“…Similar results showing the positive effect of July temperatures on spruce growth were also seen in subalpine spruce forests of the Western Carpathians (Bednarz et al 1997), in northern expositions of the Elbe valley in the Krkonoše Mts. (Sander et al 1995) and in the Polish Tatras (Feliksik 1972). The positive influence of precipitation in July of the previous year was also found at lower altitudes of the Krušné hory Mts.…”

Research on the influence of temperatures and precipitation on radial increment was carried out in spruce stands over ninety years old in the surroundings of Anenský vrch in the Orlické hory Mts. at altitudes over 800 m above sea level. To model diameter increment in dependence on climatic conditions, the standard tree-ring and correlation analysis together with the analysis of negative pointer years were used. The diameter increment has a statistically significant correlation with temperatures in July of each year in question. The growth of spruce is also affected to a statistically significant degree by precipitation in July of the previous year and by precipitation in February and March of the year in question. The standard tree-ring chronology shows an obvious decrease in radial increments starting at the beginning of the 1970s and ending at the end of the 1980s. The lowest increments were recorded for 1974, 1980, 1984 and 1986. These years with low increments were also confirmed by the analysis of negative pointer years. In the following period there is an increase in increments, with slight decreases in 1996 and 2000, which, however, according to the analysis of negative pointer years do not demonstrate any significant reduction of increments. Another decrease was recorded starting in 2003 and this lasted until the studied period, i.e. 2007. The current condition of spruce stands is certainly the result of more stressors but it appears that with the current air pollution load the climatic conditions are the factor determining the resulting effect of the synergic influence of the stressors on the stands.

-This paper explores the growth/climate relationships in earlywood, latewood and total ring-width chronologies of five Norway spruce (Picea abies) and six silver fir (Abies alba) stands sampled in the French permanent plot network (RENECOFOR) (327 trees). The relationships between climate and ring widths were analyzed using extreme growth years, simple correlations and response functions analysis (bootstrapped coefficients). Monthly climatic regressors were derived by a physiological water balance model that used daily climatic data and stand parameters to estimate soil water deficits. Pointer years underline the high sensitivity to winter frosts (1956, 1986) and exceptional annual droughts (1962, 1976, 1991) for both species. For those years, growth variations were higher for Abies alba than for Picea abies. For each species, the climate information of tree ring series is not modified by local site characteristics (altitude, slope, aspect, soil water reserve). Moreover, strong specific differences appear among species. Earlywood and latewood spruce growth mainly depends on current summer soil water deficit conditions. For silver fir, winter and early summer temperatures, as well as the water supply of the previous year (August to October) play a major role for the production of earlywood, after which the current early summer water supply influences mainly latewood width.Abies alba / Picea abies / tree ring / water balance / drought / pointer years / response functions Résumé -Réponse au climat du sapin pectiné (Abies alba Mill.) et de l'épicéa commun (Picea abies Karst.) dans le Réseau National de suivi à long terme des Écosystèmes Forestiers (RENECOFOR). Cet article présente les relations entre le climat et les variations des largeurs du bois initial, du bois final et du cerne complet pour cinq peuplements d'épicéa commun (Picea abies) et six peuplements de sapin pectiné (Abies alba) échantillonnés dans le réseau national de suivi à long terme des écosystèmes forestiers (RENECOFOR) (327 arbres). L'effet du climat sur la largeur des cernes a été analysé à partir de l'étude des années caractéristiques et l'établissement des fonctions de réponse. Les régresseurs climatiques mensuels pris en compte sont issus d'un modèle de bilan hydrique à base écophysiologique qui utilise comme variables d'entrée des données météorologiques journalières et les caractéristiques du peuplement. Les années caractéristiques montrent la forte sensibilité aux froids extrêmes (1956, 1986) et aux sécheresses intenses (1962, 1976, 1991) des deux espèces avec néanmoins des variations de croissance plus marquées pour le sapin pectiné. Pour chaque espèce, les caractéristiques écologiques locales (altitude, pente, exposition, etc.) ne modifient pas la réponse au climat. Cependant, le comportement des deux espèces apparaît très différent. Pour l'épicéa, la mise en place du bois initial et du bois final dépend essentiellement du déficit hydrique estival de l'année en cours. Pour le sapin, la largeur du bois initial dépend à la fois...

“…They are often connected with a combination of influences resulting from extremely dry years (such as 1948, 1956 and 1976) and from air pollution, mainly NO x , SO 2 and ozone (Bert 1993). These non-climatic environmental changes will, at the very least, obscure the climatic signal in treerings and hamper significantly the task of reconstruction (Sander et al 1995). Although longer continuous measurements of such pollutants for the southern Moravian region are not available, important increases in their concentrations are known to have occurred over a large part of the Czech Republic between the 1960s and 1980s (Materna 1989).…”

A ring-width chronology for fir Abies alba Mill. in southern Moravia (Czech Republic), compiled from historical wood and living trees, was used for the dendroclimatological reconstruction of March-July precipitation for the period 1376-1996. Based on a response function model, the precipitation series explains 38% of tree-ring width variability. In the years with thinner tree-rings, drier spring and summer seasons prevailed, whereas years with wider tree-rings indicate wetter conditions. The highest precipitation in the reconstructed series was found in the 1670s, 1710s and 1980s; the lowest in the 1380s, 1700s and, particularly, in the 1970s. Reconstruction after the 1950s is less reliable due to a weaker relationship between precipitation and fir growth. The 18th century was the driest and the 19th century the wettest in the last 600 yr. The comparison of the reconstructed March-July precipitation of southern Moravia with the Brno series (instrumental period) and with the Prague-Klementinum series (compiled from the quantitative interpretation of documentary evidence and instrumental measurements) shows a high degree of agreement, reflecting the similarities between these series over the instrumental period. During the 16th, 17th and 18th centuries the 2 proxy data sources -documentaries and tree-rings -are in satisfactory agreement with respect to those years with extremely thin or wide rings.

In some cases the numbers of precipitation days have also been interpreted (Woodhouse & Meko 1997). Tree-ring chronologies from North America and Europe have also been used for the reconstruction of the North Atlantic Oscillation (Cook et al. 1998). In the construction of long tree-ring chronologies, dendrochronologists must work with unusually long-lived trees or they must extend the records obtained from living trees by piecing together or overlapping records from sources of ancient wood, such as archaeological, historical or naturally preserved (subfossil) remnants (Briffa 2000).In the Czech Republic dendroclimatological reconstructions have so far been paid only little attention, largely because of the absence of a suitable tree-ring series. Currently only the relationship between climatic characteristics and the radial growth of trees has been analysed (such as Sander 1991, Sander et al. 1995.
