|In unsalvaged mountain pine beetle-killed stands, the release and growth of shade-tolerant advanced regeneration may provide an important reforestation pathway. Stands developing from advanced 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. The project conducted under this grant reviewed and synthesized relevant scientific literature to suggest some important differences between reforestation from advanced 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 was given to primary traits of advanced regeneration that may determine their successional and growth trends following MPB attack, including their species composition, their abundance and spatial distribution, their age-height relationships, and their overall health. The review concludes that effective management of advanced 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.|
