Emerald Ash Borer damage areas by damage type are displayed within the insect and disease survey areas. The 2011 insect and disease survey is displayed by default. A map service on the www depicting a compilation of forest insect, disease and abiotic damage mapped on forested areas in the United States that provides a single, consistent data source to facilitate national and multi-regional reporting for Forest Health Monitoring and Forest Health Protection. All reported emerald ash borer damage types are shown within the insect and disease survey areas from 2007 to 2011.
The emerald ash borer (EAB) poses a tremendous threat to ash forest habitats across the upper Great Lakes. Of particular concern is the impact EAB will have on the ecology and functioning of black ash ( Fraxinus nigra) forested wetlands, which cover over 500,000 ha in Michigan, Minnesota, and Wisconsin and represent the region’s most common ash forest habitat. Black ash often occurs in relatively pure stands on poorly drained sites where it serves as a foundation species exerting a strong control over ecosystem structure and functioning. Correspondingly, extirpation of this species by EAB could have negative cascading effects, including dramatic rises in water tables and shifts in vegetation composition towards...
