Arrow IFPA Series: Note 5 of 8: Criterion1: Biological richness
Bibliographic record
Abstract
This extension note is the fifth in a series of eight that describes a set of tools and processes developed to support sustainable forest management planning and its pilot application in the Arrow Timber Supply Area (TSA). It summarizes the criterion and indicators used to set thresholds and evaluate potential impacts on biological diversity for the sustainable forest management (SFM) pilot basecase analysis for Lemon Landscape Unit. Initial thresholds were developed for some indicators, and measures for others, to assess the SFM basecase harvest scenario. Although this did not represent a comprehensive evaluation, preliminary results indicate that under the SFM basecase scenario, habitat attributes (e.g., snags) associated with late seral stands were met primarily in the non-harvested land base, and may be unsustainable for biodiversity objectives. Retention strategies in the harvested land base are therefore important, but could not be assessed for their potential contribution to late seral attributes because of the lack of available models.This extension note provides both an example of how criteria and indicators can be applied to evaluate SFM scenarios, using indicators to set targets and thresholds, and a framework for evaluation. Some indicators, based on dynamic habitat elements (e.g., snags, downed wood, and understorey vegetation), require models to project these elements across a range of stand types and stand treatments. If these models are to act as effective tools, further development and refinement is required to ensure that they are calibrated and verified with field data. Our understanding of habitat thresholds also needs improvement to better define risks and appropriate management responses.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
