Title: Trees, Sites & Ice Storms: Attributes Leading to Tree Damage, Failure, & Mortality
Description: Ice storm events happen periodically 2 - 25 years apart in most of the Eastern portion of North America. Figure 1 shows the distribution of ice storms by month, with the peak coming in February and March when warm fronts are moving over cold surface temperatures. Even places in the deep South are not immune to occasional icing events. In some locations, major ice storms (>$1 million damages) generate catastrophic tree damage every 4 to 100 years apart. Figure 2 demonstrates differences in damage classes for one major ice storm in two locations along its path – Maine and Quebec. Major ice storm impacts on trees have been carefully studied for almost 100 years. This publication will look at more recent studies for what makes trees susceptible to damage and failures.
