Pandas originally lived in the forest, but they now occupy mountainous terrain in central China, usually at 5,000 to 10,000 feet above sea level. They inhabit broadleaf forests with dense vegetation and plenty of available bamboo.
Pandas inhabit wet terrain where bamboo grows most readily. Since approximately 99 percent of a panda's diet consists of bamboo, they require this growth for survival. Pandas also eat grass, but they occasionally turn to small animals for sustenance. Since pandas suffer from depleted populations due to deforestation and other human-centered threats, several reserves have been established in China to help them repopulate. In captivity, pandas' diets expand to include certain fruits, grains and vegetables.
