pantanal

(pəntənäl`), lowland region of SW Mato Grosso state, Brazil, bordering the Paraguay River and extending to the the western edge of the Brazilian Plateau. Parts of the pantanal extend into Bolivia and Paraguay. It is the world's largest wetland area, c.77,000 sq mi (200,000 sq km). Although subject to annual flooding, it is not a marshland; the water is not stagnant, and there is no malaria. The pantanal completely dries out at the end of the six-month rainy season, leaving lush grasslands that are used for cattle grazing. Millions of migratory birds visit the area every year and over 100 species of mammals and reptiles live there. However, the pristine nature of the pantanal is threatened by encroaching ranching and agriculture, poaching, and coal mining.

Pantanal

 

a swampy area in Brazil located along the upper Paraguay River. It is situated in a tectonic basin near the western base of the Brazilian Highlands. During the rainy season the area becomes flooded, restraining the freshets of the Paraguay River downstream. In dry periods it is a combination of swamps, lakes, and salt marshes alternating with areas covered with forest, shrub, and grass.

The low slope in the Pantanal region makes it difficult to drain the water and, in combination with the meso relief, is possible to observe differents and characteristic environments, associated with the mosaic vegetation, such as the "mountain ranges", with denser tree vegetation, or riparian vegetation, which is very dynamic, due to the sinuous and unstable fluvial beds (Pott & Pott, 2005).
