ONTARIO — An invasive insect that can wipe out hemlock forests has been discovered in the Cobourg area — and researchers suspect they may have been there for years, unnoticed. The hemlock woolly adelgid was confirmed by scientists and students from Natural Resources Canada’s Canadian Forest Service who were collecting data in the area as part of an inventory of the province’s hemlock trees. …“Hemlock woolly adelgid (HWA) is a serious invasive forest pest, originally from Japan, that has killed hemlock forests across the eastern United States since the 1970s”. The insect was first found in Toronto in 2012. …Cobourg’s hemlock forests stretch continuously to the Kawartha Lakes and Muskoka regions, meaning landowners and cottagers risk losing large stands of old-growth hemlock trees.
