How will the boreal forest react to climate change? How will higher carbon dioxide (CO2) concentrations and warmer temperatures affect the growth and productivity of forest species? Answering these questions is a complex exercise. Over the years, researchers with the Canadian Forest Service (CFS) have been able to provide some answers, especially pertaining to black spruce and white spruce.

Plain Language Summary

This publication reports on studies conducted in the boreal forest on the reaction of black and white spruce trees to increases in CO2 concentrations and temperature.

Should these increases occur, the growing season for black spruce would be shorter, there would be an increase in stand productivity, and a small increase in tree yield in the short term. In the case of white spruce, higher atmospheric temperatures would result in a slight increase in tree yield in the short term. The reaction of white and black spruce trees to new environmental conditions depends on the genetic diversity of the species’ populations and on their origin.

Branching Out is a series of plain language fact sheets describing Laurentian Forestry Centre research projects.
