| Abstract | ||||
| (Pinus brutia. Ten) trees grows naturally in the Atrush region, on a wide range location from 31ʹ36° - 51ʹC 36°N and a longitude ranging from 20ʹ 43° - 21ʹ 43° E and above sea level (728-1127) meters, and the average decline between(3.65% - 18.91%).These forests are renewable natural resources and must be preserved, sustained and managed efficiently, and these require the preparation of basic preliminary data on what exists from these resources and how they interact with each other in the forest ecosystem. In this study, the coordinates of the sites of the spread of trees were measured in (20) samples in the research area.Three variables represented by the base area, height, diameter at chest height, crown diameter, crown height and other variables that measured for three stages of the life of trees that are initiatives (height less than 2 m), seedling (height more than 2 m and diameter less than 10 cm) and diameter(10 cm and more).Results showed that the pattern of distribution of communities is dominated by random pattern and for most distances and for three stages of life (initiatives, seedling and trees) with a little aggregate pattern with some sites heading to a state of regulator when there is little competition between species or between different stages of life, especially at locations in the east and northeast and long distances with the exclusion of Oak, (Quercus spp) from Pinus brutia, the random distribution pattern was reduced to about 50% and the melee went to the aggregate pattern. | ||||
