Asian elephants currently only distributed in the Southern Rolling River in Xishuangbanna two protected areas, and not the number, of our country, this is an extremely valuable asset. South River Protection Area Roller remaining two populations, about 15 or so. Here the elephants not only individual is limited in quantity, low population density, age, sex ratio imbalance in the population structure. Plus the small size of protected areas, ecological balance is poor. Therefore, the protected areas elephants facing the danger of extinction of recession.
