Палеохорологічні дослідження рідкісних та реліктових видів рослин в Україні: сучасний стан та перспективи

The first results of paleochorological studies of rare and relict plant species based on two model taxa, Taxus baccata L. and Betula humulis Schrank, are presented. These taxa are listed in the Red Data Book of Ukraine (2009) and considered relicts. As a result of our investigation, the maps of distribution of Taxus baccata in the western region of Ukraine for the Riss-Wurm optimum phases and distribution of Betula humulis within the plain part of Ukraine in the Allerod-Holocene were developed.
