Forests regeneration is considered as an important and urgent need in all their existence areas for protecting environment and supporting biodiversity. Accordingly, the research aims to study the most important influencial factors in natural regeneration in Jabatta Al Khashab wood reserve and recommend requirements for promoting these societies to an apogee, define the hindering obstacles, and to set adequate plans to protect and develop this area. For realizing this goal, several botanic field inspections (Relevés) were performed through the time span lasted from May 2010 March 2011, through which, natural regeneration process of different botanic species was followed up in the reserve, in particular woody flora such as both oak species trees (Quercus sp), neapolitan (Crataegus azarolus) terebinth, broom and others. The research revealed a very weak natural regeneration of oaks (Quercus sp) in general and its attendant tree in particular. It was realized that major role in that is attributed to unnatural factors namely environmental tourism and diversified human activities. The research revealed that diversified human activity in the area, though declaring it as a natural reserve, is not only the regeneration hinderer but even the regeneration inhibitor. This activity has an explicit impact on botanic grassy and woody species regeneration decline and species population retreat due to overgrazing, overloading, random harvesting of nourishing and herbal plants, fire lighting in the reserve, picnickers' activities, and other factors.

Research summary
تتناول هذه الدراسة التجدّد الطبيعي في محمية جبّاتا الخشب والعوامل المؤثرة فيه. يهدف البحث إلى دراسة أهم العوامل المؤثرة في التجدد الطبيعي في غابة جبّاتا الخشب، واقتراح الحلول المناسبة لتعزيز هذا التجدد وتحديد المعوقات. أجريت الدراسة من خلال عدة كشوف نباتية بين مايو 2010 ومارس 2011، حيث تم متابعة عملية التجدد الطبيعي لمختلف الأنواع النباتية في المحمية، وخاصة الأشجار مثل السنديان بنوعيه والزعرور والبطم والوزال. أظهرت النتائج ضعفاً كبيراً في التجدد الطبيعي للسنديان والأشجار المرافقة له، وعزت الدراسة هذا الضعف إلى العوامل غير الطبيعية مثل السياحة البيئية والنشاطات البشرية المتنوعة. أوضحت الدراسة أن النشاط البشري المتنوع في المنطقة، رغم إعلانها كمحمية، هو المانع الرئيسي أمام التجدد الطبيعي، مما أدى إلى تراجع أعداد الأنواع النباتية سواء كانت عشبية أم شجرية. اقترحت الدراسة عدة توصيات لحماية وتطوير المنطقة، مثل منع الرعي الجائر، مراقبة عمليات قطف الثمار، وضع لوحات إرشادية، وتسيير حراس لضبط المخالفات.
Critical review
تعتبر هذه الدراسة خطوة مهمة لفهم العوامل المؤثرة في التجدد الطبيعي في محمية جبّاتا الخشب، إلا أنها تفتقر إلى بعض الجوانب التي يمكن أن تعزز من نتائجها. على سبيل المثال، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تحليلاً أعمق للعوامل المناخية وتأثيرها على التجدد الطبيعي. كما أن التركيز على النشاطات البشرية كان جيداً، لكن لم يتم تقديم حلول عملية كافية لتقليل هذه النشاطات. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر دقة إذا تم استخدام تقنيات حديثة مثل التصوير الجوي أو الاستشعار عن بعد لتحديد المناطق الأكثر تضرراً. بشكل عام، تعتبر الدراسة قيمة ولكنها تحتاج إلى تحسينات في بعض الجوانب لتكون أكثر شمولية ودقة.
Questions related to the research
  1. ما هي العوامل الرئيسية التي تعيق التجدد الطبيعي في محمية جبّاتا الخشب؟

    العوامل الرئيسية التي تعيق التجدد الطبيعي تشمل النشاطات البشرية مثل الرعي الجائر، الوطء الشديد، عمليات الجمع العشوائي للنباتات، وإشعال النار في الغابة.

  2. ما هي التوصيات التي قدمتها الدراسة لحماية وتطوير محمية جبّاتا الخشب؟

    التوصيات تشمل منع الرعي الجائر، مراقبة عمليات قطف الثمار، وضع لوحات إرشادية، تسيير حراس لضبط المخالفات، ومنع إشعال النار في الغابة.

  3. كيف تم إجراء الدراسة لتحديد العوامل المؤثرة في التجدد الطبيعي؟

    تم إجراء الدراسة من خلال عدة كشوف نباتية بين مايو 2010 ومارس 2011، حيث تم متابعة عملية التجدد الطبيعي لمختلف الأنواع النباتية في المحمية.

  4. ما هي الأنواع النباتية التي تم التركيز عليها في الدراسة؟

    تم التركيز على الأنواع الشجرية مثل السنديان بنوعيه، الزعرور، البطم، والوزال.

This research aims to classify the Bryopsida species (Mosses) at Jibata Al- Khashab reserve in Al-Qunaitera, through the project of the Biodiversity in Syria. The species which had collected and studied morphologically according to the description of the parts (Gamatophyte and Sporophyte) by using the optical microscope, magnifying glass and key words for each species, classified and annexed by photographs. The result of this study identified five species of Bryopsida were indentified, three of them belong to Acrocarpi Mosses group and two of them belong to Pleurocarpi Mosses group.
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.
This study conducted at Deir Al-Hajar Station during the season 2010-2011 to describe the lactation curve of Shami cattle and determine factors affecting its shape compenents. 1120 records of 356 Shami cows collected between 1997 – 2010 were used. Data were subjected to general linear model, and the analysis of variance used to determine the effect of factors. Duncan test was used to compare the means using SAS system (1996) and Incomplete gamma functions were used to estimate the parameters of lactation curve (a, b and on the basis of daily yield of milk. Results indicated that the average values of the gamma parameters were 2.14 ± 0.01 kg for a (beginning of milking ), 0.61 ± 0.02 kg for b (increasing milk production up to peak) and - 0.23± 0.01 kg for c (decreasing milk production from peak to dry). The effect of calving year was significant (p<0.01) on a, and (p<0.05) on b and (p<0.001) on c. The effect of age at calving and sex of calf was significant (p<0.01) on a but non significant on b and c. Season of calving, parity, and interaction between age and parity was not significant on all parameters. It was concluded that improving the productive performance of Shami cattle, requires applying a long term genetic improvement program to select the best herd.
A random sample of the kinds of bread consumed in the coastal region during the years of research was taken, the percentage of fiber and protein was calculated, and the effect of the mixture approved on an annual basis in mills on purveyance flour content of fiber and protein was studied. The study showed the important role of the mixture, where the percentage of fiber increased from (1.06%) in 2009 to (1.61%) in 2010, and the percentage of protein increased also from (11.36%) in 2010 to (13.90%) in 2012. The results show that there are some, but not all, governmental mills which add soft bran fiber and protein-rich flour, taking into consideration the impact of technological processes applied throughout the stages of manufacturing bread, and in particular the stages of fermentation and broil.
