What is the Okavango Delta?
The Okavango Delta is a vast inland river delta in northern Botswana. It's known for its sprawling grassy plains, which flood seasonally, becoming a lush animal habitat. The Okavango Delta is one of the Seven Natural Wonders of Africa and was declared the 1000th UNESCO World Heritage Site in 2014.
Key Facts about the Okavango Delta
- The delta covers an area of 15,000 square kilometers (5,800 sq mi) during the dry season, expanding to over 22,000 square kilometers (8,500 sq mi) during the wet season.
- It is formed where the Okavango River empties onto a swamp in an endorheic basin in the Kalahari Desert, where most of the water is lost to evaporation and transpiration instead of draining into the sea.
- The Okavango is home to a rich diversity of wildlife, including elephants, hippos, crocodiles, lions, leopards, cheetahs, rhinoceroses, zebras, and over 400 species of birds.
- The delta's floods are seasonal, with the highest water levels typically occurring between June and August, during Botswana's dry winter months.
