The distribution and coenotical differentiation of F. heterophylla in the flora of Ukraine were investigated. Significant decrease of amount of species localities for the last 100 years was detected as a result of the direct extension of settlements, and also changes of ecological conditions where species grows determined by transformation of forest communities structure. The complete actual localities enumeration of species compared with the herbarium data has decreased.
