The federal wildfire occurrence database lists 154 fires within 5 miles of Bald Knob between 1992 and 2020, burning about 1,320 acres in total. 2 started naturally. 49 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:

• Cherryville (historical)
• Kitts Hill
• Andis
• Five Forks
• Manker (historical)

Museums hold 593 specimens collected within 10 miles of Bald Knob between 1840 and 1972: 479 Animalia, 59 Fungi, 54 Plantae, 1 Unrecorded. 12 distinct Species records are shown. Collected by Avery W. B., Bartholomew E., Bartholomew Elam 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.
