Climate policies alone will not save Earth's most diverse tropical forests

Afocus on policies to conserve tropical forests for their carbon storage value may imperil some of the world’s most biologically rich tropical forests.

Many countries have climate-protection policies designed to conserve tropical forests to keep their carbon locked up in trees. But a new study suggests these policies could miss some of the most diverse forests because there is no clear connection between the number of tree species in a forest and how much carbon that forest stores.

Lead author Dr Martin Sullivan, from the School of Geography at the University of Leeds, said: “International programmes often encourage the conservation of forests with high carbon stocks, because their focus is to try to slow climate change. Until now, we didn’t know whether these programmes would also automatically protect the most biodiverse forests. It turns out they probably won’t.”

A team of scientists from 22 countries measured both tree diversity and the amount of carbon stored in 360 locations across the lowland rainforests of the Amazon, Africa and Asia. In each plot the carbon stored was calculated using the diameter and identity of every tree within a given hectare (2.5 acres). In total 200,000 trees were measured in the study.
