Deforestation in the Brazilian Amazon and its Causes Deforestation is the removal of a forest or stand of trees where the land is thereafter converted to a non rural use. Examples of deforestation consist of conversion of forestland to farms‚ ranches‚ or urban use. Between May 2000 and August 2006‚ Brazil lost nearly 150‚000 square kilometres of forest—an area bigger than Greece—and since 1970‚ more than 600‚000 square kilometres of the Amazon rainforest has been ruined. In quite a lot of tropical

The species richness is when we talk about the actual number of species in a community. For example‚ if you go to a bottom ground forest you might see only sugar maple. Therefore‚ the species richness is only 1. Shannon Index measures species diversity too‚ but takes into account species evenness. Species evenness is when the relative abundance of the species in that community are more similar to each other. So by knowing that you have more similar species‚ this allows you to more accurately determine

to wildlife‚ whether they’re rich tropical forests‚ mangroves‚ swamps‚ coral reefs‚ or your own local grassland or woods. Most wild plants and animals are so closely adapted to their own particular habitat that they become rare or endangered if it is damaged or removed. Globally‚ the most worrying losses of habitat are the tropical rain forests‚ because these contain‚ by far‚ the largest number of species. Although large areas of tropical rain forests still survive‚ they are still being lost at
