Zonoecotone II/III

  • Heinrich Walter

The zonoecotone II/III is transitional between the humid-arid climate of ZB II and the arid climate of the deserts of ZB III. The summer rain period becomes shorter and annual precipitation drops from about 400–500 mm to only 200–100 mm. When travelling through this region, one is immediately struck by the way in which the density of vegetation becomes ever less with the decrease in rainfall until, finally, in the desert itself the physiognomy is no longer determined by the plant cover, but by the naked soil or rock.
