Ecologists in Gonarezhou National Park, in the south-east of Zimbabwe, have come up with a simple but ingenious method for keeping elephants from damaging baobab trees. There aren’t many places left in the world suffering from too many elephants, but this extraordinary and beautiful park is one that is. And the poor baobab trees are feeling the pressure! Join Gus, the African Plant Hunter, as he wanders through the park and encounters a baobab that has been protected using this method. It’s simple, but it works!
