Earth Floor: Biomes Tropical Rainforest The tropical rainforest is a hot, moist biome found near Earth's equator. The world's largest tropical rainforests are in South America, Africa, and Southeast Asia. Tropical rainforests receive from 60 to 160 inches of precipitation that is fairly evenly distributed throughout the year. The combination of constant warmth and abundant moisture makes the tropical rainforest a suitable environment for many plants and animals. Tropical rainforests contain the greatest biodiversity in the world. Over 15 million species of plants and animals live within this biome.
Calculating Deforestation in the Amazon Calculating Deforestation Figures for the Amazon These figures are calculated from estimates provided by the Brazilian National Institute of Space Research (INPE) and the United Nations Food and Agriculture Organization (FAO). The figures only refer to the Brazilian Amazon, which accounts for roughly 60 percent of the Amazon rainforest. According to a study released in September 2009 by Brazil's National Institute for Space Research (INPE), at least 20 percent land deforested in the Brazilian Amazon is regrowing forest. Please note: Amazon deforestation data is updated several times a year here.
Tropical rainforest climate Worldwide zones of Tropical rainforest climate (Af). A tropical rainforest climate, also known as an equatorial climate, is a tropical climate usually (but not always) found along the equator. Regions with this climate typically feature tropical rainforests, and it is designated by the Köppen climate classification. Description fires-could-turn-amazon-rainforest-into-a-desert-as-human-activity-and-climate-change-threaten-lungs-of-the-world-says-study-9259741 One of the last great wildernesses on earth – known as the lungs of the world – is balancing dangerously close to a “tipping point” where forest fires will become so commonplace and extensive that they will change much of the landscape forever, scientists said. Although fires have always occurred in Amazonia, they have been largely controlled by the natural humidity of the region. Now, however, the drying out of the rainforest threatens to ignite the tree-filled habitat – with its rich biodiversity – and convert it almost overnight into barren desert, they warned. For the first time, scientists have shown in experiments on the ground how extreme, dry weather combined with the effects of human activities can create a tinderbox environment where intensely damaging forest fires can spread easily, killing trees that have taken hundreds of years to grow. The researchers monitored the three 50-hectare plots of Amazon rainforest over an eight-year period.
Population Decline of Indigenous People Indigenous peoples inhabit a large portion of the Amazon rainforest and their traditional and cultural beliefs have existed for centuries, providing storage for an immense amount of knowledge about the tropical Amazon. In contrast, the non-indigenous population of the Amazon is exploding. From the 1960’s until the late 1990’s, this number grew from 2 million to around 20 million.  As the development of infrastructure projects continues within the Amazon rainforest, migration of non-traditional peoples will increase and come into conflict with traditional forest-dwellers, particularly those not protected by reserves. Of the indigenous groups that were known to exist in 1900, one-third of these groups are now extinct.  With the loss of these populations follows devastating losses of cultural diversity, treasure troves of anthropological information, and partners for the future of conservation in the Amazon.
Fact sheet: Tropical Rainforest Animals Where can you find an antelope the size of a rabbit, a snake that can fly, or a spider that eats birds? All in tropical rainforests, of course! Tropical rainforests are home to the largest and the smallest, the loudest and the quietest of all land animals, as well as some of the most dangerous, most beautiful, most endearing and strangest looking animals on earth. You've probably heard of some of them: jaguars, toucans, parrots, gorillas, and tarantulas all make their home in tropical rainforests. But have you ever heard of the aye-aye? Or the okapi?
Rainforest Biomes The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 °F (34 °C) or drops below 68 °F (20 °C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. Amazon deforestation jumps in Brazil, but remains historically low Deforestation jumped 16 percent in the Brazilian Amazon to 5,831 square kilometers for the year ended July 31, 2015, but still remained well below historical levels, according to data released Thursday Brazil’s National Space Research Institute (INPE). The rise, which was announced just ahead of the opening of U.N. climate talks in Paris, had been widely anticipated based on data from short-term satellite-based monitoring systems. Climbing deforestation has been attributed to several factors, including Brazil’s flagging economy and currency, which makes forest conversion for agriculture more attractive; the government’s steep cuts in funding for programs to reduce deforestation; a renewed push for large-scale infrastructure projects in the Amazon; and relaxation of the country’s Forest Code, which governs how much forest must be preserved on private lands. The latest INPE data are preliminary.
