Climate model projections suggest widespread drying in the Mediterranean Basin and wetting Fennoscandia coming decades largely as a consequence of greenhouse gas forcing climate. To place these other "Old World" climate into historical perspective based on more complete estimates natural hydroclimatic variability, we have developed World Drought Atlas" (OWDA), set year-to-year maps tree-ring reconstructed summer wetness dryness over Europe during Common Era. The OWDA matches accounts severe...
Abstract Aim Primary forests have high conservation value but are rare in Europe due to historic land use. Yet many primary forest patches remain unmapped, and it is unclear what extent they effectively protected. Our aim was (1) compile the most comprehensive European‐scale map of currently known forests, (2) analyse spatial determinants characterizing their location (3) locate areas where so far unmapped likely occur. Location Europe. Methods We aggregated data from a literature review,...
Aim To evaluate the climate sensitivity of model-based forest productivity estimates using a continental-scale tree-ring network. Location Europe and North Africa (30–70° N, 10° W–40° E). Methods We compiled close to 1000 annually resolved records radial tree growth for all major European species quantified changes in as function historical climatic variation. Sites were grouped neural network clustering technique isolate spatiotemporal species-specific response patterns. The resulting...
Abstract Aims Primary forests are critical for forest biodiversity and provide key ecosystem services. In Europe, these particularly scarce it is unclear whether they sufficiently protected. Here we aim to: (a) understand extant primary representative of the range naturally occurring types, (b) identify types which host enough under strict protection to meet conservation targets (c) highlight areas where restoration needed feasible. Location Europe. Methods We combined a unique geodatabase...
Abstract Primary forests, defined here as forests where the signs of human impacts, if any, are strongly blurred due to decades without forest management, scarce in Europe and continue disappear. Despite these losses, we know little about occur. Here, present a comprehensive geodatabase map Europe’s known primary forests. Our harmonizes 48 different, mostly field-based datasets contains 18,411 individual patches (41.1 Mha) spread across 33 countries. When available, provide information on...
Abstract Recent observations of tree regeneration failures following large and severe disturbances, particularly under warm dry conditions, have raised concerns about the resilience forest ecosystems their recovery dynamics in face climate change. We investigated temperate forests Europe after disturbance events (i.e., resulting more than 70% canopy loss patches larger 1 ha), with a range one to five decades since occurred. The study included 143 sites different types management practices...
Abstract Carbon accounting in the land sector requires a reference level from which to calculate past losses of carbon and potential for gains using stock-based target. carrying capacity represented by stock primary forests is an ecologically-based that allows estimation mitigation derived protecting restoring increase their stocks. Here we measured collated tree inventory data at forest sites including research studies, literature inventories (7982 sites, 288,262 trees, 27 countries) across...
The jet stream is an important dynamic driver of climate variability in the Northern Hemisphere mid-latitudes
The dominant atmospheric circulation pattern that governs European summer climate is a blocking-like over the British Isles co-occurs with low southeastern Europe. meridionally oriented configuration of this favours intrusion warm air northeastern Mediterranean during one mode and northwestern Europe its opposite mode. We present temperature reconstruction (1768–2008) for node teleconnection pattern. This based on maximum latewood density (MXD) measurements 23 Pinus heldreichii trees from...
ABSTRACT With ongoing global warming, increasing water deficits promote physiological stress on forest ecosystems with negative impacts tree growth, vitality, and survival. How individual species will react to increased drought is therefore a key research question address for carbon accounting the development of climate change mitigation strategies. Recent tree‐ring studies have shown that trees at higher latitudes benefit from warmer temperatures, yet this likely highly species‐dependent...
Abstract The mechanistic pathways connecting ocean-atmosphere variability and terrestrial productivity are well-established theoretically, but remain challenging to quantify empirically. Such quantification will greatly improve the assessment prediction of changes in carbon sequestration response dynamically induced climatic extremes. jet stream latitude (JSL) over North Atlantic-European domain provides a synthetic robust physical framework that integrates climate not accounted for by...
The European Mediterranean region is governed by a characteristic climate of summer drought that likely to increase in duration and intensity under predicted change. However, large-scale network analyses investigating spatial aspects pre-instrumental variability for this biogeographic zone are still scarce. In study we introduce 54 mid- high-elevation tree-ring width (TRW) chronologies comprising 2186 individual series from pine trees (Pinus spp.). This compilation spans 4000-km east–west...
Abstract Aims We examined differences in life span among the dominant tree species (spruce, Picea abies ; fir, Abies alba beech, Fagus sylvatica and maple, Acer pseudoplatanus ) across primary mountain forests of Europe. asked how disturbance history, lifetime growth patterns, environmental factors influence span. Locations Balkan Mountains, Carpathian Dinaric Mountains. Methods Annual ring widths from 20,600 cores were used to estimate spans, trends, history metrics. Mixed models examine...
The effective biodiversity goal achievement presupposes cross-sectoral policy coherence and implementation across EU, national local levels. also depends on supportive behavioural responses by forest owners managers who have to respond multiple socio-economic drivers forcing them make trade-offs under uncertainty. This research is a continuation of previous which suggests that conflicts failures understand constitute major barriers achieving desired outcomes. results these survey for...
ABSTRACT Aim Norway spruce ( Picea abies ) is a dominant tree species across Eurasia, and known to regenerate on decaying logs. Understanding its regeneration dynamics crucial for predicting forest sustainability under climate change. The decay type of the logs, indicative fungal capabilities lignin holocellulose traditionally categorised into white rot brown rot, markedly influences seedling density because reduces their establishment. As distribution wood types are affected by...
Natural disturbances are among the most important factors that shape forest dynamics and landscapes. However, natural disturbance regime of Norway spruce (Picea abies (L.) Karst.) forests in Europe is not well understood. We studied regimes three reserves Bulgaria (Parangalitsa, Bistrishko branishte, Beglika), which representative range conditions typical for P. ecosystems central southern Europe. Our data indicated large-scale were numerous between 120 160 years old, those with unimodal...
Norway spruce forests are among the most affected by natural disturbances in Europe. One of key aspects is regeneration disturbed areas, which decisive for later forest development. We studied after two windthrows that occurred 30 (1983) and 50 years ago (1962) an old-growth over 150-year-old Parangalitsa Reserve a recent windthrow (2001) 130-year-old single cohort Bistrishko branishte Bulgaria. set up study plots along transects, counted substrates, analyzed age using tree rings....
