NEC-LIST: Resistance of Trees

Good day all.

I have received a query concerning the electrical resistance of
trees. I know there have been some articles on using trees as
antennas, and may be able to track down at least one of them.
However, sticking a loop around a tree to feed it as an antenna is
somewhat different from knowing the electrical resistance.

Can anyone out there give me suitable reference?

Best regards,
Duncan.
