Jonathan Barnard, RSPB Head of Tropical Forests
After miles and miles of fields cleared for agriculture and charcoal, suddenly insects are buzzing and you hear the swooshing of huge hornbills overhead. Pygmy hippos gaze from the rivers and rare monkeys jump through the canopy.
A century ago, the whole coast of west Africa was covered like this, with trees so big it took a dozen people to encircle them. Now 70% of it is gone.
Thanks to people like you, Gola Forest has been declared a national park by the Sierra Leonean government.
