Well, I can say with pretty good assurance that a wooden pole, wet or 
dry, doesn't affect the currents flowing through a surrounding aluminum 
tube.  The currents in the aluminum tube flow on the outside of it.

Whether or not a tree surrounded by a cage of wires an appreciable 
portion of a wavelength long behaves the same way depends, I guess, upon 
how well the cage of wires actually approximates a tube.  Why don't you 
model it as Jim Lux suggested and let us know?  If it acts like a tube 
it would likely be pretty efficient in spite of what I stated earlier.
