Comparison of Natural Regeneration Establishment in the Forest Stands under Management

With regard to desired natural regeneration establishment that it is the goal of selection systems. The role of tree and group selection silvicultural systems on the quantity and quality of natural regeneration was conducted at four site of forest. First, 100 circular sample plots has been selected by use of random systematic inventory. Then into the each plots nine micro-plots defined. The results of one way analysis of variance, multiple ranges Tukey-HSD test and Chi square test of seedling showed that there is significant difference in the level of 0.05 between mean of seedlings number, mean of carpinus seedlings number, percent of the health, shining, even and vertical seedlings in tree selection and group selection systems. So in the establishment of natural regeneration the quantity and quality of natural regeneration in tree selection system is more desirable than group selection system. In the bigger cutting sites the stand comes out of climax conditions and in the result it will reduce the establishment percent of original species regeneration. With regard to the desirable results of tree selection system it is necessary to recommend that tree selection system should be write down in forest management plans description.
