Abstract

Three elevation levels (300, 850, and 1200 meters above sea level) of Nowshahr forests were chosen to investigate regeneration and qualities characteristics of OAK (Q. castaneifolia) stands. At each elevation level 10 macroplots (1000 m2) were allocated randomly and systematically. At each macro plot 12 microplots (1m2) were allocated along two diameters of the circle macroplots (nothern - southern and eastern - western) by three meters intervals. The growth parameters which were studied at each macroplots were diameter of OAK trees and other species; total height of OAK trees and crown height of OAK trees and OAK trees quality (stem twist, stem crokedness, stem smoothness, crown harmony and branching). Cover percent of herbal accompanied plants in each micro and macro plots were determined. The results showed that the best stands of OAK species in view of dominant height and regeneration was found at the medium level of elevation(850 m) where as the best in view of quality was found at the lowest level of elevation (300m) . It means that by increasing the elevation, the qualities of OAK stands were decreased. The soil type at 300 m and 1200 m elevation levels was brown autroph where as at 850 elevations level was classic brown. The soil depth at each soil type was considerable.
