Abstract

fetched live from OpenAlex

Abstract For partially harvested stands in the British Columbia interior, we present a new method for specifying regeneration stocking standards and a procedure for comparing achieved regeneration to the standard. Understory stocking is assessed in terms of the deviation from potential yield that the observed understory tree density represents. For a harvested area, the minimum stocking standard is stated as the maximum allowable mean deviation from potential. Deviation from potential is expressed on a relative (0–1) scale and predicted from overstory basal area and understory tree density. Because of a scarcity of calibration data, we undertook a crude, preliminary calibration of this relationship. As overstory basal area increases, the understory density required to achieve a given degree of understory stocking decreases. Issues pertaining to the stand management context and other approaches to regulating regeneration also are discussed. West. J. Appl. For. 20(1):5–12.

Not 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.
