A Little History

The tropical Savanna of Brazil is the second largest Biome in South America and represents 23 percent of the country. Another word for this Biome is Cerrado, which came from the Portuguese language meaning dense, closed. The first detailed account of the Brazilian Cerrados was discovered by a Danish botanist named Eugene Warming in 1892. There is little fossil evidence of the geological history but they are suggestions that it existed in the prototypic form in the Cretaceous, which is before the final separation of South American and Africa Continents.  The climate is like your typical savanna it receives 50 to 100cm of rainfall. The arrangement of its great age and dynamic phase in distribution is most likely cause of this rich biodiversity. Seasonal fires also play a vital role in the savannas biodiversity. The tropical Savanna in Brazil is home to 160,00 species including plants animals and fungi. This biome also contains an abundance of forests and rich soil. Although Unlike the African Savannas, Brazil has lost the fauna of large mammals, but now the reintroduction of grazers; the cattle and horses take the place of those faunas and restored the balance of vegetation. In the past Brazilian country people populated the Cerrado. Native vegetation provided resources for houses, seasonal fruits, fiber, firewood and other products. But now recently it hs become connected to modern Brazilian life due to railroads and roads.
