Why are there only four pandas in Foping, Qinling Mountains?

Due to the serious fragmentation of giant panda habitat and low population density in this area, there are only four giant pandas. Foping County is located in the hinterland of the mountains on the southern slope of the middle Qinling Mountains. Most areas are covered by forests. There are towering mountains, dense bamboo forests, pines and cypresses. There are all kinds of birds and animals here. You can smell the flowers at any time, and you can hear all kinds of birds dancing happily and singing sweet unknown songs. Later, for various reasons, a wildlife reserve was established here to protect the giant panda, which provided opportunities for the survival and continuation of species such as giant pandas.
