Selected dendrochronological statistics_ MTRW (mean tree-ring width), MRI (mean relative radial increment), and MCI (mean change of index) were calculated for 3 periods: (a) before reduction, (b) during reduction, (c) during recovery; rbt – the mean between-tree series correlation, EPS – the expressed population signal is a statistic for examining the common variability in chronology; rbt and EPS were calculated for 2 periods of time: (d) 1940–2012 (total common period, n=73) and (e) 1962–1989 (common reduction period, n=28)
