Forest regeneration standards: are they limiting management options for Alberta's boreal mixedwoods?
Bibliographic record
Abstract
Regeneration standards in Alberta have developed incrementally over the last 40 years to ensure that cutover areas are regenerated with commercially valuable species that will contribute to timber yield. These standards have been controversial for the boreal mixedwood forest, because they do not appear to be producing forests that are similar in composition and structure to those found naturally. In this paper we discuss several components of the standards that are problematic: the issue of landbase designations that force relatively pure stands of spruce onto the landscape early in stand development compared to natural conditions where spruce establishes below deciduous canopies; the need for the free-to-grow standard, which requires removal of a large proportion of the deciduous trees in these mixedwood forests; and the overall philosophy that stands should be managed to maintain relatively simple composition and canopy structures. Regeneration standards need to be better-linked with forest management planning to allow managers to produce stands of a range of composition and structure. Key words: policy, free-to-grow, competition, forest composition, succession

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.
