Abstract

The domain of growing Lebanon oak covers around 106316 hectares (%24) of northern Zagross rests. Even though forest service in the Organization of Forests and Rangelands considers Zagross forest as protected, yet continuing exploitation as wood and fodder ley local population to meet their basic daily needs is quite usual and the forest service has not so far been able to put an end to this. As is necessary to manage forests with due consideration to people's rights and activities rather than denying them, the forest service has adopted a policy of management in which active participation and cooperation of local people is fully token into account. Considering the new policy along with applying the new regulations, to manage forests as regards timely harvesting as well as reproduction based on stand age structure, collection of information on tree DIAMETER GROWTH seems to be a must and a key part of management.this research was conducted to estimate the DIAMETER GROWTH of the trees growing in Havareh khole forest area to present a model of forest regulation in the father future studies. Thirty four pairs of increment cores of Lebanon oak were randomly selected through line sampling. Also 7 trees were cut to be used for further and more precise measurements. Current annual DIAMETER GROWTH in these trees was measured to be 3.5 mm/year with relative sampling error of 10.7% at 95% confidence level. There made it 12 cases of samples that made it possible to get the precise age of the trees. Based on these measurements age-diameter regression line was developed to help find the age of trees through diameter measurements.
