The recognition of the plant coverage of an area is the basis of ecologic studies; and plays an
important role in the environmental life management. The goal of this study is introducing the trees and shrubs
species in beech sites of Kojour as plant units. In this study, at first, the land form units were divided on
topography maps (1:25000). Then at each land unit, the trees and shrubs were recognized through forest course,
and a circular plot (1000 m2) was selected regarding to stand conditions (in total 31 plots). According to
physiognomic conditions the plant units were defined. The results were shown as types of the trees and the
shrubs at each area regarding the altitude, aspect and percent of slope. The results indicate that the distribution
of spices, the mixture of the trees and the forest types of beech sites are affected by ecological factors. There
are better conditions in the forest stands, at higher altitude. The high quality spices are found in the northern
aspects because of the suitable humidity where as destroyed stands are seen in the southern aspects. Going far
from the villages, the forest types change by ecological factors.
