when trees are being attached by gypsy moths, they start to release a pheramone type substance (via leaves and roots.)

other nearby trees (of the same species) respond by making their leaves more toxic (in the case of Oaks, they produce more tannins)
this makes the near by trees less attractive as food to the moths catapillars.

is this telapathic?

why would trees communicate at all, (and why would other trees respond to the communications?

we tend to think plants just sit there, defensiveless... but..

as to xen or scientology, or for that matter, any other religious beleivies or tenets.. that subject is not up for discussion on this board.

(OH, i know, you forgot.. again!)

well the trees communicate danger.
