Francois' Langur

The species is distributed from Southwestern China to northeastern Vietnam. Before 1990, Francois' Langur could be found in 23 different countries with a total population size of 2,000-2,500 individuals.[5] There has been a dramatic decline in the population size by approximately 85% since then, making this species that of very high priority to potential extinction.[5] The total number of wild individuals is unknown, but there are believed to be less than 500 left in Vietnam and 1,400-1,650 in China.[2] There are only about 60 langurs in captivity in North American zoos.
