The federal wildfire occurrence database lists 1 fire within 5 miles of Walnut between 2019 and 2019, 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.

Museums hold 1,580 specimens collected within 10 miles of Walnut between 1876 and 1975: 1,398 Animalia, 141 Fungi, 39 Plantae, 2 Unrecorded. 12 distinct Species records are shown. Collected by Adams, W.; Bartley, F., Arledge, F., B. R. & B. D. Bales 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 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 1063080. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
