A silvicultural systems perspective on changing Canadian forestry practices
Bibliographic record
Abstract
Canadian forestry practices are changing to meet evolving forest management objectives, and these changes are frequently accompanied by new terminology.We examine the interaction among changing objectives, changing practices, and terminology in three forest types across Canada. Altered silvicultural practices and systems can generally be described using traditional terminology, and applying new terminology may create confusion. The most notable developments in silvicultural practice involve timber harvests with greater levels of tree retention, and new terminology is being applied mainly to designate changed harvest patterns. Timber harvesting is a crucial silvicultural practice, but does not by itself constitute a silvicultural system. It is necessary to more thoroughly define long-term stand-level management objectives, and to delineate complete silvicultural systems that address these objectives. This will require better knowledge of the long-term effects of forestry practices, particularly those resulting in structurally complex stands. Key words: silvicultural systems, forestry practices, terminology, harvesting, Canada, structural retention

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.
