Giant Panda consumes a diet low in nutrition

The Giant Panda is a bear native to central-western and south western China.It is easily recognized by its large, distinctive black patches around the eyes, over the ears, and across its round body. Though it belongs to the order Carnivora, the Giant Panda's diet is 99% bamboo.The Giant Panda lives in a few mountain ranges in central China, mainly in Sichuan province, but also in the Shaanxi and Gansu provinces. Due to farming, deforestation, and other development, the Giant Panda has been driven out of the lowland areas where it once lived.

Behavior

In the wild, the Giant Panda is a terrestrial animal and primarily spends its life roaming and feeding in the bamboo forests of the Qinling Mountains and in the hilly Sichuan Province.Pandas communicate through vocalization and scent marking such as clawing trees or spraying urine.The Giant Panda is able to climb and take shelter in hollow trees or rock crevices but does not establish permanent dens. For this reason, pandas do not hibernate, which is similar to other subtropical mammals, and will instead move to elevations with warmer temperatures.Pandas rely primarily on spatial memory rather than visual memory.

Diet

Despite its taxonomic classification as a carnivore, the Giant Panda has a diet that is primarily herbivorous, which consists almost exclusively of bamboo. However, the Giant Panda still has the digestive system of a carnivore, as well as carnivore-specific genes,and thus derives little energy and little protein from consumption of bamboo.The average Giant Panda eats as much as 9 to 14 kg of bamboo shoots a day. Because the Giant Panda consumes a diet low in nutrition, it is important for it to keep its digestive tract full. The limited energy input imposed on it by its diet has affected the panda's behavior. The Giant Panda tends to limit its social interactions and avoids steeply sloping terrain in order to limit its energy expenditures.Twenty-five species of bamboo are eaten by pandas in the wild, such as Fargesia dracocephala and Fargesia rufa.Only a few bamboo species are widespread at the high altitudes pandas now inhabit. Bamboo leaves contain the highest protein levels; stems have less.

Panda diplomacy

Loans of Giant Pandas to American and Japanese zoos formed an important part of the diplomacy of the People's Republic of China in the 1970s, as it marked some of the first cultural exchanges between the People's Republic and the West. This practice has been termed "Panda Diplomacy".By 1984, however, pandas were no longer used as agents of diplomacy.The standard loan terms include a fee of up to US$1,000,000 per year and a provision that any cubs born during the loan are the property of the People's Republic of China. Since 1998, due to a WWF lawsuit, the United States Fish and Wildlife Service only allows a U.S. zoo to import a panda if the zoo can ensure that China will channel more than half of its loan fee into conservation efforts for the Giant Panda and its habitat.
