The federal wildfire occurrence database lists 4 fires within 5 miles of Park Ridge Acres between 2002 and 2002, burning about 2 acres in total. 1 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:

• Balentine Acres
• Beatty
• Broadview Acres
• Cedar Hills
• Durbin
• Eagle City

Museums hold 1,445 specimens collected within 10 miles of Park Ridge Acres between 1840 and 1975: 958 Animalia, 338 Plantae, 141 Fungi, 4 Protozoa, 3 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by 73.7; J.H., ?, A JOHN 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.
