The “Death Zone” – Decoding the Secrets of the Namib Desert’s Fairy Circles

With substantial fieldwork, researchers from the University of Göttingen in Germany and Ben Gurion University in Israel examined how freshly germinated yard passes away inside the fairy circle.Their results program that the grass withers due to an absence of water inside the fairy circle. Under these conditions, freshly germinated yards can not survive in the fairy circle: they dry out due to the fact that they can not reach the much deeper, more wet layers of soil with their roots, which are on typical 10 centimeters long.Implications for Grass GrowthIn contrast, the large, perennial clumps of yard that grow at the edge of the fairy circle benefit from being able to access the soil water to a depth of 20 to 30 centimeters and listed below. As a result, the clumps of grass mainly draw water from the leading 10 to 20 centimeters of the soil.Getzin says: “This is the cause of the death of the brand-new turf in the fairy circle.

A common fairy circle on the Kamberg, which the researchers examined throughout the 2024 rainy season: The clumps of turf– up to 80 cm high– can be seen at the edge of the fairy circle. With substantial fieldwork, researchers from the University of Göttingen in Germany and Ben Gurion University in Israel examined how freshly germinated yard dies inside the fairy circle.Their results show that the turf withers due to an absence of water inside the fairy circle. Under these conditions, newly sprouted lawns can not survive in the fairy circle: they dry out due to the fact that they can not reach the much deeper, more wet layers of soil with their roots, which are on typical 10 centimeters long.Implications for Grass GrowthIn contrast, the big, perennial clumps of yard that grow at the edge of the fairy circle benefit from being able to access the soil water to a depth of 20 to 30 centimeters and listed below. As an outcome, the clumps of grass primarily draw water from the top 10 to 20 centimeters of the soil.Getzin says: “This is the cause of the death of the brand-new grass in the fairy circle. It is a methodical adaptation to an absence of resources in dry areas,” say Getzin and his associate Dr Hezi Yizhaq.In their yizhag, getzin and study likewise comment on the theory that termites reduce the roots of fresh yard in the fairy circle by feeding on them, causing the new lawn to die.
