Following Tree Frog News’ November 7 op-ed, “Rigged by Design? How Method and Policy Keep U.S. Lumber Duties High”, the US Lumber Coalition responded (Understanding Why Duties Persist — Not Because of Arbitrary Math, But Because of Past and Ongoing Harm) noting that the Department of Commerce did not use “zeroing” in its latest anti-dumping calculation. The note below clarifies what Commerce actually applied and what remains unresolved.
Following publication, the US Lumber Coalition pointed out that the Department of Commerce did not use “zeroing” in its latest anti-dumping calculation. In reviewing the record, Tree Frog News found that Commerce applied a differential-pricing framework, which uses statistical tests to determine comparison methods.¹ However, a 2020 WTO panel found that this framework could produce mathematically similar distortions to zeroing — in effect, “replicating the problem without using the name.”² but because the most recent review record is largely redacted and the WTO Appellate Body remains inactive, there has been no external review of how this method performed in the most recent review.
The more important question, then, is whether the procedural change has addressed the sources of bias identified in past WTO rulings — specifically in how Commerce calculates anti-dumping margins, measures subsidies, and selects its review periods — which continue to produce duty levels that appear inconsistent with actual market conditions. Tree Frog News will continue to report as new information emerges.


President Donald Trump has yet to follow through on his threat to impose an additional 10 percent tariff on Canadian imports, four weeks after he halted “all trade negotiations” over an anti-tariff ad the province of Ontario ran. Trump’s announcement had Canadian exporters preparing for a worst-case scenario: a sweeping levy layered on top of existing double-digit duties. …The White House did not say whether it still plans to impose the tariff when asked for comment. But a separate US official suggested the Trump administration had opted to hold off on additional duties — which would have sent tariffs on Canadian goods to 45% — and instead continue to dangle the threat as the two sides gear up for future talks. “The Canadians know what’s on the table,” said the official. Volpe said a personal intervention by Carney in Asia last month may have helped matters, too.
Canada’s forestry industry plans to divert a significant share of its wood exports from the US to new international markets. …The aim to send some 1bn board feet to alternative markets underscores how Trump’s tariffs are starting to reshape some global supply chains, although tensions between the US and Canada over wood exports have simmered for more than half a century. …“The US simply needs to fact-check better before they end up with a large shortage of lumber that may cause further housing shortages,” said Rick Doman, chair of FII BC. …Zoltan van Heyningen for the US Lumber Coalition said the American timber industry could replace 1bn board feet of Canadian imports “without batting an eyelid”. …The NAHB says at just 64% of capacity it “will take years” for US domestic lumber production to expand to meet industry demands. …Mike McDonald, a UK-based consultant, acknowledged it would take time to establish confidence among European consumers.

KINGSPORT, Tennessee — About 300 gallons of waste leaked from Domtar’s mill site to Domtar Park, according to Tennessee Department of Environment and Conservation documents. Of the 300 gallons of waste, which included liquids and solids, about 150 gallons were recovered. The mill’s 25-acre lagoon was lowered four to six inches as a precautionary measure in response to the leak, Domtar told the Times News. In its letter to TDEC, Domtar said no detrimental effects were observed to the property or the environment due to the “organic nature” of the lagoon’s contents. Domtar also said it believed the waste found at Domtar Park was “partially” treated through its wastewater treatment process. “The leak did not reach waters of the state and Domtar representatives indicated mitigation was taking place. No further action was taken by the department,” said TDEC spokesperson Jennifer Donnals in a statement to Six Rivers Media.


STEVENS POINT, Wisconsin – USDA Rural Development Wisconsin State Director Andrew Iverson announced the Timber Professionals Cooperative Enterprises (TPCE) will use a Rural Development loan of $800,000 to re-open and expand the former Hoffman Wood Fiber sawmill in Shawano County. This investment is through the Timber Production Expansion Guaranteed Loan Program (TPEP). TPCE will use guaranteed loan funds to purchase over 49 acres of real estate and equipment. The equipment will allow TCPE to improve the efficiency of manufacturing wood chips. The project also includes plans to expand capabilities of the site to manufacture new, higher-value products from the same raw materials. The project will create six jobs. …TPCE plans to implement a detailed process to improve productivity involving processes in the wood yard and chip mill. Installation of an automatic log feed deck will help increase production from 2,500 to 4,000 tons per month.


After four major paper and pulp mills closed in Georgia this fall, the phone at the South Georgia Sawmill began ringing nonstop. …woodsmen from Georgia were begging owner Adam Williams to buy at least some of their logs… Williams had to say no. The scene here in Georgia is being replicated in other timber markets, raising larger questions about what measures the United States could take to become more self-reliant and preserve its foundational industries. While most of the U.S. wood supply has historically been homegrown, imports have surged, particularly from Canada. … Republican Gov. Brian Kemp has assembled a task force to suss out new opportunities for Georgia wood. Georgia Tech University, for one, is at the forefront of technology that might one day refine new types of aviation fuel from trees. The state is also pioneering the use of so-called “mass timber” – cross-laminated panels of two-by-sixes that replace concrete and steel.
Nearly 40 Tennessee hardwood companies are among hundreds of U.S. hardwood industry operators calling for federal relief from tariff-induced economic hardship. Tennessee’s forestry products industry supports an estimated 85,000 jobs, according to the
An Augusta lumber mill is closing permanently. The West Fraser Timber mill is expected to shutter by the end of 2025, putting 130 employees out of jobs, the company announced. “The closure of the Augusta lumber mill is a result of challenging lumber demand, and the loss of economically viable residual outlets, which combined has compromised the mill’s long-term viability,” the company said. …West Fraser said it “expects to mitigate the impact on affected employees by providing work opportunities at other company operations, where available.” The Canadian company’s lumber mill operations closest to Augusta are in the Georgia cities of Blackshear, Dudley, and Fitzgerald, all at least 100 miles away. West Fraser also runs facilities in Cordele and in Allendale, South Carolina, that produce oriented strand board. …“The announcement is difficult news for employees, their families, suppliers, and the community,” Georgia Forestry Association’s Tim Lowrimore said.




The US Census Bureau announced the following value put in place construction statistics. …Construction spending during August 2025 was estimated at a seasonally adjusted annual rate of $2,169.5 billion, 0.2 percent (±0.7 percent) above the revised July estimate of $2,165.0 billion. The August figure is 1.6 percent (±1.5 percent) below the August 2024 estimate of $2,205.3 billion. During the first eight months of this year, construction spending amounted to $1,438.0 billion, 1.8 percent (±1.0 percent) below the $1,463.7 billion for the same period in 2024. …Spending on private construction was at a seasonally adjusted annual rate of $1,652.1 billion, 0.3 percent (±0.5 percent) above the revised July estimate of $1,647.5 billion. …In August, the estimated seasonally adjusted annual rate of public construction spending was $517.3 billion, virtually unchanged from (±1.2 percent) the revised July estimate of $517.5 billion.
The Supreme Court could decide on the legality of many of the Trump administration’s tariffs within months, but the ruling won’t impact many of the administration’s levies on imported construction materials such as lumber, steel, aluminum and copper. …Many construction materials imported into the US will remain subject to hefty tariffs regardless of how the Supreme Court rules. Some homebuilding leaders warn that home prices could increase by thousands of dollars beginning next year. …Cristian deRitis, at Moody’s Analytics, said “While importers of other building materials might experience some relief, this could be temporary. The administration may choose to expand the Section 232 tariffs as a fallback strategy if the reciprocal tariffs are invalidated,” deRitis said. …There hasn’t yet been an increase in lumber prices, but NAHB Chairman Buddy Hughes forecasted that the lumber tariffs “will create additional headwinds for an already challenged housing market by further raising construction and renovation costs.”




SALT LAKE CITY — Homeowners in high wildfire risk areas should soon expect home assessments and a new fee. HB48 Wildland Urban Interface Modifications requires the Utah Division of Forestry, Fire and State Lands to draw a high wildfire risk boundary across the state. The division will inspect homes within the boundary for fire risk, and property owners will pay a fee based on their risk and square footage, which will cover the cost of the program and lot assessments. State Wildfire Risk Reductions Programs Manager Joseph Anderson said the assessments will focus on the vegetation surrounding the home and the materials used in the structure. “The goal is to remove any vegetation or anything that could catch an ember and allow that ember to burn and catch the structure on fire,” Anderson said. The bill comes after catastrophic wildfires across the West, like the California Eaton Fire from January 2025. 
REDDING, Calif. – A groundbreaking effort is underway in Redding where 


The timber industry built around the Tongass National Forest in Alaska got a boost from the Trump administration’s latest trade deal with China. In settling part of its trade battles, China agreed to accept imports of US sawlogs for the first time since banning them in March due to worries about insect pests. The resumption of exports — effective Nov. 12 — would help companies like Alcan Forest Products in Ketchikan, which for years has sold unprocessed logs to China. The latest agreement lasts one year, said Tessa Axelson, executive director of the Alaska Forest Association. A 10% tariff on products from both countries would still apply. …Southeast Alaska’s timber industry relies heavily on the nearly 17-million-acre Tongass, although most of the forest is off-limits to logging. Federal law allows the export of unprocessed logs, a practice long banned elsewhere to protect the domestic lumber processing industry.

Oregon — Deschutes County is preparing to deploy $3.4 million for wildfire mitigation projects to reduce the likelihood of catastrophic wildfire in La Pine. The money comes from the U.S. Department of Agriculture and is part of a $200 million funding package to assist fire-prone areas across the country. Work is expected to begin in the spring on a variety of projects ranging from fuels reduction to community education, according to Lauren Street, a natural resources specialist with Deschutes County. The project is expected to continue for five years. La Pine was one of 58 recipients nationwide to benefit from community wildfire defense grants. The grants are funded by the Biden-era bipartisan infrastructure law of 2021. Elsewhere in Oregon, the Sweet Home Fire and Ambulance District is set to receive $8.7 million, the largest grant for any project in the state.


OLYMPIA — The Washington Forest Practices Board took 200,000 acres of timberland out of production, voting 7-5 to require loggers to stay farther back from streams without fish. The close vote Nov. 12 capped a contentious debate over the environmental and economic consequences of widening and lengthening riparian buffers to shade streams. Forest landowners will lose $2.8 billion in harvestable timber because of the new buffers, according to a University of Washington analysis. Ten state representatives, five Democrats and five Republicans, questioned whether the board had thoroughly examined the social costs. And the Environmental Protection Agency said the bigger buffers are not needed to meet the Clean Water Act. But the Department of Ecology championed wider and longer buffers. The buffers will keep timber harvests from warming water temperatures in most cases, according to Ecology. “Not taking action is not an option,” said Ecology Director Casey Sixkiller, a member of the forest board.
On Oct. 17 … the Flathead National Forest’s district ranger in Swan Lake proposed an emergency logging and thinning project west of Blacktail Mountain called the West Truman Project. The project proposal … was published to the Flathead National Forest’s projects website, signaling a departure from the agency’s usual strategy of notifying members of the public about planning projects by email and issuing press releases. It also came with a caveat: The West Truman Project is being analyzed under the USDA’s newly established Emergency Action Determination and, as such, is exempt from the usual layers of permitting compliance — including public comment. …Keith Hammer, leader of the Swan View Coalition, said he wasn’t surprised to see the Flathead National Forest propose a logging project with the stated purpose of reducing wildfire risk; however, he was surprised by the covert way in which they proposed it.

The Washington Forest Practices Board may vote Nov. 12 to widen and lengthen riparian buffers, taking millions of dollars worth of timber out of production. Forest landowners and the wood-products are mounting a last-ditch effort to persuade the board to not adopt what they say would be a massive taking of private property. The state Department of Ecology says wider and longer buffers would keep timber harvests from raising temperatures in non-fish bearing streams in most cases. Timber groups haven’t been in a battle this divisive since the industry, state agencies and tribes settled on seminal logging rules in 1999, Washington Forest Protection Association’s Darin Cramer said. …Studies confirmed logging raises water temperatures. The timber industry argues that even if temperatures rise, they soon go down and generally do not exceed acceptable levels. Massachusetts-based consultant Industrial Economics estimates the rule will take somewhere between 67,000 acres and 170,000 acres out of production.
Rising wildfire risk in the Pacific Northwest combined with volatile timber pricing may lower forestland values by as much as 50% and persuade property owners to harvest Douglas fir trees much earlier than planned, according to a new analysis. The optimal age to harvest Douglas fir trees — absent fire risk — would be 65 years. The study, from Oregon State University researchers, suggests that harvesting trees at 24 years would make the most economic sense under the worst-case scenarios. “Basically, under high wildfire risk that rises with stand age, every year you wait to harvest you’re rolling the dice,” said Mindy Crandall, an associate professor in the OSU College of Forestry. Co-author Andres Susaeta, an OSU forestry assistant professor, said the study was a simulation, but researchers are confident in the direction of results. Susaeta said earlier harvesting reduces both long-term timber revenue and impacts wood quality.
Policies by the Trump administration are putting communities at increased risk for wildfire because federal funding for fuels treatment work is becoming more difficult to obtain. That is the opinion of a group of policymakers and politicians who convened in Bend last week to discuss how best to manage local forests. Bend Mayor Melanie Kebler, Deschutes County Commissioner Phil Chang and State Senator Anthony Broadman — all Democrats — were among those in attendance… Members of the group said there is a lack of clarity over future treatments in the Deschutes National Forest following years of mitigation work that cleared the forest floor of fuels and thinned areas to prevent a fast-moving crown fire. …Chang said he is especially concerned with the Trump administration’s Fix our Forest Act … The bill relies mostly on logging and cattle grazing to clear fuels that cause catastrophic wildfire, but funding for prescribed burning isn’t part of the legislation.
Every year, there are thousands of landslides in Oregon. Geologists say the number is increasing due to climate change. …Swaths of the Pacific Northwest are particularly prone, thanks to a combination of mountainous landscape and heavy rainfall. “Over the last couple decades, the landslides and the surface processes and surface hazards that I’ve been working on have become much more prominent, primarily due to climate change and humans inhabiting more areas in hazardous terrain,” said Josh Roering, a professor of earth sciences at the University of Oregon. …Roering is one of the geologists involved in the newly formed Center for Land Surface Hazards (CLaSH). A $15 million NSF grant jumpstarted the center that will study landslides and other surface hazards. While CLaSH is housed in the University of Michigan, it is a collaboration with more than a dozen academic, governmental and community partners across the country.
Miles Ryan checked his harness one last time, gave an assured look to his ground crew, and started to climb. …There, balanced at the top of the forest, Ryan leaned out toward the tips of the limbs to get what he’d come for: cones. It was one of Cal Fire’s last cone samplings of the season, which usually runs from August to October across state forests and conifer species. Each cone contains anywhere from a few dozen to hundreds of precious seeds. These have become more important in recent years, as an uptick in severe wildfires and the spread of insects and diseases have led to mass deaths of pines across California forests. But there are just a few dozen professional tree climbers like Ryan trained for high-elevation seed collection in California. …Cal Fire needs to collect 55,978 bushels of cones across species and locales to fully stock its seed bank.
PROVIDENCE, R.I. — It’s one of nature’s mysteries: How can woodpeckers, the smallest of which weigh less than an ounce, drill permanent holes into massive trees using only their tiny heads? New research shows that there’s much more at play, anatomically: When a woodpecker bores into wood, it uses not only its head but its entire body, as well as its breathing. In a study published in the Journal of Experimental Biology, a team led by biologists at Brown University reveals how woodpeckers combine breathing and whole-body coordination to drill into trees with extraordinary force. “These findings expand our understanding of the links between respiration, muscle physiology and behavior to perform extreme motor feats and meet ecological challenges,” said lead author Nicholas Antonson… The team studied downy woodpeckers, the smallest species of woodpeckers in North America, which populate forested areas throughout the United States and Canada.



WASHINGTON – The U.S. Department of Agriculture directed its staff to identify grants for possible termination in the early months of the second Trump administration by searching for more than two dozen specific words and phrases related to diversity and climate change, according to documents seen by Reuters. The effort was undertaken as part of a broad campaign across federal agencies to comply with President Donald Trump’s directives to end diversity, equity and inclusion efforts and climate regulation in the federal government. Trump … has called climate change a “con job.” The documents, obtained by legal advocacy group FarmSTAND … show the breadth of that effort… The topics and terms included “climate modeling,” “climate and emission analysis,” …”carbon pricing and market mechanics,” “renewable energy modernization that does not directly benefit farmers,” “climate adaption (sic) and resilience planning” and “biodiversity and ecosystem resilience related to climate change”.
Smoke from wildfires causes a cascade of changes in the proteins in the blood of firefighters, according to a groundbreaking study by researchers from the University of Arizona School of Public Health. The researchers found 60 different changes in blood proteins in samples taken from 42 firefighters who battled the Los Angeles wildfires that charred 23,000 acres and forced 10,000 people to flee their homes. Those changes in serum proteome are associated with a potential increased risk of cancer, abnormal cell growth, immune system dysfunction and inflammatory response. …The findings are the latest to highlight the health risks facing wildland firefighters, who for decades have actually been barred from wearing protective masks on the fire lines for fear it would limit their work and lead to overheating. The Forest Service recently shifted its policy to allow firefighters to wear masks if they choose.
