Regional context, not property-specific evidence. The federal wildfire occurrence database lists 54 fires within 5 miles of Obi between 1992 and 2016, burning about 77 acres in total. 6 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:

• Ceres
• Sanford
• Bowler
• Little Genesee
• Bolivar
• Germantown

Regional context, not property-specific evidence. Museums hold 295 specimens collected within 10 miles of Obi between 1877 and 1965: 261 Animalia, 30 Plantae, 4 Fungi. 12 distinct Species records are shown. Collected by C. Robins, C.F. Stone, Ch. H. Peck 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.

Regional context, not property-specific evidence. The federal mineral resources record lists 4 workings within 5 miles of Obi: 3 producers, 1 past producer. 3 still produce. What was taken out: Sand and Gravel, Construction, Salt. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
