For years W4KFC ran long wires through the woods. They played.

I have heard this business about staying out of the woods with
verticals for years. But I have never heard it quantified. But then
how would one do a controlled experiment, particularly since ground
conductivity has such a big effect?

Put up a vertical in the woods, with a receiving antenna a mile away
in the woods. Measure. Cut down all the trees in between. Remeasure.
