The bush area is distinguished for presenting the biggest transformation related practises it of the deforestation and substitution of the native vegetation for pasture.

In 1965 the oupada area was of 3,1% and in 2000 it passes to 3,7%, indicating small transformations in entorno of the village Green Lemon. Figure 01 – Evolution of the use of the land and vegetal covering figure 02 represents the espacilizao of the four classrooms mapeadas for the year of 1965. A domain of the vegetal covering in relation is notable the other classrooms, over all in the areas of the springs of all hidrogrfica basin, what he contributes very in significant way with the maintenance of the ecological stability of this environment.
