Museums hold 735 specimens collected within 10 miles of Six Mile between 1835 and 1975: 581 Animalia, 85 Plantae, 61 Fungi, 4 Chromista, 3 Protozoa, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. E. Foeerste, A. E. Foerste, A. F. Foerste 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.
