Restoration of a degraded urban estuary: The MacKay Creek estuary project
Bibliographic record
Abstract
MacKay Creek estuary Over the last century the Mackay Creek estuary was highly modified by industrial activity and infrastructure development on the North Vancouver waterfront. It's historical area was reduced by >90% by infilling to create industrial land, and the remaining estuary habitat had become simplified with minimal estuarine vegetation, no large woody debris and a low head dam which prevented upstream salmonid migration during medium to low tides which exposed adult salmonids to increased marine mammal predation. A large non-regulatory habitat restoration project was initiated in 2013-2014 which involved re-creating estuary edge habitat, removing the low head dam, extensive placement of large woody debris and planting with native tidal and riparian vegetation, and conducting non-native Canada geese control programs. This was the first estuary restoration project completed under the HCTF Burrard Inlet Restoration Pilot Program, and provided valuable lessons for future estuary restoration projects within Burrard Inlet and other urban settings.

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.
