Plain Language Summary
The hemlock woolly adelgid (HWA) is an aphid-like invasive pest from Asia that threatens hemlock survival in the eastern United States and more recently in eastern Canada. Hemlock is an important tree species because it is slow-growing and long-lived, with large canopies that create unique habitat that many plants and animals rely on. Hemlock are also very important to recreationalist and homeowners who enjoy and admire the unique environment that hemlock provide. The aim of this report is to outline the components for a HWA management plan in all eastern provinces that have hemlock at risk to HWA (i.e. Ontario, Quebec, New Brunswick, Nova Scotia, and Prince Edward Island). First, we summarize the risks and potential impacts associated with HWA in eastern Canada. We then outline potential components of an HWA management plan in Canada by summarizing the research and management tactics already explored and implemented in the eastern United States.
