Number of Earth’s tree species estimated to be 14% higher than currently known, with some 9,200 species yet to be discovered

A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered. Researchers from Institute of Botany of the Czech Academy of Sciences have been involved in the research by supplying unique data from research plots in East Asia in the Russian Far East, Korea, Japan, Europe and West Africa. These are all sites where researchers are conducting long-term monitoring of forest stands.
