The history of the formation of the population structure of Juniperus communis L. (Cupressaceae) in the Cis-Urals and the Southern Urals

The possible ways of the historical development of juniper ( Juniperus communis L.) in the Cis-Urals and in the South Urals are considered. The main habitats and populations of the species are indicated. It is shown that the history of the settlement of Juniperus communis is consistent with the history of the development of pine forests in the region. The South Ural mountain population has the earliest origin (over 12 thousand years), the Cis-Ural forest-steppe population has the most recent (about 3-4 thousand years), the Cis-Ural forest population has an average formation time (about 10-12 thousand years).
