Phytosociological Study in Quercus libani Oliv.’s Site by Analyzing Environmental Factors in West Azerbaijan, Iran

Raza Basiri
In this study, Quercus libani Oliv.’s site in Sardasht has been studied phytosociologically. The vegetation has been carefully studied in Braun-Blanquet method. The relationship between environmental factors including topography and some of the most current physicochemical features of soil and plant associations was researched by means of multiple discriminant analysis. Based on AFC and CAH methods, 8 associations and 1 sub-association were achieved including: Trifolio stellati-Quercetum brantii, Pistacio atlanticae-Quercetum brantii, Violo modestue-Quercetum brantii, Trifolio campestri-Quercetum brantii, Quercetum brantii, Thalictro sultanabadensi-Quercetum libani, Quercetum libani-acerotosum cinerascens, Quercos boissieri-Quercetum libani and Quercetum libani. These plant associations belong to Quercetea persicae class and Quercetalia persicae order. The effective environmental factors in division of plant associations based on multiple discriminant analysis include respectively: pH, landform index, Terrain shape index and aspect.
