The assessmentof the introduction resistance of the garden arboretum gene pool was given based on complex indicators of plant viability according to the data of long-term experimental research. To determine the indicators of viability, adaptation, the method of phenological observations in botanical gardens was applied. The prospect of taxa for use in the landscaping of the region was determined according to the integrated scales of M.P. Kosarev, P.I. Lapina, S.V. Aristova. Accordingto the complex of biological and economic characteristics, 370 species, forms, varieties of coniferous and angiosperms are recommended for use in landscaping of region. Materials for monitoring the introduction resources of the arboretum of the Altai Botanical Garden
