The results of similarity analysis of partial rare dendrofloras of protected parks of the Steppe of Ukraine in the context of administrative areas, certain objects and corresponding categories of Nature-Reserve Fund are shown in the article. Overall, the top ten local rare dendrofloras ex situ of protected parks are heterogeneous and correlated in a low level. The most similar by species composition of plants are Donetsk Botanical Garden of NAS of Ukraine and arboretum of Biosphere Preserve “Askania-Nova” (K_sc=0,69). The closest correlation is between regional rare dendrofloras of Odessa, Donetsk, Kherson and Dnipropetrovsk regions. Botanical gardens and arboretums (K_sc=0,72) are the most similar among the studied categories of NatureReserve Fund by the species compositions of rare introduced arboreal plants.
