What “unexplored” means: Mapping undersampled regions in natural history collections

We examined global records of accessible natural history voucher collections (with publicly available data) for terrestrial and freshwater vascular plants, fungi, freshwater fishes, birds, mammals, and herpetofauna (amphibians and reptiles) and highlight areas of the world that would be considered undersampled and sometimes called “unexplored” ( i . e ., have relatively low, or no evidence of, past sampling efforts) under typical Western-scientific descriptions. We also question what “unexplored” may actually mean in these contexts and explain how retiring the term in favor of more nuanced phrasing can mitigate future misunderstandings of natural history science.
