The geomorphology of the Georgian coast is influenced by the many rivers that rise or flow through the region. This biome occurs at between 150 and 600 m. The vegetation is characterized by halophytic and ephemeral species. One form of eroded deserts is found on Iori Plateau, where the rare endemic Tulipa eichleri can be found. The climate is subtropical with continental dry winters and hot summers. Snow is rare and snow cover is unstable. The bearded grass (Botriochloa ischaemum) ecosystems are the most spread on the steppe.
