Extended Data Fig. 6: Comparison of regeneration variables between overwintering (O) and single season (S) fires in the Northwest Territories (NT) and Alaska (AK).
From: Overwintering fires can occur in both peatlands and upland forests with varying ecological impacts
Boxplots showing distribution of regeneration variables including seedling density (seedlings m−2), basal diameter (m2 ha−1), and relative abundance of conifers (proportion conifer; unitless). Samples sizes for all of these variables were as follows: NT, n = 75 (9 overwintering and 6 single season fire sites with 5 nested plots per site] and AK, n = 66 (7 overwintering and 4 single season fires sites with 6 nested plots per site). In the fourth panel, Time indicates whether the proportion conifer value is for pre-fire (before) or post-fire (after). In this plot site-level means were used as the pre-fire composition is at the site level meaning n = 15 for NT and n = 11 for AK. Plots include median, 1st and 3rd data quartiles and outliers. Model results are presented in Supplementary Table 2.
