Abstract

fetched live from OpenAlex

The biogeoclimatic approach to ecosystem classification is unique in that it defines, albeit arbitrarily, an ecosystem, and draws from several of the European and North American schools of vegetation and environment classifications. Undisputedly, the classification has provided a predictive tool for foresters in British Columbia and has given impetus for developing similar classifications elsewhere. The aim of this classification system is to organize forest ecosystems according to relationships in climate, vegetation, site quality, and time. The system is vegetation driven and features three independent, but connected classifications: zonal, vegetation, and site. Site classification is a primary tool used for identifying quality of forest sites. Furthermore, it provides a framework for accumulated, site-specific knowledge about ecological characteristics of plant species, sites, and ecosystems. As a result, the site classification supports a variety of stand - and forest-level decisions as well as forest productivity research.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
