Museums hold 244 specimens collected within 10 miles of Denmark (historical) between 1893 and 1971: 219 Animalia, 23 Fungi, 2 Plantae. 12 distinct Species records are shown. Collected by Adler, K. K., Anson A. Hinkley, Bauer, 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.
