Snub-nosed monkeys inhabit mountain forests up to elevations of more than 4,000 m (13,000 ft). In the winter, they move into the deeply secluded regions. Higher elevation areas are more remote and difficult for humans to access and utilize and other studies have found less deforestation, more reforestation and afforestation, less range contraction, and less extinction in topographically steep areas.[1] All Rhinopithecus species inhabit primary forest and grid cells with tree cover ≥ 75% might constitute important potential habitat.[1] They spend the majority of their life in the trees.
