Museums hold 4,644 specimens collected within 10 miles of Hazelwood between 1819 and 1975: 3,267 Fungi, 748 Animalia, 344 Plantae, 253 Protozoa, 24 Unrecorded, 8 Chromista. 12 distinct Species records are shown. Collected by 14753, A. Braun, A. Gaufin 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.
