Rainforests of the World (Infographic)

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 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 a 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.

This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 5,500,000 km2 (2,100,000 sq mi) are covered by the rainforest. The Amazon represents over half of the planet’s remaining rainforests, and comprises the largest and most biodiverse tract of tropical rainforest in the world, with an estimated 390 billion individual trees divided into 16,000 species. Image: Wikipedia

Todd Smith, an advocate of rainforest preservation with an interest in ecology, has created a very informative infographic the world’s most prominent rainforests. You can see this incredible work below:

Amazon Rainforest

The Amazon rainforest is the biggest rainforest in the world. It covers most of the Amazon basin of South America. This basin encompasses 7,000,000 km2 (2,700,000 sq mi), of which 5,500,000 km2 (2,100,000 sq mi) are covered by the rainforest. This region includes territory belonging to nine nations. The majority of the forest is contained within Brazil, with 60% of the rainforest, followed by Peru with 13%, Colombia with 10%, and with minor amounts in Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana.


Congo Rainforest

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. Endangered wildlife, including forest elephants, chimpanzees, bonobos, and lowland and mountain gorillas inhabit the lush forests. 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 unequaled by that of the Amazon or African rainforests. Unfortunately, they are shrinking much faster than any other rainforests 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 extending 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, 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 Notes 1 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, the 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 process, 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 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 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 the temperate rainforests.
  3. The World Wide Fund for Nature (WWF) is an international non-governmental organization founded in 1961, working in the field of the wilderness preservation, and the reduction of human impact on the environment.

About the Author

Todd Smith is the owner of Jarrimber, stockists of quality Jarrah furniture in Australia. He explains “We use Jarrah and Marri timbers in the manufacture of our products, many of which are constructed from recycled timber. Our company is dedicated to promoting environmental responsibility and, where possible, we will always use recycled timber in our factory rather than new timber. Even though our business sells timber products, I would be an advocate of rainforest preservation and I’ve always had an interest in ecology, which is why I wanted to put this infographic together.” For more information visit jarrimber.com.au
