Hi, Lisa, I guess you're referring to the work of our friend and colleague, Lucy King of Save The Elephants (see the press release at http://www.savetheelephants.org/diary-reader/items/save-the-elephants-pr...), about the flight response of eles to bees, including a rumble that seems to mean "Watch out, there are bees about!". In fact, we have known about bees as elephant deterrents for some while. We helped STE with a project to put traditional Samburu beehives in Acacia tortilis trees to keep the elephants from bashing the trees. And Winnie Kiiru, one of our doctoral students, was helping farmers in the Oloitokitok area of Amboseli add bees to their arsenal of elephant repellants. Never thought of bees as a park management tool. Good idea. Maybe you should write to the Kenya Wildlife Service and suggest it. Thanks for the idea and your interest.
