The Cerrado is a type of savanna that occurs in Brazil, Paraguay and Bolivia. It is one of the largest Brazilian biomes and extends from the northeastern coast, through the centre of the country, until the western region. Its original domain represents 21% of the national territory, approximately 2 million km2. The Cerrado has high biodiversity, the climate is hot and there are periods of rain and dry, with occasional spontaneous fires in the dry season. The trees have twisted stems and long roots, allowing the absorption of water – available in the Cerrado below 2 meters deep, even during the dry season and wet winter.
