The facts behind Fairy circle.

Fairy circles are circular patches of barren land, varying between 2 and 12 metres in diameter, often encircled by a stimulated growth of grass.

Fairy circles are circular patches of barren land, varying between 2 and 12 metres in diameter, often encircled by a stimulated growth of grass. They occur in the arid grasslands of the Namib desert in western parts of Southern Africa and in a part of the Pilbara in Western Australia. Studies have proposed various hypotheses about their origins, but none have conclusively proven how they are formed. Theories include hypotheses that the activities of various types of termites affect growth or that competition between grasses naturally yields certain vegetation patterns.
