Juniperus excelsais one of the specific tree species in the mountainous areas of Iran. It forms the mountainous forests of Irano-Turanian vegetation region. Despite the considerable spread ofJ. excelsain Iran, there is no detailed and valid published study on the phytosociology of Iranian juniper stands. The aim of this research is to identify these associations and their characteristics in Alborz mountains in the north of Iran. To this goal, a set of data including floristic data according to Braun-Blanquet method, and important environmental characteristics, were collected. To classify the vegetation, TWINSPAN was used and phytosociology tables were analysed with JUICE software. Diagnostic species were determined by measuring the degree of fidelity and using statistically meaningful measurements. According to the results, the vegetation was classified into six associations and five subassociations. Among them areCotoneastro nummulariis-Juniperetum excelsaeass. nov.,Lonicero ibericae-Juniperetum excelsaeass. nov.,Rhamno pallasii-Juniperetum excelsaeass. nov., Rhamno p.-Juniperetum e. ajugetosum chamaecistisubass. nov.,Rhamno p.-Juniperetum excelsae gypsophiletosum aretioidissubass. nov.,Amygdalo lycioidis-Pistacietum atlanticae hymenocratretosum bituminosorisKashipazha et al. 2007,Feruletum ovinaeass. nov.,Artemisio aucheri-Astragaletum veriAsri 2004, andArtemisio aucheri-Onobrychidetum cornutaeass. nov. The introduced juniper associations were placed in classJunipero-PistacieteaZohary 1973 and orderJuniperetalia excelsaenov. [ABSTRACT FROM PUBLISHER]
