Trang An Scenic Landscape Complex Management Board and Cuc Phuong National Park and other partners successfully relocated one male and two females from the Endangered Primate Rescue Centre to their new home in Trang An in August 2020.

Initially, the three langurs were placed in a controlled habitat to gradually adjust to their new environment. They were carefully cared for and closely monitored by a team specially trained by experts from Cuc Phuong National Park.
By October 2020, the langurs were released into the wild on Ngoc Mountain, where they began foraging independently and fully adapting to their natural habitat. Around a year later, the family had its first newborn weighing roughly 300 grammes.
According to a Trang An Scenic Landscape Complex Management Board representative, the birth of the first Delacour langur on Ngoc Island marks a good signal for biodiversity conservation within this unique ecosystem. It lays the foundation for rebuilding a population of one of the world’s rarest and most endangered primates.

Ngoc Island, nestled within the core zone of the Trang An World Heritage site, serves as a safe and isolated habitat for Delacour’s langurs. The area is protected and free from human disturbance, pollution, poaching, land encroachment, and limestone mining. However, external pressures such as weather extremes, disease, and limited natural food sources pose challenges to the conservation of Delacour’s langurs.
Vietnam is home to fewer than 300 Delacour’s langurs, with more than 200 in Van Long Wetland Reserve in Ninh Binh Province and the remainder in Kim Bang District in Ha Nam Province.
