This project focuses on the Eastern United States of America, from Maine to Georgia where there is a current distribution of the invasive species Hemlock Woolly Adelgid, as well as along the range of Eastern Hemlock in Eastern Canada, specifically Ontario, Quebec, New Brunswick, and Nova Scotia. Figure 1 shows the study area, which is a total of 2745 million km2. Although Hemlock Woolly Adelgid is currently well-managed in Canada, there is still a risk of potential HWA spread due to these provinces' proximity to the border and relatively high abundance of Eastern Hemlock groves in the south of the provinces. There are 10660 km2 of hemlock in Ontario, 794 km2 in Quebec, 112 km2 in Nova Scotia and 976km2 in New Brunswick (Natural Resources Canada 2018). This study area is significant to the research question because the project will be analyzing the risk of spread from the HWA's current distribution in the Eastern States into these Canadian provinces.
