AN INTRODUCTION TO THE FOREST ASSOCIATIONS OF ELIKA ECOTON AREA, N. IRAN HASSAN NAZARIAN, AHMAD GHAHREMAN1, MORTEZA ATRI2 AND MOSTAFA ASSADI3
Abstract: Eco-phytosociological method with emphasis on physiognomic-floristic-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 Braun-Blanquet'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. ibericae-Carpinetum
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 ssp. hemisphaericae association, and Aceretosum monspessulanii
ssp. ibericii sub association. The phytosociological table was prepared and the
ecological factors of syntaxa were presented.
