As many as were there when I started managing the land. Cultivation can
include doing nothing.

Desertification does not grow from lack of fungii, but from miss use,
loss of top soil, changing wheather patterns, etc, ad infinitum.
"Perhaps the fastest way to kill.....is clear cut"? Studies here, or
opinion? To my knowledge (and it is not of depth of a college proff,
but hey, I try) dead wood lacks the necessary requirments for most
root-rots, i.e., phloem and zylem, functional.

I wont go into plant physiology, but the plant structures necessary for
water uptake come with the rooting structure. Can fungi help? Probably
in some circumstance, yes in others.
