Even small injuries can have serious long-term consequences for a tree. Carving initials in the
bark; nailing a sign on the trunk; topping the tree, using wire ties with supporting stakes;
and leaving ties around limbs too long all can damage a tree. Hanging a swing from a limb,
nicking the bark with string trimmer or lawnmower all cause wounds that allow insects and
disease spores to enter the tree. Gradually weakened, any tree is vulnerable to storm damage.
