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/subalpine 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 because of 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 (e.g. Lake Paliastomi 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 deciduous trees below 600 meters (1,969 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. Ca. 1000 of all 4000 higher plants of Georgia are endemic in this country.
The west-central slopes of the Meskheti Range in Ajaria as well as several locations in Samegrelo and Abkhazia are covered by temperate rain forests. Between 600–1,000 meters (1,969–3,281 ft) above sea level, the deciduous 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 (4,921–5,906 ft), the forest becomes largely coniferous. The tree line generally ends at around 1,800 meters (5,906 ft) and the alpine zone takes over, which in most areas, extends up to an elevation of 3,000 meters (9,843 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, because of 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 deciduous species include several varieties of maple, aspen, ash, and hazelnut. The Upper Alazani River Valley contains yew forests.
At higher elevations above 1,000 meters (3,281 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 meters (1,640–6,562 ft) above sea level, with the alpine zone extending from 2,000–2,300 meters/6,562–7,546 feet to 3,000–3,500 meters/9,843–11,483 feet. 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-meter (11,483 ft) line in most areas of eastern Georgia.
