Abstract
Ecosystems are naturally variable. This variability can be due to the inherent land cover, topography, seasonality, and natural variations in climate. Ecosystem variability can also extend beyond this natural range due to disturbances such as fire, harvesting, land conversion, insect infestation, and increasingly may be due to extremes in climate (e.g. snow, ice storms, flooding, rainfall, temperature fluctuation). Differentiating disturbances from natural variability and understanding vegetation productivity changes resulting from disturbances are of high importance for ecosystem management. To capture ecosystem variation over the province of Ontario, Canada, we utilised a series of ten‐day composites of Medium Resolution Imaging Spectroradiometer (MERIS) fraction of Photosynthetically Active Radiation (fPAR) over a 6 year period. We investigated changes in the variations in fPAR derived vegetation indices (annual productivity, degree of vegetation seasonality and vegetative perennial cover) using a non‐parametric statistical test. Results indicated that considerable changes in vegetation productivity are occurring in Eastern Ontario as well as in other more localized regions in northern Ontario. Using a range of auxiliary information on fire disturbance, land cover, distance to nearest road and city, topography and protected areas, we provide explanations as to the possible drivers behind this variability.

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
