The federal wildfire occurrence database lists 65 fires within 5 miles of Riverdale between 2003 and 2020, burning about 118 acres in total. None started naturally. 1 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:

• Bethel
• Camp

Museums hold 1,663 specimens collected within 10 miles of Riverdale between 1889 and 1975: 1,504 Animalia, 117 Fungi, 40 Plantae, 2 Protozoa. 12 distinct Species records are shown. Collected by Allen, E. (Ed), B. W. Evermann, Bales, B. R. 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.
