Abstract

In order to survey the effect of different environmental factors on oak (Quercus castaneifolia L.) NATURAL REGENERATION, 20 macroplats of 1000m2 were selected randomly at different sea level in Sourdar forests (north of IRAN). In each macroplat,9 microplots of 12.5 square meter (in total 180 microplats) were selected at 4 different directions. The characteristics measured included: cutting method, altitude, diameter at breast height, total height, crown length, crown form, stem quality, crown canopy, steep, direction, ground vegetation, soil, species, number and quality of seedling and sapling.The results of the present research showed that crown canopy and crown asymmetry did not have a significant relationship with oak NATURAL REGENERATION. There were no remarkable relationship between healthy mother tree and unhealthy oak regeneration, because livestock and human had substantial effect on unhealthy seedling and sapling. As a whole, the best oak regeneration occurs in low elevation parts, southern aspects, more slightly slopes and middle age phases. Likewise, oak had better regeneration in deep, humid and clay soils.
