Serra do Mar

geography Maturity 5-7 Next article →

The Serra do Mar is a vast system of mountain ranges and escarpments. It is located in Southeastern Brazil. This geological feature runs parallel to the Atlantic Ocean coast. The range stretches from the state of Espírito Santo to southern Santa Catarina. Some scientific literature suggests it includes the Serra Geral. In that case, the range would extend to northeastern Rio Grande do Sul.

The main escarpment acts as a massive physical boundary. It separates the sea-level littoral from the inland plateau, known as the planalto. The planalto has a mean altitude of 500 meters. This escarpment is a component of the Great Escarpment. This much larger feature runs along much of the eastern coast of Brazil. It begins far to the north near the city of Salvador, Bahia.

The mountain ranges are not a single, continuous line. They are discontinuous in several different places. Because of this, many sections have their own specific names. These include the Serra de Bocaina and the Serra de Paranapiacaba. Other named sections are Serra Negra, Serra dos Órgãos, and Serra do Indaiá. The range also extends to large islands near the coast. These islands include Ilhabela and Ilha Anchieta.

Geologically, the range is part of a massive crystalline rock platform. This platform forms much of Eastern South America. Tectonically, the region is considered very stable. Most of the elevations in the Serra do Mar formed about 60 million years ago. One of the highest points is Pico da Caledônia. It is located in Nova Friburgo. The area is also known for mineral beauty, such as amethyst.

In the year 1500, during the European discovery of Brazil, the area was very different. The mountains supported a highly diversified ecosystem. This ecosystem was composed mainly of a lush tropical rain forest. This forest is called the Atlantic Forest, or Mata Atlântica.

It was once a massive, continuous cover of greenery. However, urbanization and deforestation have changed the landscape significantly.

Much of the original forest cover has been destroyed over time. What little forest remains is found almost exclusively on steep escarpments. These are the cliffs that face the sea. Large metropolises are located near the Serra do Mar. These cities include Rio de Janeiro and São Paulo. Other nearby large cities include Curitiba and Vale do Itajaí. The proximity of these urban areas puts pressure on the natural environment.

Protecting the Mata Atlântica is a major challenge. A chain of national and state parks exists to help. There are also ecological stations and biological reserves. These areas aim to protect the biological heritage of the forest. However, the forest faces many active threats. These include acid rain and pollution. Poachers and clandestine loggers also cause damage. Forest fires and encroachment by farms and cities are constant issues.

Reforestation is notoriously difficult in these destroyed habitats.
