[email protected] Abstract: The detailed research of bryophyte flora, carried out in 2008-2011 on fortifications from the times of the First World War and Second World War in Grodno district, resulted in recording 101 species, of which 95 species were true mosses (Bryophyta) and 6 species were hepatics (Marchantiophyta). Because the substratum displayed certain ecological similarity with carbonate rocks, we made comparative analysis of the species list. The total of 28 rare and very rare (in Belarus scale) bryophyte species were recorded, of which 3 species were included in the Red Data Book of Belarus; 3 species had a conser- vation status at the European level. Key words: bryophyte flora, concrete fortifications, carbonate rocks, comparative analysis 1. Introduction These constructions occur more often in the western part of the country. Older fortifications, built before the First In general, within a region, bryophyte floras retain World War (WWI), were the most interesting to us, in more ancient features than vascular floras. At the same particular the forts encircling Grodno town which are time, the mobility of bryophytes should not be under- especially extensive.
