Spatial distribution pattern of oak and almond trees on Chahartagh forest reservation site.

Investigation of the spatial pattern of plant communities is essential to understanding many problems in forest ecology. Spatial patterns and spatial relationship of tree individuals with their neighbors is a practical approach to selecting the best acts for the conservation, sustainable management of resources and, the key to interpreting ecological relationships of the plant community. The purpose of this study was to investigate the spatial patterns of oak and almond trees with the Ripley's K function. This study was carried out in 50-hectare area of the Chahartagh forest reservation site by measuring distance and azimuth for all tree individuals. The results showed that the distribution patterns of oak species to 235 meters and almonds species to 115 meters were statistically significant and clustered.
