Regional context, not property-specific evidence. The federal wildfire occurrence database lists 360 fires within 5 miles of Heilbronn between 1992 and 2020, burning about 1,759 acres in total. 26 started naturally. 31 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.
