Site description A 55-km stretch of the Karkheh river and adjacent marshy plains (3,500 ha of wetlands), c.35-90 km north-north-west of Ahwaz. The river flows in a deep channel with steep earth banks. Dense riverine forest of Tamarix and Populus euphraticus, up to several hundred metres wide, lines the river banks. The adjacent plains, largely cultivated with wheat, are dotted with shallow marshy depressions and meandering creeks which flood in winter.

Other biodiversity Mammals: a tiny population of Dama mesopotamica (E) still survived along the Karkheh river until the early 1970s, but apparently became extinct in the mid- or late 1970s, leaving the population along the Dez river to the east as the only one known in the wild. Other species include Gazella subgutturosa (rare).
