| Summary: | The results of the introduction of species from harsh areas of the West Siberian, Altai-Sayan, Middle, North-East Siberian and Okhotsk-Kamchatka provinces in the botanical garden of BSTU, which is located in the Republic of Belarus in the East European province. The woodland is part of Nemansko-Prіdneprovsky geobotanical district subzones hornbeam-oak-conifer forests. The climate is moderately cold and moist. The period with positive air temperature is 240 days. The amount of rain in a year on average is 650 mm. Over 60 years of botanical garden planted 59 species of flora of Siberia. Significant replenishment of the collection was carried out in 1961, 1977, 1981. Currently, 40 species survived. The rest for vari-ous reasons, dropped out of the collection. Well settled down and go through the whole cycle of species such as Picea obovata, Abies sibirica, Pinus sibirica, Berberis sibirica, Spirea humilis , Caragana microphylla, Sorbus sibirica, Betula platyphylla, Caragana aurantiaca and others. Not tested species such as Sibireal altainsis, Prunus sibirica, Alnus hirsuta, Populus laurifolia, Lonicera altaica, Betula fusca, Betula dahurica, Betula kirghisorum, Amygdalus ledebouriana and others. In the extremely depressed state on the verge of dropping out of the collection are Larix gmelinii, Larix sibirica, Quercus mo ngolica, Malus floribunda and others. The main reasons for reducing the total number of species and number of plants in groups are over-planting density, depressing light-loving species of flora, shade under the canopy of trees, etc.
