Ecological description and classification of some pine mushroom habitat in British Columbia
Bibliographic record
Abstract
This extension note summarizes the biology, traditional use, harvest method, and habitat of pine mushrooms in British Columbia and briefly discusses how information on habitat can be used to integrate important pine mushroom areas into timber harvest planning.The pine mushroom (Tricholoma magnivelare) is the most economically important species of wild mushroom harvested from the forests of British Columbia. Various factors, including natural variability in annual mushroom productivity and the method of harvest, are thought to influence wild mushroom production, but few benchmark measurements of commercial mushroom productivity are available. Information is needed on the types of stands and ecosystems in which these mushrooms occur.Soil, vegetation, and forests known to support commercial crops of pine mushrooms across the province are described. Forest subzone, elevation, slope, aspect, and landform all varied between study sites. In general, the soil, vegetation, and forest stand results indicate that submesic site series correlate well with commercial pine mushroom habitat.The results of this study illustrate that pine mushroom habitat capable of producing commercial crops displays certain characteristics and that pine mushrooms do not grow randomly. We recommend that the information from this study be used to define, expand, and map commercial pine mushroom sites. Forest planners can then use these maps to integrate the harvest of pine mushrooms with timber production objectives. Also, certain forest management techniques may be used to enhance mushroom production while meeting some timber objectives. More research is needed to determine which techniques could be applied to North American forests.

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.
