Revegetation at the Sullivan Mine – research to closure – a case study
Bibliographic record
Abstract
The Sullivan orebody was a world class iron-lead-zinc sulphide deposit that was discovered in 1892 near what became Kimberley, BC. The Sullivan Mine operated from 1910 to 2001. A research programme to investigate the conversion of waste rock dumps and tailing ponds into productive forest and rangeland was initiated in 1972. Initial studies focussed on revegetation treatments for waste rock and mill tailings. Studies demonstrated that complex covers with at least 30 cm of growth medium is required to grow a satisfactory grass dominated plant community and at least 60 cm is required where alfalfa is a desired component. The studies also indicated that a float rock capillary barrier in the complex cover reduced the movement of acids, salts and metals into the growth medium. The reclamation plan prescribed the installation of native tree and shrub islands and corridors, extensive revegetation with agronomic grass and legume species and inclusions of small islands of native grasses. Native tree and shrub screening trials were used to determine which species would have adequate survival rates to contribute to the development of the wildlife habitat end use objectives. Treatments that created conditions that were free from competitive vegetation were tested to improve the probability of tree and shrub planting success. Revegetation strategies that include the incorporation of native grass and legume islands need to consider the invasive nature of agronomic species with appropriately sized (large) islands. In addition, native tree and shrub islands and corridors need to be large enough to create unique and purposeful wildlife habitats. The long term succession in agronomic plant communities will be assessed through a rationalised monitoring programme. In the future, the plan is to incorporate the investigation of other ecological parameters including soil development, root development, soil flora and fauna, and use patterns by a range of wildlife species.

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.
