Regional context, not property-specific evidence. Museums hold 107 specimens collected within 10 miles of Cassella between 1886 and 1975: 80 Animalia, 24 Fungi, 1 Unrecorded, 1 Bacteria, 1 Plantae. 12 distinct Species records are shown. Collected by A. D. Selby, Brown, H P, C. Clark 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.
