The article clarifies the morphology, variability, species composition and ecology of the ash genus of theRussian Far East in connection with the prospects for their protection and economic use. Hybridization of ash trees hasbeen proven. In the Far East, 5 species of ash are known: Fraxinus mandshurica Rupr., F. rhynchhophylla Hance,F. densataNakai, F. stenopterus Urussov and F. sieboldiana Blume var. serrata Nakai. To study the variability of species, a gene-ecological decoding of specific characters was used, which makes it possible to clarify taxonomy and biology. The article describes the critical signs of ash trees, indicates the places of their growth.
