Amazon rainforest has 11,676 tree species

So many different tree species grow in the Amazon rainforest that it will take another 300 years to discover them all, say scientists.

Researchers made the prediction after conducting an audit of more than half a million museum specimens collected from the Amazon between 1707 and 2015.

They ended up with a list of 11,676 different tree species. Based on this figure, they believe about 4,000 of the rarest Amazonian trees remain to be discovered and described.
