We present a first overview of the bryophyte
flora of the Russian part of the Curonian Spit as part of the Kaliningrad
Province, Baltic Sea region. Based on more than ten years of field
investigation, herbarium revisions and literature studies, a total of 223 taxa
of bryophytes are recorded, of which 203 species, one subspecies and three
varieties were found within the past 30 years and 15 species are known only
from old literature quotations. Bryum elegans, B. klinggraeffii, Dicranum
tauricum, Ephemerum minutissimum, Rhynchostegium megapolitanum
and Schistidium crassipilum are recorded as new for the territory of the
Kaliningrad Province. We give comments on main habitats and distribution of all
species and additional notes on invasive and rare species.
