A survey of vascular plant species in paired shrub and open microsites in southern California drylands
Bibliographic record
Abstract
We conducted vegetation surveys across several sites in southern California drylands in early spring 2023 to identify patterns in plant diversity across habitat types and an aridity gradient. Locations sampled include sites in Carrizo Plains National Monument, Cuyama Valley, and sites near Tecopa and Semitropic. Surveys were conducted at two spatial scales - 1m x 1m2 paired quadrats and 1m x 10m transects. All plants in 1m2 quadrats and 10m2 transect were identified to species. In quadrats, all individuals were counted, while in transects total percent cover was estimated. Quadrats were placed under randomly selected shrubs and a paired open plot in shrub habitats, and randomly selected paired locations in open habitats. The dominant shrub species was Ephedra californica at most sites. This survey continues long-term vegetation tracking in California drylands aimed at understanding how foundational species influence regional plant diversity.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
