يمثل هذا البحث توصيفاً مورفولوجياً لأنواع الحزازيات الحقيقية في محمية جباتا الخشب بمدينة القنيطرة في إطار مشروع التنوع الحيوي في سورية، إذ جمعت العينات النباتية من المحمية، و درست مورفولوجياً اعتماداً على وصف أجزاء النبات العروسي و النبات البوغي مورفولوجياً اعتماداً على وصف أجزاء النبات العروسي و أرفقت بالصور التوضيحية، و بنتيجة هذه الدراسة حددت خمسة أنواع تابعة لصف الحزازيات الحقيقية تنتمي ثلاثة منها إلى مجموعة الحزازيات قمية الإثمار في حين ينتمي نوعان إلى مجموعة الحزازيات جانبية الإثمار.
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 aims to describe the morphological and anatomical of
Bryopsida species in the Bassel ALASSAD forest, through the project of the
Biodiversity in Syria. Five species of Bryopsida were identified, four of them
belong to “Acrocarpi Mosse
s group” and one belong to “Pleurocarpi Mosses
group”.
These species were studied morphologically according to the description of
the parts “Gametophyte”,
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 regenera
tion 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.
The Studay was aimed at surveying the plant species growing in Al
Qunaitera region, their dynamic distribution, environmental characteristics
and economic values.
Atotale number of 268 species were found belonging to 170 genera at 46
families.
Only two of the founded species weren’t reported by Mouterde in his flora
of Syria.
Primary survey study of the Bryidae has been reported in this
research, whithin range of Biodiversity and Ecodiversity in Syria.
We found ٢٩ species, which has been identified, and defined their
distribution in different places in the north and so
uth of the country,
also the identification of the most important peristome as a scales of
classification, the nature of growth substrates, has been investigated.
Three of these Bryidae recorded for first time which is: Tortella
tortuosa, Grimmia laevigata, Bryum caespiticium.
The present research aimed to define the training needs of educational
supervisors in Syrian Arab Republic, as seen by educational supervisors.
In addition, to know whether there is a difference between the opinions of
the supervisors about their training needs according to the variables of
gender, scientific and educational qualifications, and their experience in
educational supervision.
