Abstract

This study was carried out in the forests of Dodangeh either sides of Shirin Roud river, in 80 km from south of Sari, to determine characteristics and structure of forest vegetation which has never been ecologically studied. Vegetation types of the area were determined through recording different vegetation parameters and TREE MEASUREMENTS and by calculating Importance Value (IV) and IV ranks. Furthermore, VEGETATION PROFILE of the forest along a natural transect of south-north was drawn to reveal floristical and structural characteristics of the forest. Vegetation parameters and TREE MEASUREMENTS used in the analysis were recorded in 15 plots of 40*40 m in either east and west of the river. TREE MEASUREMENTS including Diameter at Breast Height (DBH), total height, height of tree to the first branch crown height, crown diameter and form of tree, were recorded for the trees of more than 10 cm of trunk diameter by using measure tape, diameter tape and clinometers. Position of the trees in each plot was determined by recording the distance from a tree to a given x and y coordinates. Based on vegetation structure, altitude and other physiographic characteristics of the study area as well as field investigation, we recognized two elevation units of 790 1100 and 1100-1700 meter above sea level. The dominant forest type in both east and west of the first group was Fagus orientalis-Carpinus betulus-Parrotia persica. In the second group, vegetation types of Fagus orientalis-Carpinus betulus-Alnus subcordata-Tilia platyphyllos and Fagus orientalis-Alnus subcordata-Carpinus betulus were dominant in the east and the west of the river, respectively. Considering IV ranks on all species in all plots, the Fagus orientalis-Carpinus betulus-Acer velutinum forest type was dominant in both aspects of elevation range of 790 to 1700 m. VEGETATION PROFILEs of both aspects were also drawn and depicted in the paper. The information obtained on this valuable ecosystem could help better management and sustainable development of the forest area.
