“…Tree rings associated to climate provide information about the average relationship between climate and tree growth. However, climatic forcing of a single extreme year in a tree ring series is not revealed for statistical reasons [26,27], and a suitable approach is to compare extreme growth events with instrumental data [69]. Another limit of using tree rings is that the retrospective analysis of tree growth may lead to underestimate the impact of extreme events, especially in managed forests.…”

The aim of this paper is to illustrate how some extreme events could affect forest ecosystems. Forest tree response can be analysed using dendroecological methods, as tree-ring widths are strongly controlled by climatic or biotic events. Years with such events induce similar tree responses and are called pointer years. They can result from extreme climatic events like frost, a heat wave, spring water logging, drought or insect damage. . . Forest tree species showed contrasting responses to climatic hazards, depending on their sensitivity to water shortage or temperature hardening, as illustrated from our dendrochronological database. For foresters, a drought or a pest disease is an extreme event if visible and durable symptoms are induced (leaf discolouration, leaf loss, perennial organs mortality, tree dieback and mortality). These symptoms here are shown, lagging one or several years behind a climatic or biotic event, from forest decline cases in progress since the 2003 drought or attributed to previous severe droughts or defoliations in France. Tree growth or vitality recovery is illustrated, and the functional interpretation of the long lasting memory of trees is discussed. A coupled approach linking dendrochronology and ecophysiology helps in discussing vulnerability of forest stands, and suggests management advices in order to mitigate extreme drought and cope with selective mortality.

“…The classic book 'Tree Rings and Climate' by Fritts (1976) provided a superb introduction to the science of dendrochronology and an in-depth description of techniques useful for extracting climatic information from tree-rings. More recently a complete overview of the 'Methods of Dendrochronology and the Applications in the Environmental Sciences' is edited by Cook & Kairiukstis (1990) with excellent contributions of for instance Guiot (1990), Visser & Molenaar (1990), Eckstein (1990) , ... Such procedures of the black box type have proved to be useful in a number of pattern-recognition tasks, but the knowledge they acquire tends to be rather opaque.…”

(1) Tree-rings are a challenge for modern ecological research dealing with 'time' and 'complexity'. (2) Machine learning appears to be an efficient tool to extract knowledge from data sets showing a high degree of complexity. (3) The software package PC/BEAGLE, using the evolutionary learning algorithm, is able to find some high quality rules for Nelder design poplar plantations. (4) Poplar trees growing in thin stands show a strong negative temperature signal. (5) 'Beaupré' trees are almost always more massive than 'Unal' trees, except for the first years after planting in the wider planting distances.

A novel methodological framework is presented for climate-sensitive modeling of annual radial stem increment using year-ring width time series. The approach is based on a generalized additive model with penalized regression splines together with a distributed time lag model taking into account smooth nonlinear effects of a series of monthly temperature and precipitation values, as well as their interactions. Climate effects are also assumed to vary smoothly with time lag. The model framework enables both the detrending of the individual time series and the regression modeling to be performed simultaneously in a single model step. The approach is applied to year-ring width time series of Norway spruce (Picea abies (L.) H. Karst.) trees in Tyrol, Austria. The marginal response curves show that tree growth is mainly promoted by high temperatures in late spring and early summer and by precipitation in fall and winter. Summer drought does not have a negative influence on the current year’s radial increment; however, when it is associated with high temperatures, it lowers the increment in the subsequent growth period. Higher winter precipitation in conjunction with lower temperatures has a positive effect. A significant non-climate related long-term growth trend is demonstrated, probably reflecting NOx and SO2 emission trends in Austria.
