Van Long Wetland Nature Reserve is located in Gia Vien District, Ninh Binh Province. The Reserve is home of the Delacour's langur which is listed by the IUCN – Primate Specialist Group as a critical  endangered species and on the list of the 25 world's TOP most endangered primate’s species. Due to the community low environmental awareness and low standard of living, the local community has overexploited the Reserve resources for their daily livelihoods, resulting in the biodiversity loss and deforestation. In addition, illegal hunting from local residents and outsiders is also a big problem in the area and a major threat to biodiversity conservation. Although the Province has designated the area as a local nature reserve, there is very limited investment in the Reserve management and protection.
