Museums hold 6,664 specimens collected within 10 miles of Violet (historical) between 1871 and 1975: 5,331 Animalia, 1,179 Plantae, 136 Fungi, 8 Chromista, 6 Protozoa, 4 Unrecorded. 12 distinct Species records are shown. Collected by A. D. Selby, A. F. Satterthwait, A. J. Eames 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.
