Ecology
In its natural state, the Plain of Reeds was a seasonal wetland, covered in shallow water for three to six months annually, with annual Wildfire, grass fires in the dry season. Vegetation is thought to have been dominated by ''Melaleuca cajuputi'' trees, grasses, and other grass-like species such as Cyperaceae, sedges and ''Eleocharis''. Human modification of the environment began in the 18th century, with rice cultivation. During the Vietnam War, the area was Herbicidal warfare, drained and vegetation burned for strategic reasons, which had the effect of drying out and Redox, oxidizing the Acid sulfate soil, acid sulfate soils, making them highly acidic and inhospitable. Fires also increased in frequency. Efforts began in 1985 to restore the flooding regime, with success in attracting wildlife. After restoration, species that used to inhabit the area returned, including birds such as the sarus crane and Bengal florican, fish like the giant barb, and grasses like ''Oryza rufipogon.'' The fish provide an important role in feeding the local population.Park history
In 1985, Tram Chim was established by the provincial government as Tram Chim Afforestation and Fishery Company with the goals of planting ''Melaleuca cajuputi'', exploiting aquatic resources, and preserving the Plain of Reeds area. In 1986, the sarus crane was found here. In 1991, Tram Chim became a provincial-level natural reserve to specifically protect the cranes. In 1994, the reserve became a national natural reserve by the decision Circular 4991/KGVX. The protected area covers . In September 1998, the area was adjusted to . In 1998, this area became Tram Chim National Park by the governmental decision 253/1998/QĐ dated December 29, 1998.References
