There are five species of musk deer of the genus Moschus, in China, occurring in about 17 provinces. We estimate the total numbers in China to be between 220,000 and 320,000. In some areas the populations are in decline, and some are close to extinction due to over-hunting and habitat loss or degradation, the former being the primary threat to musk deer populations. To conserve musk deer, in situ protection should be improved, and the present unsustainable forest exploitation in the range areas should be halted. Poaching of musk deer, and smuggling of musk deer products, should be prevented. Domestic use of musk should be restricted. In some areas where musk deer have become extinct or are critically endangered, ex situ protection should be introduced. Musk deer farming should be revised and developed according to biological requirements.
