Museums hold 232 specimens collected within 10 miles of Washington Mills between 1896 and 1975: 206 Animalia, 17 Plantae, 8 Fungi, 1 Protozoa. 12 distinct Species records are shown. Collected by A. H. Bauer, Arden R. Gaufin, B. G. Berger 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.
