Lorisidae study in Xuan Lien Nature Reserve

There are two species of Lorises have been confirmed in Vietnam, including the slow loris (Nycticebus bengalensis) and pygmy loris (N. pygmaeus). Moreover, the rapid population decline in recent year pushing them to the brink of extinction. As they are under severe threat both species are protected by national law. The species are also listed as Vulnerable under the IUCN Red List of Threatened Species and Vietnam Red Data Book.

Even though the species are under serious decline in population, they are receiving fewer research interests from scientists and protection efforts than other primates. Therefore very little information about the loris is available. Consequently, very few conservation efforts have been made for the species.

In December 2019, Center for Nature Conservation and Development (CCD) in collaboration with Xuan Lien Nature Reserve conducted a preliminary survey for loris in the reserve. The study aims to collect information to raise fund then to improve protection for the species. Findings from this study confirmed the presence of both pygmy and slow loris in the reserve. The loris found mainly in secondary and mixed woodland-bamboo forests and very little information on their presence in the primary forests. The study also confirmed that the loris is under threat from local community as local villagers are still taking the loris to keep as pets and for food. The reserves have a few efforts to raise awareness of local community on endangered wildlife and loris however, the message hasn’t worked yet.

Continuing its loris conservation effort, CCD will collaborate with Xuan Lien to seek for relevant support to conduct more study efforts for the lorises to support more effective conservation actions for these threatened animals.
CCD is committing a long-term conservation program for Vietnam’s Endangered species of plants and wildlife that are under threatened by poaching and trafficking from its forest and through the country. The program focuses on enhancing research, monitoring and conservation capacity for forest rangers, local communities and stakeholders involved; provide technical support for management authorities, enforcement bodies to implement more effective effort to stop the poaching and end the trafficking of threatened plants and wildlife.
