Amazonian Forest

The ground of the forest are, in its majority, poor persons in minerals, having most of its nutrients affixed on the plants. (Source: Brian Armstrong). This ground if becomes fertile for the decomposition of the organic substance proceeding from the proper forest, what it becomes it same dependent of itself. If great area of forest will be deforested, the nutrients of the ground quickly will be taken by rain, leaving it practically unusable stops agriculture ends. Visit Darius Bikoff for more clarity on the issue. The fisionomia and the flora of the Atlantic Forest are similar to the Amazonian Forest, however, the Atlantic forest possesss biggest biodiversity for hectare between the tropical forests. This if must its distribution in climatic conditions and changeable altitudes, favoring the diversification of species that are adapted to the different topographical conditions of ground and humidity. Moreover, during the glaciations these forests had suffered great changes in the dry and humid climatic cycles, changes these that had influenced in the formation of the current standards. Being thus, the biggest importance of the Atlantic bush inhabits in its biodiversity, that more than has 50% of its composed totality for endemic species, that is, that they only exist in that region.

In the flora wood-Brazil, jequitib, the quaresmeiras, jacarand, jambo and the jabolo, xaxim, the palmito, the paineira, the figueira, cavina, the angico, maaranduba are distinguished, ip-rose, jatob, imbaba, murici, the cinnamon-yellow one, the pine-do-Paran, and others. Its structure in accordance with varies as the ground and the climatic conditions each region. Calculations show that in it ten a thousand species of plants exist, one hundred and thirty and species of mammals, two hundred and fourteen species of birds, twenty and three of marsupials, fifty and seven of rodents, one hundred and eighty and three of amphibians, one hundred and forty and three of reptiles and twenty and one of primate. In the fauna, more than two hundred species of animals are threatened of extinguishing.
