Museums hold 751 specimens collected within 10 miles of Crownover Mill between 1898 and 1975: 727 Animalia, 24 Plantae. 12 distinct Species records are shown. Collected by Abbott, R; and others, Abbott, R; vonder Heyden, Jonna, Bartley, F. 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.
