This study involves in the investigation of halophytic vegetation in Igdir Plain which comprises of partly summer drying and partly prominent saline and alkaline marshes, located near Ararat Mountain in the Eastern Turkey. Six associations and three sub-associations were identified in the plain. Arthrocnemetum glaucum, Halimiono-Arthrocnemetum glaucum and Halocnemo-Salsoletum macrae associations were described in the area where the soil surface was covered by a white salt crust accompanying with extremely sodium, boron and lime contents. Junco-Puccinellietum distans association was widespread in the waterlogged marshes area of the plain while Panderino-Tamericetum parviflorae association prevailed on the soils containing small amount of salt and lime, and having no alkalinity and acidity problem (i.e. neutral in pH). Kochio-Schismetum arabicus was seen in the soil showing the characteristics of no salinity and low alkalinity problem and containing small amount of lime. This area was the transition zone between the wind erosion and highly saline and alkaline soils. All these associations, except Arthrocnemetum glaucum, were described in this study for the first time. Junco-Puccinelliatum distans association was included in Puccinellio-Salicornion europae alliance of Salsola-Aeluropetalia litoralli order. The other associations were grouped under Alhagio-Suaedion microphyllae alliance that was identified in this study for the first time.
