Natural regeneration of white spruce in aspen-dominated boreal mixedwoods following harvesting

Abstract: In some boreal forests sites, there are considerable amounts of natural regeneration of white spruce (Picea glauca (Moench) Voss) after logging, even without silvicultural treatments to encourage establishment. We assessed the factors controlling the amount of this regeneration 8-15 years postharvest on previously aspen-dominated (Populus tremuloides Michx.) boreal mixedwood sites. We surveyed 162 transects across 81 cutovers, exploring the effects of mast years, season of harvest, distribution of seed trees, … Show more

“…Post-harvest regeneration depends on multiple environmental factors including the availability of light, water, and soil nutrients, micro-climatic conditions, and seedbeds (Blanco et al, 2009;Martin-DeMoor et al, 2010). While light conditions alone clearly do not determine regeneration response following harvesting, they remain a key factor (e.g., Lapointe et al, 2006), and a factor that can be manipulated through silvicultural interventions (Lieffers et al, 1999).…”

“…Temperature and soil moisture directly influence the success of conifer regeneration. Unfavorable weather conditions (e.g., drought) would compromise the processes of germination and establishment of conifer species [36,54,58]. Hydric stress or excessive temperatures during germination and seedling development can adversely affect their survival and incur significant mortality that is likely to limit or inhibit regeneration.…”

“…Depending upon these regional differences, we hypothesize that coniferous regeneration will be more abundant in aspen stands located in the eastern boreal forest due to higher precipitation and, by extension, the longer fire cycle that dominates this part of the transect; conversely, aspen stands in the west, which experience lower precipitation and more frequent and large fires, should exhibit lower coniferous regeneration [35,36].…”

“…This is particularly true for boreal mixedwood sites in which broadleaf species (primarily trembling aspen (Populus tremuloides Michx.)) quickly dominate postharvest sites (but see Martin-DeMoor et al 2010).…”
