Occurrence data for three <i>Plethodon</i> species

Cleaned and thinned occurrence data used for ecological niche modeling in Waldron et al. (2025). Data are provided for three species: Plethodon cinereus (cin-thin.csv), P. electromorphus (ele-thin.csv), and P. richmondi (ric-thin.csv). Two additional datasets represent the subset P. cinereus occurrences within the geographic range polygon of P. electromorphus (cinele-thin.csv) and the combined occurrence data of P. electromorphus and P. richmondi (eleric-thin.csv).
