The federal wildfire occurrence database lists 23 fires within 5 miles of Loudon between 2004 and 2019, burning about 39 acres in total. None started naturally. 1 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:

• Beartown
• Columbia
• Parral

Museums hold 594 specimens collected within 10 miles of Loudon between 1851 and 1973: 431 Animalia, 146 Plantae, 14 Fungi, 2 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A W Cusick, A. Cibula, A. Cobula 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.
