Museums hold 2,305 specimens collected within 10 miles of Air Line Junction between 1863 and 1975: 1,990 Animalia, 159 Fungi, 141 Plantae, 6 Unrecorded, 6 Protozoa, 3 Chromista. 12 distinct Species records are shown. Collected by A. Lose, Aborn, R., Austing, G R 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.
