Effect of tree species identity and related habitat parameters on understorey bryophytes – interrelationships between bryophyte, soil and tree factors in a 50-year-old experimental forest

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