Okavango elephants

Article Abstract:

Botswana's Okavango Delta is home to nearly 70,000 elephants, whose numbers have been growing steadily, causing concerns about their voluminous consumption of native vegetation. A researcher has discovered fires set by hunters cause greater damage than elephants in some parts of the savannah, so reducing herds by a set formula may not actually improve the ecology. A harrowing adventure in surviving an elephant stampede is also described.
