Abstract
As an essential indicator of a forest's growth capacity and rate, the increased accuracy, ease of access, processing and visualization of canopy height information can facilitate a targeted range of strategies for sustainable forest management, especially among citizen scientists and community members. Here, forest canopy height is estimated for several land parcel segments in a subarctic locale using ground-based measurements as well as photon and elevation data obtained from NASA's Ice, Cloud, and land Elevation satellite (ICESat-2). ICESat-2 offers a comprehensive view of vegetation structure and provides a unique opportunity to quantify forest canopy height changes, productivity and distribution in remote locations where it is often arduous and cost prohibitive to acquire ground data. Average canopy heights returned from ICESat-2 data compared with field measurements of above-ground biomass yielded a R 2 of 0.53, and root mean square error of 1.45 m, amplifying the use and potential value of this dataset and novel platform for multiple user groups interested in forestry mapping and ongoing monitoring of forest canopy height with increasing frequency to facilitate community-led decision making. This study demonstrates the utility and benefit of integrating remotely sensed data and field-based survey measurements to generate complementary information related to forest structure and diversity in this region.

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
