Museums hold 313 specimens collected within 10 miles of Claridon between 1837 and 1975: 299 Animalia, 8 Plantae, 6 Fungi. 12 distinct Species records are shown. Collected by A. Ogilvie, Acker, G., Baumgartner, L. 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.
