“…Tree‐ring width chronologies offer an expedient way to examine how trees might respond to future changes in climate (Mann et al 2002, Smith and Lewis 2007) and numerous tree‐ring studies report important modifications to growth related to climate variation (Vicente 2001, Martinelli 2004, Luckman and Scott 2007, Lapointe‐Garant et al 2010). However, several factors should be considered when using tree‐ring studies to make inferences about climate influences on growth.…”

Tree-ring data have become widely used to model tree growth responses to climate variability and gain insight about the potential effects of global warming on forests. We capitalized on a rare opportunity to develop growth-climate models using tree-ring data collected from all trees (>4 cm in diameter at breast height) within 50 × 50 m plots established in subalpine old-growth forests of western Canada. Our objective was to determine how tree growth responses to climate vary among tree size classes, species, and sites. We modeled relationships between times series of annual basal area increment (ΔBA) and yearly climate variables for individual trees; this approach obviated key statistical criticisms of "traditional" tree-ring analysis methods. Time series of annual basal area increment were detrended a priori for size, age, legacy, and competition effects. We found that the overall climate signal in our time series of ΔBA was weak; <6% of the interannual variance was explained by climate variables. Nevertheless, there were clear patterns in climate-growth relationships related to tree size and species. Relationships between ΔBA and five climate variables increased in strength with tree size class; large trees were most sensitive to annual climate fluctuations and accounted for~71% of the overall climate effect on growth across all trees and sites. In all stands, ΔBA variance explained by climate variables was stable over the 20th century for large trees but decreased in the 1940s for small trees, indicating a temporal reduction in sensitivity to annual fluctuations in five climate variables. In coastal forests, relationships between ΔBA and climate for Callitropsis nootkatensis were significantly different in direction and magnitude than those of co-occurring Pinaceae species. The effect of climate on tree growth was idiosyncratic among stands and could not be discriminated by forest type (coastal vs. interior). Our individual-tree modeling approach adds to a growing body of research providing novel insights about the complexities of tree growth responses to climate variability and the challenges associated with predicting future tree growth and forest productivity using tree-ring data.

“…Dendrochronology is a well-established science initially proposed by Andrew Ellicott Douglass at the beginnings of the 20 th century and that provides estimates of both the annual growth of woody plants and other environmentally relevant information through the analysis of physical or chemical properties of tree-ring wood (Bannister, 1963; Coulthard and Smith, 2013; Fritts, 1976; Fritts et al, 1965; Shroder, 1976; Smith and Lewis, 2006). Tree-ring methods have been applied across many different disciplines, including archaeology, for example, dendroprovenancing (Cherubini, 2021; Cherubini et al, 2022; Domínguez-Delmás, 2020; Wilson et al, 2017), environmental reconstructions including hydroclimatic parameters, such as temperature (Aryal et al, 2020) and precipitation (Tejedor et al, 2020), streamflow (Akkemik et al, 2008), floods (Speer et al, 2019), droughts (He et al, 2018) and events such as snow avalanches (Laxton and Smith, 2009; Luckman, 2010; Yadav and Bhutiyani, 2013), landslides (Chalupová et al, 2020), forest fires (Brown et al, 2020), air pollution episodes (Ballikaya et al, 2022; McLaughlin et al, 2002), insect outbreaks (Büntgen et al, 2009) and fungal attacks (Cherubini et al, 2002, 2021).…”

Recent developments in tree-ring research offer great potential for reconstructing past climate changes; determining the frequencies of natural hazards; and assessing the availability of freshwater resources over timescales that extend well into the pre-instrumental period. Here, we review the state of dendrochronological research in the Himalaya and outline future directions for tree-ring-based hydrological reconstructions in a region that has a pressing societal need to understand the causes and consequences of past, present and future changes in the hydrological cycle. We used ‘tree ring’ and ‘Himalaya’ as keywords to identify scholarly articles from the Web of Science that were published between 1994 and 2022. The resulting 173 publications were separated by their spatial coverage into the western, central and eastern Himalaya, as well as their scientific purpose (e.g. reconstructing growth-climate relationships, temperature, precipitation, streamflow, floods, droughts, etc.). Our analysis shows that dendrochronological research in the Himalaya primarily focused on understanding growth-climate relationships using annual tree-ring widths measurements obtained for coniferous species, and their application in climate reconstructions. Reconstructions of hydrological processes such as streamflows, and extremes such as glacial and landslide lake outburst floods, have received less attention. Recent advances in dendrochronology, including blue intensity (BI), quantitative wood anatomy (QWA), and tree-ring stable isotopes (TRSI) should be combined to improve the resolution and accuracy of hydrological reconstructions in all parts of the Himalaya. Such studies may allow us to better understand the effects of climate change and the Himalayan water resources for its lowland surroundings. They may also facilitate decision-making processes for mitigating the impacts of climate change on natural hazards, and for better managing water resources in the region.

“…The dominant and co-dominant P. wallichiana trees having straight boles with large crowns and gnarled branches were sampled. In total, 30 trees (60 cores) were sampled at breast height using Swedish increment borers following the standard procedures of dendrochronology (Fritts, 1976;Smith & Lewis, 2006). For each tree, two 5 mm increment cores were obtained from opposite sides of the tree.…”

The impacts of global warming are pervasive across different forest biomes and are most pronounced in high mountain ecosystems such as the Himalayas. This study examines the growth response of Blue pine (Pinus wallichiana) to climate from Bumthang district in the central Bhutan Himalaya. Tree radial growth parameters (ring width index and basal area increment) were correlated with monthly and daily climate. Temporal changes in significant climate response were assessed using running correlations. Irrespective of tree growth parameters or temporal resolution of climatic variables, growth-climate response revealed maximum temperature during summer as the most significant climatic factor regulating the growth of P. wallichiana in central Bhutan. The strength and stability of the climate response improved when using daily climate, which is not restricted by non-biological calendar months. Around the turn of the 21st century, we observed a rapid rise in radial growth. Over the last ~30 years, blue pine from central Bhutan has benefited from warming summer season maximum temperatures. This study highlights the importance of considering daily climate variables for more accurate assessments of tree growth responses to climate. These findings have significant implications for understanding the impact of climate change on forests in the Himalayan region.
