Abstract

Background and Objectives: The spatial distribution of Iranian oak trees plays an important role in the dynamics of the western forests ecosystems of the country and their optimal management. In general, the spatial distribution of phenomena is divided into three random, regular and clumped modes. The forest has two horizontal and vertical structures. The horizontal structure of the forest is surface distribution of trees in the forest area and the vertical structure is the height distribution of trees in the forest stand. One of the important characteristics of forest stands is the horizontal distribution of trees. Iranian oak is one of the main species of Zagros forests. Therefore, understanding the distribution pattern of this species can be one of the important factors in preserving, rehabilitating and developing forests of the region. Materials and Methods: In line with this research, the area of 30 hectares was selected from Olad-Ghobad forests in the west of Lorestan province, in Kohdasht city. To conduct field operations each hectare of the study area was selected as a 1 ha sample plot in which, based on the complete sampling, the diameter of each tree was measured. Then, by determining the initial station at the surface of each sample plot and measuring its geographical coordinate using the GPS, the coordinates of all oak trees were determined by measuring the azimuth and distance of the trees from the initial stations based on Cartesian trigonometric calculations. Then the measured trees were divided into three diameter classes of low, medium and high diameter. Investigation of spatial pattern of Iranian oak trees was done using one-variable function of O-ring statistic. Results: The results showed that the spatial pattern of the trees due to the creation of the coppice shoots and sprouts and also the higher density of coppice forests in comparison to high forests at short distances from the base tree (usually 20-25 m) is clumped, and then with the scale enlargement in some geographic directions (north and northwest directions) is regular due to the human interventions and the removal of regeneration by livestock grazing. Conclusion: Considering that in most of the studied area, the distribution pattern is cluster therefore management plans and forestry interventions should be oriented so that the pattern of distribution is driven towards the cluster pattern. The results can be useful in designing planting patterns.
