    Impacts of Lightning on Trees: Power, Force, & Injury


    Understanding lightning conduction systems and tree protection is one component of professional tree health care.  Lightning generation, attachment, and grounding knowledge is important to appreciate in order to install a tree lightning conduction system.  Knowing how lightning injures a tree helps promote reasons for protecting a tree.  This talk will review new information on lightning interactions with trees, including dispelling myths.  How lightning disrupts and damages trees will be presented.
