Regional context, not property-specific
evidence. Museums hold 6 specimens
collected within 10 miles of Henny Barn between 1943 and 1969: 5 Plantae, 1 Animalia.
5 distinct Species records are shown.
Collected by C A Foster, Jones, G.T., R.L. Stuckey. 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.
Regional context, not property-specific
evidence. The federal mineral resources record lists
8 workings within 5 miles of Henny Barn: 5 past producers, 3 producers.
3 still produce. What was taken out: Limestone, General, Sand and Gravel, Construction, Stone, Crushed/Broken, Limestone, Dimension, Stone, Crushed/Broken. Distance is straight-line from the

settlement's page as well.

It is quoted below word for word, never summarised. The text was read off the scanned case file by machine, so the
occasional stray character is the recogniser's and the 1970s
typewriter's.
