The Okavango Delta in Botswana is one of the world’s largest inland deltas. While most river deltas usually lead to a sea or ocean, the Okavango River empties onto open land, flooding the savanna and creating a unique and ever-changing inland delta. One of the unique characteristics of the site is that the annual flooding from the River Okavango occurs during the dry season, with the result that the native plants and animals have synchronized their biological cycles with these seasonal rains and floods. The Okavango Delta is deemed one of the world’s premier wilderness areas. It is home to elephants, buffaloes, giraffes, hippos, zebras and many other species of large mammals, including also some of the world’s most endangered species, such as black rhinoceros.
