Site description (1994 baseline)
A vast area of cultivated upland plains and gently undulating hills, c.90 km from east to west and 30 km north to south, including the broad valleys of the Rud-i Jowin and Rud-i Kalshur rivers. The rivers flood in winter and spring and are reduced to a series of stagnant brackish pools by late summer. There are some seasonally flooded brackish marshes. Other habitats include cultivated land (mainly cereals), salt-tolerant vegetation in depressions on the valley floors, and Artemisia steppe on the rolling hills. There is some livestock grazing.
