Overview info and resource documents for the hemlock woolly adelgid, originally from Asia, which was first discovered in the eastern U.S. in the 1950’s. It has since spread throughout the range of hemlock in the East, and caused extensive mortality of mature hemlock – especially in the Appalachian Mountains.

The University of North Georgia (UNG) Ecological Protection Lab (formerly the Beetle Lab) has led in regional efforts to protect the Eastern Hemlock from the invasive Wooly Adelgid by initiating biological control efforts through the rearing and release of predatory beetles to reduce adelgid numbers and impacts.

The Young Harris College (YHC) Hemlock Proiect is a volunteer effort of community members and students to help raise Sasajiscymnus tsugae, a tiny ladybird beetle that is one of the few natural predators of the HWA. The organization works in conjunction with the Forest Service and GFC to decide where to release the adult beetles.

Since 2014, LLLT has treated 7,500 Hemlocks against the Hemlock Wooly Adelgid, and the core preserve serves as a State of Georgia research site for chemical and biologic controls.

Forests for the Bay: Keeping woodlands healthy.

The Tree Campus Higher Education® program helps colleges and universities around the country establish and sustain healthy community forests.

Found in the outer bark areas of living and healthy trees, Hypoxylon are normally of little consequence. However, the fungi can severely injure or kill trees that have been weakened by factors such as drought, root disease, mechanical injury, logging or construction activities. T

Healthy roots are the foundation for a long, beautiful relationship with your trees. A girdling root problem starts very early in a tree’s development and can cut short a plant’s life.
