The book describes richness and diversity of Georgia's vegetation.
Contrasting ecosystems coexist on the relatively small territory of the
country and include semi-deserts in East Georgia, Colchic forests with
almost sub-tropical climate in West Georgia and subnival plant
communities in high mountains. West Georgia lacks xerophilous vegetation
zone and mesophilous forest vegetation spreads from the sea level to
subalpine zone. The Colchic refugium (West Georgia) ensured survival of
the Tertiary's mesophilous forest flora. Vertical profile of the
vegetation is more complex in East Georgia with semi-desert, steppe and
arid open forest zone. In South Georgia the montane zone represented by
montane steppe is devoid of forests
