Airpark Lagoon Breach - Restoring Habitat Connectivity for Fish
Bibliographic record
Abstract
The Courtenay River channel is located in the K’ómoks Estuary on the eastern side of Vancouver Island. Much of the tidal salt marsh area in the channel was filled in and developed through the mid-1900’s, including diking of a 4 hectare area for the creation of a sewage lagoon in 1963. The loss of tidal salt marsh and changes in flow dynamics impacted the suitability of the area to support rearing and refuge for juvenile salmonids. The Comox Valley Project Watershed Society undertook a project to breach the lagoon dike with a large multi-plate aluminium culvert in order to reconnect the Courtenay River through the upper end of the lagoon to the estuary. Reconnecting river flow through the lagoon provides a flushing and nutrient circulating function that partially restores the original flow dynamics, thereby improving the lagoon habitat for fish. In particular juvenile salmonids will benefit from the improved and accessible habitat for rearing, foraging and refuge. Preliminary results indicate increases in usage patterns by wildlife, specifically fish and birds. Salt marsh habitat restoration was a component of the work undertaken and the project featured strong community engagement with stewardship groups and the local First Nation.

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.
