Museums hold 83 specimens collected within 10 miles of Calm (historical) between 1885 and 1975: 42 Animalia, 38 Plantae, 3 Fungi. 12 distinct Species records are shown. Collected by Armbruster, D. C. (Daniel C.), Beardslee, H.C., C.N. Cloes 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.

All 83 specimens within 10 miles, at the Global Biodiversity Information Facility.

The federal mineral resources record lists 2 workings within 5 miles of Calm (historical): 1 past producer, 1 producer. 1 still produces. What was taken out: Stone, Crushed/Broken. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Every working recorded in Geauga County

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.
