Abstract
This article describes the identification results of Important Plant Areas within the Peri-Tien Shan botanic-geographic sub-province. It was shown that identification of Important Plant Areas for Kazakhstan territory is the crucial tool for conservation of botanic diversity as well as rare, endemic and relic species. The results of the survey and their compliance with the criteria were shown by the example of three among 32 detected important areas. The botanic value of areas and their phytocoenotic diversity were demonstrated. The rare, endemic and relic species of each area were recorded.
