Museums hold 253 specimens collected within 10 miles of Kellker (historical) between 1837 and 1975: 242 Animalia, 7 Plantae, 3 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by Bird, C., Breiding, G. (George), C. G. Lloyd 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.
