Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

Regional context, not property-specific evidence. Museums hold 329 specimens collected within 10 miles of West Clarksville between 1877 and 1965: 292 Animalia, 29 Plantae, 8 Fungi. 12 distinct Species records are shown. Collected by A. C. Latta, C.

This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
