Diseases
Forest pests and disease have seriously harmed the environment and have imposed significant cost to the U.S. economy. Exotic pests and pathogens, such as the chestnut blight, Dutch elm disease, and beech bark disease have had a profound effect on Eastern forests.
Management of these pests and diseases has been impacted by a variety of factors such as forest fragmentation, increasing human population, and the expansion of invasive species.
Prompt identification and treatment of forest diseases often means the difference between losing or saving a valuable forest stand.
The Forest Threat Summary Viewer will provide you with a one page summary that includes images, distribution maps, forestry contacts, and links to more information about forest diseases. To learn about the Forest Threat Summary Viewer and more advanced tools, see Data and Tools.
