It’s an all-too-familiar scenario to foresters: A pest is introduced into another part of the range and slowly works its way to a forest near you. So it goes with the hemlock woolly adelgid (HWA), which was introduced into eastern North America over 70 years ago. HWA has not yet arrived in Wisconsin, but we learn from the research and field experience of our colleagues in the East. Are there silvicultural approaches that can make hemlock trees and stands more resilient, along with other integrated pest management approaches? On this episode of SilviCast we discuss these approaches with Bud Mayfield, research entomologist with the U.S. Forest Service Southern Research Station and Robert Jetton, associate professor at North Carolina State University.
