Abstract
The giant African land snail (Lissachatina fulica), a highly invasive species, was found infesting cardamom (Elettaria cardamomum) plants in Cardamom Hill Reserve in the Western Ghat region of Kerala state, India, marking the instance of an invasive pest damaging a major spice crop.The present study documents the snail's spread across 14 localities at elevations of 812-1308 m above sea level, an unusual habitat, given its historical confinement to lower altitudes.Field surveys (2021-2025) revealed considerable damage, with 40%-60% yield loss, due to feeding on floral buds, leaves, and young fruits.The infestation's timing suggests a link to Kerala's 2018 and 2019 floods, which may have facilitated snail dispersal through relief materials.Climate change could have further enabled the snail's adaptation to higher elevations.Urgent management strategies are needed to align with global biodiversity frameworks, such as the Kunming-Montreal Global Biodiversity Framework and India's National Biodiversity Strategy and Action Plan (2024-2030), in order to mitigate ecological and economic impacts.The present study highlights the role of extreme weather events in accelerating biological invasions and emphasises the need for strengthened quarantine measures to prevent future spread.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
