摘要

The operational forestry practices employed by Millar Western Forest Products Ltd. in the Upper and LowernFoothills of Alberta, Canada integrate a broad range of tools to plan, implement, and manage post-harvest site regenerationnof pure and mixedwood boreal forests. Following tree harvesting, mechanical site preparation is often used to improve micrositenconditions to promote conifer seedling establishment or natural regeneration. Chemical and mechanical site preparationnand stand tending control competing vascular weed species. To meet forest regeneration commitments, incorporatingnknowledge gained from forestry experimentation, long-term field data and iterative deterministic modelling into modifiednmanagement approaches is employed to formulate appropriate vegetation management strategies. These strategies considernand balance multiple biodiversity (e.g., habitat supply modelling), physical environmental (e.g., streamflow), and societaln(e.g., industrial fibre requirements) needs relative to a regenerated vegetation complex. From this experience and understanding,nthe Company developed a series of generic establishment regimes (GERs), which prescribe detailed silviculturalnactivities to achieve site-regenerated vegetation complexes in alignment with higher-level forest management planning. Annoutcome of the GER formulation was the development of corresponding plant community assembly diagrams (PCADs),nwhich describe vegetation complexity and permit calculation of total biomass relative to the time series of silvicultural activitiesnwithin each GER. In turn, these allow forest planners to model biological, physical, and societal factors, while takingninto consideration specific stand growth trajectories based on impacts of silvicultural activities on vegetation biomassnand species composition. The GERs and PCADs help formulate vegetation complexes over time and are used to guide thenbehaviour of a vegetation growth model used in conjunction with a hydrologic simulation model.
