The trees above are Barbatimão (Stryphnodendron adstringens), Family Leguminosae-Mimosoideae. This luxuriant tree in my yard is native to Brazil's cerrado vegetation. The Brazilian cerrado (savanna) bioma covers 2 million km² representing 23% of the area of the country (the same size as Western Europe). It is an ancient biome with rich biodiversity, estimated at 160.000 species of plants, fungi and animals. There are about 800 species of trees and large shrubs in the savanna vegetation. Cerrado is the second largest ecological dominion of Brazil, where a continuous herbaceous stratum is joined to an arboreal stratum, with variable density of woody species. Around 220 species from cerrado are reported as used in the traditional medicine.
In terms of area it is exceeded by only one vegetation formation in Brazil, the Amazonian forest covering approx. 3.5 million km².
Brazilian Biodiversity: approximately two thirds of the biological diversity of the world is found in tropical zones, mainly in developing countries. Brazil is the country with the most biological diversity in the world. It is estimated that we have between 15% to 20% of all the planet's biodiversity. There are 55,000 different native species of plants in Brazil (22% of the world's total), distributed over six major biomes : Amazon (30,000); Cerrado (10,000); Caatinga (4,000); Atlantic rainforest (10,000), Pantanal (10,000) and the subtropical forest (3,000).
