- In this study the effects of environmental factors on some vegetative characteristics of Quercus brantii was investigated in Kouh gachan, Ilam, West of Iran, using multivariate analysis. Therefore 64 sample plots with a size of 200 m2 were considered for measuring the vegetative parameters. Some environmental factors such as slope, aspect and soil depth were recorded in all sample plots. The Detrended Correspondence Analysis (DCA) was used to investigate the relation between vegetative parameters and environmental factors. Redundancy analysis (RDA) analysis was also used to interpret the results. The results of DCA analysis showed that the effect of environmental factors on vegetation cover is significant. Slope had the smallest and the soil depth had the biggest effect on vegetative characteristics of Quercus brantii. The results also confirmed the usage of RDA analysis for investigating the relationship between environmental factors and vegetative characteristics.
