Atsinanana Rainforests Page 2 Geographic Location Madagascar is located approximately 250 miles from the eastern coast of Africa and located on the eastern part of Madagascar is The Atsinanana Rainforest. Atsinanana Rainforests consists of six national parks. The Rainforest of Atsinanana was added as a World Heritage site because of its unique biodiversity. Madagascar separated from other land masses more than 60 million years ago (UNESCO, 2010).Having separated from the influences of other species and other land masses, Madagascar evolved independently with species not found in any other part of the world. The human species has been in the Atsinanana Rainforests only for the past 2,000 years. Supporting, conserving and preserving The Rainforest of Atsinanana is necessary to ensure the survival of many species not found elsewhere, perhaps even species not yet discovered. Weather and Climate

Atsinanana Rainforests Page 3 The climate in Madagascar is tropical with two main seasons and maintains an average temperate of 25 degrees Celsius (Cortez Travel, n.d.) . The area has torrential rains from November through March with occasional cyclones. During the rainy season, Madagascar’s rain fall varies from 12 to 350 inches of rainfall. The weather remains fairly dry and pleasant between April and October. The area is located south of the equator and is self contained on an island, but more resembles a mini-continent because of its size of over 1000 miles long and 350 miles wide (Cortez Travel, n.d.) . Madagascar is the world’s fourth largest island and contains six different micro climates ranging from tropical rainforests to dry deserts. With such diversity and its long time isolation, it is no wonder that so many endemic species have evolved in the Madagascar. Soil Madagascar is known as the Big Red Island due to its rich laterite soil. This soil is high in aluminum and iron oxide, of which the latter gives it its red color. According to the Encyclopedia Britannica, laterite soil is a horizon of soil that is formed from the physiochemical reactions with the climate and parent rock (Encyclopedia Britannica, 2011). The soil is usually

Atsinanana Rainforests Page 4 found in subtropical and tropical areas where there is higher humidity, which enables the physiochemical processing to take place. Worldwide Benefits Rain Forests provide a rich ecosystem approximately to 50% percent of the known species on Earth. Rainforests also helps in maintaining the climate worldwide by regulating gases in the atmosphere, stabilizing rainfall, and protects the world from desertification (the act of fertile land turning into desert land) worldwide (Butler, 2010) . Rainforests provide protection to many species during times of climate change.
