“…If the crown width is too large, the photosynthesis of the regeneration trees is blocked and cannot grow well. Tree species richness was one of the main drivers affecting regeneration (Adam et al, 2013;Tinya et al, 2019). In this study, the species richness index of whole stand was positively correlated with the density and species richness of the regeneration trees.…”

Background: Regeneration is an extremely important and complex ecological process, which is disturbed by many factors. The current stand structure has an important influence on regeneration. The aim of this study is to provide theoretical reference for improving the regeneration capacity subtropical evergreen broad-leaved forest and formulating management measures of regeneration restoration.Methods: A permanent plot of 100m × 100m was set up in the evergreen broad-leaved forest of Tianmu Mountain National Nature Reserve, Zhejiang Province, China. The plot was divided into 25 survey units of 20m × 20m by the adjacent grid survey method, and all the trees in the plot were investigated. The tree height, DBH, crown width, density, species richness index, aggregation index, competition index and mingling of each forest stratum were used as the stand structure index. The tree height, DBH, crown width, density and species richness index of regeneration trees were used as regeneration indicators. Redundancy analysis (RDA) was used to explore the relationship between forest strata structure and regeneration of evergreen broad-leaved forest. Results: In the whole stand, DBH, tree species richness index and crown width were the main structure factors affecting regeneration. In the upper forest stratum, the tree height was the main structure factor affecting regeneration. In the middle forest stratum, the tree species richness index and crown width were the main factors affecting regeneration. In the lower forest stratum, crown width, competition index, tree height and tree species richness index were the main factors affecting regeneration. The effects of tree species richness index and crown width on regeneration in the whole stand were mainly reflected in the middle and lower forest strata in each forest stratum. Conclusions: The influencing order of each forest stratum structure on regeneration was: lower forest stratum > middle forest stratum > upper forest stratum. Different regeneration indicators had different responses to the main stand structure indices, while the young tree height and DBH, and the tree species diversity and density of regeneration trees were most affected by the main stand structure indices. In order to promote the regeneration of evergreen broad-leaved forest in the future, different management measures should be taken for different forest strata, and the threshold value of each index should be controlled.

“…The success of both natural and artificial regeneration in European temperate forests is affected by a large number of biotic and abiotic factors. Gap dynamics, light intensity, soil humidity, climate-induced disturbance regimes as well as soil properties and the composition of the regeneration layer all modulate regeneration ( Emborg, 1998 ; Svoboda et al, 2010 ; Muscolo et al, 2014 ; Tinya et al, 2019 ). Furthermore, the impact of deer browsing on tree regeneration is a common and widely discussed problem in many European temperate and boreal forest types ( Ammer, 1996 ; Barančeková et al, 2007 ).…”

Invasive alien species (IAS) are one of the major threats to global and local biodiversity. In forest ecosystems, the threats caused by IAS include hybridization, transmission of diseases and species competition. This review sets out to analyze the impact of alien plant species on forest regeneration, which we consider to be one of the key stages in tree ecology for the survival of forest ecosystems in the future. The focus of the study is directly relevant to practitioners, forest managers and the conservation management of forests. With this systematic review, we aim to provide an overview of 48 research studies reporting on the impact and/or management of IAS in European temperate forests. We followed a multi-step protocol for compiling the publications for the literature review, with nine search queries producing a total of 3,825 hits. After several reduction rounds, we ended up with a grand total of 48 papers. We identified 53 vascular plant species having a negative influence on forest regeneration in Central European forests. In total, 21 tree species are reported to be impacted by IAS in 24 studies. The results of the review synthesis show that five impact mechanisms affect the regeneration success of native tree species: competition for resources, chemical impact on regeneration, physical impact on regeneration, structural impact on regeneration and indirect impact through interaction with other species. We identified in our synthesis management measures that have been recommended for application at different stages of biological invasions. The associated costs and required resources of management measures are under-reported or not accessible by reviewing the scientific literature. We can thus conclude that it is very import to improve the links between science and practical forest management. We expect that this review will provide direction for invasive plant species research and management aimed at protecting biodiversity in European temperate forest ecosystems.

“…The occurrence of white birch is most concentrated on Histosols and in a transitional area towards Podzols and Gleysols with the lowest pH values, where other deciduous trees are unable to grow. While the white birch is a stenoec species, the silver birch is able to compete with oaks, willows and aspens in loaded conditions, but the its humus properties rather resemble coniferous than deciduous trees on mesophilic soils (Vacek et al, 2013;Cools et al, 2014;Tinya et al, 2019).…”

Combined effect of environmental change and management variability leads to reduced soil diversity in homogenous forest stands. On the other hand, forest soil diversity is maintained with rich tree species composition. In this study, focus has been put on deriving urgency to change forest tree species composition in order to increase soil diversity in biogeographic regions with uneven impact of environmental change. The relation of forest tree species and soil diversities was compared between the periods of dominant sulphur deposition (1985–1994) and the period of regional environmental change (2003–2012) in the Czech Republic (Central Europe; 78 866 km2; 115–1602 m n.m.). Forest tree species and soil diversities were assessed using linear regression, discrimination analysis and geographically weighted regression including residue analysis. The effect of spatial differences of acid deposition on soil properties, though, decreased, still dependencies between the diversity of bedrock, soils and forest tree species increased significantly. Only 12.9 % of forests in the territory of the CR have optimum tree species diversity. The total of 65.9 % of forest require highly or moderately urgent transformation. An increase in spatial dependencies between soil and tree species diversities confirms the importance of site differentiation in forest transformation.
