Moreover, the great doubt arising from the misunderstanding of ecological process involved in a tropical rain forests and the pressing need to preserve them, not only as stock for biodiversity but as a main factor in the regulation of global climate, makes southeamerican savannas to be an important alternative for scientific research and mankind use, all under the tendency of a better resource development and its sustainability.
