“…This is a very important parameter (it is much more often applied, e.g., in agriculture) that often indicates the probability of tree survival under unfavorable environmental conditions. This can be demonstrated by comparing several Norway spruce stands with different soil water regimes and stand densities (Cermák & Nadezhdina 2011a, 2011b. Similar, but still modified information represents, e.g., cambium area index related ratio, CAI/( RAIabs/LAIsun), etc.…”

© iForest -Biogeosciences and Forestry Introduction 1Proper management of forest ecosystems from a biological perspective is dependent on classification of the natural environment for the purposes of phytotechnology (e.g., thinning operations) and forestry management. Functional management goals may include timber production as well as other important functions of forests in the landscape, such as water sources for people, but also for control of climate, maintenance of biological diversity, recreation, etc. for which importance often increases with time. Such functions have been working automatically in the past, but serious environmental impacts on forests associated with anthropogenic activities (e.g., air pollution, soil acidification) and global climatic change became apparent at the end of the 20 th century.Therefore long-term experience of foresters should be supplemented with additional objective information, which may be used to help solve new problems. This includes application of modern electronics, computers and other technologies, as well as collection of necessary data in the field especially pertaining to ecophysiology. This review provides only a brief description of methods suitable for studies at the whole tree and stand levels (and even higher levels). The methods are applicable under open forest conditions using mobile instrumentation approaches that can be used almost everywhere. They were tested in more than 60 sites and in over 50 woody species in Europe, USA and Australia. We focused on measurement and evaluation of macrostructure and water flow, because the maximum energy flow in ecosystems goes through water and water is the most frequent natural limiting factor of tree growth and functional states of whole trees and stands (if not considering polar regions and tops of high mountains). Ecologically oriented scientific fields and practically oriented field activities in forestry, arboristics, horticulture, hydrology, remote sensing and forensic engineering use many traditional and modern methods.Annual and seasonal stem growth are probably the most frequently studied processes in forestry. Usually institutions for forest management (IFM) base their practices on this valuable data on a large scale (e.g., national), which provide crucial information about timber production and yield. A great body of literature is available on this topic. However, strategy for the management of forest ecosystems in Europe elaborated over several centuries is focused on classification of the natural environment and determining potential natural vegetation and oriented not only toward production but also on preserving other important functions of forests in the landscape. A detailed version of this approach was successfully applied for over 80 years. The eventual impact of anthropogenic activities and global climatic changes led to development of ecophysiological methods applied to evaluate the functional state and development of forest ecosystems.These methods were usually overlooked in the past because prev...

“…An additional way of avoiding this dilemma of uncertainty is to reduce the time scale of management planning (Lode, Langensiepen, Roosaare, Schüler, & Koivusalo, 2011). In this sense, decisions should not be taken too early and several options should be considered, such as dealing with increasingly frequent droughts on one hand and increased runoff generation on the other hand.…”

Climate change has serious impacts on forest services with regard to the spatial and temporal distribution of water within catchments. Hence, combined forest and catchment management in a changing climate is a crucial concern for people and society. To assess hydrological processes and water resources in two forested headwater catchments in south-west Germany the physical based hydrological model ArcAPEX was calibrated to investigate climate change scenarios for the near (2021-2050) and far (2071-2100) future. Even though the trend in temperature is positive in most regional climate change scenarios for south-west Germany, the precipitation trend is quite ambiguous. Different precipitation scenarios give access to the possible bandwidth between water stress and flood generation. Our results can be used to describe water resources and discharge characteristics under conditions of different land use change scenarios.Management option for a sustainable forestry and flood mitigation will be to "spread the risk" by creating forests with a high biodiversity and a prioritization of forest services and functions. The principle is to find "no-regret" decisions. In this sense, final decisions should not be taken too early, and several options should be kept open, such as dealing with increasingly frequent droughts on one hand and increased runoff generation on the other hand. Thus, it should remain possible for forest and catchment management authorities to react to possible developments in an uncertain future.

“…Even in the regions that may not see significant changes in precipitation, warmer temperatures can increase water demands and evaporation, putting greater stress on water supplies (IPCC, 2014;Rowell & Jones, 2006;Schär et al, 2004;Škvarenina, Krížová, & Tomlain, 2004). Higher air temperatures are assumed to cause more pronounced drought impact on water loss from plants due to increased water vapour deficit, resulting in increased potential transpiration (Centritto, Tognetti, Leitgeb, Střelcová, & Cohen, 2011).…”

Drought and irrigation affect transpiration rate and morning tree water status of a mature European beech (Fagus sylvatica L.) forest in Central Europe

et al. 2018

Severity and frequency of recurrent droughts is likely to be amplified by recent climate changes and may adversely affect large areas of temperate forests. This study addresses the ecophysiological responses of a mature beech forest in Central Europe (Slovakia, 450 m a.s.l.) exposed to drought during the growing seasons of 2012–2014. Sap flow and stem circumference changes of European beech (Fagus sylvatica L.) were measured in two contrasting treatments (drought vs. irrigation). Limited water availability reflected in the morning tree water status (morning stem contraction, ΔW) significantly reduced transpiration. Trees stressed by drought in the years 2012 and 2013 showed remarkably lower values of morning ΔW than those in the irrigated group. This suggests (a) lower water potential of the stem‐conducting tissues and (b) increased use of internally stored water to maintain daily transpiration. Additionally, morning ΔW showed a close relationship with soil water potential, particularly in the nonirrigated trees. Potential evapotranspiration (PET) explained less variability in the transpiration of the control stand than that of the irrigated stand. The use of a simple analysis of covariance model comprising morning ΔW and PET interaction significantly increased the explained variability in transpiration in the control stand. Morning ΔW of mature beech trees seems to be a useful and easily obtainable non‐invasive bioindicator of their ability to reduce and regulate transpiration in relation to atmospheric evaporative demands in response to drought.
