- Average values are presented for DBH diameter breast height, height tree height, TRW tree-ring width, segment length number of measured tree rings per tree. Values between parentheses denote standard deviations. glk Gleichläufigkeit, RBAR inter-series correlation, MS mean sensitivity, AC first-order autocorrelation, EPS expressed-population signal. Statistics of tree-ring indices are presented for a 30-year period before and after resin extraction (before/after; see for periods Fig. 2)
