“…The regression model (y = ax b ) of variation in the basal area of live trees in relation to plot size proposed in this study is very similar to that fitted by Král et al (2010a) (a = 0.073 vs. 0.80, b = -0.49 vs. -0.47) for other three beech-dominated natural forests from the region of Central Europa. These matching results suggest that the relations identified are characterised by a considerable generality.…”

The research objective was to provide a generalised model of spatial variation in the basal area of live and dead trees in primeval beech-fir-spruce forests in the Western Carpathians region. The study was carried out in three primeval stands located in the Polish part of the massif. In each research area, small sample plots (0.015 ha) were localised in a regular 20 9 20 m grid covering approximately 10 ha. In each sample plot, the diameters at breast height (d 1.3 ) and species of all live and dead trees were recorded. The spatial pattern was tested statistically using a variance-to-mean ratio on a single sample plot scale (0.015 ha) and a paired-plot approach for the distance range between 20 and 200 m. Simulation techniques were then used to model variation in the basal area of live and dead trees dependent on spatial scale. The spatial patterns of live and dead canopy trees (d 1.3 [ 50 cm) were regular when analysed on a single sample plot scale (0.015 ha) but most often random at distance lags C20 m. The spatial variability in the basal area of live and dead trees also tended to be random. These results suggest that the patchmosaic assumption is inapplicable to the primeval beechfir-spruce stands in the Western Carpathians. In all three stands studied, the basal area recorded on the plots 0.015 ha in area had a very similar pattern of variation, which could be generalised as either a truncated normal distribution (live trees) or a negative exponential distribution (dead trees). The bell-shaped frequency distribution of the basal area of live trees suggests a dynamics model in which extreme values of biomass accumulation are rare and disturbances frequent but quickly balanced by stand increment.

“…Primeval European beech forests have higher stand diversity (at the level of structural and tree species diversity) than commercial forests on comparable sites (Král et al 2010). All the presented results above obviously support this statement relating to the key importance of knowledge in forest dynamics in stand-scale for conserving forest biodiversity.…”

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.

“…The locations and selected properties (tree species, diameter at breast height -DBH, health condition -dead standing or lying tree, broken tree, stump, etc.) of all trees with DBH ≥ 10 cm were recorded within the 74.2 ha area, and a stem position map including 23 881 standing or lying tree trunks was created (for details, see Král et al, 2010a). Precise stem positions, which were measured from the centres of the regular network with a precision of circa 0.5 m, were connected to soil maps and served as the basis for spatial analyses of releases in core series (see Sect.…”

Disturbances can control fine-scale pedodiversity in old-growth forests: is the soil evolution theory disturbed as well?

Abstract. Biota–soil interactions in natural ecosystems are the subject of considerable research. Our hypothesis is that individual trees play a significant role through biomechanical and biochemical disturbances affecting soil formation in temperate forests, resulting in a complex spatial pattern of disturbance regimes and a close relationship between disturbance histories and soil units. In Žofínský Prales (Czech Republic) – the fourth oldest, continuously protected reserve in Europe and the first site of global research network SIGEO (Smithsonian Institution Global Earth Observatories) in continental Europe – we compared extensive dendrochronological, soil and pit–mound microtopography data both temporally and spatially from an area of anthropogenically unaffected 42 ha collected from 2008–2012. These data sets differ in terms of information complexity and length of memory: tree cores contain complex information about the disturbance history of the past 350 years, footprints of disturbances from the uprooting of a specific tree can persist 1700 years, and soils represent an extensive composite phenotype that has been developing for at least the entire postglacial period (10 500 years). On average, 6.18–13.41% of the canopy on individual soil units was disturbed per decade. Even though the "backbone" of key events in the development of the forest ecosystem remained the same (e.g. the 1870s, 1880s and 1980s), the internal structure of disturbance history often differed among soil units; the most exceptional were Gleysols and Histosols, where important feedback from soil to trees was expected. However, the characteristics of treethrow dynamics as well as the frequencies of stronger releases in core series also significantly differed along a gradient of terrestrial soil weathering and leaching (Haplic Cambisols – Dystric Cambisols – Entic Podzols – Albic Podzols). These results suggest the existence of several disturbance regimes within the forest, controlling fine-scale pedodiversity.
