The federal wildfire occurrence database lists 7 fires within 5 miles of Oak Knoll between 2002 and 2002, burning about 2 acres in total. None 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:

• Eagle Creek
• Eaglewood
• Hunters Chase
• Air View Acres
• Bellaire Gardens
• Chateau Ridge

Every fire recorded in Marion County

Museums hold 366 specimens collected within 10 miles of Oak Knoll between 1892 and 1975: 353 Animalia, 8 Fungi, 5 Plantae. 12 distinct Species records are shown. Collected by A. Ogilvie, Acker, G., Baumgartner, L. 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 4 workings within 5 miles of Oak Knoll: 4 producers. All of them still produce. What was taken out: Sand and Gravel, Construction, 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.
