Brazilian Highlands Information & Brazilian Highlands Links at HealthHaven.com

The Brazilian highlands (Portuguese: Planalto Brasileiro) are an extensive geographical region, covering most of the eastern, southern and central portions of Brazil, in all approximately half of the country's land area, or some 4,000,000 km² (1,544,000 sq mi). In addition, the vast majority of Brazil's population (186,112,794 2004 est.) lives in the highlands or on the narrow coastal region immediately adjacent to it.

Ancient basaltic lava flows gave birth to much of the region. However, the time of dramatic geophysical activity is long past, as there is now no seismic or volcanic activity. Erosion has also played a large part in shaping the Highlands, forming extensive sedimentary deposits and wearing down the mountains.

The Brazilian Highlands are notable for the great diversity to be found there: within the region there are several different biomes, vastly different climatic conditions, many types of soil, and thousands of animal and plant species.

[edit] Major divisions

Due to their size and diversity, the Brazilian Highlands are usually divided into three main areas:

Atlantic Plateau, extending all along the eastern coast of Brazil, and including several mountain ranges. It was once almost completely covered by the Atlantic Rainforest, one of the richest areas of biodiversity in the world, of which only 7.3% remains.
Southern Plateau, advancing inland in the southern and southern-central portions of the country. Sedimentary rocks covered partially by basaltic lava spills that form the fertile ground known as "purple land". Large portions of this region were also covered by the Atlantic Rainforest, while araucaria highland forest and cerrado grasslands took up much of the rest.
Central Plateau, occupying the central portions of Brazil, with sedimentary and crystalline formations. Approximately 85% was once covered by cerrado vegetation, of which only a small portion remains intact.

In addition to the plateau regions, several adjoining or enclosed mountain ranges are considered to be part of the Brazilian Highlands. Some of the most important are (from north to south):

The highest point of the Brazilian Highlands is the Pico da Bandeira in the Serra do Caparaó, which stands at 2,891 meters (9,485 ft).
