Management Strategies for Eastern Forests Threatened by Hemlock Woolly Adelgid
The presentation discusses biological and management issues associated with hemlock woolly adelgid (HWA) invasion in hemlock forests. The topics covered provide background for landowners and managers to make informed decisions about the future of the hemlock resource under the threat of HWA. We cover financial factors (what timber value will be lost), HWA biology and life history, eastern hemlock ecology and silvics, effects of hemlock mortality on wildlife habitat, probability of infestation, stand vulnerability factors, and silvicultural and management alternatives.
