The Islands Within The Okavango Delta Were Created By Termites | Termite Control
The world is full of remarkable land formations that capture the fascination of many people, particularly scientists. Some land formations are mysterious in that researchers have yet to understand how they were formed. Land formations that are commonly found to be awe inspiring stand a good chance of making it onto the list of UNESCO World Heritage sites. Unbelievably, termites are credited with contributing to two different types of land formations. These land formations include the famous fairy circles in Africa and the islands located in the Okavango Delta in northern Botswana. The fact that termite activity is largely responsible for these land formations has only recently been understood by scientists. The islands in the Okavango Delta in northern Botswana were not only made by termites, but the Okavango Delta was recently added to the list of UNESCO World Heritage sites.
In order to have a land formation be considered as an UNESCO World Heritage site the area must be deemed to have “outstanding universal value”, and the islands located within the Okavango Delta certainly qualify. The land formations are unique because they are essentially small islands located in a wetland in the middle of the desert. This particular delta is also strange in that it does not flow into the ocean. The islands could only have been formed by multiple ecological factors that rarely work together to create land formations.
When it comes to the formation of the delta’s islands, termites are the factor that scientists had never considered until fairly recently. The islands began as termite mounds that eventually grew trees and formed into islands. As the trees grew, more water and nutrients were brought up to the surface in order to nurture the tree’s growth. After awhile this process drained the delta of water, but the water was replaced by water from nearby floodplains. Researchers believe that most islands within Botswana’s deltas originated as termite mounds.
Have you ever visited a delta containing islands that were most likely formed by early termite mound building activity?
