Summary: In the sharply continental climate of the Orenburg region with low snowy winters, regular thaws, as well as late spring frosts with characteristic return colds and dry summers it is very difficult to ensure rooting of woody plants. Factors such as root system volume, tree height and trunk girth have a major influence on species introduction. It is difficult for plantations with a trunk girth of less than 20 cm and an underdeveloped root system to withstand strong steppe winds without breaking. The purpose of the study was to assess the viability of large woody plants of non-domestic species and the possibility of their further use in landscaping practice in Orenburg. Thanks to the method of determining the ratio between the parameters of the ball of soil and tree size proposed by G. W. Watson, as well as A. T. Leiser, C. E. Whitcomb, the optimal sizes of seedlings were selected. Based on the methodology of V. F. Abaimov and A. I. Kolesnikov, we competently planted large-sized plants in the open ground. The assessment of seedlings perspectiveness was performed according to the scale of P. I. Lapin and V. F. Abaimov. As a result of long-term studies of planted foreign species adaptation we found that 99% species of 2.5—5.5 m high safely took root despite the harsh climatic conditions of the Orenburg region. Of these, 23 % suffered slightly from negative environmental impact and 1 % died. Based on our observations, out of 76 foreign species, 75 of them scored from 92 to 97 points on the prospectivity scale and were classified as quite promising. For the first time such large plants imported from the Moscow region were used in the city landscaping of Orenburg. Such species as black walnut (Juglans nigra L.) and Manchurian walnut (Juglans mandshurica Maxim) have not been used in urban landscaping before. All species have proved to be promising and are recommended for landscaping of Orenburg.
