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