I have had temporary dipoles touch branches and there was no issue however
the areas touching were closer to the dipole center than the ends. So if you
can avoid having the ends touch it may work with regular THHN wire.
For a while, I had a 160M dipole that came in contact with redwood
branches at one end. I regularly ran it close to legal limit. When I
dropped it to tweak lengths, I saw that the THHN wire insulation was
scorched.
I agree that this is unlikely to occur at contact points not so close to
the ends where voltages are low enough to not arc or couple to the
vegetation.
