Distribution and conservation status of Lorisinae primates in the middle and lower reaches of Nanxi River in southeastern Yunnan
The Bengal slow loris(Nycticebus bengalensis)and the pygmy loris(Xanthonycticebus intermedius)are two species of Lorisinae primates recorded in China.Their unique ecological and behavioral characteristics highlight the im-portance of research and conservation.However,they are continuously threatened by hunting and habitat loss,resulting in declining populations and shrinking distribution areas.The lack of population and distribution data has hindered the development and implementation of conservation plans.Southeastern Yunnan is a vital region historically known for the presence of Lorisinae primates and the potentially sympatric range of both species.From October 2022 to September 2023,we conducted a detailed assessment of this taxon's distribution and conservation status in Hekou and Maguan counties by interview and transect surveys.We identified nine forest areas with high encounter rates of loris primates.The results showed that this region remains essential for Lorisinae distribution,especially for the pygmy loris.The local communities have a relatively low level of awareness and knowledge about this taxon,which is significantly influenced by education,age,and economic conditions.The distribution areas of loris primates are mainly located on the edges of nature reserves,and current protection approaches seem to be unreliable.It is urgent to strengthen monitoring and man-agement,establish ecological corridors,and raise awareness among local communities through outreach and education programs.
