This research aimed to study the natural regeneration of Pinus brutia in Qurdaha
region, and to determine the most important factors affecting the regeneration. 42 circular
samples were taken, the area of each sample was 400m2. The following measur
ements were
taken: geographic coordinates of each sample's centre, altitude, aspect, the slope, forest
litter thickness, the proportion of gravels, stones and rocks, tree, bushes and herb cover.
Forest inventories were achieved using Braun-Blanquet method. Which, the number of
sample seedlings, the seedling height, seedling diameter, the seedling age, burning trees
and alive trees of Pinus brutia were registered. The results showed a significant negative
effect of slope and a significant positive effect of herb cover, where the percentage of data
classification by the model was reached 74.4%, while the Nagelkerke R2value was 37%.
The negative effect of the slope comes from increasing the risks of soil erosion and the loss
in their nutritional elements. In contrast, the positive effect of herbal coverage is the
contribution to reducing the risks of summer drought that can be affect the seedlings.
