Conclusions
• In Kon Cha Rang Nature Reserve, and Kon Ka Kinh National Park only the grey-shanked doucs
are confirmed. There is no evidence or information of the occurrence of other douc species.
• The population of the grey-shanked doucs in Kon Cha Rang, Kon Ka Kinh and buffer zone
areas comprises at least 139 individuals and is one of the largest grey-shanked douc
populations. The main habitat of the species is primary and secondary evergreen mountain
forest (900 m-1,300 m asl.).
• The population is genetically very closely related to the population in Ba To District, Quang
Ngai Province.
• Main threats to the species are hunting, logging and wildlife trade. Hunting is the greatest threat
and the doucs are still used for food by the Ba Na minority. Doucs are also used for the
production of traditional medicine the “monkey balm”. Logging activities have a high impact to
the habitat to the forest in the buffer zones and to the corridor area between the two protected
areas.
• A forest corridor between Kon Ka Kinh National Park and Kon Cha Rang Nature Reserve area is of
extreme importance for the conservation of a sustainable population of the grey-shanked doucs.
