Data and code for taxonomic and model-quality uncertainty in snakebark maple diversity hotspots

Processed non-sensitive data, executable analysis code, frozen taxonomic ledgers, model-evaluation summaries, present-day diversity outputs, model-limited species-level future projections, figure and table source files, and provenance manifests supporting a conservation-biogeography analysis of Acer sect. Macrantha. Exact occurrence coordinates and sampled background locations are not redistributed. The pre-specified coverage gate prohibited clade-level future diversity inference; future outputs are limited to nine eligible species and must not be stacked as clade-wide diversity.
