Rainforest
Rainforests are forests characterized by high rainfall, with annual rainfall between 250 and 450 centimetres (98 and 177 in).[1] There are two types of rainforest: tropical rainforest and temperate rainforest. The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests. Tropical Tropical rainforests are characterized by a warm and wet climate. Many of the world's rainforests are associated with the location of the monsoon trough, also known as the intertropical convergence zone.[7] Tropical rainforests are located in the tropics, i.e., in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn. Temperate Layers A tropical rainforest is typically divided into four main layers, each with different plants and animals adapted for life in that particular area: the emergent, canopy, understorey/understory and forest floor layers.

Why Save the Rain Forest? Imagine what it is like to walk through a rain forest. You pass hundreds of trees, many more than 125 feet high. You see orchids, ferns, and other exotic plants growing on tree trunks. Above, sunlight filters through the canopy of leaves, but you are walking in deep shade. You have probably heard how important rain forests are. Why Save the Rain Forests explains how rain forests touch everyone's life. Plants from the rain forest provide us with many other important things. What if there were no more rain forests? Where rain forests have been cleared from the land, much less rain falls. What can you do to save the rain forests? Best Way - Amazon Rainforest Survival Guide Despite the fact the Amazon rainforest is progressively dwindling due to deforestation, it is still vast and people find themselves needing to survive in it on a regular basis. So it is important to know how to survive in this type of seemingly impenetrable, endless jungle if you are unfortunate enough to find yourself stranded there for an extended period of time. While access to food and water are the first concerns, keeping yourself safe from wild animals and knowing what not to consume is also important. Water Considerations While it is a rainforest, which by definition means it rains regularly, it is still rather difficult to obtain water which is not contaminated and is safe for you to drink. Edible Plants There are many plants or fruits from these plants which can be eaten. Animal Hunting and Protection It is also important to set traps for animals, not only to catch them but to protect yourself from them at night. More slideshows

Tropical Rainforest Where are tropical rainforests found? Tropical rainforests are located around the equator where temperatures stay near 80 degrees year round. Rainforests receive 160 to 400 inches (400-1000 cm) of rain each year. The largest rainforests are in Brazil (South America), Zaire (Africa) and Indonesia (South East Asia). Other tropical rainforest places are in Hawaii and the islands of the Pacific & Caribbean. What is the tropical rainforest? The Tropical Rainforest is a forest occurring in tropical areas of heavy rainfall. What is the structure of vegetation in the rainforest? The image above shows a typical cross section in the rainforest. Emergents are the tallest trees and are usually over 50 metres tall. The sea of leaves blocking out the sun from the lower layers is called the canopy. The under canopy mainly contains bare tree trunks and lianas. The shrub layer has the densest plant growth. The forest floor is usually dark and damp. How did the tropical rainforest get like this? Local: Global:

Rain Forest Threats, Rain Forest Species More than half of Earth’s rain forests have already been lost forever to the insatiable human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent. And if current deforestation rates continue, these critical habitats could disappear from the planet completely within the next hundred years. The reasons for plundering rain forests are mainly economic. Threats Solutions 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. Rainforests now cover less than 6% of Earth's land surface. A tropical rain forest has more kinds of trees than any other area in the world. About 1/4 of all the medicines we use come from rainforest plants. All tropical rain forests resemble one another in some ways. Despite these differences, each of the three largest rainforests--the American, the African, and the Asian--has a different group of animal and plant species. Layers of the Rainforest There are four very distinct layers of trees in a tropical rain forest. Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Plant Life Besides these four layers, a shrub/sapling layer receives about 3 % of the light that filters in through the canopies. Animal Life

Live Science: Deforestation Deforestation is the permanent destruction of forests in order to make the land available for other uses. An estimated 18 million acres (7.3 million hectares) of forest, which is roughly the size of the country of Panama, are lost each year, according to the United Nations' Food and Agriculture Organization (FAO). Some other statistics: About half of the world's tropical forests have been cleared (FAO) Forests currently cover about 30 percent of the world’s land mass (National Geographic) Forest loss contributes between 6 percent and 12 percent of annual global carbon dioxide emissions (Nature Geoscience) About 36 football fields worth of trees lost every minute (World Wildlife Fund (WWF)) Deforestation occurs around the world, though tropical rainforests are particularly targeted.

Tropical rainforest A tropical rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall. Rainforests can be found in Asia, Australia, Africa, South America, Central America, Mexico and on many of the Pacific, Caribbean, and Indian Ocean islands. Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical wet forest (or tropical moist broadleaf forest) and may also be referred to as lowland equatorial evergreen rainforest.[3] Overview[edit] Tropical rainforests can be characterized in two words: hot and wet. Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation as a result of human activity. History[edit] Tropical rainforests have existed on Earth for hundreds of millions of years. Forest floor[edit]

Example: Campa Pita, Belize Description There are two types of rainforests, tropical and temperate. The tropical rainforest is a hot, moist biome where it rains all year long. 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[edit] Distribution[edit] Upland rainforest in Borneo. A tropical rainforest climate is usually found at latitudes within five degrees North and south of the equator, which are dominated by the Intertropical Convergence Zone. Some of the places that have this climate are indeed uniformly and monotonously wet throughout the year (e.g., the northwest Pacific coast of South and Central America, from Ecuador to Costa Rica, see for instance, Andagoya, Colombia), but in many cases the period of higher sun and longer days is distinctly driest (as at Palembang, Indonesia) or the time of lower sun and shorter days may have more rain (as at Sitiawan, Malaysia).
