Georgia country - Geography

In the north, Georgia has a 723km common border with Russia, specifically with the Northern Caucasus federal district. The following Russian republics/subdivisions - from west to east - border Georgia: Krasnodar Krai, Karachay-Cherkessia, Kabardino-Balkaria, North Ossetia-Alania, Ingushetia, Chechnya, Dagestan. Georgia also shares borders with Azerbaijan (322 km.) to the south-east, Armenia (164 km.) to the south, and Turkey (252 km.) to the south-west.

Mountains are the dominant geographic feature of Georgia. The Likhi Range divides the country into eastern and western halves. Historically, the western portion of Georgia was known as Colchis while the eastern plateau was called Iberia. Due to a complex geographic setting, mountains also isolate the northern region of Svaneti from the rest of Georgia.

The Greater Caucasus Mountain Range separates Georgia from the North Caucasian Republics of the Russian Federation. The southern portion of the country is bounded by the Lesser Caucasus Mountains. The main Caucasus Range is much higher in elevation than the Lesser Caucasus Mountains, with the highest peaks rising more than 5,000 meters (16,400ft.) above sea level. The highest mountain in Georgia is Mount Shkhara at 5,201 meters (17,059 feet), and the second highest is Mount Janga (Jangi-Tau) at 5,051 meters (16,572 feet) above sea level. Other prominent peaks include Kazbegi (Kazbek) at 5,047 meters (16,554 feet), Tetnuldi (4,974m./16,319ft.), Shota Rustaveli (4,960m./16,273ft.), Mt. Ushba (4,710m./15,453ft.), and Ailama (4,525m./14,842ft.). Out of the abovementioned peaks, only Kazbegi is of volcanic origin. The region between Kazbegi and Shkhara (a distance of about 200 km. along the Main Caucasus Range) is dominated by numerous glaciers. The Lesser Caucasus Mountains are made up of various, interconnected mountain ranges (largely of volcanic origin) that do not exceed 3,400 meters (approximately 11,000 feet). Prominent features of the area include the Javakheti Volcanic Plateau, numerous lakes, including Tabatskuri and Paravani, as well as mineral water and hot springs.

Major rivers in Georgia include the Rioni and the Mtkvari.

Georgia country - Landscape

The landscape within the nation's boundaries is quite varied. Western Georgia's landscape ranges from low-land marsh-forests, swamps, and temperate rain forests to eternal snows and glaciers, while the eastern part of the country even contains a small segment of semi-arid plains characteristic of Central Asia. Forests cover around 40% of Georgia's territory while the alpine/sub-alpine zone accounts for roughly around 10% of the land.

Much of the natural habitat in the low-lying areas of Western Georgia has disappeared over the last 100 years due to the agricultural development of the land and urbanization. The large majority of the forests that covered the Colchis plain are now virtually non-existent with the exception of the regions that are included in the national parks and reserves (i.e. Paleostomi Lake area). At present, the forest cover generally remains outside of the low-lying areas and is mainly located along the foothills and the mountains. Western Georgia's forests consist mainly of decidious trees below 600 meters (1,968 ft.) above sea level and comprise of species such as oak, hornbeam, beech, elm, ash, and chestnut. Evergreen species such as box may also be found in many areas. There are significant concentrations of endemic species of plants as well. The west-central slopes of the Meskheti Range in Ajaria as well as several regions in Samegrelo and Abkhazia are covered by temperate rain forests. Between 600-1,500 meters (1,968-4,920 ft.) above sea level, the decidious forest becomes mixed with both broad-leaf and coniferous species making up the plant life. The zone is made up mainly of beech, spruce, and fir forests. From 1,500-1,800 meters (4,920-5,904 ft.), the forest becomes largely coniferous. The tree line generally ends at around 1,800 meters (5,904 ft.) and the alpine zone takes over, which in most areas, extends up to an elevation of 3,000 meters (9,840 ft.) above sea level. The eternal snow and glacier zone lies above the 3,000 meter line.

Eastern Georgia's landscape (referring to the territory east of the Likhi Range) is considerably different from that of the west. Although, much like the Colchis plain in the west, nearly all of the low-lying areas of eastern Georgia including the Mtkvari and Alazani River plains have been deforested for agricultural purposes. In addition, due to the region's relatively drier climate, some of the low-lying plains (especially in Kartli and south-eastern Kakheti) were never covered by forests in the first place. The general landscape of eastern Georgia comprises numerous valleys and gorges that are separated by mountains. In contrast with western Georgia, nearly 85% of the forests of the region are deciduous. Coniferous forests only dominate in the Borjomi Gorge and in the extreme western areas. Out of the deciduous species of trees, beech, oak, and hornbeam dominate. Other decidious species include several varieties of maple, aspen, ash, and hazelnut. In the upper Alazani River Valley, there are yew forests as well. At higher elevations above 1,000 meters (3,280 ft.) above sea level (particularly in the Tusheti, Khevsureti, and Khevi regions), pine and birch forests dominate. In general, the forests in eastern Georgia occur between 500-2,000 (1,640-6,560 ft.) meters above sea level, with the alpine zone extending from 2,000/2,200-3,000/3,500 meters (roughly about 6,560-11,480 ft.). The only remaining large, low-land forests remain in the Alazani Valley of Kakheti. The eternal snow and glacier zone lies above the 3,500 metre (11,480 ft.) line in most areas of eastern Georgia.
