Ailuropoda melanoleuca (David, 1869)
THREATS
The main threats to the Giant Panda are habitat destruction and poaching. Young animals are caught for zoos, and adults are killed for their pelts which are used to make coats and sleeping mats. These mats are claimed to allow the sleeper to predict the future, and to keep away ghosts.6 Although capital punishment has been introduced for poachers, illegal hunting continues. A single Giant Panda pelt can sell for US $100,000 on the black market.3 Panda meat is unpalatable and hence little subsistence hunting occurs. Many hunters set snares for deer and other animals, especially Musk Deer, and at least one incidental Giant Panda death has been documented.6 Although illegal, such snaring occurs inside as well as outside the reserve system.
Available Giant Panda habitat has been severely reduced by logging and forest clearance for agricultural settlement. In the Sichuan Province, where the majority of Giant Pandas live, satellite mapping and surveys completed in 1974/5 and 1985/8 revealed that the area of habitat occupied by pandas had been reduced from over 20,000 km2 to only 10,000 km2; a similar rate of decline exists in Gansu and Shaanxi.5
During the late eighties, pandas suffered high mortality due to the flowering, seeding and die-back of bamboo over wide areas. This is a natural phenomenon, which may happen every 30 to 80 years, but its effects are exacerbated by the restrictions that increased human settlement have placed on Panda movements. Giant Pandas are now unable to disperse to other areas of suitable habitat in times of food shortage, and many have died of starvation. In the Wanglang Reserve, a population estimated at 196 individuals in 1969 had been reduced to only 10-20 by 1980 because of lack of food.5 Bamboo die-off may however have been an important feature of the species' population dynamics, with enforced emigration promoting out-breeding and maintenance of a healthy population. The small, isolated populations of Giant Panda which remain may be threatened by in-breeding, which is liable to reduce reproduction rate, fertility and survival of young.7
