“…This conclusion is further supported by the observed AIV R (unweighted only) and AIV N (both weighted and unweighted) decreases, and is consistent with the results of studies done in some other parts of the Carpathian Mountains (Šamonil, Vrška 2007;Novotný et al 2008;Durak 2010Durak , 2011Badea et al 2012). Various authors provided different explanations of this phenomenon.…”

“…In contrast with soil acidification, changes in the light conditions of Carpathian forests have seldom been reported (Šamonil, Vrška 2007;Durak 2010;Šebesta et al 2011), and the observations do not agree with each other. In the present study, an increased share of understorey species with high light Ellenberg's Indicator Values was detected, but only the change of weighted AIV L was judged to be statistically significant.…”

“…The reports from phytosociological studies carried out in the Czech (Šamonil, Vrška 2007) and Polish (Durak 2010(Durak , 2011 Carpathians mention a decrease of AIV R, indicating a trend towards the lower soil pH or calcium concentration (Diekmann 2003). An opposite direction of change was detected at Norway spruce-dominated stands in the Ukrainian part of the mountains; interestingly, the result was not consistent with the results of soil analyses (Šebesta et al 2011).…”

“…The AIV N decrease was interpreted as the consequence of silvicultural operations. Some researchers (Šamonil, Vrška 2007;Durak 2010;Šebesta et al 2011) reported changes of AIV L, but as pointed out by Diekmann (2003), the reliability of this light-related parameter is low, as its values do not correlate well with measured light intensity over short gradients.…”

ABSTRACT:To avoid ecosystem degradation, forestry planning needs to be based on current information about the state of forest environment. Phytoindication is an inexpensive tool that allows tracking the environmental change at fine spatial scales. The present study uses this approach to assess changes within abiotic conditions of forests in the area of the Moravian-Silesian Beskids Mts. (Czech Republic). Phytosociological relevés collected in 2013 at 118 permanent plots were compared with records from the 1960s and 1970s. The changes were expressed using average Ellenberg's Indicator Values and units of the Czech Forest Typological System. Persisting soil acidification was detected, and linked to industrial deposition and planting of Norway spruce beyond its natural range. Conversion towards a higher share of broadleaved species was suggested to support soil recovery.

“…Some studies show that this phenomenon of long-term cyclical changes is rather a steady trend of the gradual replacement of fir by beech (Janík et al 2014). A possible explanation of this trend may be the long-term response of forest ecosystems to past human activity, such as the medieval colonization of mountains associated with intensive local exploitation of forests by grazing and litter raking (Samonil and Vrska 2007). Understanding the historical development of mountain forest ecosystems is therefore of great importance for understanding their current state (Agnoletti and Anderson 2000).…”

Nature Conservation 22: 51-78. https://doi.org/10.3897/natureconservation.22.12902 AbstractEuropean beech-dominated forests are crucial for maintaining biodiversity in forested mountain landscapes of the European temperate zone. This paper presents the results of research and assessment of management strategy for mountain beech-dominated forests in the Jeseníky Mountains (Czech Republic). Our approach is based on combining research on historical development of the forest ecosystem, assessment of its current state, and predictions of future dynamics using a forest growth simulation model. Using such a method makes it possible to understand the current state of the mountain beech-dominated forest ecosystem and predict its future development as a response to specific management strategies. The application of this method is therefore appropriate for assessing the suitability of selected management strategies in mountain protected areas. Our results show that a non-intervention management for mountain beech forest in the next 80 years complies with the Natura 2000 requirement to maintain the existing character of the forest habitat. Thus, the current management plan for the beech-dominated forests in the Jeseníky Mountains does not require significant corrections in the context of its conservation targets (i.e. maintaining biodiversity and current character of the forest ecosystem dominated by beech). The results of this study suggest that combining the knowledge on historical development with forest growth simulation can be used as a suitable support tool to assess management strategies for forest habitats in protected areas.

Tree radial growth is influenced by individual tree abilities, climate, competition, disturbance regimes, as well as biogeomorphic processes – including biomechanical interactions between trees and soil. Trees are actively involved in hillslope dynamics, both responding to and affecting many (bio)geomorphic processes. Using dendrochronology, we studied feedbacks associated with tree–soil–landscape formation, specifically relationships between hillslope processes, biomechanical effects of trees in soils, tree microhabitat conditions and their morphological adaptations, in the flysch zone of the Carpathians. We visually evaluated stem shape, microhabitat conditions and the biomechanical effects of 1663 trees. Cores were taken in four growing directions from 224 individuals of European beech (Fagus sylvatica L.). In a set of 193 cross‐dated beeches, average tree‐ring widths and tree eccentricities in all directions were calculated and analysed in relation to the biogeomorphic impacts of trees. Some significant drivers of tree radial growth and sources of stem eccentricity were detected. The radial growth of trees on which deadwood was leaning was markedly limited. In contrast, trees with exposed roots expressed the highest growth rates. This clearly suggests that root exposure may not be an effect of ‘exogenous’ soil creep, but may rather result from individually intensifying tree growth due to fine‐scale disturbance dynamics. The response of biomechanical tree–soil interactions in tree radial growth weakened with increasing stem diameter, reflecting the stabilizing role of larger trees. The significance of calendar year on radial growth suggests seasonality in the dynamic component of soil creep. Tree eccentricity was observed mainly in the downslope direction, which suggests a relatively complex effect of biomechanics on stem tilting. © 2020 John Wiley & Sons, Ltd.
