Decision tree and random forest classifiers quantified environmental differentiation between ranges, and feature contributions were aggregated by domain (climate, topography, soil, land cover). Robustness was assessed using spatially blocked cross-validation, grouped-permutation importance (which is reduces sensitivity to within-domain collinearity), exact permutation tests, sample-size sensitivity analysis and comparison with classical niche overlap metrics.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Native and invasive occurrences were consistently distinguishable (random forest accuracy 98.2%–100.0%). Intercontinental invaders were differentiated predominantly along climatic axes (57%–76% of model importance), with topography contributing negligibly, whereas within-continent invaders retained climate as the dominant axis (~42%) but showed a substantial secondary topographic contribution (~33%), including river network position.
