Biocontrol for Nova Scotia Hemlock Infested with Hemlock Woolly Adelgid

The Medway Community Forest Co-op is partnering with the province to launch a hemlock conservation program aimed at protecting Nova Scotia’s precious old growth hemlock forests from the invasive Hemlock Woolly Adelgid (HWA). MCFC will be forming “Strike Teams” to execute targeted pesticide application in old growth hemlock stands and protected wilderness areas across southwest Nova Scotia as well as establishing the “Hemlock Heroes” volunteer stewardship program to engage volunteers in assisting with HWA treatments.

Kejimkujik National Park and National Historic Site (KNPNHS) is managing a Hemlock Woolly Adelgid (HWA) infestation using a combination of silvicultural and chemical control methods, which include the use of neonicotinoids. In 2021, a pilot project for the active management of Hemlock Woolly Adelgid was initiated. A detailed impact assessment was completed in the same year to assess the impacts of the project. A five-year project has been developed hat will increase Parks Canada’s understanding of HWA, enhance the resiliency of hemlock forests infested with HWA, slow the spread of HWA within and beyond Kejimkujik, and limit the impact of HWA on Kejimkujik’s old-growth forests.
