The federal wildfire occurrence database lists 3 fires within 5 miles of Knaufville between 2019 and 2020, burning about 10 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:

• Bowmans Corners
• Calla
• Greenford
• Hickory Corners
• New Albany
• Patmos

Every fire recorded in Mahoning County

Museums hold 300 specimens collected within 10 miles of Knaufville between 1884 and 1974: 176 Animalia, 103 Plantae, 21 Fungi. 12 distinct Species records are shown. Collected by ?, Anderson, B., Armbruster, D. C. (Daniel C.) 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.

Every working recorded in Mahoning County

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

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1061322. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
