The federal wildfire occurrence database lists 17 fires within 5 miles of Opera (historical) between 2012 and 2020, burning about 51 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:

• Wesley
• Hopewell
• Mount Sterling
• Meadow Farm
• Cottage Hill
• Darlington

Every fire recorded in Muskingum County

Museums hold 223 specimens collected within 10 miles of Opera (historical) between 1873 and 1974: 182 Animalia, 26 Plantae, 7 Fungi, 5 Protozoa, 2 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A.E. Miller, Buker, W., Buker, W.E. 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.
