“…Tree crown morphology was significantly influenced by interspecific competition. Vertical crown extension of Maritime pine was greater in mixed versus pure stands, especially in larger trees (Figure 4.3), which is consistent with studies showing that interspecific interactions affect species-specific allometric relationships (Forrester et al, 2017a;Pretzsch, 2014). This may signify niche partitioning processes resulting from the slow, continual feedback between structure, environment and tree growth in mixed stands (Pretzsch, 2014).…”

“…Most studies on mixed forests in temperate zones focus on mixtures that combine species with more diverse traits (shade tolerance, height growth rate, crown structure, leaf phenology, root depth) (Forrester, 2014;, due to the higher probability of complementarity (reduced competition and facilitation) in the allocation and efficient use of available resources among species (Bauhus et al, 2017a;Forrester, 2014;Kelty, 2006). Since competition among species increases as species niches overlap, when organisms occupy the same spatial and temporal habitats and use the same resources, the strength of interspecific competition is affected and they could interact as if they were the same species (functional redundancy concept) (Naeem, 1998;Rosenfeld, 2002).…”

“…Although, the strength of inventory datasets is the representativeness of the inferences, e.g., comparison of stand productivity of mixed versus monospecific stands and the correlation with site conditions is representative of a population (del Río and Sterba, 2009;Toïgo et al, 2015). The comprehensive quantification of the system properties and process in mixed stands from the analysis of inventory data is limited by the abovementioned data constraints and possible confounding factors that require particular attention when analyzing species-mixing effects (Bauhus et al, 2017a;Vilà et al, 2005). As a complementary alternative, observational studies based on temporary plots can help to exclude or control the influence of other factors in the analysis.…”

“…In other words, the type and intensity of interactions, along with species functional traits and stand structure, drive the effects of tree species richness on ecosystem functioning for a particular species mixture at a given site (Forrester and Bauhus, 2016). For example, complementary traits and functions among species are likely to be higher in forests with shade-tolerant and deep-rooting deciduous species -which cover a wide range of functional typesthan in forests with the same number of species but consisting only of coniferous evergreens (Bauhus et al, 2017a).…”

I am deeply grateful to all my friends in Palencia for making my time there special and for revealing me the secret wonders of a small city in the middle of a plateau. Will never forget about the crunchy "sopas de ajo". Thanks to my lab mates Wilson, Jorge, Nico and Sara for all the modeling and programming help, but mainly for the team complaining and laughing. I enjoyed all the scientific discussions but mostly the random talks with all my Uni friends. Thanks to them for sharing day-today life with countless amounts of coffee and chasquis; this work would be impossible without them. Thank you,

Understanding tree and stand growth dynamics in the frame of climate change calls for large-scale analyses. For analysing growth patterns in mountain forests across Europe, the CLIMO consortium compiled a network of observational plots across European mountain regions. Here, we describe the design and efficacy of this network of plots in monospecific European beech and mixed-species stands of Norway spruce, European beech, and silver fir.First, we sketch the state of the art of existing monitoring and observational approaches for assessing the growth of mountain forests. Second, we introduce the design, measurement protocols, as well as site and stand characteristics, and we stress the innovation of the newly compiled network. Third, we give an overview of the growth and yield data at stand and tree level, sketch the growth characteristics along elevation gradients, and introduce the methods of statistical evaluation. Fourth, we report additional measurements of soil, genetic resources, and climate smartness indicators and criteria, which were available for statistical evaluation and testing hypotheses. Fifth, we present the ESFONET (European Smart Forest Network) approach of data and knowledge dissemination. The discussion is focussed on the novelty and relevance of the database, its potential for monitoring, understanding and management of mountain forests toward climate smartness, and the requirements for future assessments and inventories.In this chapter, we describe the design and efficacy of this network of plots in monospecific European beech and mixed-species stands of Norway spruce, European beech, and silver fir. We present how to acquire and evaluate data from individual trees and the whole stand to quantify and understand the growth of mountain forests in Europe under climate change. It will provide concepts, models, and practical hints for analogous trans-geographic projects that may be based on the existing and newly recorded data on forests.

Mountain forests in Europe have to face recently speeding-up phenomena related to climate change, reflected not only by the increases in the mean global temperature but also by frequent extreme events, that can cause a lot of various damages threatening forest stability. The crucial task of management is to adapt forests to environmental uncertainties using various strategies that should be undertaken to enhance forest resistance and resilience, as well as to maintain forest biodiversity and provision of ecosystem services at requested levels. Forests can play an important role in the mitigation of climate change. The stand features that increase forest climate smartness could be improved by applying appropriate silvicultural measures, which are powerful tools to modify forests. The chapter provides information on the importance of selected stand features in the face of climate change and silvicultural prescriptions on stand level focusing to achieve the required level of climate smartness. The selection of silvicultural prescriptions should be also supported by the application of simulation models. The sets of the various treatments and management alternatives should be an inherent part of adaptive forest management that is a leading approach in changing environmental conditions.
