Rainforests are forest ecosystems characterized by high levels of rainfall, an enclosed canopy and high species diversity. While tropical rainforests are the best-known type of rainforest and the focus of this section of the web site, rainforests are actually found widely around the world, including temperate regions in Canada, the United States, and the former Soviet Union.
Tropical rainforests typically occur in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn, latitudes that have warm temperatures and relatively constant year-round sunlight. Tropical rainforests merge into other types of forest depending on the altitude, latitude, and various soil, flooding, and climate conditions. These forest types form a mosaic of vegetation types which contribute to the incredible diversity of the tropics.
The bulk of the world's tropical rainforest occurs in the Amazon Basin in South America. The Congo Basin and Southeast Asia, respectively, have thesecond and third largest areasof tropical rainforest. Rainforests also exist on some the Caribbean islands, in Central America, in India, on scattered islands in the South Pacific, inMadagascar, in West and East Africa outside the Congo Basin, in Central America and Mexico, and in parts of South America outside the Amazon. Brazil has the largest extent of rainforest of any country on Earth.
Rainforests provide important ecological services, including storing hundreds of billions of tons of carbon, buffering against flood and drought, stabilizing soils, influencing rainfall patterns, and providing a home to wildlife and Indigenous people. Rainforests are also the source of many useful products upon which local communities depend.
While rainforests are critically important to humanity, they are rapidly being destroyed by human activities. The biggest cause of deforestation is conversion of forest land for agriculture. In the past subsistence agriculture was the primary driver of rainforest conversion, but today industrial agriculture — especially monoculture and livestock production — is the dominant driver of rainforest loss worldwide. Logging is the biggest cause of forest degradation and usually proceeds deforestation for agriculture.
Organization of this site
The rainforest section of Mongabay is divided into ten "chapters" (the original text for the site was a book, but has since been adapted for the web), with add-on content in the form of special focal sections (e.g. The Amazon, the Congo,REDD,New Guinea,Sulawesi,Forests in Brazil, etc), appendices, and other resources.
There is also a version of the site geared toward younger readers atkids.mongabay.com。
ABOUT THE RAINFOREST (SUMMARY)
Chapter 1:RAINFOREST DISTRIBUTION AND CHARACTERISTICS
每个雨林是独一无二的,但也有证书ain features common to all tropical rainforests.
- Location: rainforests lie in the tropics.
- Rainfall: rainforests receive at least 80 inches (200 cm) of rain per year.
- Canopy: rainforests have a canopy, which is the layer of branches and leaves formed by closely spaced rainforest trees some 30 meters (100 feet) off the ground. A large proportion of the plants and animals in the rainforest live in the canopy.
- Biodiversity: rainforests have extraordinarily highs level of biological diversity or “biodiversity”. Scientists estimate that about half of Earth's terrestrial species live in rainforests.
- Ecosystem services: rainforests provide a critical ecosystem services at local, regional, and global scales, including producing oxygen (tropical forests are responsible for 25-30 percent of the world's oxygen turnover) and storing carbon (tropical forests store an estimated229-247 billion tons of carbon) through photosynthesis;influencing precipitation patterns and weather;moderating flood and drought cycles; andfacilitating nutrient cycling; among others.
The global distribution of tropical rainforests can be broken up into four biogeographical realms based roughly on four forested continental regions: the Afrotropical, the Australiasian, the Indomalayan/Asian, and the Neotropical. Just over half the world's rainforests lie in the Neotropical realm, roughly a quarter are in Africa, and a fifth in Asia.
These realms can be further divided into major tropical forest regions based on biodiversity hotspots, including:
- Amazon: Includes parts of Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Venezuela
- Congo: Includes parts of Cameroon, Central African Republic, Democratic Republic of the Congo, Equatorial Guinea, Gabon, Republic of Congo
- Australiasia: Includes parts of Australia, Indonesian half of New Guinea, Papua New Guinea
- Sundaland: Includes parts of Brunei, Indonesia, Malaysia, Singapore
- Indo-Burma: Includes parts of Bangladesh, Cambodia, China, India, Laos, Myanmar, Thailand, Vietnam
- Mesoamerica: Includes parts of Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama
- Wallacea: Sulawesi and the Maluku islands in Indonesia
- West Africa: Includes parts of Benin, Cameroon, Côte d'Ivoire, Ghana, Guinea, Liberia, Nigeria, Sierra Leone, Togo
- Atlantic forest: Includes parts of Argentina, Brazil, Paraguay
- Choco: Includes parts of Colombia, Ecuador, Panama

RAINFOREST STRUCTURE
雷竞技reybat吧热带雨林的特点是一个独特的vegetative structure consisting of several vertical layers including the overstory, canopy, understory, shrub layer, and ground level. The canopy refers to the dense ceiling of leaves and tree branches formed by closely spaced forest trees. The upper canopy is 100-130 feet above the forest floor, penetrated by scattered emergent trees, 130 feet or higher, that make up the level known as the overstory. Below the canopy ceiling are multiple leaf and branch levels known collectively as the understory. The lowest part of the understory, 5-20 feet (1.5-6 meters) above the floor, is known as the shrub layer, made up of shrubby plants and tree saplings.
RAINFOREST BIODIVERSITY
Tropical rainforests support the greatest diversity of living organisms on Earth. Although they cover less than 2 percent of Earth’s surface, rainforests house more than 50 percent of the plants and animals on the planet.
THE RAINFOREST CANOPY
In the rainforest most plant and animal life is not found on the forest floor, but in the leafy world known as the canopy. The canopy, which may be over 100 feet (30 m) above the ground, is made up of the overlapping branches and leaves of rainforest trees. Scientists estimate that more than half of life in the rainforest is found in the trees, making this the richest habitat for plant and animal life.
The conditions of the canopy are markedly different from the conditions of the forest floor. During the day, the canopy is drier and hotter than other parts of the forest, and the plants and animals that live there have adapted accordingly. For example, because the amount of leaves in the canopy can make it difficult to see more than a few feet, many canopy animals rely on loud calls or lyrical songs for communication. Gaps between trees mean that some canopy animals fly, glide, or jump to move about in the treetops. Meanwhile plants have evolved water-retention mechanisms like waxy leaves.
Scientists have long been interested in studying the canopy, but the height of trees made research difficult until recently. Today the canopy is commonly accessed using climbing gear, rope bridges, ladders, and towers. Researchers are even using model airplanes and quadcopters outfitted with special sensors — conservation drones — to study the canopy.
The rainforest floor
The rainforest floor is often dark and humid due to constant shade from the leaves of canopy trees. The canopy not only blocks out sunlight, but dampens wind and rain, and limits shrub growth.
Despite its constant shade, the ground floor of the rainforest is the site for important interactions and complex relationships. The forest floor is one of the principal sites of decomposition, a process paramount for the continuance of the forest as a whole. It provides support for trees responsible for the formation of the canopy and is also home to some of the rainforest's best-known species, including gorillas, tigers, tapirs, and elephants, among others.

Tropical rainforests support some of the largest rivers in the world, like the Amazon, Mekong, Negro, Orinoco, and Congo. These mega-rivers are fed by countless smaller tributaries, streams, and creeks. For example, the Amazon alone has some 1,100 tributaries, 17 of which are over 1,000 miles long. Although large tropical rivers are fairly uniform in appearance and water composition, their tributaries vary greatly.
Rainforest waters are home to a wealth of wildlife that is nearly as diverse as the biota on land. For example, more than 5,600 species of fish have been identified in the Amazon Basin alone.
But like rainforests, tropical ecosystems are also threatened. Dams, deforestation, channelization and dredging, pollution, mining, and overfishing are chief dangers.

Tropical rainforests have long been home to tribal peoples who rely on their surroundings for food, shelter, and medicines. Today very few forest people live in traditional ways; most have been displaced by outside settlers, have been forced to give up their lifestyles by governments, or have chosen to adopt outside customs.
Of the remaining forest people, the Amazon supports the largest number of Indigenous people living in traditional ways, although these people, too, have been impacted by the modern world. Nonetheless, Indigenous peoples' knowledge of medicinal plants remains unmatched and they have a great understanding of the ecology of the Amazon rainforest.
In Africa there are native forest dwellers sometimes known as pygmies. The tallest of these people, also called the Mbuti, rarely exceed 5 feet in height. Their small size enables them to move about the forest more efficiently than taller people.
There are few forest peoples in Asia living in fully traditional ways. The last nomadic people in Borneo are thought to have settled in the late 2000's. New Guinea and the Andaman Islands are generally viewed as the last frontiers for forest people in Asia and the Pacific.

Every year an area of rainforest the size of New Jersey is cut down and destroyed, mostly the result of human activities.We are cutting down rainforests for many reasons, including:
In recent decades there has been an important shift in deforestation trends. Today export-driven industries are driving a bigger share of deforestation than ever before, marking a shift from previous decades, when most tropical deforestation was the product of poor farmers trying to put food on the table for their families. There are important implications from this change. While companies have a greater capacity to chop down forests than small farmers, they are more sensitive to pressure from environmentalists. Thus in recent years, it has become easier—and more ethical—for green groups to go after corporations than after poor farmers.
Rainforests are also threatened by climate change, which is contributing to droughts in parts of the Amazon and Southeast Asia. Drought causes die-offs of trees and dries out leaf litter, increasing the risk of forest fires, which are often set by land developers, ranchers, plantation owners, and loggers.
Rainforest importance
While rainforests may seem like a distant concern, they are critically important for our well-being. Rainforests are often called the lungs of the planet for their role in absorbing carbon dioxide, a greenhouse gas, and producing oxygen, upon which all animals depend for survival. Rainforests also stabilize climate, house incredible amounts of plants and wildlife, and produce nourishing rainfall all around the planet.
Rainforests:
- Help stabilize the world’s climate: Rainforests help stabilize the world’s climate by absorbing carbon dioxide from the atmosphere. Scientists have shown that excess carbon dioxide in the atmosphere from human activities is contributing to climate change. Therefore, living rainforests have an important role in mitigating climate change, but when rainforests are chopped down and burned, the carbon stored in their wood and leaves is released into the atmosphere, contributing to climate change.
- Provide a home to many plants and animals: Rainforests are home to a large number of the world’s plant and animals species, including many endangered species. As forests are cut down, many species are doomed to extinction.
- Help maintain the water cycle: The role of rainforests in the water cycle is to add water to the atmosphere through the process of transpiration (in which plants release water from their leaves during photosynthesis). This moisture contributes to the formation of rain clouds, which release the water back onto the rainforest. In the Amazon, 50-80 percent of moisture remains in the ecosystem’s water cycle. When forests are cut down, less moisture goes into the atmosphere and rainfall declines, sometimes leading to drought. Rainforests also have a role in global weather patterns. For example researchers have shown thatforests in South America affect rainfall in the United States, while forests in Southeast Asia influence rain patterns in southeastern Europe and China. Distant rainforests are therefore important to farmers everywhere.
- Protect against flood, drought, and erosion: Rainforests have been compared to natural sponges, moderating flood and drought cycles by slowing run-off and contributing moisture to the local atmosphere. Rainforests are also important in reducing soil erosion by anchoring the ground with their roots. When trees are cut down there is no longer anything to protect the ground, and soils are quickly washed away with rain. On steep hillsides, loss of forest can trigger landslides.
- Are a source for medicines and foods and support forest-dependent people: People have long used forests as a source of food, wood, medicine, and recreation. When forests are lost, they can no longer provide these resources. Instead people must find other places to get these goods and services. They also must find ways to pay for the things they once got for free from the forest.
Rainforest conservation
Rainforests are disappearing very quickly. The good news is there are a lot of people who want to save rainforests. The bad news is that saving rainforests will be a challenge as it means humanity will need to shift away from business-as-usual practices by developing new policies and economic measures to creative incentives for preserving forests as healthy and productive ecosystems.
Over the past decade there has been considerable progress on several conservation fronts. Policymakers and companies are increasingly valuing rainforests for the services they afford, setting aside large blocks of forests in protected areas and setting up new financial mechanisms that compensate communities, state and local governments, and countries for conserving forests. Meanwhile, forest-dependent people are gaining more management control over the forests they have long stewarded. Large international companies are finally establishing policies that exclude materials sourced via deforestation. People are abandoning rural areas, leading to forest recovery in some planes.
But the battle is far from over. Growing population and consumption means that rainforests will continue to face intense pressures. At the same time, climate change threatens to dramatically alter temperatures and precipitation patterns, potentially pushing some forests toward critical tipping points.
Thus the future of the world's rainforests in very much in our hands. The actions we take in the next 20 years will determine whether rainforests, as we currently know them, are around to sustain and nourish future generations of people and wildlife.

Can digital twins help save the Amazon? (commentary)(Nov 2 2023)
- Spread across highland forests, tropical steppes, and low-lying floodplains — all of which are affected by varying degrees of human influence — the Amazon is a complex ecosystem. Yet, it remains inadequately mapped.
- Considering the degree of threat facing the Amazon and its global importance, it is critical that to develop better methods for monitoring and comprehending this ecosystem.
- Carlo Ratti, the director of MIT’s Senseable City Lab, and Robert Muggah, the co-founder of the Igarapé Institute, argue that creating a “digital twin” of the Amazonian ecosystem could potentially serve as a means to aid its preservation while fostering a regional bioeconomy.

Critical questions remain as carbon credit deal in Sabah presses forward(Nov 1 2023)
- Details around a secretive “nature conservation agreement” signed in 2021 between a Singaporean company and the government of Sabah, a Malaysian state on the island of Borneo, remain elusive.
- Several internationally known companies that work in climate mitigation have said they’re not affiliated with the agreement, despite implications by Jeffrey Kitingan, a deputy chief minister and the deal’s primary backer, that they are involved.
- Kitingan also revealed that Hoch Standard, the Singaporean company, is controlled by a single director through another company registered in the British Virgin Islands.

Conservationists look to defy gloomy outlook for Borneo’s sun bears(Oct 31 2023)
- Sun bears are keystone species, helping sustain healthy tropical forests. Yet they’re facing relentless challenges to their survival from deforestation, habitat degradation, poaching and indiscriminate snaring; fewer than 10,000 are thought to remain across the species’ entire global range.
- A bear rehabilitation program in Malaysian Borneo cares for 44 sun bears rescued from captivity and the pet trade and has been releasing bears back into the wild since 2015. But with threats in the wild continuing unabated, success has been mixed.
- A recent study indicates that as few as half of the released bears are still alive, demonstrating that rehabilitation alone will never be enough to tackle the enormous threats and conservation issues facing the bears in the wild.
- Preventing bears from being poached from the wild in the first place should be the top priority, experts say, calling for a holistic approach centered on livelihood support for local communities through ecotourism to encourage lifestyles that don’t involve setting snares that can kill bears.
Report alleges APP continues deforestation 10 years after pledge to stop(Oct 31 2023)
- A new Greenpeace report alleges that pulp and paper giant APP continues to clear forests and develop peatlands 10 years after adopting its landmark 2013 pledge to stop destroying natural forests for its plantations.
- The report identifies 75,000 hectares (185,300 acres) of deforestation in APP supplier concessions or companies connected to APP between February 2013 and 2022 — an area the size of New York City.
- APP has also changed the start date of its no-deforestation policy from 2013 to 2020, which would allow the company at some point in the future to accept new suppliers that deforested between 2013 and 2020.
- APP denies allegations of continued deforestation and says its suppliers have ceased forest conversions since 2013; the company also says it has committed to peatland restoration.
Myanmar’s primates and their guardians need more support, study says(Oct 30 2023)
缅甸是20种灵长类动物,making it the seventh most primate-rich country in Asia. However, a new study shows that all species are suffering population declines, with 90% of them threatened with extinction.
——冲突蹂躏的国家的研究人员和缺点ervationists are working in challenging conditions and are in dire need of more support from the international community, the study says.

- The study authors encourage conservation funders to not view Myanmar as a “no-go” zone due to the political situation, and propose recommendations to strengthen the field of primatology within the country.
Indigenous Dayak ‘furious’ as RSPO dismisses land rights violation complaint(Oct 27 2023)
- The RSPO, the world’s leading sustainable palm oil certifier, has dismissed a complaint filed by an Indigenous community in Indonesia against a plantation company accused of violating their land rights.
- The company, MAS, arrived on the Indigenous Dayak Hibun’s ancestral land in 1996, and by 2000 had swallowed up 1,400 hectares (3,460 acres) of the community’s land within its concession.
- The community lodged its complaint in 2012, aimed at MAS’s parent company at the time, Malaysian palm oil giant Sime Darby Plantation, which is a member of the RSPO.
- In dismissing the complaint, 11 years later, the RSPO cited no evidence of land rights violations, and also noted that Sime Darby Plantation has sold off MAS — whose current owner isn’t an RSPO member and therefore isn’t subject to the roundtable’s rules.

Forest conservation ‘off-track’ to halt deforestation by 2030: New report(Oct 24 2023)
- The world lost 6.6 million hectares (16.3 million acres) of forest, an area larger than Sri Lanka, and deforestation rates increased by 4% in 2022, according to a report published Oct. 24 that tracks commitments to forest conservation.
- The Forest Declaration Assessment is an annual evaluation of deforestation rates against a 2018-2020 deforestation and forest degradation baseline compiled by civil society and research organizations.
- Much of the forest loss occurred in the tropics, and nearly two-thirds of it was in relatively undisturbed primary forests, while forest degradation, more than deforestation, remains a serious problem in temperate and boreal forests.
- Despite being far off the pace to achieve an end to deforestation by 2030, a goal that 145 countries pledged to pursue in 2021, more than 50 countries have cut their deforestation rates and are on track to end deforestation within their borders by the end of the century.
