World is home to ‘60,000 tree species’

The data revealed that Brazil was the nation with the greatest number of tree species, home to 8,715 varieties. Apart from the polar regions, which have no trees, the near-Arctic region of North America had the fewest number of species, with less than 1,400.

Another fact to emerge from the data was that more than half of the species (58%) were only found in one country, suggesting that they were vulnerable to potential threats, such as deforestation from extreme weather events or human activity.

About 300 species have been identified as critically endangered as they had fewer than 50 individuals remaining in the wild.
