The federal wildfire occurrence database lists 1 fire within 5 miles of Irwin between 2002 and 2002, burning about 1 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 209 specimens collected within 10 miles of Irwin between 1926 and 1970: 202 Animalia, 6 Plantae, 1 Fungi. 12 distinct Species records are shown. Collected by Andrew R. Moldenke, D.L. Caldwell, Kettler 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.
