Over half of the tropical forests is under hunting pressure. According to scientists at Radboud University, hunting causes an abundance decline of on average 27 and 40% of medium and large-size mammals in the tropics of central and south America, Africa and Asia. Even forests that are considered intact according to satellite images, could be partially defaunated. These results are published in PLOS Biology.
