Museums hold 306 specimens collected within 10 miles of Unionville between 1885 and 1975: 217 Animalia, 46 Plantae, 33 Fungi, 10 Chromista. 12 distinct Species records are shown. Collected by A.W. Cusick; R.H.Guckert, Adams J. M. R., Adams J. R. M. 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.

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1065411. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
