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 gene ra, 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 foreststeppe 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.

The paper elucidates results of bryoflora study in the nature reserve «Medobory». In general 132 species of 28 families and 71 genera are found. The list includes 4 species of liverworts and 128 species of mosses, information about species distribution, life forms and also taxonomic comments for selected species.

Bryophytes as indicators of recovery posttechnogenic landscapes of sulfur extraction.

49 bryophytes species belonging to 2 divisions, 3 classes, 8 orders, 17 families, 32 genera have been found on the territory of sulphur mining dump. Taxonomic, ecological and biomorphological structure of bryophytes have been analyzed, their life strategies have been determined. Seasonal changes in the projective cover and biomass of dominant mosses species have been investigated. The obtained data testify the important role of bryophytes in restoring vegetation cover on the devastated territories of sulphur extraction.
