Description

The use of Dutch elm disease-resistant elms as a common replacement tree in municipal planting schedules has amassed a large population of these trees in many cities throughout the eastern half of the United States. Reports from practitioners have suggested that this population is vulnerable to catastrophic losses due to severe canopy failures during wind-loading events and that American elm (Ulmus americana) selections 'Princeton' and 'Valley Forge' are chronically among the most damaged, which is a combination of poor structure and sheer numbers in the landscape. In this study, tree failures resulting from two storms occurring in 2015 (28 July) and 2016 (05 July) in Saint Paul, Minnesota, were examined. In both cases, young American elms were failing due to excessive canopy damage at a rate of two to three times the failure rates of other tree species in the same landscapes.
