The federal wildfire occurrence database lists 5 fires within 5 miles of Bluff (historical) between 2012 and 2018, burning about 6 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:

• Owls Town (historical)
• Walhonding
• New Princeton
• Spring Mountain
• Tiverton Center
• Cavallo

Every fire recorded in Coshocton County

Museums hold 528 specimens collected within 10 miles of Bluff (historical) between 1898 and 1974: 505 Animalia, 23 Plantae. 12 distinct Species records are shown. Collected by C. Stein, C. Stein, R. Johnson & J. Jenkinson, Cavender, M. (Marlin) 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.
