How does white oak trees move?
White oak trees are shorter and wider than most trees around
them. By being wider, they shade out seedlings that would grow into
taller trees and shade them out. By being shorter, they let
lightning hit and kill the taller trees. Once the taller trees
growing right around them die, others do not replace them. They are
still short so that lightning hits other trees. Lightning hits
those trees which are replaced.
