Site description Lang Sen is situated in the Mekong Delta region, in the area known as the Plain of Reeds. This area , which was originally dominated by seasonally inundated grasslands, has mostly been converted to agricultural land. Lang Sen was proposed a nature reserve by Long An Provincial People's Committee in 1994. The investment plan proposed establishing a 1,124 ha nature reserve, with the name Dong Thap Muoi. A further 1,723 ha were proposed as a bufferzone. Buckton at al. (1999) mention an area of 3,280 ha (and since the birdcounts given here come from this paper the area is given as 3,280 ha in site details).
Non-bird biodiversity: During a survey of the key wetland sites in the Mekong Delta by BirdLife and the Institute of Ecology and Biological Resources (IEBR), Lang Sen was the only site visited where semi-natural Melaleuca forest occurs along a natural river channel, and, as such is of notable biodiversity value.
