    Restoration of storm damaged trees


    When urban trees are injured in severe storm events, they often respond to this damage by sprouting new branches, often from latent buds. Sprouts replace the branches and foliage lost when the tree was damaged, and may also assist in reducing the spread of discoloration and decay following injury. Although it is believed that at least some sprouts are weaker than normal branches, little empirical evidence exists to support this. Many of the surviving shade trees will require restoration pruning that incorporates sprouting branches as part of the new crown. Arborists have few research-based guidelines on how to craft strong trees from storm-damaged sprouting crowns. Many sprouts originate from ends of damaged branches or heading cuts or grow upright from horizontal limbs, and are necessary for damaged trees to begin restoration. Understanding the strength of attachment of these sprouts  is essential to elevate our current understanding of restoration pruning. This presentation will cover current recommendations for the care of storm damaged trees, with a focus on crown restoration treatments. Recently completed and ongoing research investigating crown restoration treatments, with support from the TREE Fund, will also be presented.

    Jason "Jake" Miesbauer is a Research Scientist at The Morton Arboretum. His research focuses on factors that predispose trees to storm damage and cultural practices to reduce susceptibility to storm damage. He has collaborated with scientists from multiple disciplines to better understand forces that act on trees. Jake earned his Ph.D. from the University of Florida and his Bachelor of Science degree from University of Wisconsin – Stevens Point majoring in urban forestry and business administration. Jake is an ISA Certified Arborist with several years experience in the tree care industry as a practicing arborist and plant health care technician. He has been active in outreach to the tree care industry and has presented on topics that include: tree biomechanics, restoration of storm damaged trees, proper pruning methods, tree planting and stabilization, and safety in arboriculture.
