Regional context, not property-specific evidence. The federal wildfire occurrence database lists 31 fires within 5 miles of South Bolivar between 1995 and 2020, burning about 88 acres in total. 3 started naturally. 2 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:

• Kossuth
• Alma
• Bolivar
• Hoben
• Little Genesee
• Sawyer

Regional context, not property-specific evidence. Museums hold 140 specimens collected within 10 miles of South Bolivar between 1917 and 1967: 106 Animalia, 33 Plantae, 1 Fungi. 12 distinct Species records are shown. Collected by C. Robins, Charles Robins; John New; Robert Dickerman, D. B. Ward 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 1 working within 5 miles of South Bolivar: 1 producer. All of them still produce. What was taken out: Sand and Gravel, Construction. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 973088.
