There are 16 forest reservation areas in Shaanxi Province which contain about 273 Giant Pandas. These areas are isolated from each other by mountains, rivers and man made highways. The pandas within them can not venture to another island, which can cause in-breeding and a higher chance of disease.

The "Shaanxi provincial forest department" have stated that these areas will be connected together by corridors several kilometres wide. They will be formed by planting trees and grasses and building tunnels under highways.
