Mineral seedbed and slash consumption assessments weren't documented after the burn.
Regeneration, as measured in Summer 2016:
111 jack pine regenerants per acre; (<1” dbh and under 1’ tall)
2,165 seedlings per acre; (<1” dbh & over 1’ tall); 12% jack pine, 18% balsam poplar, 70% quaking aspen
55 jack pine saplings per acre; (1-3” dbh)
Intense competition with alder, beaked hazel, red raspberry, juneberry, willow, and choke cherry.
Jack pine regeneration was concentrated near the south and north ends of the stand. Lowbush blueberry (Vaccinium angustifolium) occurred in the 1 meter subplot of the species/area plot, indicating it is present at a fine scale. Wintergreen (Gaultheria procumbens) and round-leaved shinleaf (Pyrola rotundifolia) occurred in the 32 meter subplot (moderately fine scale). Bearberry (Arctostaphylos uva-ursi) occurred in the 1024 meter subplot, indicating it is present at a coarse scale.
443 regenerants per acre; 12% jack pine, 88% balsam fir
1,942 seedlings per acre; 74% jack pine, 14% balsam poplar, 8% balsam fir, 4% black spruce
443 saplings per acre; 75% jack pine, 12.5% balsam fir, 12.5% balsam poplar
Lowbush blueberry occurred in the 1 meter subplot (similar to the burned plot). Wintergreen occurred in the 16 meter plot (a bit finer scale than on the burned plot). We found no pyrolas or bearberry.
Some competition with beaked hazel, willow, and red raspberry
Total jack pine density on the burned plot was 425/ac. Total jack pine density on the unburned plot was 1822/ac.
We tallied 60 species on the species/area plot for the burned plot. That's 12 fewer species than on the unburned species/area plot. Thirty-two species that were present on the unburned plot were missing from the burned plot. Five of those species are non-native. Twenty species were found on both plots, but at a coarser scale on the burned plot, suggesting a lower density. Seven species were found on both plots at the same scale. Fifteen species occur at a finer scale in the burned plot than in the unburned. None of those were among the target species (blueberry or ericaceous shrubs). Nineteen species appeared in the burned plot that weren't in the unburned plot, including bearberry (a target species).
*Minimal aspen regeneration occurred on the unburned site, but not within our plots. Aspen regeneration was concentrated around two regeneration plots on the burned site. Scattered red pines exist on both sites, but not in our plots.
