The federal wildfire occurrence database lists 28 fires within 5 miles of Londonderry between 2005 and 2018, burning about 155 acres in total. None started naturally. 3 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:

• West Junction
• Lickskillet
• Vigo

Museums hold 980 specimens collected within 10 miles of Londonderry between 1923 and 1975: 884 Animalia, 48 Fungi, 43 Plantae, 5 Protozoa. 12 distinct Species records are shown. Collected by A. C. Lincoln, A. Cronquist, A. Spreitzer 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.
