Regional context, not property-specific evidence. The federal wildfire occurrence database lists 10 fires within 5 miles of Subrosa (historical) between 2013 and 2020, burning about 61 acres in total. None started naturally. 4 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:

• New Middletown
• Ginger Hill
• Meadowood
• Petersburg
• Lowellville
• Poland Center

Every fire recorded in Mahoning County

Regional context, not property-specific evidence. Museums hold 316 specimens collected within 10 miles of Subrosa (historical) between 1853 and 1973: 163 Animalia, 152 Plantae, 1 Chromista. 12 distinct Species records are shown. Collected by Baird, S. F., Baird, SF, Baird, Spencer Fullerton 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.

Regional context, not property-specific evidence. The federal mineral resources record lists 20 workings within 5 miles of Subrosa (historical): 15 past producers, 5 producers. 5 still produce. What was taken out: Stone, Crushed/Broken, Clay, Limestone, General, Clay, Coal. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
