Canada’s forests are immense, masking practically 350 million hectares and holding nearly 9% of the world’s forested land. They’re central to the nation’s id, economic system, and local weather profile. For many years, forestry has supplied jobs and exports whereas sustaining comparatively secure forest cowl, however the local weather and biodiversity math has shifted. Canada’s forests are now not a constant carbon sink. In lots of latest years they’ve been a web carbon supply because of a mix of wildfires, insect outbreaks, and the way in which harvesting is finished. Which means any future enlargement of a forest merchandise sector, together with the much-discussed mass timber business, needs to be contingent on making forestry really sustainable.

In my prolonged collection on mass timber in Canada, sustainable forestry was given too little consideration, one thing commenters have been bringing to my consideration. This text, and the analysis I did to know the area, corrects that, though it turned clear to me that a complete collection of articles can be required to greater than evenly deal with it. Along with this text, I’ve added it as a bit in my report on mass timber in Canada.
The numbers are stark. Canada harvests about 130 million cubic meters of wooden annually, primarily softwoods from the boreal and temperate zones. That represents about 0.2% of the forest space yearly, which sounds small, however when mixed with pure disturbance the footprint is far bigger. Wildfires alone common 2 million hectares burned yearly, with outlier years like 2023 seeing greater than 15 million hectares burned. Bugs such because the mountain pine beetle and spruce budworm add additional mortality. These disturbances take away timber that fashions as soon as counted as accessible for harvest. If forest administration doesn’t alter for this, then harvest ranges danger overshooting what ecosystems can assist whereas sustaining biodiversity and carbon shares.
From a local weather perspective, harvesting mature forests creates an instantaneous pulse of emissions. Carbon saved in trunks, branches, roots, and soils is launched over years and a long time. Solely a portion of that carbon results in long-lived merchandise. A major share is in paper, packaging, or bioenergy, the place it returns to the environment rapidly. Reforestation finally reabsorbs carbon, however the lag time may be many a long time. Within the context of 2030 and 2050 local weather targets, that lag issues. A cubic meter of wooden utilized in a cross laminated timber panel that sits in a constructing for 80 years contributes to a local weather resolution. The identical cubic meter burned in a pellet plant in Europe contributes to near-term emissions on the worst potential time.
This is the reason the observe of pelletizing Canadian wooden and transport it abroad has to cease. Canada exported roughly 3 million tons of wooden pellets in 2023. That’s wooden that might have been saved in buildings for many years, displacing concrete and metal. As an alternative, it was transformed into power with carbon emissions counted as zero by importing nations although the atmospheric impression is actual. The concept forest bioenergy is carbon impartial has been extensively discredited. Persevering with to chop major or secondary forests for pellets undermines each Canada’s local weather commitments and the credibility of its forest sector.
Biodiversity indicators inform the same story. Woodland caribou are the sign species for boreal sustainability. They want giant tracts of undisturbed forest, at the very least 65% of their ranges left intact. Most herds in managed forest zones fall properly beneath this threshold, and plenty of populations are in decline. Outdated progress temperate rainforests in British Columbia have been lowered to fragments, with over 95% of the most efficient stands already gone. These ecosystems retailer enormous quantities of carbon and assist distinctive species. Logging the remnants can’t be known as sustainable. The lesson is obvious: if harvest plus disturbance pushes landscapes exterior their pure vary of variation, species decline and ecosystems unravel. Sustainable yield has to imply greater than timber volumes balancing regrowth. It should imply that habitat construction, species composition, and age-class distributions stay inside wholesome bounds.
A mass timber business is determined by long-term credibility. If the wooden used for panels and beams comes from degraded ecosystems or from fiber that ought to have been left to get better, then the local weather case for mass timber collapses. The pathway ahead is to make forestry appropriate with each local weather objectives and biodiversity safety. That requires a shift from high-volume commodity extraction towards increased worth per cubic meter. Canada’s forestry has traditionally been about maximizing quantity. A cubic meter became pulp has a low worth and a brief life. The identical cubic meter became a cross laminated timber panel or a prefabricated module can retailer carbon for a lot of a long time and displace supplies which have a lot increased emissions profiles.
There’s a clear industrial logic to this shift. Worth per cubic meter in pulp is perhaps tens of {dollars}. In a completed module it may be 1000’s. The workforce wanted to provide engineered merchandise and modules is bigger per unit of wooden than the workforce for commodity lumber. Meaning extra jobs and extra stability for communities without having to chop extra forest. It additionally aligns with international demand, as nations in every single place search low-carbon building options. Canada may very well be exporting prefabricated buildings slightly than uncooked logs or pellets.
Indigenous partnership is a vital a part of this future. A lot of the forested land is on conventional territories. Sustainable forestry has to imply consent and co-governance with Indigenous nations. This ensures not solely respect for rights but in addition integration of data that may enhance ecosystem stewardship. Whereas this text focuses on local weather and biodiversity, you will need to acknowledge that legitimacy and long-term success in forestry require Indigenous management.
International comparisons are instructive. Finland and Sweden present that forests may be extremely productive below intensive administration, however their biodiversity deficits are important and now require correction. Germany reveals how close-to-nature silviculture can maintain ecological values, although with decrease yields. New Zealand demonstrates a plantation mannequin that provides giant volumes from small areas whereas sparing native forests, however with dangers from monocultures and erosion. Uruguay reveals how coverage can create a plantation business from nearly nothing, however with trade-offs for water and grassland ecosystems. Canada nonetheless has giant intact forests. That is a bonus most different industrial nations have already misplaced. The problem is to keep away from following the identical path of over-intensification and as a substitute leapfrog to a mannequin that delivers increased worth from decrease quantity whereas defending intact ecosystems.
The outlines of such a mannequin are seen. Annual harvest ought to stay round 0.2% of forest space or much less, with a declining share from major and old-growth forests. Nearly all of harvested carbon ought to find yourself in long-lived merchandise, not in short-lived paper or pellets. Carbon accounting have to be clear, with full recognition of logging emissions and regrowth lags. Harvest plans should incorporate biodiversity thresholds, such because the 65% undisturbed requirement for caribou. Protected areas and Indigenous Protected and Conserved Areas must increase to cowl essentially the most delicate ecosystems.
A roadmap to this future would start with quick moratoria on essentially the most at-risk old-growth and important caribou ranges, elimination of subsidies or assist for pellet exports, and focused funding in mass timber factories and provide chains. Over the following decade, allowable cuts needs to be revised downward in areas the place pure disturbances are rising, and constructing codes and insurance coverage frameworks needs to be aligned to encourage mass timber building. By mid-century, Canada’s forest sector may very well be smaller when it comes to cubic meters harvested however bigger when it comes to jobs, exports, and local weather advantages.
Canada has the chance to align its forestry and its mass timber business with a sustainable future. The circumstances are clear: cease slicing timber for power pellets, shift to increased worth per cubic meter, and embed local weather and biodiversity thresholds into each plan. Completed proper, this is able to permit Canada to export not solely wooden merchandise but in addition a mannequin of find out how to handle huge forests responsibly in a century outlined by local weather and ecological limits.
