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 286 specimens collected within 10 miles of Ridgewood Acres between 1875 and 1975: 133 Fungi, 87 Animalia, 62 Plantae, 2 Unrecorded, 2 Protozoa. 12 distinct Species records are shown. Collected by Adams, W., Adams, W. (William), Adams, W.; Adams, S. 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.
