Spruce tree radial stem growth responded strongly to the changing environment in Central Europe during the period,with amean tree ring width increase of 24 and 32% for the 40- and 60-year old trees, respectively. The indicative General LinearModel analysis identified CO2, precipitation during the vegetation season, spring air temperature (March–May) and N-deposition as the significant covariates of growth,with the latter including interactions with elevation zones. The regressionmodels explained 57% and 55% of the variability in the two tree ringwidth chronologies, respectively. Growth response to N-deposition showed the highest variability along the elevation gradient with growth stimulation/limitation at sites below/above 700 m. A strong sensitivity of stemgrowth to CO2was also indicated, suggesting that the effect of rising ambient CO2 concentration (direct or indirect by increased water use efficiency) should be considered in analyses of long-term growth together with climatic factors and N-deposition.
