Abstract
Catastrophic mortality of North American ash ( Fraxinus spp.) caused by Agrilus planipennis Fairmaire has been attributed to the lack of coevolved resistance between native ash species and this Asian invader. Although A. planipennis host preference or tree resistance can vary, all North American ash species are presumably highly vulnerable to A. planipennis. We inventoried live and dead blue ash ( Fraxinus quadrangulata Michx.) and white ash ( Fraxinus americana L.) in two southeastern Michigan woodlots several years after the A. planipennis invasion to assess their survival. Agrilus planipennis populations in this area peaked in approximately 2005, and the region is now characterized by nearly complete ash mortality. At the Plymouth site, 71% of the original 380 blue ash were alive, whereas only 29 saplings of the original 187 white ash were alive. At the Superior Township site, 63% of the original 210 blue ash were living, whereas all 125 white ash were dead. More than 80% of the blue ash had evidence of previous A. planipennis colonization, but 87% appeared healthy in 2011. Tree diameter did not consistently affect survival, and live and dead trees of both species were distributed across sites, indicating that differential survival was not attributable to localized conditions.

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
