Biological reserve

Brazil

In Brazil, nature reserves are classified by the National System of Nature Conservation Units as ecological stations (Portuguese: estações ecológicas) or biological reserves (Portuguese: reservas biológicas). Their main objectives are preserving fauna and flora and other natural attributes, excluding direct human interference. Visits are allowed only with permission, and only for educational or scientific purposes. Changes to the ecosystems in both types of reserve are allowed to restore and preserve the natural balance, biological diversity and natural ecological processes. Ecological stations are also allowed to change the environment within strictly defined limits (e.g. affecting no more than three percent of the area or 1,500 hectares (3,700 acres), whichever is less) for the purpose of scientific research. A wildlife reserve in Brazil is also protected, and hunting is not allowed, but products and by-products from research may be sold.
