Title: Dutch Elm Disease (DED) and the American Elm (Pest Alert)
Author: USDA Forest Service

Abstract: For decades the American elm was one of our most treasured trees, gracing streets and parks of many cities with beautiful form and dense foliage. The American elm was particularly well suited to urban sites because it grows quickly, is long-lived, and is tolerant of compacted soils and air pollution. However, in most communities Dutch elm disease (DED) killed a significant number of our American elms and threatens those that remain. By wisely choosing how we manage our urban elm resource, we can reduce the risk of remaining elms becoming diseased.
