Abstract
Sugar maple (<i>Acer saccharum</i>) is a highly valued tree in United States (US) and Canada, and its sap when collected from taps and concentrated, makes a delicious syrup. Understanding how this resource may be impacted by climate change and other threats is essential to continue management for maple syrup into the future. Here, we evaluate the current distribution of maple syrup production across twenty-three states within the US and estimate the current potential sugar maple resource based on tree inventory data. We model and project the potential habitat responses of sugar maple using a species distribution model with climate change under two future General Circulation Models (GCM) and emission scenarios and three time periods (2040, 2070, 2100). Our results show that under GFDL-A1Fi (high CO<sub>2</sub> emissions), sugar maple habitat is projected to decline (mean ratio of future habitat to current habitat per state = 0.46, sd ± 0.33), which could lead to reduced maple syrup production per tree and nearly 5 million additional taps required to maintain current projection levels. If global emissions are reduced and follow a lower trajectory of warming (under PCM-B1), then habitat for the species may be maintained but would still require management intervention. Finally, our results point to regions, particularly along the northern tier, where both climate change impacts and currently developing sugar maple habitat may signify viable opportunities to increase maple syrup production.<b>EDITED BY</b> Christine Fürst <b>EDITED BY</b> Christine Fürst

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
