The federal wildfire occurrence database lists 3 fires within 5 miles of Silica between 2017 and 2020, burning about 23 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:

• Bowen (historical)
• Centennial
• Central Avenue Park
• Mitchaw
• Arrowhead Lake
• Business Corner

Museums hold 1,923 specimens collected within 10 miles of Silica between 1885 and 1975: 1,584 Animalia, 178 Plantae, 148 Fungi, 6 Unrecorded, 5 Chromista, 2 Protozoa. 12 distinct Species records are shown. Collected by A. Lose, A.E. Daugherty, Aaron J. Sharp 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.
