A phytosociological research on the surroundings of Sürgü Dam (Sürgü/Doğanşehir/Malatya), Eastern Anatolia, Turkey

The study area is located within the boundaries of Sürgü town and belongs to Doğanşehir district of Malatya province in Eastern Anatolia Region. The study area in the Iran-Turan phytogeographic region is under the influence of a continental Mediterranean climate, which is dry in summer and very cold in winter. In the vegetation study carried out according to the Braun-Blanquet method (1932), seven syntaxa (associations) were identified, of which two belong to degraded forest vegetation, three belong to steppe vegetation and two belong to riparian vegetation. All of the syntaxa are new for the scientific world. The degraded forest associations are Thymo kotschyani– Juniperetum oxycedri ass. nova and Securigero variae– Quercetum cerridis ass. nova. The steppe associations are Gundelio armatae– Fumanetum aciphyllae ass. nova, Phlomido kurdicae– Astragaletum gummiferi ass. nova and Helichryso plicati– Polygonetum setosi ass. nova. The riparian associations are Rubo sancti– Salicetum cinereae ass. nova and Salici cinereae– Elaeagnetum angustifoliae ass. nova.
