Biodiversity in Georgia

The Caucasus as a Global Biodiversity Hotspot

With 62 out of 100 points on the global biodiversity index, Georgia ranks in the upper midfield — remarkable for a country the size of West Virginia. Georgia lies at the heart of the Caucasus — one of 36 global biodiversity hotspots as classified by Conservation International (CI). The hotspot concept identifies regions with at least 1,500 endemic plant species that have simultaneously lost over 70% of their original habitat. The Caucasus clearly meets both criteria: over 1,600 endemic vascular plants grow in the region, and large-scale deforestation and agricultural expansion have reduced primary forest to an estimated 20–25% of its original extent. For a country of 69,700 km², the biological diversity is remarkable. For comparison: the United Kingdom with nearly four times the area records approximately 1,500 native plant species, while Georgia hosts over 4,500.

Flora — Colchic Forests and Endemism

Georgia's plant kingdom encompasses over 4,500 vascular plant species, of which approximately 900 are endemics — species found nowhere else on Earth. The Colchic forests in western Georgia (Imereti, Guria, Samegrelo, Adjara regions) are considered relics of the Tertiary deciduous forest that millions of years ago covered wide swathes of Eurasia. Here, species survived the Ice Ages thanks to the mild, humid climate along the Black Sea. Characteristic species include the Colchic Boxwood (Buxus colchica), the Pontic Oak (Quercus pontica), the Medvedev Birch (Betula medwediewii), and the Colchic Holly (Ilex colchica). The Batumi Botanical Garden, founded in 1912, houses over 5,000 plant species and serves as the country's most important ex-situ conservation program. In eastern Georgia, by contrast, dry steppe and semi-desert landscapes dominate with Artemisia species and xerophytic shrubs — a contrast as stark as between California's coast and Nevada's interior.

Fauna — From High-Mountain Hunters to Lowland Dwellers

Georgia's wildlife encompasses approximately 100 mammal species. The most iconic:

Caucasian Tur (Capra caucasica): Two subspecies — the Western Caucasian Tur (C. c. severtzovi) in Svaneti and the Eastern Caucasian Tur (C. c. cylindricornis) in Tusheti — inhabit steep rock faces above 2,500 meters. The population is classified as "Near Threatened" by the IUCN. The Georgian APA estimates the population at 3,000–5,000 individuals.

Persian Leopard (Panthera pardus tulliana): A small, fragmented population survives in southern Georgia, particularly in Vashlovani National Park and the adjacent border area with Azerbaijan. Camera traps operated by the Nacres Foundation (Centre for Biodiversity Conservation & Research) documented multiple individual sightings between 2018 and 2024. The population is estimated at fewer than 10 animals in Georgia.

Bearded Vulture (Gypaetus barbatus): The largest raptor in the Caucasus, with a wingspan of up to 2.8 meters, breeds in Svaneti and Tusheti. In the European Alps, the Bearded Vulture was saved through a reintroduction program — in the Caucasus, it survived without human intervention.

Caucasian Viper (Vipera kaznakovi): Endemic to the western Caucasus, this colorful venomous snake inhabits moist forests in Adjara and Guria. It is listed as "Endangered" by the IUCN.

The avifauna comprises over 380 documented species. The Kolkheti wetlands near Poti constitute a significant staging area on the East Atlantic Flyway — in autumn, tens of thousands of migratory birds rest here, including the Dalmatian Pelican (Pelecanus crispus), globally classified as "Near Threatened."

Regional Differentiation of Biodiversity

Biological diversity varies dramatically between regions. Western Georgia (Colchic Lowland, Adjara) with 2,500–3,500 mm of annual precipitation is the most species-rich area — subtropical forests, wetlands, and montane ecosystems overlap. Eastern Georgia (Kakheti, Kartli) receives only 400–600 mm of precipitation and harbors a drought-adapted, less diverse fauna and flora. The high-mountain regions of the Greater Caucasus (Svaneti, Khevsureti, Tusheti) feature a specialized alpine flora with numerous endemics — including over 150 plant species found only above 3,000 meters.

Threats and Conservation Measures

The most severe threats to Georgia's biodiversity are illegal logging (estimated at 400,000–600,000 cubic meters annually according to the Caucasus Environmental NGO Network, CENN), poaching, overgrazing, and uncontrolled urbanization — particularly in the coastal zone near Batumi and the urban belt around Tbilisi. The National Biodiversity Strategy and Action Plan (NBSAP), last updated in 2014, sets targets for expanding protected areas and combating invasive species. Implementation is supported by Ilia State University and international partners including the WWF Caucasus Programme. The GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit) has funded sustainable forestry projects in Adjara and Guria since 2018.

Practical Tips for Nature Enthusiasts

For biodiversity observation, Lagodekhi National Park (birds, mammals), the Kolkheti wetlands (migratory birds, September–November), and Mtirala National Park (Colchic flora) are the top recommendations. Guided tours are organized by the Georgian Biodiversity Database (biodiversity-georgia.net) in collaboration with local rangers. Those experienced with observing alpine ecosystems in the Rockies or the Scottish Highlands will find comparable habitats in the Caucasus — but with a higher endemism rate and far fewer visitors. The iNaturalist app now records over 45,000 observations from Georgia and is the best tool for species identification in the field.
