Abstract

The main purpose of this study was to determine the quantitative and qualitative characteristics of maple trees in the plantation of Lomar Asalem,. The measurement and comparison of quantitative and qualitative characteristics of maple trees and regeneration status in plantation and natural forests and compared to other species is concerned. This study was conducted in Maple plantations at the age of 25 based on a systematic random sampling method with 30 sample plots of 400 m2. The results of t-test showed a significant difference between the number of trees per hectare, basal area, volume, slenderness coefficient and diameter growth of the maple trees in the two areas. However, there was no significant difference in the mean height of trees in the two regions and their height growth. In terms of qualitative characteristics, there was no significant difference in the trunk health of maple trees in the two areas. However, there was a significant difference at the level of 0.05 compared to the trunk form of these trees between the two areas. Significant differences were observed in the crown symmetry of the maple trees in the two areas, but there was no significant difference in the crown health and vitality of these trees. Regeneration density in the natural forest was higher than in the plantation. While the frequency of healthy seedlings and single trunk seedlings in the plantation was significantly higher than natural forest. Plantation in the area had a suitable condition in terms of quantity and quality than natural forest.
