The federal wildfire occurrence database lists 48 fires within 5 miles of Dorcas between 1992 and 2019, burning about 105 acres in total. None started naturally. 4 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:

• Oakgrove (historical)
• Antiquity
• Condeville
• Racine
• Oldtown Flats
• Spiller

Every fire recorded in Meigs County

Museums hold 296 specimens collected within 10 miles of Dorcas between 1844 and 1973: 223 Animalia, 44 Fungi, 26 Plantae, 3 Chromista. 12 distinct Species records are shown. Collected by Balser, G., Bartholomew, E.A.; Wilson, D., Blankenbaker, et al. 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.

The federal mineral resources record lists 3 workings within 5 miles of Dorcas: 2 past producers, 1 plant. 1 still produces. What was taken out: Chromium, Aluminum, Aluminum, Contained or Metal. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
