Abstract

fetched live from OpenAlex

Climate change is expected to lengthen the growing season for plants in many temperate regions. The purpose of this study is to develop future growth estimates for trees in Earlscourt Park, Toronto. The i-Tree Forecast model, in combination with climate change scenarios provided by the Canadian Climate Change Scenario Network, were used to build trajectories of future tree growth and mortality. Tree growth forecasts were greatest for the climate change scenario with the longest growing season length. Results highlight future vulnerability in two tree species common to the park, honey locust and Norway maple. A comparison of the leaf area estimates produced by i-Tree Streets and i-Tree Eco was also conducted. These models showed differences in their prediction of leaf area, a key metric for ecological service provision. Forecasting tree growth and mortality in urban parks can inform management plans that seek to maximize the flow of future ecological benefits.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
