Museums hold 98 specimens collected within 10 miles of Van between 1862 and 1975: 78 Animalia, 19 Fungi, 1 Plantae. 12 distinct Species records are shown. Collected by A. R. Gaufin, A.R. Gaufin, H.H. Ross, Arden R. Gaufin 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.
