Museums hold 335 specimens collected within 10 miles of Erhart between 1884 and 1975: 293 Animalia, 24 Plantae, 16 Fungi, 2 Protozoa. 12 distinct Species records are shown. Collected by A. Roberts, Ashcroft, G.B.; O. Berea, B Zahuranec & party 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.
