Soil and topographic features affect plant growth on a natural gas pipeline right-of-way in northeastern British Columbia
Bibliographic record
Abstract
Natural gas reserves in northeastern British Columbia (B.C.) are being extracted, yet the effects to soils and plants from industrial disturbance in the region are poorly understood. This study examined soil and topographic factors that affect plant establishment and growth on a reclaimed natural gas pipeline. The study area was located approximately 70 km southeast of Tumbler Ridge, B.C. Field sampling took place between spring 2012 and summer 2013. Soil properties were examined to understand growing conditions at the site, natural regeneration was observed to understand current species diversity, and growth parameters were taken for lodgepole pine and shrubby cinquefoil. Soil nutrients were higher in wetland blocks than upland blocks, and were associated with greater species diversity. Plant growth was greatest in north-facing blocks, however biomass was greatest in crest blocks. Reliance on natural revegetation can delay site recovery, and reclaiming a site requires site-specific plant species in northeastern B.C. --Leaf ii.

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.
