Private Reserves of Natural Heritage, also known as RPPN, are areas of environmental conservation in private lands, recognized by the National System of Conservation Units (SNUC) as a category of Conservation Unit. The RPPN is created based on the will of the owner, who is committed to conserving nature, ensuring that the area is protected forever, as it is of a perpetual nature.
The RPPN must have a management plan to guarantee the continuity of natural resources and ecological processes, admitting activities of environmental education and scientific research, in addition to ecotourism, which can become a source of income for the property.
In the RPPN, the owner of the land remains the owner, who now has the support of environmental inspection and protection bodies, in addition to environmental organizations.
