Geobotanic investigation of 200 mire massifs resulted
in finds of 49 liverwort species in 243 geobotanic descriptions made in 78
mires of the Chelyabinsk Province. Liverwort species composition, ecological
and coenotic characteristics of mires are provided. The annotated list includes
data on frequency, coenotic distribution and affiliation, presence of
structures associated with reproduction, mire water level measurements, pH. Species
diversity and taxonomic composition mire liverworts of the study area of other
studied mire territories of Russia are discussed. Liverworts are infrequent and
not abundant in South Urals mires and usually associate with mosses. Twenty
three species are recorded for the first time for the Chelyabinsk Province
including Cordaea flotoviana, Gymnocolea fascinifera, Heterogemma
laxa, Riccardia incurvata new for
Urals and Cephaloziella spinigera new for South Urals.
