Water Table and Vegetation Response to Ditch Blocking: Restoration of a Raised Bog in Southwestern British Columbia
Bibliographic record
Abstract
Large-scale peat harvesting operations alter hydrology of raised bogs so that natural regeneration may not occur without altering the water table. This paper describes efforts to restore key hydrologic and ecologic processes in a southwest BC raised bog (Burns Bog) highly disturbed by decades of peat extraction, drainage, filling, and conversion to agriculture, urban, and industrial uses. The restoration goals are to return a high water table throughout the bog, but particularly in the pine forests at the edge of the bog, to re-establish Sphagnum cover, and to re-start the peat-forming process in degraded peat-harvested sectors. Peripheral and interior ditches are being blocked to increase the retention of winter precipitation into the drier summer months. Piezometer/well measurements have detected water table increases in the past two years, including a relatively immediate response in one site. New Sphagnum colonies have become established in the dry perimeter forest, a first indication that the water table may be rising and that peat-forming vegetation may be responding positively. These preliminary results suggest that it is possible to detect a rapid hydrological response with a comprehensive monitoring network in raised bogs; this observation is key to early prediction of future peatland restoration initiatives.

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.
