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.
