The article presents 80 relevés of bryophyte communities on living trees and dead wood sampled within Holosiivskyi National Nature Park (Kyiv, Ukraine). They are referred to 16 associations of 5 classes (Frullanio dilatatae-Leucodontetea sciuroidis, Cladonio digitatae-Lepidozietea reptantis, Neckeretea complanatae, Hylocomietea splendentis, Platyhypnidio-Fontinalietea antipyreticae). Most frequent are communities dominated by Hypnum cupressiforme and H. pallescens of the class Frullanio dilatatae-Leucodontetea sciuroidis (on bark of living trees) and Brachythecium rutabulum of the class Cladonio digitatae-Lepidozietea reptantis (on dead wood). In mesic forests, trees are usually not inhabited by bryophyte communities. Much more often, they occur in wet forests, near water, and in mesic forests in ravines. Four associations are reported in Ukraine for the first time: Callicladietum haldaniani LeBlanc 1963, Brachythecio rutabuli-Plagiomnietum cuspidati (Felföldy 1941) Plamada 1982, Brachythecio rivularis-Hygrohypnetum luridi Philippi 1965, and Leptodictyo riparii-Hygroamblystegietum varii Hugonnot et Celle 2013.
