Museums hold 791 specimens collected within 10 miles of Mackachack (historical) between 1862 and 1975: 752 Animalia, 20 Plantae, 18 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. D. Selby, A. R. Gaufin, A. Spreitzer 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.
