In many parts of Europe, close-to-nature silviculture (CNS) has been widely advocated as being the best approach for managing forests to cope with future climate change. this review, we identify and evaluate six principles enhancing adaptive capacity European temperate in a changing climate: (1) increase tree species richness, (2) structural diversity, (3) maintain genetic variation within species, (4) resistance individual trees biotic abiotic stress, (5) replace high-risk stands (6) keep...
Mixing of complementary tree species may increase stand productivity, mitigate the effects drought and other risks, pave way to forest production systems which be more resource-use efficient stable in face climate change. However, systematic empirical studies on mixing are still missing for many commercially important widespread combinations. Here we studied growth Scots pine (Pinus sylvestris L.) European beech (Fagus sylvatica mixed versus pure stands 32 triplets located along a...
The development of forestry as a scientific and management discipline over the last two centuries has mainly emphasized intensive operations focused on increased commodity production, mostly wood. This “conventional” forest approach typically favored production even-aged, single-species stands. While alternative regimes have generally received less attention, this been changing three decades, especially in countries with developed economies. Reasons for change include combination new...
Whereas there is evidence that mixed-species approaches to production forestry in general can provide positive outcomes relative monocultures, it less clear what extent multiple benefits be derived from specific alternatives. To such insights requires evaluations of an encompassing suite ecosystem services, biodiversity, and forest management considerations provided by mixtures monocultures within a region. Here, we conduct assessment Sweden contrasting even-aged Norway spruce (Picea...
Summary There is increasing evidence that species diversity enhances the temporal stability (TS) of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony responses environmental conditions was found one main drivers this stabilizing process. However, mixing on productivity, relative importance associated mechanisms, remain poorly understood forest communities. We investigated way influenced TS Pinus...
Abstract When tree‐species mixtures are more productive than monocultures, higher light absorption is often suggested as a cause. However, few studies have quantified this effect and even fewer examined which light‐related interactions most important, such the effects of species on tree allometric relationships crown architecture, differences in vertical or horizontal canopy structure, phenology deciduous mixing size stand density. In study, measurements sizes structures were combined with...
Abstract Past failures of monocultures, caused by wind-throw or insect damages, and ongoing climate change currently strongly stimulate research into mixed-species stands. So far, the focus has mainly been on combinations species with obvious complementary functional traits. However, for any generalization, a broad overview mixing reactions functionally different tree in proportions, patterns under site conditions is needed, including assemblages rather similar demands resources such as...
Abstract The increasing disturbances in monocultures around the world are testimony to their instability under global change. Many studies have claimed that temporal stability of productivity increases with species richness, although ecological fundamentals mainly been investigated through diversity experiments. To adequately manage forest ecosystems, it is necessary a comprehensive understanding effect mixing on and way which influenced by climate conditions across large geographical areas....
Mixed-species stands have been found to be more productive than would expected from the performance of their component species in monocultures due facilitation and complementarity between species, although these interactions depend on combination present. Our study focuses monospecific mixed-species Scots pine Norway spruce using 20 triplets established nine countries along a climatic gradient across Europe. Differences mean tree stand characteristics, productivity structure were assessed....
The study investigated the possibility to transform normal young Norway spruce (Picea abies (L.) Karst) forests develop more heterogeneous stand structures, aiming for multi-layered forest in long run. On three sites central and south Sweden, 60 per cent of basal area was removed by thinning mainly medium-sized trees leaving smallest largest trees. Over next 50 years, future development simulated using a single-tree growth model. Simulations were run with without ingrowth. An additional...
Pine-spruce forests are one of the commonest mixed forest types in Europe and both tree species very important for wood supply. This study summarized nine European studies with Scots pine Norway spruce where a mixed-species stand monocultures were located an experimental set-up. Overyielding (where growth was greater than average monocultures) relatively common often ranged between 0% 30%, but could also be negative at individual sites. Each site demonstrated consistent patterns mixing...
Heterogeneity of structure can increase mechanical stability, stress resistance and resilience, biodiversity many other functions services forest stands. That is why silvicultural measures aim at enhancing structural diversity. However, the effectiveness potential structuring may depend on site conditions. Here, we revealed how stand determined by quality results from site-dependent partitioning growth mortality among trees. We based our study 90 mature, even-aged, fully stocked monocultures...
There is a lack of experimental studies comparing the forest production mixed tree species stands and monocultures. As case study, in 1994 an experiment was established afforestation landscape southern Sweden with 66 plots: 18 planted single (including most native Swedish trees, plus Populus Larix hybrids) 48 various non-replicated mixtures. Fifteen years after planting, stand growth did not differ significantly between mixtures However, monocultures exhibit higher variation levels relative...
Forest management in Sweden can be characterized by even-aged silviculture heavily relying on three established harvest regimes: clearcutting, the seed-tree method, and shelterwood system. Less intense, small-scale retention systems such as single tree group selection are rarely used. In addition, natural regeneration dynamics without enrichment planting have barely been studied. Consequently, this study examined establishment a multi-layered Pinus sylvestris-Picea abies forest stand...
A novel but simple approach for describing stand structure in natural and managed forests driven by small-scaled disturbances is introduced. primeval beech forest reserve Slovakia two stands Germany with different management histories were studied, their texture was analysed terms of tree coordinates, stem diameter, crown radius. Neigh-bouring trees similar size estimated contact crowns assigned to groups. The study goal estimate the number such homogeneous patches. In all cases, groups a...
Purpose Recent climate scenarios indicate that Sweden's southern region, Götaland, will experience significant change over the coming century. Swedish forestry policy guidelines emphasize need for risk spreading to reduce potential adverse impacts of these changes. Risk is defined here as reducing vulnerability a social‐ecological system by increasing heterogeneity its ecological components. may be achieved through diversification tree species currently relied upon sector. The purpose this...
