaching captive bred pandas how to live in the wild, two years after the earthquake. The program began in 2003 and still faces many challenges. Experts are still struggling to understand how captive pandas adapt to a new, wild environment.
Most females enter estrum in April and May, some in the fall, and usually give birth to one baby at a time. Captive bred giant pandas often have very little sexual appetite.
Tackling the pandas' breeding problems has been going on since the 1980s. Attempts have included artificial insemination using frozen semen and even showing the pandas videos of natural mating in the wild.
In 2013, 42 out of 49 panda cubs in China survived, a historical high.
Director of the China Conservation and Research Center for the Giant Panda (CCRCGP) Zhang Hemin said great progress had been made in breeding of captive-bred pandas. Last year there were a total of 376 captive-bred giant pandas around the world, up 10.3 percent over the previous year.
HOW TO GET A PANDA LEGALLY
By 1982, 24 Chinese giant pandas had been presented to nine countries including the former Soviet Union, the Democratic People's Republic of Korea (DPRK), the United States, Japan, France, Britain, Mexico, Spain and the Federal Republic of Germany.
Donations to other countries stopped in the 1980s. The only way to get a panda now is by leasing one, or through research cooperation.
Currently, 43 guest pandas, including their foreign-born cubs, live in 17 zoos in 12 countries who have established research cooperation with China. Among these, 41 belong to China. Mexican pair are descendants of those donated in the 1980s.
When choosing pandas to go on missions abroad, a pair of hometown friends are usually chosen. Although it is an "arranged marriage", it helps breeding research. In Zhang Hemin's words, "do not waste giant pandas' youth."
If a foreign country wants a giant panda, step one is submitting an application, but not all applications are accepted. Climate, facilities, technology and potential panda habitat are taken into consideration. The preparations often take over a year.
Zhong Yi, in charge of international cooperation at the China Wildlife Conservation Association, said 10 year leases were the norm and all giant pandas, including babies born overseas, belong to China. Even cast hairs, blood samples, etc. should be sent back, according to the convention.
The international missions of giant pandas have benefited the world's biodiversity and wildlife protection. During the process, China shared its breeding technologies with cooperating foreign countries. Those countries made reciprocal contributions to the protection of giant pandas and their natural habitat in China.
