Faced with finding a solution to human-wildlife conflict, researcher Lucy King, head of the human-elephant coexistence program at Kenya-based conservation group Save the Elephants, found bees were the answer. When elephants raid crops, it causes financial loss to the farmers and potential harm to the elephants. King learned that when elephants heard the distinctive sound of bees, they rounded up their herd and quickly moved away. So beehive fences were employed.
