Merged phytosociological and geographical approach for multiple scale vegetation mapping as a baseline for public environmental policy in Mexico
Bibliographic record
Abstract
Abstract Questions What is the potential use of maps derived from a merged geographical and phytosociological approach to support the design of public environmental policies? Do these approaches and data sources deliver complementary land‐cover/vegetation maps? Objective The present article documents a joint phytosociological and geographical approach to improve vegetation cartography in temperate‐tropical transitional ecosystems. Location The research was conducted at national (Mexico) and state (Michoacán) scales. Mexico and Michoacán have been recognized as regions of high eco‐geographical complexity, where temperate‐tropical conditions intermingle, creating large eco‐socio‐cultural mosaics. Methods Data from 268 field verification sites and 223 relevés surveyed during the last two decades and recent land cover sources were used as the main inputs. The results were further validated by three workshops with local botanists and field verification during 2021. Results At the national level, Mexico's forests, shrubs, herbs, and non‐vascular major formation classes were hierarchically split by dominant life forms and prevailing climatic affiliations. At the state level, these major formation classes split into 19 sub‐formations, of which 15 were forest communities. Conclusions We discuss the scientific challenge of transitioning from land cover into vegetation maps and (dis)similarities of approaches reviewing concepts and analytical (quanti)qualitative instruments. The paper contrasts the present output with the experiences of other countries such as Canada, the United States, Bolivia, and Colombia. Finally, the results are discussed in light of their relevance for constructing public environmental policies, such as land use planning, establishment of protected areas, allocation of incentives for sustainable environmental services, and long‐term conservation practices.

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.
