Spruce budworm is considered the most damaging native insect to Canada's coniferous forest. Case in point: the stretches of Gros Morne National Park now full of damaged and dying trees. The park is the epicentre of Newfoundland's budworm outbreak, and also a giant experiment of sorts on how these can be controlled (or not) in the future. Head into the forest for the science, concern and wonder of it all in this episode, produced by Lindsay Bird.
