Museums hold 34 specimens collected within 10 miles of Thomsontown (historical) between 1890 and 1969: 23 Animalia, 7 Plantae, 4 Fungi. 12 distinct Species records are shown. Collected by C A Foster, Class & Daiber, F. C. (Frank C.), Edson H. A.; Pierstorff 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.
