Quote:Small fairy circles stick around an average of 24 years, while larger ones can exist as long as 75 years, according to research detailed today (June 27) in the journal PLoS ONE. Still, the study sheds little light on why the circles form, persist and then vanish into the landscape after decades.
Few researchers have studied fairy circles, in part because of their remoteness, 111 miles (180 km) from the nearest village.
By comparing satellite images from 2004 and 2008, he found that circles are quite stable, popping up at nearly their full size, or growing quickly to full size once they get started. The smallest are about 6.5 feet (2 meters) in diameter, while the largest can be almost 40 feet (12 m) across. Winds scour the bare areas of soil, turning them into slight depressions. Eventually plants move back in, recolonizing the circles and leaving only slightly indented "ghost circles" behind.
Nature is so ƒükking cool!
I am not your rolling wheels, I am the highway
I am not your carpet ride I am the sky
I am not your blowing wind, I am the lightning
I am not your autumn moon, I am the night
