Museums hold 321 specimens collected within 10 miles of Bald Knobs between 1844 and 1973: 250 Animalia, 43 Fungi, 25 Plantae, 3 Chromista. 12 distinct Species records are shown. Collected by C. H. Jones, Carroll H. D., Carroll, G. 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.
