Mapping winter food security for the Klinse-Za caribou herd
Bibliographic record
Abstract
In Canada, many wildlife species are in decline, and some of these species, like caribou, are central to the food sovereignty and cultural practices of many Indigenous communities. Alongside actions by the federal and provincial governments, First Nations in northeastern British Columbia are leading recovery efforts for the Klinse-Za caribou herd. Providing natural forage during recovery actions is important for caribou during maternal pens, supplemental feeding, and habitat protection. Since 2013, the Saulteau First Nations and the West Moberly First Nations have captured 12-22 pregnant caribou and held them in a pen for several months per year. The pen prevents predation on mothers and young. At the same time the Nations provide caribou with high quality food resources that include a mixture of commercial pellets and Cladonia lichens (C. rangiferina, C. abbuscula, C. stellaris, C. stygia, C. uncilalis) collected by the Nations. Community members are recruited to pick lichen, which is then dried, stored, and provided to the temporarily penned caribou. Understanding where lichen is available on the landscape and the rates of recovery following lichen harvest are important for the future sustainability of the caribou penning project. Our research project aimed to quantify lichen availability for the next 5 years by: (1) ground-truthing lichen sites to validate and re-parametrize a lichen distribution model; (2) marking new lichen patch extents with a handheld GPS in areas where lichen occurrence, but not extent, was known to the community; (3) monitoring lichen growth and recovery rates, following the harvest of lichen in large patches (> 3 ha) (4) measuring lichen to quantify lichen growth at a fine scale (1m2 plots) following harvest. Our research project led to the discovery of new lichen patches and the extension of existing patches. This will help supply caribou with supplemental food for the next 5-years of caribou recovery in this area. The 5-Year Harvest Plan includes a 1-year supply of lichen produced through increasing the extents of lichen patches, a 2-year supply of lichen based on the predictions from the model, and a 2-year supply of lichen through the re-harvest of two lichen patches.

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.
