منطقة الشيخ بدر التابعة لمحافظة طرطوس التي لا تتعدى مساحتها 20 ألف هكتار تحمل تباين طبوغرافي واضح و قد أظهرت نتائج البحث وجود تباين في التنوع النباتي من خلال ثلاث مستويات من الارتفاع عن سطح البحر .
Al- sheikh Bader is a small region , its land doesn’t exceed 20000 hectares , which has a significant variation in the topography .The results of this study in this region showed a variation in the vegetation of biodiversity within three scales of sea level.

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.
Biodiversity of wild relatives of Cataegus were studied in North-West region
of Damascus countryside located between latitudes 33.36 -33.58 N and
longitudes 35.58-36.39 E including 7 sites and 21 subsites ranging from
Zabadane to Alnabk. Results s
howed that the most of the individuals in the
search area belonging to C. azarolus and var. aronia and rare individuals ere
found to belong to C. monogyna. The study on the level of intraspecific
variability showed the presence of of three taxanomic groups, each had been
characterized with morphological and environmental qualities.The study also
pointed to the where of these species and their different types are located and to
the exist of corrlation between environmental factors and morphological
variables.
This study is considered a newly addition and continuous survey to
Ascomycetes and Basidiomycetes which are importance in Barada basin
(Damascus district), it basically aims at knowing fungal biological communities
at framework of biodiversity and
ecological diversity in Syria. The study
extended from ١٩٩٦ to ١٩٩٩ years.
Researchers in this study confirm that there are representatives of ١٠
families out of which ١٦ genera has been specified which are distributed to ٢٦
species (٢٤ of them have been specified), and representatives of ١٣ families out
of which ١٨ genera has been specified which are distributed to ٢٧ species. The
places of spreading of each of them in its medium, most important
characteristics, which allow to distinguish it have been referred to, as well as to
the main practical importance, which describes it regarding the nutritive value
or to do environmental roles.
The Libyan pastures have been subjected to continuous overgrazing, which
inflicts a great deal of damage to the vegetation cover, on both quantitative and
qualitative levels, as well as to the live-stock production.
To clarify the effect of protection on some characteristics of the natural
vegetation cover, two regions have been studied: A protected region and
another adjacent unprotected region, which is subjected to irregular grazing.
Syrian Steeps has formed the most important ecosystem in
Syria ,in particular on both side , biodiversity vegetation and
wildlife. Despite of this fact, the structure of communities have
been changed by many effects ,thus Syrian steeps has lost it
s
balance .This study aimed to analysis the impact of topography
on characteristics of communities , We found 38% of variance
return back to elevation and landscape ,specially between the
low sites ( often Depression , valleys and Terraces ) and the
high sites (often summit of mountains and plains).
