AVALIAÇÃO DA FRAGMENTAÇÃO DA COBERTURA VEGETAL NA BACIA DO RIBEIRÃO JOÃO LEITE, GOIÁS - REGIÃO CENTRO-OESTE

Abstract

The objective of this study was to carry trougha survey of the dispersed native fragments between zone caused by human activies of sub-basin of brook Joâo Leite, state of Goiás ,Brazil. Covering maps had been elaborated, measure of individual areas of fragments divided in section and classes of size of the fraction on hidrografic basin, table, indexes what alow analyze the proprierties of the fraction and prescrible managements from landscape. It follows that: On landscape studied on high and low withoud the zone of the park ecologic Altamiro Moura de Pacheco of sub-basin of brook joâo Leite, the native forest covering is low the required by law. However, the middle section, the zone of native forest is upper that demanded for law, considering one reserve upper 1000 ha, of private, pertaining property farm Santa Branca. Is necessary to stablish practices of handling, after the filling up of the reservoir, thanks to pressure territorial,principally about to amphibians and reptiles what will have the she sweats movement restritive, exposition the predators and preferential losses of habitats, and for the mammals we will have movimentation restricted compromising the increase of the individual due fragmentation of the territory and the alimentary availability. To implement the conection between the fragments is necessary to priorize the corridors of ciliares bushes and to stabilish liaison between the graters fragments.
