Foram obtidas uma série de imagens temporais que permitiram avaliar os tipos de vegetação predominante, sua extensão e quais os efeitos que a ação antrópica na região esta causando sobre este maciço florestal. Os resultados indicam que a região é coberta predominantemente por Cerrado Lato sensu e Florestas, Decidual Submontana e Semidecidual, cobrindo em 1966, 1799.091,63 ha e em 2007, 1693.797,40 ha. Durante o período avaliado, perdeu 10,19% de sua cobertura vegetal, substituída por áreas de pastagens e culturas agrícolas.

An amount of time series images were obtained which permitted to evaluate the kinds of predominant vegetation, the size and which effects the antropic action in the region has been causing on this big forest. The results indicate that the region is covered predominantly by Cerrado Latu Sensu and Forests, Decidual Submontana and Semidecidual, covering in 1966, 1799.091,63 ha and in 2007, 1693.797,40 ha. During the period evaluated, lost 10.19% of its vegetal cover, replaced by areas of pastures and agricultural cultures.
