Abstract

This research aimed to study the natural regeneration of Pinus pinea L. in many regions in Lattakia, and to determine the most important factors affecting the regeneration. 60 circular samples were taken, the area of each sample was 400 m2. The results showed a significant positive effect of the height above sea level, and a significant negative effect on the percentage of rock exposures and a significant positive effect of herb cover. As the total capacity of classification and data forecasting was by the model 81.1%, as the Naglkerke R2 value was 54.4%. The positive role of herb cover in the increase in the number of natural rejuvenation seedlings, particularly in the sloping areas, through their contribution to protecting soil from erosion and securing the suitable cradle for the growth of seeds and seedlings of Pinus pinea .The negative role of rock discoveries is in the prevention of pine seeds from reaching the soil and its optimal growth. In terms of the role of the height from the sea in the studied sites, it was positive with the increase  in the height above sea level because of suitable climate factors for growth of seeds and seedlings regeneration and thus ensure continuity.

Key words : Pinus pinea L., Natural regeneration, Inventory, Slope, Herb cover, Syria.
