Insects and diseases are important disturbance agents in Canadian forests and there is concern that their impacts will intensify under climate change. Here we report on an effort to model and map the climate niches of more than 4000 forest insect and fungus species in Canada – including high-profile pest species that are already, or may soon become, established in the country. This work employs occurrence data from historical, national-scale forest insect and disease surveys. …We further employ national forest inventory products (gridded maps) to summarize forest host volumes at risk of infestation by selected insect and disease species. …We demonstrate use of the products through examples, including brown spruce longhorn beetle, southern pine beetle, oak wilt, and map overlays that show hotspots for bark beetles under current and projected climate. We hope this tool will help pest managers to better understand how these species may respond to projected climate change.
The return of cold and snow at the close of the year typically signal the end of the wildfire season. …Zombie fires, sometimes betrayed by a plume of steam emerging from the bubbling ground in the frozen forest, were once a rare occurrence in the boreal regions that stretch across the far north through Siberia, Canada and Alaska. But in a rapidly heating world, they are becoming increasingly common. The overwintering burns are small – and often hard to detect – but they are transforming fires into multi-year events. …“It is a massive problem,” says Lori Daniels, a professor at the University of BC. Current estimates show that only about 15% of the northern hemisphere is underlain by permafrost, yet these frozen soils contain roughly twice as much carbon than is now in the atmosphere. By burning slowly and at a lower temperature, they release vastly more particulate pollution and greenhouse gas emissions than flaming fires.
The crowd stretched from the doors of City Hall to the Ward Street sidewalk in Nelson to hear guest speaker David Suzuki and other forest ecology advocates at a rally held Nov. 18 in Nelson. …The Broken Promises rally was held simultaneously in Nelson, Victoria, Vernon, Revelstoke, Smithers, Courtenay, Parksville, and Powell River to protest what is seen as provincial government backtracking on the protection of old growth forests, biodiversity and watersheds, and continuing with timber volume as the only priority. …Speaker Suzanne Simard said failure to use that foresight, to respect all life and give back more than we receive, has resulted in climate change, biodiversity loss, and land degradation. …She said the province should stop clearcutting and creating tree plantations that are flammable and subject to erosion. …Slocan Valley ecologist and forester Herb Hammond spoke about secondary forests… That’s where we should get our wood and our employment…
A leaked technical review prepared for a group of First Nations claims British Columbia is greatly overestimating how much timber it can sustainably harvest in a push for short-term economic gains. The previously unreleased report charges that the methods the province uses to calculate how many trees are on the landscape—and therefore how much can be logged—is fundamentally flawed and based on “wildly extreme assumptions” that hurt the long-term health of B.C.’s forests. The report’s authors … only agreed to speak with BIV after it independently obtained a 572-page draft of the report originally dated September 2024. “There’s a strong likelihood that throughout the province we’re cutting almost at twice the rate of what is considered sustainable,” said co-author Dave Radies. The report focuses on the Mackenzie timber supply area… The analysis challenges the methods B.C. uses to determine the annual allowable cut …concluding their numbers are likely double what can be harvested without causing significant long-term damage.
OTTAWA — The Carney government will still pay to help plant a previously announced 52 million trees in New Brunswick, even though hardly any of them are in the ground and the program’s funding has been cancelled. The recent federal budget scrapped a program to plant two billion trees across the country by 2031 in order to find hundreds of millions of dollars in savings. It was a climate change initiative first announced by former Prime Minister Justin Trudeau during the 2019 election campaign with $3.2 billion over 10 years earmarked to carry it out. New Brunswick was one of the last provinces to reach an agreement for its cut of that money. It didn’t sign on until March 2024. A few months after that, the feds and the New Brunswick government announced $71.6 million to plant more than 52 million trees on Crown lands across the province over the next eight years.

BANFF, Alberta – Because of this importance of whitebark pine, Parks Canada is working across the mountain national parks of Banff, Yoho, Kootenay, Jasper, Revelstoke-Glacier and Waterton Lakes to try to give endangered whitebark pine a fighting chance. The higher elevation trees, which can live to be 1,000 years old, are dying off at an alarming rate. Climate change, more than a century of wildfire suppression and mountain pine beetle are all playing a role, but the biggest threat comes from white pine blister rust. …One clear sign of infection is orange blisters on the bark. McLellan said less than one per cent of whitebark pine are naturally resistant to the rust. …Charlie McLellan said last summer about 6,500 rust-resistant saplings were planted in the Banff National Park field unit and in Kootenay National Park – made up of whitebark pine and limber pine, another species recommended to be listed as endangered.
The best time to plant a tree is 10 years ago. Or 20. That’s what I was told by the two retired foresters who put 2,000 one-year-old seedlings in the ground on my farm back in 2017. I had signed on with what was then called the 50 Million Tree program run by Forests Ontario, which subsidized plantings for private landowners. …the Forests Ontario program made tree planting easy. At 40 cents a stem, those trees cost me $800. While 2,000 trees seems like a lot, they cover just under one hectare. We got the seedlings in the ground a couple years before Doug Ford nixed the initiative in 2019. But then, Justin Trudeau created the 
The provincial government has awarded a pair of contracts to build firebreaks in areas of the Avalon Peninsula ravaged by this summer’s historic wildfire season — fires that forced hundreds of people from their homes and destroyed more than 200 structures. A firebreak is an intentionally created gap where burnable material, like vegetation and trees, are cleared in an effort to stop a fire from spreading further by removing flammable materials that could feed it. It was employed as a firefighting tactic against the Kingston, Martin Lake and Paddy’s Pond fires. According to a list of recently disclosed provincial government procurement contracts, Conception Bay South-based Platinum Construction Company Limited was awarded a $51,600 contract. Another contract, valued at $419,983.35, was awarded to Jerseyside-based Tier 1 Capital Corporation to build firebreaks in Burnt Point and Salmon Cove. Both contracts were awarded shortly after the PC party won a majority government on Oct. 14.
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. [to access the full story an E&ENews subscription is required]
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.
At face value, the amount of forest in Australia is officially increasing, and has been since 2008. But if an old-growth tree is felled in a forest and seedlings grow elsewhere, is the official account ecologically sound? Not according to new analysis, which suggests that the way Australia calculates forest cover obfuscates the impacts of ongoing deforestation. Australia calculates forest cover as a net figure, in which forest losses are “netted off” against forest gains. That is problematic, according to a report led by Griffith University’s Climate Action Beacon, because new forests do not store as much carbon or have the same wildlife benefits as established forests that are being destroyed. Prof Brendan Mackey of Griffith University, one of the study’s co-authors, described measuring forest losses and gains in net terms as “an accounting sleight of hand”.
