Đồng Tháp Mười
Đồng Tháp Mười or (also known as the Plain of Reeds) is an inland wetland in Vietnam's Mekong Delta. Most of the wetlands are within Long An Province and Đồng Tháp Province.
==Physical characteristics==
Đồng Tháp Mười is a "back swamp" forming a large inundated depression of highly acidic soil. Until the 1970s, only primitive floating rice could be grown in the area. It is similar to a very large swampy floodplain stretching along the Bassac River from Châu Đốc to the foot of the Takeo Plateau. It was around 1,000,000 hectares in the 18th Century, and is now half that size due to drainage.〔Nola Cooke, Tana Li ''Water Frontier: Commerce and the Chinese in the Lower Mekong Delta'' 2004 Page 37 "Inland Back Swamp — Dong Thap Muoi - The inland Back Swamp probably formed from a shallow sea left ... Around 500,000 hectares now, Dong Thap Muoi was twice that size in the eighteenth century."〕〔''Fragile Lives in Fragile Ecosystems'' Page 740 1995 "The main agroecological zones (Table 1) are strongly acid sulfate soils located in the Plain of Reeds (Dong Thap Muoi), Long Xuyen Quadrangle, and Ca Mau Peninsula, and saline soils form a narrow fringe along the coast.."〕 Within Đồng Tháp Mười the Tràm Chim National Park has been protected for the conservation of wetland ecosystems.〔Magnus Torrell, Albert M. Salamanca, Blake D. Ratner ''Wetlands Management in Vietnam: Issues and Perspectives'' 2003 - Page 75 "The Tram Chim Protected Area was recently recognized by the Government as a national park for the conservation of typical wetland ecosystems in the Dong Thap Muoi area of the Mekong Delta."〕
