The article presents a list of bryophytes on the territory of the forest park “Pohu­lyanka” in Lviv city which includes 143 species of mosses which belong to 79 gene­ra, 36 families of two divisions: Marchantiophyta and Bryophyta. Changes in the species composition for the last 50–100 years were analyzed: 34 species were not detected, the reduction of the species diversity of the liverworts and decreasing of the proportion of moss families: Polytrichaceae Schwägr., Thuidiaceae Schimp., Hylocomiaceae M. Fleisch. are noted. These families are changed the least: Brachytheciaceae Schimp., Hypnaceae Schimp., Mniaceae Schwägr. 72 species of bryophytes are indicated for the studied area for the first time, and Eucladium verticillatum (With.) Bruch et Schimp. is indicated for the first time for the territory of Lviv region. 25 species are rare for the nemoral and forest-steppe zones. The substrate affiliation of the bryophytes was presented. It was shown that the spectrum of substrates for the epiphytes has expanded as a result of the anthropogenic activity.
