Abstract

In this study some characteristics of an unmanaged natural stand were measured and surveyed in two sampling periods as long as eight years in Kheiroud forest. Results showed that about 9.7 percent of all trees was fallen, 6.5 percent of trees were dried, 2.6 percent of all trees were embowed and crown of 1.6 percent of trees was broken during the period. Also the most fallen trees were occurred in low diameter categories (10 and 20 cm). Slenderness coefficient studies in the first period suggest the possibility of falling the trees in the future. Results showed that there is a negative significant correlation between HEIGHT OF CROWN and total height in first period and a positive correlation between HEIGHT OF TRUNK and total height. These relations in second period are inversed. In the surveying of relationships between TRUNK WITH BRANCHES and without branches in all specie, it is determined that TRUNK WITHOUT BRANCHES height in relation to TRUNK WITH BRANCHES is more obvious. The number of fallen and dried trees in the stand and the situation of the trees in diameters classes imply on needing of stand thinning. Otherwise, continuing of the stand destroying and increasing number of unhealthy trees will not be avoided.
