“…For this reason, we assume that biocrust growth in our study area was limited by leaf litter fall rather than suppression by vascular plants. A negative effect of leaf litter was also reported in several other studies (Wu et al, 2020;Alatalo et al, 2020;Márialigeti et al, 2009;Fojcik et al, 2019;Mercier et al, 2019).…”

“…For example, Rola et al (2021) showed that soils with a more acidic pH promoted a larger bryophyte coverage, which 285 could explain, among other things, the generally higher bryophyte cover in CT in our study. even with high total vegetation cover, which contradicts observations that vascular plants limit biocrust growth in different ecosystems (Corbin and Thiet, 2020;Bergamini et al, 2001;Fojcik et al, 2019). Ingerpuu et al (2005) verified in a grassland experiment that vascular plants could actually facilitate moss growth, explaining this by the fact that vascular plants create a more favourable microclimate under their canopy.…”

Abstract. Soil erosion continues to be one of the most serious environmental problems of our time, which is exacerbated by progressive climate change. Until now, forests have been considered an ideal erosion control in this regard. However, even minor disturbances of the forest floor for example from heavy vehicle used for timber harvesting can cause substantial sediment transport. An important countermeasure is the quick restoration of the uncovered soil surface by vegetation. In this context, biological soil crusts (biocrusts) can play a vital role, as they are known for their soil-protective effect. This study examined the natural succession of pioneer vegetation in skid trails on four soil substrates in a central European temperate forest and investigated their influence on surface runoff and sediment discharge. We applied rainfall simulation experiments on small-scale runoff plots and continuously surveyed vegetation during the same period, primarily to map biocrust development. Skid trails on clayey substrates showed considerably higher biocrust cover and species richness. Biocrust cover was higher in center tracks than in wheel tracks, while there was no clear difference for biocrust species richness with regard to track position. Although biocrusts were quickly overtopped by vascular plants, they managed to coexist until their growth was restricted due to leaf litter fall. Brachythecium rutabulum and Oxyrrhynchium hians were the most important and persistent pioneer biocrust species, while Dicranella schreberiana and Pohlia lutescens were volatile and quickly disappeared after spreading in summer. Soil erosion was reduced with pioneer biocrust vegetation in summer, and again increased in winter. Total amount of sediment discharge was clearly site-dependent, indicating a high relevance of underlying substrates. Sediment discharge was 13.2 times higher in wheel tracks compared to undisturbed forest soil, and bare soil runoff plots produced 22-fold sediment discharge compared to undisturbed forest soil. Overall, bryophyte-dominated biocrusts contributed more to mitigating soil erosion than vascular plants. When soil coverage exceeded 50 %, biocrusts resulted in an average of 18 times less sediment loss compared to vascular plants.

“…However, most studies concerned grassland communities in which the herbaceous plant layer is, as a rule, significantly more developed than in the temperate forests. As regards forests, Fojcik et al (2019) also revealed the negative impact of herbaceous plants on the total coverage of bryophytes in a managed temperate mixed forest in Poland. Similarly, Turkington et al (1998) showed that the addition of NPK fertilizer to a nutrient-poor boreal forest ecosystem resulted in an intensive growth of vascular plants, mainly grasses, which at the same time caused a decrease in bryophyte cover.…”

Aim Overstorey tree species influence both soil properties and microclimate conditions in the forest floor, which in turn can induce changes in ground bryophyte communities. The aim of the study was to investigate the effect of tree species identity and the most important habitat factors influencing understorey bryophytes. Methods We assessed the effect of 14 tree species and related habitat parameters, including soil parameters, vascular plant presence and light intensity on bryophytes in monospecific plots covered by nearly fifty-year-old trees in the Siemianice Experimental Forest (Poland). Results The canopy tree species determined bryophyte species richness and cover. The strongest differences were observed between plots with deciduous and coniferous trees. Soils with a more acidic pH and lower content of macronutrients supported larger bryophyte coverage. We also found a positive correlations between vascular plants and availability of light as well as bryophyte species richness. Conclusion Tree species identity and differences in habitat conditions in the forest floor lead to changes of ground bryophyte richness, cover and species composition. Consequently, the changes in the dominant tree species in the stand may result in significant repercussions on ground bryophyte communities. We indicated that the introduction of alien tree species, i.e. Quercus rubra, has an adverse effect on bryophyte communities and suggested that the selection of tree species that contribute to the community consistent with the potential natural vegetation is highly beneficial for maintaining ground bryophyte biodiversity.

“…Ignatov & Huttunen), which results in a greater diversity of bryoflora (Mazimpaka & Lara 1995;Mežaka & Znotiņa, 2006;Márialigeti et al, 2009). Lophocolea heterophylla was found most often on the pine trunk bases; Pundiak & Grodzki (2017) and Fojcik et al (2019) also mention such a preference of this liverwort on epiphytic habitats. The occurrence of bryophytes on the trunk bases is also an advantage due to the higher humidity compared to the higher parts of a tree (Mazimpaka & Lara 1995;Pundiak & Grodzki, 2017), as well as a higher degree of bark cracking (Ranius et al, 2008).…”

The vertical distribution of epiphytic bryophytes in European forests are still relatively poorly understood. The aim of the study was to analyse the diversity and vertical zonation of epiphytic mosses and liverworts on selected tree types (Quercus petraea, Betula pendula and Pinus sylvestris) within windthrow areas in the Kampinoski National Park (Central Poland). The investigations were performed in five parts of the trees: the tree base, lower trunk, upper trunk, lower crown, and upper crown. Deciduous trees have more species than pine trees (13 on Quercus and Betula, 8 on Pinus). The type of phorophyte was crucial for the differences in the species composition from the tree base to the upper crown that was observed. The highest richness of bryophytes was recorded on the tree bases, while the lowest was recorded in the upper parts of the crowns. The variability of the habitat conditions in the vertical gradient on the trunk that affected the patterns of the occurrence of species with different ecological preferences was determined using the Ellenberg indicator values. An increase in the value of the light and acidity indicators from the base of the trunk upwards and decreasing tendency in the case of moisture indicator was noted.
