“…There is also a strong emphasis on the transformations of forest stands that were degraded in the past (Stanturf et al 2014) or have undergone significant changes in the last 70 years. This happened mainly in the former socialist countries of Eastern and Central Europe, where nationalization of forest estates, vast plantations of conifers and subsequent restitutions in the 90s of the 20 th century took place (Bouriaud et al 2015;Podrázský et al 2014;Schulze et al 2014). In addition, anthropogenic changes in global ecosystems (Kareiva et al 2007;Ellis *Corresponding author.…”

The paper deals with development of the natural regeneration of even-aged spruce-beech forests during their transformation to uneven-aged stands with diversified structure at the Jedlový důl area in the Protected Landscape Area Jizerské hory Mts., Czech Republic. Shelterwood management system and free felling policy based on selection principles has been applied there since 1979 with the support of admixed tree species of the natural species composition, especially silver fir (Abies alba Mill.). The research was focuses on structure and development of natural regeneration with the emphasis on ungulate damage and interaction with tree layer from 1979 to 2015. In the course of 36 years, the regeneration structure was diversified towards the close-to-nature tree species composition, spatial and age structure. The number of regeneration recruits increased in average from 941 to 41,669 ind ha -1. During this period share of European beech (Fagus sylvatica L.) significantly (p < 0.01) increased (by 53.6%), while the share of Norway spruce (Picea abies [L.] Karst.) decreased (by 51.5%), such as damage caused by ungulate (by 61.4%) with the highest loses on sycamore maple (Acer pseudoplatanus L.), rowan (Sorbus aucuparia L.) and silver fir. Moreover, the parent trees had a significant negative influence on natural regeneration at smaller spacing (within a 1 -5 m radius from the stem). Both, regeneration potential and effective role of the tree layer during the forest transformation has been confirmed as important prerequisites for ongoing forest transformation.

“…In the present paper, we integrated the results of various case studies (Hengeveld et al 2014;Andersson et al 2014;Maroschek et al 2014;Zell and Hanewinkel 2015;Bouriaud et al 2014-further referred to as case studies) into the EFISCEN modelling framework to assess climate change consequences and, most importantly, study alternative management responses at the European level. Adaptive management in the sense of continuous improvement and re-planning, as developed and applied at the case studies, cannot be implemented at the European scale.…”

We present for the first time a study on alternative forest management at the European scale to account for climate change impacts. We combine insights into detailed studies at high resolution with the actual status of the forest and a realistic estimate of the current management practices at large scale. Results show that the European forest system is very inert and that it takes a long time to influence the species distribution by replacing species after final felling. By 2070, on average about 36 % of the area expected to have decreased species suitability will have changed species following business as usual management. Alternative management, consisting of shorter rotations for those species and species planting based on expected trends, will have increased this species transition to 40 %. The simulated forward-looking alternative management leads to some reduction in increment, but does not influence the amount of wood removed from the forest.Northern Europe is projected to show the highest production increases under climate change and can also adapt faster to the new (proposed) species distribution. Southwest Europe is expected to face the greatest challenge by a combination of a predicted loss of production and a slow rate of management alteration under climate change.

“…Spatial and temporal planning and decisions on the intensity of management alternatives take into consideration a range of options, such as species mixture, stand structure, thinning regime, and rotation time. Complex alternatives, e.g., maintaining a desirable forest structure, may be considered as an adaptive strategy, e.g., maintaining mixed broadleaved forests in Romania (Walentowski et al 2013, Bouriaud et al 2015. BAU typically refers to the stand scale, but adaptive management options may encompass landscape-level structures, e.g.…”

Hanewinkel. 2017. A framework for modeling adaptive forest management and decision making under climate change. ABSTRACT. Adapting the management of forest resources to climate change involves addressing several crucial aspects to provide a valid basis for decision making. These include the knowledge and belief of decision makers, the mapping of management options for the current as well as anticipated future bioclimatic and socioeconomic conditions, and the ways decisions are evaluated and made. We investigate the adaptive management process and develop a framework including these three aspects, thus providing a structured way to analyze the challenges and opportunities of managing forests in the face of climate change. We apply the framework for a range of case studies that differ in the way climate and its impacts are projected to change, the available management options, and how decision makers develop, update, and use their beliefs about climate change scenarios to select among adaptation options, each being optimal for a certain climate change scenario. We describe four stylized types of decision-making processes that differ in how they (1) take into account uncertainty and new information on the state and development of the climate and (2) evaluate alternative management decisions: the "no-change," the "reactive," the "trend-adaptive," and the "forward-looking adaptive" decision-making types. Accordingly, we evaluate the experiences with alternative management strategies and recent publications on using Bayesian optimization methods that account for different simulated learning schemes based on varying knowledge, belief, and information. Finally, our proposed framework for identifying adaptation strategies provides solutions for enhancing forest structure and diversity, biomass and timber production, and reducing climate change-induced damages. They are spatially heterogeneous, reflecting the diversity in growing conditions and socioeconomic settings within Europe.
