Abstract
Using data from 41 plots, the diameter structure and composition of old-growth mixed stands composed mainly of balsam fir (Abies basalmea (L.) Mill.) and red spruce (Picea rubens Sarg.) were characterized. The stand table was organized in five groups of diameter classes, and we characterized the basal area of four tree species in each group. Analysis showed that diameter structure tends toward a reverse J-shaped curve. Red spruce and yellow birch (Betula alleghaniensis Britt.) were more abundant among large diameter trees while balsam fir was more abundant among saplings. A comparison with 18 permanent plots from a diameter-limit cutting showed that plots had come back to a structure similar to that of the old-growth forest 47 years after cutting. However, spruce ratios had decreased while those of balsam fir and paper birch (Betula papyrifera Marsh.) had increased. Red spruce decrease is not due to a lack of regeneration but to overcutting. Single-tree selection method would be a suitable treatment if aimed at protecting red spruce trees up to a given diameter.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
