    • Wrap tree trunks with 24″ (or greater) aluminum flashing at least 6 feet off the ground to prevent climbing (see photo at right by Stephen M. Vantassel). Flashing is used on trunks to reduce climbing access. Place 1/4-inch shives between tree and flashing to prevent mold from developing.
    • Wrap 3 rows of porcupine wire, spaced with tines 2 inches apart, to help prevent squirrels from climbing. Be sure the porcupine wire is at least 8 feet off the ground to prevent people from accidental impalement.
