The federal wildfire occurrence database lists 22 fires within 5 miles of Signal between 2005 and 2020, burning about 20 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:

• Rogers
• Clarkson
• East Carmel
• Mill Rock
• Union Ridge
• Achor

Museums hold 668 specimens collected within 10 miles of Signal between 1885 and 1975: 455 Animalia, 184 Plantae, 28 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by Adler, K. K., Andreas, B.; Cusick, A.W., Armbruster, D. C. (Daniel C.) 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.
