How Many Tree Species Exist on Earth?

How Many Tree Species Exist on Earth?

It may surprise you to learn that before today we didn’t know how many tree species there were in the world. A new paper ‘GlobalTreeSearch- the first complete global database of tree species and country distributions’, published today in the Journal of Sustainable Forestry, highlights the fact that more than half of all tree species only occur in a single country, and many of these species are threatened with extinction. Of all the countries in the world, Brazil has the most tree species, with 8,715 species, followed by Colombia (5,776) and then Indonesia (5,142). Apart from the Arctic and the Antarctic (which have no trees whatsoever), the region with the fewest tree species is the Nearctic region of North America, with fewer than 1,400 species.

The database comprises of over 375,500 records, which took over two years to compile. Dr Paul Smith, BGCI’s Secretary General, explains “Although it seems extraordinary that it has taken us until 2017 to publish the first global, authoritative list of tree species, it is worth remembering that GlobalTreeSearch represents a huge scientific effort encompassing the discovery, collection and describing of tens of thousands of plant species. This is ‘big science’ involving the work of thousands of botanists over a period of centuries.”

BGCI’s main reason for undertaking the challenge of documenting the world’s tree diversity was to provide a tool for people trying to conserve rare and threatened tree species. GlobalTreeSearch will form the backbone of the Global Tree Assessment, an initiative to assess the conservation status of all the world’s tree species by 2020. This will allow the prioritisation of the tree species that are most in need of conservation action so we can ensure that no tree species is lost forever.
