Application of climate-smart forestry – forest manager response to the relevance of European definition and indicators

Climate change impacts are an increasing threat to forests and current approaches to management. In 2020, Climate-smart Forestry (CSF) definition and set of indicators was published. This study further developed this work by testing the definition and indicators through a forest manager survey across fifteen member European countries. The survey covered topic areas of demographics, climate change impacts, definition and indicators assessment, as well as knowledge and communication. Overall, forest managers considered the threat of climate change to their forests as high or critical and 62% found the CSF definition clear and concise; however, the minority suggested greater simplification or nuance. Indicators were viewed as comprehensive but too numerous to integrate into management activities. Two highest ranking indicators were ‘Trees species composition’, and ‘Erosion protection and maintenance of soil condition’. Many managers were aware of suitable alternative species, but also stressed that greater resources should focus on exploring adaptable provenances. Demonstration sites and interactive guides were ranked highest for communication and dissemination; however, online multimedia tools and workshops were also ranked highly. Local perspectives on providing more relevant CSF ranged from silviculture systems, finance and funding, education and training, and social awareness, to tree species mixes and development of protective functions. In summary, forest managers were generally open to CSF, but required greater guidance and proof of application.Thanks to the support of the COST Action CLIMO “Climate-smart Forestry in Mountain regions – CA15226” for supporting the research and providing the networks and collaboration. We are grateful to all people who took part at survey providing answers and helpful comments.info:eu-repo/semantics/publishedVersio

Norway Spruce (Picea abies L.) Provenances Use Different Physiological Strategies to Cope with Water Deficit

Research Highlights: In this study, we found different regulatory mechanisms in two contrasting provenances of Norway spruce responding to progressive drought stress. Background and Objectives: In the context of climate and environmental changes, the following question of high importance in scientific studies is: How will Norway spruce, which forms a dominant component in European mountain and boreal forests, be able to cope with the increasing frequencies and intensities of drought periods? The aim of the study was to investigate the physiological responses of eight-month-old seedlings, as a most vulnerable phase of forest tree life, for different spruce provenances, to find out variable strategies in relation to controlled drought stress. Materials and Methods: We performed an experiment under controlled conditions with spruce seedlings from a climatologically warmer stand of 410 m above sea level (a.s.l.), and a moderately cool stand of 931 m a.s.l. The soil water content, leaf predawn water potential, the osmotic potential of needles, the relative water content of needles, and the photosynthetic performance and the contents of primary metabolites (proline and abscisic acid) were investigated as indicators of the spruce seedlings’ responses to water stress. The status of the indicators was analyzed at different temporal intervals, using repeated measures analysis of variance (ANOVA), reflecting the seedlings’ water conditions (early drought, drought, or recovery). On a daily basis, the differences among the indicators were tested with one-way ANOVA. A principal component analysis (PCA) was used to identify the provenance-specific responses of tree drought indicators in a multi-dimensional data set. Results: The responses to drought stress differed between the provenances. Whereas seedlings of ‘warm’ provenance from a low altitude performed a conservation strategy, with high amounts of accumulated abscisic acid and closing the stomata faster, the reactions of ‘cool’ provenance seedlings from a higher altitude were not so sensitive and the plants’ water supply and photosynthetic performance remained significantly higher. These findings indicate that a higher drought resistance in ‘cool’ provenance could be related to greater amounts of proline amino-acids, which are accumulated from the beginning of the drought simulation. Furthermore, proline accumulation resulting in increased stress tolerance is controlled through another mechanism than osmotic adjustment. Conclusions: The observed variations in the regulatory mechanisms used to develop adaptive strategies in different provenances are an important factor for seedling survival under a changing climate

Defining Climate-Smart Forestry

17openInternational coauthor/editorClimate-Smart Forestry (CSF) is a developing concept to help policymakers and practitioners develop focused forestry governance and management to adapt to and mitigate climate change. Within the EU COST Action CA15226, CLIMO (Climate-Smart Forestry in Mountain Regions), a CSF definition was developed considering three main pillars: (1) adaptation to climate change, (2) mitigation of climate change, and (3) the social dimension. Climate mitigation occurs through carbon (C) sequestration by trees, C storage in vegetation and soils, and C substitution by wood. However, present and future climate mitigation depends on the adaptation of trees, woods, and forests to adapt to climate change, which is also driven by societal change.Criteria and Indicators (C & I) can be used to assess the climate smartness of forestry in different conditions, and over time. A suite of C & I that quantify the climate smartness of forestry practices has been developed by experts as guidelines for CSF. This chapter charts the development of this definition, presents initial feedback from forest managers across Europe, and discusses other gaps and uncertainties, as well as potential future perspectives for the further evolution of this concept.openWeatherall, Andrew; Nabuurs, Gert-Jan; Velikova, Violeta; Santopuoli, Giovanni; Neroj, Bożydar; Bowditch, Euan; Temperli, Christian; Binder, Franz; Ditmarová, L’ubica; Jamnická, Gabriela; Lesinski, Jerzy; La Porta, Nicola; Pach, Maciej; Panzacchi, Pietro; Sarginci, Murat; Serengil, Yusuf; Tognetti, RobertoWeatherall, A.; Nabuurs, G.; Velikova, V.; Santopuoli, G.; Neroj, B.; Bowditch, E.; Temperli, C.; Binder, F.; Ditmarová, L.; Jamnická, G.; Lesinski, J.; La Porta, N.; Pach, M.; Panzacchi, P.; Sarginci, M.; Serengil, Y.; Tognetti, R
