The giant panda, the creature that has become a symbol of conservation, is facing extinction. The major reason is loss of habitat, which has continued despite the establishment, since 1963 , of 13 panda reserves. Deforestation, mainly carried out by farmers clearing land to make way for fields as they move higher into the mountains, has drastically contracted the mammal’s range. The panda has disappeared from much of central and eastern China, and is now restricted to the eastern flank of the Himalayas in Sichuan and Gansu provinces, and the Qinling Mountains in Shaanxi Province. Fewer than 1,400 of the animals are believed to remain in the wild.
Satellite imagery has shown the seriousness of the situation: almost half of the panda’s habitat has been cut or degraded since 1975. Worse, the surviving panda population has also become fragmented : a combination of satellite imagery and ground surveys reveals panda islands in patches of forest separated by cleared land. The population of these islands, ranging from fewer than ten to more than 50 pandas, has become isolated because the animals are loath to cross open areas. Just putting a road through a panda habitat may be enough to split a population in two.
The extremely small size of the panda population worries conservationists. The smallest groups have too few animals to be viable, and will inevitably die out. The larger populations may be viable in the short term, but will be susceptible to genetic defects as a result of inbreeding.
In these circumstances, a more traditional threat to pandas—the cycle of flowering and subsequent withering of the bamboo that is their staple food—can become literally species-threatening. The flowerings prompt pandas to move from one area to another, thus preventing inbreeding in otherwise sedentary populations. In panda islands, however, bamboo growth could prove catastrophic because the pandas are unable to emigrate.
The latest conservation management plan for the panda, prepared by China’s Ministry of Forestry and the World Wide Fund for Nature, aims primarily to maintain panda habitats and to ensure that populations are connected wherever possible. The plan will change some existing reserve boundaries, establish 14 new reserves and protect or replant corridors of forest between panda islands. Other measures include better control of poaching, which remains a problem despite strict laws, as panda skins fetch high prices: decreasing the degradation of habitats outside reserves: and reforestation.
The plan is ambitious. Implementation will be expensive—56. 6 million Yuan (US $12. 5 million) will be needed for the development of the panda reserves—and will require participation by individuals ranging from villagers to government officials.
