TONKIN SNUB-NOSED MONKEY
The total population of this species is believed to be fewer than 250. Recent evidence also suggests that there are only five known locations in Vietnam where these monkeys occur, and these are completely isolated. Although this species is not usually hunted for bush meat due to its "foul taste", it is shot when encountered, and consumed or used in traditional medicine. It has been found in trade in China.
RED RUFFED LEMUR
Confined to parts of Madagascar, the primate is considered critically endangered based on suspected population reduction of at least 80 per cent over 24 years, primarily due to habitat loss and hunting. Measuring 50 to 55cm long, their relatively big size makes them vulnerable to being hunted. Remaining populations in the Masoala Peninsula in Madagascar are also threatened by frequent cyclones. It is estimated that there are 600 of these primates in captivity.
LAC ALAOTRA BAMBOO LEMUR
Conversion of marsh habitat to rice fields has been the most significant threat to this Madagascar species. Locals trap and hunt the wetland lemur with dogs or snares or use sticks to knock them into the water. Conservation efforts have made some headway but it remains critically endangered, with most recent population estimates ranging from 2,500 to 5,000.
Destruction and degradation of habitat as well as hunting for the bush meat trade has reduced their population to small isolated pockets. Based on recent surveys, the primate has not been spotted in any reserves in Western Ghana and may have been eliminated from at least two forest areas in the Ivory Coast, where it used to be found.
NORTHERN BROWN HOWLER
Primary threats to the Brazil native include widespread forest loss and fragmentation due to logging and agriculture. Disease epidemics such as yellow fever could also be decimating this primate. A conservation project is now ongoing.
Deforestation has removed nearly all of the Philippine tarsier's original habitat in many places. It is estimated that 7 per cent of the Philippines remains forested. Another threat to this primate, cited for the first time, is the increased frequency and intensity of typhoons that come with global warming.
