Some factors affecting the natural generation of Pinus pinea L. stand in Dahr Kheribat site - Lattakia

The study was achieved in 2014-2015 at Dahr Khribat stone pine forest, Latakia. to determine the factors affecting the natural regeneration of the stand. The results of climate studies indicated that the region is located in the semi-wet climate floor with a mild winter as the average of rainfall thermal coefficient reached (Q2 = 72.01). The study showed that the low productivity of cones (20 kg con / tree) was one of the limiting factors of natural regeneration. The trees high density (462 tree / ha), led to a decrease in tree diameter at breast level (30 cm) and low coronary size (320.2 m3). Seed germination was not affected by illumination periods, while salinity levels led to a significant decrease in germination from 90% at control to 19% at 0.5 mol / l. All of one year old sapling or seedling were dead during summer months, while more than 90% of two years old cultivated sapling, survived in all treatments, but no significant differences among them.

Studying Natural Vegetation after 1991 Fire in Kassab – North of Lattakia - Syria

The aim of this research was to investigate the changes of vegetation and regeneration of plant species in Kassab forests after 1991 fire. The study area is located in the North western part of Syria in the middle of Al-Baier and Al- Bassit forests to the North of Latakia. Thirty five plant surveys (Relevé) were carried out in the study area during 2009 according to Braun-Blanquet method included the burned area and the nearby locations of non-burned forest. By comparing the plant surveys (Relevé), results showed good regeneration of most plant species that were in the study area before the fire. Three forms of vegetation were distinguished in the study area: 1 - The areas where dominance is shared between Pinus brutia Ten. and Quercus cerris L. subsp. pseudocerris (Boiss.) Chalabi. 2 - Areas dominated by Pinus brutia Ten. with accompanying species from Eu-Mediterranean zone and supra Mediterranean zone. 3 – Areas where Pinus brutia Ten. and Quercus cerris L. subsp. pseudocerris (Boiss.) Chalabi are partly or completely absent, and dominated by shrubs and grass species.
