Abstract:

Eco-phytosociological method with emphasis on physiognomicfloristic-ecologic criteria have been employed to study the vegetation of Elika ecoton area. The establishment places of releves were determined at random in each determined endogenic milieus. The concerned floristic-ecologic data of each releve was entered in the forms related to releves, using BraunBlanquet`s Composition Coefficients A-D and S. The data analysis was performed by using Anaphyto Software in F.C.A and A.H.C. methods. The following four formations were specified:(1) Linear arborescent formation in the river margin (class Salicetea) with Salicetum aegyptiacae association;(2) Forest formation that includes two classes which consist of class Quercetea with associations Aceretum cappadocicii, Querco petraeae ssp. IbericaeCarpinetum betulii, Pyro mazanderanicae-Carpinetum orientalis, Pruno spinosae-Crataeginetum meyeri, Ulmetum minoris, and sub association Ulmetum minoris-Hippophaetosum rhamnoidis, and class Quercetea macrantherae with association Quercetum macrantherae;(3) Calciphilous scrub formation (class Ephedretea) with Rhamno pallasii-Ephedretum majoris association;(4) Orophilous and coniferous wood formation (class Juniperetea) with Juniperetum communis spp. hemisphaericae association, and Aceretosum monspessulanii ssp. ibericii sub association. The phytosociological table was prepared and the ecological factors of syntaxa were presented.
