Beauty of Nature

Five top forest in the  World

1. 

Amazon Rainforest 

Size: 5,5 million sq km / 2,1 million sq mi

The territory of the Amazon Rainforest stretches across nine countries, representing over half of the world’s remaining rainforests. About 70 per cent of the total forest area is in Brazil and Peru. Heavy logging in the past decades reduced the original forest area of about 7 million sq km to 5,5 million sq km

The Amazon Rainforest hosts a wealth of biodiversity and valuable freshwater resources. It does not only play a crucial role for global biodiversity conservation, but also provides essential ecological services as a carbon sink.

2

Canada 

Size: 4,2 million sq km / 1,6 million sq mi

Forests in Canada occupy 4,2 million sq km and cover almost half of the country’s territory. A great variety of forest types stretch from the Pacific to the Atlantic coast and up to the Arctic tree line in the north. The northern boreal forests, the largest contiguous intact forests left on Earth, cover more than one third of the Canada’s land mass.

Commercial logging, mining, and hydroelectric generation pose big threats to Canada’s forests. About 4,000 sq km are logged every year. Canada is also the world’s most important exporter of paper products, responsible for more than a quarter of the world’s paper exports.

3.EAST-Siberian Taiga

East-Siberian Taiga 

Size: 3,9 million sq km / 1,5 million sq mi

The coniferous forests in East-Siberia, called “Taiga” in Russian, stretch across 3,9 million sq km between Tundra in the north and temperate mixed forests in the South. Flora and Fauna have to withstand enormous temperature variations between 100° F (40° C) in the summer and -80° F ( -62° C) in the winter.

With more than 8 million sq km (3,1 mio. sq mi) covered by forests, an area that is almost twice as big as the European Union, Russia has more forest area than any other country and over one fifth of the world’s forest reserves.

4.

USA 

Size: 3 million sq km / 1,2 million sq mi

3 million sq km of forest cover the United States. The large tracts of forest in the U.S. provide habitat for far-ranging species like elk, buffalo, and wolves. Among the U.S.’s most important forests are the Sierra Nevada conifer forests. They are home to a great variety of conifers including the Giant Sequoia, the world's largest tree.

Currently, forest cover in the U.S. is stable. However, within the last two centuries, about 20 per cent of North American forests have been cleared and as human populations grow, forest fragmentation and degradation continues.

5.

Scandinavian and Russian Taiga 

Size: 2,16 million sq km / 834,000 sq mi

The Scandinavian and Russian Taiga, the largest ecoregion in Europe, occupies about 2,1 million sq km in Finland, Norway, Sweden, and parts of Western Russia and covers almost one third of Europe.

It is of global ecological significance because it locks billions of tons of carbon dioxide and provides excellent nesting habitat for many birds. Fossil fuel exploration, logging, mining, and increasing tourism are heavily threatening this ecoregion. Finland and Scandinavia also tail Canada as the world’s most important exporters of paper-products.
