Built from recent research-grade iNaturalist observations. Identifications are community-sourced and may occasionally be wrong, and the ranking reflects where people record and photograph wildlife, so a species seen often here is not necessarily rare elsewhere. Some plants and animals are only out in certain seasons. Treat this as a lively snapshot of what people are finding, not a formal checklist.
