“…From the entrance to the central part of the largest grotto of the cave, there is a blanket of perennial ice. In the center of the grotto is a clay scree, frozen in some places, in the marginal part of the glacier clay, covers the ice with a layer up to 0.5 m (Kadebskaya and Stepanov 2016). Kutuk-2 cave (Stalactite cave) is located 2.5 kilometers north of the Kutuk-Sumgan cave.…”

“…This gallery is overlapped by a siphon at a depth of 110 m and has a narrow passage to the main part of the cave (Golubev et al 1976). In winter seasonal glaciation forms in the entrance zone of the cave (Kadebskaya and Stepanov 2016).…”

“…At a depth of 100-110 m from the entrance side tributaries flow into the main gallery. The cave is watered; the stream is fed by the glacier of the near-entrance part and by infiltration water 2 (Bogdanovich 1969; Kadebskaya and Stepanov 2016).…”

This article presents results of a study of bryophytes in seven caves of the Kutuk tract of the National Park «Bashkiria» of the Republic of Bashkortostan, including the largest cave in Bashkiria – Kutuk-Sumgan.Fifty-five bryophytes species were found in the studied caves. The dominant species in all caves was Timmia bavarica. The species composition of bryophytes of each cave is unique. Among identified bryophytes species 23, species were found only in one cave, and 11 species in 2 caves. During our survey, we found 31 species in Kutuk-Sumgan Cave, 21 species in Kutuk-2 and Kutuk-3 caves, 19 species in Kutuk-4 caves, 18 species in Vintovaya and Zigzag caves and 14 species in Kutuk-1 cave. Using the Jaccard and Phi-squared similarity indices, we revealed the stability of the bryoflora of the caves in different years and show its changes. Changes in the composition and structure of mosses in the Kutuk tract may be caused by mechanical influences. Benchmark similarity analysis allowed us to determine the influence of entrance morphology and glaciation in the photic zone of the caves on the composition of bryophytes.Using the Kutuk tract caves as an example, it is shown that in the primary analysis of the bryoflora, when selecting a characteristic cave, up to 40% of the total species composition of the caves can be identified in a single cave. The current study of Kutuk tract caves shows that identification of the primere analyses of bioflora permits identification of up to 40% of species composition of an individual cave.Three criteria for selecting a characteristic cave were identified: size of the photic zone and morphology of the entrance, diversity of habitats, and the least degree of disturbance.
