BACKGROUND INFORMATION ON THE RAINFOREST

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 the second and third largest areas of tropical rainforest. Rainforests also exist on some the Caribbean islands, in Central America, in India, on scattered islands in the South Pacific, in Madagascar, 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.

ABOUT THE RAINFOREST (SUMMARY)

Chapter 1:

RAINFOREST DISTRIBUTION AND CHARACTERISTICS

Each rainforest is unique, but there are certain 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 estimated 229-247 billion tons of carbon) through photosynthesis; influencing precipitation patterns and weather; moderating flood and drought cycles; and facilitating 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:

1. Amazon: Includes parts of Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, Venezuela
2. Congo: Includes parts of Cameroon, Central African Republic, Democratic Republic of the Congo, Equatorial Guinea, Gabon, Republic of Congo
3. Australiasia: Includes parts of Australia, Indonesian half of New Guinea, Papua New Guinea
4. Sundaland: Includes parts of Brunei, Indonesia, Malaysia, Singapore
5. Indo-Burma: Includes parts of Bangladesh, Cambodia, China, India, Laos, Myanmar, Thailand, Vietnam
6. Mesoamerica: Includes parts of Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama
7. Wallacea: Sulawesi and the Maluku islands in Indonesia
8. West Africa: Includes parts of Benin, Cameroon, Côte d'Ivoire, Ghana, Guinea, Liberia, Nigeria, Sierra Leone, Togo
9. Atlantic forest: Includes parts of Argentina, Brazil, Paraguay
10. Choco: Includes parts of Colombia, Ecuador, Panama

Dozens of countries have tropical forests. The countries with the largest areas of tropical forest are:

• Brazil
• Democratic Republic of Congo (DRC)
• Indonesia
• Peru
• Colombia

Other countries that have large areas of rainforest include Bolivia, Cameroon, Central African Republic, Ecuador, Gabon, Guyana, India, Laos, Malaysia, Mexico, Myanmar, Papua New Guinea, Republic of Congo, Suriname, and Venezuela.

Chapter 2:

RAINFOREST STRUCTURE

Rainforests are characterized by a unique 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.

Chapter 3:

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.

There are several reasons why rainforests are so diverse. Some important factors are:

• Climate: because rainforests are located in tropical regions, they receive a lot of sunlight. The sunlight is converted to energy by plants through the process of photosynthesis. Since there is a lot of sunlight, there is a lot of energy in the rainforest. This energy is stored in plant vegetation, which is eaten by animals. The abundance of energy supports an abundance of plant and animal species.
• Canopy: the canopy structure of the rainforest provides an abundance of places for plants to grow and animals to live. The canopy offers sources of food, shelter, and hiding places, providing for interaction between different species. For example, there are plants in the canopy called bromeliads that store water in their leaves. Frogs and other animals use these pockets of water for hunting and laying their eggs.
• Competition: while there is lots of energy in the rainforest system, life is not easy for most species that inhabit the biome. In fact, the rainforest is an intensively competitive place, with species developing incredible strategies and innovations to survive, encouraging specialization.

While species everywhere are known for utilizing symbiotic relationships with other species to survive, the biological phenomenon is particularly abundant in rainforests.

Chapter 4:

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.

Chapter 5:

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.

Chapter 6:

Rainforest waters

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.

Chapter 7:

Rainforest people

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.

Chapter 8:

Deforestation

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:

• wood for both timber and making fires;
• agriculture for both small and large farms;
• land for poor farmers who don’t have anywhere else to live;
• grazing land for cattle (the single biggest driver of deforestation in the Amazon);
• plantations, including wood-pulp for making paper, oil palm for making palm oil, and rubber;
• road construction; and
• extraction of minerals and energy.

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.

Chapter 9:

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 that forests 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.

Chapter 10:

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.

The Latest News on Rainforests

In Kenya, a water fund brings to light Indigenous cultural identity issues (Nov 12 2024)
- Two years into its implementation, the Eldoret-Iten Water Fund (EIWF) in Kenya is helping to protect vital water resources, restore degraded forests and farmlands and work with local communities.
- While the EIWF has seen considerable success so far, several hurdles have emerged — including disputes with the Sengwer Indigenous community.
- The issues with the Sengwer community stem at least in part from decades of controversy over cultural identity and names, dating to colonial times.
- Despite these challenges, the EIWF, administered through The Nature Conservancy, has made progress and local farmers say they are hopeful about the future; for further details on the EIWF, see Part I of this story.

Bobcats are back, and they’re helping protect people from zoonotic disease (Nov 12 2024)
- In the last 125 years, bobcats have recovered significantly from extremely low numbers, with several million individuals found throughout North America today.
- Living at the interface of urban and rural environments, bobcats face many human-caused dangers, including loss of habitat to roam, automobiles, and rodent poisons.
- Bobcats help reduce the spread of diseases from animals to humans partly because they and other large mammals are poor disease vectors. Bobcats also prey on the small rodents that easily transmit pathogens.
- It’s legal to hunt bobcats in most of the United States. California, which has for five years closed the bobcat season, may reinstate hunting in 2025. Some researchers suggest that regulators should more carefully consider the role thriving wildcat populations play in protecting human communities from zoonotic diseases before expanding hunting.

A deadly fly is spreading through Central America. Experts blame illegal cattle ranching. (Nov 12 2024)
- An outbreak of screwworm — a fly that infects the open wounds of warm-blooded animals — is the direct result of cattle smuggling through protected areas across Central America, conservation groups said.
- The fly appeared in Panama last year and quickly traveled north to Guatemala. Now, officials are concerned it will spread uncontrollably into Mexico and the US.
- Eradicating the fly could cost millions of dollars and prove disastrous for agribusiness and countries that rely on beef exports.
- Conservation groups are arguing for border shutdowns and increased regulation of the cattle industry, especially around protected areas where smuggling routes have cleared forests.

Genetically modified cotton was planted in a Mato Grosso exclusion zone (Nov 12 2024)
- For five years, a farmer in Brazil disregarded biosafety measures and advanced into areas that prevented contamination of native cotton.
- In May 2024, Embrapa, which owns patents for genetically modified cotton, managed to eliminate the exclusion zones in Mato Grosso state.
- Indigenous people fear that the authorization to plant genetically modified cotton throughout the state will lead to contamination of their native varieties, which are used for handicraft production and medicinal purposes.

Peruvian fishers help red sea urchins recover from overfishing (Nov 12 2024)
- For 20 years, fishers from the district of Marcona, on Peru’s southern coast, have been recovering populations of red sea urchin, thanks to an alliance with the government.
- According to a monitoring study by the Peruvian Institute of the Sea, there are more urchins in the area where Marcona fishers work than in other areas.
- Part of the success is rooted in the spatial management of coastal areas that the artisanal fishers’ associations are applying; they are pioneers of this practice in the country.

At COP29, US envoy upbeat despite looming climate policy changes (Nov 11 2024)
Baku, Azerbaijan The outcome of the recent elections in the United States looms large on the United Nations Climate Change Summit, which opened in Baku, Azerbaijan, on Monday, Nov. 11, 2024. As thousands of delegates gathered at the Olympic Stadium in Baku, the venue of this year’s meeting, questions lingered regarding the role and leadership […]

A Kenya water fund partners with farmers to protect vital resources (Nov 11 2024)
- Kenya’s Eldoret-Iten Water Fund (EIWF) is one of dozens throughout the world, established to address threats to important water supplies.
- Administered through The Nature Conservancy, the EIWF’s objectives include partnering with thousands of local farmers to adopt sustainable soil and water conservation practices, restoring and protecting more than 120,000 hectares (300,000 acres) of degraded forests and farmlands, planting more than 1 million trees, reducing sediment flow into rivers and supporting farmers with rainwater harvesting.
- The EIWF also works with local Indigenous communities and includes projects such as beekeeping.
- The EIWF is a response to years of farming practices, population growth, deforestation for charcoal and wood and other factors that have diminished and threatened local water supplies.

Long-running tropical forest research stalls amid Venezuelan crisis (Nov 11 2024)
- Venezuela’s economic, institutional and economic collapse has put at risk a long-standing forest plot research network.
- With highly biodiverse forests covering about half of Venezuela’s total area, the country has some of the longest-running forest monitoring projects in the tropics, which represented a pioneering effort in understanding old-growth forest dynamics in the Amazon Basin.
- Falling budgets, a humanitarian crisis affecting personnel and logistics, the rise of armed gangs, and encroachment of logging and agriculture are some of the key factors threatening to halt research in the field.
- 2016 was the last year with still significant measurements in the field; today, projects lack permits to apply for international funding, but scientists continue to advocate for keeping efforts ongoing.

COP29: With public climate finance shortfall, is investment capital a way forward? (Nov 11 2024)
- The many years of international delay on climate action — paralleled by year-after-year of rising emissions and record climate disasters — has greatly increased the price tag on preventing a global climate catastrophe. Today, experts estimate addressing the climate emergency will cost trillions of dollars.
- But who should pay, and how much? This question is expected to top the agenda at COP29, the climate summit, starting Nov. 11 in Baku, Azerbaijan, possibly leading to a new, more ambitious financial target to provide crucial funds to developing countries.
- While wealthy nations are known for pledging large sums to support the alternative energy transition, climate adaptation, and loss and damage, those nations controversially are also known for falling far short on fulfilling those pledges. Wealthy countries reportedly mobilized $115.9 billion for climate action in 2022, still not close to enough.
- Now stepping up are The World Bank, International Monetary Fund, regional development banks, and private financial institutions, who say they stand ready to invest far more (with significant caveats) than G-20 nations ever contributed. How this investing will work, and how fast, remains to be seen, with some distrustful of investment capital’s profit motives.

What Indigenous leaders want from the COP29 U.N. climate conference (Nov 11 2024)
- As COP29 runs Nov. 11-22 in Baku, Azerbaijan, Indigenous leaders look ahead to show their strong participation, although many leaders are setting their sights on this conference to prepare better for the next COP.
- With a package of new funds introduced this year, Indigenous leaders whom Mongabay spoke with plan to push negotiations for improved access to direct funds to fight the harsh impacts of climate change.
- Along with improved access to funds, the leaders say they seek ambitious commitments to the loss and damage fund, a just energy transition and carbon market regulations.

Gibbons found to perform dance routines akin to ‘the robot,’ but why? (Nov 11 2024)
- Scientists have documented scores of animal species that perform elaborate dance displays for a variety of purposes: from courting cranes to pair-bonding penguins and waggle-dancing honeybees.
- New research and video evidence show that adult female crested gibbons also perform captivating dances in both captive and wild settings.
- The funky sequences of rump, arm and leg twitches have in the past been likened to the human “robot dance” and hypothesized as fulfilling a role in gibbon courtship.
- Experts say improved understanding of the dance brings new insight into small ape cognition and social structures, which will ultimately help conservationists better design and implement interventions to protect them.

Killing of jaguar pushes species’ survival in Argentina’s Gran Chaco to the brink (Nov 11 2024)
- The recent killing of a jaguar by hunters increases the species’ risk of extinction in Argentina’s Gran Chaco landscape, where no more than 10 of the big cats are thought remain.
- Images of this particular jaguar were captured by camera trap twice this year as it traveled through a biological corridor; the next time it was photographed was on social media, where hunters posed with its carcass and its pelt.
- A tradition of hunting, lack of public awareness, persistent deforestation, and absence of female jaguars — there’s only one, recently rewilded into the area — are the biggest obstacles to the jaguar’s survival in the Argentine Gran Chaco.

Amazon deforestation in Brazil plunges 31% to lowest level in 9 years (Nov 10 2024)
- Deforestation in the Brazilian Amazon dropped by 30.6% over the past year, reaching its lowest level since 2015, with 6,288 square kilometers cleared by July 31, 2024.
- Despite the drop in deforestation, fires surged nearly 18-fold in September due to severe drought, with fire hotspots up 70% from the previous year.
- Fires impacted ecosystems across South America, especially in Brazil’s Pantanal and Cerrado. But deforestation also dropped in the Cerrado, falling 25.7%.
- The Amazon faces increasing threats from climate change, deforestation, and degradation, raising concerns about destabilizing rainfall patterns and biodiversity loss.

The rubber boom and its legacy in Brazil, Peru, Bolivia and Colombia (Nov 8 2024)
- In the Amazon, the rubber boom was facilitated by new technological developments, industrialization and political change.
- While in Brazil the rubber barons used a form of debt slavery with their workers, in Bolivia the rubber boom was dominated by pioneers from Santa Cruz who had established cattle ranches in the Beni during the nineteenth century.
- In Peru, the boom was based on the exploitation of Castilla species rather than Hevea, resulting into a much more destructive process, which developed a particularly cruel and exploitive slave-labor system.

U.S. policy experts confident of future climate action despite Trump election (Nov 8 2024)
- In 2015, the world came together to achieve the landmark Paris climate agreement. But in 2016, Donald Trump’s ascendency to the U.S. presidency stunned the world, as he promised to withdrew the U.S. from the Paris accord and moved to disrupt action on climate change.
- The Biden administration worked to reverse that damage, with the U.S. again taking a leadership role in global climate summits and passing the Inflation Reduction Act, one of the most ambitious U.S. laws ever to combat global warming and boost the post-carbon economy.
- Now, with Trump elected again, the world stands ready for his climate denialism, and his likely withdrawal of the U.S. for a second time from the Paris Agreement. Global momentum is expected to continue unabated, with alternative energy thriving, Brazil hosting COP30 in 2025, and China and the EU doubling down on climate action.
- In the U.S., “Just as we did during the last Trump administration, we are going to put a focus on our work with cities and with states and many private-sector leaders who stood tall then and stand tall now,” said Gina McCarthy, EPA administrator during Barack Obama’s second term, and managing co-chair of America Is All In, an NGO.
