Contemporary forest harvesting impactson water quality and treatability
Bibliographic record
Abstract
Forested landscapes are critical source regions for the supply of drinking water globally. The increasing frequency and severity of climate shocks (e.g., wildfire, floods) in these regions can deteriorate source water quality. Forest harvesting has been proposed as an allied component of forest fuel management and pre-emptive mitigation of disturbance impacts on source water quality and treatability; however, forest harvesting can also deteriorate source quality and compromise treatability in the absence of sufficient operational response capacity. Critically, the impacts of forest harvesting on drinking water treatability have not been reported. Here, drinking water source quality and treatability impacts of three contemporary forest harvesting approaches (clear-cut with patch retention, strip-shelterwood cut, and partial cut) were evaluated in Alberta, Canada. Stream water turbidity, the concentration and character of dissolved organic matter, and disinfection by-product formation potential were evaluated over four years, in harvested and reference watersheds. No appreciable impacts of forest harvesting on water quality and treatability were observed. The results suggest that contemporary forest harvesting approaches may show promise as source water protection technologies for mitigating climate-exacerbated disturbance threats to drinking water treatability; however, further study is needed to establish causality and the contributions of other biotic and abiotic factors.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
