The database integrates Wiesner (2020), Pearson & Vogler (2001), primary taxonomic literature, GBIF occurrence records and iNaturalist observations.

Phenology is encoded as twelve monthly activity flags per taxon, with a separate peak-months field. Distribution is recorded both as free-text (Wiesner 2020) and as ISO country codes.

Each record carries a data-quality score and a confidence profile, so users can judge the strength of the evidence behind it.
