Abstract

Following a field reconnaissance, three elevation levels (1800, 2000 and 2200 meters above see level) were recognized to investigate natural REGENERATION QUANTITY AND QUALITY of OAK (Quercus brantii) stands at Hyanan forest in Ilam province. Forest inventory was done with stratification sampling methods choosing 2000 m2 plots to record forest stands and 400 m2 plots to record REGENERATION (five plots at each stratum). Variables in macro-plot were included tree diameter (DBH), total height, stem height, maximum and minimum diameter for all trees in the plot and quality of OAK trees and tree species diversity. Also, number of seedling was counted in each micro-plot. Analysis of variance (ANOVA) and Duncan test were used statistically to compare the results among three elevation levels. The results indicate that the site of interest exhibits an uneven-aged stand structure. The forest site located on 1800 meters elevation exhibits the most suitable stands considering tree density, diameter structure, and tree quality. In respect to the average height of trees and REGENERATION rates, stands located in 2000 meters were significantly better than stands of two other elevation levels. Also, the highest rates of REGENERATION establishment have been subsequently observed under shade and shelter of: (A) trees and bush, (B) shrubs and big stones; and the lowest rates were established on open areas. The results suggest that the seedling need shade at the early stage of growth.
