Abstract
Representations of vegetation structure are critical for effective forest ecosystem management. Structure is conventionally characterized using aerial photographs and field measurements; however, such methods are time-consuming and subjective, yielding results that cannot be easily updated and lack the detail required for many management initiatives. In contrast, light detection and ranging data provide highly accurate and detailed height, cover and canopy structure estimates, offering an unparalleled information source for improving conventional methods. Although numerous metrics can be derived from light detection and ranging, three suites common to the literature include height percentiles, canopy height descriptors and canopy volume profiles. This study assessed these three metric types for differentiating among vegetation structural classes in the Southern Gulf Islands, Sidney, BC, Canada. Results indicate all metrics could significantly differentiate (i.e. p ≤ 0.01) between structural classes, but that the number of and types of metrics capable of differentiation decreased with increased structural age and complexity.

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
