Museums hold 3,081 specimens collected within 10 miles of Ridgeville between 1844 and 1975: 2,966 Animalia, 55 Plantae, 47 Fungi, 11 Unrecorded, 2 Protozoa. 12 distinct Species records are shown. Collected by A Schwartz, A. R. Gaufin, A.C. Borror 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.
