LIGHTNING

lightning Electricity seeks the path of least resistance water inside a tree is a much better conductor than air 100,000 volts 50,000 degrees Sap boils and cells explode

lightning Damage that appears on one side Most trees survive Most damage when scar on both sides of trunk Lightning scar open to insects and disease Predisposed

lightning side flash, or jump, to another tree or structure

lightning exits through roots and dissipates into soil a person standing with feet apart may have deadly flow go through them Travel through irrigation wire

lightning do not prune or fertilize maintain cultural care Soil irrigation

lightning Lightning protection provides alternate route outside of tree Air terminal is at top of tree to intercept lightning

lightning Copper cable is the main conductor connected to air terminal and attached to tree at regular intervals

lightning Ground terminal connect to ground via ground rod or plate underground portion in a 8” trench
