    Dynamic Tree Sway Response after Storm Resiliency Management


    Acclimation of trees to wind is a well-known phenomenon illustrated by open grown and most edge trees. However, tree and forest management intended to enhance the acclimation response of trees is rarely done. In this session I present prescriptions which combine approaches from silviculture and arboriculture intended to enhance the storm resilience of trees near power lines. This research and development is part of the larger STORMWISE initiative recently originated at the University of Connecticut.  I will also include preliminary results from an experiment to quantify the long-term acclimation of trees after treatment with monitoring the dynamic sway response of 13 trees along and near a power line corridor on the UCONN forest.   Sway frequency and spatial analysis of sway patterns document wind sway dynamics before and after treatment and will be used to document changes attributable to acclimation over time. 


    Mark Rudnicki is an Associate Professor at the University of Connecticut and has researched both the short term and long term effects of wind on trees for the past 15 years. He has developed field techniques that monitor and reconstruct tree stem motion for groups of trees and 3-D techniques that capture individual branch dynamics. He contends that by understanding how trees survive and acclimate to complex wind forces, we can develop management strategies to increase their storm resilience.
