“…Therefore we conducted the response-function analysis only for the present year that supported the results of correlation analysis by identifying the precipitation, the SPEI and the REW of June as the most significant (Figure 8). In general, our results correspond to other studies describing spring/summer moisture availability as the main climatic driver of Pinus nigra growth in the Mediterranean [65][66][67][68][69][70][71][72].…”

“…This may have exceeded the ability of trees to tolerate water shortages and triggered a mass mortality of Black pine in the study area by a (secondary) fungal pathogen attack [22]. Similar abrupt mortality of pines has been described by several authors [66,70,73] where droughts in combination with unfavourable site conditions initiated mortality episodes through additional stressors such as defoliation by fungal pathogens. The values of recovery and relative resilience dropped again from the values of the period 2000-2003 implying that the further decline in growth could be the superimposed effect of previous droughts (Figure 11).…”

This paper analyses the recent recurring dieback and growth decline of Black pine (P. nigra Arn. var austriaca) in the Keszthely mountains of south-west Hungary, and their relations to water deficits due to droughts. These relations were studied in five stands with low soil water storage capacity for the period 1981-2016. The vitality was assessed using 60 tree-ring samples and changes in remotely sensed vegetation activity indices, i.e., the normalized difference vegetation index (NDVI) and the normalized difference infrared index (NDII). Water deficit was estimated by using meteorological drought indices such the standardized precipitation-evapotranspiration index (SPEI) and the forestry aridity index (FAI), as well as the relative extractable water (REW), calculated by the Brook90 hydrological model. Results revealed a strong dependency of annual tree ring width on the amount of water deficit as measured by all the above estimators, with the highest correlation shown by the summer REW. Droughts also showed a long-term superimposed effect on tree growth. NDII seemed to be more sensitive to drought conditions than NDVI. The robust dependency of tree growth on the summer water availability combined with the projected increasing aridity might lead to decreasing growth of Black pine in Hungary towards the end of the century. We thus argue that the suggestion by several papers that Black pine can be a possible substitute species in the Alpine and Mediterranean region in the future should be revisited.

“…Our analyses agree with previous studies on drought-induced mortality, indicating that climate-growth responses to climate depend on previous tree growth since declining trees show lower growth rates [4,53], although other studies have shown higher growth rates for declining or recently-dead trees prior to drought occurrence [18,28,54]. Low growth rates were caused by warming-induced drought stress; specifically, water deficit in spring, as documented in other Iberian pine forests [15].…”

Abstract:The assessment of the long-term impacts of drought on tree growth decline using tree-ring analyses may be used to test if plantations are more vulnerable to warming after successive droughts, leading to a "cumulative stress" effect. We selected 76 Pinus pinaster trees (declining and non-declining trees), and basal area increments over the last 20 years (BAI 20 ) were calculated to build the chronologies for the stand types and vigor classes. Resistance, recovery and resilience indices were calculated. Pearson correlations, analyses and Partial Least-Squares regression were used to analyze the relationships among the response and environmental variables. We found a negative and significant relationship between mean temperature for May and June of the current year and growth in the naturally regenerated stands. This negative effect on growth under warm spring conditions was more noticeable in plantations than in naturally regenerated stands. A negative trend along time was found for the resilience index in planted stands. Evapotranspiration, maximum temperature and annual radiation showed significant and negative correlations with the growth of declining trees from planted stands, indicating they are susceptible to drought stress. Declining trees in planted stands showed a loss of growth resilience, specifically a negative trend after successive droughts.

“…Low rainfall in summer is often a factor limiting the incremental growth of Scots pine basically throughout all of its range (Lührte, 1991;Lindholm et al, 1997;Irvine et al, 1998;Cinnirella et al, 2002;Wilczyński and Skrzyszewski, 2003;Pensa et al, 2005;Tuovinen, 2005;Pilcher and Oberhuber, 2007;Piovesan et al, 2008;Gruber et al, 2010;Juknys et al, 2014). Drought is a factor which often induces variability in growth patterns and mortality of Scots pine especially in dry areas (Bigler et al, 2006, Hereş et al, 2012, Herguido et al, 2016, Marqués et al, 2016. Heavy rainfall during the growing season and, consequently, increased air humidity enhances the flow of water into the cells increasing the pressure on the cell wall, thus stretching these and causing cambium cell growth and it also provides the substrates for the process of photosynthesis (Major and Johnsen, 2001).…”

Abstract:The main aims of these studies were dendrochronological and mass spectrometric analysis of the impact of climate on tree rings width and stable isotopes composition in pine (Pinus sylvestris L.). The conifers were growing in the vicinity of chemical and nitrogen factories in Kędzierzyn-Koźle (Poland) in the period of time from 1920s to 2012 AD. The combined usage of tree ring width and isotopic composition data provides historic records of the environment changes. These data allows identifying the behavior adaptation of pine growing under pollution stress to climate changes. The incremental rhythm of the studied pine populations was not identical, probably due to their different sensitivities to some climatic factors. This study evidences that the isotopic records in tree-rings α-cellulose may be sensitive bio-indicators of the way that the components of air and water may be changed by the trees in response to the climate changes and anthropogenic effects. The water use efficiency may be strongly correlated with variability of the surface temperature that may be due to increase of CO 2 emission.
