We investigated the temporal variability of intra-annual wood density variations in European beech (Fagus sylvatica L.) in a valley in southwestern Germany. Samples were collected from 11 beech trees growing at north-west (NW) and south-west (SW) exposed slopes. High-frequency densitometry was used to obtain wood density profiles. We converted radial positions within these profiles to a seasonal time scale over automatic point dendrometer data for the period 2001-2006. Temporally resolved wood density data was analyzed both visually and statistically, using correlation analysis and multiple li

The health and vitality assessment of each single tree is one of the most important actions for an optimal urban forest management program. The development of new technology able to continuously monitor the tree vitality and underlying trends, could help reduce the frequency of the monitoring assessment and help overcome problems related to the rapid decline in tree health. Our aim was to test the suitability of point dendrometers in evaluating the tree vitality trend through high resolution stem cycle analyses. To achieve this objective, we installed point dendrometers on twelve Pinus radiata

Abstract The purpose of a dendrometer is to measure tree diameter. Contact and noncontact dendrometers accomplish this task by collecting different metrics, including girth or distance between tangent points on a tree stem. Many dendrometers have been developed in the last quarter century and many have been retired. This article summarizes instrument developments and application results, contains an interpretation of the results, and provides guidance for dendrometer selection. FOR. SCI. 46(4):570–576.

Abstract Dendrometers are being increasingly used to measure stem radius changes in trees and to unravel the mechanisms underlying stem daily rhythms of radial expansion and contraction. Nevertheless, automated dendrometers have not been often used to measure root radius dynamics, their relationship with environmental variables and the influence of endogenous processes, especially in drought-prone Mediterranean areas. Here, we measured root radius dynamics of two coexisting oak species (the evergreen Quercus ilex L. and the deciduous Quercus faginea Lam). Our goals were to describe annual, sea

Abstract State-of-the-art technique for measuring height of leaning, forked, crooked, or curved trees is briefly reviewed. The most efficient method employs an expensive tiltable range- finding dendrometer which can measure various types of leaning or nonlinear trees. However, a much less expensive tiltable nonranging hypsometer can be employed on straight leaning trees. This recently developed technique uses spherical triangulation observation points to eliminate bias attributable to lean in the slant plane toward or away from the observer.

ABSTRACTTree diseases are a growing threat to ecosystem service provision by trees in cities and towns globally. Phytophthora is a widespread genus of plant pathogens (oomycetes) that have contributed to significant tree mortality worldwide; however, there has been little research into the impact of Phytophthora infection on urban trees or on ecosystem services important for urban populations, such as urban cooling. This study utilizes a network of Internet‐of‐Things linked sap flow sensors and point dendrometers collecting data every ~10 min throughout the growing season, combined with ground

Abstract Climate change and the global economy impose new challenges in the management of food-producing trees and require studying how to model plant physiological responses, namely growth dynamics and phenology. Hazelnut (Corylus avellana L.) is a multi-stemmed forest species domesticated for nut production and now widely spread across different continents. However, information on stem growth and its synchronization with leaf and reproductive phenology is extremely limited. This study aimed at (i) defining the sequencing of radial growth phases in hazelnut (onset, maximum growth and cessatio

IntroductionUnderstanding the stress recovery of trees, particularly with respect to increasing droughts due to climate change, is crucial. An often-overlooked aspect is how short versus long drought events of high intensity (i.e., low and high stress dose) result in stress damage and affect post-stress recovery.MethodsThis study examines the stress and recovery dynamics of 3-year-old Picea abies following a short drought (n = 5) of 18 days or a long drought (n = 9) of 51 days during late summer. We particularly assessed how the recovery of canopy conductance and tree transpiration is linked t

Background and aims: Measurement of grapevine size is necessary to assess carbon reserves at the level of individual vines and to estimate the carbon sequestration potential of vineyards. Methods of measurement rely mostly on traditional dendrological techniques that may be prone to error. In this study, we examined the use of structure-from-motion with multiview stereophotogrammetry (SfM-MVS) to obtain accurate measurements of vine trunk thickness and volume. SfM-MVS enables the creation of scaled, georeferenced three-dimensional models based on a set of overlapping photographs.Methods and re

AbstractForest dynamics are undergoing profound alteration due to the fact that climate change is increasing the frequency and severity of abiotic and biotic forest disturbances. Because of the unpredictable nature of the drought periods and the variation in their severity, Mediterranean forests are typically more vulnerable. Mediterranean Pinus pinaster forests are showing decay symptoms linked to climate change. There is clear evidence that promoting mixtures can serve as an effective forest adaptation strategy. In this regard, we sought to better understand the responses of P. pinaster radi

Abstract Mixed-species forests are, for multiple reasons, promising options for forest management in Central Europe. However, the extent to which interspecific competition affects tree hydrological processes is not clear. High-resolution dendrometers capture sub-daily variations in stem diameter; they can simultaneously monitor stem growth (irreversible changes in diameter) and water status (reversible changes) of individual trees. Using the information on water status, we aimed to assess potential effects of tree species mixture, expressed as local neighborhood identity, on night-time rehydra

Abstract Measuring and modelling the shape of tree stems is a fundamental component of forest inventory systems for both commercial and biological purposes. The change in diameter of the stem along its length (a.k.a. 'taper') is one of the most important and widely used means of predicting tree stem volume. Until recently, the options for obtaining accurate estimates of stem taper and developing stem taper models have been limited to measurements of felled trees or the use of optical dendrometers on standing live trees. Here, we tested both a tripod-mounted terrestrial laser scanner (TLS; a Fo

ECOSENSE is a Collaborative Research Centre (CRC) funded by the German Research Foundation DFG to develop and test novel environmental sensing techniques and apply them to enhance our understanding and modelling of water and carbon fluxes in forest ecosystems. Specifically, with a distributed sampling approach, ECOSENSE studies the impact of forest heterogeneity in space and time in response to hydro-climatic stresses (Werner et al. 2024). Core to the project is the ECOSENSE forest, located in the foothills of the Black Forest in Germany (48.2685 N, 7.8782 E). The forest primarily consists of
