Filmmaker Martin Harvey documents the wildlife in Botswana, capturing the beauty of Okavango Delta and the Makgadikgadi Pans. The Okavango Delta is a delta in Northwest Botswana teeming with endangered species of large mammals, including cheetahs, white rhinoceros, black rhinoceros, African wild dogs and lions. UNESCO World Heritage protects two million hectares of this pristine delta. Okavango is an important site of support for elephants, as Botswana has the largest elephant population in the world. The delta is also species-rich in terms of plant life, possessing over 1,000 plant species. The Makgadikgadi Pans lie south-east of the Okavango Delta. From February to March, zebras, oryx, wildebeests, impalas and springbok graze Makgadikgadi National Park. The national park has never been inhabited by humans and is rather remote.
