Half of All Trees in Amazon Belong to 227 Tree Species, Researchers Estimate

Greater Amazonia has 227 dominant tree species

There are about 390 billion individual trees in greater Amazonia, according to estimates based on over 10 years of data. The region has 16,000 tree species but, over half of all trees belong to 227 “hyperdominant” tree species.

Despite being home to the world’s largest carbon sink, vast regions of the Amazon have largely remained unexplored. The latest study was conducted by over 100 experts who contributed data from over from 1,100 forestry surveys. Greater Amazonia includes Amazon Basin and the Guiana Shield.

“We think there are roughly 16,000 tree species in Amazonia, but the data also suggest that half of all the trees in the region belong to just 227 of those species! Thus, the most common species of trees in the Amazon now not only have a number, they also have a name. This is very valuable information for further research and policymaking,” said Hans ter Steege, first author on the study and researcher at the Naturalis Biodiversity Center in South Holland, Netherlands.
