A summary of every public record.
The collections overlap — a road-killed invasive animal is in roadkill and in invasive — so their shares add up to more than 100%.
Roadkill is strongly seasonal — amphibians during the spring migration, snakes through the warm months.

Follow a species for its distribution map and details.
The places with the most records, and the animal recorded most often in each. Each place is a square about 5 km across. Blurred records are left out, because where they are shown is not where the animal was. Follow one to see it on the map.
Of 46,336 public records, 7,185 are shown at a blurred location: the species is protected by law or rated sensitive in the Taiwan species checklist (TaiCOL), or the record has not been identified yet. They still count in every statistic here; only their place on the map is approximate.
