In related news: a call for formal Buy Canadian procurement policy; Northeast loggers are adjusting to Finch Paper’s decision to stop producing pulp; and Japan’s housing starts rose for a fourth consecutive month. Meanwhile: BC Wood’s Global Buyers Mission is less than two weeks away; the Independent Lumber Manufacturers’ Association asks “Where’s The Fibre?” ahead of its Osoyoos convention; Northern Innovation Network is offering support to BC workers affected by forestry’s downturn; and the CelCo Conference’s early-bird deadline is today.
In Forestry news: an injunction aimed at preventing logging protests in BC’s Walbran Valley has been extended; BC’s forestry critic is calling for increased salvage of wildfire-damaged timber; scientists are breeding disease-resistant American elms; and funding uncertainty is threatening research in Pacific Northwest experimental forests. Meanwhile: UBC is helping forest-dependent communities explore bioenergy opportunities; new research suggests satellite observations may underestimate forest carbon accumulation; Washington’s Little Giant Fire needs more resources; crews make progress on Montana’s largest fire, and the wildfire in California’s Big Sur region has forced evacuations.
Finally, US tariffs could make toilet paper more expensive — and less soft.

The US and Canada appear no closer to resolving their ongoing trade dispute. Here are five charts to help break it all down.
Osoyoos, British Columbia — September 21–22, 2026 Every industry has its acronyms. Few, however, land quite like the one the Independent Lumber Manufacturers’ Association (ILMA) has chosen for its 2026 Annual Convention: WTF — Where’s The Fibre? It’s a cheeky title for a serious question. Fibre availability — the raw material that keeps sawmills running, communities employed, and Canada’s forest sector competitive — has become one of the defining challenges facing the industry. ILMA’s answer is to lean into the tension rather than tiptoe around it, gathering the people who can actually do something about the problem for two days of conversation, deal-making, and, yes, a little golf. The ILMA Annual Convention has built a reputation as one of Canada’s premier forestry networking events, and this year’s edition returns to Spirit Ridge Resort in Osoyoos, located on the traditional territory of the Osoyoos Indian Band. The ILMA’s convention is intentionally curated — bringing together company owners and senior executives from across the sector alongside government representatives, First Nations leaders, suppliers, consultants, and forestry professionals.
Two weeks until the 23rd Annual Global Buyers Mission in Whistler! At a time when trade barriers, transportation constraints, and rising operating costs are influencing how businesses plan and source, strong supplier–buyer relationships matter more than ever. GBM brings B.C.’s value-added wood manufacturers together with pre-qualified international buyers, distributors, and specifiers. From targeted B2B meetings and conversations on the tradeshow floor to networking receptions including the Women’s Networking Event, WoodTALKS seminars, and a few memorable Whistler moments along the way, GBM is designed to create connections that last well beyond the event. See you in Whistler, September 10-12!
As the dust settles in this tit-for-tat tariff row, what will be affected most on both sides of the border? …Construction materials such as steel, aluminium as well as lumber wood have had tariffs in place before the latest escalation, though Canada has now matched US rates on the metals at 50%. Carney has also imposed import taxes on several US wood products, such as plywood, and even screws used to fix timber together. That means building firms that import such materials will face higher costs and may choose to pass those on through higher prices – pushing up the cost of homes, for example. The Forest Products Association of Canada says tariffs would “raise costs on both sides of the border”, while on the US side, Bill Owens, chairman of the National Association of Home Builders (NAHB) urged Trump to make building materials exempt from his tariff agenda due to an “ongoing housing affordability crisis”.
Japan’s housing starts increased 8.2% year-on-year in July 2026, slowing significantly from an 18.6% surge in the previous month. Still, the latest reading marked the fourth consecutive month of growth, surpassing market expectations of 7.9% growth. Owner-occupied homes rose just 0.4% (vs 15.7% in June), while rental housing growth eased markedly (10.0% vs 24.6%). In the meantime, built-for-sale homes continued to grow solidly (14.6% vs 14.2%). At the same time, starts of two-by-four homes fell further (-8.5% vs -7.4%), while prefabricated housing starts dropped 6.9%, reversing a 13.7% gain in June.
Certain forces affecting the built environment are beyond human control. …At the same time, increasingly stringent fire- and life-safety requirements have raised expectations for structural systems performing under multiple hazard conditions. For decades, steel and concrete have been the default materials for meeting these demands. However, in recent years, timber construction has emerged as a viable engineered system capable of meeting prescribed wind-load criteria and code-required fire-resistance standards, offering construction professionals a viable solution for mitigating risk and protecting both buildings and occupants. …Heavy timber and mass timber can withstand extreme wind and fire through a combination of material properties and engineered design. Timber’s ductility allows it to absorb and distribute wind forces, while high-wind connectors, hold-downs, and continuous load paths help resist uplift and lateral loads during hurricanes. …Code-recognized fire-resistance design, appropriate member sizing, tested assemblies, and protective materials allow timber systems to meet rigorous life-safety requirements. 
With the US imposing new tariffs on select Canadian exports, North Carolina State University experts warn that the escalating trade war could raise the price and reduce the quality of toilet paper and other tissue products. …Canadian NBSK is a critical raw material in global tissue manufacturing, accounting for roughly 15% to 30% of the fiber blend in premium bath tissue products and 50% to 65% in premium paper kitchen towels. Brazilian eucalyptus fiber makes up the remaining share. Gonzalez said the 50% tariff on Canadian NBSK could raise manufacturing costs for premium toilet tissue by 11% to 20%, while costs for premium paper kitchen towels could increase by 31% to 38%. …“If tissue producers choose to switch to Southern Bleached Softwood Kraft, the softness of premium tissue products will be compromised,” Jameel said. On the other hand, Gonzalez said the tariffs could create an opportunity to use more local fibers for tissue manufacturing, though they are less soft than northern softwood.
Forestry critic and B.C. Conservative MLA for Kamloops-North Thompson Ward Stamer wants to see the province salvage more wildfire-burned wood faster. He said that only about 5% of burned wood is logged on average in B.C. following a wildfire — a number he’s prefer to see rise to 25%. The former logger said he also wants to see cutting license issued faster, noting most burned trees are useless if not harvested within two years. …Stamer said once a trees dies, it begins deteriorating and each species does so at different rates. He said most burned trees that aren’t harvested within two years may only be good for low value chips, as opposed to other products such as plywood, veneer and saw logs. …Forestry Minister Ravi Parmar said the salvage rate is closer to eight to 10%. Parmar said the province is always trying to increase its salvage rate.
For decades, mature forests have been treated as if their ability to store additional carbon gradually fades toward a biological ceiling. Once trees fill the available space and their canopies close, conventional satellite measurements often suggest that forest biomass changes very little. A new analysis, however, indicates that this apparent stability may be partly an illusion created by the way satellites observe forests. Across the conterminous United States, mature forests continue to accumulate carbon over large areas, but much of that growth is being missed by current satellite-derived biomass estimates. …The researchers compared several independent ways of detecting forest change, including satellite-derived biomass estimates, lidar observations, forest inventories and ecosystem models. …The contrast between the measurements was striking. Satellite estimates indicated that biomass in mature forests had undergone nearly neutral change over recent decades, implying little overall gain or loss. Forest inventories, by comparison, estimated that mature forests were accumulating about 102 teragrams of carbon each year.
