The federal wildfire occurrence database lists 44 fires within 5 miles of Duncan Falls between 2002 and 2019, burning about 83 acres in total. None started naturally. None was 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:

• Philo
• White Eyes Town (historical)
• Confederate Crossroads (historical)
• Griffin
• Hidden Mound

Museums hold 733 specimens collected within 10 miles of Duncan Falls between 1873 and 1975: 659 Animalia, 49 Plantae, 15 Fungi, 5 Protozoa, 4 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A.E. Miller, Adams, W., Adams, W. (William), Trautman, M. B. (Milton Bernard) et al. 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.
