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. The general landscape of eastern Georgia comprises numerous valleys and gorges that are separated by mountains. In contrast with western Georgia, nearly 85 per cent 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.
