“…Decreasing trends in winter and pre-monsoon precipitation were observed, with increasing drought and rising temperatures in recent decades across western and northwestern Nepal [24,46]. Under severe drought conditions, high competition for moisture between neighboring trees will further exacerbate drought stress for tree growth [47][48][49][50]. As shown in a recent study, low winter and spring precipitation can cause a delay of the initiation of xylogenesis and contribute to the occurrence of the locally missing rings in years with extremely dry springs [51].…”

Chir pine (Pinus roxburghii Sarg.) is a common tree species with ecological and economic importance across the subtropical forests of the central Himalayas. However, little is known about its growth response to the recent warming and drying trends observed in this region. Here, we developed a 268-year-long ring-width chronology (1743-2010) from western Nepal to investigate its growth response to climate. Based on nearby available meteorological records, growth was positively correlated with winter (November to February; r = 0.39, p < 0.05) as well as March to April (r = 0.67, p < 0.001) precipitation. Growth also showed a strong positive correlation with the sum of precipitation from November of the previous year to April of the current year (r = 0.65, p < 0.001). In contrast, a negative relationship with the mean temperature in March to April (r = −0.48, p < 0.05) suggests the influence of warming-induced evapotranspiration on tree growth. Spring droughts lasting 4-6 months constrain Chir pine growth. These results are supported by the synchronization between droughts and very narrow or locally missing rings. Warming and drying tendencies during winter and spring will reduce forest growth and resilience and make Chir pine forests more vulnerable and at higher risk of growth decline and dieback.

“…In the last decades, increasing evidence suggests that tree response to the climate is modulated by several endogenous factors, such as the genotype [11], age [12], size [13], and sex [14], in addition to exogenous factors of abiotic [15] and biotic nature [16,17]. Thus, population-based approaches might miss part of the wide range of individual responses that exist within a stand [18], obliterating different sources of variability that could contribute to more adequate management policies, or simply provide a better prediction of the individual growth responses to climate.…”

“…In forests where asymmetric competition dominates, larger trees, that intercept a greater amount of resources, are more sensitive to climate, showing a higher growth-induced reduction in dry years [13,20,23]. At the same time, smaller and suppressed trees growing in highly competitive environments show a lower climatic signal [10,16]. Finally, growth responses to climate depend on species identity and the specific identity of the neighbourhood [29,30].…”

Understanding the vulnerability of individual trees to climate requires moving from population to individual level. This study evaluates individual tree response in a mixed forest by assessing how size and neighbourhood density modulated growth responses to climate among coexisting tree species. To understand the complete variation in growth responses to climate, it is necessary to consider intrapopulation variability. Trees respond as individual entities, and their response is modulated by their characteristics and neighbourhood context. To assess the individual climate sensitivity, all living Iberian birches, European beeches, and pedunculate oaks trees located in a temperate mixed forest were cored in four 40 m × 40 m plots. Standard ring-width chronologies were built at tree and species level for the 1977-2007 period. Chronologies were related to climatic variables (monthly precipitation, hailstorm and mean temperature, and summer (June-August) precipitation). Growth response to climate varied among species and individual trees. Differences in climate-growth relationship among species could be partially attributed to the different xylem anatomy, since secondary growth of ring-porous pedunculate oak (Quercus robur L.) was mainly dependent on the previous-winter climatic conditions (January temperature), while for the diffuse-porous Iberian birch (Betula celtiberica Rothm. and Vasc.) and European beech (Fagus sylvatica L.), spring temperature and summer precipitation were the major constraining factors of growth. Tree features and identity of neighbourhood modulated climatic response, especially for Iberian birch and pedunculate oak. Dominant trees in less crowded neighbourhoods responded more intensely to climate factors. Understanding the individual variability of growth responses to climate will provide more realistic predictions of forests response to climate change.

“…Water is the most limited resource for mixed fir-pine stands in southern Spain, and is predicted to become even scarcer in coming years. To overcome this problem, forest managers use thinning (of different intensity) to reduce tree competition for water within stands (Martín-Benito et al 2011;Del Campo et al 2014). When properly used, thinning reduces long-term stress by competition, but it also reduces the vulnerability of trees to extreme drought events Sánchez-Salguero et al 2012).…”

“…Adaptive management could enhance growing conditions, and thus alleviate water stress that constrains photosynthetic activity and growth (McDowell et al 2003). Besides improving the tree productivity, thinning has important effects on understory, fauna and soil nutrient cycle and ecology (Martín-Benito et al 2011). However, the advantages of thinning for growth may not be the same for trees of different species (Moreno-Fernández et al 2014), mainly due to different duration of the growing period (Camarero et al 2011).…”

Foresters frequently lack sufficient information about thinning intensity effects to optimize semi-natural forest management and their effects and interaction with climate are still poorly understood. In an Abies pinsapo-Pinus pinaster-Pinus sylvestris forest with three thinning intensities, a dendrochronologial approach was used to evaluate the short-term responses of basal area increment (BAI), carbon isotope (δ 13 C) and water use efficiency (iWUE) to thinning intensity and climate. Thinning generally increased BAI in all species, except for the heavy thinning in P. sylvestris. Across all the plots, thinning increased 13 C-derived water-use efficiency on average by 14.49% for A. pinsapo, 9.78% for P. sylvestris and 6.68% for P. pinaster, but through different ecophysiological mechanisms. Our findings provide a robust mean of predicting water use efficiency responses from three coniferous species exposed to different thinning strategies which have been modulated by climatic conditions over time.
