the 6-million-square-kilometre basin. Hans ter Steege of the Naturalis Biodiversity Center in Leiden, the Netherlands, and his colleagues analysed data from 1,170 plots scattered across the

forest and then extrapolated their data to the entire basin. They calculated that the region contains around 390 billion trees with trunks of 10 centimetres or more in diameter, and some

16,000 species. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to this journal Receive 51 print issues and
