Museums hold 105 specimens collected within 10 miles of MacAdam (historical) between 1837 and 1967: 96 Animalia, 4 Plantae, 4 Fungi, 1 Chromista. 12 distinct Species records are shown. Collected by Adler, K. K., Bonnewitz L. R.; Stevenson J. A., Bonnewitz Lee R. 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.
