Resumo
The Savanna’s biome was intensively occupied after governmental projects and policies
as II National Developpinent Planning promoting the substitutions of natural physiognomic
Savanna’s covers by modern agriculture and pastures and several negatives impacts on the
environment related to intensive and rapid deforestation. One of consequences was an increase
of isolated fragments from Savanna cover. The aim of this article is to present the land use maps
of that basin and to quantify and spatialize the existent remainders of Savannah. They was made
over Landsat ETM 7+ (2003) satellite image crossing visual and digital interpretations followed by
field control. The results show 44,79% of total area is occupied by savanna fragments cover and
55,21% by pastures tends in view that the remainders are more concentrated in the northeast
portion of the basin.
