South Siberian-Pontic-Pannonian flora region

The South Siberian-Pontic-Pannonian flora region is a flora region - a unit of the floristic structure - in Central and Eastern Europe and Asia , which extends from southern Siberia via the Ukraine , Transylvania , Vojvodina and the Hungarian lowlands to the eastern edge of the Alps in Austria . It is itself a part of the Holarctic . The vegetation is strongly influenced by the continental climate with low rainfall, high summer and low winter temperatures. The area would be naturally forested up to about 50 kilometers east of Bucharest, but secondary steppes were created due to the centuries of grazing by human livestock. The climatically conditioned primary steppes begin to the east of it.

The region consists of three provinces:

• The Pannonian Floral Province in the west includes the Hungarian Plain and adjacent areas of Hungary , Serbia , Romania , Slovakia , Moravia and Austria .
• The Pontic Floral Province , located north of the Black Sea , adjoins it in the east and extends to the southern foot of the Urals .
• The South Siberian Floral Province is located even further east and ends at the western foot of the Altai Mountains in Kazakhstan .

Typical South Siberian-Pontic-Pannonian floral elements are the spring adonis and the Siberian bellflower .
