Stable bryophyte communities on rock dumps of the Chervonograd mining area were investigated; their rank as epigeic briosynusiae was specified. Structure and composition of the moss cover of the region were analysed. Floristic composition, projective coverage and life forms of bryophytes, features of ecological and coenotic differentiation of the bryoflora were defined. It was established that in biomorphic structure of mosses, species with growth forms of turfs and mats predominate, while among ecomorphs, dominating are heliophytes, mezophytes and xeromezophytes as well as epigeic ones. Results of geographic analysis indicate that the studied bryoflora is boreal (13 species, 65%). A noticeable proportion of boreal moss species and wide distribution of cosmopolitans, compared to zonal vegetation, resulted from the high level of anthropogenic transformation of the coal mining area.

Keywords: rock dumps, bryosynusiae, biomorphes, ecological structure, geographical elements
