Since the work of Verseghy (1970s), their productivity has hardly been analyzed in Hungary. We studied dynamics of cryptogams at two East-Hungarian dry sandy grassland sites. The sites of Corynephorus canescens and of Festuca vaginata dominance, respectively, belonging to the community Festuco vaginatae-Corynephoretum have been monitored. We aimed at 1) quantifying the floristic composition, diversity and biomass of terricolous cryptogamic communities; 2) exploring the response of cryptogams to management changes (subject to different grazing pressure); 3) studying the effect of an experimental change (fencing) of management on the cryptogamic assemblages also with regard to the performance of the legally protected lichen, Cladonia magyarica. Cryptogamic vegetation has been compared in both sites in 2013 and 2018, respectively, at an experimentally fenced part as well as a non-fenced part subject to changing grazing pressures, respectively. Forty microplots per site per management have been analyzed in both years. Samples of lichens and bryophytes were hand-sorted, dried then measured. Spot tests and HPTLC have also been applied in identification of lichen taxa in addition to morphological studies. Fencing has led to increased biomass of cryptogams within a few years. Lichens in general benefited comparatively more from exclosure than did bryophytes. Increase of lichen biomass (especially that of Cladonia rangiformis) was clearly due to the over 10-year absence of grazing. The only lichen favoured by moderate grazing was the legally protected C. magyarica. Short spells of low intensity grazing can promote species richness of cryptogams in the community.
