Trees... Natures Billion Dollar Secret

A World of Trees

The global extent and distribution of forest trees is central to our understanding of the terrestrial biosphere. We provide the first spatially continuous map of forest tree density at a global scale. This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate. Of these trees, approximately 1.30 trillion exist in tropical and subtropical forests, with 0.74 trillion in boreal regions and 0.66 trillion in temperate regions. Biome-level trends in tree density demonstrate the importance of climate and topography in controlling local tree densities at finer scales, as well as the overwhelming effect of humans across most of the world. Based on our projected tree densities, we estimate that over 15 billion trees are cut down each year, and the global number of trees has fallen by approximately 46% since the start of human civilization.

World of Trees - Number of Trees

New satellite technology has now shown that Earth is home to more than

3 trillion trees…

roughly seven and a half times higher than previous estimates.

To put it another way, for every human, there are about 422 trees.

World of Trees - Number of Species

There are 60,065 species of trees in the world, according to a comprehensive study of the world's plants.

Botanical Gardens Conservation International (BGCI) compiled the tree list by using data gathered from its network of 500 member organizations.

World of Trees - Satellite Map of Trees

Global Forest Watch (GFW) is an online platform that provides data and tools for monitoring forests.

By harnessing cutting-edge satellite technology, GFW allows anyone to access near real-time information about where and how forests are changing around the world.
