Museums hold 38 specimens collected within 10 miles of Blackfork between 1898 and 1975: 35 Animalia, 2 Fungi, 1 Plantae. 12 distinct Species records are shown. Collected by DUELLMAN CROFT KNOTTS AND WALTERS, E.H. Metzler, F. Bartley 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.
