Active Management of Hemlock Woolly Adelgid in Kejimkujik National Park and National Historic Site

In 2021, Kejimkujik National Park and National Historic Site (Kejimkujik) initiated a pilot project for the active management of Hemlock Woolly Adelgid (HWA). A detailed impact assessment was completed to assess the impacts of the project. Parks Canada issued a notice of determination under the Impact Assessment Act, indicating that the project was not likely to cause significant adverse environmental effects. Kejimkujik is proposing an amendment to the 2021 detailed impact assessment to assess the impacts of an updated integrated pest management (IPM) strategy that represents a modification to the previously assessed project scope. The updated IPM proposes the introduction of biocontrol agents, new chemicals, and a new pesticide application method. The Mi'kmaq of Nova Scotia will continue to play an active role in the co-management of planning and implementation of the strategy to protect key hemlock stands in Kejimkujik. Valued components to be assessed include: Eastern hemlock forests, non-target invertebrates, amphibians, forest birds, mycorrhizal networks, visitor access and enjoyment, and health of the Mi'kmaq.
