Petrópolis Environmental Protection Area

Petrópolis Environmental Protection Area (Área de Proteção Ambiental da Região Serrana de Petrópolis) is a protected area of Rio de Janeiro state, Brazil.

Location
The protected area in the Atlantic Forest biome, which covers 68224 ha, was created on 20 May 1992. It is administered by the Chico Mendes Institute for Biodiversity Conservation. It includes the Serra dos Órgãos National Park. It contains all or part of the municipalities of Petrópolis, Magé, Guapimirim and Duque de Caxias in Rio de Janeiro state.

Environment
Rainfall averages 2000 mm annually. Temperatures range from 10 to 28 C, with an average of 18 C. Altitude ranges from 100 to 2000 m. The area lies in the orogenic belt of the state of Rio de Janeiro, in the Mantiqueira geological province of the Brazilian platform. Streams and rivers typically have rocky beds and slope steeply, running rapidly after rainfall. The rivers originating in the protection area flow south into Guanabara Bay or north to the Paraíba do Sul. The vegetation is classified as Tropical Rain Forest or Atlantic Forest, but varies greatly due to differences in altitude and the orientation of the slopes. Most of the species are evergreen, since dry periods are short or non-existent in the region.

Conservation
The environment protection area is classed as IUCN protected area category V, protected landscape/seascape. The purpose is to ensure the preservation of the Atlantic Forest ecosystem and the sustainable use of natural resources while conserving the cultural landscape and improving the quality of human life in the region. The conservation unit is in the Central Rio de Janeiro Atlantic Forest Mosaic, created in 2006. Problems include the expansion of urban areas, which has led to poorly planned clearance of slopes causing the risk of landslides, deforestation, and inappropriate agricultural practices including cattle grazing and pasture burning that contribute to soil degradation.
