The federal wildfire occurrence database lists 16 fires within 5 miles of Merriam between 2002 and 2019, burning about 27 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:

• Blue Rock
• Gaysport
• Stone
• Cedar Run
• Confederate Crossroads (historical)
• Museville

Every fire recorded in Muskingum County

Museums hold 241 specimens collected within 10 miles of Merriam between 1893 and 1971: 224 Animalia, 12 Plantae, 5 Protozoa. 12 distinct Species records are shown. Collected by Adams, W.; Starrett, J., Adams, William, Adler, K. K. 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.
