Species richness, composition and abundance of the bryophyte diaspore bank of Central
temperate mixed forests were compared with the forest-floor bryophyte assemblage.
The impact of
environmental variables and anthropogenic disturbances, including tree species composition,
structure, microclimate, light conditions, soil and litter properties, management
history, and landscape
properties, potentially influencing bryophyte diaspore bank assemblages were explored.
70–100 years old mixed stands with differing tree species composition were examined
in the O˝ rség
National Park, Western Hungary. The diaspore bank was studied by soil collection and
data were analysed by multivariate methods. Contrary to the forest-floor bryophyte
substrate availability, tree species composition and stand structure were the most
variables, the composition and abundance of the diaspore bank was mainly affected
by site conditions
(microclimate, litter and soil properties). Species richness of the bryophyte diaspore
bank was lower than
that of the forest-floor bryophyte assemblage. Short-lived mosses (colonists, short-lived
dominant in the diaspore bank, as opposed to the forest-floor bryophyte community,
mosses dominated. In the studied forests, the importance of the bryophyte diaspore
bank was relatively
low in the regeneration and maintenance of the forest-floor bryophyte vegetation.
