Overview

Modeling study demonstrates an uncertainty-aware dual-filter framework optimizes priority habitat zoning for endangered plants, highlighting robust strategies for conservation planning.

Key Points

Develop and evaluate a dual-filter spatial overlay framework that integrates machine learning ensembles and inter-model disagreement to identify high-confidence habitat conservation priorities.
Calibrated four machine learning algorithms (RF, GBM, ANN, DNN) against 11 environmental predictors—including Landsat-derived indices, climate, soil, and topography—for the endangered montane plant Rheum ribes L. in northeastern Iran.
Combined individual model projections into a True Skill Statistic (TSS)-weighted ensemble and quantified algorithm convergence using spatial congruence metrics (Schoener’s D, Hellinger’s I).
The TSS-weighted ensemble achieved the highest overall predictive accuracy (AUC = 0.94, TSS = 0.75).
Tree-based algorithms demonstrated superior spatial congruence with the ensemble (GBM: D = 0.81, I = 0.89; RF: D = 0.73, I = 0.84) compared to neural network architectures.
The uncertainty-aware dual-filter framework designated 19.2% of the study area as high-priority conservation habitat where high suitability and low inter-model disagreement converged.
