“…Shade-tolerant species should better utilize the gradual increases in light levels likely to follow mpb attack compared to shade-intolerant trees (Messier et al 1999;McCarthy 2001;Krasowski and Wang 2003). The residual shading of snags and live-canopy trees should limit the expansion of aggressive, non-tree vegetation (Lieffers and Stadt 1994;Ricard and Messier 1996;Krasowksi and Wang 2003;Kurulok and McDonald 2004), which could otherwise suppress advance regeneration after mpb disturbance (Bassman et al 1992;Stone and Wolfe 1996).…”

In unsalvaged stands killed by the mountain pine beetle, the release and growth of shade-tolerant advance regeneration may provide an important reforestation pathway. Stands developing from advance regeneration may restock quickly and provide short- to mid-term harvest opportunities, but the variability in release and growth responses among these stands will create numerous management challenges. This paper reviews and synthesizes relevant scientific literature to suggest some important differences between reforestation from advance regeneration following mountain pine beetle (MPB) attack and conventional reforestation (i.e., planting or natural reforestation following “normal” disturbance events) in regards to stand dynamics and growth. Particular attention is given to the primary traits of advance regeneration that may determine its successional and growth trends following mpb attack, including species composition, abundance and spatial distribution, developmental characteristics, and overall health. Effective management of advance regeneration following MPB attack will require a better understanding of the stand-level conditions and processes that control its growth. As well, management tools such as stocking standards that are suited to managing even-aged forests may need to be re-examined to address the unique conditions of unsalvaged MPB stands.

Saplings of canopy tree species frequently undergo alternating periods of suppression and release before reaching canopy size. In this study, we document the effects of periods of suppression and release on current responses to variation in light by saplings of the 11 major tree species of northwestern, interior British Columbia. We were specifically interested in the degree to which increasing length of suppression had long-term effects on subsequent response to release in gaps or following partial cutting, and the degree to which the effects of suppression were ameliorated with time following release. At least some saplings of all 11 species had undergone alternating periods of suppression and release. The most shade-tolerant species generally did not show either a decline in growth over time during suppression or a gradual increase in growth at a given light level over time during release. The least shade-tolerant species exhibited significant declines in growth rate during suppression; however, in all of the species except trembling aspen (Populus tremuloides Michx.), the effects of suppression disappeared over time during release. Failure to account for the effects of past suppression and release leads to significant overestimates of the initial responses of shade-intolerant species to release. Our results suggest that competitive balances between species shift substantially over time as a result of growth history and that these shifts have significant effects on successional patterns.
