Museums hold 2,837 specimens collected within 10 miles of Alum Creek between 1850 and 1975: 2,657 Animalia, 93 Plantae, 85 Fungi, 1 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A C Whitney, A S BRADSHAW, A. P. Morgan 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.
