Results of primary introductory test of 21 species of woody and shrubby plants of natural flora of the Western Kazakhstan in the conditions of Mangyshlak experimentalbotanical garden are given in article. Selection of introduced species was made from natural habitats of the Mangystau, Atyrau, Aktyubinsk and West Kazakhstan regions. Examining taxa enter into the following ecological groups: xerophytes (5 species), mesophytes (7 species), mesoxerophytes (5 species) and xeromesophytes (4 species). Primary test in culture allowed allo-cating 3 groups of plants: very steady — 9 taxa; steady — 11 taxa; not steady — 1 taxon. The analysis of economic and useful properties allowed defining that 15 species are suitable as ornamental plants, 10 — as food, 8 — phytomeliorative, 11 — melliferous, 6 — medicinal, 2 — as a stock for reproduction of cultivars. The correlation between ecological group of a taxon and resistance to local climate is not revealed. Species for further introductory test are defined.
