Van Long Ramsar Site is a lagoon surrounding the northernmost final section of the Pu Luong – Cuc Phuong limestone range, a belt of limestone area extending in the Northwest – Southeast direction, from Lai Chau to Ninh Jar. This Ninh Binh limestone area includes the area of the common boundary between Ninh Binh, Hoa Binh and Thanh Hoa provinces. This limestone strip is considered the place where many rich flora and fauna species still exist in Northern Vietnam. This landscape also includes part of the Endemic Bird Area (EBA), Central Lowland. The main terrain of Van Long is inland wetlands and steep limestone areas.
Van Long Ramsar Site is located in a densely populated area and surrounded by intensive agricultural land. Van Long wetland area is a place to store and supply water for daily life and production for local residents. In the past 10 years, ecotourism activities have developed, attracting domestic and foreign tourists and are an important source of revenue for the locality.
Regarding biodiversity resources, according to research results to date, there are 1 species of native fish, 6 species of reptiles, 1 species of bird, 8 species of mammals and 3 species of vascular plants recorded in the Area. Ramsar Van Long is listed in the categories CR, EN and VU according to IUCN (2016). There are also many species assessed in the NT and DD categories. Prominent among these is the population of Delacour’s Langur (about 150-180 individuals) which is considered the only growing population in the entire distribution area of the species (Nadler, T. & Brockman, D. 2014, Nguyen Thi Thu Hien pers. comm.). Among the 54 fish species recorded for Van Long Ramsar Site (Nguyen Lan Hung Son (eds.) 2011), in addition to 7 introduced fish species, there are more than 19 species recorded only in Southern China, Northern Vietnam and Northern Laos. , 4 species are only recorded in the Indo-Burma region, and 5 species are only recorded in East Asia. Among these is the species Acheilognathus polyspinus , which has only been recorded in Vietnam so far (according to Fishbase 2016). In addition, Van Long is home to a rich algae and blue-green algae system with 282 species and subspecies (Vu Trung Tang (eds.) 2004) and more than 60 species of aquatic crustaceans and molluscs (Nguyen Lan Hung Son (eds. .) 2011), not to mention unresearched zooplankton species, are also an important and abundant food source for fish species to grow.
