Abstract

fetched live from OpenAlex

Subregions are ecosystems of mesoscale size occurring between macroscale ecoregions of national extent and landscape units of subregional area within the U.S. Forest Service hierarchical classification framework of ecological units. The objective of this multi-disciplinary project was to develop a consistent national map of subregions from regional map products that had been developed independently by regional teams working with academic and conservation groups knowledgeable of ecosystems at local and state scales. Regional maps were joined and ecosystems were reviewed for consistency by a small national team consisting of representatives from each regional group. The national map received additional independent review for revision and refinement of ecosystems. The rationale and methodology for delineation of ecosystems shown on the map 'Ecological Subregions: Sections and Subsections of the Conterminous United States' is described in this report. Components of climate, geology, landform, soils and vegetation were integrated to form 190 sections and 1,234 subsection map units. This map represents the first approximation of ecological units at the subregions scale in the western U.S. and is a refinement of a 1995 map of Eastern subregions. Following its publication in 2007, the subregions map provides a basis for ecological mapping on Forest Service lands at the next lower finer scale: landtype associations. Case studies demonstrate use of the subregion map for ecosystem analysis in the Great Lakes Area and Appalachian Mountains in the southern United States. The 2007 map of subregions, supporting documents on methodology and databases of selected environmental data are available on CD. *Note: This abstract supplements and updates a preliminary report on the same topic that was presented, but not published, at the 2007 NAFEW, in Vancouver.

Not 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.
