i Greater Caucasus content
• Greater Caucasus is the major mountain range of the Caucasus Mountains.• The range is traditionally separated into three parts:Western Caucasus, from Black Sea to Mount ElbrusCentral Caucasus, form Mount Elbrus to Mount KazbekEastern Caucasus, form Mount Kazbek to the Caspian Sea
• In the wetter Western Caucasus, the mountains are heavily forested . In the drier Eastern Caucasus, the mountains are mostly treeless

XINALIQ - the highest village in Azerbaijan• Xinaliq is Azerbaijan’s highest mountain village, approximately 2,250 metres
above sea level. Xinaliq is in a stunning location not far from Shahdag, Azerbaijan’s highest peak, in the southeast ridge of the Caucasus mountains.

•Location It is located just north of Quba in the middle of the Greater Caucasus mountains that divide Russia and the South Caucasus. Khinalug is also the highest, most remote and isolated village in Azerbaijan and among the highest in the Caucasus.
•ClimateThis type is characteristic of the eastern sections of the Great Caucasus range and of the Small Caucasus mountain chain. The climate has continental features over most of the area: mean annual precipitation varies from 600 to 1000 mm. Due to the absence of refugia the zonation is relatively simple. The weather changes dramatically during summer and winter, ranging from −20 °C to 18 °C.

Subnivale vegetation of the Xinaliq regionSub-nival belt: The subnival zone represents the upper level of the alpine belt, almost devoid of soil cover. Only a few plants are found here and respectively only mono or bidominant plant communities. It is the highest zone that vegetation typically exists. This area is shaped by the frequent frosts that restrict extensive plant colonization. Vegetation: Vegetation is patchy and is restricted to only the most favorable locations that are protected from the heavy winds that often characterize this area.Mosses, cluster-forming plants and lichens that arise from an interaction between fungi and algae.
