تتعرض المراعي الليبية للرعي الجائر المستمر الذي يلحق ضرراً كبيـراً بالغطـاء النبـاتي علـى المستوى الكمي و النوعي و من ثم على الإنتاج الحيواني. لتوضيح أثر الحماية في بعض خصائص الغطاء النباتي الطبيعي قورنت منطقتـان: منطقـة محميـة و أخرى غير محمية مجاورة لها تتعرض لرعي غير منظم.
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.

The research is carried in the Hsia declared Mountains protective area where grazing is prevented since 1970, according Resolution No. 289/T. Issued by the Ministry of Agriculture the area is about 6000 hectares . In 2009 it was announced as nature reserve ( Resolution No. 209/T area of about 14000 hectares).
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 forest
s 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.
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.
He studied the effect of conservative and traditional agriculture on some different soil properties by digging soil sections in five fields belonging to the Agricultural Scientific Research Center in Salamiyah, the General Authority for Scientific Agricultural Research during the 2015 and 2016 seasons.
This study aimed to identify the most important factors affecting dates
production, in Wadi al Shati, Libya by estimating indicators of economic
efficiency of the resources used to measure the impact of each of the
components used in date producti
on. The field study indicated that the most
important productive inputs affecting significantly crop production (dates)
were number of trees, the quantity of fertilizer, water quantity and the number
of employment and expertise at different moral levlss. This has proven to be a
significant variables at different moral levels. The results also showed that the
elasticities of Wadi al Shati villages and the beach were positive and operating
in the first phase of increased production to reach about 0.847 and reflect the
return of diminishing capacity.
