Over the past several decades, afforestation efforts have significantly increased globally to compensate for the deficiencies of natural forest. It is critical to understand the sensitivity and resilience to extreme drought in planted and natural forests, which may provide valuable information for forest ecosystem management in sight of climate change. Chinese pine (<em>Pinus tabulaeformis</em>) is a widely planted tree species in northern China, strategies of its marginal forests to drought stress are important to explore their responses to past drought events and evaluate their potential to withstand future droughts. In this study, dendrochronological methods and structural equation modeling (SEM) were employed to analyze the differences in the driving mechanisms of drought resistance and recovery between the planted and the natural <em>P. tabulaeformis</em> forests in the warm temperate-subtropical climate transition zone of China. The results indicated the following: (1) Both the planted forest and the natural forest of <em>P. tabuliformis</em> exhibited low resistance (RT) but high recovery (RC), while the planted forest showed lower RT and higher RC compared to the natural forest; (2) Palmer Drought Severity Index (PDSI) was the dominant climatic factor, exerting similar positive effects on RT of the two forests but with contrasting effects on RC (significantly positive in planted forest yet negative in the natural forest); (3) Biotic factors, specifically the tree growth of the two preceding years (PreTRW) and tree age (AGE), also played critical roles by negatively influencing RT and RC in both forest types. (4) Compared to the natural forest, the higher drought risk in the planted forest was mainly attributed to its homogeneous age and similar individual structural characteristics (such as DBH and tree height), which underscored their greater vulnerability and limited their resistance under drought stress. These findings indicate that biotic and abiotic factors co-regulate the drought resilience of the planted and the natural <em>P. tabulaeformis</em> forests. This research provides useful references for afforestation planning and the preservation of natural forests under future climate change.</div></div>","PeriodicalId":50595,"journal":{"name":"Dendrochronologia","volume":"94 ","pages":"Article 126445"},"PeriodicalIF":2.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145617732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although numerous studies have examined this issue worldwide, comprehensive coverage of all global treelines remains impossible, and the roles of temperature and precipitation exhibit pronounced spatiotemporal variability. To address these gaps, we collected tree-ring samples from two <em>Picea</em> species at treeline sites in the Helan Mountains (western China) and Luya Mountain (central China) along the same latitude, and conducted dendroclimatic analyses. Correlation analyses revealed that in the Helan region, growing-season temperatures had a significant negative influence on tree growth before 1998, after which precipitation became the dominant positive driver. SPEI-based analyses showed significant positive correlations between ring width and multi-month SPEI from June to August, indicating that tree growth at the Helan treeline was moisture-limited. In contrast, tree growth at the Luya site was consistently and positively correlated with May temperature, with no significant relationship to precipitation. Analyses using SPEI further demonstrated that moisture is not a limiting factor for tree growth at the Luya treeline. Our findings suggest that macroclimate is likely governing how treeline trees respond to climate variability. Under continued warming, arid regions may experience growth decline due to intensified drought stress, whereas humid regions are likely to benefit from rising temperatures.

By developing tree-ring width chronologies and analyzing dendroclimatic relationships, we reveal spatially variable growth responses of valley-dwelling Siberian larch to climatic factors. Key findings include the following: (1) Significant spatial heterogeneity was observed in the sensitivity of radial growth to air temperature. In valleys with low moisture availability (XDG and SKE), elevated temperatures constrained larch growth. (2) In valleys with sufficient moisture (TLH and KEM), moderate warming during the growing season enhanced radial growth. Low winter temperatures imposed significant growth limitations across all study sites. Heavy precipitation events during the growing season suppressed radial growth in moisture-saturated soils (TLH and XDG), potentially due to root hypoxia and scouring. (3) Overall, climate change has substantially altered the dominant climatic controls and sensitivity trajectories of Siberian larch radial growth in river valleys.

Under constant stress from strong unidirectional winds, coniferous trees normally show asymmetric growth patterns via a shift of the geometric center. In this study, we found that variations of the tree-ring geometric center (TRGC) of <em>Pinus massoniana</em> were a good indicator of SWS changes from previous August to current May in the Poyang Lake area of southeastern China, where northerly winds are prevailing and strong before the arrival of the summer monsoon due to the effect of the narrow funnel topography.

This reconstruction revealed that the recent SWS decline in the 1970s, and then a reversal occurred in 2010. The reconstructed SWS exhibited a significant correlation with the Atlantic Multidecadal Oscillation (AMO) on the interdecadal scale. Furthermore, the AMO phase shifts may be important driving factors for the change of SWS in the Poyang Lake area.

Using tree-ring data and tree size parameters, we investigated age-girth-height relationships by developing linear and nonlinear regression models, and calculated treeline shifts based on age-altitude relationships of <em>Abies pindrow</em> (Himalayan Fir) over the last four centuries from the Daksum-Sinthan (DK-SN) and Gulmarg (GUL) sites of Kashmir, western Himalaya. The Fir tree reached its upper elevation limit of &gt;3500 masl by the mid-20^th century, with average shift rates over 360 years of ∼1.42 and 1.79 m/yr at GUL and DK-SN, respectively. The recorded highest shift-rate of Fir occurred during the 17^th century, coinciding with Little Ice Age climatic episode. Subsequent decline in shift-rates to &lt;1 m/yr, relate to low-moisture conditions during the pre-monsoon months (April-June) hampering seedling establishment.
