Abstract

In order to determine the seeding cycle of beech tree in Kelardasht, Sangdeh and Gorgan forest of Caspian region 96 dominant tree were selected. Quality and quantity measurement on these trees was conducted and then all of these trees were felled down. From each tree one disc was cut above of the ground. These discs were analyzed and measurement such as annual diameter growth rate done on these disc. The results of this study are follow.1-two type of seeding cycle (heavy and light) was detected in beech trees.2- The minimum age of seeding is about 30 years and at this age LIGHT SEEDING usually starts.3- The HEAVY SEEDING begins at the age of about 60 to 75 years.4-in single site different seeding cycles observed during the living of trees.5-The LIGHT SEEDING accrues in 1 to 3 years periods but HEAVY SEEDING accrues in 3 to 9 years intervals.6-Regeneration of natural forest depends on LIGHT SEEDING cycles.7-This study revealed that natural regeneration must be based on LIGHT SEEDING, therefore forestry practices increases the harvesting cycles from 5 years to 10 or more years in implementation of forestry Project especially in seeding felling in shelter wood cutting systems.
