A results-based system for regulating reforestation obligations: Some developments in 2003
Bibliographic record
Abstract
In a recent paper, we described a multi-block approach to the regulation and management of reforestation (P.J. Martin, S. Browne-Clayton, and E. McWilliams (2002), "A results-based system for regulating reforestation obligations," Forestry Chronicle 78(4): 492–498). Under the multi-block approach, indicators are devised that portray the degree to which the condition of regeneration on harvested areas is consistent with forest management goals. A population of harvested areas is sampled. The current levels of the indicators are estimated and compared to threshold values. If observed levels exceed threshold levels, the population is considered adequately reforested and all reforestation obligations are met. In this paper, we describe some recent enhancements of this concept and demonstrate how the multi-block approach provides characteristics desirable in a regulatory regime. By shifting the focus of reforestation regulation from the stand level to the level of a population of harvested areas, the multi-block approach provides effective regulation, permits efficient management, and addresses several shortcomings in British Columbia's current reforestation regulations. Key words: reforestation, regulation, British Columbia, indicators, multi-block approach

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
