The Tonkin snub-nosed monkey (Rhinopithecus avunculus) is listed as critically endangered and has been included on each of IUCN/SSC Primate Specialist Group’s top 25 most endangered primates of the world list. The most recent population estimate for this species is 122-224 and it is presently known only from five locations. The largest and best protected subpopulation is that of Khau Ca forest in the newly established Tonkin Snub-nosed Monkey Species and Habitat Conservation Area of Ha Giang Province, Vietnam. Our most recent surveys have confirmed 92 individuals here and we estimate that there may be as many as 100 in the Khau Ca forest. Ongoing activities include population monitoring, study of positional behavior and habitat use, community-based conservation awareness raising, and developing and implementing biodiversity conservation education programs for local elementary school pupils. Due in large part to our continuing presence at Khau Ca this is the only subpopulation of Tonkin snub-nosed monkeys that appears to be increasing in size. Further, unlike the other areas where this species is still found illegal activities including hunting and timber removal are extremely rare in the Tonkin Snub-nosed Monkey Species and Habitat Conservation Area.
