The lack of information about the diversity of frogs and the speed of change in the landscape that have been taking place on the planet, demonstrates the urgent need to preserve the remaining resources. In this adverse scenario, live frogs that are sensitive to changes in natural forest areas, and are recognized as Bioindicator of environmental integrity. The present study had scoped to do a survey of the anuran species in a country area, near to the city of Porto Velho (RO). This land, is formed by two separate areas, one classified as secondary forests and the other as pasture area.
