The hemlock woolly adelgid, an insect that measures less than one millimetre as an adult, is wreaking havoc on hemlocks in eastern North America, including in Nova Scotia. Parks Canada wants to ward off more damage by treating some trees in Kejimkujik with insecticide and by changing the makeup of the forest in the park's main campground, Jeremy's Bay. Hemlock woolly adelgids are shown on hemlock tree needles via a microscope in this October 2016 file photo. There are no native predators of hemlock woolly adelgid in eastern North America, as it is an invasive species. Insect likely to thrive without treatmentDespite the park's management plan, the vast majority of Kejimkujik's hemlock trees will not be protected against the adelgid.
