Regional context, not property-specific evidence. The federal wildfire occurrence database lists 50 fires within 5 miles of Rockville between 1997 and 2017, burning about 62 acres in total. 2 started naturally. 9 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.

Settlements close enough to share some of these fires:

• Marshall
• Belfast
• Bellville
• Black Creek
• Lyons Corners
• McGrawville

Regional context, not property-specific evidence. Museums hold 482 specimens collected within 10 miles of Rockville between 1860 and 1974: 400 Animalia, 60 Plantae, 19 Fungi, 3 Chromista. 12 distinct Species records are shown. Collected by A. C. Latta, Andrew R. Moldenke, Arnold, C. P. and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
