“…The species densities were also similar to other comparable studies. Vanderpoorten et al (2004) found, on average, seven species m -2 in a mown calcareous grassland in Belgium, and Peintinger and Bergamini (2006) found seven species 0.04 m -2 from mown fen meadows in Switzerland. Ingerpuu et al (1998) found 4-10 species m -2 in a wooded pasture in Estonia.…”

“…These include both the creation of patches of bare mineral soil and the reduction of living and dead vascular plant biomass (van Tooren et al 1990;Aude and Ejrnaes 2005;Peintinger and Bergamini 2006;Mayer et al 2009;Preston et al 2009). Mowing has often proved to be less favourable for bryophytes, indicating the importance of local soil disturbances by the grazing animals (van Tooren et al 1990;Bergamini et al 2001;Vanderpoorten et al 2004).…”

Can re-establishment of cattle grazing restore bryophyte diversity in abandoned mesic semi-natural grasslands?

Changes of agricultural practices have led to decline of semi-natural habitats sustained by traditional animal husbandry in many European regions. The abandonment of semi-natural pastures leads to increase of vascular plant biomass and subsequent decline of weak competitors such as bryophytes. Re-establishing traditional animal husbandry may potentially restore biodiversity but the success of such measures remains insufficiently known. In this study, we asked if re-establishing cattle grazing on previously abandoned grasslands will restore their bryophyte communities. The effect of cattle grazing on bryophyte communities of mesic semi-natural grasslands was studied in south-western Finland in a comparison of (i) continuously grazed pastures, (ii) previously abandoned pastures where grazing was re-established during 1990s, and (iii) abandoned pastures, where grazing had ceased during late 1960s to early 1980s. The average cover, species richness, species density and species diversity of bryophytes were significantly higher in the continuously grazed than in the abandoned grasslands. Ordination analyses revealed clear differences also in community structure between the management classes. Re-established grasslands were ecologically heterogeneous and situated in between the continuously grazed and abandoned grasslands in all characteristics, indicating variable effect of the restoration measure. Seventeen bryophyte species were recognized as significant indicators of the three grassland classes, four of which could be used as indicators of valuable grassland habitats. Although there was variation in the consequences of re-introduction of grazing, the results give evidence of positive effect of grazing on regaining bryophyte diversity of abandoned grasslands.

“…Das Vorkommen akrokarper Moose auf diesen Flächen ist auf die durch Feldmäuse geschaffenen Erdblçssen zurückzuführen, die hier häufiger als bei den anderen Bewirtschaftungsmassnahmen auftreten und für welche Gigon und Leutert (2003) einen positiven Einfluss auf die Artenvielfalt an Blütenpflanzen nachweisen konnten. Vanderpoorten et al (2004) hoben ebenfalls den Wert solcher Freistellen für akrokarpe Moose hervor. Das vermehrte Auftreten dieser Sonderstandorte führte wohl zu den etwas hçheren Moosartenzahlen als auf den anderen Flächen.…”

“…In der vorliegenden Untersuchung wurde gezeigt, dass sich das von 1977 bis 1999 durchgeführte Brennen sehr negativ auf Artenzahl und Deckungsgrad auswirkte und dass dieser negative Einfluss durch Umstellung des Managements auf jährliche Herbstmahd noch nicht aufgehoben werden konnte. Ehemalige Brache führte zwar ähnlich wie beiVanderpoorten et al (2004) nicht zu einer dauerhaften Verminderung der Moos-und Flechtenartenzahl, aber zu einer deutlichen Abnahme der kalkmagerrasentypischen Moos-und Flechtenarten (Tab. 2).…”

Helv. 118: 95 -109.Long-term effects of grassland management on the species richness of vascular plants, mosses and lichens were studied in a calcareous grassland near Schaffhausen (Switzerland). Experimental plots were treated for 22 years (1977 -1999) with different mowing regimes, annual burning in late winter, or abandonment. From 2000 onwards, all plots were mown annually in autumn. Five years later (2004), we studied the aftereffects of the previous treatments by recording the cover of vascular plants, mosses and lichens in nested plots with sizes from 0.01 m 2 to 16 m 2 . Vascular plant species richness as well as the number of species characteristic for calcareous grasslands were significantly lower in formerly abandoned or burnt plots than in regularly mown plots, with larger differences on small subplots. There was no significant effect of the previous mowing time (July vs. October) or mowing frequency (annual or every two years) on vascular plants. Mosses and lichens had been eliminated by annual burning between 1977 and 1999, and only few moss species re-colonized the formerly burnt plots until 2004. The species richness of mosses did not differ between formerly abandoned and mown plots, but there were more mesophytic and fewer xerophytic species in the formerly abandoned plots. Mesophytic mosses were also more abundant in plots that used to be mown every second year than in those mown annually. Our data indicate that even after five years of similar management, i.e. annual mowing in autumn, the previous Bot.

49 bryophytes species belonging to 2 divisions, 3 classes, 8 orders, 17 families, 32 genera have been found on the territory of sulphur mining dump. Taxonomic, ecological and biomorphological structure of bryophytes have been analyzed, their life strategies have been determined. Seasonal changes in the projective cover and biomass of dominant mosses species have been investigated. The obtained data testify the important role of bryophytes in restoring vegetation cover on the devastated territories of sulphur extraction.
