Museums hold 2,347 specimens collected within 10 miles of Elden Heights between 1863 and 1975: 2,023 Animalia, 158 Fungi, 153 Plantae, 6 Unrecorded, 5 Chromista, 2 Protozoa. 12 distinct Species records are shown. Collected by A. M. Evans, Aaron J. Sharp, B H AND L W CAMPBELL 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.
