“…The dynamics of such forests is driven by disturbances of minor intensity that kill single or eventually small groups of trees (Standovár and Kenderes 2003;Splechtna et al 2005;Zeibig et al 2005;Nagel and Svoboda 2008;Firm et al 2009;Trotsiuk et al 2012) and favour multilayered stand structures (Commarmot et al 2005;Westphal et al 2006;Kucbel et al 2010;Š ebková et al 2011;Motta et al 2011). Knowledge about the structure and dynamics of these forests may provide a foundation for activities to recreate such communities in areas where nature conservation and biodiversity protection are a priority (Winter and Brambach 2011;Winter 2012). It may also be useful as a model for close-to-nature silviculture (Meyer et al 2003;Jaworski 2004;Bauhus et al 2009).…”

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.

A novel but simple approach for describing stand structure in natural and managed forests driven by small-scaled disturbances is introduced. A primeval beech forest reserve in Slovakia and two beech stands in Germany with different management histories were studied, and their forest stand texture was analysed in terms of tree coordinates, stem diameter, and crown radius. Neighbouring trees of similar size with estimated contact of their crowns were assigned to tree groups. The study goal was to estimate the number and size of such homogeneous patches. In all cases, the number of tree groups in a particular diameter class decreased exponentially as group size increased. Single trees were predominant. Compared to simulated random tree distributions, the natural stand exhibited a more clumped distribution of small trees and more regular distribution of larger ones. The natural forest generally had smaller groups than the managed even aged stand, but the smallest group sizes were found in the uneven-aged selection forest. The simple analytical approach provided new spatial insights into neighbourhood relations of trees. The continuous scale from single trees to larger tree groups is an important achievement compared to other analytical methods applied in this field. The findings may even indicate a certain degree of selforganization in natural forests. Due to the limitations associated with each method or statistical models, a joint consideration of 1) gap dynamics, 2) forest developmental stages, and 3) size * Corresponding author.L. Drössler et al. 178classes of homogeneous tree groups is recommended. Relevant to forest practitioners, the size class distributions enhance an understanding of the complex stand structures in natural forests and therewith support an emulation of natural forest dynamics in managed beech forests.

“…A silvicultural practice based on the occurrence of the different eco-units or FDPs, established considering reference conditions, would sustain structural biodiversity conservation (Winter & Brambach 2011). The explicit inclusion of natural eco-units or FDPs in forest management planning could favor the incorporation of the often missing culmination and disintegration phases, fundamental to guarantee high levels of microhabitats and deadwood (Larrieu et al 2014b).…”

One of the objectives of forest conservation is the set aside of unharvested areas. However, the fragmentation and lack of connectivity of protected areas make the integration of conservation measures in productive forests essential. Strategies to integrate conservation of saproxylic biodiversity in forest management have been developed, but often considering only specific aspects or remaining preliminary otherwise. As the impact of climate change and anthropogenic stresses increases, the development and the synthesis of this approach is crucial. We reviewed the key literature on forest management for biodiversity conservation, integrating forest science perspective to provide a practical management framework. Our goal is to present a management framework that could contribute to the effective preservation of forest insect biodiversity at the landscape scale, without high economic efforts, and addressing the conflicts that still jeopardize sustainable forest management. The results of our review support the creation of micro-reserves inside productive forests, to support large reserves in landscape conservation strategies. Micro-reserves increase the resilience of forest ecosystems to anthropogenic disturbances, through the development of a heterogeneous structure, maximizing microhabitat availability. Modeling forest management and harvest on local natural disturbance would extend the benefits of spatio-temporal heterogeneity in productive forests. Variable retention harvest systems, applied at the landscape scale, are a feasible and adaptable strategy to preserve and increase biodiversity, safeguarding structural legacies such as senescent trees and deadwood inside the productive matrix. The operational shift, from the stand to the forest landscape, is fundamental to extend the benefits of conservation measures. The Forest Biodiversity Artery, composed by several micro-reserves or îlots de senescence, connected by corridors of habitat trees and deadwood, constitutes a network that would deliver old-growth forests attributes to the productive matrix. This planning instrument would support forest connectivity, and socioeconomic constraints.
