Abstract

fetched live from OpenAlex

SUMMARY The age structure of a stand provides an understanding of important ecological processes taking place during stand development. The age of trees has been estimated by historical records, estimation from tree size, ring counting at breast height and ground level, pith node counting, and dendrochronological cross dating. Each of these methods has inherent advantages and limitations. In the fire-driven boreal forest, stand age structure has been found to shift from a relatively even-aged structure, where all trees establish immediately after fire with a similar height and diameter, to one that is uneven-aged, where trees vary in height and diameter as time since fire increases. The age structure dynamics differ with stand species composition and influenced by non-stand replacing disturbances. Traditional forest management can shift the age structure at both the stand and landscape level, but silvicultural systems and forest management planning techniques are available to mimic natural age structural patterns.

Full frame distilled prediction

Teacher imitation

Not 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.
