Trees and Ice Storms -- The Development of Ice Storm Resistant Urban Populations

This article provides brief descriptions of how ice storms occur and some history behind major ice storms in the early 1900's. The article states that weight loading of branches can be increased by 30 times or greater and strong winds substantially increase the potential for damage. The primary emphasis of the article pertains to tree features that influence ice storm susceptibility. These include bark, dead and decaying branches, broad crowns, imbalanced crowns and location. Excurrent vs. decurrent branching forms are discussed in terms of ice damage susceptibility. A brief, but well done list of susceptibility of tree species for urban areas is included as well as suggestions on management and care to reduce damage on trees and costs associated with such events.
