An exotic pest threat to eastern hemlock: an initiative for management of hemlock woolly adelgid

Abstract

Hemlock woolly adelgid (HWA) is the greatest threat to the health and sustainability of hemlock in eastern North America. The potential ecological impacts of this exotic insect pest can be compared to those of gypsy moth, Dutch elm disease, and chestnut blight. The USDA Forest Service, with the support and cooperation of the National Association of State Foresters and the National Plant Board, is proposing an expanded program to develop and implement management strategies to reduce the impact and slow the spread of HWA. This 5-year initiative calls for expanded research and technology development combined with accelerated management efforts implementing existing and newly developed control techniques. This document briefly describes this initiative's goals and funding requirements.
