Scientists name the commonest tropical tree species for the first time

decorative A major international collaboration of 356 scientists led by UCL researchers has found almost identical patterns of tree diversity across the world's tropical forests. The study of over one million trees across 1,568 locations, published in Nature , found that just 2.2% of tree species make up 50% of the total number of trees in tropical forests across Africa, the Amazon, and Southeast Asia. Each continent consists of the same proportion of a few common species and many rare species. While tropical forests are famous for their diversity, this is the first time that scientists have studied the commonest trees in the world's tropical forests. The scientists estimate that just 1,053 species account for half of the planet's 800 billion tropical forest trees. The other half are comprised of 46,000 tree species. The number of rare species is extreme, with the rarest 39,500 species accounting for just 10% of trees.
