The spruce budworm, (Choristoneura fumiferana – SBW), a native insect found throughout Canada, is considered the most serious pest of fir and spruce forests in North America. It has been the subject of research for more than half a century, but questions remain: for example, with climate change, will the SBW change its diet or its distribution area? Canadian Forest Service (CFS) researchers have examined this issue.
Plain Language Summary
This publication reports on changes to spruce budworm (SBW) diet and range caused by climate change.
Historically, SBW causes greater damage to balsam fir stands. However, with milder temperatures, the SBW range could shift northward. This northward movement could have consequences for the nutrient cycle of the black spruce forest ecosystem.
Branching Out is a series of plain language fact sheets describing Laurentian Forestry Centre research projects.
