Despite having protected status, the biodiversity in a large number of tropical forests is still continuing to decline, a study has suggested.
The authors said the findings should cause concern because the areas have been seen as a final refuge for a number of threatened species.
Habitat disruption, hunting and timber exploitation have been seen as signs of future decline, they added.
The findings have been published online by the science journal Nature.
“The rapid disruption of tropical forests probably imperils global biodiversity more than any other contemporary phenomenon,” the international team of research wrote.
