Museums hold 1,457 specimens collected within 10 miles of Troyton between 1837 and 1975: 1,257 Animalia, 94 Fungi, 92 Plantae, 6 Protozoa, 4 Unrecorded, 4 Chromista. 12 distinct Species records are shown. Collected by A.P. Morgan, Adler, K. K., Allgeyer, S. M. 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.
