Abstract

type:text

Cool temperate semi-arid vegetation landscape around the Arkaim eco-preserve was introduced and the phytogeographicaldifferences between forest steppe in and around the Arkaim, south-eastern Ural, and semi-arid subtropicalsavanna in south-western Africa were discussed. We considered forests of Betula pendula and Pinus sylvestris,instead of some types of steppe, as potential natural vegetation in and around the Arkaim, because ofrelatively sufficient water supply to the vegetation. Both the Betula forest and Pinus forest will be climax vegetationin a cool temperate semi-arid zone characterized by the severe condition as arid and/or low temperature. Peoplewho occupied around the Arkaim in the Bronze Age are assumed to have used forests and changed them intosteppe. Forest area in south-eastern Ural is usually bounded clearly by the area of grass steppe. Contrarily semi-aridsubtropical woody vegetation, savanna, is represented by open woodland with sparse distribution of trees. Forestvegetation accompanying with water deficiency in sub-tropical zone shows open and sparse forest type becauseroot competition among individual roots from insufficiency of soil water should reduce density of stands.
