To introduce landowners and land managers to the various options available to protect their hemlocks, the Hemlock Restoration Initiative, in partnership with the Highlands-Cashiers Land Trust and the Cashiers Historical Society, will be giving a hemlock woolly adelgid (HWA) management workshop at the Zachary Tolbert House in Cashiers, NC.

Workshop Schedule

Thursday, November 11, 7–8:30 pm: Orientation and discussion of background on hemlocks, HWA, and IPM (online)

Friday, November 12, 9 am–4 pm: Hands-on chemical treatment training (in-person)

Workshop Description

An online presentation will be provided the evening before the field session covering the background information relevant to the hands-on training. Topics covered include the ecological importance and value of hemlocks in urban and community forests, the biology of HWA and other hemlock pests, integrated pest management strategies, and the role of the Hemlock Restoration Initiative in North Carolina’s various hemlock management efforts. On Thursday, November 11 from 7 to 8:30 pm, we will hold a live Zoom meeting where we will cover logistics for the field session and answer questions about the material covered in the presentation. The online portion and orientation are required to participate in the field portion of the workshop.

From 9 am to 4 pm on Friday, November 12, we will use the trees present at the workshop site to learn and practice a variety of methods to treat hemlocks available to all landowners in North Carolina. Participants will receive in-person instruction and hands-on practice. We will cover the details of chemical treatment, including how to identify hemlock trees; assess individual tree health and infestation severity; select, mix, and safely apply products; as well as when to seek help from a tree care professional.
