“…This monitoring can be straightforward using automatic dendrometers. These instruments measure stem radial variation composed of diurnal rhythms of water storage depletion and replenishment (Kozlowski and Winget, 1964;Herzog et al, 1995;Offenthaler et al, 2001) and seasonal tree growth (Dünisch and Bauch, 1994;Downes et al, 1999;Tatarinov and Čermák, 1999;Tardif et al, 2001;Deslauriers et al, 2003b;Bouriaud et al, 2005). Because of the reversible stem shrinking and swelling, dendrometers have been criticized when used to measure short-term growth rates (Mäkinen et al, 2003;Zweifel and Häsler, 2001).…”

Dendrometer and intra-annual tree growth: What kind of information can be inferred?

Dendrometer measurements provide time series composed of the rhythm of water storage fluctuations over the year and seasonal tree growth. For slow-growing trees however, difficulties have been found in the identification of crucial events such as growth onset, stem growth period and cessation, rendering it necessary to define what can be measured and at which time scale. The time scale mean the time interval (from one day to one month) at which stem radius variation is extracted. In this study, two latewood cells were produced in August at both altitudes, the variability in stem radius changes was higher than the amount of growth in terms of cell-wood production. For slow-growing species of a cold environment, an understanding of the growth period, assessed with several time scales, is necessary when using time series of stem radius variation to perform growth and climate relationships. The period used for growth and climate analysis should correspond only with the main period of stem growth.

“…Various insights into tree growth can be obtained by using high-resolution dendrometers, including the understanding of short-term growth responses to changing environmental conditions [18]. Although the advantages of dendrometers are very notable, it is difficult to determine the initiation and cessation of wood formation by the method [25] because the measurements obtained from dendrometers are composed of reversible diurnal rhythms of water depletion and replenishment (i.e., the overall shrinking and expanding of xylem, phloem, and periderm) [26][27][28], and irreversible seasonal tree growth (i.e., the new cell formation and development) [20,[29][30][31][32]. Here, we name stem radial increment by the reversible diurnal change as the false growth, and stem radial increment by the irreversible diurnal change as the true growth.…”

Picea crassifolia Komarov (Qinghai spruce) is an endemic tree species in China and is widespread in the Qilian Mountains, in northwestern China. High temporal resolution changes of Qinghai spruce tree stem growth remain poorly investigated and the relationships between the species growth and climate are still not completely understood. In this study, we assessed the daily and seasonal stem radial variations, and analyzed the relationships between stem radial increment of Qinghai spruce and environmental factors during the main growing period (June-August). We have found that the stem radial variations of Qinghai spruce can be divided into three phases according to the air temperature and that Qinghai spruce has two diurnal cycle patterns. The main growing period of Qinghai spruce is 30 May-31 August according to micro-core measurements, in conformity with the daily mean air temperature keeping above 5 • C. Precipitation and relative humidity have positive effects on the growth of Qinghai spruce, and we develop a multiple linear regression model that can explain 63% of the stem radial increment over the main growing period.

“…35, middle panel). All similar dataloggers provide seasonal records of data (Tatarinov & Cermák 1999, Tatarinov et al 2005. Electronic loggers can also record diurnal changes in stem radius or circumference, as illustrated in sample records measured at 2 heights in a sample tree (Fig.…”

“…Water may become inaccessible during long, severe frosts or when the whole tree storage is depleted during warm winters. Seasonal episodes of trunk growth are sufficiently characterized by band dendrometers (Tatarinov & Cermák 1999, Tatarinov et al 2005), but diurnal changes can help to elucidate the causes of the measured changes.…”

© 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...
