On the example of ca. 40 vascular plant species and subspecies of the Wrangel Island flora the idea of phytogeographical markers is illustrated. Such markers can be represented by individual plant taxa, their complexes or communities which are attached to the distinct territory and contain certain biological, ecological and historical information.
The reviewed taxa can be assigned to three marker groups: 1) of cryoarid climate periods, 2) of thermic maximums periods, 3) of maximal mountain-valley glaciations periods. The possibility of use of marker taxa for plant cover of dried
arctic shelf reconstruction is shown.
