- Species
- Sightings shared by Taiwan's biodiversity research network (TBiA), checked against the national species list (TaiCOL) for conservation status. If TBiA is unavailable, the global GBIF records are used instead.
- Plant growth
- NASA satellite estimates of how much carbon plants absorb in a year, added up over the search area.
- Very busy areas
- Where records run into the tens of thousands, the search stops after 40,000 records or once new records stop adding species. The record count is still exact, but a few rarely seen species may be missing; those sites are marked.
