What are the causes of mysterious barren “fairy circles”? Mike Cramer, Nichole Barger and Walter Tschinkel in a recent paper suggest that they are produced by interactions between grasses enabled by coarse textured sand. Water and nutrients are highly mobile in the sands, allowing fairy circles to interact over distances > 5 m. The authors concluded that fairy circles are more closely associated with a highly connected soil environment, rather than particular biota.
