“…Although new geochronological methods increase the number of dated geohazards (e.g., landslides and debris flows), absolute dating methods (e.g., cosmic ray exposure, optically stimulated luminescence, thermoluminescence, and uranium-series ( 234 U/ 230 Th) dating) are still less developed for geohazards occurred on the centennial or millennial timescales (Crosta and Clague, 2009;Pánek, 2015). The dendrogeomorphic technique (tree ring-based) has been developed to constrain the ages of geohazards that were recorded as growth disturbances in tree rings on a centennial or millennial scale (Butler et al, 1986;Stoffel et al, 2005;Stoffel, 2006;Šilhán et al, 2016;Noguchi et al, 2021). Frequent geohazards impact local trees, leading to growth disturbances in tree rings (e.g., wider or narrower rings, and missing rings), which are used to determine the time and frequency of geohazards (Stoffel et al, 2005;Schneuwly and Stoffel, 2008;Lopez Saez et al, 2012;Šilhán, 2017;Zhang et al, 2019;Šilhán, 2021).…”

A rare study on the quantitative relationship between the energetic impact of debris flows on the intensity and duration of growth disturbances of tree rings was carried out, partly due to a lack of feasible approaches and detailed field evidence. In this study, we first used a dendrogeomorphic technique to determine the age of a recent debris flow derived from historic landslide deposits at Qingyang Mountain (QYM) on the northeastern Tibet plateau. We acquired the quantitative data on the annual widths of tree rings in history and confirmed the influence of the debris flow rather than other factors (e.g., climatic events and inset outbreaking) in disturbing the growth of tree rings in a specific year. Using this approach, we determined that the age of the debris flow at QYM occurred in 1982, which was speculated to be triggered by the high monthly precipitation registered during July 1982. Subsequently, based on the boundaries of historic debris flow identified on remote sensing images before and after 1982 and the depth-integrated continuum model, we reconstructed the process of the 1982 debris flow and obtained the kinematic energy of the debris flow impacting the sampled trees. Based on the study, we observed that two growth disturbance patterns of tree rings influenced by the reconstructed 1982 debris flow were revealed, including growth suppression and asymmetric growth. We obtained a raw logarithm relationship between duration (i.e., lasting time for the disturbed tree rings to recover the initial width) and intensity of growth disturbances (i.e., growth suppression ratio of disturbed tree rings). We concluded that there is a negative exponential relationship between the simulated kinematic energy of debris flow impacting the disturbed trees and the time to recover the initial width of corresponding tree rings.

Based on the study, we observed that two growth disturbance patterns of tree rings influenced by the reconstructed 1982-debris flow were revealed including growth suppression and asymmetric growth. A raw logarithm relationship between duration (i.e. lasting time for the disturbed tree rings to recover the initial width) and intensity of growth disturbances (i.e. growth suppression ratio of disturbed tree rings) was obtained.

“…In forestry, it has been used to further our understanding of biomass production, using annual radial tree growth as an indicator. Moreover, tree growth has also been used for reconstructing atmospheric variations in temperature (Lebourgeois 2000;Liang et al 2008 (Oddi and Ghermandi 2015) or landslides (Noguchi et al 2021;Šilhán 2021). Tree ring chronologies have become established as a reliable proxy re ecting biosphere-level changes.…”

Do trees on agrarian stone walls respond to contemporary climate warming?

Agrarian stone walls and associated landscapes are present in different parts of Central and Western Europe. Somewhere they are conserved as valuable components of cultural landscapes whereas elsewhere they do not have any formal conservation status. These stone walls and the habitats connected to them host many old trees, which are potential archives of environmental changes. In the available literature there are practically no studies looking at the archival value of trees on agrarian stone walls. In our study we investigated sycamore maples growing on stone walls in the Ore Mts region of Czechia. We focussed on annual wood growth using dendrochronological methods and carried out pointer year analyses to examine environment-growth relationships. Our main findings suggest moderately heterogeneous growth among individuals within sites but that there is a common environmental response apparent in overall site chronologies. We observed low inter-series correlations within sites but only a fair to moderate Gleichläufigkeit and express population signal among ring width series at most of the study sites. Generally, we revealed mostly significant positive correlations with precipitation and negative correlations with increasing temperatures over the last years. From climate correlations analysis and pointer year analysis we could clearly infer that (1) tree growth on agrarian stone walls at three out of four of our sites is significantly impacted by current climate change and that (2) these trees have a good ecological-archival value because they are sensitive to contemporary warming; they should therefore be identified to be given a relevant conservation status and management.
