Appendix G. A figure showing the variability in timing of white spruce regeneration between stands within fires.

Appendix E. Figures showing the age structures for trees in 1961, 1942, and 1941 fires, and one of the master chronologies used for crossdating.
 
   FIG. G1. Variability in timing of white spruce regeneration between stands within fires. Fires occurred with a 1-, 2-, or 3-year delay before the 1983 mast year (1982, 1981, and 1980, respectively). The first mast cohort (C) established 1 year after the mast year, and is shown in all figures. The n values denote the number of trees per stand. Different superscript letters denote stands within fires that had significantly different age distributions. Only one pairwise comparison was different (P < 0.05) for each of two fires (b1 and b4, and c4 and c6); consequently, Z-statistics are reported for these pairs (two-sided Kolmogorov Smirnov tests were used and P is Bonferroni corrected).
