Restoration richness tipping point meta‐analysis: finding the sweet spot
Bibliographic record
Abstract
Species richness is a fundamental component of ecological research including restoration. Managing for enhanced native species richness in restoration is a powerful goal and outcome; nonetheless, local species richness can also be used as a proximate mechanism to decide on the lands to acquire, protect, and restore. Here, a meta‐analysis was used to test the hypothesis that local species richness is a viable consideration in predicting varied restoration outcomes as identified by the primary researchers for drylands. In all dryland contexts, the most effective restoration outcomes across varied restoration interventions were at mid‐to‐relatively lower species rich sites. Consequently, restoration of degraded or low diversity arid grasslands is an important strategic opportunity during the UN Decade on Ecosystem Restoration, and plant species richness is an excellent starting point to inform decisions.

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.
