With their water-rich interiors, baobabs are part of the park’s attraction to elephants. The natural process of elephants digging into these trees doesn’t usually cause lasting damage. Baobabs have a unique ability among trees to recover their bark and tissue, says David Baum from the University of Wisconsin-Madison, who has studied the trees for more than 30 years. “Baobabs have coexisted with elephants for millions of years, which probably explains why they have evolved such a remarkable ability for regrowth,” he says.
