"The world's remaining ancient forests are vital to the future of the planet. Forests are home to two thirds of all known species of land plants and animals. They are also home to thousands of indigenous cultures that rely on forests for food, water and the necessities of life. Forests also play a key role in regulating local and global climate. They are vital to the future of life on Earth.
This Greenpeace map is the first global assessment of remaining tracts of intact forest landscapes larger than 500 sq. km that are not fragmented by infrastructure, such as roads, settlements, waterways, pipelines, power lines etc. These tracts are located within the forest vegetation zone and are mostly forested but also contain swamps and other non-forested ecosystems which are without significant visible signs of human impact such as logging, burning or other forms of forest clearing."
