Default Wire Antenna/ Tree interaction

You can match any thing to a transmitter with a good antenna tuner, the
question is the radiation resistance low enough to efficently transfer
energy to free space?

When using a G5RV that was close but not touching the branch of tree I got a
flat match, could receive well but did not get out worth a damn. Moving the
antenna to an area where there were no trees and using 2 30 Rohn telescopic
masts as end poles made a big difference, got a flat match, RX and TX were
great.

My 2 cents worth on the subject but I as usual someone will say they
transmit great with the branchs laying right on the wire.

I agree with the arcing and fire saw that happen when a wet branch connected
with a 660 VAC line on a utility pole once.

I'm a noob, and I'm considering installing a wire antenna using the
sole tree on my lot as one end. My question is "Is it dangerous if
the antenna touches the tree branches/leaves during transmit?" I'm
less worried about performance right now and more safety.
