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

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
