Recent data from the International Union for the Conservation of Botanical Gardens show that there are more than 60,000 species of trees worldwide. What is their conservation status, but no one can answer exactly.

A study published online June 17 in the Proceedings of the National Academy of Sciences of the United States of America by an international team of East China Normal University and Aarhus University in Denmark shows that on average, about 50 percent of the habitat of each tree species worldwide is distributed outside existing protected areas, and that 6,377 vulnerable tree species are not in any protected area.

The study suggests that global tree species diversity is under serious threat from human activities.
