10 Largest Forests in the World
10. Australian Tropical Rainforests
- Location: Found primarily in Queensland and Northern Australia, extending into Papua New Guinea.
- Area: Around 50,000 km² (19,300 square miles).
- Key Features: The Australian tropical rainforests are known for their rich biodiversity, with ancient species of plants and animals, some of which are found nowhere else on Earth. Famous rainforests like the Daintree are part of the Wet Tropics of Queensland World Heritage Area. These rainforests are crucial for maintaining the region’s water cycle and stabilizing local climates. However, they face threats from logging and land conversion for agriculture.
9. Borneo Rainforest
- Location: Borneo (Indonesia, Malaysia, and Brunei).
- Area: Approximately 748,000 km² (288,000 square miles).
- Key Features: Borneo’s rainforests are some of the oldest in the world, hosting unique species like orangutans, pygmy elephants, and the proboscis monkey. The rainforest is also home to the world’s largest flower, Rafflesia arnoldii. The forest plays a vital role in carbon storage but is endangered due to illegal logging, palm oil plantations, and deforestation.
8. New Guinea Rainforest
- Location: Located on the island of New Guinea, which is split between Papua New Guinea (to the east) and Indonesia (to the west).
- Area: Around 7.5 million km² (2.9 million square miles).
- Key Features: One of the oldest and most biodiverse rainforests on Earth, the New Guinea rainforest is home to unique species like the tree kangaroo and the world’s largest butterfly, the Queen Alexandra’s birdwing. Despite its rich biodiversity, it faces growing pressures from logging and mining activities, which threaten its fragile ecosystems.
7. Valdivian Temperate Rainforest
- Location: Southern Chile and Argentina (Patagonia).
- Area: Approximately 248,000 km² (95,000 square miles).
- Key Features: This temperate rainforest is known for its ancient, towering trees, including the Alerce tree, which can live for thousands of years. It is one of the most biodiverse temperate ecosystems, with species like the pudú (the world’s smallest deer) and the endangered Chilean native forest. It has been designated a UNESCO World Heritage Site due to its ecological importance.
6. Pacific Northwest Rainforest
- Location: United States (Washington, Oregon) and Canada (British Columbia).
- Area: Around 150,000 km² (58,000 square miles).
- Key Features: Famous for its towering coastal redwoods and Douglas firs, the Pacific Northwest rainforest is one of the largest temperate rainforests in the world. It is home to diverse wildlife, including the endangered spotted owl and salmon. The forest plays an essential role in the carbon cycle and is critical for maintaining regional biodiversity and water systems.
5. Boreal Forest of Russia
- Location: Russia (Siberia and beyond).
- Area: Around 6.5 million km² (2.5 million square miles).
- Key Features: The boreal forests of Russia are the largest contiguous forest region in the world. They are dominated by coniferous trees such as spruce, pine, and larch, and provide vital ecosystem services, including carbon sequestration and habitat for species like Siberian tigers and brown bears. These forests are highly sensitive to climate change and human-induced disturbances such as logging and mining.
4. Southeast Asian Rainforest
- Location: Southeast Asia (Indonesia, Malaysia, Papua New Guinea, Thailand, Philippines).
- Area: Approximately 2.5 million km² (965,000 square miles).
- Key Features: Known for its extraordinary biodiversity, Southeast Asia’s rainforests are home to iconic species like orangutans, tigers, and rhinoceros. These forests are vital for maintaining regional rainfall patterns and controlling the climate. However, they are under severe threat from deforestation driven by agriculture, logging, and palm oil plantations.
3. Taiga (Boreal Forest)
- Location: Northern parts of North America, Europe, and Asia (Canada, Russia, Scandinavia).
- Area: Around 12 million km² (4.6 million square miles).
- Key Features: The taiga, or boreal forest, is the world’s largest terrestrial biome, made up mostly of coniferous trees like pine, spruce, and fir. These forests act as a significant carbon sink and regulate the Earth’s climate. The taiga is home to large mammals like moose, wolves, and bears and serves as an important ecosystem for migratory birds.
2. Congo Basin Forest
- Location: Central Africa (Cameroon, Central African Republic, Congo, Gabon, Equatorial Guinea, Democratic Republic of the Congo).
- Area: Approximately 3.7 million km² (1.4 million square miles).
- Key Features: The Congo Basin rainforest is the second-largest tropical rainforest in the world. It is crucial for regulating global climate patterns, absorbing large amounts of CO2, and hosting rich biodiversity, including gorillas, elephants, and the okapi. The forest also provides essential resources for local communities, though it is increasingly under threat from logging and mining.
1. Amazon Rainforest
- Location: South America (Brazil, Peru, Colombia, Venezuela, Ecuador, Bolivia, Guyana, Suriname, French Guiana).
- Area: Approximately 5.5 million km² (2.1 million square miles).
- Key Features: The Amazon is the largest tropical rainforest in the world and one of the most biodiverse ecosystems on Earth. It plays a critical role in regulating the global climate by absorbing vast amounts of CO2 and producing oxygen. Home to species such as jaguars, sloths, and countless plant species, the Amazon is often referred to as the “lungs of the Earth.” It is under significant threat from deforestation, particularly due to agriculture and illegal logging.

FAQs
Why are forests important?
Forests are essential for life on Earth. They produce oxygen, absorb carbon dioxide, and regulate the climate. Forests provide critical habitats for wildlife, help in water filtration, prevent soil erosion, and offer resources such as wood, food, and medicinal plants. They are also vital for maintaining biodiversity and play a key role in combating climate change by acting as carbon sinks.
What is deforestation and why is it a problem?
Deforestation refers to the large-scale removal or clearing of forests, often for agriculture, logging, or urban development. This is problematic because it leads to loss of biodiversity, disrupts ecosystems, and accelerates climate change by releasing stored carbon dioxide into the atmosphere. Deforestation also disrupts water cycles, affects soil fertility, and diminishes natural resources.
What is reforestation?
Reforestation is the process of planting trees in an area where a forest has been cut down or destroyed. It is an important practice to restore ecosystems, improve biodiversity, prevent soil erosion, and combat climate change by absorbing carbon dioxide. Reforestation helps rebuild natural habitats and can be an effective tool for reversing some of the damage caused by deforestation.
How much of the Earth’s surface is covered by forests?
Forests cover approximately 31% of the Earth’s total land area, which is about 4 billion hectares. These forests are spread across different climates, from tropical rainforests near the equator to temperate and boreal forests in cooler regions. However, this percentage has been steadily decreasing due to deforestation, particularly in tropical regions.
What are the main threats to forests?
The primary threats to forests include:
Deforestation: Driven by agricultural expansion, logging, mining, and urbanization.
Climate Change: Increasing temperatures, droughts, and forest fires are making forests more vulnerable.
Illegal Logging: Unregulated tree-cutting for timber and fuel wood.
Pollution: Air, water, and soil pollution can degrade forest ecosystems.
Invasive Species: Non-native plants, animals, and diseases can disrupt native forest ecosystems.
