The giant panda, symbol of bio-diversity conservation,peace and friendship, is the treasure of China and is beloved by people from all over the world. The number of giant pandas in the wild is less than 1,000.They are distributed in Sichuan, Shannxi, and Gansu province, however, more than 80% live in Sichuan province. Therefore, the giant panda is also considered to be nature’s gift to Sichuan province. In Chengdu, there are giant pandas living in Congzhou, Dujiangyan, Dayi, Pengzhou and Qionglai. All visitors at home and abroad enjoy the beauty of giant pandas. They are also deeply concerned with the current status and future of the wild and captive population of these rare and endangered animals.
According to international success and experience with protecting endangered wildlife, both in-situ and ex-situ conservation of the giant panda should be reinforced.The goal and mission of Chengdu Research Base of Giant Panda Breeding is to increase the captive population of giant pandas through assisted breeding and, in the future, to reintroduce giant pandas to the wild to enlarge and rejuvenate the wild population. Improve the genetic diversity of the wild population, and allow this species to coexist with humans. To achieve this goal, the Chengdu Municipal Government established the Chengdu Research Base in March of 1987. This research base is supported by local governments and related departments, as well individuals in foreign countries. With the support and guidance of Ministry of Construction,the Ministry of Forestry and the Chinese Association of Zoological Gardens,the Chengdu Research Base has developed 36.5 hectares during the first and second phases after a decade of construction. The 34781.8m² enclosures provide naturalistic habitats for both giant pandas and red pandas. A research building, modern delivery room and animal hospital, Giant Panda Museum and Service Center have also been established.
The Chengdu Research Base of Giant Panda Breeding, located in northern suburb of Chengdu City, Futou Hill,has become one of the main bases for ex-situ conservation of the giant panda. The Chengdu Research Base is only 10km from downtown Chengdu and can be reached by Panda Road.Many endangered species other than the giant panda and red panda also inhabit the Chengdu Research Base, including the black-necked crane,white stork,white swan,wild goose, mandarin duck and peacock. Many types of bamboo, trees and flowers thrive at the Chengdu Research Base. Ninety species of wild birds belonging to 29 genera also inhabit the artificial ecology vegetation zone containing more than 300 species of plants belonging to 68 genera. The man-made structures of the research base have been designed to blend well with the natural scenery. The Giant Panda Museum in the Chengdu Research Base provides educational information pertaining to the many species of plants and animals native to China.
Many talented and knowledgeable scientists work at the Chengdu Research Base in the most advanced facilities.Scientific ideas and information are exchanged and cooperative research is conducted between the experts at the research base and other scientists in universities and research institutions both in China and abroad. Several great achievements have been made in basic and applied fields of research on endangered species. Approximately fifty projects have been supported by the national, provincial, and municipal Scientific Technology Management Departments.More than forty of them received either national, provincial, and municipal technique invention awards or science and technology awards. Some of these nationallyacclaimed projects include research on establishing the methods of extracting DNA and selecting the DNA fingerprinting probe,specifically the giant panda, research on rearing twins of the giant panda, and the etiology and prevention of hemorrhage enteritis of the giant panda. Applications of these research projects promote the conservation of the giant panda and other wild animals. Since the Chengdu Laboratory of Reproduction and Genetics for Endangered Wildlife was established, many specialists have worked here, particularly in the fields of thebiology of reproduction and conservative genetics and have made many important progresses.
The Chengdu Research Base has made great advancements in the field of assisted reproduction for the giant panda. The characteristics of the reproductive organ of giant panda is that male panda’s penis is so short and female’s vagina is so long relatively that the insemination rate is low. This is one of the courses which make giant panda become scarce. Since the first successful attempt to breed the giant panda in captivity using frozen sperm at the Chengdu Zoo in 1980, 56 cubs from 36 litters have been born at the Chengdu Research Base of Giant Panda Breeding and at the Chengdu Zoo. Now there are 28 giants pandas in the research base from the founding 6 giant pandas. Meimei, a female giant panda known as “Super Mom”,bred nine litters of 11 cubs, seven of which survived to maturity.Her daughter, Qingqing, surpassed her by breeding 10 cubs from six litters, all of whom have survived. Furthermore the third generation of captive giant pandas have been survived in the research base.
The Giant Panda Museum was established in 1993.It is the only museum in the world focusing entirely on the critically endangered giant panda and is designed to initiate public education and improve people conservation aware of the environment and wildlife. In addition to the Giant Panda Museum, a Butterfly and Vertegrate Museum have also been opened recently. These three museums occupy a total area of 4000 square meters, contain 800 photographs and 12,450preserved specimens belonging to 2140 species, including 100 mammalspecies,300 birds,240 reptiles and amphibians,230 fish,1100 butterflies and insects and 100 fossils and models.The museums also house 80 scientific animal books from China and other countries. Furthermore, and data. Visitors can use these centers to obtain knowledge of bio-diversity conservation reproduction, and husbandry of wildlife.
Over 100,000 visitors from more than 50 different countries, including many government officials, have enjoyed the beauty of the Base. They also have a great impact on the environment, design, and scientific achievements of the Base. As a result of these achievements, the Base has received the following awards:1)Global 500 Award by the United Nations Environmental Planning Department;2)China Gold Medal for Scientific Technology of Plants,which is the highest award for environmental protection in China;3)the Excellent National Project for the Comprehensive Improvement of Environment Award.
Pandas are good at climbing trees to escape dangers and enemies, to sun bathe, to play and to mate.
Pandas are accustomed to living near creeks and streams.Because they like drinking waters very much, sometimes they go a long way to quench their thirst.
Pandas have not regular rest sites.Sometimes they select tree hole and cave to rest. Sometimes they rest under big tree and in bamboos.
Unlike bears, pandas do not hibernate even in cold winter, they still feed in snowland.
Pandas can only digest and absorb protein,sugar etc. in bamboo. They have large amount of daily intake.If feeding on bamboo shoots,about 40kg are needed and 150 droppings excreted per day. If feeding on stems,they need 17kg or so and defecate about 120 droppings. If eating leaves and branches, 10-14kg are needed and about 120 dropping defecated per day.
Although the giant panda is carnivors,it lives only on bamboo species have been found to feed on. Only accidentally pandas will pick up carcasses,or grasses and iron. In spring and summer the most favored food is bamboo shoots. In autumn and winter, they like to eat stems, leaves and branches.
When flowers burst into blossom,male and female pandas break the habit of living solitarily to run each other, fall in love and mate. Wedding ceremony is often in the field, sometimes in trees. After mating, male and female pandas depart. Before the baby is coming, mother panda selects old tree hole or cave as her maternity den.In late August or early September, the lovely little baby is born, 1-2cubs in a litter.
Usually are parasites,intestinal blooding, distemper,hemolysis anemia,epilepsy and intestinal obstruction etc.
China has organized two field investigations of broad scale. From 1974 to 1976, China had an investigation of panda’s distributions and number in Sichuan, Shannxi and Gansu. From 1984 to 1986, China cooperating with the WWF tried it once more.
From 1978 to 1992, panda observation stations have been set up in Qionglai Mountain, Min Mountain, Liang Mountain and Qin Mountains. They are “WuYipeng”、“BaiXiongping”、 “DaFengding” and Qin Mountains.
In 1980, China, cooperating with the World Wild Fund used advanced radio tracking methods and undertook a detailed study of panda ecology at “WuYipeng” observation station in Wolong, Qionglai Mountain. Later, they had a comparative study at “TangJiahe”, Min Mountain; Mabian, “DaFengding”, Liang Mountain and Qin Mountains.
From 1981 up till now, there have been four international panda conferences in Nanchong, Berlin, Tokyo and Washington. And also there have been many conferences about panda reproduction, the prevention and cure of diseases. There are also seminar groups on pandas in other academic symposium.Since 1869 over forty panda books have been published and about two thousand scientific papers issued at home and abroad. Over one thousand papers wore published in China and more than seven hundred issued outside China.
