Two-thirds of all flowering plants can be found in rainforests. The Tropical Rainforest Geography . Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. The entire hydrologic cycle slowed, and tropical rainforests—which depend on both warmth and consistently high rainfall—became increasingly restricted to equatorial latitudes. About 1.6 billion people, more than 25% of the world’s population, rely on forest resources for their livelihoods, according to the UN Food and Agriculture Organization, and most of them (1.2 billion) depend on rainforests for their daily needs. Title: The Tropical Rainforest 1 (No Transcript) 2 The Tropical Rainforest By Bryson 3 Introduction. They are found all over the world but the majority of the tropical rainforest lies in South America in Brazil. Fact 26: Trees in tropical rainforests are so dense that it takes approximately 10 minutes for the rainfall to reach the ground from the canopy. Slash-and-burn forest clearing in the Amazon. Tropical forests and deforestation in the early 21st century. Fact 2: Rainforests are the forests that receive a high amount of rainfall. The Amazon rainforest is the world’s largest tropical rainforest. The water rainforests produce is evaporated and then used as rain in other areas. Even if you think that you can’t make a difference, you are wrong. Fact 22: A lot of the oxygen supply that we have throughout the world is supplied by the tropical rainforests because of the number of trees in the tropical rainforest biome, even though they are miles and miles away. Tropical rainforest ecosystems are the longest living ecosystems on the Earth … These various plants and animals provide food and nutrients, and have, for thousands of years, been used as medical plants to improve health conditions. Fact 36: In a 2017 analysis published in the scientific journal PNAS, climate scientists concluded that forest conservation/restoration, natural climate solutions and sustainable agriculture could provide more than one-third of the global climate mitigation required to stabilize warming to below 2 °C. Fact 16: There were around 6 million square miles of rainforest in the beginning, but now because of deforestation, there is only less than half of that still found in the world. Regrettably, tropical rainforests and tropical deciduous forests are now being destroyed at a rapid rate in order to provide resources such as timber and to create land that can be used for other purposes, such as cattle grazing (see deforestation). Further evidence comes from the growth forms of the most primitive surviving angiosperms: all 13 of the most primitive angiosperm families consist of woody plants, most of which are large trees. Fact 32: Variety of animals including snakes, frogs, birds, insects, cougars, chameleons, turtles, Bengal tigers, mountain gorillas, orangutans, jaguars and many more magnificent animals are found in tropical rainforests. It is known for its dense canopies of vegetation that form three different layers. It is so big that if it were a country, it would be the ninth biggest in the world. Here you will find 45+ remarkable facts about the tropical rainforest that you may not have known previously. Fact 46: Forests are natural water filters that keep pollution and debris from flowing into water supplies and slowing the movement of rainwater that it flows into underground reserves. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Tropical rainforest - Tropical rainforest - Environment: The equatorial latitude of tropical rainforests and tropical deciduous forests keeps day length and mean temperature fairly constant throughout the year. North of the Equator, there is a small amount of rainforest on America's Western Coast.

The tropical rainforests are important for a number of reasons to humans. Navigate parenthood with the help of the Raising Curious Learners podcast. Fact 18: 90% of the world’s forests is in underdeveloped or developed countries around the world. Fact 3: You can find rainforests in many countries, not just in South America. Of the 13 angiosperm families generally recognized as the most primitive, all but two—Magnoliaceae and Winteraceae—are overwhelmingly tropical in their present distribution. Within these belts, especially in continental interiors, deserts formed (see desert: Origin). Tropical rainforests regulate local climate by providing shade and returning water vapour to the atmosphere, humidifying and cooling the air; they also provide valuable pollination services. We have yet to identify all of the medicinal benefits that the plants of the tropical rainforest have to offer. Like all vegetation, however, that of the rainforest continues to evolve and change, so modern tropical rainforests are not identical with rainforests of the geologic past. A walk through a tropical rainforest in Tamborine National Park, Queensland, Australia, with a stop at Curtis Falls. They experience rainfall nearly every day and there is no dry season. Fact 45: A lake inside a rainforest on the Caribbean island of Dominica sizzles at around 88°C. Associate Professor of Geography and Planning, University of New England, Armidale, New South Wales. They hold enormous potential for future discoveries. Fact 1: Rainforests only cover around 2 percent the total surface area of the Earth and about 6% of the Earth‘s land surface, but about 50 percent of all known species of the plants and animals on the earth live in the rainforest. More than 2000 plant species found in the tropical rainforest contain cancer-fighting elements. Please select which sections you would like to print: Corrections? A mature lowland tropical forest consists of several layers. Tropical rainforests receive around 100 inches (254 centimeters) of rainfall yearly, and contain tall broad-leaved evergreen trees that form a continuous canopy. Trucks on a road transporting recently harvested logs near Sabah's border with Kalimantan in Borneo. A beam of sunlight makes its way through the leaves and lights up the brightly colored wings of a macaw. An alternative explanation for this geographic pattern is that in the Southern Hemisphere, especially on islands, there are more refugia—i.e., isolated areas whose climates remained unaltered while those of the surrounding areas changed, enabling archaic life-forms to persist. They are the temperate rainforests and tropical rainforests. If you haven’t taken any time to learn about the rainforest, then most of this information may actually be new to you. Landforms in the rainforest include valleys, rolling hills, old river basins, and level areas. Fact 28: More than 56,000 square miles of natural forest are lost each year. Station Leader, 1996 Australian National Antarctic Research Expedition to Macquarie Island, Australian... Rainforest vegetation grows along the northern coast of Ecuador. The rainfall gets at least 250cm and can reach up to 400-450 inches in one year. kids.mongabay.com - helping children learn about the rainforest Mongabay is the world's most popular site about the rainforest. Fact 10: Within four square miles of tropical rainforest, you will find 1500 flowering plant species, 750 types of trees, and many of these plants can be helpful in combating cancer. Fact 15: Rainforests are threatened each and every day, especially by practices such as agriculture, ranching, logging and mining. Five families—Amborellaceae, Austrobaileyaceae, Degeneriaceae, Eupomatiaceae, and Himantandraceae—are restricted to rainforests in the tropical Australasian region. Fact 25: Rainforests are continually being destroyed by multinational logging companies, landowners and state governments to make way for new colonies, industrial units. About; Contact . Fact 43: There is a surprising variety of animals. In the drier and more fire-prone places, savannas and tropical grasslands developed. The flowering plants (angiosperms) first evolved and diversified during the Cretaceous Period about 100 million years ago, during which time global climatic conditions were warmer and wetter than those of the present. (And How To Keep Them Away). Fact 9: Rainforests are so rich in biodiversity that about 1/4 of natural medicines have been discovered in rainforests. According to research published in the International Journal of Oncology, more than 60% of anticancer drugs originate from natural sources, including rainforest plants. The Korowai people of New Guinea live in tree houses as high as 45m off the ground! True rainforests are typically found between 10 degrees north and south of the equator (see map); they are a sub-set of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn The Jungle is also called the Tropical Rainforest. Tropical rainforests grow mainly in three regions: the Malesian botanical subkingdom, which extends from Myanmar (Burma) to Fiji and includes the whole of Thailand, Malaysia, Indonesia, the Philippines, Papua New Guinea, the Solomon Islands, and Vanuatu and parts of Indochina and tropical Australia; tropical South and Central America, especially the Amazon basin; and West and Central Africa (see biogeographic region). As the rainforest species disappear, so do many possible cures for life-threatening diseases. A number of the fruits we eat every year are pollinated by the bats that call the rain forest home. Each one is perfect for survival in the moist Jungle. (And How to Keep Them Away), Do Deer Eat Peonies? Fact 44: Some people choose to live in the tropical rainforest and become farmers for the food and spices people eat. Jungles are always found close to the equator. The Tropical Rainforest Rainforest Series, Part 1 - by Mikki Sadil Tropical rainforests are among the most mysterious of all geographical biomes in the world. Tropical rainforests are the most biologically diverse terrestrial ecosystems in the world. If you have learned about it, whether from school or other sources, then you may know most of this information, if not all of it. If we lose the rainforest, we eliminate the possibility of discovering new types of cancer treatments. In terms of biome classification a tropical rainforest is considered a lowland equatorial evergreen rainforest. (And Ways To Protect Peonies), Do Deer Eat Roses? *The tropical rainforests have different layers; the emergent layer, canopy layer, understory layer, and forest floor layer. Rainforests add water to the atmosphere through the process of transpiration, by which plants release water during photosynthesis from their leaves. Some even have a thickness that equals the circumference of a human being. The tropical rainforest is very rainy, as its name implies. Fact 35: About 70% of the plants identified by the U.S. National Cancer Institute, which can be used in the treatment of cancer, are found only in rainforests. RAINFOREST FACTS. Today tropical forests, more than any other ecosystem, are experiencing habitat alteration and species extinction on a greater scale and at a more rapid pace than at any other time in their history—at least since the major extinction event (the K–T extinction) at the end of the Cretaceous Period, some 66 million years ago (see Sidebar: Status of the World’s Tropical Forests). (And Ways to Reuse Old Bottles), 13 Amazing Plants That Do Not Need Drainage Holes, Do Deer Eat Petunias? Many extinctions resulted. Fact 11: 70% or more of the plants that are used to treat cancer are found only in the tropical rainforests on the planet. According to Global Forest Watch, our planet loses tropical forestland equivalent to the size of Bangladesh every year. If you don’t know too much about tropical rainforests, then you will probably be surprised to find that there are a few little known facts out there about them. In these areas new plant forms evolved from tropical rainforest ancestors to cope with seasonally dry weather, forming tropical deciduous forests. It isn’t just the oxygen that helps us breathe that we need from the rainforests. The geography of the rainforest varies depending on where it is, it includes landforms, elevation, soil, and resources. In the rainforest, trees grow to gigantic size, supported by strong, strut-like buttresses at the base of the trunk that help to stabilize them in shallow forest soils. The principal areas of tropical deciduous forest (or monsoon forests) are in India, the Myanmar–Vietnam–southern coastal China region, and eastern Brazil, with smaller areas in South and Central America north of the Equator, the West Indies, southeastern Africa, and northern Australia. The tropical rainforest temperature is around 86 to 95 degrees Fahrenheit during the day and at night it drops to about 68 to 77 degrees Fahrenheit. Fact 23: The average temperature of the tropical rainforest remains between 70 and 85° F. Fact 24: Timber, coffee, cocoa and many medicinal products are few of the products produced by rainforests, including those used in the treatment of cancer. Of particular interest is the fact that the majority of flowering plants displaying the most primitive characteristics are found in rainforests (especially tropical rainforests) in parts of the Southern Hemisphere, particularly South America, northern Australia and adjacent regions of Southeast Asia, and some larger South Pacific islands. Everyone can make a difference, and when you think about it – you have to be the change that you would like to see in the world, and if you do this and set a great example, others will do the same. In regions lying between the wet tropics and the deserts, climatic zones developed in which rainfall adequate for luxuriant plant growth was experienced for only a part of the year. Compounds in rainforest plants are already used to treat malaria, heart disease, arthritis, bronchitis, diabetes, dysentery, glaucoma, hypertension, muscle tension, rheumatism, and tuberculosis, among other health problems. Sidebar: Status of the World’s Tropical Forests. They also cool and regulate local micro-climates limiting the Earth’s reflectivity that stabilizes ocean currents, wind, and rainfall patterns. A tree known as the idiot fruit grows in Australia‘s Daintree rainforest. You can find tropical rainforests in Central America, South America, Mexico, Asia, Africa, Australia. A biome is an area with very distinctive plants and animals that have adapted to life in that particular environment. A true environmentalist by heart ❤️. Rainforests provide people with many cooking spices such as vanilla, allspice, and black pepper. Omissions? tropical rainforest A forest with high rate of precipitation and high humidity, usually located near the equator (Tropical Rainforests) contain at least one-half of the world's species of plants and animals and are dominated by tall, broad-leaved trees. The weather in the tropical rainforest is rainy yet pleasant all year round, day … While 25% of Western pharmaceuticals are derived from rainforest ingredients, less that 1% of these tropical trees and plants have been tested by scientists. Fact 8: Rainforests play an essential role in maintaining the Earth’s limited supply of drinking water and freshwater, so they are crucial to the sustainability of the earth. In 2017 alone, we lost 15.8 million hectares of tropical forests; all told, humans have destroyed nearly half of the world’s original forest cover. Fact 31: A slice of the rainforest, approximately equivalent to the size of rainforest destroyed each second, which is equivalent to 86,400 football fields of rainforest each day, which is equal to 31 million football fields of rainforest each year. Tropical rainforests are wet and hot year-round and have nutrient poor soil (most of the nutrients are… The rainforests are divided in two types. Try to learn more about the tropical rainforests and what you can do to help preserve them. The sun rises daily to a near-vertical position at noon, ensuring a high level of incoming radiant energy at all seasons. Fact 3: You can find rainforests in many countries, not just in South America. Fact 40: Most of the animals living in tropical rainforest live in the trees. (And What to Do With Old Junk Mail), Can You Recycle Lighters? While it is possible that even earlier forms existed that await discovery, the oldest angiosperm fossils—leaves, wood, fruits, and flowers derived from trees—support the view that the earliest angiosperms were rainforest trees. There they can find all of their necessities and rarely have to come down to the floor of the forest. The tropical rainforest of Africa was the habitat in which the ancestors of humans evolved, and it is where the nearest surviving human relatives—chimpanzees and gorillas—live still. However, in some regions a long history of forest burning by the inhabitants is thought to have caused extensive replacement of tropical rainforest and tropical deciduous forest with savanna. Tropical rainforests cover only 2 percent of the Earth’s surface, but they have an outsize impact on providing habitat, storing carbon and regulating the flow of water. Tropical rainforests (world's most important ecosystems all over the planet). Most of the smaller, more delicate plants that are so widespread in the world today evolved later, ultimately from tropical rainforest ancestors. The tropical rainforest is a fascinating part of ecology to study, with its huge variety of plants and animals. Flying animals of Asian rainforests include frogs, squirrels and snakes. If you think about how much of an impact the rainforests actually have on our life, even if we don’t live anywhere near a rainforest, you will really see the importance of keeping them around. Fact 10: Within four square miles of tropical rainforest, you will find 1500 flowering plant species, 750 types of trees, and many of these plants can help combat cancer. Rainforest is described as a tall, hot and dense forest near the equator and is believed to be the oldest living ecosystem on Earth, which gets the maximum amount of rainfall. Updates? Deforestation reduces the moisture released into the atmosphere decreasing rainfall and leading to drought. Also, there are vast amounts of species residing in the tropical rainforest. Top 10 Facts: Rainforest habitats are forests located around the tropics, which is a zone around the equator. Over 30,000 species of plants have discovered, while another 20,000 are said to be undiscovered. As the world climate cooled in the middle of the Cenozoic, it also became drier. This has led some authorities to suggest that the original cradle of angiosperm evolution might lie in Gondwanaland, a supercontinent of the Southern Hemisphere thought to have existed in the Mesozoic Era (252 to 66 million years ago) and consisted of Africa, South America, Australia, peninsular India, and Antarctica. This section provides information about tropical rainforests in a format suitable for children as well as rainforest materials for educators. The world's largest rainforest is the Amazon rainforest; Brazil has the largest extent of rainforest cover, including nearly two-thirds of the Amazon. Tropical rainforest, also spelled tropical rain forest, luxuriant forest found in wet tropical uplands and lowlands around the Equator. A tropical rain forest has more kinds of trees than any other area in the world. Species have adapted to the conditions of the rainforest, eg trees and plants have shallow-reaching roots to absorb nutrients from the thin fertile layer in the soil. Cloud forests can be at more than 10,500 feet above sea level. Fact 6: Rainforests help to regulate the temperatures around the world and the weather patterns as well.
