province. The elevation of the distribution range of the gray snub-nosed monkey is between 500 – 800 m in winters and 1,400 - 2,200 in summers. In winters, the 20 or so groups gather to form three large groups and split back into the original smaller groups in summers. The adult males average 637 mm to 690 mm in size, excluding the tail, which averages 846 to 905 mm. Females are smaller than males.

Though legally protected, the gray snub-nosed monkey is threatened seriously due to habitat loss. The Fanjing Mountains Natural Reserve in Wuling Mountains in Guizhou province that covers the entire distribution range of the gray snub-nosed monkey was not established until 1978, and due to centuries long mining activities that depleted the forest on the northern slope of the mountains, the reforestation effort that last until today is still unable to restore the forest to the level of sustaining the ideal survival enironment for the monkeys.
