Abstract

It is characterized the condition and results of studying the bryophytes of nature reserves the Forest-Steppe of Ukraine: «Mikhaylivska tsilyna» (Sumy region), «Kanivsky» (Cherkasy region) and «Medobory» (Ternopil region). For each of the natural protected objects the literature sources, herbarium materials of number of Ukrainian herbarium and original data were analyzed. The species composition of bryoflora of each natural reserve, the main range of families and a list of interesting and rare species were established. The bryophytes flora of natural reserve «Mikhaylivska tsilyna» includes 58 species, which belong to two divisions, 21 families, 39 genera. Division Marchantiophyta represented by five species of four genera, four families, Bryophyta – 53 species, 35 genera, 17 families. The flora of mosses is typical for steppe zone of Ukraine and represents its zonal type of vegetation – meadow steppes. The flora of mosses of natural reserve «Kanivsky» contains 133 species of three divisions, 45 families, 75 genera. There are two species of Anthocerotophyta, 29 species of Marchantiophyta and 102 ones of Bryophyta among them. The advantage of nemoral forest species reflects the specific features of zonal type of vegetation of the Forest-Steppe of Ukraine – deciduous forests, including hornbeam oak forests. The bryoflora of the natural reserve «Medobory» is the most rich: it includes 144 species of mosses – 8 species of Marchantiophyta, 136 ones of Bryophyta, that belong to the two divisions, 35 families, 79 genera. It primarily represents the regional characteristics of the reserve, as is rich in species confined to limestone. So the bryoflora of listed reserves represents the zonal types of vegetation of Forest-Steppe of Ukraine and its regional specificity in part. The research of moss vegetation and its classification is now necessary.
