Hydrologic effects of mountain pine beetle in the interior pine forests of British Columbia: Key questions and current knowledge
Bibliographic record
Abstract
The mountain pine beetle (MPB) (Dendroctonus ponderosae Hopkins) could have a large effect on hydrologic regimes in British Columbia watersheds. Given the recent increase in size of the beetle infestation, many questions around forest management, particularly salvage harvesting, have emerged. Unfortunately, information to address these questions is limited to a handful of research studies. Although local initiatives to address knowledge gaps are under way, it is important to use the best available science to guide current management decisions related to MPB. This article highlights some of the key hydrologic questions associated with the MPB epidemic, identifies current knowledge on the effects of MPB on watershed hydrology, shows where research information is lacking, and comments on future directions for research. The effects of MPB on stream channel stability, water quality, hillslope processes, riparian function, and fisheries are not discussed. We hope this brief article will stimulate further discussion amongst hydrologists and foresters in British Columbia.

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.
