It’s monsoon season here in Arizona, and we’re getting thunder, lightning and rain almost every day. The other day, lightning took out a tree, which took out a power line, which caused an important road to be closed. This got me to wondering…

If wood isn’t a conductor, why do trees get struck by lightning so often?!

Air to ground lightning will often strike the tallest thing handy, good conductor or not. And while a tree may not be a great conductor, it definitely IS a conductor.

Only wood without moisture is a good INSULATOR. As Charlie said, it is a conductor.

Trees are conductors when their outsides are wet…and the voltage required to reach a tree is lower than what it takes to reach the ground.
