Forestry Water Quality Index – A planning tool for the assessment and communication of the impacts of forestry activities on water quality
Bibliographic record
Abstract
The assessment of the impacts of forestry activities on water quality is a critical component of forestry management and planning, especially when watersheds are being used for different water uses by different stakeholders. Traditional methodologies for assessing these impacts, while accurate, often do not take into account the intended use of water. Water quality data are inherently technical and are not conducive to communication to all stakeholders—especially the public. There is a need for a communications-based assessment tool that assesses the impact of forestry activities on water quality from the perspective of different water uses. This paper describes the development and application of such a tool, the Forestry Water Quality Index (FWQI). The FWQI has been developed specifically to capture, evaluate and communicate the impact of forestry activities on water quality to multiple stakeholders. Initially based on the Canadian Council of Ministers of the Environment's Water Quality Index, the FWQI was specifically adapted for applications in forestry management. Details of this adaptation and its methodology are outlined. Case studies from Newfoundland and Labrador illustrate the use of the FWQI for communication, performance evaluation, and planning and technical data analysis. The FWQI tool has the ability to compare pre- and post-forestry water quality data (communication), determine the effectiveness of best management practices (performance evaluation), predict water quality after forestry activities (planning) and evaluate seasonal variations in water quality (data analysis). These components provide useful information for the evaluation of the effects of forestry activities on water quality and to ensure sustainable forest management. It can be utilized by both forestry and water resources management to ensure sustainable development of the forestry sector. Key words: FWQI, sustainable forest management, water quality, Newfoundland and Labrador

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.
