“…Regional studies conducted in several countries, with the aim of predicting which forests would be more suitable for future conditions, have come up with similar recommendations concerning reductions in spruce monocultures, and giving preference to mixed forests with a higher proportion of deciduous tree species, particularly the European beech [44][45][46].…”

Abstract:The regional effects of climate change on forest ecosystems in the temperate climate zone of Europe can be modelled as shifts of forest vegetation zones in the landscape, northward and to higher elevations. This study applies a biogeographical model of climate conditions in the forest vegetation zones of the Central European landscape, in order to predict the impact of future climate change on the most widespread tree species in European deciduous forests-the European beech (Fagus sylvatica L.). The biogeographical model is supported by a suite of software applications in the GIS environment. The model outputs are defined as a set of conditions -climate scenario A1B by the Special Report on Emission Scenarios (SRES) for a forecast period, for a specified geographical area and with ecological conditions appropriate for the European beech, which provide regional scenarios for predicted future climatic conditions in the context of the European beech's environmental requirements. These predicted changes can be graphically visualized. The results of the model scenarios for regional climate change show that in the Czech Republic from 2070 onwards, optimal growing conditions for the European beech will only exist in some parts of those areas where it currently occurs naturally. Based on these results, it is highly recommended that the national strategy for sustainable forest management in the Czech Republic be partly re-evaluated. Thus, the presented biogeographical model of climate conditions in forest vegetation zones can be applied, not only to generate regional scenarios of climate change in the landscape, but also as a support tool for the development of a sustainable forest management strategy.

“…Whereas, for example, König (1996) and von Lüpke and Spellmann (1999) did not find a positive effect of tree mixture on stand resistance in the case of Norway spruce and European beech and concluded that stand type is not as important as soil type. Schütz et al (2006) and Griess et al (2012) reported evidence of European beech stabilizing admixed Norway spruce in mixed stands. This finding was considered for SMI r of mixed stands.…”

“…In this case, the risk of the mixed stand is defined by the risk of the main stand, because a failing of admixed species does not affect total stand survival. Moreover, the specific risk of the admixed species may even decrease (Griess et al 2012). However, when species comprising a lower risk are admixed to a main stand, then the risk of stand loss of the mixed stand will be reduced proportionally, since admixed species should not be affected by calamities in the same extent as the main stand.…”

How to quantify forest management intensity in Central European forests

Existing approaches for the assessment of forest management intensity lack a widely accepted, purely quantitative measure for ranking a set of forest stands along a gradient of management intensity. We have developed a silvicultural management intensity indicator (SMI) which combines three main characteristics of a given stand: tree species, stand age and aboveground, living and dead wooden biomass. Data on these three factors are used as input to represent the risk of stand loss, which is a function of tree species and stand age, and stand density, which is a function of the silvicultural regime, stand age and tree species. Consequently, the indicator consists of a risk component (SMI r ) and a density component (SMI d ). We used SMI to rank traditional management of the main Central European tree species: Norway spruce (Picea abies [Karst.] L.), European beech (Fagus sylvatica L.), Scots pine (Pinus sylvestris L.), and oak (Quercus robur L. and Quercus petraea L.). By analysing SMI over their whole rotation period, we found the following ranking of management intensity: oak\beech\pine(spruce. Additionally, we quantified the SMI of actual research plots of the German Biodiversity exploratories, which represent unmanaged and managed forest stands including conifer forests cultivated outside their natural range. SMI not only successfully separate managed from unmanaged forests, but also reflected the variability of forest management and stand properties across the entire sample and within the different management groups. We suggest using SMI to quantify silvicultual management intensity of stands differing in species composition, age, silvicultural system (even-aged vs. uneven-aged), thinning grade and stages of stand conversion from one stand type into another. Using SMI may facilitate the assessment of the impact of forest management intensity on biodiversity in temperate forests.

“…For example, mono-specific plantations of Norway spruce (Picea abies (L.) Karst), one of the most commercially valuable tree species in Europe, are declining (Jonard et al 2012;Bošel'a et al 2014). However, the survival of Norway spruce can be increased when growing in mixed-forest (Griess et al 2012). The introduction of European beech (Fagus sylvatica L.) into coniferous mono-specific stands plays a central role in current forest transition strategies (Geßler et al 2007).…”

Enhanced levels of CO 2 affected both the nutrition and morphology of both species. The effect of interspecific competition was dependent on the species identity but not on the CO 2 level. AbstractThe interest in adaptive forest strategies to overcome predicted scenarios of climate change is increasing worldwide. An example of these strategies is the introduction of native species into mono-specific plantations. However, to fully consider this option/strategy, a higher understanding of the responses of forest tree species to concurrent biotic and abiotic factors is needed. The aim of the present study was to assess nutritional and morphological adjustments of individuals of European beech (Fagus sylvatica L.) and Norway Spruce (Picea abies (L.) Karst) growing at enhanced levels of CO 2 and with different proportions of con-specific individuals in its vicinity.Individuals that grew at elevated CO 2 levels showed higher values of relative growth rate (RGR), total twig dry biomass and root biomass, and lower values of leaf area ratio, leaf N and Mg concentrations and soil nutrient concentrations. Individuals of Norway spruce growing in the vicinity of high proportions of European beech showed a reduction in the allocation of biomass to foliar tissue and lower values of RGR and root biomass. European beech, by contrast, showed a limited response to Norway spruce presence and higher capacity in the exploitation of space both above-and belowground. In conclusion, the lower response of European beech to both environmental factors suggests that the introduction of European beech into Norway spruce stands could be a feasible option in current forest transition strategies.
