Plain of Reeds

Plain of Reeds (in Vietnamese: Đồng Tháp Mười) is an inland wetland in Vietnam's Mekong Delta.

Đồng Tháp Mười is a "back swamp" forming a large inundated depression of highly acidic soil.

It is similar to a very large swampy floodplain stretching along the Bassac River from Châu Đốc to the foot of the Takeo Plateau.

[1][2] Within Đồng Tháp Mười the Tràm Chim National Park has been protected for the conservation of wetland ecosystems.

During the First Indochina War, the swamp frequently served as a base for the communist-led Viet Minh, though the French anticipated and prevented this on at least one occasion.
