The resistance measured between 1/4" spike nails driven in 2 feet 
apart in the same tree (big nails for railroad ties, etc) also 
measures over 1 megohm, the same as the probe points. I don't see any 
change.

Any contact size effects seem swamped by the high resistivity of the 
tree.

We are still left with an extremely resistive "conductor".
