The Pantanal is one of the largest wetlands, 140.000 km2, in Central West Brazil. It is a sedimentary floodplain influenced by 280.000 km2 of higher watershed. Annual rainfall is 1,000-1,400 mm, very seasonal. There are two main types of mosaic landscapes, according to flood origin: 1) river flood (1-5 m), on clavey eutrophic soils, vegetation being gallery forests, pioneer forests and scrub, Tabebuia and Copernicia parks, seasonal swamps and oxbow lakes; 2) rain flood (10-80 cm), mainly on dystrophic sandy soils (72%) with savanna ("cerrado") grasslands and woodlands, with or without ponds (a few are brackish). Grazing during 200 years of cattle ranching apparently did not cause major changes in the vegetation, except turning tall grass into short swards, as the domestic herd found a nearly empty niche, by scarcity of large native herbivores. However, severe threats originate outside, mainly on the sandy highlands, due to erosion, causing river siltation and consequently changes in hydrology (wet-and-dry to wet), fauna and flora, e.g., killing riparian forest. |
