Secondary stand structure and its timber supply implications for mountain pine beetle attacked forests on the Nechako Plateau of British Columbia.
Bibliographic record
Abstract
Post-mountain pine beetle epidemic, secondary stand structure measured in 1370 mature leading pine plots in the central interior of British Columbia indicate significant levels of advanced regeneration (AR) in most Biogeoclimatic (BEC) subzones. Future growth of AR was predicted using SORTIE ND and VDYP7 natural stand growth and yield models with inputs such as species composition, diameter distribution, site index (BHA50), basal area and quadratic mean diameter. The SELES (STSM) spatially explicit landscape event simulation model forecasts timber supply incorporating AR focusing on alleviating predicted mid-term (15 to 60 year) fall-down. SELES forecasts incorporating AR using VDYP7 results in a 6% increase in mean mid-term harvest level for the Prince George Timber Supply Area. If SORTIE ND is used, mid-term forecast is increased by 23%. Additional scenarios show benefits to mid-term timber supply when stands with well developed AR are reserved for harvest until after the initial salvage period. --P.ii.

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.
