Vegetation of dust sources in Khuzestan Province

The area of dust sources in Khuzestan Plain is 349254 hectares, including seven distinct regions: south west of Hovizeh, north east of Khoramshahr, east of Ahvaz, south and south east of Ahvaz, Bandare Emam to Omidieh, Mahshahr to Hendijan, and east of Hendijan. This research was aimed to introduce the native species of the study area to be planted under saline and water deficit conditions. Based on observations, the species richness of the study area is poor due to the characteristics of the Khuzestan plain, covered with fine sediments. However, changes in soil properties and human activities is the main factor of vegetation variety in different parts of the plain. The vegetation cover of the study area includes four types: wetland species, hygrophytes, terrestrial halophytes and psammophytes. Tamarix passerinoides, Lycium depressum, Seidlitzia rosmarinus, Atriplex leucoclada could be recommended as the species adapted to the climate and soil of the study area.
