-The extreme drought event that occurred in Western Europe during 2003 highlighted the need to understand the key processes that may allow trees and stands to overcome such severe water shortages. We therefore reviewed the current knowledge available about such processes. First, impact of drought on exchanges at soil-root and canopy-atmosphere interfaces are presented and illustrated with examples from water and CO 2 flux measurements. The decline in transpiration and water uptake and in net carbon assimilation due to stomatal closure has been quantified and modelled. The resulting models were used to compute water balance at stand level basing on the 2003 climate in nine European forest sites from the CARBOEUROPE network. Estimates of soil water deficit were produced and provided a quantitative index of soil water shortage and therefore of the intensity of drought stress experienced by trees during summer 2003. In a second section, we review the irreversible damage that could be imposed on water transfer within trees and particularly within xylem. A special attention was paid to the inter-specific variability of these properties among a wide range of tree species. The inter-specific diversity of hydraulic and stomatal responses to soil water deficit is also discussed as it might reflect a large diversity in traits potentially related to drought tolerance. Finally, tree decline and mortality due to recurrent or extreme drought events are discussed on the basis of a literature review and recent decline studies. The potential involvement of hydraulic dysfunctions or of deficits in carbon storage as causes for the observed long term (several years) decline of tree growth and development and for the onset of tree dieback is discussed. As an example, the starch content in stem tissues recorded at the end of the 2003's summer was used to predict crown conditions of oak trees during the following spring: low starch contents were correlated with large twig and branch decline in the crown of trees. drought / water balance / time lag effect / hydraulic properties / dieback Résumé -Arbres et peuplements forestiers tempérés soumis à sécheresse : une revue des réponses écophysiologiques, des processus d'adaptation et des conséquences à long terme. La sécheresse exceptionnelle de 2003 a été l'occasion de faire le point de nos connaissances sur les mécanismes écophysiologiques permettant aux arbres de traverser un tel évènement climatique extrême. L'analyse a été conduite à l'échelle de l'arbre et du peuplement, tandis que l'intensité de la sécheresse a été quantifiée à l'aide d'un calcul de bilan hydrique sur neuf sites forestiers européens contrastés du réseau CARBOEUROPE. Le rôle du couvert dans les échanges avec l'atmosphère est rappelé puis intégré dans l'analyse des réductions de bilan d'eau et de carbone en 2003 dus à la régulation stomatique. Les caractéristiques du complexe sol-racine, important à la fois pour l'accès à la ressource et à l'efficience de son absorption, constituent un des premiers traits d'ada...

Der Standortskarte können bodenphysikalische Parameter aus den Merkmalsspiegeln der forstlichen Lokalbodenformen (KOPP et al., unveröffentlicht, KOPP u.

Die Evaluierung dieser räumlich vorliegenden Bodeninformationen wurde anhand von punktuell vorliegenden Bodeninformationen der zweiten Bodenzustandserhebung im Wald (BZE II), der Bodendauerbeobachtungsflächen (BDF) und der Ökologischen Waldzustandskontrolle (ÖWK) in SachsenAnhalt durchgeführt.Der Vergleich zwischen den Bodeninformationen dieser forstlichen Umweltmessnetze mit der Standortskartierung ergab eine genauere und verzerrungsfreiere Schätzung der bodenphysikalischen Parameter als die Schätzung der vorläufigen Bodenkarte. Sand-(R² = 0,85), Schluff-(R² = 0,81) und Tongehalte (R² = 0,52) der Bodenprofile der forstlichen Umweltmessnetze wurden durch die flächenhaften Daten der Merkmalsspiegel gut wiedergegeben. Deutlich geringere Überein-stimmungen ergeben sich für den Skelettgehalt (R 2 = 0,44), sowie für die aus den Grundlagendaten ermittelten Kenngrößen, wie nutzbare Feldkapazität (R 2 = 0,23) und potenzielle Kationenaustauschkapazität (R 2 = 0,33).

From the forest site map the soil physical parameters can be determined using characteristic soil profiles (KOPP et al., unpublished, KOPP and JOCHHEIM 2002, SCHWANECKE 1993, SCHULZE 1998). The quality of this available spatial soil information was evaluated using punctual soil information from the second national soil inventory (BZE II), the long-term soil monitoring network (BDF) and the ecological forest monitoring network (ÖWK) in Saxony-Anhalt.The comparison of the soil information from these forest monitoring networks with the characteristic soil profiles from the forest site map revealed a more exact, distortion-free estimation of the soil physical parameters than the comparison with the preliminary soil map.

Climate reconstructions in temperate Europe have been widely based on oak species. However, other co‐occurring species, largely distributed in Europe, may be used for recording climate variability. In this paper, we documented the intertrees and interspecies variations over 1960–2007 of oxygen and carbon isotopic compositions in ring cellulose of Fagus sylvatica, Pinus sylvestris, and Quercus petraea co‐occurring in the Fontainebleau forest (France). Our results indicated that large levels of series replication (11 trees on average) were required to generate isotopic mean series representative of the populations. We calculated mean isotopic ratios higher in pine than in the deciduous species and hypothesized that these contrasts resulted from differences in stomatal conductance, phenology, and canopy structure and, for oxygen, also in water uptake depth and isotopic exchange rate. We found that δ18O and δ13C chronologies were significantly correlated to one another in the three species and responded primarily to air moisture and Tmax, which indicated that stomatal conductance was an important driver of changes in both types of records. We determined that the correlations were strong with the May to July climate variables in F. sylvatica and with the July and August ones in Q. petraea and P. sylvestris. We showed that the oxygen records were systematically more coherent than those of carbon. This study demonstrated that δ18O, and to a lesser extent δ13C, from the three different species are reliable proxies for reconstructing past hydroclimatic variations in Europe.
