Forests cover about 39.9 per cent of the territory of Georgia and contain the largest part of Georgia’s species diversity. Habitats such as semi-deserts, steppes, wetlands, flood plain forests and Colchic forests are endangered. Broadleaf forests consist primarily of oriental beech (Fagus orientalis), Georgian oak (Quercus iberica), hornbeam (Carpinus caucasica, C. betulus) and chestnut (Castanea sativa).
