Globally, fires in 2025 burned the second-lowest area on record since 2002 and emitted the third-lowest CO2 total. Yet, a third successive year of extreme wildfire emissions prevailed in Canada, and catastrophic fires in Los Angeles, South Korea and Europe killed over 90 people and forced over 300,000 evacuations. At the global scale, land area burned by wildfire has declined in since 2002, mainly owing to reduced savannah burning in Africa. However, wildfires are expanding in extratropical forests, and show increasing intensity combined with extreme socioeconomic and environmental impacts1–3. In these areas, wildfire disasters are exacerbated by human land use and the wildland–urban interface4. Many regions are experiencing episodes of extreme wildfires with high rates of spread and intensity associated with substantial loss of life, infrastructure, or carbon stores, even in years with below-average burned area. These hallmarks define an era of declining global burned area but also of rising prominence of extreme and deadly wildfires.
Suzanne Simard’s 1997 forest experiment did not show trees whispering to each other. It showed something narrower, stranger, and easier to test: carbon that began in the air around a paper birch seedling later appeared inside a neighbouring Douglas fir, after passing through roots and fungal tissue in the soil. The experiment, published in Nature in August 1997, used two carbon labels in the field. Paper birch and Douglas fir seedlings were sealed in plastic labelling chambers, exposed to carbon-14 dioxide or carbon-13 dioxide, left for a nine-day chase period, then harvested and analysed to see where the labelled carbon had gone. The result was not a fairy tale about kindness. It was a measurement. Carbon moved both ways between Betula papyrifera, the paper birch, and Pseudotsuga menziesii, the Douglas fir, with a net gain by Douglas fir in the second year of the field experiment.

MANITOBA — A northern Manitoba tree-planting program is trying to replace trees destroyed by wildfires, but the cancellation of the federal two billion trees program is making that more challenging. In 2016, this forest in Manitoba’s Interlake region, about 300 kilometres northwest of Winnipeg, was devastated by a jack pine budworm infestation. It was starting to regenerate when wildfire ravaged the Devils Lake area in 2021. Areas just north are already burning this spring. Marley Moose says she felt sad when she returned to the forest three years ago as part of a tree-planting program through Nekoté LP, an Indigenous-owned corporation representing seven Swampy Cree First Nations in northern and central Manitoba. According to the Canadian Tree Nursery Association (CTNA), the country is losing trees faster than nature can grow them or people can plant them.
A new logging road project on the Sunshine Coast has drawn concern from local environmental advocates. At the same time, provincial officials say the work is designed to improve access and protect water resources. The Ministry of Forests confirmed to Coast Reporter that it is responsible for the road-building contract tied to Timber Sale Licence A94817. This project will see “just over 4km” of new road constructed to “move industrial traffic away from high-use public roads” and to create long-term access for multiple user groups. The ministry also said that the design has “enhanced overland techniques to minimize impacts to ground water,” along with water-quality monitoring and environmental oversight. However, Elphinstone Logging Focus’s (ELF) Ross Muirhead says the scope of the project is unusual for the region, saying four kilometres of brand new logging road is “unprecedented” on the Coast and that most projects are much shorter.
The start to the 2026 wildfire season has been slow with the number of fires raging across the country well below average, but government officials warn that as the summer progresses there’s a risk things could get much worse. “Despite the fact that we’re seeing so little activity so far this year … this summer retains the potential to be a significant one right across the country,” a government official said Thursday during a technical briefing. The official said that while the wildfire risk is unlikely to result in a record-breaking year like 2023 or 2025, the federal government is forecasting above average conditions as the season progresses. Whether that happens depends, officials explained, on what happens to the weather over the next few months. If the above average temperatures predicted for across the county come to pass, B.C. faces the highest wildfire risk, particularly in July.
Olds College entomologist Ken Fry says forest tent caterpillars are native to Alberta and relatively common, but their populations go through cycles in which they increase dramatically. Municipalities in Alberta are advising residents of an increase in the caterpillars this spring. “Roughly every 10 years populations increase enormously,” he said. The cyclical population explosion is called an outbreak. He said the causes of these cyclical outbreaks are still being studied but are believed to be influenced by weather, health status of trees, and other factors like predators, parasites and disease. Forest tent caterpillars are perhaps best known for the damage they inflict on trees. …”Trees can usually withstand a one-season munching, but when it comes to prolonged persistent defoliation over two, three years, that can result in some twig death or branch death or die back, you know, vulnerability over the winter to winter kill, things like that,” Fry said.
WHISTLER — As Western spruce budworm populations continue to spread through Whistler’s forests at historically unprecedented levels, the BC government is preparing to spray thousands of hectares around the resort municipality with a biological insecticide to blunt the outbreak. The Ministry of Forests is planning to aerially treat areas using Bacillus thuringiensis var. kurstaki (Btk)—a naturally occurring soil bacterium used for decades to control defoliating insects. Taylor Holt, the provincial resource coordinator, said… the aerial overview surveys in 2025 picked up 275,000 hectares of damage. [It’s] nearly three times as much damage as noted ever historically.” …Cheakamus Community Forest (CCF) executive director Heather Beresford, said. “So this is really the only viable treatment.” Still, she acknowledged the decision comes with uncomfortable trade-offs between wanting to prevent dead trees from posing a wildfire risk and protecting local non-budworm species who will be affected by spraying BtK.
Prescribed burning is getting renewed attention in parts of B.C. as communities look for ways to reduce wildfire risk before summer. In Kimberley, B.C., that conversation recently took residents onto the trails near the city’s nature park. The city-led walk gave residents a look at treated areas where crews have been reducing forest fuels. They also heard from local fire officials and wildfire specialists about how planned fire can help protect nearby homes, trails and forested parkland from wildfire risk. Kimberley Fire Department Chief Will Booth says the tour was meant to help residents understand prescribed burning before more fuel management work happens in the city. The local tour comes as prescribed and cultural burning are getting more public attention after years of being less visible. …Bob Gray, a wildland fire ecologist and fire scientist, says warmer temperatures and drought are adding pressure to forests that already have too many trees competing for moisture.
British Columbia’s forests support a diversity of trees, plants, fungi and wildlife, while also providing recreational opportunities, cultural values, and economic benefits to communities. As we recognized the International Day for Biological Diversity on May 22 and Wildfire Awareness Month throughout May, it’s an important time to reflect on the connection between healthy forests, resilient ecosystems, and the communities and wildlife that depend on them. Wildfire resilience and biodiversity are deeply connected. Thoughtful forest management activities, including strategic fuel reduction treatments and cultural and prescribed burning, can help reduce wildfire risk while also creating healthier and more diverse forest ecosystems for generations to come. …Today, FESBC is investing in treatments that reduce wildfire risk around communities, infrastructure and other resources. We are supporting the return of cultural and prescribed burning to the landscape. We are asking questions about how wildfire risk reduction treatments can also support biodiversity and other forest values, such as recreation.
Experts are calling on the B.C. government to halt logging in a Tsitika watershed cutblock on northern Vancouver Island that has been designated for old-growth deferral. But the some First Nations whose territory it falls in say they have their own approach to managing the area sustainably. Pacific Wild, an environmental organization, says B.C. Timber Sales (BCTS) is selling off rare and ecologically significant forests for minimal economic return. In letters sent to BCTS and other government decision-makers in April, the organization presented new data, maps and field evidence showing that cutblock TA1375 — identified by the Old Growth Technical Advisory Panel as a Priority Deferral Area — provides essential habitat for threatened species and stores significant amounts of carbon. The cutblock was auctioned in March despite opposition from scientists, community members and many First Nations whose territories overlap with the Tsitika watershed.
Residents and visitors to Cowichan Bay on Saturday, May 30 take note. A large-scale exercise to help emergency responders train for potential wildfires is taking place in Cowichan Bay from 8 a.m. to 5 p.m. “Please do not be alarmed and help ensure crews can safely complete their training by obeying signage and giving personnel and equipment plenty of space,” said CVRD spokesperson Lisa Moilanen. The exercise will include Shawnigan Lake, Malahat, Mill Bay, Cowichan Bay, Duncan, Sahtlam, Ladysmith, and North Oyster fire departments, as well as BC Wildfire Services and more “working, practicing and learning together to help be aligned, prepared and keep our communities safe,” Moilanen added. The exercise features a scenario where a forest fire is threatening a developed area or community. Moilanen said people will notice emergency vehicles, personnel, traffic cones, and wildfire response activities around Falcon Crescent, and Wilmot, Galdwell, Rondeault, and Hillbank Roads.
HAZELTON – The Forest Practices Board will audit the forest planning and practices of BC Timber Sales (BCTS) and timber sale licence holders in the Kispiox Timber Supply Area (TSA) portion of the Skeena Business Area, starting Monday, June 1, 2026. The audit will examine harvesting, roads, silviculture, protection activities and associated planning. These activities will be assessed for compliance under the Forest and Range Practices Act and the Wildfire Act. BCTS operates throughout the Kispiox TSA, within the Skeena Stikine Natural Resource District. Activities in the audit area are administered from the Hazelton Field Office. The audit area overlaps the territories of the Gitxsan, Wet’suwet’en, Gitanyow, Nisga’a, Lake Babine Nation, Kitselas, and Tsetsaut Skii km Lax Ha First Nations. …The area includes mountainous terrain, rivers and lakes that support recreation, wildlife habitat and important fish populations, including several salmon species, bull trout, Dolly Varden and lake trout.
Three years ago, Barb Round heard heavy machinery chewing through the urban forest behind her home in Campbell River, a small city on east Vancouver Island that bills itself as the salmon capital of the world. Round waved down a man in a hard hat and asked why the excavator was working in the greenway, which is a haven for birds, dotted with pocket wetlands and adjacent to Simms Creek, home to four salmon species. “He explained to me that the property had been sold,” Round, a retired nurse, tells The Tyee. “Everyone in the neighbourhood thought it was protected land.” When residents found out a local developer planned to cut down much of the forest and fill in the wetlands to build a large housing development near the creek, “they were gobsmacked,” Round says.
As bad as things got in Los Angeles in January 2025, when 31 people died and more than 16,000 buildings were destroyed by wildfires roaring into residential neighborhoods, many wildland firefighters look back on the rest of last year as a dodged bullet. Across the nation, according to the National Interagency Fire Center (NIFC), which coordinates the federal wildfire response, the total area burned in 2025 was about two-thirds of the average over the past 10 years. This year is shaping up to be a very different prospect, wildfire experts warn. Key environmental indicators show that the nation is a tinderbox, gripped by widespread drought and with a light snowpack in the mountains that will offer little relief as its remnants melt away. At the same time, upheaval in the federal wildland firefighting effort and the loss of many staff qualified to join wildfire incident teams since Donald Trump took power for the second time have left firefighters deeply concerned about their ability to mount an effective response.
DENVER — A longstanding specter of the Colorado mountains is gaining ground in a new conquest of ponderosa pine forests. An outbreak of the mountain pine beetle is spreading quickly and expected to continue this summer under “prime conditions,” according to a 
NAPLES, Maine — The New England Forestry Foundation (NEFF) is giving out grants to landowners to help preserve some of Maine’s oldest trees. The organization got $4.3 million from the U.S. Forest Service in 2024 to pay loggers to put off cutting late-successional and old-growth forests, which are typically over 100 years old. The first grant was awarded to Chaplin Logging Inc. in Naples to conserve 23 acres of late-successional forest and improve other parts of their land. This type of forest is rare for southern Maine. The one on the Chaplins’ property has been mostly untouched for likely more than a hundred years. According to Brian Milakovsky, senior forester of NEFF, these trees provide a unique habitat for many important species and they’re good for the atmosphere. …Since these trees are being taken out of production, part of the grant is going toward timber stand improvement, removing undesirable trees in landowners’ other, younger forests.
Japan’s forestry sector is at a crossroads. Population decline and cheap imported timber are driving down prices. Forest ownership is fragmented and small-scale, further limiting profitability. The workforce is aging and shrinking. As a result, many forests — planted decades ago, when timber profits seemed surer — are now under-managed, abandoned, or not replanted after being clear-cut. “Especially over the past few years, we have seen a lot of forest owners decide to give up their land,” says Akio Abe, associate director of the Ishinomaki District Forestry Association in Miyagi Prefecture. …Carbon credits, Abe hopes, can provide the financial backing needed to turn the Ishinomaki District woods into a boon, not a burden, for both local landowners and the environment. Together with corporate partners, the foresters are applying for credits certified by an international body, a rarity among forest carbon projects in Japan.
European timber organisations have made a last, united call for changes to be made to the EU Deforestation Regulation (EUDR) before it comes into force this December. Eighteen organisations from various sectors, including timber, panels and packaging groups, called for an EUDR Information System “without flaws and technical constraints, aligned with business practice”. The coalition underlines that the Information System must be operationally workable and aligned with real business practices. The EUDR Information System, which represents the backbone of the traceability feature of the EU regulation, is aimed to prevent products linked to deforestation from entering the EU market. Particular coalition concerns relate to DDS aggregation, technical limitations of the TRACES-based system, the usability of simplified declarations for SMEs and micro-enterprises and the lack of clear procedures in the event of system disruptions or outages.
