    Trees are masters of both self-defense and communication. Scientists have found that when attacked by insects, trees can flood their leaves with chemicals called phenolics. These noxious compounds are distasteful to tree pests and can even impede their growth. What’s amazing is that once a tree is attacked, it will “signal” to other nearby trees to also start their self-defense, before they are attacked! Methods of communication include releasing chemicals into the wind and possibly even sending chemical or electric signals through the michorizal network of roots (a network of shared fungus fibers).
