“…The first comprises tree-ring width data from a dense network of 568 forests for 16 tree species [75]. The second includes a 1.1 km spatial resolution NDVI dataset that allows for detecting the growth and NDVI signal in each forest stand, reducing the interferences associated with the non-related vegetation cover [54]. Changes in vegetation due to adverse environmental conditions have been addressed in the scientific literature from different methodological perspectives.…”

“…The Normalized Difference Vegetation Index (NDVI) is widely-used to assess vegetation activity, with a good agreement with the photosynthetically-active radiation absorbed by vegetation [41,53]. Here, we employed NDVI data at 1.1 km resolution for the period 1981 to 2015 at a monthly time scale aggregation [54]. The original data were obtained from the National Oceanic and Atmospheric Administration (NOAA) polar orbiting satellites that used the Advanced Very High Resolution Radiometer (AVHRR) sensors to provide daily satellite images.…”

“…In order to obtain the final NDVI product, the original data were subjected to a series of data processing, including radiometric calibration [55,56], geometric and topographic corrections [57,58], cloud cover removal [59] to obtain semi-monthly composite images by maximum NDVI value (two images per month) [60]. A comprehensive explanation of this procedure is found in Vicente-Serrano et al [54].…”

Drought is one of the key natural hazards impacting net primary production and tree growth in forest ecosystems. Nonetheless, tree species show different responses to drought events, which make it difficult to adopt fixed tools for monitoring drought impacts under contrasting environmental and climatic conditions. In this study, we assess the response of forest growth and a satellite proxy of the net primary production (NPP) to drought in peninsular Spain and the Balearic Islands, a region characterized by complex climatological, topographical, and environmental characteristics. Herein, we employed three different indicators based on

“…We studied forest growth in peninsular Spain and the Balearic Islands in southwestern Europe ( Figure S1). We used a recently created database of tree-ring width measures from 567 forests of 16 tree species (nine gymnosperms and seven angiosperms) across their Spanish distribution (Table 1; Gazol et al, 2018;Vicente-Serrano et al, 2020). We compiled raw tree-ring width information following dendrochronological methods (Fritts, 2001) for 16,660 tree-ring width series.…”

1. The negative impacts of drought on forest growth and productivity last for several years generating legacies, although the factors that determine why such legacies vary across sites and tree species remain unclear. 2. We used an extensive network of tree-ring width (RWI, ring-width index) records of 16 tree species from 567 forests, and high-resolution climate and normalized difference vegetation index (NDVI) datasets across Spain during the common period 1982-2008 to test the hypothesis that climate conditions and growth features modulate legacy effects of drought on forests. Legacy effects of drought were calculated as the differences between detrended-only RWI and NDVI series (i.e. after removing long-term growth trends) and pre-whitened RWI and NDVI series predicted by a model including drought intensity. Superposed Epoch Analysis (SEA) was used to estimate whether legacy effects differed from random. Finally, legacy effects were related to water balance, growth persistence and variability, and tree species identity. 3. We found a widespread occurrence of drought legacy effects on both RWI and NDVI, but they were seldom significant. According to SEA, first-year drought legacies were negative and different from random in 9% and 5% of the RWI and

“…In this sense, tree rings are natural archives on how trees responded to past droughts (Fritts, 1976;Ogle et al, 2000). Moreover, combining tree ring growth with estimates of primary productivity and vegetation activity (e.g., Correa-Díaz et al, 2019;Vicente-Serrano et al, 2019) enhances our ability to upscale growth patterns from individuals or stands to regional scales (Babst et al, 2018;Gazol et al, 2018;Kannenberg et al, 2019). This information, combined with high-resolution climate data, improves our understanding on how forests respond to drought at different spatial scales and allow us to understand drought-driven forest mortality (Hartmann et al, 2018).…”

The increase in frequency and intensity of droughts due to climate change might threaten forests under stress levels causing dieback and mortality episodes. Thus, deciphering how tree species from within a region respond to drought along environmental gradients should help us to understand forest vulnerability to climate change. To enlighten contrasting drought responses of dominant tree species, we reconstructed vegetation activity using Normalized Difference Vegetation Index (NDVI) and radial growth using tree-ring width series. We studied six tree species, three angiosperms (Fagus sylvatica, Quercus humilis, and Quercus ilex) and three gymnosperms (Pinus sylvestris, Pinus nigra, and Pinus halepensis), inhabiting a Mediterranean region in north-eastern Spain. We investigated if reduced growth resilience and increased growth synchrony after successive droughts (1986, 1989, 2005, and 2012): (i) were related to cumulative drought stress and (ii) preceded forest dieback in dry sites as compared to wet sites. In 2016, dieback affected Q. ilex and P. sylvestris stands in dry sites showing lower growth rates and NDVI. No dieback symptoms were observed in other species from dry (P. nigra, P. halepensis) or wet (F. sylvatica, Q. humilis, P. sylvestris) sites. Hot and dry summer conditions constrained growth and reduced NDVI. During 2005, a severe drought affected all species, but growth drops were more marked in dry places. All species were able to recover after extreme droughts, albeit angiosperms displayed lower than expected values of growth after the 2012 drought. Growth synchrony was higher in dry sites than in wet sites, and the differences were higher after the 2005 drought. This study reveals that the sensitivity of tree species to drought in species inhabiting the same region is species dependent, and it is contingent on local conditions with higher effects in dry sites than in wet sites. We describe how a cumulative impact of successive droughts increases growth synchrony and triggers the occurrence of dieback events in Mediterranean forests.
