It was found that the PPAs in the rivers and springs cover an area of 296.22 ha, representing 4% of the total basin area, whose total area is 7405.16 ha. During the analyzed interval (1990-2014), a quantified deforestation 4270.51 ha (57.66%) of the forest cover of the basin. It was found that there 65.64 (22.16%) of APP have been cleared. The main land use in the basin is pasture with 4966.61 ha (67.06%).
