The work lasted years and involved researchers and institutions around the world. And the end result is that in the world there are currently 60 065 different species of trees. The number is expected to grow because studies also say that every year they are identified around 2,000 new ones.
The research is of great importance for the definition of the tree heritage varieties of the planet and for its enhancement and conservation, not only by those who work in the green.
The "list" of species was compiled by Botanic Gardens Conservation International, which classified different species also with the aim of identifying the most rare and endangered. The research (entitled Global Tree Search) also gave Brazil the top spot as the country that has the largest number of tree species.
