Abstract

This study was carried out on vegetation Gisoum forest reserve with 171 hectares Area located in 14 km to Resvanshar city, Gilan province, to examine the structure and composition of the forest vegetation. In the beginning topographic map of the area with the scale of 1: 10000 was prepared and the study area was delimited. Transect- quadrate method of sampling in 44 quadrates of 400 m2 was used to record the floristic. some vegetation parameters viz. Density and diameter at breast height (DBH) for trees (upper story vegetation) as well as cover-abundance for under story vegetation were recorded, respectively. The raw data were entered to Excel program package to perform the necessary data processing. Life form spectrum of Raunkiaer, the dominant vegetation type of the area based on important value and vegetation construction base on frequency classes, Also their CHOROLOGY were determined. The study of floristic list showed 76 species belong to 66 genera and 45 families that Asteraceae and Rosaceae with 5 species were the families with the highest number of species. Investigation on geographical distribution of plants species showed 44 percent belong to Europe –Siberian region. Studying of plant life forms by Raunkiaer method showed that phanerophytes with 35.5 % and hemi cryptophytes with 27.6 % are the most frequent life forms. Dominant vegetation type base on important value index was Buxcus-Parrotia. Also the evaluating of vegetation structure base on frequency class showed abundance-distribution was irregulars in under story and regular in upper story vegetation.
