Primitive tropical rainforest in Palawan

Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described.

Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests.[1] There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the «jewels of the Earth» and the «world’s largest pharmacy», because over one quarter of natural medicines have been discovered there.[2]

Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere.[3]

Definition

Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf litter, the presence of epiphytes and lianas and the absence of wildfire. The largest areas of rainforest are tropical or temperate rainforests, but other vegetation associations including subtropical rainforest, littoral rainforest, cloud forest, vine thicket and even dry rainforest have been described.[4][5][6][7][8]

Tropical rainforest

Location of tropical (dark green) and temperate/subtropical (light green) rainforests in the world.

Worldwide tropical rainforest climate zones.

Tropical rainforests are characterized by a warm and wet climate with no substantial dry season: typically found within 10 degrees north and south of the equator. Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year.[9] Average annual rainfall is no less than 168 cm (66 in) and can exceed 1,000 cm (390 in) although it typically lies between 175 cm (69 in) and 200 cm (79 in).[10]

Many of the world’s tropical forests are associated with the location of the monsoon trough, also known as the intertropical convergence zone.[11] The broader category of tropical moist forests are located in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn. Tropical rainforests exist in Southeast Asia (from Myanmar (Burma)) to the Philippines, Malaysia, Indonesia, Papua New Guinea and Sri Lanka; also in Sub-Saharan Africa from the Cameroon to the Congo (Congo Rainforest), South America (e.g. the Amazon rainforest), Central America (e.g. Bosawás, the southern Yucatán Peninsula-El Peten-Belize-Calakmul), Australia, and on Pacific Islands (such as Hawaiʻi). Tropical forests have been called the «Earth’s lungs», although it is now known that rainforests contribute little net oxygen addition to the atmosphere through photosynthesis.[12][13]

Temperate rainforest

Tropical forests cover a large part of the globe, but temperate rainforests only occur in few regions around the world.[14][15] Temperate rainforests are rainforests in temperate regions. They occur in North America (in the Pacific Northwest in Alaska, British Columbia, Washington, Oregon and California), in Europe (parts of the British Isles such as the coastal areas of Ireland and Scotland, southern Norway, parts of the western Balkans along the Adriatic coast, as well as in Galicia and coastal areas of the eastern Black Sea, including Georgia and coastal Turkey), in East Asia (in southern China, Highlands of Taiwan, much of Japan and Korea, and on Sakhalin Island and the adjacent Russian Far East coast), in South America (southern Chile) and also in Australia and New Zealand.[16]

Dry rainforest

Dry rainforests have a more open canopy layer than other rainforests,[17] and are found in areas of lower rainfall (630–1,100 mm (25–43 in)). They generally have two layers of trees.[18]

Layers

A tropical rainforest typically has a number of layers, each with different plants and animals adapted for life in that particular area. Examples include the emergent, canopy, understory and forest floor layers.[19][20]

Emergent layer

The emergent layer contains a small number of very large trees called emergents, which grow above the general canopy, reaching heights of 45–55 m, although on occasion a few species will grow to 70–80 m tall.[21][22] They need to be able to withstand the hot temperatures and strong winds that occur above the canopy in some areas. Eagles, butterflies, bats and certain monkeys inhabit this layer.

Canopy layer

The canopy layer contains the majority of the largest trees, typically 30 metres (98 ft) to 45 metres (148 ft) tall. The densest areas of biodiversity are found in the forest canopy, a more or less continuous cover of foliage formed by adjacent treetops. The canopy, by some estimates, is home to 50 percent of all plant species. Epiphytic plants attach to trunks and branches, and obtain water and minerals from rain and debris that collects on the supporting plants. The fauna is similar to that found in the emergent layer but more diverse. A quarter of all insect species are believed to exist in the rainforest canopy. Scientists have long suspected the richness of the canopy as a habitat, but have only recently developed practical methods of exploring it. As long ago as 1917, naturalist William Beebe declared that «another continent of life remains to be discovered, not upon the Earth, but one to two hundred feet above it, extending over thousands of square miles.» A true exploration of this habitat only began in the 1980s, when scientists developed methods to reach the canopy, such as firing ropes into the trees using crossbows. Exploration of the canopy is still in its infancy, but other methods include the use of balloons and airships to float above the highest branches and the building of cranes and walkways planted on the forest floor. The science of accessing tropical forest canopy using airships or similar aerial platforms is called dendronautics.[23]

Understory layer

The understory or understorey layer lies between the canopy and the forest floor. It is home to a number of birds, snakes and lizards, as well as predators such as jaguars, boa constrictors and leopards. The leaves are much larger at this level and insect life is abundant. Many seedlings that will grow to the canopy level are present in the understory. Only about 5% of the sunlight shining on the rainforest canopy reaches the understory. This layer can be called a shrub layer, although the shrub layer may also be considered a separate layer.

Forest floor

The forest floor, the bottom-most layer, receives only 2% of the sunlight. Only plants adapted to low light can grow in this region. Away from riverbanks, swamps and clearings, where dense undergrowth is found, the forest floor is relatively clear of vegetation because of the low sunlight penetration. It also contains decaying plant and animal matter, which disappears quickly, because the warm, humid conditions promote rapid decay. Many forms of fungi growing here help decay the animal and plant waste.

Flora and fauna

More than half of the world’s species of plants and animals are found in rainforests.[24] Rainforests support a very broad array of fauna, including mammals, reptiles, amphibians, birds and invertebrates. Mammals may include primates, felids and other families. Reptiles include snakes, turtles, chameleons and other families; while birds include such families as vangidae and Cuculidae. Dozens of families of invertebrates are found in rainforests. Fungi are also very common in rainforest areas as they can feed on the decomposing remains of plants and animals.

The great diversity in rainforest species is in large part the result of diverse and numerous physical refuges,[25] i.e. places in which plants are inaccessible to many herbivores, or in which animals can hide from predators. Having numerous refuges available also results in much higher total biomass than would otherwise be possible.[26][27]

Some species of fauna show a trend towards declining populations in rainforests, for example, reptiles that feed on amphibians and reptiles. This trend requires close monitoring.[28] The seasonality of rainforests affects the reproductive patterns of amphibians, and this in turn can directly affect the species of reptiles that feed on these groups,[29] particularly species with specialized feeding, since these are less likely to use alternative resources.[30]

Soils

Despite the growth of vegetation in a tropical rainforest, soil quality is often quite poor. Rapid bacterial decay prevents the accumulation of humus. The concentration of iron and aluminium oxides by the laterization process gives the oxisols a bright red colour and sometimes produces mineral deposits such as bauxite. Most trees have roots near the surface because there are insufficient nutrients below the surface; most of the trees’ minerals come from the top layer of decomposing leaves and animals. On younger substrates, especially of volcanic origin, tropical soils may be quite fertile. If rainforest trees are cleared, rain can accumulate on the exposed soil surfaces, creating run-off, and beginning a process of soil erosion. Eventually, streams and rivers form and flooding becomes possible. There are several reasons for the poor soil quality. First is that the soil is highly acidic. The roots of plants rely on an acidity difference between the roots and the soil in order to absorb nutrients. When the soil is acidic, there is little difference, and therefore little absorption of nutrients from the soil. Second, the type of clay particles present in tropical rainforest soil has a poor ability to trap nutrients and stop them from washing away. Even if humans artificially add nutrients to the soil, the nutrients mostly wash away and are not absorbed by the plants. Finally, these soils are poor due to the high volume of rain in tropical rainforests washes nutrients out of the soil more quickly than in other climates.[31]

Effect on global climate

A natural rainforest emits and absorbs vast quantities of carbon dioxide. On a global scale, long-term fluxes are approximately in balance, so that an undisturbed rainforest would have a small net impact on atmospheric carbon dioxide levels,[32] though they may have other climatic effects (on cloud formation, for example, by recycling water vapour). No rainforest today can be considered to be undisturbed.[33] Human-induced deforestation plays a significant role in causing rainforests to release carbon dioxide,[34][35][36] as do other factors, whether human-induced or natural, which result in tree death, such as burning and drought.[37] Some climate models operating with interactive vegetation predict a large loss of Amazonian rainforest around 2050 due to drought, forest dieback and the subsequent release of more carbon dioxide.[38]

Human uses

Tropical rainforests provide timber as well as animal products such as meat and hides. Rainforests also have value as tourism destinations and for the ecosystem services provided. Many foods originally came from tropical forests, and are still mostly grown on plantations in regions that were formerly primary forest.[39] Also, plant-derived medicines are commonly used for fever, fungal infections, burns, gastrointestinal problems, pain, respiratory problems, and wound treatment.[40] At the same time, rainforests are usually not used sustainably by non-native peoples but are being exploited or removed for agricultural purposes.

Native people

On January 18, 2007, FUNAI reported also that it had confirmed the presence of 67 different uncontacted tribes in Brazil, up from 40 in 2005. With this addition, Brazil has now overtaken the island of New Guinea as the country having the largest number of uncontacted tribes.[41] The province of Irian Jaya or West Papua in the island of New Guinea is home to an estimated 44 uncontacted tribal groups.[42] The tribes are in danger because of the deforestation, especially in Brazil.

Central African rainforest is home of the Mbuti pygmies, one of the hunter-gatherer peoples living in equatorial rainforests characterised by their short height (below one and a half metres, or 59 inches, on average). They were the subject of a study by Colin Turnbull, The Forest People, in 1962.[43] Pygmies who live in Southeast Asia are, amongst others, referred to as «Negrito».
There are many tribes in the rainforests of the Malaysian state of Sarawak. Sarawak is part of Borneo, the third largest island in the world. Some of the other tribes in Sarawak are: the Kayan, Kenyah, Kejaman, Kelabit, Punan Bah, Tanjong, Sekapan, and the Lahanan. Collectively, they are referred to as Dayaks or Orangulu which means «people of the interior».[44]

About half of Sarawak’s 1.5 million people are Dayaks. Most Dayaks, it is believed by anthropologists, came originally from the South-East Asian mainland. Their mythologies support this.

Deforestation

Tropical and temperate rainforests have been subjected to heavy legal and illegal logging for their valuable hardwoods and agricultural clearance (slash-and-burn, clearcutting) throughout the 20th century and the area covered by rainforests around the world is shrinking.[45] Biologists have estimated that large numbers of species are being driven to extinction (possibly more than 50,000 a year; at that rate, says E. O. Wilson of Harvard University, a quarter or more of all species on Earth could be exterminated within 50 years)[46] due to the removal of habitat with destruction of the rainforests.

Another factor causing the loss of rainforest is expanding urban areas. Littoral rainforest growing along coastal areas of eastern Australia is now rare due to ribbon development to accommodate the demand for seachange lifestyles.[47]

Forests are being destroyed at a rapid pace.[48][49][50] Almost 90% of West Africa’s rainforest has been destroyed.[51] Since the arrival of humans, Madagascar has lost two thirds of its original rainforest.[52] At present rates, tropical rainforests in Indonesia would be logged out in 10 years and Papua New Guinea in 13 to 16 years.[53] According to Rainforest Rescue, an important reason for the increasing deforestation rate, especially in Indonesia, is the expansion of oil palm plantations to meet growing demand for cheap vegetable fats and biofuels. In Indonesia, palm oil is already cultivated on nine million hectares and, together with Malaysia, the island nation produces about 85 percent of the world’s palm oil.[54][unreliable source?]

Several countries,[55] notably Brazil, have declared their deforestation a national emergency.[56] Amazon deforestation jumped by 69% in 2008 compared to 2007’s twelve
months, according to official government data.[57]

However, a January 30, 2009 New York Times article stated, «By one estimate, for every acre of rainforest cut down each year, more than 50 acres of new forest are growing in the tropics.» The new forest includes secondary forest on former farmland and so-called degraded forest.[58]

Rainforests are the oldest living ecosystems and without a shadow of a doubt, the most vital habitats on Earth. They cover only 6% of the Earth’s surface but yet they contain more than half of the world’s plant and animal species. According to the current estimates, around 40% to 75% of all biotic species are indigenous (see notes 1) to the rainforests.

What’s more, there are probably millions of species of plants, insects, and microorganisms still undiscovered in tropical rainforests. They are responsible for 28% of the world’s oxygen turnover. More than 20% of the world’s oxygen is produced in the Amazon Rainforest only, that’s why it has been described as the “lungs of our planet”.

Unfortunately, rainforests are rapidly disappearing due to deforestation. The loss is huge, and probably hundreds or even thousands of undiscovered species going extinct every single day. We are losing them forever.

What is Rainforest?

A Rainforest can be described as a tall, dense jungle. They get a really high amount of rain per year, hence the name. Annual rainfall in the case of tropical rainforests between 250 and 450 cm (98-177 in), and definitions varying by region for temperate rainforests.

The Congo rainforest is the second-largest rainforest in the world (after the Amazon rainforest). At 500 million acres, it is larger than the state of Alaska. There are approximately 10, 000 species of tropical plants in the Congo Basin and 30 percent are unique to the region. The lush forests are inhabited by endangered wildlife, including forest elephants, chimpanzees, bonobos, and lowland and mountain gorillas. 400 other species of mammals, 1,000 species of birds, and 700 species of fish can also be found there.

The Congo Basin forests are a lifeline for more than 60 million people — providing food and income for many remote communities, storing huge amounts of carbon, supporting unique ecosystems, and regulating the flow of the major rivers across Central Africa.

Southeast Asian Rainforests

The third-largest rainforests on Earth, the Southeast Asian rainforests are the oldest, consistent rainforests on Earth, dating back to the Pleistocene Epoch 70 million years ago.  They are also thought to be the most biologically diverse ecosystems on Earth: their biological richness and diversity are unequaled by that of the Amazon or African rainforests. Unfortunately, they are shrinking much faster than any other rainforest in the world – they will be completely destroyed in around ten years.

Valdivian Temperate Rainforest

Named after the Chilean city of Valdivia, the Valdivian template rainforest lies on the west coast of southern South America, in Chile, and extends into Argentina. It includes stands of huge trees, especially Nothofagus and Fitzroya, which can live to a great age. Some of the threatened mammals of the rainforest include the monito del monte (Dromiciops gliroides), an arboreal marsupial, and the southern pudú (Pudu pudu) the world’s smallest deer, and the kodkod (Leopardus guigna), South America’s smallest cat.

Tongass National Forest

The largest national forest in the United States at 16.7 million acres (68,000 km2), the Tongass National Forest in Southeast Alaska is the largest national forest in the United States. Most of its area is part of the temperate rainforest WWF (see notes 2, 3) ecoregion, itself part of the larger Pacific temperate rainforest WWF ecoregion, and is remote enough to be home to many species of endangered and rare flora and fauna.

Tongass National Forest is the largest forest in the United States.

Daintree Rainforest

The rainforest is named after Richard Daintree, the Australian geologist, and photographer (1832-1878). The Daintree is a part of the largest continuous area of tropical rainforest on the Australian continent. Its tropical rainforest ecosystem is one of the most complex ecosystems on Earth.

Kinabalu National Park

It is Malaysia’s first World Heritage Site designated by UNESCO in December 2000 (see Top 20 Countries having the most number of UNESCO World Heritage Sites). With more than 4,500 species of flora and fauna, including 326 bird and around 100 mammal species, and over 110 land snail species, Kinabalu Park is one of the most important biological sites in the world.

Notes

  1. Indigenous generally refers to people who have lived in a place or country for a very long time. Also known as natives, Indigenous people are ethnic groups who are the original inhabitants of a given region, in contrast to groups that have settled, occupied, or colonized the area more recently. In biogeography, a species is defined as indigenous to a given region or ecosystem if its presence in that region is the result of only natural processes, with no human intervention. In other words, indigenous is living organisms (plants, animals, insects, etc.) that developed in a place rather than arriving from somewhere else. The word indigenous comes from the Latin ‘indigena’ meaning ‘a native’ and was developed in mid-17th century English to carry the meaning it now holds.
  2. There are two types of rainforests: tropical, and temperate. Tropical rainforests (i.e. Amazon rainforest) are typically found within 10 degrees north and south of the equator and are characterized by a warm and wet climate with no substantial dry season. Temperate rainforests, as their name suggests, are rainforests in temperate regions. Tropical forests cover much larger areas than temperate rainforests.
  3. The World Wide Fund for Nature (WWF) is an international non-governmental organization founded in 1961, working in the field of wilderness preservation, and the reduction of human impact on the environment.

Rainforests have been around for millions of years and contain over half of all living things in the world. Located near to the equator, they have remained in place even during the ice ages and have had a prolonged period of time to develop and become incredibly specialised. A common misconception is that the abundant wildlife means the soil must be good but this is often not the case.

   6.   The trees are so densely packed that rain can take 10 minutes to reach the ground after hitting the canopy. 

   7.    The soil in rainforests is actually thin and quite poor. The plants have had millions of years to evolve to get used to the poor soil conditions.

The high rainfall leads to large surface runoff which leads to large rivers. There are many large rivers in rainforest areas.

Tropical rainforests are found in areas of heavy rainfall mostly close to the equator. Temperate rainforests are found in areas of heavy rainfall close to the coast. This map shows the location of the wolrd’s rainforests. For more rainforest maps, click on the link below.

Rainforest people

The rainforests are home to many tribes of indigenous people that make their livelihoods from the rainforest in a sustainable way. 

Some examples of indigenous groups that live in rainforest regions include: The Yanomami of Brazil, the Penan of Sarawak, and the Desana of Columbia.

Rainforest layers

rainforest layers

There are four layers of plants in the rainforest. These are:

  • The emergent layer

  • The canopy

  • The understory and

  • the undergrowth. 

There are animals that only live in the canopy for example and similarly, animals that only live in the undergrowth. 

Similiarly, there are plants which don’t even have their roots in the soil. Lianas are a vine like plant that get all their water from the rainfall. 

Deforestation

  • Deforestation is when the trees are chopped down.

  • They are mostly chopped down for farming. 

  • Rainforests used to cover 14% of all the land in the world, now they cover only 6% of the land.

  • Every second, an area the size of a football field is chopped down. 

  • Copping down trees is hard work so the forest is often set on fire to clear the land. 

Rainforest climate

equatorial climate graph | rain forest climate graph | amazon rainforest climate

Tropical rainforests have pretty much the same weather every day. They are near to the equator so it is hot all year round. That means that there is no winter, or autumn or spring for that matter. 

They experience heavy rainfall throughout most of the year. 

Temperate rainforests are different in that they still have rain all year round but they are cooler. 

Rainforests help to balance the world. They help in various ways in our life. By reading this, you will know the Top 10 Largest & Popular Rainforests in the World.

Let’s start,

What is Mean by Largest Rainforests in the World?

Top 10 Largest and Popular  Rainforests in the World

A rainforest is a region with thick, evergreen trees and high rainfall. Rainforests are high and constant precipitation forests with annual precipitation between 2.5 and 4.5 meters (98 and 177 in) for rainforests, and region-based definitions differ in tempered precipitation forests.

The monsoon trough also called the intertropical convergence zone, plays a major role in establishing the requisite climate conditions for the world’s tropical rainforests: different from the monsoonal areas of the tropical seasonal forests.

Estimates range from 40% to 75% of all biotic species in tropical rainforests. There could still be several million Undiscovered plant species, insects, and microorganisms. Rainforests are responsible for 28 percent of the planet’s turnover, sometimes misnamed oxygen production, [4%] by managing them through carbon dioxide photosynthesis and breathing. Rainforest is the world’s biggest pharmacy since more than one-quarter of natural drugs have now been identified.

Sunlight can be poorly penetrated to the ground in some parts of the rainforest. The soil below is soon colonized by a thick, tangled growth of vines, shrubs, and small trees, known as jungles when the leaf canopy is lost or thinned. In tropical rainforests, the word jungle is also sometimes used.

What are the Importances of the Largest Rainforests in the World?

Top 10 Largest and Popular  Rainforests in the World

There are many explanations for the importance of rainforests under the following headings:

1. Survival

The absorption of carbon dioxide and the release of oxygen depends on our survival. Adding this carbon dioxide helps balance the atmosphere of the Planet.

Regenerated forests help to keep the world’s water cycle working through the perspiration process, which generates clouds, adding water to the environment. The waters created in rainforests travel worldwide; scientists believe that humidity in Africa’s forests is dropping in America!

2. Biological diversity

Rainforests have nearly half of the current world species of plants and animals. It comprises one-third and 90 percent of the world’s bird species. There are more animals and plant species in African rainforests than anywhere on the continent. 19 new lemur species were officially reported in Madagascar within just one year in 2006.

3. Medicines

Modern medicines use hundreds of rainforest plants. It is estimated that 25% of all our medicines come from rainforest plants. Vincristine, for example, has allowed certain types of childhood leukemia to recover 80% from a drug taken in the rosy periwinkle of Madagascar.

Curare is a muscle-relaxant poison used by Indians of the Amazon in arrow tips when given in small quantities. Only about 1% of the plant species have been examined, meaning many more diseases could be identified.

3. Canopy

There is a canopy for all rainforests. This is a stratum of branches and leaves on the highest trees. The canopy can be about 100 feet above the ground or above. The canopy is not the soil where most plants and animals live.

And what a live set! Scientists agree that nearly half of the Earth’s plants and animals live in rainforests. Many of them are vulnerable and can survive only in this habitat.

4. Regeneration and rainforests

The plants and their release into the air through leaves, stems, and flowers contribute to the rainfall through transpiration, the mechanism of water movements. As a by-product of photosynthesis, plants release water. Farm water contributes to local moisture or humidity in the air.

Because the forest consists of several trees, volumes of water released through transpiration will lead to rainfall, and wide rainforests like the Amazon can drive big precipitation. It is estimated that the Amazon is responsible for 70% of the rainfall in Southern Brazil.

Amazon Rainforest Weather and Climate Facts | Guide

Due to the implications of anthropogenic activities of deforestation and destruction, rainforests have faced significant challenges over the last few decades.

The planet still has a lot of incentive to consider and conserve the current rainforests, particularly amid such environmental problems. This article looks at the 10 largest and most common rainforests in the world.

1. Forest of the Amazon (South America)Largest Rainforests in the World

Top 10 Largest and Popular  Rainforests in the World

It is also called the Amazon Jungle or Amazon Rainforest, the largest tropical rainforest in the world.

It occupies much of the South American Amazon Basin, covering Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guiana, Surinam, and French Guiana, with 5,500,000 sq km of surface space. The river Amazon also crosses the forest. In Brazil, there is about 60 percent of the forest.

2. The Republic of Congo (Africa)

Top 10 Largest and Popular  Rainforests in the World

Congo’s rainforest is the second largest in the world, occupying 1,780,000 square kilometers. It is located in Central Africa and has one of its longest rivers. The rainforest spreads over a wide region of Northern Congo.

The Congo River is, by the amount of 3,7 million square kilometers, the second largest river in the world, known as the Congo Basin.

3. Australiasia

Top 10 Largest and Popular  Rainforests in the World

The Australiasia rainforest contains tropical forests in the island of New Guinea and northeast Australia and dispersed islands linked by a single soil mass as the sea level decreased during the last ice age.

Almost all of the largest tropical rainforest in this region is found on the island of New Guinea, which is roughly divided between Indonesia and Papua N.G.

New Guinea, with around 800 languages, is the world’s most linguistically rich island. In remote parts of New Guinea, there are reportedly some uncontacted communities.

4. Sundaland

Top 10 Largest and Popular  Rainforests in the World

Sundaland contains, among others, the islands of Borneo, Sumatra, Java, and the Malaysian Peninsula. Most of the region’s remaining forests are on Borneo Island, which is split politically between Indonesia, Malaysia, and Brunei.

Between 2002 and 2019, Sundaland lost the largest share of the world’s primary forest cover. Borneo has lost 15% of those forests, and Sumatra has lost 25%.

5. Rainforest in Southeast Asia

Top 10 Largest and Popular  Rainforests in the World

These forests were once the most biodiverse areas in the world, extending from India to Malaysia until much land was cleared for logging and farming. Most rainforests in Asia are spread throughout the Indonesian islands. Experts say Malaysia’s rainforests existed 100 million years ago.

6. New Guinea rainforest

New Guinea rainforest

New Guinea’s rainforests comprise about 65 percent of the world’s second-largest island. The island is the home of Asia-largest Pacific rainforest and the world’s third-largest rainforest.

The richness of the New Guinea Rainforest is in competition with few areas on Earth. The island is home to some of the world’s most diverse plants and wildlife, from thick tropical rainforests to coastal mangroves. There are more orchid species here than anywhere else on Earth.

7. Valdivian rainforest

Valdivian rainforest

The world’s southernmost jungle is known as rainforest at the end of the globe, and it is found on the western side of southern South America, Selva Valdiviana (Valdivian Temperate Forest).

The forest occupies a small continental stretch between the west slopes of the Andes and Pacific Oceans. It is the world’s largest temperate rain forest, with thick collections of ferns, bamboo, and annual angiops dominating the landscape.

8. The Island of Borneo

The Island of Borneo

The Borneo Island rainforest is believed to be about 140 million years old and to be one of the oldest rain forests in the world, and is the third largest island in the world.

It is a mixture of lowland and montane rainforest over 1.000m, known as the last wide Asian rainforest (3,300ft). Especially due to harvesting, hunting and conversion to the commercial land use the Borneo lowland rainforest declined so much that in 2007 WWF launched the Heart of Borneo Initiative to save one of the largest rainforests in the world.

9. Sinharaja rainforest

Sinharaja rainforest

The Sinharaja is a rain forest of tropical lowlands which was declared a World Biosphere Reserve in 1978 to protect it from deforestation and other harmful activities.

This rainforest is filled with all kinds of endemic animals, including the region’s reptiles, birds, and unique mammals. The Sinharaja is also known for being unbelievably small and just 14 miles’ diameter apart from being a diverse and rich rain forest.

10. The Daintree Rainforest

The Daintree Rainforest

Although it’s not the world’s biggest rainforest, Daintree is also considered as one of the most beautiful rainforests with its tree line to the ocean’s edge, with hundreds of ancient species, including an old coniferous trees which are dozens of meters.

Most of the Daintree forest was declared a World Heritage Site for wet tropics in 1988 and protected from various artificial problems, such as logging. A significant percentage of Australia’s animal species containing more than 65% of its butter and bat species is found in this forest.

How to Protect the Largest Rainforests in the World?

How to Protect the Largest Rainforests?

1. Lower the usage of paper and wood

To manufacture wood and paper items such as office paper, phone books, toilet paper, window trim, lawn furniture, and 2 x 4’s, logging companies are decoupling some of the world’s most endangered forestry. About 78% of the original old-growth forests on Earth have either been logged or degraded.

By taking easier measures to minimize the use of wood and paper you will reduce the burden on the rest of the forests.

2. Clean Air

Natural air filters are rainforests. Excess carbon and other air pollutants are processed and filtered and oxygen is released by photosynthesis. Our world cannot offset excess greenhouse gas emissions without rainforests, destabilizing the Earth’s atmosphere.

3. Eat less meat – or give it up

Cattle ranching accounts for about 80% of deforestation in the Amazon. In Brazil, ranchers and farmers began to clear grassland for their livestock.

It’s a clear case of supply and demand. As people eat more beef, farmers must raise additional cows, thereby making more room for the livestock possible.

4. Support indigenous communities

The purchasing by local citizens of arts and fair trade goods is a unique and productive way to conserve rainforests and livelihoods sustainably.

Know who you want to purchase to ensure that you do not unwittingly help businesses with cultural appropriations.

5. Spare your time

It can make a huge difference to devote your personal energy and time. Will you spend 1-2 hours a week or 5-10 hours? Supporting our mission, the Rainforest Foundation USA accommodates voluntary workers with varied experience and talents.

Your dedication and time will enable us to advance our vision of a future where majestic rainforests of the earth flourish forever, from translations, editing, and video production.

FAQ Session on Largest Rainforests in the World

Top 10 Largest and Popular  Rainforests in the World

  1. What should we do for rainforest protection?

    Eliminate your diet’s deforestation.
    Buy Sourced Goods Responsibly.
    Choose goods to return.
    The Indigenous Peoples are to be supported.
    Reduce your footprint for carbon.

  2. How do people ruin the rainforest?

    Deforestation is the second biggest cause of climate change, accounting for 18-25% of global annual carbon dioxide emissions (more than the whole world transport sector). Deforestation is induced directly by humans, including forestry, cattle farming, mining, oil extraction, and construction.

  3. What is at risk for the Largest Rainforests in the World?

    Interest in logging decreases rain forestry trees for wood used for floors, furnishings, and other items. Power stations and other factories are chopping down and burning energy trees. The paper sector transforms large stretches of plum trees into pulp.

  4. How can rainforests be prevented?

    We can all be part of the campaign to conserve forests by less consumption, avoiding single-use packaging, consuming organic foodstuffs, and preferring recycled or responsible wood products. Choose and do so vocally for trees, nature, and people!

  5. Why shouldn’t the rainforest be cut down?

    The plants and animals that live in the woods are killed, and certain species are in danger of becoming extinct when those forests are cut off. The rainforests are required for oxygen production and for purifying the atmosphere to help us respire. We also know that the Earth’s atmosphere and the water cycle can be influenced.

Conclusion about Largest Rainforests in the World

The Amazon, as the largest rainforest in the world, is vital to our planet’s health. It provides almost 20% of our earth’s oxygen, sends a large amount of water into the air, and takes up over 2.2 billion tons of carbon dioxide annually.

Amazon Rainforest’s survival is vital to our survival, but not just because we should protect it. It’s necessary. More than 300,000 indigenous people in the Amazon have territories that comprise 23% of the Amazon region. The loss of their property constitutes a major violation of fundamental human rights.

The fires in the Brazilian rainforest made headlines last month when the world discovered this issue. Although it can look like something out of your control, our regular acts have more impact than you may realize.

An aerial view of the Amazon rainforest, the world’s biggest rainforest.

Nature is beautiful. Being surrounded by greenery and towering trees instills a sense of peace and majesty that can’t be matched by many things in life. High on this list of serene beauty are rainforests, some of Earth’s oldest living ecosystems. 

These amazing densely habituated areas cover only 6% of the world’s surface but contain more than half of the species of plants and animals on this planet. This perfectly illustrates how important and varied they are.

Compared to other forested areas, they are unique for their climate, specifically the amount of water they receive in a given year. This stand-out aspect also means that the animals and botany within must adapt to the environment, and as a result, it’s possible to see many specialized organisms that couldn’t exist anywhere else. If you ever have the chance, the world’s rainforests are a must-visit locale.

What Is A Rainforest?

A rainforest is defined by the fact that it contains many large evergreen trees that never lose their leaves, and by the high amount of rainfall it receives. Specifically, to be classed as a rainforest, the area must receive continuous and heavy rainfall, reaching a range of between 98 and 177 inches in a year. 

However, definitions can vary by region with temperate rainforests also being classed by the temperature they are, with an expected mean annual temperature of between 39 and 56 degrees Fahrenheit. 

These ecological dreams are have been around for millions of years, with some of the older ones existing since at least 70 million years ago. They are complicated systems filled with diverse wildlife and once dominated 14% of the world’s surface, though they now only cover a third of that area. 

Some important rainforest facts. Image credit: SaveJungle/Shutterstock.com

In fact, a single 4-square-mile patch of rainforest can have up to 1,500 blooming plants, 750 variations of trees, 400 species of birds, and 15 classes of butterflies.

Even now, it is estimated that millions of different types of insects, plants, and microorganisms remain undiscovered within the leafy boughs of these rainforests.

This extreme biodiversity is critical to the health of humans and the planet. On top of helping to control the currently unstable climate, they also produce a variety of everyday products like chocolate, sugar, and certain medicines. Rainforests have sometimes been referred to as the world’s largest pharmacy because over 25% of natural medicines have been discovered in this area.

However, overly ambitious industrial and agriculture processes have contributed to damaging the health of rainforests, with many organizations and individuals springing up to form groups dedicated to preserving these essential but easily disrupted zones. 

This is important too, as rainforests are responsible for a solid 28% of the world’s oxygen turnover, pulling out large amounts of carbon dioxide from the air, which would otherwise contribute to the greenhouse warming effect currently happening across the globe.

Rainforests are also often dimly light, with undergrowth—meaning the vegetation in the lower area of the forest—often blanketing out the sun and causing there to be minimal illumination at the ground level. In some cases, if the canopy of leaves is reduced or destroyed, the ground beneath can soon become taken over by a dense and intricate tangle of vines, shrubs, and small trees, forming what is known as a jungle.

Sometimes the term «jungle» is used to apply to tropical rainforests overall. 

The Layers Of A Rainforest

Most rainforests are split up into four distinct layers. Each of these parts is defined by a unique set of characteristics that vary based on levels of sunlight, air circulation, and water. This article will go through them from the top down.

These elements are :

  1. Emergent Layer
  2. Canopy Layer
  3. Understory Layer
  4. Forest Floor

1. Emergent Layer

The outermost layer of the rainforest is the emergent layer. Here it is where the massive trees, sometimes stretching up to 200 feet, control the skyline. Foliage on the tree trunks tends to be minimal and thin but spread wide as the trees reach their sunny upper layer, where they can properly absorb nutrition from the light of the sun. 

Smaller, waxy leaves in the emergent layer help the trees to hold on to water during long dry periods or seasons with minimal rain. As well, small seeds on this layer are exposed to strong winds that help carry them away to propagate elsewhere.

The emergent layer is filled with flying and gliding animals, or otherwise small creatures that can rest on the thin layers up top. These include bats, birds, butterflies, and gliders.

2. Canopy Layer

Below the emergent layer is the canopy layer, a deep area, that is approximately 20 feet thick. This interconnected network of branches and vegetation forms a sort of roof over the remaining layers.

The canopy excludes wind, rainfall, and sunlight, in the process creating a moist, quiet, and poorly light environment below. Trees in this layer feature glossy leaves with sharp tips that repel water. 

Since this layer can’t rely on wind to blow away its seeds, fruit is much more common. These sweet food items attract animals who eat them and then discard their seeds across the forest floor. Because of food availability, more animals can be found here than anywhere else in the entire rainforest.

3. Understory Layer

Next is the understory layer, several feet further down from the canopy. It’s even darker, increasingly humid, and much quieter. 

Plants here have larger leaves, a requirement to catch the reduced amount of sunlight that gets to this layer. The plants here also tend to feature large and bright flowers, like the strong-smelling orchids. As a result, they attract pollinators who can help spread their seed.

Many animals in this area take advantage of the dim lighting for camouflage.

4. Forest Floor

The last layer is the forest floor. It is the least lit of all the areas, with few plants and quickly decaying leaves. It’s here where decomposers like slugs, worms, and other creepy crawlies can be found.

Certain animals also like this region as an area to forage for insects, with these insect-eaters hunted by larger predators like jaguars.

As a result of rivers running through the area, the forest floor can feature unique freshwater habitats. For instance, the pink river dolphin, a species which is one of the few known freshwater dolphins in the entire world. 

Where Are Rainforests Found?

Rainforests can be found basically everywhere except Antarctica. The largest ones on this planet are situated near the famous Amazon River in South America and the Congo River in Africa. As well, scientists have found the balmy islands of Southeast Asia and portions of Australia to be ideal regions for the type of climate required to house and sustain these ecosystems. Colder rainforests can be found in America’s northwest region, and even in the north of Europe.   

The monsoon trough, otherwise referred to as the intertropical convergence zone, is an area where winds from the north and south meet, creating heavy winds and rainfall. This area plays a key role in maintaining the conditions needed to continue the existence of the Earth’s tropical rainforests.  

The two types of rainforests, tropical and temperate, vary in their location. Tropical forests are found in a band around the equator, between the Tropics of Capricorn and Cancer. Temperate rainforests, on the other hand, are found stretched across the pacific coast of the USA and Canada as well as in the United Kingdom, Chile, Tasmania, New Zealand, and Norway. These ecosystems tend to be colder, though they remain just as humid as their tropical counterparts. 

The Amazon Rainforest is the Earth’s most massive tropical rainforest. The forest spans through the basin of the previously mentioned Amazon river (which itself is the world’s second-longest river) and houses about 20% of the planet’s plants and birds, with 10% of mammal types found there.

The African Rainforests, on the other hand, are found near Central Africa and come in as the second-largest tropical ecosystems in the world. The neighboring area of Madagascar was once heavily forested but through human expansion, it has mostly disappeared. Africa still holds many zones of high cloud forest, flooded forests, and mangrove swamps. 

The Asian Rainforests, go all the way from western India and Burma to the Borneo and Java islands in the eastern region. Bangladesh has the highest concentration of mangrove forests, globally. The location of these rainforests in this area makes sense given how hot and humid Southeast Asia can be. Mainland Asia features a close to tropical climate, that varies between heavy and fierce monsoon rains and dryer, parched periods.

Lastly, there are the Australasian Rainforests. This continent once consisted of Australia, New Guinea, and New Zealand, millions of years ago, entirely cut off from the rest of the world. This area was heavily forested. Today these countries, though split, still have various different species of animals, several of which are uniquely contained to this area online. Typically, undergrowth in Australia’s tropical forests is thick and dense. They also are situated right in the corridor where humid winds come in from the Pacific. 

Types Of Rainforests

There are two main types of rainforests to consider, with each type sufficiently varied in climate, location, and prevalence of certain plants and animal species. 

These are:

  • Tropical Rainforests
  • Temperate Rainforests

Tropical Rainforests

Tropical rainforests are mainly located between the Tropics of Cancer and Capricorn, otherwise known as the tropics area. These include forests in western India, Southeast Asia, Central and South America, the island of New Guinea, and western and central Africa.

These rainforests can contain a top layer of a canopy featuring giant trees that grow. up to staggering heights of 250 feet or more. This uppermost layer prevents too much sunlight from reaching the ground, encouraging the growth of thick, ropey vines. Many of the plants in this biome have been used as common houseplants, as they require minimal sunlight and rain, and can grow in any condition.  

In these forests, sunlight tends to come in at a direct, harsh angle, producing a lot of solar energy that maintains a very high temperature in these regions. This temperature can range, typically, from 70 to 85 degrees Fahrenheit.

As a result of these high temperatures, the air is kept at a very humid and hot level, with humidity reaching averages of 77% to 88%. Basically, any humans visiting will be sweating constantly and likely wishing to be free of the muggy, deeply uncomfortable, and bug-infested climate.

The humid air has another knock-on effect on the surrounding weather patterns. Rainfall is the norm, coming down constantly, in frequent bursts of extreme waterfall that verges on monsoon levels of rain. The total rainfall in these regions can range all the way from 80 to 400 inches in a given year, an absolutely towering amount that explains why these rainforests are so aptly named.

Because of the high amounts of sunlight and the rich building blocks of moisture and rain, tropical rainforests house a uniquely diverse range of flora and fauna. It’s so diverse that an approximate number from 40 to 100 different species of trees can be found in each hectare. 

In fact, these rainforests are easily the most terrestrial animal and plant diverse ecological habitats in the entirety of planet Earth. 

The Amazon Rainforest alone contains nearly 1300 types of birds, 3000 fish species, 2.5 million species of insects, 427 different mammals, and around 40,000 plant species. This is only cataloging the ones that have already been found and classified, with millions more estimated to exist in these ecological hotspots.

On the forest floor, animals like the okapi can be found. This stand-out mammal species is native to the tropical climes of the Democratic Republic of Congo in Central Africa. They look like zebras but are in reality more closely tied to giraffes, which makes sense once you see their distinctive faces. They tend to feed on tree leaves, buds, and fungi.

Moving up to the understory layer, animals like the infamous jaguar can be found. Their spots are meant to resemble the interplay of shadow and light peeking through the dense canopy, providing them with a built-in camouflage perfect for stalking and capturing their prey. They can typically be found across Central America and in portions of Paraguay and Argentina. They even extend out to Mexico. This is a distinctive, solo, top of the food chain predator that dominates the ecosystems it inhabits.

In the canopy layer, cuter animals can be found like spider monkeys in South and Central America and keel-billed toucans in Latin America. The toucans like to roost in tree holes prevalent throughout this layer and they often like to tuck their beaks and tails under their bodies. Spider monkeys are highly social and live in groups of 30+ individuals.

Lastly, on the emergent layer, only the smallest and flightiest of animals can be found. The crowned eagle is one such animal. It is a bird of prey that mainly feeds on animals like primates and lizards. It’s a massive bird and ferocious in its hunting patterns — an arbiter of death that is likely the last thing many creatures see before they die.

As for leaves and plants, these tropical rainforests feature many thousands of broad-based leaves at an age of between 50 and 100 years. At the bottom-most layers, decomposition is frequent. 

Temperate Rainforests

Temperate rainforests mainly vary from tropical rainforests in where they are located. However, as a result of this difference, they actually branch off into completely unrecognizable paths, with a drastically altered climate, and endemic wildlife that is in a completely different sphere of existence.

First, this article will go over its location. Temperate rain-forests are located in the mid-latitudes, an area on earth defined as the zone between the latitudes of 23, 26, 22 and 66, 33, 39 north, and 23, 26, 22 and 66, 33, 39 south. This region features temperature and climates that are much milder than the tropics, and as a result, are considerably more comfortable and accessible for human habitation.

To narrow down the region, even more, temperate rainforests are typically found in mountain-filled areas, located along coasts. This location is critical because these geographic circumstances help to encourage the heavy and frequent rainfall associated with any rainforest.

As for national borders, temperate rainforests can be found along the sealines of the Pacific Northwest in North America, Norway, Japan, southern Australia, New Zealand, Chile, and the United Kingdom.

The name aptly describes their main difference from tropical rainforests. Specifically, that they are much more temperate and comfortable to visit. They’re considerably cooler than their tropical counterparts, hitting an average of 50 degrees Fahrenheit to 70 degrees Fahrenheit over any given rain. They are also a lot less sunny and have considerably less rainfall. In fact, they only receive 60 to 200 inches of rain per year, a figure that is half of the tropical rainfall levels at their respective peaks.

Still, the rainfall is higher than many other areas in the world, and this is largely a result of the coastal location. Moist, hot air from the coastal bodies of water push in and become trapped against the nearby mountains. As a result, the conditions for rain are created. 

Because of these weather conditions, not as much wildlife can grow and truly prosper, as they can in tropical regions. Temperate rainforests are generally not as biologically diverse as their hotter, more humid cousins, but they have advantages of their own.

Specifically, they host an astounding quantity of biological processes and productivity, with a total storage of up to 500-2000 metric tons of wood, leaves, and other varied organic matter per hectare.

This is possible because the cooler temperatures and less fluctuating climate slow down the processes of decomposition, allowing more material to gather over time. As an example, look at the Pacific Northwest’s old-growth forests, which produce three times the biomass (which refers to material that is living or was once living) of comparable tropical rainforests.

This heavy density of dead and living material means that many plant species can thrive in a never before seen way. As a result, they can often live for longer and grow to even more enormous dimensions than are seen in the tropics. For instance, temperate rainforest trees like the redwood coast in the United States’ California, and Chile’s alerce, rank among the biggest and most long-living species of tree in the entire world.

As for the animals, it’s common to see much more large mammals, though small birds, reptiles, and insects are also common.

Black bears and bobcats are two such apex predators in this area. The black bear is a moderately sized creature, thickset and bulky in its composition. It uses its strong curved claws to tear out roots, logs, and stumps when foraging for food. Meanwhile, bobcats may look like their sister felines, but they are in fact ferocious predators capable of leaping up to 12 feet to capture their prey.

On the smaller side of things, these regions house unique ground and sky dwellers. Chile’s rainforests have birds like the Juan Fernández firecrown, a color-changing hummingbird, and the Magellanic woodpecker. Australia is home to creatures like wallabies and bandicoots. They are also the resident habitat of potoroos, adorable small marsupials that currently rank as one of the most endangered animals in the entire region.      

Protecting The World’s Rainforests

There is so much to learn about rainforests that even the world’s top scientists and animal scholars have yet to unearth all there is to know about these humid and hot ecosystems. 

From their unique characteristics of heavy rainfall and warm temperature to their varied animal life, rainforests really are a unique ecological habitat that will be hard to replace.

That’s why it’s important than ever to focus on preservation efforts. Human activity has threatened these majestic sites, and though efforts are being made to reverse these impacts, it may be too little too late.

Losing the rainforests would have dramatic effects on global species diversity, carbon dioxide production, and temperature regulation. Next time you hear about global warming, keep in mind the animals and plants that are still out there to save.
