This article presents an in-depth analysis of use and conservation of natural resources and common pool resources, mainly remaining forest in protected areas. The use and management of common pool resources reflect different analysis, being the basis of this article the debate between Garrett Hardin and Elinor Ostrom. In an antagonist perspective Garret Hardin issues the problems of the collective use of these resources with external regulators to avoid over exploration while Elinor Ostrom observes a greater autonomy of the communities on the sustainable use of these resources. The distinctive views present counterpoints between the inclination of coercive legal means and the own controls of the community. From the principles defined by Elinor Ostrom, this text presents the evaluation of the institutional performance of two cases in "bairros Cota", located in the "Serra do Mar" State Park.
