Classification of vegetative lagg types and hydrogeomorphic lagg forms in bogs of coastal British Columbia, Canada
Bibliographic record
Abstract
A “lagg” is usually defined as the confined transition zone along the outside margin of a raised bog, characterized by a fen or swamp plant community. It is an important landscape element for biodiversity and helps to maintain a high water table within the peat mass of a bog, but has received little research attention. Greater knowledge of the variability in laggs will improve designation of appropriate conservation sites and restoration of damaged bogs. We therefore examined the hydrological, hydro-chemical, vegetative, and peat characteristics of laggs of bogs in coastal British Columbia, Canada. The 17 studied lagg transects were classified into four vegetative lagg types: Spiraea Thicket, Carex Fen, Peaty Forest, and Direct Transition. These vegetative lagg types fell within two hydrogeomorphic lagg forms: confined or unconfined. The Spiraea Thicket and Carex Fen laggs were topographically confined at the bog margin and characterized by a higher water table and a smaller tree basal area compared to the unconfined Peaty Forest and Direct Transition laggs. Half of the studied laggs were unconfined, highlighting the importance of considering both confined and unconfined laggs in the delineation, conservation, and restoration of raised bog ecosystems.

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.
