Regional context, not property-specific evidence. The federal wildfire occurrence database lists 41 fires within 5 miles of Elm Valley between 2000 and 2019, burning about 89 acres in total. 2 started naturally. 2 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:

• Dyke (historical)
• Andover
• Stannards
• Fulmer Valley
• Hallsport
• Wellsville

Every fire recorded in Allegany County

Regional context, not property-specific evidence. Museums hold 462 specimens collected within 10 miles of Elm Valley between 1870 and 1973: 364 Animalia, 80 Plantae, 14 Fungi, 3 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A. Hazzard, A. L. Moldenke, A. P. Garber 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.
