The municipality also has about 5% of its original native vegetation preserved. Of this total, almost all is composed of vegetation on slopes. Savannah and broad-leaved tropical forest species still exist in small isolated areas, although they have been almost completely decimated due to agriculture and stock breeding. The presence of numerous rock walls and slopes that sprang from the "cuestas", primarily an "embarrassment" for the settlers from the beginning of the 20th century, preserved this natural and important sanctuary treasure for biodiversity in the state of Sao Paulo.
