Tay ninh: Recent findings from a survey of black-shanked douc langur (Pygathrix nigripes) groups on Ba Den Mountain in the southern province of Tay Ninh have provided an important scientific basis for developing a long-term conservation strategy for the critically endangered primate. The International Union for Conservation of Nature (IUCN)'s 2025 Red List classified the black-shanked douc as critically endangered while Vietnam's Red Data Book 2024 lists it as endangered. It is also included in Group IB - endangered, precious and rare forest animals subject to Vietnam's strict protection.

According to Vietnam News Agency, the survey results highlight the urgent need to implement conservation measures to protect the species' habitat and ensure their survival. Conservationists and local authorities are urged to collaborate and develop strategies that include habitat restoration, anti-poaching measures, and community awareness programs to safeguard this critically endangered primate. These actions are deemed vital as the black-shanked douc langur continues to face threats from habitat loss, hunting, and other human activities.
