Regional context, not property-specific evidence. Museums hold 252 specimens collected within 10 miles of Southworth between 1865 and 1975: 250 Animalia, 2 Plantae. 12 distinct Species records are shown. Collected by *ood, Almen N., Buhlman, M. & Buhlman, M., Bureau of Fisheries 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.
