Post-fire invasion of Nodding Thistle in a montane 'Poa labillardierei' community
Bibliographic record
Abstract
A high severity fire in Namadgi National Park, ACT, killed significant numbers of the mature tussock grass Poa labillardierei Steud.(River Tussock).The fire took place in Autumn 2018, and resulted in an extensive Carduus nutans L. (Nodding Thistle) invasion the following spring.Nodding Thistle has become the dominant species along the valley floor (25 ha).Standard control measures with selective herbicide have been used but intensive rehabilitation is required (leaky weirs, grazing exclusion) to encourage native plant regeneration.Lessons learnt include: 1) montane River Tussock communities along riparian areas are sensitive to hot fire, particularly when under drought stress; 2) Nodding Thistle invasion supports the 'Augmented' Intermediate Disturbance Hypothesis; and 3) prolonged drought, associated with climate change, is lowering the tolerance of montane River Tussock communities to fire, and reducing biotic resistance to invasive plants.

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.
