Wilson Farm Habitat Enhancement Project at Colony Farm Regional Park
Bibliographic record
Abstract
The Wilson Farm Habitat Enhancement Project, located within Metro Vancouver's Colony Farm Regional Park, is the largest environmental enhancement undertaking performed as part of the Port Mann Highway 1 (PMH1) improvements and is also among the largest habitat compensation works ever undertaken for a BC transportation project. The park is located near the confluence of the Coquitlam River with the Fraser River, just upstream of the Port Mann crossing. This 65 ha site was high intertidal habitat prior to its conversion to farmland in the early 1900's when dikes were constructed to prevent tidal flows from the Coquitlam River from entering the site. The Wilson Farm Habitat Enhancement Project was based on re-introducing tidal flows into an existing network of agricultural drainage and providing access for young salmon and other fish for the first time in over 100 years. The project includes constructing channels and ponds, installing tide and sluice (overshot) gates, riparian planting and upgrading the existing pump station for fish-friendly operation. The design for this work was initiated in 2008 and was complete in early-2011 with onsite construction of the work being performed during the period of August-October 2011. The project created approximately 3.8 ha of tidally-influenced aquatic habitat and 12.5 ha of associated riparian habitat. During planning and implementation of the Wilson Farm Habitat Enhancement Project, a number of institutional and technical challenges were encountered. To overcome these challenges, innovative solutions were developed to optimize the objectives for fish and wildlife habitat. This project was nominated for the 2011 TAC Environmental Achievement Award. For the covering abstract of this conference see ITRD record 201211RT334E.

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.
