In the 1970s the population size was estimated at 60,000-80,000 in Mongolia (Dulamtseren 1977). The Institute of Biology of the Mongolian Academy of Science assessed the Mongolian population size in 1986 over 53,000 hectares across 63 units of six provinces, resulting in an estimate of 44,000 individuals. The population size is continuing to decrease: densities fell from six per 5 kmÂ², to one per 5 kmÂ² in one observed population between 1990 and 2000 (Tsendjav and Bujinkhand 2000, Tsendjav 2002). Similar levels of declines due to poaching are believed to have taken place elsewhere within its range. Generation length has been estimated as six years based on data from Nowak (1991). As the causes of this decline, primarily exploitation, is expected to result in a population reduction of at least 30% over the next three generations, Moschus moschiferus
qualifies as Vulnerable under Criterion A3d, and as well as A2d and A4d because of past declines. Further research could show that the species is declining more seriously than has been supposed, and could possible qualify for listing as Endangered.
