Critically Endangered

Location: Indonesia

Pig-tailed Snub-nosed Langurs are found in swamp forests and lowland rainforests of Sumatra, Indonesia (Tenaza 1987, Quinten 2010), as well as in primary forests on the hillsides of the islands‘ interior regions (Tilson 1977); they have also been spotted in habitat mosaics of primary and secondary forest (Paciulli 2004).

This species is listed as Critically Endangered because a population decline of 80-90% over the last 36 years (three generations) is estimated due to heavy hunting pressure and extensive habitat loss (especially on southern islands but quite significant throughout species range).

The Pig-tailed Snub-nosed Langur is threatened mainly by heavy hunting and commercial logging (Whittaker 2006, Quinten et al. 2014).

They are also threatened by the conversion of rainforest into oil palm plantations, as well as forest clearing and product extraction by local people. Sometimes, animals are taken for the pet trade (Whittaker 2006).

The Pig-tailed Snub-nosed Langur is critically endangered on @IUCNredlist vanishing due to #palmoil #deforestation in #Indonesia. Help save this beautiful animal by joining the #Boycott4Wildlife


Conservation efforts for these critically endangered small primates is underway. Read more about Asian Species Action Partnership (ASAP) in Indonesia.
